Great service!
Can't fault these guys! Professional from initial contact right through to fitting and cleaning up afterwards! Highly recommend this company
Excellent service from initial enquiry to completion. Would definitely recommend and use again. I had a new front door and patio doors with internal blinds installed, both of which I am really happy with. A very positive experience.
Professional from start to finish clear options and great looking door
Very good customer service, delivered door on time, very tidy workmen.
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.
Amazing service from start to finish. Great communication, attention to detail and done exactly what was agreed.
Thank you so much
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.
A company that puts it's customer first. Good price, excellent quality and superb customer communication. I cannot praise this company enough. Delighted with everything, and that doesn't happen very often. Will definitely be back when I need more work carried out. 5*
Fantastic company. From start to finish everything went well Daryl was so helpful on the first visit there was no pressure just very helpful advice
Peter fitted my windows and new front door.. Again no problems at all
Peter is a great guy.his work is outstanding and he is friendly and there was nothing to sweep.up - he did it all
I am delighted with the end result.
I would recommend PT glazing
Thanks guys
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.
Great independent company that cares about its product and the final finish. Highly recommend PT Glazing, they started and finished the job on time. Received good advice on product / style and the fitters were great and took pride in their work. 5 stars from me 👍
Fantastic service from first contact to completion! A really friendly and professional team. The fitters could not be faulted, the finish is stunning and their attention to detail was really impressive. I can recommend PT Glazing.
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
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.
Had a great experience with the whole team and a job well done too.
While we went with an alternative supplier in the end this was not due to any concerns over PT Glazing. Would definitely consider them for any future projects. Excellent customer service and competitive pricing.
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.
Peter and his team are specialists in what they do & have been carrying out work in my family & I’s home for over 10 years.

Their workmanship, professionalism and value for money is unmatched and I would recommend them to any one looking for windows or doors.

Thanks peter!
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.
First rate service. Andrew and his team were courteous, motivated, and when left unattended did a great job. The attention to detail was extremely impressive. The inside fittings and finishes are perfect.
Got back door installed today by Peter and his colleague , what an amazing job they did delighted with it, would 100 percent recommend PT Glazing genuine and so professional. Thanks again.
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. A couple of snags resolved without quibble and even a year on, a quick call regarding an adjustment needed and they guys are out the next day. Professional, courteous and skilled. Highly recommend Peter and his team!
Really happy with my new patio doors, thanks to all the team 👍 would highly recommend- thanks
Excellent work completed. Windows replaced and French doors realigned. Geoff sorted everything and did a fantastic job! I’d be happy to recommend PT Glazing!

Fantastic company to deal with from initial contact, quote to finally fitting our windows.
Highly recommended, a company that actually care about the job they are doing. Peter could not have been more helpful and very professional throughout both the purchase and fitting of our new windows and doors. The guys onsite were friendly and highly skilled. They worked quickly with minimal disruption to achieve a quality of finish that far exceeded my expectations.

Excellent job !! I’m really pleased with my new windows great company to deal with from start to finish very professional and lovely guys would highly recommend.
I would like to take this opportunity to thank everyone at PT Glazing for a job well done. Special thanks to Peter and his team for the brilliant
job they did on schedule. We are extremely happy with our new windows and would certainly use PT Glazing again and recommend them to others in confidence that they would receive an excellent service.
Peter and Brian done a great job replacing my door. Very competitive price, no hassle, turned up when promised and cleared away all the mess. Couldn't be happier with the work done.
Fantastic. Would highly recommend PT Glazing for a first class service getting new windows installed. All of the team were great, really efficient working, and a great quality product. Thanks to Eddie, Peter, Stewart and all the team!
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 service from start to finish. Can’t rate this company highly enough. We wanted a door they didn’t normally stock but they sourced it for us. Nothing was too much bother. Professional, reliable and friendly from first contact. I would happily recommend Peter, Eddie and team.
Great price and quality and right on time....highly recommend using PTGlazing 👍
Use PT Glazing twice now and both times they've provided exactly what I've asked for quality products, Competitive prices and great customer service. As a joiner I will deff be continuing to use PT Glazing
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
Fantastic product, service and fitting. All round recommendation.
Very professional company. Product is excellent and significantly less expensive than well known brands. During initial discussions and quotation, there was no fluff or unnecessary info, just plain talking. I have already recommended them to members of my family who's first impression of them was similarly positive. We have had these windows and the new door for almost a year now and there has been a substantial improvement in performance compared to the previous windows.
Aluminium Casement Windows

FAQs

Aluminium casement windows are highly regarded for their superior energy efficiency and cost-effectiveness, making them an excellent choice for modern homes. They are also celebrated for adding a contemporary and stylish finish to any exterior.

The primary distinction between these windows is their hinge placement. Top hung windows, also known as awning windows, are hinged at the top, which allows for better ventilation and rain protection while providing clear views. In contrast, side hung windows are hinged at the sides and open outward.

Aluminium casement windows provide multiple layers of security. They undergo stringent quality control checks and are designed to shield your home from various threats. Featuring a multi-point locking system and a robust construction, these windows meet the ‘Secured By Design’ standards, which are supported by UK police forces.

PT Glazing stands out due to our accreditation and vetting by notable organisations such as FENSA and VEKA-IN, which attest to our exceptional service quality. As a credible business, we are also registered with the Financial Conduct Authority as an IAR, and with Companies House, and fully compliant with VAT registration. Not many double glazing companies can match our high standards of professionalism and reliability.
