No. 1 for new doors & windows!

We had 10 new windows, 2 doors and French doors installed at our 4-bed detached home in Sheffield by Global Windows, and I couldn’t be more pleased with the entire experience. From start to finish, the service was exceptional. The quality of the windows and doors is outstanding - solid, secure, beautifully finished, and a real upgrade to the look and feel of the house. I particularly loved the composite front door, the stylish hardware, the handles, the oak duraboard windowsills, which polished everything off perfectly. All doors also came with three sets of keys. The attention to detail during installation was truly impressive, and the workmanship was efficient and flawless. What stood out even more was the professionalism of Global Windows as a company. Every department and team member played their part perfectly. From the initial quotation and survey, through to fitting, aftercare, invoicing, issuing the guarantee/certificate - it all ran like absolute clockwork. Each team clearly has their own expertise, and the whole process was seamless, stress-free and extremely well organised. A lovely final touch was receiving a bouquet of flowers after completion of the installation, which really showed the company’s commitment to customer care. I would highly recommend Global Windows to anyone looking for high-quality products and a professional, well-managed installation service. A fantastic experience from beginning to end. Thank you Global Windows!

Excellent service from initial enquiry to completion. The window visualiser was brilliant as I wanted to change the style of windows and am so happy with the outcome. The showroom has large range to see for real rather than relying on brochures and the sales team were not pushy. Although not the cheapest quote, I went with Global as the effort they put into sending me visuals, the quality of the products and the previous reviews made the difference.

Several years ago, we engaged Global for a new front door, and the pre- and post-installation service was exceptional, prompting us to re-engage them for the replacement of all windows and back doors. We are highly satisfied with all aspects of the project, including the sales team's professionalism, the installation team's efficiency, and the follow-up communication to ensure our satisfaction.

We were greeted at the Global showroom by a smiling Doug who showed us the Conservatories on show at there showroom. No pressure just helpful advise was given. From Paul the designer, Joe who oversaw the project, Nick ,Si, Craig, & Jordon the Installers/Builders & Plasterers what a team. They worked well together, was pleasant cheerful & helpful if we had any questions during the work. No mess, very tidy & cleaned up every day. We would recommend this Company to anyone and would certainly use them again for any further work we need doing. We look forward to using our new conservatory.

An excellent experience with GLOBAL WINDOWS

From the moment we went into the excellent showroom to the after services (billing etc), the whole experience with GLOBAL WINDOWS could not have gone better. We were left alone to look at the showroom, and when we had questions were quickly helped with real expertise. There was no pressure put on us at this point, or any thereafter. A date was agreed to come and look at our current situation, and we agreed 4 windows and a new door. This was shortly followed by a more detailed survey. The quote was emailed to us, and again we felt no pressure and everyone to this point had been warm, friendly and professional. We accepted the quote and were delighted with how quickly they could be fitted. When it comes to the fitting Andy and Sean were absolutely superb, I cannot say enough about them. They did a superb job fitting the door and windows, bang on time, and were incredibly clean and tidy, you would never know we’d had workmen in the house it was so tidy. One thing to add was that before the windows were fitted we had an issue with the bay window roof and a few tiles missing on the front of the bay. They managed to sort that out too, which was so brilliant. The windows and door are wonderful and have improved the look of the house as well as the condition, no end. Oh the price was highly competitive too. In a world where you are never sure whether you’re dealing with a chancer or someone after a quick buck, GLOBAL WINDOWS absolutely smashed it, I cannot recommend them enough. My

Researching and buying new windows is stressful. Global was our favourite product, the quote surprisingly was the cheapest. Joe the project manager was in constant contact checking the work of his polite experienced team, Brad, Craig, Jordan, Logan, Ash, Sam and Craig the plasterer. As a woman at home alone during fitting, the Global workforce were respectful, polite, and very courteous. The windows and doors look fantastic and are really sturdy. I have no hesitation in recommending Global Windows. Thank you so much 10/10.

Global installed 'state of the art' Upvc windows over 25 years ago to my house and they still perform like new. Now the professional fitting of my new Composite front door has reinforced my opinion of Global. I recommend them for top quality 'value for money' products, expert installers, and aftercare (prompt response to check exterior sealant). CERTASS Certification is the 'icing on the cake'.

I recently had new windows, patio doors and composite door installed by Global Windows and the Service from start to finish was first class. I received a great deal of help in choosing the correct design of windows to suit my property from Trevor whose advice was invaluable. Andy and Sean, the installation team were two smashing lads who were punctual,hardworking and very friendly. The workmanship was excellent and any disruption or mess was kept to a bare minimum. I was kept up to date during every step of the process and I am very pleased with the end results. All I can say is thank you to everyone at Global Windows and I would highly recommend this company.

Global Windows gave us our much wanted extension and delivered everything they promised from the start. The whole process was managed effectively by Joe and all the different teams completing each stage were highly skilled and reliable. It has been such a professional set up throughout and any "snag" was dealt with promptly and efficiently. We would recommend Global to anyone looking for a new build - you won't be disappointed.

New tiled roof to existing conservatory
Customer Service

From the outset of our dealings with Global Windows we were quite impressed. First point of contact being Paul, the Sales Surveyor who explained exactly what the work would entail, including the timeframe. His manner was calm and pleasant with no references to special offers or discounts, in order that he could meet his monthly sales targets. Neither did he attempt to sell us any double glazing or anything else his company deal in, unlike one or two of the others from whom we invited quotes, for our new tiled roof. On the appointed day for the work to begin, Arran and Keegan arrived on time and set fairly to work. Watching the process unfold was quite fascinating, from removal of the old polycarbonate roof to the building of the new structure and finally the tiling itself. Once completed Craig the plasterer arrived followed by Steve, the electrician, to fit the new ceiling spotlights. Lastly but certainly not least the whole job was overseen by Joe, Global's Project Manager, who visited us on three occasions, culminating in him signing off the completed job, once he was satisfied. In addition the office administration work was more than satisfactory, including the process of deposit and scheduled payments. Throughout our dealings, with Global Windows, we found their personnel, friendly, efficient, courteous, hard working and above all professional. 'Smooth and Seamless' is the best phrase to describe our experience. We would recommend the company to any prospective client.

Wow Global... where do i start! Absolutely fantastic customer service from start through to completion. Our project was complex enough to involve multiple teams and each and every one of them went above and beyond and took the stress away. Global set the standard others should follow. Special mention to Allan our first point of contact, Andy and Sean our fitters and Joe who kept everything moving and kept us in the loop at every stage, but equally everyone on our project deserves the plaudits here. All we can say is thanks so much to everyone, we are thrilled with the result. We would not hesitate to recommend Global to anyone moving forwards. Thanks all.

We were building onto our property and also intended replacing existing windows, and were introduced to Global Windows through friends who had replacement windows from them. The ethos of the company appealed to us with the no-quibble, most-current pricing approach together with the standard of workmanship and choice. Our project was quite big so in discussion with 'Global' it was decided to split it into three phases to accommodate our build. From the outset everyone we spoke to was professional, polite and listened to our needs. The windows are of excellent quality and the installation teams were professional and friendly. The after sales service continues in this manner with polite and friendly staff dealing with the associated paperwork. It has been a pleasure dealing with a company which obviously takes a pride in all aspects of its work. We would not hesitate to recommend Global Windows based on our positive experience.

Global Windows provided a great service from the first phone call to the actual installation of 4 replacement windows. The sales assessor's suggestions regarding the design were very useful. Aaron and Keegan arrived on the dot and worked right through till late midwinter afternoon. Very tidy, quiet and helpful workmen. A small unforseen hitch occurred which was fixed immediately on the next working day. I would recommend Global above any other firm.

New sunroom extension

In November 2023, Global Windows replaced our leaky 28 year old conservatory with a properly built sunroom extension. We found them to be a really good company to deal with, and are delighted with the outcome. Global did a great job, from the design advice and the survey, all the way through the actual build. The staff on the project –builders, fitters, plasterer and electrician, were very experienced and their workmanship was to an excellent standard. They worked extremely hard through less than ideal weather, kept to schedule, and tidied up very well at all stages. There were regular site visits from Joe, the project manager, who kept us well informed and dealt very quickly with any queries we had, making the whole process painless and stress-free. The buildings inspector visited several times, and even the owner of the company! The new sunroom has transformed the back of the house. All in all, Global are very professional and well organised, and they delivered excellent value for money; we highly recommend them.

Second composite door ordered and fitted by Global Windows, we had the same pleasant greeting while we were browsing their showroom, and everything from start to finish was just perfect. We had Andy and Sean this time to fit the door and they had to work through a horrid rainy day, but they just got on with it, and all done clean and tidy, two pleasant guys, and the door we picked, well it looks fab, inside and outside.
