Composite Door Installation

A residential property in Radlett required a new front door to replace an old, weathered timber door that had swollen, stuck frequently, and allowed cold air to pour into the hallway. The existing door also showed signs of rot at the bottom panel and had a worn-out locking mechanism. The goal was to install a secure, energy-efficient, and low-maintenance composite front door in black to create a bold, contemporary kerb appeal and provide lasting performance.

Our Solution

We supplied and installed a premium black composite front door tailored to the property’s style. The solution included:

• High-density polyurethane foam core for excellent insulation and structural rigidity
• Glass-reinforced plastic (GRP) outer skin resistant to fading, warping, and cracking
• Traditional panel design with decorative obscured double-glazed panels
• External finish in deep black (RAL 9005) for a striking, sophisticated look
• Internal finish in white (RAL 9010) to match the hallway decor
• Five-point multi-point locking system with anti-snap cylinders
• Stainless steel hinges and a concealed letterbox with brush draught seal
• Matching black handles and hardware externally
• White handles and hardware internally for a cohesive finish
• Compressible foam gasket around the entire frame for airtight sealing
