We asked Kettell windows to quote us for a large bifold, front door and 4 windows. Along with other quotes, Kettel were very reasonably priced. Upon work starting the job was done efficiently, professionally and to a very high standard. The fitters kept the site clean and tidy. The finished job is amazing and we couldn't be happier. We just need to get the window key for of of the windows (the only thing that was missed) Absolutely fantastic job.
