What our customers say

We are very pleased with our frameless curtains in our dining room and lounge, both of which open out into a conservatory.   Our first contact with you, by telephone, was excellent.  We were invited to look at your glass curtains at your showroom in Chatham which is an hour and a half distant.  Seeing the glass curtains was the best thing to do for us.  Even though your web site clearly shows them, we

I like to confirm that the performance on site was excellent and the lads where very polite and helpful. The doors look great, all we have to do is to undertake all the finishes around the framework.

We chose FGC because we wanted something unique to connect both garden and our new room.

Local suppliers weren’t much help, however the Google came up with just what we wanted – frameless glass doors. We contacted Gary for a price. He arranged to come and do a survey the following week – 600 mile round trip – arrived on time.

Somewhat belatedly may I thank your team for your no quibble, courtesy and efficiency in fixing the problem with my door. All down here are most impressed! Thank you for your input into all this. MBH,

I just wanted to say that I remain hugely impressed by your level of service. The two chaps who came out to service our doors were once again marvellous.  They are very polite and clearly very skilled. It’s very easy these days to complain and sometimes it’s nice to pass on credit where it is due. Please thank your team. Kind regards

I would like to reiterate that we are very pleased with our new FGC doors.
