Just thought I’d write this review and make the effort to say how happy we are from start to finish with all the team at Global Windows after having all windows replaced on our house. The workmanship and quality is fantastic. The amount of noise reduction and warmth is amazing. Would highly recommend and will use in future if needed with anything else. Thank you to all.

Global windows built my conservatory in 2002. They were excellent in every way so they were my 1st choice when we decided to install a Guardian insulated roof. We had to postpone the original date of the installation because of the atrocious weather in January. Global agreed to this so there was no problem. The installers were very good, workmanlike, tidy and efficient. Costs were as quoted. The roof has made a tremendous difference and I would recommend the installation and the installers without hesitation.

Have used Global Windows twice now, for upstairs windows and also a front door. Excellent workmanship each time, despite some challenges with existing frames being less than square on one side of the house. Work was done on time, efficiently and no mess at end. Very happy with quality of both windows and door - finally have got rid of drafts! Whole customer service and support process was great from start to finish. And great value as well. Have no hesitation in recommending.

Excellent conservatory

Our project was to replace an old lean-to conservatory with a modern and more usable one. We had several quotes but Global were the only company who we felt truly listened to our requirements and came in with a quality design. Once the design was agreed several site visits were made to check measurements and ensure all would fit exactly on the plot. Global are a great company to work with as they have all there own tradesmen meaning they are in full control of the build schedule. Joe kept us informed at all times on how work was progressing and what to expect at each stage. The tradesmen were all very professional, polite, punctual and skilled; they really cared about the quality of their work. They were also extremely tidy leaving the site clean every day. We are absolutely delighted with the result. It’s beautifully finished. We would definitely recommend Global Windows to anyone looking for good quality and design at a fair price.

A brilliant experience from start to finish. Global guided us through the whole process of the build, from planning to itinerary of work, and kept us updated throughout. All of the workmen were friendly, tidy and professional and respected our home whilst they were in it. We know from experience that this cannot be taken for granted! A named contact was always available for us to discuss any questions and issues and the project came in on time and within budget. We are so pleased with the end result which has completely transformed the ground floor of our house. We cannot recommend highly enough.

Absolutely thrilled with our new Orangery. Global are a fantastic team to work with as they have all there own tradesmen meaning everything ran like clockwork even when it was raining non stop they carried on. The guys were all professional, polite, punctual and very skilled workmen. Joe had regular checks on the progress and kept us informed at all times on how work was progressing. All the little finishing touches were completed by the 10th October and the work signed off. We stood back in ore of what had been achieved our Orangery was everything and more than what we could have ever wished for. Thank you to all the Global team.

We had 9 companies quote us for new bay windows, facials and porch with french doors. Global we’re the only company who gave us a quote the same day which was also adhered to with a price that was fair and realistic for what we wanted. The documentation we received throughout has been very thorough ensuring we knew exactly what to expect. From the sales team who were enthusiastic for our plans; knowledgeable and able to advise us of design ideas, friendly and open and honest - far from pushy! To the fitters who could not have done more to keep our property clean and worked hard to complete the job on time, very friendly and respectful of the house. We had a couple of things which need adjusting after the fit however these were completed without question and within days, which again we were really impressed with as we had paid in full by this stage. We could not recommend anyone more highly than Global on every level of service - sales, fitting and after care.

The project undertaken by Global Windows was to remove the old roof of our large (7.5mx5m) conservatory and replace it with a Guardian Warm Roof. From first contact it was evident how much care Global take to understand customer requirements and ensure that all aspects of the job are considered before commencement. A number of site visits were made to check measurements and ensure all our specific requests had been noted. Detailed documentation was received on the the project and all related matters. We consider the price quoted to be very fair and competitive. The installation, scheduled to take a little over 2 weeks, started on time. We could not be more impressed with the team Global deployed to do the work. Not only were they clearly very experienced but they were all equally polite and friendly. Daily visits were made by a member of head office staff to check progress and if there were any concerns. In fact we encountered no problems during the entire installation, which reflects well on their detailed planning and expertise. At the end of each day the site (which after all is our home) was left as clean,neat and tidy as possible. The job finished exactly on time and to budget. Aftercare has been excellent and we are absolutely delighted with the finished product. In conclusion we would say that Global are a thoroughly trustworthy, extremely competent and customer focused company. They have set very high standards and everyone has clearly bought in to this culture.

Everything was very professional. From the salesman to the fitters.They explained everything clearly and delivered on all aspects. We were given really good advise about traffic noise reduction which has made a big difference. The fitting team were friendly, hard working and very tidy, they cleaned everywhere they worked which was 4 rooms in total. Excellent price, product and workmanship. Aftercare was brilliant, checking we had all the documentation we should have and that we were happy with their work. Would certainly recommend and use them ourselves.

The work was completed in a very professional manner and the work area was kept clean and tidy throughout. The standard was what I have come to expect fro this company from initial quotation to completed work. I can recommend them for this roof line type work to installation of composite doors. I considered that the price I was quoted, and actually paid, was fair and reasonable considering the work involved.

Global Windows replaced 4 windows, I had 4 white PVC glazed window units fitted. They were cheaper on price compared to other quotes we had received. They were punctual on the day we had the units fitted. They were quick and they cleaned up after them selves. They were very courteous. The quality of the units is excellent, their sales team were in contact regularly before the insulation. I certainly recommend.
