Preservation Treatments Limited was established in 1972 and have years of experience in providing Basement Waterproofing in London. If you are in London and are considering a basement conversion or require any structural waterproofing then call us on 0800 1422 513 to arrange a survey.

We are contractors for all the major suppliers, including Delta, Natural Cement, Safeguard (Vandex and Oldroyd), Wykamol and Sika. We can help to transform your cellar or basement from a damp, musty dead space into a beautiful addition to your home or office, adding value to your property.

Waterproofing underground structures, such as basements & cellars, is becoming more popular as moving may not be affordable or convenient. Converting a damp basement or cellar can be a surprisingly inexpensive way of increasing the living or storage space of the property.

Our CSSW trained Surveyors (Certified Surveyor in Structural Waterproofing) will assist in designing an effective structural waterproofing system to the guidelines contained within BS8102:2022, (the code of practice for the protection of below ground structures against water from the ground).

We believe our depth and range of knowledge coupled with our dedication to providing high levels of customer service are the cornerstones of our continued success. As a result of this dedication many of our earliest clients continue to consult us.

Testimonials

Good afternoon. I would like to thank your company for excellent service and in particular your renderer/plasterer Marlon. He left the area very clean at the end of each day and the finish he achieved on the walls was exceptional. He took great pride in his work and was a pleasure to have working in our home. Please pass on our comments and thanks to Marlon for a job well done.

Job Well Done, Aug 2023

Honest company with principles of gold. They’re helping people unlike most companies looking to rob people. I contacted Preservation Treatments for a damp and timber surveyor for a property we’re looking to purchase. Jo and Michelle were so helpful over the phone and so understanding with my situation, they were very knowledgeable and professional. When I sent the pictures of the property I was looking to purchase the Surveyor due to come out emailed and instructed to actually get a building surveyor because from the pictures in their experience he could tell it would require this level of investigation. Some companies will not do this. Some companies will ask for the pictures knowing full well the status of the situation and still go out knowing there’s nothing they can do just so you pay them and they tell you to go elsewhere. This company isn’t like that – they’re only after helping people which is why they’re PCA members. Grateful for their time. Highly recommend!

Damp and Timber Survey, June 2023

I am writing to you because I would like to express how grateful I am for all the help and support that I received from Tony on the 8 December 2022 regarding the condensation in my parents apartment.

The service that he provided was excellent and he is a credit to your company.

Condensation Works, Dec 2022

I would like to say that you have – you, Vince and Dean, all the office people – made this potentially rather chaotic and difficult process as easy and efficient as possible. This has made an enormous difference to us, and we are aware how fortunate we have been. Thank you.

Damp works 2nd December 2021, Mrs L, London

Vince, Matt and Tony – were the best workmen we have ever used – and we’ve used many in several old houses over the past half century; amazingly careful, tidy, efficient and we were never made to feel that our home was “the site”.

Damp Works, Newbury, Berkshire, Mr Walker – 17th November 2020

“Thank you for your report – it was very comprehensive and highly professional. Many thanks again for your excellent service.”

Survey in Fleet, Spencer – 22nd January 2019

Damp-proofing and Specialist Rendering, London, Shelagh – 23rd November 2018

“Ivan has just left, having done a wonderful job in tanking out our vault. It looks beautiful. He was very careful and tidy and considerate in his work, and also extremely pleasant and patient with my questions!”

Waterproofing, London, Elizabeth – 10th October 2018

Just a quick note to thank Alan and David for all their help. I asked a lot of questions and they were very patient explaining.

Waterproofing, South-West London, Siva – 20th August 2018

I would like to pass on my many thanks to your team who have been very professional through the process. In particular, Paul the surveyor was top class. He turned up on time, was very polite & charismatic, and very clearly examined and explained the situation to me for which I was most grateful.

Survey in London, Jack – 22nd June 2018

“Richard was the point of contact I spoke to, he was courteous, informative and outlined the plan of action at the start of each day. They cleaned up very well, I couldn’t fault it.
