Last September I had my front (flat window, aluminium..prob 20+ years old) replaced with a uPVC bow window, which is support by one gallows bracket. The gallows bracket and windowboard are hardwood.
Since the dry weather over the past 6-8 weeks there have been some very loud banging noises coming from the window, similar to wood expanding/contracting, but nevertheless loud enough to make me damn well jump every time it happens. Seems to happen quite a few times during the day.
Noticed one long crack under the window board from the inside about 2-3mm high. I can see daylight through it. They have used a clearmastic on the outside between the brickwork and underneath of window board and some regular caulk on the inside.
Question - is this normal? Should the window-board have been bedded on sand/cement mix on top of cavity wall?
Fitter has been back, says they will put right the crack but assures me there isn't a problem. Unfortunately I wasn't there to throw 20 questions at him.
Any thoughts? Advice?
