Our small job was handled extremely professionally from start to finish and we are very pleased with the results.
Very happy with the service I have received, everything went smoothly no issues, I was kept up to date throughout the process and the fitting team were very professional, polite and friendly I would recommend fgc to anyone thank you
Amazing service, great aftercare, incredible product. It was hard to find something that would fit in our house and would have been pleasing to the eye aswell as stylish and modern and unique.From sales to install was smooth and stress free amazing bunch of people to work with I had a great experience
Great product with diligent, professional staff from start to finish. Highly recommended.
Firstly I have to say a huge thank you to Paul the owner of FGC for being willing to take on the job of sorting out the extremely shoddy and poor installation of the Origin doors and windows fitted on my new build home, when it was built. And replacing the damaged gaskets. I had your guys with me for two days this week. What a breath of fresh air comparted to the people of originally installed my doors and windows. Extremely professional and lovely chaps. They worked tirelessly to sort out the many issues we had. Would absolutely recommend 100% THANK YOU !
Response from the owner: Good Morning Paul, Thank you for taking the time to share your positive experience with us. We are absolutely delighted to receive it and are pleased we were able to resolve the issues for you. It’s been a pleasure working with you. If you have any further need in the future, please do not hesitate to contact us.
Very helpful and good communication, great product. Thank you.
Very happy with doors. Look great. The installation was quick and straightforward.Will recommend
FGC were brilliant. Great advice on the best windows to get. Extremely good installation. Always ready to solve any installation or manufacturing issues. We are extremely happy with the end result!
Frameless windows were brilliant, Liam Alfie and James were great, polite, courteous, and left the site clean and tidy. The windows look amazing, Great service from start to finish. Many Thanks
We love these doors and look forward to having them open a bit more once the patio has ben completed. They really have a "wow" factor and this becomes a double "wow" when people are shown how the corner can be completely opened up. It was about a year from my first enquiry to the doors being installed as there was a considerable amount of building work required to prepare the room. throughout this period I remained in touch with FGC and the service was exceptional. The installation team was on site for a day, starting early and working through to completion before driving back to Kent!! We have been really pleased with the standard of workmanship and even had compliments from other tradesmen working on the room (most of whom had never seen doors like this). These are expensive doors but the price difference from a normal set of bi-folds was well worth it for the uninterrupted view you get. The doors were installed in February but I have held off doing the review until the room was more finished so I could post a more representative picture. Once the patio is done the look will be even better than we originally envisaged. I have attached a few pictures of the room (the white table is only a temporary measure while we wait for the new coffee table).
From first contact to installation, my interactions with FGC have been easy, fast and professional. The end product is superb, we are so happy with our new doors - wish we had done this years ago. Well done FGC!!
This is the second time we have installed FGC and we are very happy with our second installation- very sleek and stylish and all staff very helpful, thanks
Frameless Glass Curtains have few competitors so they could take a lax approach to their work. However, that is not the case. We have had a porch installed in a space that was not square or aligned. The service from survey to finish has been above standard. Barry’s attention to detail and determination that the work would not be complete until his high standards were met was much appreciated. The communication from the admin side was clear and helpful. So all in all we will be using Frameless Glass again and have no hesitation in recommending them.
Brilliant product, what a difference, no frames to block our view of the Brecon Beacons. The service has been the best I think I have ever received and the fitting team were faultless - they travelled 5 hours to get to us in Wales, arriving 30 minutes early, working flat out without a break for 9 hours before driving 5 hours back, all without one complaint!!
Ordered Crittal-style French doors in aluminium. The doors look fantastic and are so much better than the ancient sliding doors I had before. The company were very friendly and easy to deal with. They were understanding of my delays due to a flood. The installers were professional and polite and poor things had to work on the hottest day of the year. Would definitely recommend FGC.
Really great service from this family run company. We love the doors and the install was top notch. Thanks!
Great service and amazing finish! Would highly recommend!
Highly competent office and site staff, great product and at a fair price. Couldn't be happier with the entire experience and end result.
From the beginning to the end, everyone at FGC have been amazing. I knew straight away that the glazing FGC would provide and install would be spectacular and how right that was! The FGC glazing allows our Edwardian stained glass door to still be a main feature and in fact it shows it off perfectly. We are so happy with the end result and can’t praise FGC highly enough, somehow 5 stars doesn’t seem to be high enough.
Their windows are second to none. No other company in Germany, UK or anywhere else can produce such a fabulous product.Any issues that has come up, they always come & fix it. The staff are so nice and polite. For a small company they do really a great job over all. The main things are the frameless bifolds that you hardly have any frame in the line of vision and there is a 5 years guarantee. Mr & Mrs Jahedi
Delighted with our new frameless glass doors. Had lots of lovely comments, even all the trades who have been working on our house have said they've not seen anything like them. Great having something a little unusual. The quality of the doors is of a very high standard. The service from FGC has been very good too, from ordering through to installation. All went very smoothly with no problems. Paid a bit more than regular bifolds, but worth every penny. Best decision, no regrets at all.
Great service and very welcoming for my father and I. Adrian in particular was very efficient, gave great pertinent advice and guidance on my future purchase!
Excellent in all aspects from initial viewing in showroom to actual installation.
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.
Great company with excellent, friendly and responsive service, the guys were helpful and efficient with the installation and the slide and turn doors are a fantastic product.
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!!
The quality of the windows / doors are second to none.The customer service was first class from placing the order to installation we were kept informed at every step.The installation team led by Richard left our house and patio cleaner than when they arrivedI would recommend FGC 100%Tony- Burnley
From start to finish everything was excellent.Fab u lasThank you
BRILLIANT SERVICE FROM START TO FINISHHighly recommended.
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.
I love my doors! It’s transformed my place. The people are great, no nonsense, organised and efficient. I’d recommend them to anyone
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.
Response from the owner: Hello Ian, thank you very much for leaving us a review and glad you're happy with your doors and our service.
Great staff and great products! Have visited the showroom to view doors, really loved all of them! Have referred to a friend - Can't recommend enough
Really great doors. Really are something different. Expensive, but you really pay for what you get here.

Re delivery, there was an initial hope that you might be earlier than the 6-8 week lead time, but once that wasn’t going to happen, you gave us a date, and were then able to bring it forward a couple of days to fit around our holiday schedule, which was great.  Guys turned up at 8am as expected. Your guys were clean and tidy. I love the doors and think they are great.  I would

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

We are absolutely delighted with the doors, they are so classy and modern. Paul (FGC) was excellent and knew his job. The workmanship is superb. All our friends and family think they are fantastic. Thank you once again.

We used FGC to manufacture and install frameless glass doors on all three sides of a large terrace bay. The design was complex and required a flexible and innovative approach to their existing designs. The result was outstanding – clear uninterrupted views over the countryside and a flexible opening pattern which allows fresh air no matter the weather. FGC worked well with the architects and builders on this major project and have provided a responsive

We were recommended to use FGC by our builder and one of us visited a client who had recently had his installation. We have been hampered with delays regarding our lounge where the doors were being installed so it was refreshing to have FGC arrive at 8am and be finsihed installing and waiting for a sign off by 1pm. The work was quick efficient and faultless. We would highly recommend the product and the service

We chose FGC because we wanted something unique to connect both garden and our new room. Unique design, simple flawless construction, ease of use and durable construction all fit perfectly with what we wanted. FGC further enhanced the fit with great service and on site installation, answering any further queries we had very quickly. 20150112 Mr

Regarding your service I would like to make the following comments Web site, initial contact and service My wife saw a product similar to FGC Glass Curtains whilst on holiday. After undertaking a lot of searching on the internet we came across FGC. FGC offered a product we could not find anywhere else, i.e. a true frameless glass product, no side borders, only the top and bottom running rails. The product looked as if you

The service I received from FGD was professional and prompt from the initial on site survey through to installation and completion. Added to this the finished product has exceeded my expectations. It has enhanced my home with style and individuality, and enabled me to make use of the space in a way that is ‘unique’.

We were very happy with the service offered from start to finish. The frameless glass doors are a perfect solution to our extension and have received many compliments.The workmen who installed the doors were courteous and efficient, the job completed in a few hours, we had a slight problem that needed attending to and this was resolved immediately. We would not hesitate to recommend this company and their wonderful products.

After researching the market for a contemporary sliding minimal frame patio door, we were delighted to come across Frameless Glass Curtains. We were so pleased with the doors we ordered another set for the dining room and were not let down – the service we received was consistently good from staff both in and out of the office. From the start they have been knowledgeable, polite and happy to spend time helping us with our

A heartfelt thank you from us. We knew we wanted something a bit special to set off our extension, which has been absolutely essential in making our new home work for the family. We scoured the internet for something that would allow an uninterupted view of the planned garden but would also allow us to throw back the glass in the summer to bring the garden into the house.
