PT glazing have done a fabulous job replacing 2 windows for us. They were happy for us to place a deposit and then wait for a couple months for the actual install while we were juggling some other home repairs. The day of the install went smooth as well. The 2 guys that installed were absolutely fabulous and were happy to explain everything to me and called me over when they finished certain areas to have a look. I also asked if they could leave the glass so I could use it as a cold frame and they taped it up for me so I could store it safely until I need it. 100% will be using them for all the other windows and door we need to replace later down the line.
Response from the owner:Thank you for the the five star review 🙂 We are so happy to about the excellent service you have received and look forward to helping you with any future projects!
PT Glazing installed our new sliding patio door today and we are both so pleased with it. Not only does it look great, but the two men fitting it (sorry I didn't get their names) were great from start to finish! Communication was very good from this company and I wouldn't hesitate to recommend them to anyone 🙂
Response from the owner:Thank you so much for the great review! It is lovely to hear about how pleased you are with your new sliding patio door and the service you have received.
Excellent service. I was very happy with the whole process and would definitely recommend it.
Response from the owner:Thank you Mahmoud for your review and recommandation! We are very happy to hear about the excellent service you have received.
Ian assisted us with a couple of repairs recently and the service couldn’t have been better, from initial diagnosis through to quote and repair.
Response from the owner:Thank you so much for your review on the great service you have received from Ian and the team!
Staff very helpful and efficient. Very good service . Would recommend this company.
Response from the owner:Thank you very much Ann for the review and recommendation!
Amazing company to deal with. With all the window companies I have dealt with, they are by far the most professional. Everything is detailed from start to finish, they even provide detailed drawings and commentary of what will be supplied and fitted.
Response from the owner:Thank you for your rating and review Sunny, it is so great to hear about the excellent experience you have had with PT Glazing from start to finish!
After considering several installers, I chose PT Glazing because their communication and attention to detail stood out from the beginning. Eddie Aslan was very patient and clearly explained the product, specifications, certification, warranty and Insurance Backed Guarantee, while keeping me updated throughout the process. Billy Orr and the installation team were professional and well organised. Richie and his colleague completed the work efficiently and left the area clean and tidy. Lauren was also very helpful with the final documentation. I’m very pleased with the new glazed panel beside our entrance and the overall service provided. I would be happy to recommend PT Glazing.
Response from the owner:Thank you Eddie for your detailed review on the experience you have had with PT Glazing! It is so great to hear you are very pleased with your new glazed panel and the service you have received.
After being caught out with cowboy tradesmen? many years ago we are extra extra wary of who we give our business to. We check reviews etc etc and after looking at the so called established window companies reviews for hours on end, one company stood out by a proverbial mile. That company are PT glazing,its very rare and refreshing nowadays that the owners mindset is the customer comes first. From first contact with salesman Daryl it was an absolute pleasure,no hard sell whatsoever. Daryl asked us what we wanted and gave advice and options when required. We had a rep in our house (days before Daryl arrived) from one of the big companies who had to be chased from our house such was the pressure and stress he was putting us under to buy. Contrast to PT glazing and the easiest sale ever and a pleasure. The difference in prices quoted was also an eye opener as PT glazing were more than half the cost of windows from the established company.The 8 windows were installed last week by fitters who are a credit to PT glazing and 2 absolute gentlemen.All work done by them was to the very highest standards, and these Veka windows are top quality and are better quality than bigger companies are offering at double the price. The double glazed windows are all A+ rated, the triple glazed are all A++ and glass units are all argon gas filled to retain warmth.The windows have transformed our house making it warmer and surprisingly the exterior noise from cars etc is now almost non existent.We highly recommend PT glazing to anyone and special thanks to (owner) Peter and Eddie who made sure we were satisfied with all aspects of install.Meeting Peter in person was a pleasure as his passion for the product/customer service/company was impressive and as previously stated is such a rarity nowadays. Thank you Peter,Daryl,Eddie, and all at PT glazing for a fantastic product and experience, its now easy to see why your company has so many 5 star reviews, bravo.
Response from the owner:Thank you so much for your review! We are so pleased to hear about your positive experience from start to finish with PT Glazing!
Really pleased with the aluminium windows and doors supplied and installed by PT. Quality is excellent, and the installation team were hardworking and professional throughout. Everything was completed to a high standard and the finished result looks great. Would definitely recommend.
Response from the owner:Thank you Muammer for your review! We are very happy to hear how pleased you are with your new windows and doors and the service you have received from PT Glazing.
Excellent company and very friendly. Gave honest opinion and work was very well done ..Used them again and passed his nos to family and she used them also
Response from the owner:Thank you so much for your review - we love hearing about the great service received by PT Glazing!
Very happy indeed with the quality of the products this firm fitted, and with the way they were installed. They came as arranged, put a temporary floor covering down so that our flooring wasn't damaged by the men's boots, and were friendly and pleasant. There now isn't a bar at eye level as you look out of the new windows. This means the view is better and the rooms are now lighter. I wouldn't hesitate to recommend them.
Response from the owner:Thank you very much for your review and kind words James! We have very happy to hear about how the installation was completed and the improvements the new windows have made.
PT Glazing were recommended to me personally by a colleague for the installation of replacement windows as providing excellent service and they did not disappoint! Everyone I encountered at the various stages of the process was friendly, approachable and professional and the installation was carried out efficiently and with clear attention to detail. I was particularly impressed with the efforts made to leave my property in as clean and tidy condition as possible once the work was completed and also to minimise disruption whilst the works were ongoing. I would not hesitate to recommend PT Glazing to friends and family and would certainly use them again the future.
Response from the owner:Thank you so much for your review Irene! It is so great to hear about the fantastic experience you have received and your recommendation.
