Composite back doors in Sevenoaks
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.
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.
In England, Approved Document L sets the limiting standard for a new door in an existing home at a U-value of 1.4 W/m²K, or a Doorset Energy Rating of band B for a mostly solid door. Doors with more than 60% of the face glazed may instead meet band C.

- Coast
- Sevenoaks is well inland, around 23 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Sevenoaks 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.

In England, replacing a whole window, roof window or glazed external door is building work. It has to be notified to building control, either by an installer registered with a competent person scheme such as FENSA or Certass, or through a building notice to the council. Replacing only the glass in an existing frame is a repair and is not notifiable.
Options to choose between
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.
Solid timber core
A heavier slab with a timber core under the composite skin, giving a solid feel and sound when the door closes.
Hardware finishes
Handles, knockers, letterplates and numerals in chrome, satin, gold, black or graphite, chosen to match the door style.
Composite Doors in Sevenoaks: questions
How much does a composite front door cost?
The cost of a composite door depends on the style, core type, colour, glass, side panels or toplights, hardware and lock specification, plus the condition of the opening. A plain door in a standard colour sits at the lower end, while doors with glazed side panels and premium hardware cost more. See the guide prices; the written quote fixes your price.
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.
Can I change a flat's front door to a composite door?
It depends where the door is. A flat entrance door that opens onto a shared stairwell or corridor is normally a fire door, so only a certified fire-rated doorset is suitable. Leaseholders usually need the freeholder's or managing agent's agreement too. A flat door opening directly outside may be treated like a house door, so check first.
How long does it take to fit a composite door?
Fitting a composite front or back door usually takes a day on site, including removing the old door and frame, fitting and adjusting the new doorset and sealing around it. Doors are made to order first, and the manufacturing lead time depends on the style and colour; it is confirmed in writing when you accept the quote.
