Excellent service and product from FGC.I have a glass-box conservatory, built with structural glass about 20 years ago. The 2 sliding doors needed replacing, along with 2 side panels, and I contacted dozens of companies selling conservatory doors and none of them were prepared to install their doors because of the perceived risks of working with structural glass.Then I found FGC who, with no fuss at all, carried out a survey, provided a very reasonable quote for the doors/panels and then installed the doors/panels on the agreed date.Communication with the FGC office was always quick and easy. The surveyor and installation team were efficient and courteous. The product works beautifully.We can now use our conservatory again. Thanks FGC.

Fantastic service from start to finish, from the surveying, contact with office to the workmen. I have experience through work of a number of companies providing similar products and these guys have been by far the best to deal with

FGC installed a two-panel frameless glass door at our property yesterday. Wow!! the installation is exactly as discussed, and was carried out by two of FGC's team members who were so professional and courteous. They were excellent, and we have no hesitation in recommending FGC and their team to anyone considering such an installation.We are delighted with the installation, and very pleased we chose FGC.Well done FGC!!

We purchased a beautiful Origin sliding door and side window from FGC. FGC installed the sliding door and window on time, however the sliding door did not fit correctly. Issues can happen. FGC made the process of re-surveying and re-installation very simple. FGC is a very pleasant and professional company to deal with. We are very happy with their service and would strongly recommend them.

Excellent planning and product advice. All the staff were polite courteous and friendly.On the day of the installation, the team arrived bang on time -we live in Wales so a long drive from Kent! They had the job done by lunchtime (fitting a sliding patio door) and I have to say that on first impression of the unit, it looks and feels like solid quality.

We had a 5m stretch of these wonderful doors installed several years ago and have been very happy with the uninterrupted view of the garden that they allow from the living room. They are admired by every tradesman who sees them. A minor problem we experienced with water ingress last year was promptly and effectively resolved, and the doors were serviced for free at the same time.

What our customers say

Unfailingly Helpful

It is a good time to say to you that while we still very much the windows, the ease of opening, the views closed or open, now that the weather has turned colder we have been struck quick dramatically by the improvement in insulation.  The large windows here that you/we have replaced were double glazed

Great product, beautiful & add value to the house

FGC built my frameless porch as per the attached photo. The work was carried on time by their professional fitters. The quality of their work is outstanding. Nothing was overlooked and the final product was

as an Architectural Technologists, I stumbled across FGC and its proved to be my best stumble. I have knocked two rooms into one to make the most of viewing my garden, my wife and I were looking for the most unobtrusive bi fold door frame to maximise the view, which was proving a challenge until

Great post installation service

In addition to the quality of the product – which is stunning, and head an shoulders above anything else on the market – the ongoing support and maintenance is impressive. I had a small issue with the doors recently and their maintenance team came back within 48 hours to resolve everything whilst giving the doors

Delighted with the windows – they make our kitchen so much lighter and are a joy to use.
Two teething problems since installation have been dealt with promptly and efficiently by FGC at no charge.
Definitely recommend them to all.

Porch glass cutains

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 them.

We are pleased with the service, and the quality of finish so far, I look forward to seeing how they look after a few months. My only issues was the timings and delays, but I wouldn’t hesitate to recommend you and indeed have already a few times or use you again. 20150113

Fantastic aftercare service!

I had an installation of 4 doors in December 2018. During the cold snap in January this year the outside glass handle cracked. I contacted Sara in customer support and the handle was replaced free of charge by Liam and Alf who did the job quickly and professionally. They also checked that all the doors

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.

After Sales Customer Service Exceptional

Thank you for your excellent after sales customer service it is exceptional.
The track coating was repaired to a very high standard by Dan the “Magic Man”, he is very professional and his work is very good, to the point that it is difficult to spot where the repair has been made.
