Damp, mould & leak services in Seven Sisters
Seven Sisters is dominated by Victorian and Edwardian terraces long ago split into flats, alongside 1930s conversions and low-rise post-war blocks around Broad Lane and Tottenham Hale. Many properties share ageing soil stacks, converted bathrooms stacked above ground-floor rooms, and flat-roofed rear additions, so a single failed joint or perished seal often tracks silently through several floors before staining ever appears.

Common leaks in Seven Sisters homes
Converted flats with stacked bathrooms
Seven Sisters's terraces were subdivided decades ago, leaving bathrooms directly above kitchens or living rooms in flats that share a single freeholder's pipework. A leaking shower tray or failed silicone seal on an upper floor can seep between joists unnoticed, showing up as a ceiling stain in the flat below long after the water has soaked into timber and plaster.
Flat roof extensions to kitchens and bathrooms
Rear kitchen and bathroom extensions with flat felt or GRP roofs are common across Tottenham and West Green terraces. Once the roofing membrane ages or blisters, water tracks along joists rather than dripping straight through, so damp patches often appear well away from the actual defect, delaying discovery until timber and insulation are already saturated.
Ageing plumbing in multi-occupancy buildings
Many Seven Sisters properties near Bruce Grove and St Ann's were converted into flats with plumbing runs added piecemeal over the years, mixing old lead or copper pipework with newer push-fit fittings. Hidden joints behind boxing or under floorboards can fail gradually, and because several households share risers, tracing the source of a leak often requires checking more than one flat.
What our customers say
Very appreciative of the service and their follow-ups
Excellent service from Damp & Mould Solutions. Kerim was my main point of contact throughout and was professional, knowledgeable and extremely helpful from start to finish. Communication was clear, everything was explained properly, and the work was handled efficiently and to a high standard. It’s refreshing to deal with a company that does what it says it will do and keeps you informed along the way. I’d happily recommend Damp & Mould Solutions to anyone dealing with damp or mould issues. Particular thanks to Kerim for making the whole process straightforward.
Friendly, approachable and most importantly professional. Great service!!
spoke with Karim who was incredibly knowledgable and helpful. He provided me with very useful information and went out of his way to help me. He also answered all my questions thoroughly. They were very fast to respond via email and wotsapp
Clearly communication, easy to deal with and responsive. We would thoroughly recommend. The report was really detailed making our buying negotiations a lot stronger and leaving us with a clear plan of action with possible timeframes.
Was lovely working with the team and they did a fantastic and quick job to get all the mould out of my bathroom. Very much looking forward to working with them on other projects around my house!! Thank you for everything and shout out to Karim for being so sweet!
Top notch customer service from Kerim! He fully explained the process properly so we knew the ins and outs of the cost and the plan of action. The survey was done, they treated the mould and followed it up with a dehumidifier session and that's it no more mould, no more dampness and best of all no over complicated jargon and inflated prices. I left it a month before leaving this review to see if the mould would come back and I have had zero issues. I would highly recommend Damp & Mould Solutions UK.
Omg what brilliant service, excellent the cleaner did a very good job was efficient he took his time and cleaned everything, highly recommend S. Bessim…
Fast and efficient service
Highly recommend this company, very professional but kind service provided.
Very positive experience. From the first call every detail of the process was explained clearly which put me at ease. Kerim shared knowledge of what I should expect from the survey, and what to expect from the treatment so I could plan my day accordingly. I was provided a quote the same day which was the most competitive of all the quotes I received. Easy to book, friendly to talk with and completely took away all my stress. If you're dealing with mould and in a similar situation as I was, these guys are definitely worth the call.
Kerim and his team were amazing! Firstly, they surveyed my home and the report they provided was very detailed and found the cause to be a leak from the bathroom. As it was an active leak we were quoted the same day and had his team over the next day to fix the leak. Once the leak was fixed they returned the following week to install drying units and treat the mould. They returned 2 weeks later to collect their machines and provided us with a certificate of dryness which proved it was all dry and fixed. All in all the whole process was efficient and I couldn't fault their service in the slightest. Within a month our home is back to feeling clean and stress free. We are glad to have found someone we can trust and we will definitely keep your number saved and we will be recommending you to all of our friends and family.
Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.
We used Damp & Mould Solutions to check whether damp in our living room and bedroom was being caused by structural issues with our leasehold block or simply poor insulation/ventilation. The service was very impressive, with our surveyor David explaining the issues and best solutions clearly to my partner and I. The final report produced was professional and reassuring, meaning we don’t have to take a case to the council. Overall, fantastic service and would certainly use again!
Great experience with this company from start to finish. They were professional, knowledgeable, and explained everything clearly without any pressure. The work was carried out efficiently and to a high standard, and we’ve already noticed a big improvement. It’s reassuring to deal with a team that genuinely cares about doing the job properly. Highly recommend to anyone dealing with damp or mould issues.
Very professional and organised I must say came out and completed the work very efficiently customer service was excellent. Definitely recommend this damp and mould service to anyone looking for a job done correctly. :)
I have been dealing with damp and mould for years but these guys were able to come in and resolve the problem quickly and professionally. Their prices were fair and reasonable and they got the job done clean. 10/10 would use again and would recommend.
Used Damp & Mould Solutions UK for a damp and mould issue at my property in South London. Really professional service, fast response and very knowledgeable. They use specialist equipment including thermal imaging which gave us a clear diagnosis. Would highly recommend to anyone dealing with damp, mould or a hidden leak.
Very helpful and professional, easy to communicate with about my mould issues and I received fast responses from the company on the best solutions for me. would recommend to all friends and family. 5/5
I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.
