London's No.1 Rising Damp Treatment Specialists

Decklan went above and beyond to ensure we felt comfortable with his services and the process we were about to undergo. It was more than a “job” because he wanted us to be knowledgeable in our decisions and ensured safety first and foremost – not just related the job but any concerns we had about damp / leaks throughout the building. Thank you.

Highly recommended. Despite a lot of work load ahead of the holiday break, Declan managed to find a slot for us. The report was very detailed and with all the relevant pictures documented. He was very kind to answer all of our questions over the phone ahead of the release of the report.

Declan and his team were absolutely fantastic from start to finish and I wouldn’t hesitate to recommend them. They managed to fit the project in to coincide with my holiday and the team really went above and beyond to make sure I was 100% satisfied with the end result. Declan was incredibly helpful and a pleasure to work with. A huge thank you from me.

My engagement with this company was extremely positive and a step towards restoring my faith in finding trustworthy people.
The owner of the company Declan is an expert, who is honest and professional. He identified the issues very quickly and incisively; not only was he intent on resolving the dry rot and dampness but showed genuine compassion regarding my scenario. I cannot imagine there are many in London with his level of expertise, experience and concern.

I run a building company, which works in high-end properties in Kensington, Chelsea and Nottinghill. If ever we are asked to attend to any issues concerning damp, I have Crown Preservations carry out the work. Reliable, competent and very knowledgable in their field. I do not hesitate recommending them to any of my clients.

Declan is very knowledgeable and was happy to spend time giving advice on two occasions even when he knew it would not lead to them getting work. Crown will definitely be my first call if I find future damp related problems.

We used Crown for the whole of our basement and cellar. Declan is an expert in his field and knows exactly what to do for all damp issues. He gave great advice on the tanking and damp proofing requirements and helped to save us money where possible.
The work was professional and efficient and the team do a great job of telling you what they are doing at every stage of the process and communicating well.
I couldn’t recommend them highly enough for their work and help.

Declan provided very helpful and informative advice on the work they did on our extension.
