Coverage across County Londonderry
Wherever you are in County Londonderry, we need the same three things to get started on telescopic sliding doors: a short description of the door, a few photos if you have them, and the address. From there we agree the price in writing and book a specialist engineer working under our management. Every town listed below has a page of its own, 4 in total.

What to think about for telescopic sliding doors in County Londonderry
- Grit and leaves blown into the threshold collect in floor guide channels. Entrances facing a car park or open ground benefit from a matwell or canopy, which also keeps rain off the sensors.
- Entrances used by ambulances and patient transport in County Londonderry benefit from a full-opening button for crews, while everyday visitors use a narrower partial opening that keeps the waiting area warmer.
- Floor guides on two sets of leaves need a level, firm floor. Cracked screed, rocking tiles or a sloping threshold should be put right before fitting, and the quote will say who does it.
- Hospital and supermarket entrances in County Londonderry that run for long hours put more wear on the extra rollers and belts of a telescopic door. Plan a servicing arrangement from the start rather than waiting for the first fault.
- Shop units in County Londonderry that trade late or open early may want installation outside trading hours. Early starts and weekend work can usually be arranged and are shown as a separate line in the quote.

Standards and rules in Northern Ireland
The Building Regulations (Northern Ireland) 2012 require a powered door to have a means to prevent it trapping anyone and a means to open it if the power fails. Guidance on access to buildings is in Technical Booklet R, and building control approval is needed for new entrances.
In Northern Ireland machinery, including a new or converted powered door, carries the CE marking (with UKNI added where a UK body carried out the conformity assessment), and the EU Machinery Regulation applies there from 20 January 2027. Workplace law (the Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993) expects powered doors to have suitable and effective features to stop them trapping anyone and, where needed for safety, to open by hand unless they open automatically if the power fails. Doors at work must also be kept in efficient working order under a suitable system of maintenance.
In Northern Ireland, disability access duties come from the Disability Discrimination Act 1995, because the Equality Act 2010 does not apply there. Service providers and employers are expected to make reasonable adjustments, and an automatic door is a common one at entrances. New entrances and some alterations need building control approval in Northern Ireland, so check with your council’s building control before the work is ordered.
How it works
- Tell us about the entrance. Send the address, a few photos and a rough size of the opening, and say how the door is used. That is enough for us to suggest options for telescopic sliding doors and book a survey in County Londonderry.
- Free site survey. A specialist engineer working under our management measures the opening, checks the frame, floor, head height and power, and talks through how people use the entrance. There is no charge and no obligation.
- Fixed written quote. You receive a fixed, itemised written quote with the specification, lead time, payment stages and warranty terms. The price does not change unless the scope does, and any change is agreed in writing first.
- Installation and handover. The door is fitted on the agreed dates, then set up, tested and documented with reference to BS EN 16005. You are shown the controls and the simple checks to make, and receive the handover paperwork.

Telescopic sliding doors in County Londonderry: questions
Can you look after the door in County Londonderry once it is installed?
Yes. We can quote planned servicing for the new door, with each visit priced in writing beforehand and the interval set by how heavily the door is used and the manufacturer's instructions. Busy entrances such as hospitals and supermarkets are usually serviced more often than quieter offices.
What do you charge for telescopic sliding doors in County Londonderry?
Our guide starts from £6,995 excluding VAT (per door set), the same guide price we use across the UK. The free site survey in County Londonderry confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
How much wider will our entrance in County Londonderry be with telescopic doors?
As a rough guide, a telescopic door gives about two-thirds of its overall width as clear opening, against about half for a standard sliding door. On a typical shop or surgery entrance that can mean an extra 300 to 600 mm. The survey drawing for your building in County Londonderry shows the exact clear width before you commit.
Will a telescopic door in County Londonderry work with our fire alarm?
It can. The operator can take a signal from the fire alarm panel so the door opens and stays open, or does whatever the fire strategy for the building requires. The panel connection is usually made by your alarm engineer, and the quote shows who is responsible for each part of the work.
What does the free site survey in County Londonderry involve?
An engineer working under our management visits the building, measures the opening, checks the frame, floor, head height and power supply, and looks at how people use the entrance. The survey is free and carries no obligation. Afterwards you receive a fixed, itemised written quote for telescopic sliding doors, with drawings where the door type needs them.
Will the building stay secure while the entrance is being changed?
We plan to keep the entrance usable or secure throughout. Where a door has to come out, the work is sequenced so the opening is closed up before the engineer leaves, or a temporary door or hoarding is arranged when a longer gap cannot be avoided. How this is handled for your site in County Londonderry is agreed before work starts.
What do the building regulations in Northern Ireland say about powered doors?
The Building Regulations (Northern Ireland) 2012 require a powered door to have a means to prevent it trapping anyone and a means to open it if the power fails. Guidance on access is in Technical Booklet R, and new entrances need building control approval.
