About

The widest choice of windows, doors and conservatories in Bicester, Northampton and Milton Keynes

Full house of windows and doors

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.

A company with major resources

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’ double glazing companies that have very little resources behind them. Our sister company is Astraseal, one of the UK’s largest window manufacturing businesses. Being a division of Astraseal means we can give you access to a wider product range and can offer you incredibly competitive prices. We employ 32 staff at Win-Dor, including multiple fitting teams, dedicated service engineers and NVQ qualified surveyors from a wider pool of over 250 staff across the whole group.

The biggest conservatory showrooms in Bicester, Northampton & Milton Keynes

Win-Dor factory and showroom

Need some home improvement inspiration? We have the biggest showrooms in Bicester, Northampton and Milton Keynes – each one packed with a range of stunning windows, doors and conservatories. Why not drop in, speak to one of our friendly sales advisors and see what’s right for you?

Competitive finance options

Can’t afford to improve your home just yet? Don’t worry. We offer a range of highly competitive finance options, including two years interest free, meaning we can find the right package for you.

Non pressure sales

High pressure sales isn’t our style. Unlike many window companies who employ contract sales staff based on commission, all of our staff are employed in-house and aren’t under pressure to win business at all costs. All we care about is doing what’s best for you.

As seen on Cowboy Builders and Better Homes!

By choosing Win-Dor to carry out your home improvements you’ll be working with a company that’s been featured on national TV! In 2014 we featured on Cowboy Builders with Melinda Messenger, installing a new conservatory for a family that had been let down by an unscrupulous tradesman. We also appeared on Carol Vorderman’s Better Homes, a game show that aimed to see who could put the most value on their home, installing both conservatories featured on the programme.
