A replacement front or back door is a new door and frame, usually composite, uPVC or aluminium, made to fit your existing opening and fitted with multi-point locks and weather seals to improve security, warmth and kerb appeal.
Whatever type of house you own in Belfast, we start by looking at how a new front or back door would fit it rather than offering a standard package. We cover BT1, BT2, BT6 and BT7 and neighbouring places such as Castlereagh, Newtownabbey and Lisburn. One named person looks after you from survey to handover, and nothing is booked until you hold our figure in writing, fixed for the work described.

Local housing and a new front or back door
Belfast has long rows of red-brick Victorian terraces, Edwardian villas in the north and south of the city and large post-war estates, while towns such as Ballymena, Antrim, Larne and Carrickfergus mix terraces, semis and newer developments. Dark basalt appears in older rural buildings, and pebbledash or roughcast is a very common finish.
Terraces suit loft conversions and rear extensions, and many need window and roof renewal. Pebbledashed homes commonly need re-rendering, and detached rural houses often take extensions, porches and driveways.
That variety is why a guide price for a new front or back door in Belfast is only a starting point; the survey shows what your particular property needs.
Planning and building rules in Belfast
Because Belfast falls under Northern Ireland's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
In Northern Ireland, like-for-like replacement windows and doors on a house rarely need planning permission. Listed buildings and conservation areas are the main exceptions, so check with the council before changing style or material.
The Building Regulations (Northern Ireland) apply to replacement windows, so the work needs building control approval or sign-off through an approved competent person route.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
We look at the job
A free survey comes first. It gives us what we need to price a new front or back door properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Written quote
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a new front or back door.
Getting ready
Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.
The work itself
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
How we work
Front and back doors in Belfast: questions
How long will my home be open while the door is fitted?
Fitting a new door usually takes half a day to a full day, and your home is only open for the short time between taking out the old frame and fixing the new one. We keep the opening covered if there is any delay, and we never leave a doorway insecure overnight. Once the frame is fixed, we hang the door, adjust the locks, seal around the frame and finish the trims.
How much will a new front or back door cost in Belfast?
As a guide, expect to pay £850–£3,000 including VAT for a new front or back door in Belfast. That range is adjusted for Northern Ireland, which runs about 14% below the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
How much does a new front door cost?
A new front door costs £850–£3,000 supplied and fitted, depending on the material, the amount of glass and whether you want side panels. A uPVC back door sits at the lower end, a composite front door in the middle, and aluminium doors or doors with side panels at the top. Locks, letterplates and dual colours also affect the figure. We confirm a fixed price in writing after measuring your opening.
How secure are modern doors?
Modern external doors are far more secure than older designs because they lock at several points along the frame, not just at the handle. We fit anti-snap cylinders, which resist a common method of forced entry, in reinforced frames. Laminated or toughened glass panels add further protection. For extra peace of mind you can add a door chain, a viewer or a smart lock, which we can include in your quote.
How long will a new front or back door take?
On a typical home, allow Usually half a day to one day per door. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
