What our customers say
Bought some windows and a patio door. Once I moved in I noticed that there was a draught coming in from the bottom, they sent an old man to come and fix it and he didn’t fix it properly. Come the second year the problem got worse. I called imperial windows and they said it’s not covered by the warranty any more. If they would of fix it properly the first time round I wouldn’t have a door bend at the bottom and now may need to get another door fitted as the lock at the bottom doesn’t lock anymore and I can push the door out once locked. Wouldn’t trust this company anymore and wish I never went with them the first time.Customer care is appalling, wouldn’t recommend them at all. If the door would be good quality it wouldn’t have broken within two years or maybe the fitter didn’t do a good job in installationAvoid them!!
Fantastic, professional service, Nick came to measure up and show me styles soon after my enquiry and it was fitted within the short time frame. The fitter did a great job and we are so pleased with it. In fact my neighbour has since placed an order. Would definitely recommend.
Superb service. Nick was great, provided & fitted new front door. We are very pleased. Fitters were great too 😃 Highly recommend their service.
Great experience, patient to assemble brief, attention to detail in design, competitive pricing, excellent fitters - with positive attitude to see through a good job. Happy to recommend Imperial Windows to others.
