Report
Recently had Topline replace two large windows in my sons flat and a replacement conservatory in our house along with new back door and double patio doors. Very pleased with the work completed - Ray and Lewis worked hard, were extremely polite, helpful and did a great job. Also electricians and plasterers were polite, punctual and completed a good job. Very happy with our new conservatory with a lantern roof. Thank you.

What a waste of time. Phoned on the Monday to arrange someone to come out to take measurements for a replacement set of doors. Earliest they could come out was Friday. Guy turned up, looked at the damaged door, and then left to see what hinges he had in stock for the door, even though we told him that the door needed replacing and it had a crack in it. He left and have not heard a thing. I spoke to the office, who said they would get him to call me. Heard nothing. I have now wasted a week waiting for this company to give me a quote, when I could have had someone else come out instead.

Recently brought a house that has had windows fitted by this company... Previous owners gave us all receipts and guarantees as they have 10 years on them
Noticed a problem with one of the windows and didn't even get as far as complaining about door lock.... so emailed and they have said it's not on the windows it's on the person who paid for the windows.... In one bit of the guarantee is states that it's not transferable but notice of transfer can be requested for a sum to be paid at the discretion of the company.... They have now said they will do that at a charge of 300!!!! Absolutely ridiculous
