Recent Bifold Door Installations
“We have had 20 replacement windows, a single door and bifold doors from Double Glazing Direct and are extremely pleased with the result. Gully and Marc are very knowledgeable and it was very helpful that they were able to explain why they use a particular trim or why a door style wouldn’t work, rather than telling me I couldn’t have it.” – Aylesbury Homeowner
“The result is fantastic. We have all new glass, a bifold door on to the garden and a solid and well insulated roof with glass vents, warm and cheap to heat in winter and easy to cool in the spring and summer.” – Buckinghamshire Customer

Are low thresholds available for wheelchair access?
Yes! We offer low-threshold options that comply with Building Regulations, ensuring easy access for all family members.
