Testimonials

Our customers' feedback is important to us. Read our latest customer testimonials below.

Conservatory Roof Replacement

"From first to last this company is excellent. Fair price, work completed to a high standard and great communication throughout. Daily visits from the Project Manager. Pleasant and professional team throughout. Respectful of property, our home was left clean and tidy at the end of each day. Having work of this sort done was a big investment for us, but we felt confident that they were looking after us throughout. We gladly recommend them to anyone considering a conservatory roof replacement. And now that the roof is done, the conservatory is much warmer and quieter."

- Checkatrade Review, April 2022

Putting a solid roof on our existing conservatory and plastering inside

"We have enjoyed our conservatory roof conversion since January. The workmanship was first class, both roof replacement and plastering. The management kept you informed every step of the way. The room now warms up quickly and has been enjoyed throughout the colder weather. We are so happy with the end result. A big thank you to all involved."

- Checkatrade Review, April 2022

Excellent service

"The job was to install a Guardian roof on an existing conservatory. The workers arrived on time and completed the installation in the agreed timeframe and on budget. We were kept informed of who would arrive and when and also of any changes to the original schedule. Final inspection was immediately after completion and any snagging details were completed the next day. A professional service from start to finish."

- Customer in Derbyshire - Which? Review, December 2021

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."

- Checkatrade Review, May 2021

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."

New conservatory roof and bifold doors

"Couldn’t fault from start to finish."

- Customer in Sheffield - Checkatrade Review, Oct 2020

Conservatory Roof

"A great service from Global from start to end. We had a few different quotes to replace an old conservatory roof and create a large opening between our living room/conservatory to make a large room and Global offered the best package. Every one of the skillsmen were professional, courteous, friendly and good-humoured - and great at cleaning up after themselves :) Glad we chose them as the finished result is exactly what I wanted. The Guardian roof gives so much light to what was a dark cold room - I absolutely love it. I would definitely recommend Global Windows."

- Alison Roy, October 2020 - Google Review

Installing a conservatory

"This Company is superb and I cannot recommend them highly enough. All the personnel they used were smart, tidy and professional. Subcontractors were also of the highest quality. The work was done for a more elderly lady and every member of the team really looked after her and treated her with the utmost courtesy and consideration. All the work was to an exceptionally high standard and the team cleaned up each day after work. The company management team kept in regular contact with updates etc. A superb team and COMPANY."
