I have been buying windows and doors from Quantum Windows for over 25 years. I have always found the pricing very competitive and the quality has been very high. On the rare occasion a problem has arisen it has been dealt with swiftly and efficiently. The office staff are always polite, friendly and professional and we have built a strong relationship over the last 25 years. The drivers are excellent. I know them very well and they have adapted to my ways of working and are always willing to help and accommodated me.

As installers of both PVCu and Aluminium to the New Build market, the importance of on time delivery is totally time critical.
Over the last 20 years Quantum windows have worked closely with PGB to partner with us and deliver our offer to site.
Highly professional, and a pleasure to have worked with them so closely over the years.
