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.
If you're seeing any of these signs, get in touch for an expert damp survey.

What Our Customers Say
Rated 9.84/10 on Checkatrade · 445 reviews. Read what our customers across Sussex have to say about our damp proofing services.
“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.”
“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.”
“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.”
What Our Customers Say on Google
“Brighton Damp Proofers provided a comprehensive report of the damp and mould in a room in my rented property. I highly recommend using their services. They are professional, polite and knowledgeable.”
“Fred came and did a fantastic job assisting me with a penetrating damp issue. The work was carried out swiftly, and the team left the flat clean and tidy upon completion. Highly recommended.”
“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.”
