A front door is more than just an entrance—it's the first impression of your home and a crucial barrier for security and energy efficiency. At NZR Windows & Doors, we specialise in composite front door installation across London, Kent, Surrey, and Essex, delivering doors that combine stunning aesthetics with uncompromising performance. Learn more about our full range of residential installations.
Unlike traditional timber or basic uPVC doors, composite doors feature a solid core construction with a Glass Reinforced Plastic (GRP) skin that won't warp, rot, crack, or fade. This makes them ideal for the British climate, maintaining their appearance and performance for decades. If you need door repairs, check our residential repair services.
Every front door we install features multi-point locking systems with anti-snap, anti-drill, and anti-pick cylinders. Most of our doors achieve PAS 24 enhanced security certification, the police-preferred Secured by Design standard. Your family's safety is our priority. See our case studies for examples of our work.
Our A-rated composite doors significantly reduce heat loss compared to older timber or single-glazed doors. With energy costs rising, upgrading your front door is an investment that pays for itself through lower heating bills. All installations are FENSA certified, ensuring full building regulation compliance. Contact us for a free quote.
