London's No.1 Basement Waterproofing Specialists

Job well done with limited fuss!

We had the Crown team come round this morning and having had a level 3 homebuyers survey on our property when trying to sell it scare us with the level of damp in our property, the Crown team really put my mind at rest and made me feel so much better about the situation. They were reassuring and have said our problems are easy to solve and they are happy to put a guarantee against it! I’m very pleased with the outcome. Thank you! Mia

The team at Crown Preservation completed a considerable area of damp proofing to our basement flat, after Declan’s initial inspection. It’s clear he knows what he’s talking about, and the quality of work was really high.

Declan has always been available and responsive. Although it was only a relatively small job compared to some of the other jobs he undertakes, he approached it with equal importance and care. The work was completed on time and to a high quality. He was prompt with any follow ups and was available when we called with any queries. We would have no hesitation recommending him.

Able to programme the job at short notice and work completed with no fuss with a 30 year Insurance backed guarantee. Happy to recommend.

I can not fault Crown Preservation and the entire team. Some reviews seem ridiculous and fake to me. The job the CP are doing currently is incredible. Well timed. Constant communication and they go above and beyond!

I would highly recommend Declan and Crown Preservation. They were incredibly helpful, highly professional and completed the job in the timelines provided to a high standard and to the price agreed. Declan was always able to answer my questions and provide guidance which was exceptionally useful as this was the first time I have needed to get damp proofing done and he made the process very easy. Thank you!

Declan was extremely helpful and professional when he came round to check for damp in our flat. His advice was very honest and he left a really positive impression.
