Hi all. I'm in the process of having some new windows and sills fitted by some local fitters after deciding it was too much to take on myself. Most of the windows are in now but quite a few of them have gaps between the top of the sill and the underside of the window frame. This isn't the drainage gap...this area is fine. Most guides I've seen suggest that the sill should be sealed to the underside of the windows especially at the ends to prevent water finding a path to the wall. The fitters haven't used any sealant between them, but they say this is fine and normal in the trade. The hasn't been attached to the frame by screwing it up from underneath, but by screwing down through the frame into the top of the sill, which clearly hasn't worked very well. They're proposing to put longer screws in to catch the bottom of the sill too and pull it tighter. This doesn't sound right. FENSA seems to suggest that the window and sill should be well sealed together, as does the Eurocell (manufacturer) fitting guide. These guys are CERTASS registered, which I assume have similar standards? What do you all suggest? Is this normal? Or good enough? Will water be able to get to my house? Can they rectify without taking the windows out? The images are from a 1.8m wide window, but there are similar gaps on some 2.4m wide ones and also narrower ones. There are also some windows with 15mm is gaps underneath them which are foam packed, which they intend to back-fill with mortar. Any advice is greatly appreciated.
