Customer Testimonials

Recommended Trader

"Peter Barber came to give me a quote. I already had a quote from another company for £ 4 500.00. Peter was honest, a true professional, and told me I didn't need any work done to the flat, he didn't find any rising damp, just moisture which he gave me an address where I could find a fan. I feel relieved and I very happy to recommend this trader. It was the best phone call I made in months! Peter saved from stress, loss of money, and having work done in my flat which wouldn't have been needed. A big thank you to Peter."

Valuable Advice

"Peter showed utmost professionalism and integrity on each visit; providing rapid responses and clear explanation of all aspects of the job without a 'hard sell'. He also gave valuable advice on combating our condensation problems and also wrote us an independent surveyors report at no extra cost. His team were early, very tidy and finished the work earlier than anticipated. I asked a number of tradesmen to quote, but service of this level is rare and much appreciated! Whilst I hope I won't be needing their services again, I wouldn't hesitate to recommend London Waterproofing Solutions!"

Major Damp Issue in Basement

"We had a major damp issue in the basement. LWS came almost straight away. They gave fantastic advice and explained all the possible scenarios. They also managed to move another job so we could start the work quicker. The job was completed ahead of schedule and aftercare information is now being shared. Would definitively recommend and use again. (Although hopefully no need!)."

Membrane in a new basement

"We had London waterproofing come and put up the membrane in a new basement we had dug, these guys are the best I have worked with for quality, cost and workmanship. Peter is a great guy to deal with, bending over backwards to make sure the job ran smoothly. I am very impressed with the final product and have no hesitation in getting them to do more work for us in the near future. Peter thanks for a perfect job. Allan site manager"

Basement Flat Damp Issue

"We had a serious damp issue in our basement flat, and London Waterproofing did a great job in fully damp proofing the bedroom and bathroom. I was nervous about the work because of the size of the project, and because we couldn't stay at the flat whilst it was being done, but the company was great to work with. Peter was always on hand for any queries or issues, and when we had a separate problem with a water pipe leak, the team went out of their way to help sort it out. Overall, it was a really positive experience, and I am more than happy to recommend them."

Honest Advice

"Peter Barber came to quote on what I assumed to be rising damp. He spotted immediately that the damp wall was caused by a leaking gutter and downpipe. Sorting this problem out will be so much quicker, easier and cheaper than replacing a damp proof course. Thank you for your honesty."
