Warning signs

Signs of Damp in Your Home?

Damp rarely fixes itself. The longer you wait, the worse it gets. Look out for these common warning signs.

Peeling Wallpaper or Paint

Moisture behind walls causes wallpaper to bubble and paint to flake, often a first visible sign of rising or penetrating damp.

Musty Smell in Rooms

A persistent damp, musty odour often indicates hidden moisture problems within walls, floors, or cavities.

Black Mould on Walls

Mould thrives in damp conditions and can pose serious health risks, especially for those with respiratory issues.

Damp Patches or Tide Marks

Visible damp staining or horizontal tide marks on walls are classic indicators of rising damp or water ingress.

Crumbling Plaster

Salt deposits from rising moisture attack plaster from behind, causing it to crumble, blow, and fall away from the wall.

Rotting Skirting Boards

Timber in contact with damp masonry absorbs moisture, leading to wet rot, soft spots, and eventual structural decay.

Excellent service from start to finish. The surveyor was thorough and explained everything clearly. The rising damp treatment was completed on time and the replastering looks perfect. Highly recommend Brighton Damp Proofers to anyone with damp issues.

Rising Damp
We had a terrible condensation and mould problem in our Victorian terrace. The team identified the ventilation issues, installed a PIV unit and new extractor fans, and the mould has not returned since. Really knowledgeable and professional throughout.

Condensation And Mould
Had a full damp survey done before purchasing a period property. The report was incredibly detailed and saved us from a very costly mistake — the property had serious dry rot that the vendor's surveyor had missed entirely. Worth every penny.

Brighton Damp Proofers treated woodworm in our roof timbers and replaced two decayed joists in the ground floor. The work was done efficiently with minimal disruption. The 20-year guarantee gives us real peace of mind.

Excellent service. Rob responded straight away to the request for a quote on a house I'm buying. Arriving on time, he was polite and knowledgeable and took the time to explain everything clearly in identifying areas of concern in the flat.

The team were great when we were buying a new house. They did a survey to support us in identifying works and then once we had completed the sale they were quick to get to work on what was an extensive set of damp proofing, wood treatment, improving drainage amongst other things. The team were really professional and efficient, with good quality workmanship and advice along the way. Highly recommended and would definitely use them again.

I have no hesitation in recommending Brighton Damp Proofers for their professionalism and quality service. Rob arrived promptly, at the agreed time, to assess our damp issues, providing a transparent and reasonable quote for the extensive work required. His candid evaluation stood out in that he clearly explained the challenges, including the trial-and-error approach needed to pinpoint certain moisture ingress points, which I appreciated as it set realistic expectations. Scheduling was seamless: Rob worked with me to arrange the disruptive internal work while I was away on holiday, minimising inconvenience. External repairs, though delayed by unpredictable winter weather, were completed without compromise to quality. Throughout, Rob and his team were polite, respectful, and remarkably tidy, thoroughly cleaning up after the inevitably messy process.

Rob assessed my Victorian house for remedial works to rectify damp, a leak, and also other future improvements, explained available options, and discussed in detail the structure of houses like this. He has extensive knowledge and experience and was able to be very specific to problems experienced in older properties. I highly recommend. Thanks so much

A very positive experience- would highly recommend Rob and his team. From beginning to end everything was explained in verbal and backed up in writing. Rob's knowledge and experience is excellent. Every bit of worked described was carried out to a very high standard. The team was very tidy and cleaned up behind themselves, they were also very polite and friendly in all interactions. The plastering finish was also very good.

FAQ

Frequently Asked Questions

Answers to the most common questions about damp proofing, surveys, and our services.

What is damp proofing?
Damp proofing is the treatment and prevention of unwanted moisture in buildings. It covers a range of techniques including chemical damp-proof course injection, waterproofing membranes, render repairs, ventilation improvements, and timber treatment. The specific approach depends on the type of damp — rising, penetrating, or condensation — which is why an accurate diagnosis is always the essential first step.
How do I know if I have a damp problem?
Common signs include damp patches or staining on walls, peeling wallpaper or flaking paint, black mould growth, a persistent musty smell, white salt deposits on brickwork, and soft or crumbling plaster. If you notice any of these, it is worth having a professional survey. Many damp symptoms look similar but have very different causes, and treating the wrong type of damp wastes money and can make things worse.
What is the difference between rising damp, penetrating damp, and condensation?
Rising damp is caused by groundwater being drawn up through walls by capillary action, typically affecting the lower metre of ground-floor walls. Penetrating damp is caused by rainwater entering through defects in the building envelope such as cracked render, failed pointing, or leaking gutters. Condensation occurs when warm, moist indoor air meets cold surfaces, causing water droplets to form — it is the most common type of damp in UK homes. Each requires a different treatment approach.
Do you cover my area?
We cover Brighton, Hove, and the whole of Sussex including Lewes, Worthing, Shoreham, Eastbourne, Haywards Heath, Crawley, Horsham, Chichester, Burgess Hill, Seaford, and Newhaven. If you are unsure whether we cover your location, please give us a call and we will be happy to confirm.
Can I get a damp survey before buying a house?
Absolutely — a pre-purchase damp survey is one of the most common services we provide. Standard homebuyer surveys often miss damp issues or misdiagnose them, which can lead to unexpected repair costs after completion. Our specialist survey uses calibrated moisture meters, salt analysis, and thermal imaging to give you a detailed, accurate picture of any damp problems before you commit to the purchase. Many of our Brighton and Sussex clients use the report to renegotiate the sale price or request repairs from the vendor.
What is the difference between dry rot and wet rot?
Dry rot and wet rot are both forms of fungal timber decay, but they differ significantly in severity. Wet rot requires sustained high moisture levels and only affects timber that is actually damp — once you fix the moisture source, the rot stops. Dry rot is far more serious because the fungus can spread through masonry and affect timber that is not directly wet, making it capable of causing widespread structural damage. Dry rot requires specialist treatment including removing all affected timber, sterilising surrounding masonry, and addressing the original moisture source. If you suspect either type of rot, early professional assessment is essential to prevent escalation.
