Hi Self Builders I need a steer, please I have a new built masonry house, with a cavity and standard DPC window details. I had wet patches low down on the internal reveal - a wet quadrant from junction of window cill and window frame. The builder resolved it with additional mastic around the frame on the outside, and it seems dry now. My questions are - shouldn't the DPC have directed the wet out, before it got to inner leaf? - is mastic in this case a robust solution, or will it need replaced, maybe every 5 years?

Hello. 3 years ago we had 2 new upvc bay windows fitted by an established company in the London area. The ground floor window has sealant between the sill and the brickwork, the first floor window does not. We have damp on the first floor interior wall below the window but not on the ground floor wall below its bay window. There are large gaps between the first floor bay window sill and brickwork and 2 packing strips can be seen from street level on both sides of the bay window. (cant get photos to upload to site). I have several questions and will appreciate any thoughts. 1. Am I correct in thinking that this is how water is getting in? 2. Is it normal to seal gaps under a ground floor window sill but not a first floor sill? 3. Should I ask the installers to come back and seal the gaps? Regards DaveAF

Hi, started our new build around 9 months ago, floors were put in last week but I've noticed the window cills are turning green outside, damp weather ehh?! Can you protect concrete cills from discolouring and algae? Has anyone any tips? Or know and used any products to weather proof concrete cills?
