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.
Anyone planning bifold or sliding doors in Cookstown wants three things: a clear price, a realistic timetable and a tidy job. We publish a guide of £2,600–£6,900 including VAT for Northern Ireland up front, explain that work normally takes 1–2 days to fit into a ready opening, and confirm both in writing after a free survey of your property.

Building in Cookstown
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.
Whatever era your Cookstown home dates from, we plan bifold or sliding doors around how it is actually built rather than a one-size-fits-all specification.
Do you need permission in Cookstown?
For anyone in Cookstown, the relevant framework is Northern Ireland's. The summary below is general, so we always contact the council about your address before putting a price in writing.
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.
The four stages
A visit to your home
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about bifold or sliding doors.
Written quote
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Plan and prepare
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for bifold or sliding doors are in place before the first day on site.
On site to finish
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
Why homeowners choose us
Common questions
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.
Should I choose bifold or sliding doors?
Bifold doors suit you if you want to open the whole width to the garden, because the panels fold and stack to one side. Sliding doors suit you if you mainly want the view, because they have fewer, larger panes and slimmer frames, though only part of the width opens. Sliding doors also take up no room when open. We help you weigh up how you will use the space in summer and winter.
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.
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.
Can you combine bifold or sliding doors with other work?
Yes. Because we manage several trades under one contract, we can plan bifold or sliding doors alongside other work on your Cookstown home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
