Want to know what our customers think about GHI? Take a look at some of the glowing reviews previous clients of ours have left us.

I found GHI by searching for window showrooms in Surrey on a google search. Their reviews looked good so I contacted them & a few other companies to get quotes. Their knowledge and advise regarding what would look good in my property was far superior and their pricing was competitive. I have just had the windows and doors installed and am delighted with the products and quality of workmanship. A big thank you to all the team and in particular Jim. Well done. Would certainly recommend!

Sandra Whitton

Just want to let you know how pleased I am with my new composite front door. Thank you to Aaron for a very tidy installation. I highly recommend this company!

Arabella Lions

Having recently moved to Surrey from Manchester I carried out extensive research when deciding to have my windows replaced in my new home. After 3 quotations from national businesses, I decided to contact GHI after finding reviews about them online. This proved to be a much more pleasant and informative experience from the sales point of view. I have just had the new windows and doors fitted and am delighted with the end product, fitting, and the service provided throughout. I couldn’t be happier and had my bi-folding doors installed just before this heatwave. Special thank you to Sean for all his efforts and keeping me informed throughout.

Lauren Groves

Aluminium windows, schuco bifolding doors, and two flat rooflights installed to my property in Banstead, Surrey. Exceptional products, informative, genuinely helpful sales guy Jim, and a first class fitting team led by Phil. I am delighted with the works carried out by the whole team. I had to wait a little longer as a result of this ghastly virus but am extremely happy I chose to use GHI. Will continue to recommend, this is my third property GHI have undertaken works to and I will be sure to use them on the next.

Nicholas Stathan

Extremely knowledgeable staff, high quality products, fair, honest, and competitive pricing. Delighted with my new windows and aluminium patio sliding doors. Installed to perfection and doors glide effortlessly. A wonderful experience throughout and I would certainly recommend GHI.

Michelle Todd

I thought I would take the time to let you know how happy I am with my flush window and folding door installation. An extremely stress free, high quality installation. The guys were very tidy and took lots of care in my home.

Mason Giles

A wonderful job provided by the GHI Windows team. I ordered Origin aluminium bifolding doors, a Solidor, and some residency 9 windows. First class service, fairly priced & fitted to absolute perfection.

Ress Evans

Superior service from the initial visit which has continued all the way till the end when the items were fitted. Flush upvc windows and Schuco bifold doors installed by Richard and his team with great care and attention to detail. Recommend this company very highly, is clear to see how they have been around for such a long time and have so many shops in what seems a saturated industry.

Gethin Davies

Delighted with my new ALUK aluminium windows and doors. GHI have transformed my home with their design and colour advice. Installation team were friendly, worked extremely hard, and provided a superb finish; particularly to windows on the tiled elevations. I am very pleased all around. Please pass on my thanks to the team and try to get my second order in before Christmas.

Sheila Gavigan

So so pleased with my residence 9 window installation carried out by the team at GHI. Would strongly recommend this company to anyone considering this product. I had some residence 9 windows fitted in my last property and the quality of install was nowhere near the exceptional standard produced by the guys at GHI. Thank you very much for a job well done!
