Meet the teams

Win-Dor have over 35 years of experience in the fenestration and glazing industry – having grown to become one of the country’s leading suppliers of uPVC and aluminium windows, doors and conservatories.

A huge part of our continued growth is due to the hard work of our committed, knowledgeable staff. Win-Dor on its own employs 32 dedicated staff, as part of the 250 working for Astraseal as a whole – offering you high end products with local service and industry experience.

At Win-Dor we see ourselves as ‘your local national company’, having enough experience and backing to provide you with quality home improvements, but also with enough local presence to offer a personalised experience.

Window Installers across Oxfordshire, Buckinghamshire, Hertfordshire & Bedfordshire

We have two separate window installer divisions in Milton Keynes and Northampton, so not only do we know these areas well, but you can also come and talk to our teams in our showrooms located in the same areas. If you’d like to know more about the Win-Dor team, you can read more about each of our dedicated installer divisions, or feel free to contact us if you have any more questions.
