Prestige Windows & Doors: proudly manufacturing home improvements in the South East

At Prestige, we don’t just install windows, doors, and conservatories, we manufacture and fabricate them in our specialist factories too. As proud British fabricators, we operate from two state-of-the-art sites utilising the latest in machinery and technology.

With competitive prices, flexible lead times, and years of valuable experience, the Prestige brand is the first choice for the South East construction and fenestration industry.

Our factory in Ongar, Essex

Based in beautiful Ongar is our state of the art modern production facility. This factory has received substantial investment in machinery including a new cutting centre and CNC (computer numerical control). This has automated the production while increasing quality and decreasing lead times.

High-performance products and services enable us to retain an extensive trade base, who return time and time again for the exceptional quality and customer service that our expert team is renowned for.

Had my front and back door changed. Kamlesh was very professional, he came to inspect the property and provided a quote. We went online and order which door we liked (type, colour, door furniture). 4 weeks later it was ready and they installed it in 1 day. Everything works great and they were a pleasure to deal with.

Extremely happy with the work carried out of having new windows and front door installed. Having these changes have made our home not only look different but warmth and something to be proud of. Great work by Kamal and his team would highly recommend them to anybody and definitely use them again near future.

Great little company! We commissioned them to install a porch and we were VERY particular about the style, profile and dimensions. Kam worked with us to come up with a design that we were happy with and the installers were brilliant, with a real attention to detail. We had an issue with the brick laying but they had it all taken down and redone for us, so we were happy with the solution. Our porch is the best on the street! Recommended
