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.
Just had Nick and Brian finish the install. Quality guys, windows amazing, no mess left in the flat. Cheers!
Nick & Brian form PT Glazing did an amazing job Replacing my doors. They finished the job by half a day.
Just had two french windows and front and rear aluminium doors fitted in Jedburgh. Absolutely delighted with them, they have made an enormous difference to the insulation of the house already and look beautiful! The quality of the workmanship just shines through, fantastic team who did an amazing job with very little disruption.Would highly recommend.Denise
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 brilliantjob 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.
PT Glazing are a fantastic company I can't recommend highly enough. Eddie, Peter, Andy and all the boys were fantastic start to finish. Great product, trustworthy company and professional job done! Brilliant. Thanks guys 🙂
New front door fitted recently. Excellent service. Was fitted exactly when they said it would. Very easy company to deal with. I would definitely recommend to friends. Thankyou
Fantastic job - really happy with the result. The Team that fitted the Windows and Door were really good and cleaned up as they went along. Cannot rate this company high enough. Very impressed from the time Eddie came to give quote up to the time the job was completed.
Excellent service and a difficult job well done
Turned up on time did an excellent job,clean and tidy
Friendly, great communication, work was completed to a good standard.
Renewed the windows in my flat. Done a great job at a reasonable price. Would recommend. Thanks guys!
Amazing customer service from enquiry to delivery. Eddie @ PT Glazing was fabulous, so helpful, very prompt and professional in replying to any queries. We couldn’t of asked for anymore, would definitely recommend PT Glazing and would use them for any future projects. Erin and Stuart (Dumfries)
Fantastic service from Eddie and the team. Great communication throughout. Professional service and really happy with end product. Thanks for all your help!
We can recommend the aluminium framed windows which we had fitted by PT Glazing. Expert service was combined with high quality windows - great noise and heat insulation has been appreciated since the new windows were fitted (noticeable as we live under the fly path of Glasgow airport)
I'm unashamedly hard to impress and selected PT Glazing based on fantastic reviews and competitive price. Not many businesses offer both nowadays but Eddie was assuring from start to finish. Superb communication, friendly and articulate. The fitters, Brian and Darren, exceptional. Methodical, fastidious and positive. A credit to the company and pleasure to deal with. Whole house 4 bed exterior glazing refurb done to perfection. I'm delighted. Thanks.
Thank you for your excellent work. The windows were installed with expertise and attention to detail. Brian, Darren and Peter were also very considerate and polite.
New windows are exactly what we wanted. Everything was on time and Eddie kept us updated throughout. The guys that came out were great and very respectful. Highly recommend.
PT Glazing were highly professional at all stages, quotation, contract, installation and after care. The sash & case windows are excellent and match the old tenement timber windows we had before perfectly. Installation was done quickly by guys who arrived on time, did the job and tided up our back court and our neighbour's too. Excellent job. I can recommend PT Glazing without hesitation.
Easy to deal with. Delivered on time. Helpful whenever I called.
I couldn't wait to write my review about PT Glazing. Having researched and used numerous companies over the years (including the "BIG BOYS") I found PT Glazing. Right from my initial contact with the company, they have been excellent, Daryl, Eddie, Peter and team. I have a property that is over 100yrs old so my job was complex to say the least, however they tackled it head on, there were some snagging issues but that is to be expected with this kind of job, the point being they fixed them with no fuss. Their commitment, professionalism and experience is priceless. 5 stars from me who is OCD about perfection and I cant recommend the team enough as they delivered nothing less than that, perfection! Thank you
Was very impressed with Eddie Aslan when he came to give us a quote for our windows, very professional, only reason I didn’t choose them was I decided to go with a Dundee firm as that’s where I live …..
Excellent service. Their advice was clearly about helping the customer what they needed and not overdoing it. For example, we were wondering about triple glaze. Daryl the sales guy said he didn't think it was worth the extra expense. We ended up going triple on some but not on others. If they'd been on the make, they'd have been pushing for max all round. When the guys opened up our old windows they found they'd been fitted with no casement frame. They took the best part of an extra day to build that, sticking to the original quote (but we slipped them an apprciation anyway - they could have not told us and put the windows in badly like before). My only suggestions for improvement are that I would have liked to have had the full technical specifications of the windows more immediately on hand (U values, manufacturers, etc., they got them for me but it took a few days), and I'd have liked to have known more clearly when they'd be fitted, though in January that's weather dependent, so fair enough. Overall, I would thoroughly recommend PT Glazing. Your money goes to a local firm and so stays in the local economy. The fitters were lovely guys who worked like a whirlwind and were helpful in every way. The house is noticeably warmer than before compared with similar outside temperatures.
Pk were amazing..i would highly recommend..the staff were brilliant daryl,peter,eddie & ..fitters jamie & thomas were fab..highly recommend..i love my new windows & door..thank you so much!
Just had new double glazing and front door installed by PT Glazing. All a very smooth and pleasant experience, with friendly and knowledgeable folks, and good communications throughout. Detailed drawings and specifications were prepared in advance, all questions / requests were professionally responded to, and the fitters did a great job in challenging weather. Very happy with the end result. This is an easy 5 stars!
Excellent service and the windows have transformed our house!
Delighted with my new windows and the service from sales through to installation.
Although I eventually did not buy windows from PT Glazing, I could not have received more prompt, courteous or efficient and friendly service.. Their windows look great.
PT Glazing replaced two doors and all of our windows. Excellent service from start to finish. The communication was great before and after we paid the deposit. The standard of work is excellent too.
Windows and doors installed yesterday. Whole process gave us confidence that the company could deliver... tidy organised installation. Having researched the double glazing options and met with a number of installation companies I am v happy that the windows and doors from Veka are the best quality we could have got, and that PT glazing were the best company to rely on for installation.
I am really pleased with my new windows. The quality and service provided by PT Glazing was excellent. From start to finish nothing has been too much trouble and my windows were ordered and installed within a short timescale to fit in with my refurbishment plans. The fitters were clean tidy and delivered the job on the day. In fact that were so efficient they completed the job in less time than anticipated. Thank you very much. I would definitely recommend PT Glazing.
