Timber decay within buildings of any age is often caused by rot. Wood rot can show up in two prevalent forms: dry rot and wet rot, both resulting from fungal decay suffered by building timbers.
Wet rot is a type of parasite which grows in wet timber. It alters the structure of the timber, causing swelling and separating its fibres, which leads to crumbling and loss of strength in the structure. Wet rot causes wood decay and loss of structural integrity, making the timber disintegrate. Wet Rot is caused by structural wood coming into contact with sources of moisture. It could be from faulty plumbing or penetrating damp, on the ‘wet’ side of the house. Wet rot is a fungus, it will spread to timbers in the vicinity of the source and cause damage.
Dry rot can inflict damage faster and trigger extensive decay to structural timber as it consumes and spreads throughout the affected property. Meanwhile wet rot, despite being a more common occurrence, causes less damage; decay is typically restricted to the areas that remain wet on the timber. It is possible to differentiate between dry and wet rot by associating the extent of damage as well as the colour of the timber with the development of either type of rot.

Wet rot is a serious problem. It can cause irreparable damage to your home and reduce its value. Wet rot in the home must be addressed immediately, otherwise, you run the risk of it spreading and infecting the rest of your home. A survey of 2,038 London property owners inquired whether they had experience with wet rot in their homes, where the problem was identified, and how effective they were at preventing future cases.
The results were appalling – over 20% of the respondents had noticed wet rot in some form or the other. Wet rot can attack timber flooring; making the property lose its structural integrity. Apart from the costly repair work, it could go even further by devaluing your property. Most insurance providers will not offer policies to buildings with clear signs of moisture ingress or damp buildup.
The signs of wet rot or the conditions that allow the fungus to gain a foothold in the timber depend on the type of moisture it comes in contact with. Peeling wallpaper (especially at the corners), malfunctioning central heating boiler, a persistent musty smell, and malfunctioning cookers are some easy-to-spot signs of wet rot. Some common locations for wet rot include underneath the kitchen sink, roof spaces/attics, and along external walls. Wet rot typically attacks older buildings constructed using timber frames rather than modern species such as Meranti and Sapele. Timber from below ground level up to a one-floor level is another prime victim of wet rot. Being able to identify wet or dry rot is a big part of managing its growth. If you notice any signs of wet rot infestation, then you should carry out a damp survey as soon as possible.
It should be an annual task, similar to spring cleaning to search your home for signs of damp or wood rot, and a good time to do it is during your pre-winter weatherproofing activities. You’ll need a screwdriver with a long handle and a decent flashlight.
If your building has one, check the siding below and around the windows for any sign of swelling or discolouration in the wood. Paint can cover wood rot, so the wood must be rough and solid, try jabbing the siding with your screwdriver. If you notice that the wood feels spongy and the surface gives in to pressure, then you have wood rot. Use a decent flashlight to inspect the attic for discoloured wood. Transition to the screwdriver test if you notice any. Ensure you check the underside of the roof decking, in the joints where the wood members connect at the top of the roof, and at the edges of the attic where the rafters slope down to form the eaves, are prime spots in the attic for wood rot.
With the flashlight search for discolouration around the border wood plate that sits on top of your concrete basement wall, scrutinize the wood members. Inspect any discoloured areas using the screwdriver. Check the walls and floors to spot discolouration below sinks and catch water leakage around baths/tubs and the water heater.
Recognising wet rot is not always a straightforward or easy task, wet rot is versatile and attacks timber in several forms. Pushing a knife up to the handle into painted timber is an effective way to confirm rot. Our damp-proofing specialists have tons of experience and training to detect the following:

Wet rot can be found predominantly in areas that are constantly exposed to moisture. Nevertheless, during treatment we don’t just get rid of the wet rot, we tackle the issue at its source. We eliminate the possibility of facing similar issues by identifying exactly how the moisture reaches the timber and blocking off all the access points.

The same with other property-related repairs, the longer you wait, the worse it gets. If you recognise the presence of wet rot early enough, the treatment can be restricted to a small area. In circumstances where the wet rot has been allowed to take deep root in the timber, you might have to consider replacing entire timbers or carrying out major repairs. Treating wet rot involves a series of steps. The wet rot treatment should start by attacking the problem at the root; protecting the timber from contact with moisture. If there is a seepage of water into your home or timber, regardless of whether the cause is broken guttering, condensation, or anything else, we locate the source of water/moisture ingress and take corrective action. Replacing the affected wood is often the port of call for inexperienced builders or contractors. Using chemical preservatives on the damaged area is usually the next step. Such an approach is assured of failure. If you are unsure about the presence of wet rot in your building, no worries! Sussex Damp Experts is always ready to help you get rid of it and save your timber.
Leaving wet rot to grow unchecked will lead to the weakening of the structural timber which could affect the safety of the residents. When the rot settles in the timber, it becomes spongy and falls in if you poke it with a knife or screwdriver. The ultimate result is a loss of structural integrity and even possibly your building being condemned. Call Sussex Damp Experts 01273 257877 and discuss your project with one of our wet rot treatment experts today.
Rot can have a devastating effect on any property. The cost of damp proofing and remedial works varies depending on the type and severity of the problem, but you shouldn’t let that put you off. With our team of experts on hand to help, you’ll quickly discover that with wet rot treatment in East-Grinstead, it is more affordable than you would expect. We advise you on the best course of action to protect your home and your health.
Wood should be protected from moisture at all times to prevent decay. Wood hardeners for use on timber at risk of being affected by wet rot are also an effective measure. The wood gains strength after the hardener soaks into it. The areas in a building that are most susceptible to damp include window sills and boxes, timbers touching stonework without being subjected to damp proofing treatment such as sealant and fungicide applications.
