Customer Feedback
Everything we do is driven by an unwavering dedication to our customers. We thoroughly enjoy the work we do and are proud to know that our customers feel secure and happy with services that we provide.
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.
Thank you so much
The new windows are identical to our 1904 draughty windows but are draught free and look amazing.
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.

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.

uPVC Windows FAQs
Recognised as one of the leading materials for ultra-robust window and door frames, uPVC combines a lightweight feel with long-lasting effects. Standing for Unplasticised Poly Vinyl Chloride, uPVC is championed for meeting the golden trio: low-maintenance, sturdy, and incredibly affordable.
While aluminium is regarded as a modern material, preferred for its sleek, slim appearance, there are a broad range of reasons why homeowners may opt for a more traditional material, such as uPVC. Offering the same level of energy efficiency and durability as aluminium, uPVC provides many of the same benefits, at a significantly lower price.
A lifetime! By following industry best practices, incorporating quality materials, and adhering to specialist installation techniques, we create windows that last. That said, if your uPVC windows were installed before 2000, they may require a replacement due to the difference in manufacturing methods at that time.
Yes, slightly. While a number of variables will impact the price, from size to style, coloured uPVC windows do come with a higher price tag than white windows of the same specification. That said, coloured uPVC is often viewed as a cost-effective alternative to timber, offering many of the benefits associated with premium materials – from noise reduction to durability – without the associated price.
Yes! Offering an insight into your window’s thermal efficiency, level of air leakage, and the amount of solar heat that makes its way into your home, you will be awarded a rank from A to G – ‘A’ being the best.
Ranked on two scales – Energy Efficiency (WER) and Thermal Efficiency (U value) – windows must be ranked at a ‘C’ or above to meet relevant regulations.
