Report
Used Global Windows to replace three first floor that had 'blown', across the front of our house. Mark, the window fitter, was efficient, skilled and paid great attention to detail, going above and beyond to make us happy with the installation. The quality of the products is very good and have enhanced the look of our house. Mark cleared up as he went along and left the work area tidy, both inside and out! I would recommend Global windows as they are also a local company and very competitive price wise. Well done Global Windows! Steve & Joy

Report
From the first time we popped into the showroom for a chat, to the final payment, everything about our conservatory roof replacement has been excellent. Everyone at Global has been both pleasant and professional. The price they quoted us was fair. All work started and was completed on time, and we had visits from the Project Manager almost every day. Although different teams were involved (roofers, electrician, plasterer) they all communicated with each other, so they all knew what was going on, and what our requirements were.
They were great at keeping us up to date as work progressed, and we got a daily update before they left the site each day. Work was completed to a high standard, and they were very respectful of our property and always left the site clean and tidy. 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.

Great company came measured & gave us a price. Told us a fitting date confirmed the date, & two great lads came on time & fitted the doors cleaned & tided up after themselves. What more can you ask for. Fantastic, it's the second job they have done for us, & I won't hesitate to refer or ask them back for another job.

Global Windows fitted a total of 21 windows to our property, including more technical bay windows and orbital windows, and we couldn't be happier with the result. From the quality of the product to the pristine fitting and finishing by the highly skilled fitters Global performed to a high standard in all departments. We would recommend Global Windows to family and friends without hesitation. Thank you
