any window fitters around?
I have an issue with damp in my bedroom and want to fit some trickle vents to help stop the problem, i have found varoius websites selling them but is it possible to fit these to pvcu windows that dont have them already? is it a case of drilling a hole and fitting them over the top? Also i am after some pvcu strips about 2 inches wide and about 1cm thick? any advice would be good
