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)

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!!
