What our customers say

We have been amazing our friends and family with our FGC since we had it installed a few weeks ago. Every ‘trade’ that is working on site has been fascinated and suitably impressed with the product and engineering. We are over the moon as it has really been the star of our home extension. Thanks too to the installers who were

Everybody from survey to install knew what they had to do and advised on what needed to be done prior to install. The glass cutains are just what was needed for the porch and have created a talking point within the village. They do look splendid and we are very pleased with

As to how we were from initial contact (were we polite)? Extremely polite & very helpful. Arranging installation (were we on time and on schedule) Excellent, on time & schedule. Were we clean and tidy? Yes. And finally are you pleased with our doors (would you Recommend us)? My next design & build project I will definitely recommend & use you guys. May I also ask if you would like to be on our list

Unit has been replaced thank you, once again I find FGC have responded to a problem with a no quibble replacement, it is good to know that there is still companies left who honour their guarantee in the proper manner and send installation teams that carry out their work in a professional manner with competence and courtesy, I would be quite willing to give any prospective customers a reference if that would be of interest

In my view, the hallmark of something well designed is simplicity combined with good looks… FGC offer this in spades. Having looked at literally hundreds of bi-folding doors, we were struck by how straightforward the FGC product is – and, as far as it is possible to eliminate the frame except around the exterior of the door, they succeed. When you add to that great (and friendly service), and a knowledge of the usage of

Putting a frameless glass walls between our South facing lounge and dining room conservatories was one of the best things we have ever done in our house. When shut, they keep out the cold in winter and, most importantly, the heat on very hot summer days. When open during sunny winter days, the heat warms the whole house and reduces our heating bills significantly. FGC are a marvellous friendly company. Very efficient and a pleasure

How did we advise you on first contact? I was constructing a new extension and FGC were very helpful and understanding of the nature of the project. Updates to the original design (like addition of an extra door) were accomodated easily and efficiently Installation – were the installers polite and did they clean and tidy up afterwards? All polite and as clean as necessary, although given the site was a work in progress with other

I had been looking for some time to replace my patio doors in our lounge as they had very wide plastic frames and wanted something that wouldn’t restrict the view up the garden I asked to see if it was possible to view some already installed close by. Luckily there was, we went and viewed and was very impressed. I’ve seen lots of companies do bi-fold and there is actually one that is on the

I am very happy with the doors – I saw them last night after work – though I didn’t open them as I wanted to make sure I followed the installers’ instructions not to. They look wonderful and my boyfriend and mum tell me they were absolutely lovely chaps. The finish seems brilliant and appears to be a huge improvement on the last installation. Ms Warren, London

We are very pleased with the glass curtains, which do what we want them to – separate the house and conservatory, meeting building regs, but as unobtrusively as possible. We were very happy with the service we received and the efficiency of those who fitted the curtains and we would have no hesitation in recommending both yourselves and the product.
