Wet & Dry Rot Control

As one of London’s most established and reliable damp proofing companies, our expert engineers at Quadrant Damp & Timber Treatments carry out wet and dry control treatments for both domestic and commercial properties.

As the two most common forms of fungal decay, if left unaddressed wet and dry rot can escalate into major structural damage.

Our expert surveyors and engineers guarantee a quick diagnosis followed by thorough wet and dry rot treatment for properties throughout North and West London, including the Ealing and Hampstead areas. A damp survey is a crucial part of dealing with the problem, and in certain cases the use of specialised epoxy resins can be carried out to reinforce large structural timbers.

All of the insecticides and fungicides we use have passed stringent British Health and Safety Executive (HSE) tests, and have a one hour period before people without protective clothing and equipment can re-enter the area. To find out more, or to arrange a survey, don’t hesitate to contact our team of specialists today.

We used Quadrant for damp proofing the ground floor of our home. We found them to work diligently in getting the job done. All questions and concerns were addressed by the team. I wish to express a special "thank you" to Ellie, Paul and Rob. I can also say that both Rob and Paul cleaned up after the job and Ellie always provided a polite, professional and proficient service. I recommend Quadrant to anyone looking for damp treatment. Thank youread more

Very helpful, a professional report was done, the guy who came to see my property was on time and polite. He sent me a very detailed report explaining that the problem was condensation not damp, and how we can prevent this in the future. I contacted many other companies, some wanted to charge me for a survey, some didn't turn up and one was rude to me down the phone. I can't stress enough how pleased i was with this company's attitude, I would recommend them to anyone.read more
