GHI Windows

Ghi installed my flush r9 windows and sliding frameless doors 3 years ago, the level of service was fantastic. I am so pleased with the outcome I have just ordered the same windows and doors for my new house after Visiting the Banstead showroom. Very excited & thanks again!

The team provided us with a lovely black aluminium picture window. Outstanding service and quality

We recently had our windows installed by GHI Windows, and I couldn’t be happier with the result. The windows look absolutely beautiful and have really transformed the property. Carl and his son Kai were fantastic from start to finish. They were here all day, worked efficiently, and maintained a very professional attitude throughout. It was clear they take real pride in their work. The service was quick, smooth, and completed to a high standard, with everything left clean and tidy afterwards. It’s not always easy to find reliable tradespeople, but these guys were excellent. I would highly recommend GHI Windows to anyone looking for quality workmanship and a professional, friendly service.

The company inspired confidence from the start, for what was to us a daunting prospect. We wanted to have all of our windows and the back door replaced. We also had some half walls knocked out and replaced with full length panes and patio doors. Our Installation team, Carl and Kye, were absolutely excellent and had a clear understanding of what was required. They worked consistently hard for 7 days and did a first class job with a meticulous finish.

A great experience from start to finish with GHI for two new sash windows and a new front door. Steve in the Weybridge branch was incredibly helpful - with no question being too small. Come installation, Peter and Harrison were fantastic and left the property in a fantastic condition. Now already planning the next window upgrade with GHI.

We had new windows and front door fitted by GHI in October 2025 and are really pleased with them. Lance in the showroom was super helpful at explaining our options, including fittings and colourways. Carl and his son who fitted the windows were professional, friendly and really really careful to minimise any damage to the house. We couldn't recommend them enough. Price was competative. Very pleased with the results!

Can’t fault them! Friendly, trust worthy and very professional! Having work done when you have small kids is always a fear and they couldn’t have been more accommodating! Would recommend 10000% what a great father and son team!

Windows and doors fitted today by Carl and Kai service was excellent and to a professional standard . They were friendly and very polite thought out the day highly recommend them .

Looks amazing. Very happy with the service and communication.

We've just ordered our new windows and doors with GHI. We are so happy with the buying process. Jim has been helpful from the very first conversation - he talked us through all the different options and price points and gave us some good, honest advice. Jim also spent time with us in their showroom showing us all the options, it really helped with our decision making to be able to see examples of the different doors and windows. Can't wait to have them installed!

Carl and his Son finished our windows and doors this week from GHI Banstead, what a fantastic job they did , nothing was too much trouble, the quality of the windows and doors is fantastic, price wise they very competitive, I can not recommend them highly enough, really professional, really polite, a pleasure to have in our home , and Jim who came out at the beginning to see us was so helpful and very honest with his suggestions and opinions. We got exactly what we was told , what a great team of people. 10 out of 10

Tony and Jordan were amazing what a fantastic job they did. I am having new windows fitted and have asked for them to come back. Had Tony back to fit another 6 windows and he did a brilliant job again. It has been a great service from Phil coming round to measure and give me a price to the surveyor coming round to double check the measurements before ordering the windows. I would definitely recommend this company for its excellent service

I am delighted with the work that GHI have done for me so far. My windows look fantastic. I am now looking forward to having the front of my house done by them as well. The staff throughout the company that I have dealt with particularly Michelle from the Weybridge branch have been particularly impressive. If only all companies were as easy to do business with !

Tony and Tom were fantastic! They were friendly, punctual, and completed the door installation efficiently. They also made sure to clean up afterwards, leaving everything neat. I would highly recommend their services.

Fantastic service from GHI, couldn’t be happier. A big thank you to Tony, Alfi and Tom who fit 12x new windows, 2x patio door and 1x side door and window to my house. Fantastic team, really clean and really tidy and a lovely bunch of lads. First class fitting. Thank you

The salesman Tom was informative and knowledgable and the admin team kept us updated throughout the process. The installers Tim & Tom were polite, respectful, clean and extremely tidy. Their workmanship and their attention to detail was fantastic. The difference with our new door & windows is amazing. Both my partner and I would highly recommend GHI Windows.

The fitters at GHI worked so hard and finished the job beautifully. Lovely to have around too. I’m delighted with GHI and the windows and would strongly recommend.

Lovely 2 men installing my new door. Amazing work, they were friendly, quick, funny and overall great finish. Thanks again!
