Composite back doors for homes and businesses in Barnet
Composite door prices depend on the door style, core type, colour, glass design, side panels or toplights, hardware finish and lock specification. Removing an old frame from a deep or uneven opening, or fitting a new threshold, adds labour. See the guide prices for typical ranges; the written quote fixes the figure.
For easily accessible doors in new homes in England, Approved Document Q expects doorsets that resist forced entry, commonly shown by testing to PAS 24. Asking for a PAS 24 tested composite door is a practical benchmark when replacing a front or back door, even though the rule targets new dwellings.
Composite doors do not need painting. Wipe the skin and frame with warm soapy water, avoid solvents and abrasive pads, and keep the threshold drainage clear. A little light oil on the lock gearing and hinges once or twice a year keeps the door closing smoothly, and hinges can be adjusted if it drops.
A composite door slab usually combines a glass-reinforced plastic (GRP) outer skin, moulded with a woodgrain texture, over an insulated core. Some cores are high-density foam, others solid timber. Timber-cored slabs tend to feel heavier and more solid when closed, while foam cores are lighter and insulate well.
What a typical job includes
- Fitting, adjusting, sealing and finishing around the frame
- Written guarantee terms and advice on building regulations sign-off
- Removal and disposal of the old door and frame
- Survey, measuring and threshold check

- Coast
- Barnet is well inland, around 45 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Barnet the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. Dark-coloured doors in direct sun get much hotter than pale ones, so follow the manufacturer's guidance on colour for south and west-facing entrances. Glazed panels and side lights bring daylight into dark hallways, especially on north-facing elevations.
- Access and setting
- Rural doors often face open fields, driving rain and sometimes mud and animals, so robust weather seals and threshold drainage matter. Older cottages may have low or irregular openings, so doors are measured carefully and frames sized to suit.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Composite Doors in Barnet: questions
Are composite doors more secure than uPVC doors?
A well-specified composite door is usually stiffer and harder to force than an older uPVC panel door, but security depends mostly on the lock, cylinder, hinges and glass. Look for a multi-point lock, an anti-snap cylinder such as TS 007 3-star or SS312 Diamond, laminated glass and a door tested to PAS 24.
What glass can I have in a composite door?
Composite door glass comes in sealed cassettes with clear, obscure, bevelled, leaded-effect or decorative designs. Any glass within 1500mm of the floor in a door should be safety glass, and laminated glass adds security because it stays together when struck. Obscure designs give privacy in hallways while still letting daylight in.
What guarantee comes with a composite door?
Manufacturer guarantees apply to the door slab, frame, glass and locking hardware, and the terms are confirmed in writing. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered before you go ahead. Keep the paperwork with your building regulations certificate for when you sell the property.
Do I need planning permission to replace my front door?
In England, replacing a house's front door with one of similar appearance usually does not need planning permission. Listed buildings need listed building consent for significant works, and conservation areas or Article 4 directions can restrict changes to front doors, colours and materials. Flats may need permission, so check with your council if your home falls into any of these.
