Truly outstanding company.

Global windows replaced all our windows, 2 doors and 2 large patio doors. From start to finish this company have been amazing. Nothing has been too much trouble. They’ve made us feel so valued and respected. We’ve felt so comfortable with the team of fitters in our home. Not just the fitters but everyone else involved in the job. Right down to the office staff. The whole team is amazing. We could 100% recommend this company. All our neighbours have commented how amazing the house looks. Thank you global.

we keep coming back.!

A very professional, efficient and thorough service. Top quality products.
We have used Global over many years to fit replacement windows, a new conservatory with solid roof and just last week a new back door.
They never claim to be the cheapest but I can vouch for quality that lasts, workmanship that is top notch and always, always a very good After sales service.

From the first visit to the final installation nothing was too much trouble for the global team. We were kept well informed of each stage of construction and people attended when they said they would. We are pleased with the new conservatory solid roof and for the outstanding service provided, no issues whatsoever. Thank you.

Highly recommended Global

Global have been amazing from start to finish . We have found the company to be professional in all our communications very quick to respond to our questions before the installation of our windows and doors . The fitters who installed our windows and doors were such hard workers they were relentless in getting everything installed to a very high standard and they were working in extreme heat we have had recently.
We are honestly so impressed with the quality of the work and the work done prior to fitting.
We wouldn’t hesitate to recommend Global to anyone considering having windows and doors or conservatories.

OMG! What a transformation!

OMG! Why did I wait so long?
What a transformation, the windows are STUNNING!
Andy and Lee did an incredible job fitting them - we're an old property and it's not easy but they made it look easy ( it wasn't!)
From sales to surveyor ( another Andy) what a pleasure and Pat in accounts, brilliant too.
Bravo Liam and team, what a service, what a business.
Thanks all.
PS New bifolds next!
PPS I never knew I could be so excited about windows!
Shoes, handbags and now windows and doors!

Wow, thank you so much for such an amazing review! 😊

Reading comments like this really makes our day. We're absolutely delighted that you're so happy with your new windows, especially in an older property where every installation comes with its own challenges. We'll be sure to pass your kind words on to Andy, Lee, and other Andy (our surveyor), and Pat – they'll be thrilled to know their hard work made such a positive impression.

We pride ourselves on making the whole experience as enjoyable and stress-free as possible, so it's fantastic to hear that reflected from start to finish.

We love your PS and PPS... who knew windows could compete with shoes and handbags! 😄 We can't wait to help you with those new bifolds when you're ready.

Thank you again for choosing Global Windows and for taking the time to share your experience. Enjoy your beautiful new windows! 😊🌍

Replacing Edwardian sliding sash windows

Having previously bought (direct from the manufacturer) a uPVC sliding sash window and fitted it myself, (five years ago) I was very impressed with the quality of these Kwikslide units.
I wanted to replace the original 120 year old bay window and two others, whilst retaining the original Edwardian features, but I was aware that replacing the bay was beyond my capabilities.
Kwikslide put me in touch with Global Windows, Trevor came and measured up, showed me before and after photos of a similar installation to ours, and produced a quote with which I was happy.
This was in October 2024 and due to outside circumstances, we had to postpone the project until May this year.
There was no nagging or 'special offers' in the interim - Trevor returned, confirmed the original price still applied and quoted a 6 week schedule. A very thorough surveyer (whose name I didn't get) came and took all the fine details.
Six weeks later Andy (tea, white, no sugar), Lee (are you happy with that?) and Morgan arrived and adjusted their preferred order of work to accommodate my bedbound wife's daily routine.
The ancient rotten bay was carefully removed, and like most old properties nothing was plumb or square - Andy took great pains (panes?) with the positioning and alignment of the 3 units to make sure it was the absolute best it could be, a true perfectionist. God is always in the details and the care taken with the finishing seals and trims was exceptional.
The other two windows produced their own challenges which were all carefully handled.
All the way through they patiently put up with the demands/questions/suggestions of a very particular customer (me) and made sure I was happy with what they were doing. They meticulously cleaned up (thanks Morgan) as they worked and took great care in the making good of the original cills, reveals and architrave.
Overall I am delighted with the results and will happily recommend Global Windows - indeed my daughter and her husband have just ordered new windows having seen the quality of ours.
A big thankyou to all at Global.

Thank you so much for your fantastic review and for taking the time to share your experience.

We're delighted you're so pleased with your new Edwardian-style sliding sash windows and that we were able to help preserve the character of your home. Your kind words about Trevor, our surveyor (also called Andy), and Andy, Lee, and Morgan mean a great deal, and we'll be sure to pass them on to the team.

It was a pleasure working with you, and we're especially grateful for your recommendation to your daughter and her husband – that's the highest compliment we could receive.

Thank you again for choosing Global Windows, and we hope you enjoy your new windows for many years to come 😊🌍

I had a very good service from the onset from making general enquiries, taking measurements in my home to the installation. Everyone was very courteous, answered all my questions, and the installation was carried out quickly and they cleaned up afterwards, and I am very happy with the outcome. I used Global many years ago and found they have kept their high standards. I would certainly recommend Global to others.

Best window company around !

Best window company around. We had our door fitted a few years ago and Trevor the advisor was fantastic really helped us pick the perfect door. When the door was fitted it looked amazing top quality and lovely colour. We decided to go back to global for all the windows. We was lucky again to get Trevor, who helped us pick the perfect windows for our property. Again first class service from the 2 fitters that came . The windows look fantastic after completion and has totally transformed our property. Would higher recommend this company. Thank you very much.

Brilliant

From walking in off the street to placing the order to the finished project. It couldn't have been easier. Russell advised on the order specs and kept us informed up until fitting day. Alan and Lee came on the day cheerful and professionally fitted the new door. The finish and cleanliness was second to none. So much so I returned to purchase windows.
You walk in as a potential customer and leave as a friend. I cannot recommend highly enough.

Just had a second lot of windows installed by global as we were pleased with the first. The most recent installation have a kind of opaque glass fitted because they are very overlooked and we are so pleased with them. They stop anyone seeing in but allow so much light through. Before we had to have blinds up but now we need nothing.
