Worst installation ever! Plus Steve in the Manchester branch is an absolute fraud! Installation was a night mare from beginning to end. Please refer to the photos. Father and son team did a disastrous job. Absolute cowboys. Cowboys. My old windows were in better condition than my new. Shocking when you think we spent nearly 19k. When I raised this complaint I was told this was the best they could do. After 8weeks of back and forth I was done- I filed a complaint. The regional manager called me the same day and offered me a discount 5% to make the repairs on My property. I took it. Paid the full remaining balance. Conman Steve didn’t even clear the bill/ record the close of sale/ record the discount. now I’m stuck with legal arguing over the remaining 5% balance which should have been written off. Stay away!!! This company is a nightmare!!! I also found out the patio door didn’t fit because the cut the measurements wrong. They did not fix the problems. Just added putty and tried to fob the work off as repaired, save your money and mental well being. You do not need the headache!!!!
