Sort out damp issues in our living room.

Verified Review

Prokil did a good job (only time will tell if the problem is really sorted, but I have no reason to suppose that there will be any issues). They arrived when they said they would. They left the place fairly tidy each time they came although we still had plenty of dust and some carpet spots to clean. The room looked good when they were done - clearly very professional at what they do, although some of the small details of finishing and filling etc weren't perfect. The price was fair and they stuck to the quote.
