London's No.1 Condensation Treatment Specialists

Declan took the call on holiday and gave logical advice to resolve our commercial damp issue. Will be speaking to again

Declan came round to survey a damp problem, gave a narrow time slot and quickly assessed our problem. Suggested a solution and put me in touch with a roofer who has so far been decent. He didn’t quote for internal repair work as suggested we let it dry out first and/or repair with a decorator. Basically quick, experienced and honest. Decent

A very honest opinion of our damp problem and no sales hassle. In fact the recommendation was to get to the root of the problem – a leaking flat roof – before Crown Preservation could assist

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

Great service, friendly and professional. Really happy with the standard of workmanship.

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.

Great job from the team. Very helpful in their advice and fitted our job in very quickly. Thanks

Declan knows what he is doing! Gave us his expert opinion and clear advice saving us £££. Thank you very much.
