Farnham: replacement front door
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, 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.
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.
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.
Included as standard
- Multi-point lock with anti-snap cylinder

- Survey, measuring and threshold check
- Removal and disposal of the old door and frame

Working in Farnham
- Postcodes covered
- GU9, GU10 and the surrounding area, including Aldershot, Fleet and Farnborough
- Coast
- Farnham is well inland, around 42 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Farnham 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.
Choosing your composite doors
Insulated foam core
A lighter slab with a high-density foam core, offering good thermal performance and a wide range of styles.
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.
Hardware finishes
Handles, knockers, letterplates and numerals in chrome, satin, gold, black or graphite, chosen to match the door style.
Composite Doors in Farnham: 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.
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.
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.
