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.

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.
