Highlights
"We had a leak in our cellar needing tanking. Armond and his team were brilliant from start to finish — very efficient in terms of providing a fast quote, fair price, and a really responsive team who took great care of the house during a messy job. Highly recommend."
"The team undertook extensive damp proofing work in a basement flat. They were punctual, hard-working and cleaned up effectively at the end. The director was very responsive and flexible - when more work came to light than expected he attended the site several times and fitted the extra work in around existing commitments."
"City Waterproofing treated rising damp in one of my bedrooms. The work was very fairly priced and carried out very professionally to very high standards. The quality of workmanship is excellent. The room was thoroughly protected from dust and debris during the works and cleaned up afterwords and left tidier than before they came. I am very happy."

Armond and his team did a great job of waterproofing my cellar. They were very polite and respectful of my property, turned up when they said they would and did the job quickly and accurately. Probably the best experience I’ve had with a team of builders.

I used City Waterproofing Ltd for a complex basement project, including rising damp repair on a ground floor interior wall and a new French drain for my patio. Armond runs an incredibly tight ship; his technical assessment was honest and gave me total confidence. The onsite work led by Gerti and his team was exceptional. They were punctual, respectful, and kept the site pristine despite the complex nature of the job. The project started on time and was completed in just 6 days. Highly recommended for specialist waterproofing.
I had rising damp along a section of the kitchen wall. I called City Waterproofing and Armond came round the next evening (after a long day's work). A detailed quote outlining the work arrived promptly + a day for the works. The guys worked really hard and efficiently, they covered literally everything in the kitchen and left the wall replastered and absolutely immaculate, they removed all the covering and washed the floor and hallway, They were so polite, friendly and discreet. Excellent value for money, I would highly recommend this company to anyone with damp issues.
I was very happy the first time City Waterproofing did some work for me and was equally pleased the second time. The work was completed on time and to a high standard. The team also took care to minimise dust getting around my house and cleaned up both inside and outside when the work was done.
Armond and his team were brilliant from start to finish. We had severe damp in our lower ground floor bathroom, so needed tanking. They worked incredibly hard, were very reliable, friendly and professional. Clear communication throughout and Armond helped bring in a plumber, electrician, and painter to totally refit and decorate the bathroom. Helped us get it all done before Christmas too! Very fair price too. Beyond happy with the result and highly recommend! Thanks Armond and team for doing such a top job.
I had rising damp issues in my flat and for a long time could not solve these. Armand and his team managed to do a great job and later I hired his painter Disi to take care of decorating my flat - and it looks now better than when I first got it! He did a fantastic job, five stars. I highly recommend this company, they are fast, efficient and left my flat clean and looking brand-new. Thank you guys!
From start to finish Armond, Gerti and the guys were great. Even with a a couple big setbacks they never stopped and got the job done as quickly as possible. They were really easy to deal with and vey pleseant to have around, they were very fair on price and i couldnt recommended them anymore.
City Waterproofing inspected. Our property and have a clear written report to us on works that were required. A clear price was quoted. The works were carried out on time and extremely well with the property left in excellent condition and beautifully plastered walls. They are an excellent company and I can’t recommend them highly enough- Julian K
Excellent service. Great communication & ideas to choose from. Quite was very fair & exactly what we paid. Highly recommended
From the initial visit to completion the company performed to the highest standard. Their quote was the lowest and quickest to arrive. They flagged from the outset the possibility of additional work being needed for the repair. That prediction was accurate and the extra work was arranged quickly and at reasonable cost. The overall quality and value for money were excellent
I was very happy with the work Armond and his team carried out. They executed it quickly and to a high standard, at what I felt was a fair price. They also cleaned up all of the dust and mess that was created by the work and took all of their waste away. I would happily employ City Waterproofing again if I need more waterproofing work.
All tanking works were completed on time and on budget. No issues with Contractor. Good alignment with other contractors on site. Professional and courteous. Recommend.
City waterproofing were really great. We needed our plaster removed and replaced and they quoted me an extremely reasonable price (unlike most of the other companies I got quotes from). They injected damp prevention and put up a waterproof membrane before replastering. Particular highlights were how responsive they were on WhatsApp to help and the two guys who came to do the work (Gerti and Dorian) were very nice, efficient and supportive throughout. Completed to a high standard. Would highly recommend!
I had a number of quotes from other companies to retank a basement where there were water table problems. I am very pleased we decided on City Waterproofing. Armond and his men were punctual, polite pleasant to have around and very hardworking. There was an almost immediate response to any telephone or email queries. All the crew who worked here had appropriate skill levels. I would and will recommend them
Fast, neat and tidy work. Cleaned up well after the works so that disruption was kept to a minimum.
All looks good. Armond was helpful and explained everything in detail prior to starting the job and gave a reasonable quote. The work was carried out on time and the men left everything very clean and tidy. I was kept informed throughout of any problems and everything seems to have gone to plan.
Armond and his team were always, polite, punctual and clean. Everything was explained to us calmly and clearly with minimal fuss (despite extent of damage to walls). They delivered as promised and were honestly priced.
