Preservation Treatments (Surrey) Ltd was established in 1972 and have years of experience in providing Basement Waterproofing in Barnet. If you are in Barnet 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 BS8102:2009, (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.

    Damp survey, Guildford, Sarah – 21st July 2017
  • ‘Huge thanks to you all for a brilliant service from start to finish. The wall looks better than it has for the last year, even without the re-decorating, yet!’

    Damp-proof Coursing & Specialist Rendering, Morden, Wendi – 25th July 2017
  • ‘Fantastic service. We booked another damp surveyor who visited and gave very big but vague estimates about the work. To get a second opinion, we went to preservation treatments, the service could not have been better. They gave an honest recommendation about the work needed (or not). Great, honest service.’
