Established in 1978, Win-Dor is the leading home improvement specialist for the Northampton, Milton Keynes, Buckinghamshire, Bedfordshire and Oxfordshire areas. We offer an extensive range of windows, doors, conservatories and orangeries; all of which are available in a wide choice of colours, and are backed by our 10 year guarantee.

Ever heard the saying 'big enough to cope but small enough to care'? Well, this perfectly sums up Win-Dor. We're not a big national company that sees each customer as a number, we're a local company that prides itself on going the extra mile for our customers and providing truly brilliant service. Read our testimonials to see what our customers have to say. We're also unlike the small 'one man band' window companies that have very little resources behind them. Our sister company is Astraseal, one of the UK's largest window manufacturing businesses.
