London's No.1 Woodworm Treatment Specialists

These guys are very good and have worked for me on and off on different projects for fifteen years. We have never had any call backs and the job has always been completed on time.

Excellent service and honest advice, which actually led to reassurance that no work was presently required!

Declan and his team did a full basement tanking for my house in Henley. The work was carried out to a very high standard and Declan was always professional and helpful. The price was competitive. This is a business that clearly wants to do a good job. Fully recommended.

I recently had Crown Preservation come and replace a failed membrane in an underground vault and am happy to say all damp issues have now been well and truly eliminated. The team who carried out the work were not only super professional, but really cared to not make a mess anywhere else in the property (which was very much appreciated) and most importantly they did a really impressive job on the vault.

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.

Job well done with limited fuss!

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.

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.
