Kubu Video Testimonial

Three first floor windows across the front of our detached house

"The three windows were fitted to replace old, blown units. Mark (the fitter) was efficient, polite and skilled. The quality of the units and the workmanship was excellent and Mark cleaned up any mess he made, both inside and out. I was told by the surveyor that the old units would be recycled which is really good in the present climate. Recycle, Reuse, repurpose. There have been no issues since fitting but there is a comprehensive guarantee included, so we have peace of mind for years to come. Well done Global Windows, which I will also add are a local company!"

New patio door.

"Global replaced our old sliding patio doors. The result is a warmer room and an easily opening door. I was grateful that I was able to choose a date which was not changed. Everyone in the process was kind and helpful. It only took a couple of hours and my neighbours who oversaw the job for me said the workmen were efficient and everything was left clean and tidy. Very pleased with the result."

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."

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."

Replace and fit a new door

"Really pleased first-rate door replaced a faulty door from another company. The door is 100% better than the previous door with all the bits that we asked for we got a great installer I would definitely recommend them and will use them again for any windows or doors I need"

Hindsight’s a wonderful thing!

"Global have just replaced our French patio doors, and the difference is amazing. This sliding unit feels solid and substantial unlike the previous. Not the cheapest company in the book, but the attention to detail, product quality and the undoubted expertise of the two guys who did the installation make the extra few quid feel really well spent. I've a bit of a jaded outlook on the quality of current day customer satisfaction ethic, but would suggest that Global has given me hope. Great job."

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."

Changed house windows and front door

"Efficient and courteous and a job well done"

- Checkatrade Review, October 2021

New windows / doors. Removal of external tiles above downstairs bay window and install cladding.

"Quality service from Global from start to finish. After going through the design process and placing order I was given a start date and that was exactly when the installation started. Product exceeded expectations as did the fitters (Andy and Shaun) who were brilliant. We have an old house that has suffered from some movement over the years so it wasn't a starightforward install but they really paid attention to the detail and did an amazing job. Would recommend to anyone."

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."
