What our customers say

Highly recommended

From the first moment of making contact we were given a very personal and friendly service. The survey, fitting and installation were all carried out by helpful and pleasant people. Follow up service was equally good. I am extremely pleased with the results.

The best doors ever!!

We have had our corner installation for about 2 years now and they are the biggest wow factor of the house (the view’s not too bad either😊). The summer is great with truly indoor/outdoor living. The biggest surprise has been the amazing aftercare we’ve received from FGC. They are so patient as it’s often a

The design was complex and required a flexible and innovative approach to their existing designs.

Brilliant After Installation Service

Our FGC sliding doors were installed in May 2018.
Although we have had two relatively minor problems – neither of which stopped the doors from working – FGC have attended very promptly to carry out remedial action.
Excellent customer service from head office and excellent service from install technicians.
