Dunstable: replacement front door
Replacing a front door usually takes a day on site. The old door and frame are cut out, the new frame is fixed, packed and squared, the slab is hung and adjusted, and the frame is sealed outside and trimmed inside. Plaster around older frames sometimes needs making good afterwards.
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.
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 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.
What a typical job includes
- Survey, measuring and threshold check
- Removal and disposal of the old door and frame
- Made-to-measure composite doorset in your chosen colour
- Multi-point lock with anti-snap cylinder

Local details for Dunstable
- Postcodes covered
- LU6 and the surrounding area, including Luton, Leighton Buzzard and Harpenden
- Coast
- Dunstable is well inland, around 78 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Dunstable the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 62° and 16.5 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
Hardware finishes
Handles, knockers, letterplates and numerals in chrome, satin, gold, black or graphite, chosen to match the door style.
Side panels and toplights
Glazed or solid panels beside or above the door to bring light into the hallway and fill wider openings.
Solid timber core
A heavier slab with a timber core under the composite skin, giving a solid feel and sound when the door closes.
Composite Doors in Dunstable: 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.
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.
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.
