If the rest of their Installation crews are as professional in the work as the 2 guys I had. Then I would recommend Crystal Windows time and time again. From Start to finish great care was taken in the fitment of our French doors. Constantly measuring and checking everything fitted perfectly. Looking forward for the installation of the rest of my windows. Funds permitting. Well done.

Sam and Paul were our fitters. They were brilliant. Everything was done cleanly. They were always on time, polite and helpful. Everything went smoothly and the windows and doors look amazing.
Really impressed with Crystal from start to finish.
I am delighted with my new BiFold doors which were installed by a very experienced and competent pair of fitters.
