We didn't end up going with PT Glazing to supply & install our new windows. However, I feel compelled to leave a review as they were a standout company to deal with when searching for a window installer in the Glasgow area. Daryl was knowledgeable, punctual and no question was too much for him and the team. The team are clearly professionals with a deep understanding of their products and work hard to understand the needs of their customers. Notably, we had paid our deposit before deciding to go with a different supplier, and they honoured the grace period with no qualms. I have no doubt PT Glazing would have been equally excellent in their installation if we had gone forward with them on the job. I wish them every success going forward.

I recently had all the windows in my 1871 stone property replaced by PT Glazing, including large arched windows, and I couldn't be happier with the entire experience. From start to finish, they were outstanding - excellent communication, incredible attention to detail, and a real commitment to quality workmanship.

Eddie and Peter were always on hand, easy to reach, and consistently responsive to my calls and messages. They took the time to explain everything patiently, making sure I fully understood the process. The entire team was punctual, tidy, courteous, and highly professional throughout.

Not only was the service exceptional, but their pricing was also competitive, which made the decision even easier. Given that my home is in a conservation area, I expected challenges, but they handled everything seamlessly. I honestly can't imagine getting better service from any other double glazing company, and I wouldn’t hesitate to recommend them to anyone.

Having had our main windows replaced by PT Glazing, we decided to replace the windows in our entrance vestibule.
The new windows are identical to our 1904 draughty windows but are draught free and look amazing.

PT Glazing provided exceptional service when I collected my bathroom window. Even though I was handling the installation as a DIY project, they patiently guided me through all recommendations for fitting, tools, and materials. Highly recommend!

After much time searching for a reputable company to supply and fit a new door, I came across PT Glazing who are based in East Kilbride. I couldn’t be more impressed with their service. From start to finish, they were polite, professional, and courteous.
After the installation, they came back to adjust the door to ensure everything was perfect. What truly stood out was their standards of work, going above and beyond my expectations.
Their attention to detail and excellent customer service made the whole process stress-free. I highly recommend PT Glazing to anyone looking for quality doors and exceptional service.

PT Glazing has provided us with a professional and efficient service from start to finish. We love the colour. The veneered glass has really reduced the level of traffic noise and that is a bonus as we live on a busy main road. My thanks to everyone for the work they did and the service provided. Excellent job.

I recently had a new composite front door installed by PT Glazing. The process from initial enquiry to installation was seamless. I chose PT Glazing as they offered a quality product at a competitive pric .and had read reviews from other satisfied customers,.

Peter and his colleague worked diligently, taking care and were respectful of my property. My door fiited, my property was left clean an tidy with no debris of the fiiting evident.

My new door looks fantastic and I will have no hesitation in using PT Glazing for any future work

Elaine O'Hara
I would highly recommend PT Glazing. From the very beginning there was good communication with absolutely no pressure. We were able to go to their showroom to see some doors and to discuss options.
When Peter and his colleague fitted our door it was done with professionalism and courtesy. They tidied up as they went along and there was no tidying up for us to do at the end. The job was done to a high standard.
If I needed any other glazing jobs done I wouldn’t hesitate to use PT Glazing and would recommend to my friends and family.

I haved worked in the construction industry for over 20 years and I spent 6 months researching window companies and getting quotes. I was most impressed with PT Glazing - FENSA registered, insurance backed guarantee and their sales person was honest and friendly.

The job delivered by Peter and his team is first class. There were a few issues which were listened to and dealt with. Outstanding customer service, communication excellent throughout.

I am delighted with the finished windows. Peter even noticed my front door handle was broken and replaced it with a new one without being asked!

Highly highly recommend PT Glazing.

I can’t praise PT Glazing highly enough. From the first visit and measure up through to fitting and aftercare. The fitters laid protective mats all over the places they were working and were courteous throughout the whole time they were here. They absolutely worked their socks off and I trusted the company completely throughout the whole process. Only sorry I don’t have before photos to add as this was a huge transformation.

Stephanie McCabe
We went with PT Glazing because of all the positive reviews and we're so glad we did. It was a great service from start to finish and we're so pleased with our new windows. Everyone we dealt with was so knowledgeable and professional. They answered all of our queries and they delivered the service well within the time scale of 6-8 weeks. It only took 2 and a half hours to replace 2 windows and they had a challenge as our old walls weren't level 😬The 10 guarantee gave us great peace of mind although I can't see us having to use it. We ordered acoustic windows as we live on a busy road and the difference is amazing. We hope to use PT Glazing again and I've also recommended them to our friends and family. Thank you so much for delivering such a good service 😁

Exceptional! Probably the best aftercare service I have experienced from a company.

As you can see from the photos the windows are fantastic. Eddie and the team took our very rotten sash windows and replaced them with much needed double glazed units which are very good quality (they don't feel or look cheap and plasticy). More importantly, they managed to keep the stained glass units which were restored and now honestly look brand new. From start to finish everyone we dealt with (sales/installers etc) were professional and friendly and at no time did we ever feel pressured to buy. There are a lot of companies out there but I wouldn't hesitate to recommend PT to you.

Brilliant work - the guys worked hard and fitted 6 windows and 2 sets of French Doors in 4 days. They were all friendly and efficient, and kept the house tidy each day, taking away the old and clearing up their working site. Everything looks great, the windows are so much better so hoping for a draft free winter in the house !

I can fully recommend the quality of the product and the professionalism of the team
