Practical Entrance Solutions for Modern Homes
While our core expertise lies in timber sash and case windows and traditional joinery, we understand that some properties – particularly those outwith conservation areas – benefit from the practicality and performance of composite entrance doors.
Edinburgh Sash and Case offers a composite door installation service to complement our wider restoration and window work. If you’re already working with us on your windows and need a door replacement that delivers warmth, security and low maintenance, we’ll make sure it’s handled to the same high standard.



Why We Offer Composite Doors
Some properties we work on already have modern entrance doors in place, or are located where traditional materials aren’t a strict requirement. In these cases, a composite door may be the most suitable option.
Composite doors offer excellent insulation, require minimal upkeep, and provide a secure, close-fitting solution for front or rear access. By offering this as a complementary service, we can support customers who want a simple, no-fuss solution as part of a wider window or renovation project – keeping everything under one roof.
