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.

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.

Customer Testimonials

If you are unsure about exactly what you want - then visit the showroom where really sound advice is provided. Often you will consider a product that you may not have first thought was suitable. Nice, friendly, customer focused service with a product that perfectly fits the bill. Two years after my conservatory was built - I knew the best place to go when deciding on some new doors. Highly recommended for overall service and price.


I would like to the various people who have been involved in the installation and to add that they were not only very professional in their approach but also very friendly and we would not hesitate to recommend Win-Dor.


Thank you very much for all the help and excellent service provided to us from your staff and team of contractors. We are extremely pleased with the work carried out in an efficient and professional manner – Well done!

From Our Website

Here at Win-Dor, we care about your security. That's why all our home improvement products are accredited by Secured by Design. We want to give you the most choice while still ensuring that security is never compromised. Secured by Design is a police backed initiative that was founded in 1989. Its aim is to prevent the risk and fear of crime. It does this is by setting out standards that windows and doors should achieve as well as new housing developments. To gain Secured by Design accreditation, windows and doors must at least be at PAS24 standard.


Patio doors from Win-Dor offer great aesthetics, and are an excellent choice of door for homeowners wishing to create a wide opening onto an outdoor space. Win-Dor can manufacture and install patio doors which offer some of the slimmest profiles on the market, which means we can offer you better sightlines and a product designed to match our range of windows and doors. Because our patio doors feature especially slim profiles, the door's frame is less intrusive on your property's interior when not in use, and they can help add a sense of openness and light to your home.


If you want a modern alternative to traditional patio or French doors, bifold doors are an excellent choice for the modern, discerning homeowner. Unlike other designs, bifold doors are able to create especially wide openings onto outdoor spaces and seamlessly connect indoor and outdoor spaces, and if you have a preference of material, Win-Dor are able to supply bifolds in both high quality uPVC and aluminium variations, in a wide range of colours and styles. Win-Dor bifolding doors are designed to facilitate open-plan living, giving you the ability to create an aperture in your home up to 5 metres wide.
