The Window Wizard – About us

Hi, I am David the owner and sole tradesman of The Window Wizard. Your door and window lock specialist.

We are a local double glazing repair ONLY Company, which is run by myself and wife Clare.

The Window Wizard is a family owned business and NOT a multi-national franchise. Providing our customers with peace of mind, that I will be the only person to carry out your repairs. In addition offering you a continued friendly and personal service.

I carry out double glazing repairs in the Bexley area and the surrounding locations. Offering a UPVC repair service for domestic home owners, letting agents and landlords.

Unfortunately we do not offer a UPVC repair service for commercial properties. As commercial components are very different to these used for domestic windows and doors.
