Services

London Waterproofing Solutions Ltd are cellar conversion and waterproofing specialists covering London and the Home Counties.

The recent bad weather and severe flooding in many parts of the UK have identified some severe problem with the efficacy of the water protection measures in many properties. When it comes to penetration of ground water, then this is a much more difficult problem to deal with and requires specialist help.

At London Waterproofing Solutions we have the skills and expertise in the control of dampness and ground water ingress. As a family business, we use our own highly skilled, CSSW qualified surveyors, and fully trained technicians. We are not general builders and work only in our specialised field so you can be assured of a personal and professional service.

Basement Waterproofing Tailored to Your Requirements

Many thousands of properties in the UK have unused potential in the form of cellars and underground storage spaces. More recently the unusually heavy rainfall has caused flooding basements in several areas across London. If you have a large basement area you want to turn into additional living space, or a small coal vault or cellar to be used as additional storage, we can help.

Waterproofing of any below ground structure must comply with the requirements of BS8102:2009 (The code of practice for the protection of below ground structures from water from the ground). This code of practice makes clear the requirements for waterproofing design and installation as well as the types of system and products that can be used.

All our work carries a 10 year guarantee, which can be underwritten with an independent insurer (GPI) giving additional peace of mind. All guarantees are transferable in the event of a sale of the property.

During our survey we will discuss your requirements, how you will be using the space and assess the construction. Once this is done, we will send a detailed report and quotation for the installation. Our surveys are free of charge, so why not give us a call on 020 7458 4655 and see how we can help.

Architects & Developers

When BS8102 was revised in 2009, one of the key additions was the requirement for a CSSW qualified surveyor to be involved with the design team to advise on the waterproofing for any basement construction.

Along with BS8102 there are often additional requirements from warranty providers regarding waterproofing. Some, such as NHBC, require two methods of waterproofing to be installed. This is often in the form of waterproof concrete construction (Type B) as well as an internal cavity drain system (Type C).

Whether you are constructing a new property, or renovating an old one, we can assist you in the design and installation process. Contact us now on 020 7458 4655 to discuss your requirements with one of our surveyors.

Customer Testimonials

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!)."

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!"

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.

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."

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."

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."
