Composite Doors Harpenden

When choosing the perfect entrance, today’s homeowners are looking for a door that combines style, security, and efficiency — and composite doors deliver exactly that. They have become one of the most popular choices for modern homes thanks to their exceptional strength, insulation, and low maintenance design.

Unlike traditional timber or uPVC doors, composite doors are made using multiple premium materials: a solid timber or engineered core, steel reinforcements, high-density insulating foam, and a tough glass-reinforced plastic (GRP) outer skin. This layered construction provides unbeatable security, durability, and weather protection.

The result is a front door that not only looks elegant but performs to the highest standard — keeping heat in, noise out, and intruders away. Available in a vast choice of colours, finishes, and hardware options, our composite doors from Endurance and Hörmann are designed to enhance any property while providing long-term value and peace of mind.

Whether you’re drawn to a sleek, modern look or a more traditional design with decorative glazing, SDM Doors will help you find the ideal composite door to suit your home.

Harpenden Customer Reviews

“

We wanted to replace our tired old front door with something that felt more secure and modern, and SDM Doors were absolutely brilliant. From the first visit, they took the time to listen and understand what we wanted — no pressure, just genuine advice. We chose an Endurance composite door in anthracite grey, and it looks amazing. The finish and fit are flawless, and the installation team were friendly, polite, and meticulous. The difference in warmth and soundproofing is incredible. It’s reassuring to deal with a company that genuinely cares about doing the job right.

We can’t praise SDM enough. The service from start to finish was outstanding — prompt communication, expert advice, and a fantastic product. The installation team arrived on time, worked efficiently, and left the place spotless. Our new aluminium front door looks superb and feels incredibly solid. We also had a new garage door fitted last year by SDM, and both installations have completely transformed the look of our home. It’s rare to find such attention to detail these days, but SDM deliver it in spades.
