Damp, mould & leak services in Mayfair
Mayfair's housing stock is dominated by Georgian and early Victorian terraced townhouses, red-brick mansion blocks, and grand stucco-fronted properties, many now subdivided into luxury flats. This concentration of 18th and 19th century construction, combined with deep basements, party walls, and dense urban surroundings, creates persistent vulnerabilities to damp ingress, condensation, and concealed plumbing failures.

Common damp problems in Mayfair homes
Rising and Penetrating Damp in Georgian Townhouses
Many of Mayfair's original Georgian terraces predate modern damp-proof courses entirely. Ground-floor and basement levels along streets such as Brook Street and Bruton Street frequently exhibit rising damp through solid brick walls. Penetrating damp is also common where original lime pointing has been replaced with hard cement mortar, trapping moisture within the masonry and accelerating internal deterioration.
Basement Conversions and Groundwater Ingress
Mayfair has a high concentration of excavated basement extensions beneath Georgian and Victorian townhouses. These sub-ground spaces are particularly susceptible to hydrostatic pressure and groundwater ingress, especially given the area's proximity to historical watercourses and dense surrounding development. Inadequate or ageing tanking systems in properties around Shepherd Market and Carlos Place frequently fail, resulting in persistent wet walls and mould growth.
Hidden Leaks Within Converted Mansion Blocks
The large Edwardian and interwar mansion blocks found along Park Lane and near Grosvenor Square were not originally designed for the volume of internal plumbing now present following decades of flat conversions. Shared riser pipes, outdated lead pipework, and poorly sealed service ducts allow slow leaks to track between floors undetected for extended periods, causing concealed timber decay, ceiling staining, and significant mould colonisation within wall cavities.
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.
