Quality Replacement Windows in a range of styles
Here to help
We are a leading (FENSA-Approved) supplier and installer of custom-made replacement windows and doors, based in Gloucestershire.
While bricks and mortar may serve as the base of your home, its character is defined by its windows and doors. So, making the right choices when choosing your windows is essential.
Replacement windows are not just about functionality; they also significantly enhance your home's kerb appeal. With various window styles and colours available, you can customise your windows to perfectly match your home's design.
The styles available for replacement windows are diverse, from casement windows to sash windows. Each style offers unique advantages and can be tailored to complement the architectural style of your house. For instance, casement windows provide excellent ventilation, while bay windows can enhance interior space and light.
Window colours have evolved beyond the standard white or wood finishes. Today, homeowners can choose from a wide palette of colours, allowing for a more personalised look that can make your house stand out. Whether you prefer bold, contemporary hues or classic, understated tones, there's a colour option to suit every taste.
Older windows can be a security risk, often being easier to breach or lacking modern locking mechanisms. Replacement windows offer enhanced security features, giving you peace of mind. These features help keep intruders out and make your windows safe for daily use, especially in homes with kids or pets.

That’s why we advocate for a personal, in-person approach. We will give you important guidance and answer all your questions. We will also provide a free quote with a clear breakdown of costs to help you make your decision.

Glevum Windows and doors are of excellent quality and the fitters, Matt and Dean were both quick, efficient and tidy workers. We found them both friendly and polite. We would not hesitate to recommend the Company and the service they provided.

A very personal service; I felt valued as a customer and they listened to what I wanted. Excellent quality of product and service. I decided not to go with a larger well-known brand as they did not provide the same personal service in the quotation stage.

Fitters are skilled and careful. Products are not the cheapest on the market but they are of the best quality and extremely good value for money.
R. Savage (Worcester)
Excellent service from start to finish, we had secondary Glazing fitted into our dental practice. Glevum attended when they said they would, completed the job with minimum disturbance to the daily running of the practice, and left their work place clean and tidy. The glazing has made such a difference, staff are much warmer and the radiators have been turned to low.
H. Pugh (Gloucester)
Glevum were prompt in quoting for the work. The order was placed and doors and windows far more quickly than other companies were able. The fitting was completed to a high standard. I'm very happy with the work and product!!
