Replacement Windows
From traditional white windows to windows with coloured frames and timber-look windows, our windows come in a wide range of colours, styles, and designs to complement your home.
Front & Back Doors
The right front door can create and maintain a great first impression. A pair of French Doors, a set of Sliding Patio Doors, or bifold doors can better connect your home to your garden.
Entrance Porches
Combine our windows and doors with the desired roof to create a bespoke porch, making the entrance to your home more welcoming, secure, and energy-efficient while adding extra space.
Conservatories
For many homes, space is at a premium, so a tailor-made Conservatory from Glevum will give you more space and act as the perfect link between your home and garden. Our customers regularly tell us that their conservatory has rapidly become their favourite room in the house.
Roof Upgrades
Whether you want a combined glazed and solid roof, a tiled roof with full rectangle glass panels, or a modern lantern roof, a Glevum Conservatory roof upgrade can enhance any style of property, from the traditional to the modern, while removing the issue of a Conservatory being too hot in summer and too cold in winter.
Garden Rooms
The two distinct Garden Room styles can be completely tailored with full-length windows, contemporary insulated side panels, and large integrated fixed glass rooflights to create a unique space. This is the perfect way to create a quiet area disconnected from the house, ideal for a home gym or garden office space.

B Rollins (Gloucester)
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.
N Harris (Pershore)
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.
J. Miller (Symonds Yat)
Excellent everyone was professional and yet friendly. I felt all were giving me good service and I felt a valued customer.
D. Morse (Lydney)
Always helpful and courteous whichever department one is speaking with.
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!!
K. Smit (Bristol)
