Some of our happy customers

Here are some of our reviews from our happy customers...

We cannot fault the service we received from the very friendly team. We left them to fit the roof and door while we were at work and when we returned home everywhere was clean and tidy. I can highly recommend the workmanship and the finished product.

Excellent service, Replaced windows, new front and rear door and bi-folds. Were happy to work with our timescales for the new build. The fitters were great clean a tidy and did a lovely job. They were more than happy to come back when we had a small problem with the bi-folds, which was sorted quickly and no issues since. Would definitely recommend this company.

What can I say.. Stuart, Neil, and Stan our fitters were professional, friendly and very tidy. Our new windows look great and it was a very pleasant experience all round. People have been commenting on how much it has changed the look of our house and it all looks to bright and airy inside too. So thank you Thistle Windows for make our home better.

The communication and service from the team at The Windows Shop was excellent. The price was competitive and the following installation was very good. Double glazed windows and a 2/3rd 1/3rd porch door installed, following a detailed survey and discussion on precisely what I wanted, with no problems at all.

Mrs. Holmes

6th May 2017

We had all our windows and doors replaced due to the poor quality of windows fitted by the builders in our new build home! The new Windows have improved our quality of life by providing a draught free much quieter environment the outside stays out there. The Windows are of a good quality and the front door is beautiful. Keith was an extremely hard worker polite friendly and very good at tidying up . We have had occasional problems with the patio doors but as there is a ten year guarantee this has never been a problem and possibly due to the build of the house rather than the Windows. We have always received a rapid response to any issues.Would and have recommended this company to others.

We have had a number of replacement windows, including patio doors, over recent years. The triple glazed units make a real difference to warmth and noise. The fitters Sam & Keith are friendly, consistently do a great job leaving the place tidy, nothing is too much trouble.
