Hi all! We recently had 9 upvc windows replaced aluminium, 7 of them with acoustic glazing 8.8mm/6mm (two bay windows and a bedroom all leading to front of the house). We raised a complaint with the company on the last day of the installation as the new windows were noisier than previous old windows and had prepared a list of complaints too. Here we posted pictures we've collected from during the installation We think the property was not correctly surveyed.. From GGF installations manual it says to remove architrave to assess the opening and take appropriate measurements where sash-box or check-reveals were found. The surveyor never did this. The surveyor also said the woodwork around the windows were of a nice construction and that they only needed to trim 10mm to fit new frames, which we've agreed but expected for the installers to remove them to make the cut and because they didn't more than 10mm were cut. The company is only going to do these remedial work: -Re-fit the bathroom window (as one of the packers has not been installed) -Rear bedroom window to be de glazed and the visible silver tape to be removed and then re-glazed -Fill all of the external bay windows where some of the mortar has been dislodged removing the old windows then re-seal and clean -Fit a colour matched upvc trim around the inner bay windows for a more aesthetic finish over the black silicone (which we don't agree and they only try to cover a bad job) What's your opinion on this? We're now going to write to GGF & Fensa and see if they can help.
