Windmill Windows The Company

Windmill Windows is a family run business founded in 1999 and run by it’s two Directors Luke & Abigail Gascoyne. Having grown the company primarily through word of mouth and referrals, they have emphasised the importance of work ethic, professionalism, customer service and expertise through their
now established team to ensure the best service possible is provided to all customers whether it be a single door or an entire house project.

We pride ourselves on our friendly approach and with our accommodating showroom we can help you through what can be a daunting process of choosing what is right for your property. With our knowledgeable and approachable team where the hard sell is forbidden, we really can help you with whatever design and look you are after

Community

Having not only worked with local charities, schools and businesses over the past 20 years with their build / project needs, we have also sponsored and lent a helping hand.
We are proud to be able to say that we have helped local events such as Art on the Hill in Brill, Oak Fest, Long Crendon Christmas Fair, amongst other ones as well as local schools, which gives us great pleasure in being able to give back to the local community when we can. Being a family business with family of our own in the local schools we understand the importance of help that is required in local community that
comes from volunteering and we are very glad we can offer something towards this.

Service and Standards

With our own FENSA registered and qualified installation teams, our attention to detail and respect of our customers ensures that our standard of work and customer service is of the highest quality. We understand that installations can be an inconvenience to day to day life so we go to great
lengths to minimise this and work around you.

We firmly believe that the whole job from start to finish needs to be exemplary, if one part of that process falls down then the whole job falls down so it is imperative to ensure the whole process from the design and sale through to the fitting are all carried out at the same high standard .
