Called in via a recommendation from another local supplier . Was looking for a obsolete aluminium door handle set . The chap not only had the exact set I needed but also offered a cheaper alternative. This place is a gem ... don't bother online because these guys will know what you want and will probably have one

Professional job and done at a reasonable price. Martin gave me a quote and advised me that the windows could be repaired and gave me a step by step idea of what would be done. The guys who did the job were so friendly and helpful and had both of my window hinges done within an hour whilst I worked from home. Thanks for a professional, trustworthy and friendly service!!! 100% recommended

I have been a satisfied customer of Qualitere Windows since the early 1980's. While other window companies have come and gone Qualitere goes from strength to strength building on their reputation as a professional family business. This summer they replaced all my windows and doors. All materials used from the glass, frames, doors, handles etc are of a very high quality. The after sales service is second to none and I would like to thank Martin and the whole team at Qualitere Windows.
