Complete disappointment in the installed windows and unprofessional service: We have just had three windows installed by Alpine Aluminium and they are badly installed damaged and unfinished. Although the broken glass will be replaced, there are a number of major issues with the windows. One of the windows is too small for the opening and they have added a plastic cover over the gap which looks unsightly. There is a massive gap on the inside. In this window, the openable panel is misaligned within its own frame. This window needs to be replaced. Other defects in the installation are: - some of the window frames are damaged but were still installed anyway, - the mastic sealant has been done really badly. - end caps to cills are missing - the inside junction of the windows is a complete mess. Despite the above, the rude installation team wanted our contractor on site to sign off the works! He was really pushy and rude. We were asked to pay most of the cost upfront and now we are really worried, especially since they are very slow at responding and after reading the reviews on this website. Once we paid the deposit, the team completely ignored our queries. After calls and emails were unanswered, we made complaints to the logistics manager, Andrew, who we were dealing with, no one was able to tell me who I can complain to. he eventually replied without acknowledging our complaint and without an apology. After this we were ignored again and this time we were told that the main manager who would deal with issues is Carol, who we then wrote to but did not get aresponse either. The whole process has been extremely frustrating and the windows are really expensive for the low quality of service and product! We were told that it will take 72 hours for someone to come back to us. It is incredible that with such low quality installation, they want to wait 3 days before they come back to their disappointed customers.
