M. Wear (Gloucester)

Every member of staff we have dealt with provided excellent customer service they were friendly and professional. We are happy to recommend the company.

S. Groves (Swindon)

Excellent service from start to finish. Well explained on the initial home visit and questions answered fully. Easy to make payments and such a professional and pleasant experience. I would recommend to others and would definitely use the company again.

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)

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.
