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)

So happy with installation, can really feel the difference in room temperature. Fitters were excellent, very pleasant and left everywhere clean and tidy. Very professional job. Would certainly recommend. Thankyou Glevum.

L. Hollis (Ross-on-Wye)

Excellent service from showroom visit, Rep visiting us to help us choose and price work required, and fitting team. There were small chips on the handles of one window - spotted by the installation team- handles were changed within 2 days. All staff were friendly and efficient, and the fitting team cleaned up after installation. A pleasure to do business with.

This visit was for 4 windows at the front of the house, Next job will be for 7 at the back. Glevum will be our first call.
