Glevum Conservatories – The Difference You Can See!
When it comes to home improvement, many homeowners often overlook the conservatory. This beautiful space, designed to let in natural light and provide a seamless connection to the outdoors, can sometimes become less than ideal over the years. If you're contemplating replacing your conservatory, here are compelling reasons to consider making that investment.
- Stylish & comfortable –Is your conservatory feeling dated? Trends in home design change over time, and what once was a stylish addition may now feel drab or out of place. Replacing your conservatory allows you to create a space that reflects modern aesthetics, making your home feel fresh and inviting.
- Adding extra space to your home –Many homeowners find that their needs change over time. Perhaps you need more space for a growing family, a dedicated area for hobbies or a home office. A new conservatory can be designed to meet your specific needs, providing you with a versatile space serving multiple functions.
- Energy Efficient –Older conservatories often suffer from poor insulation and energy inefficiency. If your conservatory struggles to maintain comfortable temperatures in summer and winter, it’s likely time for an upgrade. Modern materials and designs can drastically improve energy efficiency, reducing heating bills and making your home more comfortable year-round.
- Wide range of styles – No matter what conservatory style you need, we have one to match your home and style.
- Design Options to Consider:
- Contemporary Glass Structures: Sleek and stylish options that maximise light.
- Orangeries: A hybrid of a conservatory and extension, perfect for added living space.
- Bi-Fold Doors: These can open up your space to the garden, creating a seamless transition between indoors and outdoors.
- Design Options to Consider:
If Planning Permission is required, we will obtain it on your behalf to ensure a seamless, hassle-free experience.

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)

D. Morse (Lydney)

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!!
