Guarantees & Quality Assurance

We sincerely hope that your Glevum windows and doors will give you many years of happiness and satisfaction. In the unlikely event of you having a problem with your windows and doors you have the peace of mind and back up of the Glevum Guarantee.

Glevum offer the full industry-standard guarantee on all our products with ten years guarantee on uPVC frames, the failure of sealed glass units, gaskets, hinges, and locking systems and the colour fastness of uPVC profiles (provided that the customer regularly washes the profiles with warm soapy water) . Please contact Glevum for full details. This guarantee does not affect your statutory rights and applies to homeowners buying windows and doors direct from Glevum. If you are buying a new home with Glevum windows and doors fitted, then your house builder will advise you of the terms of their guarantee.

The Glevum product range uses the highest quality uPVC product range, made locally in Tewkesbury by Duraflex, one of the largest extruders of uPVC profile in the UK. Supplying products for more than 20 years, Duraflex complements Glevum’s experience and reputation for trust and customer service.

To ensure that we maintain the highest possible levels of service we regularly send new customers surveys that ask them to rate their experience with Glevum from the initial enquiry and appointment to the fitting of new windows and doors and beyond.

Satisfied Customers

"I am very happy from start to finish with Glevum and would not consider going anywhere else for windows and doors and I would highly recommend."

K Turnbull (Cheltenham) - Jan'22

"Very professional, efficient and friendly from start to finish. Product is top quality. Installers were superb and went above and beyond what I expected. Very happy with the end result and cannot believe the difference in respect of reduced noise inside the house and insulation properties. This is the 2nd house that I have used Glevum on and would have no hesitation in using again in future.!"

I Davies (Yorkley) - Dec'21

"I have been delighted with all aspects of Glevum Windows. They were tremendously helpful in helping and advising me on choosing the best style of window to suit my old property. The appointment to fit the windows and door was prompt. The installers, Danny and Damion were exceptional. They were quiet, very very tidy, I no mess to clear up, and so pleasant. Glevum were so professional from the start, and I would recommend always. Thank you!"

S Rees (Awre) - Nov'21

"Friendly, professional, helpful, they didn’t try to sell me stuff I didn’t need. The installers were lovely, respectful, friendly, cleared up after themselves, and were a pleasure to have here. Would definitely recommend them although they could do with some singing lessons!!!"
