What good records look like for a damp complaint in the UK
You keep effective records by building a clear timeline that shows what is happening, when you reported it, how your landlord responded, and what the results were. A good record set makes it easy for a landlord, Environmental Health officer, or Housing Ombudsman to see the pattern without trawling through random screenshots and messages. It turns “you never told us” disputes into simple questions of dates, actions, and outcomes instead of arguments about memory.
What your records need to prove
At heart, your records are there to answer five basic questions:
-
What is the problem?
Where the damp or mould is, how extensive it is, and how it has changed over time. -
When did it start and how long has it gone on?
First signs, periods when it worsens (for example, after rain or in winter), and any “quiet” phases. -
When and how did you tell the landlord or agent?
Dates, channels (email, portal, letter, text), and any reference numbers. -
What did they do in response?
Inspections booked, visits carried out, advice given, repairs attempted, and missed appointments. -
What has been the impact on how you live in the home?
Rooms you cannot use properly, damage to belongings, extra costs, and any effect on health or daily life.
If somebody independent can read your notes and answer those five points in under ten minutes, you are very close to having a solid “evidence pack”.
Keeping the work manageable
You do not need a lawyer’s bundle or a complex app to achieve this. For most people, the simplest workable system is:
- One master log: (a spreadsheet, note‑taking app, or ruled notebook).
- One evidence folder: on your phone, computer, or cloud drive, with a matching paper folder if you like.
- A short weekly slot: to update it, rather than trying to write everything up from memory months later.
A specialist firm will often start by asking for exactly this: a short log and a small number of well‑labelled photos, rather than hundreds of unorganised images. If you aim for clarity rather than volume, you protect yourself without turning record‑keeping into a second job.
You might, for example, decide that every Sunday evening you will take ten minutes to update your log and move that week’s photos into the right folder. Over a couple of months, this becomes a simple habit. When someone later asks “when did this start?” you are not guessing; you can open your log and show the first entry and how things have changed since.
Clear, calm records turn a stressful situation into a set of facts that people have to deal with.

Book a Survey for Evidence →You make your life easier by deciding on your structure before the situation drags on. A basic log and a tidy folder system mean you are not hunting through WhatsApp, email, and camera rolls every time someone asks what happened when. Once this is in place, keeping it updated usually takes only a few minutes at a time.
Creating your master log
Your log can be a spreadsheet, a note app, or a handwritten table. What matters is that you use the same headings each time and add entries as you go. A practical layout looks like this:
- Date and time: – when you noticed something or when an event happened.
- Location: – room and exact area, for example “Bedroom 2, external wall behind wardrobe, lower left corner”.
- What you saw or experienced: – short, factual description: “Black mould patch about A4 size”, “paint bubbling”, “strong musty smell on entering room”.
- Photo or video IDs: – the filenames of any images you took that day.
- Who you told and how: – “emailed agent repairs@…”, “reported on portal”, “phoned landlord”.
- What they said or did: – “auto‑reply received”, “inspection booked for 12 March”, “no response”.
- Next step or outcome: – “waiting for visit”, “contractor attended, washed wall”, “no change after three weeks”.
Here is how a single line might look in a simple spreadsheet‑style log:
| Date / time | Location | What happened |
|---|---|---|
| 2026-02-15 08:10 | Bedroom 2, external wall by window | Black mould patch about A4 size; photos 01–03 |
Aim for one issue per line. If you have damp in two separate rooms, use two entries.
Naming and storing your files
Good file names mean you can find things quickly without opening every image. A simple pattern might be:
2026-02-15_bedroom2_external-wall_mould_01.jpg
Try to be consistent with:
- Date first: (year‑month‑day) so files sort in order.
- Room: and surface or feature (ceiling above window, chimney breast, skirting board).
- A short keyword (mould, damp patch, leak) and a sequence number if there are several images.
Create one main folder for this issue, for example:
- `Damp – 24 Acacia Road – Bedroom 2 external wall`
Inside that, have subfolders such as:
- `01_Log` (your spreadsheet or notes)
- `02_Photos_and_Video`
- `03_Landlord_and_Agent_Contact`
- `04_Costs_and_Damage`
- `05_Health_and_Wellbeing` (if relevant and if you choose to record it)
This kind of structure makes it much easier to share only what is relevant if a landlord, council officer, or advisor such as Sussex Damp Experts asks to see your evidence.
You might find, for instance, that when a new housing officer takes over your case, you can email just your log and a link to the relevant subfolders instead of forwarding months of mixed messages. That first impression of order and clarity often sets the tone for the rest of the conversation.
Capturing photos, video, and screenshots that actually help

You document damp effectively by taking repeatable photos and videos that show exactly where the problem is, how big it is, and how it changes over time. Random close‑ups with no context are easy to dismiss; a consistent set of images makes it much harder for anyone to claim they cannot see what you are talking about.
A simple three‑shot photo routine
For each affected area, use the same basic pattern every time you pick up your phone or camera:
- Wide shot – stand in the doorway or opposite corner and photograph the whole wall or ceiling so the viewer can see the room layout and main features.
- Mid‑range shot – move closer so the affected area fills a good part of the frame, but nearby features such as a window, radiator, or wardrobe are still visible.
- Close‑up shot with scale – hold a ruler, tape measure, or even a coin next to the mould or staining so someone can judge size and detail.
This combination answers three key questions in seconds: where it is, how big it is, and what surface it is on. Use the same order every time so you can compare like‑for‑like as weeks go by.
Showing progression and “after” results
Repeat photos are more powerful than dramatic descriptions. To show change over time:
- Stand in the same place for your wide and mid‑range shots each time.
- Keep the camera at similar height and angle; picking a floor tile or skirting joint as your foot position helps.
- Take photos on a regular pattern, such as weekly, after heavy rain, or after a repair visit.
- For “after” works, stand where you took your original “before” shots and match the framing as closely as you can.
Screenshots can also be valuable. If you report damp by text or messaging app, screenshot the conversation with the date and time clearly visible, then save it into your 03_Landlord_and_Agent_Contact folder. This stops important messages from getting lost if a phone is replaced or an account changes.
Imagine, for example, that you notice mould around the bedroom window in early October. You take your three photos that weekend and log them. After you report the problem, you repeat the same set after the first heavy rain, then again after a contractor visit. By December, you can show a short sequence of pictures from the same angle that proves the patch has grown back in the same place, even after work was done.
Making video walk‑throughs useful
If you record video, think of it as a short guided tour for someone who has never seen the property:
- Start by saying the date, room name, and what you are about to show.
- Move the camera slowly and steadily, without jumping around.
- Pause briefly at each affected area so the viewer can see the detail.
- Mention any obvious context: “You can see this is above the window”, “this corner is on the external wall”.
Well‑planned photos and videos, saved with clear filenames, often do more to move a damp complaint forward than long written descriptions.
Using humidity, temperature, and moisture readings without getting overwhelmed

You do not have to become a building scientist to use basic measurements to support your complaint. A few simple, consistent readings can help distinguish between condensation behaviour and issues such as leaks or penetrating damp. The key is to measure in a fair way and record enough history to show a pattern, not to drown yourself in data.
Basic indoor readings that help
If you have a simple combined thermometer and humidity metre, you can log:
- Room name: – “Bedroom 2”, “Bathroom”.
- Position: – “Centre of room, chest height, away from windows and radiators”.
- Temperature (°C): and relative humidity (RH%).
- Date and time: of each reading.
Pick one or two times each day that you can stick to, such as first thing in the morning and late evening. Add short notes for anything unusual, for example “just finished shower”, “windows open for 20 minutes”, or “drying clothes on airer”.
Over a fortnight or so, this helps show whether the room is often cold and humid, or whether damp patches appear even when conditions are reasonable indoors.
When and how to use other devices
If you use a dehumidifier, it can be useful to jot down when it was running and roughly how much water it collected. This shows that you are taking reasonable steps to manage moisture, without accepting blame for any building faults.
If you or a contractor have a moisture metre:
- Note the make and model.
- Record where readings were taken (“living room chimney breast, 0.5 m above skirting”).
- Keep readings in your log and, if possible, on a simple sketch or printed floor plan.
Remember that many moisture metres are better for comparing one area with another than for giving an exact percentage that proves a legal threshold. Your goal is to show a consistent method and obvious patterns rather than argue about single numbers.
If you ever feel out of your depth with readings, a short discussion with a specialist such as Sussex Damp Experts can help you decide what is worth continuing and what you can safely stop doing.
Recording health and wellbeing effects in a careful, proportionate way

You strengthen your position when you can show not only that there is damp, but also how it affects daily life. At the same time, you protect yourself and others by keeping health records proportionate and private. The aim is to illustrate impact, not to turn your log into a full medical file.
A simple impact diary
Alongside your main log, you might keep a brief diary noting:
- Date: and, if helpful, time.
- Who was affected: – “me”, “child”, “partner”.
- What happened: – “woke up coughing”, “slept on sofa because bedroom smelled musty”, “took day off work to wait for contractor who did not attend”.
- Link to damp situation: – “in mould‑affected bedroom”, “after using dehumidifier all night”.
Keep entries short and factual. Avoid guessing at diagnoses; for example, “tight chest overnight in damp bedroom” is clearer and safer than “my asthma is definitely caused by this wall”.
You might notice, for example, that your child’s coughing gets worse on nights when the bedroom window is too wet to open and there is visible condensation on the walls. Three or four short diary entries over a month can show that pattern much more calmly than a single, stressed email written when things feel at their worst.
Handling documents and privacy
If you already have letters, fit notes, or summaries from healthcare professionals that mention breathing problems or other issues, you can keep copies in the health section of your evidence folder. Think about:
- Who really needs to see them: – sometimes an adviser can confirm what is relevant before you share anything.
- What to redact: – you may choose to cover up parts that are unrelated to housing.
- How to store them: – keeping this folder separate makes it easier to share property evidence without automatically including sensitive health material.
If you tell your landlord, agent, or housing provider about vulnerabilities (for example, a child with asthma sleeping in the affected room), note the date and how you reported it in your main log. This shows that you highlighted risk, but it does not replace the need for clear evidence of the damp itself and the steps taken to address it.
Logging contact, repairs, and missed visits so notice and delay are clear

Many damp disputes turn not on whether there is a problem, but on who knew what, when, and what they did about it. A short, disciplined record of communications and visits can be more persuasive than long, frustrated messages.
Making “notice” undeniable
Each time you report the issue:
- Save the exact wording of your message in your contact folder.
- Note the date, time, and channel in your log – for example, “email to repairs@… at 09:42”, “online portal form submitted”, “letter sent by recorded post”.
- If you receive an acknowledgement or reference number, copy it into your log.
You do not need to rely on read receipts, which can be turned off or ignored. Written reports with clear timestamps and system references usually carry more weight.
Phone calls and in‑person conversations still matter, as long as you write a short note immediately afterwards. A good pattern is: “Called managing agent, spoke with [name], they said [summary], agreed they would [action] by [approximate date].”
Tracking visits, works, and repeat problems
For every inspection or repair visit, add a line to your log that records:
- The date and time agreed.
- Whether the visit went ahead, was late, or was missed.
- Who attended (if known) and what they looked at.
- What they did or recommended.
- Any follow‑up date promised.
If something is done on site, take “before” and “after” photos from the same positions you already use. If mould or damp patches return, record when this happens and link back to the earlier entry for that room and that work. Over time, this builds a clear picture of repeat failures or short‑lived treatments, which is very difficult to explain away with a single message about lifestyle.
A clear contact and repair history helps everyone, including any later surveyor, to see whether the problem is being addressed in a reasonable way.
You might, for example, have three separate appointments where contractors fail to turn up. If your log shows “no access” emails being sent to you, but your notes and photos prove you were at home with the room cleared each time, that pattern can be crucial when you ask a landlord to move the case to a higher complaints stage or when a third party reviews what has happened.
Getting escalation‑ready: shaping your bundle for landlords, Ombudsman or Environmental Health

You may be able to resolve matters directly with your landlord or agent. If that does not happen, your records become the backbone of any formal complaint or referral. The good news is that the basic ingredients stay the same; you mainly change how you package and present them.
Preparing a landlord or housing provider complaint
Most complaint processes expect you to set out:
- What you reported and when: – drawn from your log.
- How the organisation responded: – acknowledgements, visits, advice, repairs.
- What the situation is now: – whether the damp has improved, stayed the same, or worsened.
- What impact it has had: – loss of use of rooms, costs, and any health concerns.
- What you are asking for: – for example, a full inspection, specific repairs, reconsideration of earlier decisions, or a formal review.
You can often support this with a short bundle containing your one‑page timeline and a limited set of key exhibits, such as a photo series for the worst room, a sample contact chain, and any significant reports or letters.
A typical pattern might be a two‑page letter setting out the history in date order, followed by a handful of labelled attachments. When you can write “see Entry 12 in the log and Photos 07–09” instead of “I have already told you many times”, you keep the tone calm while making it very clear that there has been plenty of notice and time to act.
Involving Environmental Health or other third parties
If you ask a local authority Environmental Health or housing standards team to look at the situation, they will usually want to understand:
- The nature and extent of the damp or mould.
- How long it has persisted.
- What you and the landlord or agent have already tried.
- How it affects living conditions, especially for vulnerable occupants.
- Whether reasonable access for inspections and works has been given.
Your timeline, log, and folders already contain this information; your main task is to present it in a way that is easy to scan. That often means:
- A brief covering note.
- The log or timeline.
- A handful of well‑chosen photos.
- Copies of key messages showing that the landlord has been told and has had time to act.
If you ever commission, or are sent, an independent survey or inspection report, keep it with your other documents and check that the locations and findings match the way you have labelled things. A surveyor or specialist such as Sussex Damp Experts can often align their notes to your exhibit list so that the whole pack reads as one consistent story.
Book your consultation with Sussex Damp Experts today
When you have lived with damp for months, it is easy to doubt whether your records are enough or whether you have been “doing it wrong”. A focused consultation can turn that uncertainty into a clear, practical plan you can act on straight away.
What you gain from a review
You bring your index, log, and a small set of your clearest photos and messages. In return, you can expect:
- An honest view of where your evidence is strong and where small additions would really help.
- A sense of likely causes and risk areas, based on the pattern of your notes and images.
- Suggestions for what to ask your landlord or agent next, using calm, factual language.
Sussex Damp Experts can also help you decide whether you are at the stage where a survey or more detailed diagnostics would add value, or whether better documentation and a clearer request are the next logical steps.
Turning records into action
By this point, you have invested time and energy in keeping records. A good consultation should leave you with:
- A short checklist of any extra photos or log entries that are worth adding.
- One or two draught paragraphs you can adapt for your next email or formal complaint.
- Clarity on what to send, to whom, and in what order, whether that is landlord, agent, council, or another body.
You stay in control. Your records remain your records. The aim is not to inflame the situation, but to give you enough structure and confidence that whoever looks at your complaint can see, in black and white, what has been happening in your home and what needs to happen next.
Frequently Asked Questions
When should you start keeping records once you notice damp or mould?
You should start your damp and mould records on the very first day you spot anything unusual, even if it seems minor. Those first notes, photos and messages give you a clean starting point: when the problem began, how it changed, and who knew about it. That is exactly how housing officers, surveyors and Environmental Health teams think when they assess a case later: what happened, when, and what did you do about it?
If you “wait a few weeks to see what happens”, dates blur, patches spread, and it becomes easier for a landlord, agent or contractor to argue the damage is recent or caused by how you live. Starting your damp proofing records on day one is like taking the first frame in a time‑lapse—you cannot go back and recreate it.
Acting early also protects you if things escalate into HHSRS inspections, fitness‑for‑habitation questions or pre‑purchase damp surveys. A clear time‑line often makes the difference between “it’s probably your lifestyle” and “this looks like a building defect that needs work.”
What should you capture on the first day?
- A short log entry with the date, room, exact spot, and what you saw or smelled.
- Three photos: one wide shot of the wall or ceiling, one mid‑range of the patch, one close‑up with a coin or hand for scale.
- A note of any contact with your landlord, agent or builder, even if it was just a quick message or call.
If you take two minutes on day one, your future self—and any surveyor you bring in—will have a solid foundation instead of guesswork.
How detailed should a damp and mould evidence log be so you actually keep it up?
Your damp and mould evidence log should be simple enough that you will use it on a bad day, but detailed enough that a stranger could follow the story months later. If a single entry takes more than a minute or two, you will start skipping days—and long gaps weaken your position if you ever need an HHSRS inspection, formal complaint or damp survey.
A lean structure works best: date and time, room, what happened, photos taken, who you told, what they said, and the next small step. Think of each line as a status update, not a personal diary. Over time that gives you running damp survey documentation that can support you with landlords, managing agents, surveyors and insurers.
Professionals are used to reading short, factual notes. When a housing officer or lender’s surveyor can scan a month of entries in a minute and see a clear pattern, you look organised and credible—not emotional, vague or reactive.
What does a “just right” damp log look like in practice?
- You can add a new entry in under a minute after taking photos or speaking to your landlord or contractor.
- Most events fit into one or two short sentences per room, even over several months.
- When you scroll through recent entries, you can see how the damp has progressed without rereading long paragraphs.
| Log style | Effort per entry | How it helps you later |
|---|---|---|
| No log | 0 seconds | Easy now, weak position if things escalate |
| Over‑detailed log | 5–10 minutes | Strong detail, high risk you give up |
| “Just right” log | 30–60 seconds | Easy to maintain, strong enough for surveys |
If you design your log so you can update it when you are tired, stressed or busy, you are much more likely to keep it going until the problem is resolved.
How can you capture strong photo and video evidence with only a basic smartphone?
A basic smartphone is more than enough to build clear, trustworthy evidence for damp proofing and mould complaints. You do not need special apps or filters; in fact, using original, unedited photos helps preserve timestamps and colours, which makes them more convincing to surveyors and Environmental Health officers.
Use a simple three‑shot routine every time you record an area: one wide photo to show the whole wall, ceiling or corner; one mid‑range shot to show the main patch; and one close‑up with something for scale, such as a coin or your hand. Good lighting and a steady hand matter more than fancy equipment. Make sure you include skirting boards, window frames, radiators or sockets where possible so a damp surveyor can orient themselves.
When you record video, talk as if you are walking a surveyor around your home: say which room you are in, what the camera is pointing at, how long the problem has been there, and what has changed since your last clip. That spoken context often matters more than perfectly smooth footage.
How do you keep damp and mould images organised for later use?
- Turn off heavy beauty modes or filters so stains, mould growth and salt marks look honest.
- Create a clearly named album on your phone (for example, “Flat – damp and mould evidence”) and drop every relevant photo and clip into it on the day you take it.
- When you have a quiet half hour, copy those images into dated folders on another device so nothing vanishes if your phone is lost or reset.
If you treat your phone as a basic survey tool and keep everything in one place from the start, you make life much easier for yourself, your landlord and any specialist you bring in later.
How can you build a solid paper trail if your landlord mainly uses calls or chat apps?
You can still build a strong, usable paper trail even if most of the real conversations happen on the phone or in messaging apps. The aim is simple: turn quick chats into clear records that show who said what, and when.
After each important call with a landlord, agent, contractor or freeholder, add a short line to your log: date, time, who you spoke to, and the key point agreed or refused. For messaging apps, take screenshots that clearly show names, dates and times, then save them into your damp evidence folder instead of leaving everything buried in a long thread.
For anything that could later be argued about—access for works, cancelled visits, refusing or accepting a proposal—follow up with a brief written note by email or portal message: “Just to confirm our call at 10:15 today, you agreed to…”. That one habit turns a casual conversation into something that can carry weight under the Housing Health and Safety Rating System, landlord repair duties or insurance conditions.
What habits make calls and chats stand up as damp proofing evidence?
- Pair every significant phone call with a dated log entry and a one‑paragraph recap in your own words.
- Regularly export or screenshot key chat threads and save them with filenames that line up with your log dates and rooms.
- If your landlord prefers phone calls, tell them you will send short written summaries “so we both have the same record”—reasonable landlords and agents usually welcome that clarity.
If you treat each important conversation as something a surveyor or adviser might read later, you will naturally start building a paper trail that supports you instead of one that quietly disappears in a chat history.
How can you record health and wellbeing effects from damp without oversharing private details?
You can show that damp and mould are affecting everyday life without handing over your entire medical history. A short impact diary that connects dates, symptoms and rooms is usually enough for an adviser, local authority or landlord to understand the seriousness, especially where asthma, very young children or older relatives are involved.
On any relevant day, note who was affected, what happened, and where in the property it took place, for example: “11 March – child woke coughing at 3am in Bedroom 2 (black mould on external wall).” Over a few weeks this builds a clear pattern that can support action under fitness‑for‑habitation rules, HHSRS guidance or Housing Act duties, without you sharing unrelated conditions.
Keep health‑related notes and any letters in a separate folder from your main damp proofing records. That way you stay in control of what you share and when. If a housing charity, council officer, surveyor or legal adviser becomes involved, you can ask exactly what they need and provide only those pages. Before copying anything, blank out things like NHS numbers or diagnoses that have nothing to do with damp or mould.
How do you stay in control while still building useful health evidence?
- Stick to brief, factual entries that link symptoms, dates and rooms, rather than full medical stories.
- Note when you first told your landlord, agent or housing provider about any vulnerabilities, such as asthma, respiratory conditions or very young children sleeping in affected rooms.
- Before sending health information, ask the recipient which parts are genuinely relevant to your damp or mould case so you do not give away more than you need to.
If you treat your impact diary as a tool you own—not something you automatically hand over—you can protect both your privacy and your position if the situation escalates.
When should you ask a damp specialist like Sussex Damp Experts to review your records?
It is worth asking a specialist such as Sussex Damp Experts to review your records once you have the basics in place and you feel stuck, dismissed or out of your depth. Common trigger points are when mould keeps returning after basic cleaning, when you are repeatedly told it is “just condensation” but your notes and photos suggest rising or penetrating damp, or when you are preparing for a formal complaint, pre‑purchase damp survey or dispute about repairs.
At that stage, a short professional review can turn a pile of photos, chat screenshots and diary entries into a clear plan. A specialist damp proofer used to BS 6576, BS 8102 and Building Regulations Part C can spot patterns that a generic contractor or busy managing agent may have missed, explain whether your records point to condensation, bridging, penetrating damp or something more structural, and help you frame reasonable, specific requests that are hard to ignore.
Sussex Damp Experts work with homeowners, heritage property owners, landlords, letting agents, commercial landlords and local authorities across East Sussex, so they are used to moving between tenant complaints, surveyor expectations and real‑world building behaviour—including older solid‑wall and listed buildings where breathable, heritage‑friendly damp proofing matters.
What should you bring to a specialist records review to get real value?
- Your main log or time‑line, even if it feels rough, showing when damp or mould first appeared and how it has changed.
- A focused set of photos and videos from different dates, plus any important emails, letters or chat screenshots with your landlord, agent, builder or surveyor.
- Your key questions about next steps: for example, whether to push for further investigation, how to prepare for an Environmental Health visit, or which extra monitoring (such as humidity readings or salt tests) would genuinely add value in your specific property.
If you want to approach this like a calm surveyor rather than a stressed tenant, owner or agent, this is the point to let Sussex Damp Experts turn your records into a survey‑grade damp proofing plan—so you can decide what to do next with far more confidence and far less risk of expensive, ineffective work.
