A family run business
Crown Damp Proofing Company was established by Philip Valentine and Chris Long in 1979. Over the last four decades, they have grown the company into one of South Wales' most respected damp proofing and timber preservation companies. Successive family generations now work for Crown Damp Proofing ensuring the highest standards of customer service and workmanship.
Our past is your peace of mind
Over the years, we have seen competitors come and go leaving many customers with worthless guarantees and seriously out of pocket due to ineffective treatments and poor workmanship. Unlike most of our competitors, we have been in business for over forty years, which means our conditional guarantees are worth more than the paper they are written on.
