Premium Composite Door Replacement for Portsmouth homes
Professional composite door replacement service across Portsmouth and the wider PO area. Fully guaranteed, locally based, and ready to help today.
Composite doors are the modern standard for front entrances across Portsmouth. They combine a solid timber core with a UPVC subframe and a tough GRP (glass-reinforced plastic) skin — giving you a door that looks like timber, performs like UPVC, and provides far better security than either. Across the city we fit composite doors most weeks as upgrades from older UPVC, particularly in security-conscious areas where break-ins are a concern.
Restoration Glazing supplies and fits composite doors across every Portsmouth postcode (PO1 to PO6). We work with the major UK manufacturers (Solidor, Endurance, Rockdoor, Comp Door) and offer hundreds of style, colour, and glass combinations. Every composite door comes with a 10-year guarantee on the door body and 5-year on the multi-point locking mechanism. TS007 3-star or SS312 Diamond anti-snap cylinders fitted as standard.
Composite door replacement in Portsmouth typically costs between £1,000 and £2,200 fitted, depending on style, glass design, and hardware. Stable doors and double-leaf composite door sets are at the higher end. We provide a free survey and fixed-price written quote — no high-pressure sales, no "today only" pricing tactics.
Why Composite Door Replacement Matters in Portsmouth
A composite door replacement in Portsmouth is the ultimate upgrade for your home's entrance. Composite doors combine a glass-reinforced plastic (GRP) skin with a solid insulating core to deliver the elegant appearance of a traditional timber door with none of the maintenance headaches. Across this historic naval city, from period properties near the Spinnaker Tower to modern homes in Southsea and Fratton, composite doors are rapidly becoming the most popular choice for homeowners who want the best in security, insulation, and style. Portsmouth's island geography and constant exposure to sea air makes composite doors an ideal choice, as they won't warp, rot, or fade like timber alternatives.

Frequently Asked Questions — Composite Door Replacement Portsmouth
How much does a composite door cost in Portsmouth?
Most composite doors are £1,000-£2,200 fitted, depending on style, glass design, and hardware spec. Standard front-door styles in popular colours (anthracite, navy, white) are at the lower end. Stable doors, double-leaf sets, and bespoke colours are at the higher end.
Composite door or UPVC door — which is better for my Portsmouth home?
Composite is more secure (solid timber core), more thermally efficient, lasts longer (typically 30+ years vs 20-25 for UPVC), and looks more like timber. It's £300-£800 more expensive than UPVC. For front doors — particularly important in higher-burglary Portsmouth postcodes — composite is usually worth it.
How long does it take to install a composite door in Portsmouth?
Survey takes 30 minutes. Manufacturing is 4-6 weeks for standard styles, longer for bespoke colours and stable doors. Installation is typically completed in 3-4 hours, with the old door removed and new one fitted in a single visit.
Are composite doors secure in Portsmouth?
Yes — every composite door we fit comes with multi-point locking (typically 5-7 locking points), TS007 3-star or SS312 Diamond anti-snap cylinder, internal hinge bolts, and reinforced strike plates. They meet PAS 24 enhanced security standard and most UK home insurers categorise them as "high security."
