Bifold doors are glazed panels that fold and stack to one side to open up a wide gap, while sliding doors glide past each other on tracks; both connect a living space to the garden and bring in more daylight.
In County Armagh, we price bifold or sliding doors against our guide for Northern Ireland, £2,600–£6,900 including VAT, then adjust it once we have surveyed your home. We work across Craigavon, Portadown and Armagh and the rest of the county or region. Planning and building control requirements follow the rules for Northern Ireland, and we look into your property's position before a written quote is sent.

Homes in County Armagh
Armagh city has Georgian buildings, many in local limestone, around its historic centre. Portadown and Lurgan, linked by the Craigavon plan of the 1960s, have Victorian terraces, post-war estates and newer developments. The countryside is dotted with detached rural houses and bungalows, often finished in roughcast or render.
Rural bungalows and detached homes commonly take extensions, loft rooms, driveways and fencing. Terraces suit rear extensions and window replacement, and rendered houses often need re-rendering or painting.
A moderate inland climate with frequent rain and winter frost, and low ground near Lough Neagh can be wet.
Planning and building rules in County Armagh
County Armagh is in Northern Ireland, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
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.

Questions about bifold or sliding doors in County Armagh
How much do bifold doors cost?
Bifold doors cost £2,600–£6,900 for a typical 3m opening, supplied and fitted. As a rough guide, allow around £900–£2,000 per metre of width plus the fixed costs of fitting, depending on frame material and glass. uPVC sits at the lower end and slimline aluminium at the top. Widening the opening with a new steel adds to the price. We confirm a fixed figure after measuring.
How long do bifold doors take to make and fit?
Aluminium bifold and sliding doors usually take several weeks to manufacture after the survey, depending on the supplier and colour. Fitting into a ready opening normally takes one to two days, including sealing and finishing trims. If we are widening the opening, allow a few extra days for the structural work and making good before the doors arrive. We give you the expected timeline with your quote.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
Can you fit bifold doors where I have a window now?
Bifold doors can usually replace a window by cutting the wall down to floor level and, if the opening is being widened, fitting a new lintel or steel beam. A structural engineer sizes the beam, and building control approval is needed. Radiators, pipes and cables under the window may need moving. We check all of this at the survey and include it in a single written quote.
How long will bifold or sliding doors take?
On a typical home, allow 1–2 days to fit into a ready opening. 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.
