Cornwall: secure front doors
A flat's entrance door that opens onto a shared stairwell or corridor is normally a fire door, so it should not be swapped for a standard composite door. Certified fire-rated composite doorsets are made for this purpose, and the freeholder or managing agent will usually need to agree the replacement.
Letterplates can be a security weak spot, because tools can be fed through to reach the inside handle or keys. A letterplate with an internal cowl or restrictor, or a door with no letterplate and a wall-mounted post box, reduces that risk. Keys should be kept away from the door.
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.
Most composite doors use a multi-point lock: one turn of the key throws hooks, rollers or bolts into keeps along the frame. The euro cylinder is the weak point on many older doors, so look for one tested against snapping, such as a TS 007 3-star kitemarked or Sold Secure SS312 Diamond cylinder.

What applies in Cornwall
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.
For shops and other non-domestic buildings in England, Approved Document M covers accessible entrances, and Approved Document K requires large areas of glass that people could walk into to carry manifestation (visible markings).
Cornwall has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Near the sea, salt air corrodes plated door furniture and lock parts more quickly, so marine-grade or stainless hardware is worth considering. Exposed doors also face wind-driven rain, so a well-sealed frame, weatherbar and threshold drainage matter more than usual.
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.

Choosing your composite doors
Solid timber core
A heavier slab with a timber core under the composite skin, giving a solid feel and sound when the door closes.
Low threshold
A low-profile aluminium threshold for step-free or near step-free access, used where drainage and shelter allow.
Colours and dual colour
Woodgrain-textured skins in many colours, often with a different colour inside so the door suits both the street and the hallway.
Glass designs
Clear, obscure, bevelled or decorative glass in sealed cassettes, with toughened or laminated panes for safety and security.
Composite Doors in Cornwall: questions
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.
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.
Can a composite door be fitted with a level threshold?
Yes, composite doors can be supplied with a low aluminium threshold for step-free or near step-free access. In England, where a house built in 1999 or later has a level threshold at the main entrance, the replacement should keep it. Low thresholds need good drainage and some shelter from driving rain, which the glazier checks at survey.
Do I need building regulations approval for a new front door?
It depends on the door and where you live. In England, replacing a glazed external door is notifiable building work and must meet the energy standard, while the position for a mostly solid door depends on how much of it is glazed. A competent person scheme installer can self-certify notifiable work; otherwise building control approves it. Wales, Scotland and Northern Ireland have their own systems, and we explain which applies before fitting.
