Composite Doors in Middlesbrough & Teesside
Endeavour Windows are trusted composite door fitters in Middlesbrough, installing uPVC-coated timber composite doors for homes across Stockton, Darlington, Yarm, Whitby, Stokesley and Wynyard.
Transform your home’s entrance into a statement of timeless beauty and modern strength. Whether it’s an inviting front door or a connecting back entrance, our composite doors blend classic timber aesthetics with cutting-edge durability — fitted by our own CERTASS-registered team, replacement and refurbishment only.
Why Choose Composite Doors?
Composite doors fuse carefully selected materials — a solid high-density polyurethane foam core, prized for its insulation, wrapped in layers of Glass Reinforced Plastic (GRP), uPVC and wood. The result is a door that’s visually striking, incredibly robust and resistant to the elements.
Aesthetic design: graceful styling and elegant finishes that lift your home’s kerb appeal and make a lasting impression.
Superior security: multiple layers of robust materials and multi-point locking provide a strong barrier against intruders.
Energy efficiency: the insulating foam core creates an airtight seal that minimises heat transfer for a warmer, more efficient home.
Durability beyond compare: unlike traditional timber, composite doors won’t warp, crack or fade, keeping their looks for years.
Minimal maintenance: no constant upkeep — no repainting or repairs, just an occasional wipe down.

Composite Door FAQs
How long do composite doors last?
A quality composite door, properly fitted, will typically last 30 years or more. The GRP outer skin won’t warp, crack or fade, and it needs only an occasional wipe down.
Are composite doors more secure than uPVC?
Composite doors are generally the stronger option — their layered, high-density construction plus multi-point locking gives excellent resistance to forced entry, all fitted to recognised industry standards.
What colours and styles do composite doors come in?
A huge range — from White, Cream and Anthracite Grey to Chartwell Green, Rich Red and woodgrain finishes like Rosewood and Golden Oak — plus a choice of glazing designs and hardware to match your home.
