About composite doors in Chiswick
In England, if the main entrance door of a home built in 1999 or later has a level threshold, the replacement should keep it level. Making access worse than when the house was built would not comply with the Building Regulations, so the glazier checks the existing threshold and specifies a low-threshold frame where needed.
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.
Glass in a door, and in any side panel within 300mm of the door's edge, counts as a critical location when it is within 1500mm of the floor. In England, Approved Document K expects that glass to be safety glass that breaks safely, such as toughened or laminated glass.
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.

About Chiswick for this job
- Postcodes covered
- W4, W3, W6 and the surrounding area, including Acton, Barnes and Hammersmith
- Coast
- Chiswick is well inland, around 44 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Chiswick 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 Chiswick: questions
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.
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.
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.
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.
