Supply and fit new windows and doors

"Competitive price, no pressure at all unlike other companies. Kept fully up to date with courtesy calls and emails. Customer service is excellent. Window fitters Sean and Andy were fabulous. Clean, tidy and friendly but also worked their socks off. Had a little issue with the patio door but sorted this straight away and is now perfect. Would highly recommend. Very satisfied with all aspects from quote to finish."

All upstairs windows

"Faultless experience, everything was perfect from start (quote) to finish. Will certainly use Global Windows again and will highly recommend to friends and family. Massive thank you to the Global Windows team :)"

Professionals. No mess.

"These guys are superb. Andy and Sean are brilliant at their jobs. No mess, everything tidy, very efficient. The quality of the windows second to none. Trevor who initially visited to quote us knows his stuff, no sales pressure. One of the window frames had a slight flaw which I didn't even notice. Andy the fitter pointed it out to me and had insisted on replacing it. Obviously these lads of perfectionists. I would wholly recommend using this company to anybody reading this. I have even recommended them to a friend around the corner who has already agreed an install date."

Guardian roof fitted on my existing conservatory.

"Excellent service from start to finish. I had my existing conservatory roof replaced with a guardian roof. Michael came to give me a quote and then I visited the showroom to see the products. He was helpful and informative. Joe was friendly and efficient overseeing the work carried out. He returned to check that I was happy with the work. The fitters, plasterer and electrician were friendly, polite and hardworking and ensured that everything was clean and tidy before they left. It was great to have been given a schedule prior to the work been carried out. I am really pleased with my new roof."

We were kept informed throughout the process and the guys that fitted the patio door did a very tidy job of it, you can see they took their time to get it right.

We have had 13 new windows and two sets of French Doors

"We are delighted with our new windows and French doors that have been supplied and fitted by Global. Andy and Shaun the fitters have been very professional throughout the process and have been so clean and tidy. From start to finish it has run so smoothly and each stage has been communicated well. Paul, Doug in sales have supported us through the whole process and helped us make some choices. They all work to the current Covid guidelines in these difficult times. Thanks to you all, would highly recommend them."

New Front Door

"We have used Global before and will use them again. Had a new door fitted and the whole experience was great. From ordering to fitting it was easy. All staff are helpful and friendly. The door was fitted on the day as promised and was done quickly to a high standard level. No mess to clean up too. Very pleased with our new door thank you."

- Customer in Sheffield - Checkatrade Review, March 2021

French doors and Composite door

"Went to Global on the recommendation of neighbours. A pleasure to deal with from start to finish. The salesman was pleasant and helpful (in difficult circumstances, as covid plus refurbishment meant we could not visit the showroom). No pushy sales tactics whatsoever. The fitters were very professional. Fast and efficient, and gave the distinct impression that they truly cared about doing a good job. The French doors were fitted with handles that we didn't care for aesthetically, but this proved to be no trouble whatsoever and were promptly changed. Will be using again for future installation."

Replacement Kitchen window

"This is the second time we have used Global Windows and have been extremely pleased with both the product and the service. On both occasions, we were kept well informed from the point of the survey right through to the date of installation. Installation on both occasions was very efficient and completed to a very high standard by their experienced installation team. Would definitely recommend and we will definitely be using them again."

Professional organisation – a job well done through a difficult period

"We are very pleased with the end result - our beautiful new conservatory. This company was recommended to us by two of our neighbours and we are now also happy to recommend Global Windows. The building work was started in August but due to the pandemic there was a delay in erecting the conservatory. However once the materials arrived good progress was made to a high standard throughout."

All glass conservatory

"We used Global Windows after reading their customer rating on Which. The fact that their showroom/office was nearby was a bonus. We can’t praise the service and quality of the conservatory highly enough. The conservatory is quite bespoke. It required a box gutter. There was a small leak. The Global guys promptly sorted it and it’s been fine since. We’re absolutely delighted with our new conservatory."
