A few months ago Anti-Damp installed modern vents in the underfloor section of my 100 year-old Lilyfield house. Within weeks I noticed that the wooden and carpeted floors felt less damp under bare feet. And I love the look of the new vents! If only I had done this years ago (would have saved my walls from damp damage too). I guess I hesitated because I didn't know who to contact. But then I found Barry, who immediately impressed with me with his knowledge and honesty. I will definitely contact Anti-Damp again for other properties and for other services.
