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 Tyrone, 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 Omagh, Strabane, Dungannon and Cookstown 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.

Housing across County Tyrone
Tyrone is largely rural, with detached houses and bungalows on individual plots across the countryside, many finished in render or roughcast. Omagh, Dungannon, Cookstown and Strabane have Victorian terraced streets, post-war estates and newer developments, and stone farmhouses survive in older rural areas.
Rural detached homes commonly take extensions, loft rooms, porches and driveways, and older houses may need re-roofing and re-rendering. Town terraces suit rear extensions and window replacement.
Wet and fairly cool, with upland exposure in the Sperrins and frost common through the winter months.
Planning and building rules in County Tyrone
The notes below cover Northern Ireland, which is where County Tyrone sits. Rules change and every property is different, so we speak to the council before pricing your job.
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 Tyrone
Do I need planning permission in County Tyrone?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. County Tyrone is in Northern Ireland, so Northern Ireland's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Can I have a level threshold?
A level threshold means the door track sits flush with the floor, so there is no step between inside and out. Most aluminium bifolds and sliders can be fitted this way, but the outside paving must sit just below the track with a drainage channel to keep rain out. Rebated thresholds give stronger weather protection with only a small step. We check floor and patio levels before recommending either.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
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 do I maintain bifold doors?
Bifold doors need simple, regular care to keep them running smoothly. Vacuum or brush grit out of the bottom track every few weeks, wipe the frames with warm soapy water and avoid abrasive cleaners. Once or twice a year, lubricate the rollers, hinges and locks with a silicone spray. If the panels start to drop or catch, the hinges can usually be adjusted rather than replaced.
