A huge range of windows, doors and conservatories from Sevenoaks' local double glazing experts

Surrounded by a variety of quaint Kent villages, such as Sundridge and Igtham, we’ve been serving Sevenoaks and the neighbouring area with competitively priced double glazing products for over 50 years. From bespoke heritage windows for stunning Sevenoaks period properties to ventilating and illuminating sash windows for elegant Victorian homes, right through to more modern double-glazed offerings and functional yet versatile conservatories in Sevenoaks, we have a wealth of local knowledge to share.

Located in western Kent, 32 miles from London Bridge, the charming market town of Sevenoaks is renowned for its excellent transport links to the capital. Popular with commuters since 1862, it’s named after seven historic oak trees standing proudly on today’s cricket ground site.

With a rich history dating as far back as the 13th Century, Sevenoaks boasts many beautiful green spaces, including the National Trust Knole Park; home to herds of wild deer, unusually, just a short walk from the high street.
