We’re proud to have helped so many homeowners transform their properties with quality products and exceptional service.
A fantastic service, product and install all for a great price. I cannot fault our experience we had with Win-Dor. We had replacement double glazing for our windows and garden room, and it’s made a massive difference.
Olney
Good experience throughout. The sales process was relaxed with no pressure whatsoever, additional requests accepted with no price change. The cost was nearly half that quoted by two ‘big name’ companies over 2 years earlier. The workmanship was excellent from the two-man team of installers. Thoroughly recommend.
Emberton
Great experience all round from the Win-Dor Team. Relaxed and from initial consultation at the show-room, friendly and informal home site survey. Quick and tidy ground works team. Rapid and thorough installation team. Fantastic follow-up service. Highly recommend local company.
Milton Keynes
