We Are Castle Glass

We are Chalfont St. Giles’ leading home improvement specialists. Installing a broad range of high quality products from an array of the market’s leading suppliers, we take pride in being a reputable and reliable name in this area. We thrive off word of mouth and recommendations, in return treating local homeowners with respect and valuing their trade.

We are a family-run business, something we have maintained since we opened our doors several decades ago. We feel this separates us from larger national installers, as you’ll instead receive a warming, friendlier customer service from a tight-knit team. This takes the stress away from having new windows or doors installed in your home.

Products We Offer

We consider ourselves to be a comprehensive home improvement specialist. With this, we offer a broad array of renovation options, catering to every possible need you might have. What’s more, you can complete your entire renovations with one installer, rather than having to juggle more than one if you’re making more significant changes to your home.

We offer a comprehensive range of windows, all fitted with double glazing. This includes casement, tilt and turn and sliding sash windows, as well as aluminium frames and profiles from The Residence Collection. We also install front and back doors, including composite, stable, bifold and patio variants as well as roller garage doors.

What’s more, we at Castle Glass also install a high performance range of conservatories, extensions and orangeries, as well as individually offering the roof systems and lanterns. Our product ranges also stems to roofline, with fascias, soffits, guttering and cladding all on offer. What’s more, as we craft all glazing in-house, we can also cater to bespoke glass requests.
