Hi,
Im hoping someone can give me some practical advise to a problem I have just discovered and is really worrying me.
Ive just returned from our Christmas break and went up into the loft to find the black felt was damp in places this was dripping onto the loft board floor and the eaves. Its not penetrated any ceilings, just some of the boxes in the loft are a little damp, just I may have caught the problem in time.
The loft is fully insulated and there was no problem a couple of weeks ago when I last went up. The house is 35 years old.
So the only things that were different in December was that we used our gas fire more up to Christmas, turned the heating down over Christmas (whilst away) then turned it back up on our return.
I've heard of a couple of products called easyvent and lapvent that can help with this problem, has anyone any experience of using them? How much would they cost for a 4 bed detached house?
Also are there any immediate things I can do to reduce the condensation.
Thank you greatly for any advice you can give.
James
