Had some bay windows fitted by a local company recommended to me but I have not really been happy with their work up to now. I pulled back some wallpaper they had flattened down with silicone and found half centimetre cracks where the bay meets the house beneath the window. Cannot check outside in the bricks are cracking as the walls are rendered. Im unhappy because you can feel a draught through them and they have obviously tried to conceal them.
Phoned them up and they are coming to have a look, Generally the finishing wasnt great but I thought I might be being picky. Do I need to worry, the bloke on the phone said some cracking was normal and I accept that, but these are big cracks? Just wondering if anyone has any advice
