Very disappointing. Mis-sold.
We were sold the 'local' and 'high quality' pitch by the salesman, who noted that unlike a national company like Safestyle, they would not rush to finish the job in a day and that the company was based locally in Barton so would not need to rush away to beat motorway traffic. In actual fact, the fitters rushed to finish the job in a day and had to scoot to beat motorway traffic on the way home to Watford. We were also told that they would clean up after themselves, they did not do anything other than pick up their own tools, sheets and any larger debris - the house was a state.
The actual windows and doors are of satisfactory quality, but the installation of them was abysmal. The workmen turned up in an Avis hire van which was a bit unusual. After installation, the front door and back door wouldn't shut - the front one required a flying shoulder barge to shut, the back one had a 5mm gap around the door when locked so the house was absolutely freezing as It was winter. There was major damage to the brick work on the outside of the house, the front door especially which had huge holes in the floor. Old trims were not replaced and screws were hanging out preventing windows shutting correctly. In all, there were a list of 15 issues which I called the company about, to which I was told the job was finished and the fitters would not be coming back. I was able to escalate the issue to sales director level and 8 days later the original fitters came to finish the job off, obviously giving me lots of excuses to why it wasn't done originally. They did not finish the job and we have had 4 visits from other people trying to clear up their mess. 7 months later, we are finally airtight and warm. I’ve also had to redo the silicone around the windows myself as they used cheap stuff that went mouldy and rotted away within a few months. We also found it near on impossible to get anyone to come out - excuses such as 'a high turnover of receptionists' and general blaming of each other was utterly frustrating.
Now everything is complete, the house is warm and the windows are ok. However the experience of going with Kingsbourne was a negative one. Judging by the other reviews, we may be the exception but it doesn't make our sad feeling any better!
