I have just had new windows fitted, all windows apart from one have a gap at the bottom which i'm told by a friend is a drainage path, will the one that is covered up cause any issues? I have attached two photos one with gap and the other is the window where the gap is covered up.
Yes, it may cause problems. Ask why that one has been filled. That part should never be filled. Mr. HandyAndy - Really
And in a short while that trim will be preventing the window from closing properly. Mr. HandyAndy - Really
