Replacement front door across Belfast
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.
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.
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.

- Coast
- Belfast is about 1 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. 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.
- Daylight and sun
- In Belfast the midwinter sun reaches about 12° above the horizon at noon, with roughly 7.0 hours of daylight, rising to about 59° and 17.0 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
- Street-facing front doors in towns and cities face more passers-by, so anti-snap cylinders, laminated glass and letterplate guards are worth specifying. Conservation areas may control front door styles and colours, and flat entrance doors onto shared corridors normally need fire-rated doorsets.
- Rules in Northern Ireland
- Technical Booklet V covers safety glazing in Northern Ireland, including glass in and around doors and low-level glazing where people could walk into it.

In Northern Ireland, replacing windows and doors in an existing home does not usually need a building control application, but the work must still meet the Building Regulations (Northern Ireland), including the energy and safety glazing requirements. Other buildings, new openings and structural changes can need approval, so check with the council's building control if you are unsure. Replacing only the glass in an existing frame is a repair.

Composite Doors in Belfast: 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.
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.
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.
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.
