We used a company called www.dampworx.co.UK they came to do our damp proofing went through a water pipe which they never mended properly. Took our money refused to give us a receipt or a certificate for the work. Pipe then burst refused to answer our calls or messages and e.mails sent. Had to call out a plumber to fix it who had to remove some of the damp proof, have tried again and again to get in contact, just completely ignored us. So avoid at all cost and would not recommend this sight at all if I could of given no stars or even minus I would of done. You think your doing the right thing by using this sight and all we got was conned it leaves a bad taste in your mouth for being so gullible.
