What Mould Is And Why Cleaning The Surface Is Only The Start
Mould is usually a moisture symptom, not a “dirty wall” problem. Cleaning the surface can remove what you can see, but to treat mould at source you need to address why it grew there in the first place. The real question is whether your wall can stay dry enough, often enough, to stop regrowth—and whether the plaster underneath the paint is still sound once the moisture source is controlled.
Mould spores are present almost everywhere. What turns background spores into visible growth is repeated dampness on a surface that stays cool, slow to dry, or poorly ventilated—corners, window reveals, behind furniture, and areas with limited airflow. In most homes, that dampness tends to come from one of three routes: condensation, penetrating damp, or rising damp. They can look similar at first glance, but they behave differently and need different fixes.
Common types of damp that lead to mould
Condensation, penetrating damp and rising damp can all produce mould, but they don’t do it in the same way. If you match the treatment to the wrong mechanism, you can spend money twice: once on a “fix” that doesn’t work, and again on the repair you needed in the first place. The aim is to identify the moisture route, stop the re-wetting, and then decide what finishes can realistically be kept.
Condensation is moisture created inside your home (showers, cooking, drying clothes, breathing) that turns into water on colder surfaces. It often shows up in corners, behind wardrobes, on external walls, and around windows. Heavy window condensation and mould returning in the same spots during colder weather are common clues.
Penetrating damp is water entering through defects in the building envelope or internal leaks. It tends to be more localised and can track to roof defects, gutters and downpipes, cracked render, failed sealant around frames, or plumbing leaks. It often worsens after rain or appears around kitchens and bathrooms.
Rising damp is moisture travelling up from the ground, usually affecting the lower parts of walls. It’s often associated with tide marks and salts. Those salts matter because they can keep damaging finishes even after you redecorate, and they can make plaster fail again if the wall hasn’t been properly treated and specified.
Typical signs that plaster may be affected, not just the paint
Common signs of damp and mould include yellow-brown water staining, blistering or flaky plaster, tide marks, visible mould, musty smells, peeling wallpaper, salts showing through finishes, and excessive window condensation. You might also notice cold patches, soft areas near skirtings, or plaster that powders when you rub it lightly.
Here’s the simple rule that protects your time and money: if the plaster is blown (hollow-sounding or detached), crumbly/soft (dents easily, powders, breaks away), or heavily salt-contaminated (white residue/crystals, repeated bubbling and flaking after repainting), it often needs removing and replacing rather than just being cleaned, sealed and painted. In those cases, you’re not “improving a surface”—you’re trying to build on a base that’s already failing.
Different damp mechanisms damage plaster in different ways, so decisions about re-plastering should follow proper diagnosis, not guesswork. You’re aiming for a stable substrate that can dry and stay dry, not a quick cosmetic reset.
Health Risks From Damp And Mould You Shouldn t Ignore
Damp and mould aren’t just cosmetic, because prolonged exposure can affect your health and day-to-day wellbeing. The risk tends to climb when mould keeps returning—because recurrence usually means the moisture conditions are still active. If you’re repeatedly cleaning, redecorating, and living in the same damp air, the exposure cycle continues, and the building fabric often keeps degrading in the background.
You don’t need panic; you need a plan that stops the problem repeating.
The practical point is this: treating mould properly is partly a health decision and partly a building decision. If the wall stays damp, you get repeat growth. If finishes keep failing, you keep disturbing contaminated surfaces. Breaking the cycle is about removing the moisture conditions, then reinstating finishes only where they’re genuinely needed.
How damp and mould affect health
Damp and mould can affect your airways and lungs, and can also irritate your eyes and skin, which is one reason to get a mould survey first rather than relying on surface cleaning alone. Living with persistent damp can also impact your mental health through stress, disrupted sleep, and the feeling that your home isn’t fully under control. Prolonged exposure can contribute to serious illness and, in the most severe cases, has been associated with death. If you already have asthma or allergies, or you’re supporting very young children or older adults, symptoms can show up faster and feel more severe.
Health risks increase when mould is allowed to recur, because recurrence usually means longer exposure and a steady build-up of spores and irritants in the room. From a building perspective, repeat growth is evidence of an ongoing moisture pattern, not a one-off patch. That’s why the “do you re-plaster?” decision matters: if you leave failing or contaminated plaster in place, you can end up with a surface that’s harder to keep clean, harder to dry, and more likely to trigger repeated problems.
Why official guidance has become stricter
Recent national guidance on damp and mould in the home was updated in August 2024 and is published on GOV.UK by health and housing departments. The direction is clear: reports should be taken seriously, investigated properly, and addressed in a way that removes the conditions for recurrence rather than relying on repeated surface cleaning.
The death of Awaab Ishak is widely referenced as a driver for landlords and housing providers to act urgently on reports of damp and mould. For you, the takeaway is practical: if mould keeps coming back, repeated cleaning and repainting isn’t a strategy—it’s a sign the underlying moisture route needs proper attention, and that damaged finishes may need reinstating once the cause is controlled.
Do I Need To Re d0plaster After Treating Mould?
Often, no. If you have a small, early mould patch on otherwise sound plaster, you can usually clean it safely, fix the moisture source, and monitor without immediate re-plastering. Re-plastering is more likely when plaster is soft, blown, crumbly, deeply affected, salt-contaminated, or linked to long-term rising or penetrating damp. Re-plastering alone will not stop condensation returning, or stop mould returning, if leaks or damp in the wall aren’t resolved first.
A useful way to decide is to separate “appearance” from “performance”. A wall can look better after cleaning and paint, yet still be damp-prone, salt-contaminated, or structurally unsound underneath. The goal is a finish that stays stable and dryable—not one that needs constant rescuing.
Situations where cleaning may be enough
If the mould is small, recent, and sitting on firm plaster (no hollow sound, no softness, no persistent staining), cleaning can be enough once you’ve removed the moisture driver and begun to treat mould at source. This is common with condensation mould in a cold corner, around a window reveal, or behind furniture where airflow is poor. When you improve ventilation, reduce indoor moisture, and keep steadier background warmth, the surface often stabilises and regrowth stops.
A quick “sound plaster” check is practical: does the area remain firm, dry-looking, and free from repeated bubbling paint, flaking, staining, or musty odours after the room’s moisture conditions have changed? If it does, you can usually redecorate without disturbing the plaster.
Micro-scenario: you find a small patch behind a wardrobe on an external wall. You pull the furniture forward, keep vents clear, and run extraction properly in the adjoining bathroom. If the patch doesn’t return over the next few weeks, the wall was telling you “airflow and surface temperature” rather than “deep damp in the fabric”.
Signs you should plan for re d0plastering
Plan for re-plastering when the plaster is no longer a reliable base or is contaminated in a way that keeps breaking finishes down. Common criteria include:
- Blown plaster: (hollow-sounding, detached, cracked away from the background).
- Soft or crumbly plaster: (powdering, denting easily, breaking down when rubbed).
- Salt contamination: (white residue/crystals, repeated bubbling and flaking after repainting).
- Deeply ingrained mould: that returns quickly even after conditions improve, suggesting the surface isn’t cleanable or stable.
- Long-term damp: linked to rising damp or penetrating damp, where the wall fabric has been repeatedly wetted.
Re-plastering is a reinstatement step, not the “cure”. If condensation, leaks, penetrating damp, or rising damp are still active, new plaster can become damp again and you can be back where you started. If you suspect rising damp or penetrating damp, a qualified damp surveyor helps you avoid unnecessary or ineffective re-plastering by specifying the right remedial sequence and a compatible plaster system.
If you’re buying or selling, significant historic mould or damp affecting plaster can create friction during surveys and mortgage decisions. Surveyors and lenders are usually reassured by a clear chain of logic: the cause was identified and addressed, damaged material was removed where necessary, and reinstatement followed in the correct order with sensible monitoring.
How To Treat Small Patches Of Mould Safely Before You Think About Plaster
You can treat small patches of mould safely, but think of it as controlled clean-up rather than “problem solved”, and in some cases a mould survey first may be the more sensible step. Your aim is to remove visible growth without spreading spores, protect your lungs and skin, and then change the moisture conditions that fed the mould in the first place. If the patch is large, persistent, or the surface is breaking down, cleaning alone often becomes a repeating cycle.
A good boundary is simple: keep DIY cleaning to small, contained areas on sound surfaces. If the mould keeps returning, or you see signs of damp-damaged plaster, escalate it so the cause is investigated properly. That shift—from repeated cleaning to proper diagnosis—is what prevents wasted disruption and repeat exposure.
Safe DIY mould removal steps
For small patches, your first priority is safety and containment. Wear rubber gloves, goggles, and a mask, and ventilate the room during and after cleaning by opening windows (and doors where safe) to create airflow. This reduces your exposure and helps clear both spores and cleaning-product fumes.
Use a purpose-made mould-removal spray and follow the manufacturer’s instructions, including contact time. Do not brush or vacuum mould, because that can spread spores into the air and around the room. After cleaning:
- Bag and bin used cloths and disposable masks.
- Wash reusable gloves and goggles in soapy water with a small amount of bleach.
- Keep the room ventilated until surfaces are fully dry.
Micro-scenario: you wipe a patch and the paint comes away, leaving powdery plaster that rubs off onto your fingers. That isn’t “stubborn mould”. It’s a sign the surface is failing, so the next step is to stop scrubbing, assess what’s happened to the plaster, and work out why it stayed damp, especially if you need to stop condensation returning.
When tenants should escalate to a landlord
If you’re a tenant and the mould is widespread, persistent, or linked to a suspected defect, report it formally rather than relying on repeated DIY cleaning. Take close-up and wider photos, and include related signs such as staining, flaking plaster, tide marks, salts, or heavy condensation. Keep a simple timeline of dates, what you reported, and what action followed.
DIY cleaning does not replace the landlord’s duty to investigate and remedy the underlying causes of damp and mould. Cleaning can reduce visible mould temporarily, but it does not fix a roof leak, defective guttering, a bridged damp-proof course, inadequate extraction, or a plumbing issue. If mould returns after reasonable cleaning and ventilation, that pattern supports escalation and proper remedial work—not another cosmetic pass.
Fixing The Cause So You Don t Have To Re d0plaster Twice
If you want a result that lasts, the sequence matters: stop the moisture route, allow the building to stabilise, then repair and reinstate finishes. Re-plastering is disruptive, and it becomes far more disruptive if it’s done before the moisture problem is under control. The goal is one clean cycle of repair, not a loop of patch, paint, fail, repeat.
Stop the re-wetting, then rebuild the finish once it can stay stable.
It’s also common for more than one moisture input to exist at the same time. Condensation can be obvious while a slow plumbing leak or an external defect quietly feeds dampness too. A sensible approach is to check for leaks and structural routes first, then tighten everyday moisture control so the room behaves differently day-to-day.
Checking for leaks and structural damp
If you suspect penetrating damp, check roofs, gutters, downpipes, window and door frames, and internal plumbing for leaks. Look for patterns: staining that worsens after rain, dampness that lines up with a bathroom or kitchen, or patches that map to a gutter, downpipe, valley, or pipe run.
A quick checklist helps you catch common causes early:
- Check guttering and downpipes for overflow, leaks, or blockages.
- Inspect roof defects and flashing where damp tracks down internal walls.
- Review window and door seals where staining appears around frames.
- Check internal plumbing and waste pipes near the affected area.
If you suspect rising damp, involve a qualified surveyor so the damp-proof course can be examined and signs such as tide marks, salts, and bridging can be assessed before re-plastering. Rising damp and salt contamination often need specific remedial steps and a compatible plaster system; plastering over contaminated masonry is a reliable route to repeat failure.
Controlling condensation and everyday moisture
If condensation is part of the problem, controlling it often determines whether you can keep existing plaster or whether finishes keep failing. Moisture from showers, cooking, drying laundry and breathing builds up indoors. If it can’t escape through ventilation, it condenses on cold surfaces and creates consistent dampness—especially in corners, behind furniture, and around windows.
Practical actions include drying clothes outside where possible, venting tumble dryers, covering pans when cooking, and avoiding unflued gas or paraffin heaters. Pair that with ventilation and heating habits: use extractor fans, open windows where safe, keep vents clear, and maintain steady background warmth at roughly 18–21°C to reduce cold surfaces where condensation forms.
When condensation is controlled, mould usually stops returning because the environment stops feeding it. That makes any later re-plastering more durable, because you’re reinstating onto a wall that’s behaving properly, not one that’s still being repeatedly wetted.
Landlord And Tenant Responsibilities Around Damp, Mould And Damaged Plaster
In rented homes, damp, mould and damaged plaster are habitability issues, not just decoration issues. Decisions about re-plastering should be made in line with legal duties to keep the property fit for human habitation, not simply cosmetic preference. If the plaster is compromised and contributing to a damp and mould hazard, reinstatement is part of remedial repair once the cause is addressed.
Good outcomes are usually the ones that are documented and sequenced. A clear record of what was found, what was done, and why it was done protects you whether you’re living in the property, managing it, or paying for repairs.
Legal duties to act on reports
Landlords are expected to act promptly on reports of damp and mould and should not wait for medical evidence before taking action. National guidance summarises key legislation for landlords, including the Housing Act 2004, Environmental Protection Act 1990, Homes (Fitness for Human Habitation) Act 2018, Landlord and Tenant Act 1985, the Decent Homes Standard and relevant Building Regulations. The shared theme is that damp and mould are treated as hazards that require investigation and remedy.
Non-compliance can lead to enforcement action, penalties, and in serious cases prosecution. In practical terms, that means “paint over it” is not an adequate response where damp conditions persist or where plaster is blown, salt-contaminated, or repeatedly failing. Restoring a stable, cleanable surface is part of making the home safe and fit—not an optional upgrade.
How documentation supports future disputes
Photograph and document the condition of mould-affected plaster before removal, both for landlords planning remedial work and tenants reporting problems. Take close-up photos of mould, wider photos showing location, and photos of related signs like staining, flaking plaster, tide marks, salts, and heavy condensation on windows. Keep dates and a simple timeline of reports, visits, and actions, and retain copies of messages and inspection notes.
Documentation keeps the decision defensible. Instead of “we replastered because it looked bad”, you can show observed damage (soft, blown, salt-contaminated plaster), the likely moisture mechanism, what repairs or controls were put in place, and why reinstatement was necessary to restore a stable surface.
Here’s a short snapshot to keep decisions practical rather than emotional.
| Situation you can observe | Likely next best step | Why it matters |
|---|---|---|
| Small patch, solid surface, condensation pattern | Clean safely + improve ventilation and steady warmth | Removes growth and reduces conditions mould needs |
| Damp linked to rain or plumbing route | Repair defects first, then reassess finishes | Stops re-wetting before decoration or plaster repairs |
| Low-wall tide marks or salts | Arrange inspection before re-plastering | Avoids plastering over contamination and repeat failure |
Checking Results After Treatment And Planning Any Re d0plastering
Re-plastering becomes safer and more durable when you verify that the cause has been controlled and the wall is behaving differently. This stage is about timing and proof, not optimism. If you finish too early, you risk sealing moisture into a wall, trapping salts behind a new system, or decorating onto a surface that still wants to fail.
Micro-scenario: you clean a corner, repaint it, and it looks fine for a fortnight—then a musty smell returns and a faint shadow appears in the same spot. That isn’t “bad paint”. It’s an early warning that moisture conditions haven’t stabilised, so finishing now is likely to pull you back into the same cycle.
Post d0treatment inspections
A sensible checkpoint is to inspect around six weeks after remedial work to confirm that damp and mould have not returned before final re-plastering and decoration. This isn’t a fixed rule for every property, but it’s a practical timeframe where recurrence patterns often reveal themselves.
Make monitoring deliberate. Watch for recurring condensation on windows, damp patches, musty smells, or new mould specks—on the treated area and on neighbouring cold spots where moisture can “shift” once airflow changes. Keep photos from the same angles so you can compare, and note what changed (heating pattern, ventilation use, furniture position) so you can link cause and effect.
Some councils and social landlords are increasingly using indoor air-quality monitors and humidity sensors to track persistent damp problems. You don’t need specialist kit to follow the principle: consistent observation and simple records help confirm whether the environment has stopped feeding mould.
When to bring in a specialist damp contractor
Bring in a specialist damp contractor or qualified surveyor when mould returns despite reasonable ventilation and moisture control, when you suspect structural damp (penetrating damp, rising damp, hidden leaks), or where previous treatments have failed. The aim is to stop spending on repeated cleaning and redecorating and start spending on a diagnosis and specification that solves the cause and protects your finishes.
A proper specialist report should cover damp diagnosis, moisture readings and observations, the likely cause, recommended treatment, and a clear specification for plaster systems and reinstatement sequence. It should also set scope boundaries—what’s included, what’s excluded, and what needs verifying—so you don’t re-plaster too early, re-plaster unnecessarily, or re-plaster in a way that sets you up for repeat failure.

Frequently Asked Questions
Do I need to re-plaster after treating mould, or can I just clean and repaint?
You only avoid re-plastering when damp and mould are superficial, the cause is fixed, and the wall build‑up is still performing properly.
When cleaning and repainting is usually enough
If the issue is clearly linked to day‑to‑day condensation – steamy bathrooms, cold corners, behind wardrobes – and the patch is small and recent, a “light touch” approach can be reasonable. You clean with a proper mould‑wash, sort the basics (ventilation, background heat, drying clothes sensibly), let the area dry right through, then use a suitable stain‑blocking primer and quality paint. If there’s no obvious bulging, deep cracking or musty smell over the next heating season, you’ve probably dealt with a surface problem and can treat it as part of normal decoration rather than a building repair.
When re-plastering is the smarter long-term decision
Re‑plastering becomes the better choice when the room has a history of damp and mould, decorations fail quickly, or survey reports start talking about structural damp, “salts” or long‑term moisture. At that point, the issue with re-plastering when damp and mould keep coming back isn’t “can I get away with paint?” but “do I want to keep paying to redo this room every couple of years?”. Stripping back and specifying new plaster adds cost and disruption now, but it lets you pair the right backing system with the actual moisture source and gives lenders, buyers and insurers more confidence in the property. Think of cleaning and repainting as short‑term damage control; think of re-plastering as part of a full building moisture control and repair plan when you want the problem off your plate for good.
How do I tell if mould has damaged the plaster rather than just the paint?
You work out whether mould has damaged the plaster by how the wall feels, sounds and behaves once it has been cleaned and allowed to dry.
Simple hands-on checks you can do yourself
Start with touch. After you’ve cleaned off the damp and mould and given the wall time to dry, press different spots with your fingertips. Sound plaster feels firm and “stone‑like”; damaged areas often feel soft, spongy or gritty. Then try a tap test with your knuckles or a small tool. A sharp, consistent knock usually means the plaster is bonded well to the substrate, while a dull, hollow or drum‑like sound suggests it has blown away from the backing and lost strength. Finally, watch what comes away when you lightly scrape a suspect patch: if only thin paint flakes, the base is probably fine; if thicker chunks of plaster and backing crumble, the surface itself is breaking down.
Once you’ve done the touch and sound checks, stand back and look at the pattern. A low “tide mark”, bubbling finishes or white, powdery deposits are strong clues that you are dealing with more than tired paint. Those are classic signs of rising damp and salt contamination, where moisture has moved through the wall and left hygroscopic salts in the plaster. Even when you clean off visible growth, those salts can keep pulling moisture from the air, leaving the area patchy or cold to the touch. Guidance such as BRE Digest 245 supports using this mix of simple checks and, where needed, moisture readings to judge the condition of the substrate. These observations don’t replace a professional survey, but they give you a solid sense of whether you’re looking at sound plaster that can be saved, or a failed layer that needs a specialist to design a proper repair.
What are my landlord’s responsibilities if mould keeps coming back and the plaster is crumbling?
If mould keeps returning and the plaster is crumbling, your landlord’s responsibilities move into the territory of legal fitness for habitation, not just cosmetic touch‑ups.
How the law views recurring damp and mould in rented homes
Modern housing law treats significant damp and mould as a real health and safety concern, especially where children, older people or those with breathing issues live. Under the Housing Act 2004 and the Homes (Fitness for Human Habitation) Act 2018, landlords must provide homes that are reasonably free from serious hazards, and defective plaster with visible mould is squarely in scope. When the same areas keep failing or flaking, it points to an unresolved damp source rather than everyday lifestyle. At that stage, “wipe it off and repaint” falls short of what is expected of landlord responsibilities in the private and social rented sectors.
Practical steps you can expect your landlord to take
You are entitled to expect a proper diagnosis and repair plan, not just another coat of paint. That usually means your landlord arranging an inspection to check for leaks, rising damp, condensation or other moisture sources, and then commissioning works that tackle both the cause and the damaged finishes. In many cases, that includes removing failed plaster and specifying a reinstatement system that suits the building and its use. Landlords often bring in independent damp specialists so they can show they’ve acted reasonably and in line with current guidance. If you report problems in writing, keep photos and give them a fair chance to respond, you are building a clear record that helps housing officers or advice services support you if things are not put right.
Why is it risky to re-plaster or redecorate straight after mould treatment?
It’s risky because new finishes can seal in moisture and salts from rising damp, penetrating damp or heavy condensation, setting you up for a repeat of the same damp and mould.
Hidden moisture that outlasts the visible mould
Once you’ve treated surface mould, it’s easy to assume the problem has gone with it. In reality, masonry often holds on to water well after the last black spot disappears. After rising damp or leakage, that moisture can sit deep in the wall for weeks or months. If you apply new plaster or tight, low‑permeability paint too soon, you cap a damp structure with a fresh skin. The trapped moisture then looks for a way out, leading to blistering, peeling and stubborn discolouration on brand‑new work. Where salt contamination is involved, those salts can migrate into new plaster and quietly attack it from within, which is why standards such as BS 6576 place so much emphasis on correct drying and reinstatement.
A staged approach that respects drying time
A safer route is to treat the moisture and the mould, then deliberately pause before you even think about final finishes. During that pause, a specialist can monitor moisture levels, look for persistent cold spots and decide what type of plaster system is appropriate for that wall and that property. In disciplined damp proofing and building moisture control, this staged approach is normal, especially after penetrating damp or structural work. Yes, it extends the project slightly, but it drastically lowers the odds of failed paint, wasted money and renewed health worries. If in doubt, it’s better to ask for a drying and monitoring plan than to rush ahead and pay twice.
When should I call a damp specialist to specify re-plastering after mould?
You should involve a damp specialist when simple lifestyle fixes have failed, visible damage is spreading, or any report mentions structural damp or salts.
Signs you are beyond “wipe it off and see”
If you have improved ventilation and heating, stopped drying clothes indoors and still see damp and mould returning in the same spots, the issue has moved beyond normal occupancy. The same is true if areas of plaster are cracking, bulging, flaking in thick layers or staying cold and clammy compared with the rest of the room. Add in any mention of rising damp, penetrating damp or salt contamination in a survey, and you have a clear signal that guessing is over. At that stage, you are deciding how to protect your health, your property value and, if you rent homes out, your legal position as a landlord or managing agent.
How Sussex Damp Experts turn that into a clear plan
When you ask Sussex Damp Experts to help, we don’t just look at the stain and quote for new plaster. We trace the moisture source, test for salts, review ventilation and check how the rest of the building behaves. You receive a written specification that explains where re-plastering is actually needed, what materials suit your walls and how long to allow for drying before decorating. That makes it easier to brief your builder or decorator and to show insurers, surveyors or tenants that the problem has been taken seriously. If you want confidence instead of trial and error, now is the time to book a damp and mould consultation and let a specialist design the right repair.
My survey report mentions salts and rising damp – does that mean all the plaster has to come off?
A survey that mentions rising damp and salt contamination is a red flag, but it usually calls for targeted removal of affected plaster, not automatically stripping every wall to bare brick.
Understanding what “salts present” really means
Those comments mean moisture has carried dissolved minerals up through the wall and into the finishes. Over time, the salts accumulate in the lower zones of the plaster and can pull moisture from the air even after a new damp‑proof course or other works have been installed. That is why many damp‑remedial specifications call for hacking off contaminated plaster to a clearly defined height – often a bit above the highest salt band – and then reinstating with a suitable damp‑resistant or breathable system. Higher up the wall, where finishes are sound, dry and free of visible damp and mould, plaster can sometimes be left in place if it passes moisture and salt checks as part of a structured repair plan.
Making a sensible decision about scope and disruption
From your point of view, the real question is how much disruption is justified to avoid ending up in the same position later. Removing too little plaster risks ongoing staining, musty smells and awkward conversations with surveyors, buyers or lenders at the next sale or remortgage. Stripping everything without evidence drives cost and upheaval that may not be necessary, especially when re-plastering when damp and salt contamination have not been properly assessed. Health guidance from bodies such as the UK Health Security Agency treats damp and mould as a genuine concern, so cutting corners is rarely worth it. Sharing the report with an experienced damp specialist allows them to turn that technical language on rising damp and salt contamination into a clear, measured scope of work that keeps both your walls and your finances under control.
