We are delighted with Global windows! The salesman was knowledgeable and helpful and not at all pushy. We have been kept informed throughout by courteous friendly staff. The fitters arrived promptly and remained cheerful and hardworking in spite of being drenched on their previous job. The patio door is attractive and of high quality and we are now much warmer without the drafts. Also good value for money compared with other companies and no hidden costs. Thank you

Global Window came highly recommended from a family member and safe to say they were excellent. Prompt on quotation, measuring and fitting despite well known supply issues across most industries. One thing I hate is quotes that come down by half after youve negotiated, this is not the case with Global, best price given first time which was great and where it should be to be competitive (I head up a procurement department).
Installation, quality of work, communications throughout were fantastic, a company thats a credit to Yorkshire. Keep up the excellent work all!

From order to fitting Global Windows have done a really good job. The sales man was helpful without being pushy. Lead in time was approximately 3 months but in fairness they told us this right from the start and actually fitted the door about 8 days earlier than planned. The fitter had a bit of a nightmare fitting the door but he persevered and made a lovely job. Dust sheets were laid on the floor and furniture. Everything was made good and They even brought a vaccum cleaner. Very pleased.

I,m so glad I had global windows to install all my windows in my home . From the gentleman that came out to do all the measuring he was very polite and explained everything in detail regarding what style of windows I wanted and how they would Benefit me and that my home would would be a lot warmer which I have noticed a difference straight away .the two men that came out to fit my windows were very professional, polite and they made sure that all the areas that they were working was covered with sheets . They cleaned up after themselves there was hardly any mess at all they did a fantastic job
