Covering Harpenden and nearby
We cover the whole of the AL5 postcode district, along with nearby towns in Hertfordshire. You book each visit for telescopic sliding doors directly with us, and a specialist automatic door engineer working under our management travels to your site on the agreed date.
Libraries, health centres and council buildings in Harpenden still need accessible entrances, whatever their size. A single automatic door with a push pad or touch-free switch is often enough to give everyone easy access.
Nearby towns we also list for telescopic sliding doors (straight-line distance): St Albans (4.7 miles), Luton (5.0 miles), Hemel Hempstead (5.9 miles), Welwyn Garden City (6.5 miles), Hatfield (6.8 miles), Dunstable (8.5 miles).
What to think about for telescopic sliding doors in Harpenden
- A telescopic header is deeper than a standard one. In older buildings in Harpenden with low ceilings or decorative fanlights, the survey checks whether the header can sit above the opening or needs to be recessed.
- If the entrance is on an escape route, ask your fire risk assessor what the door must do before ordering. Break-out telescopic leaves have to be chosen at the start, because they cannot be added afterwards.
- Entrances used by ambulances and patient transport in Harpenden benefit from a full-opening button for crews, while everyday visitors use a narrower partial opening that keeps the waiting area warmer.
- Measure the widest thing that has to pass through, whether that is a hospital bed, a mobility scooter or a cage of stock. The clear opening of a telescopic door is chosen from that figure, not from the size of the old doorway.
- Hospital and supermarket entrances in Harpenden 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.

Standards and rules in England
Building regulations guidance in England (Approved Document M, Volume 2) says a powered opening system should be used where a self-closing entrance door would need more than 30 N at the leading edge to open, or more than 22.5 N between 30° and 60°, and expects external doors used by the public in new buildings to give at least 1000 mm of effective clear width.
In Great Britain a new or converted powered door must meet the Supply of Machinery (Safety) Regulations 2008 before it is first used, and can carry the UKCA or the CE marking. Workplace law (the Workplace (Health, Safety and Welfare) Regulations 1992) 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.
How it works
- Get in touch. Call, email or use the form with the address and what you have in mind. If you are not sure which type of door suits, describe the entrance and we will suggest the options worth considering.
- Survey and advice. The survey costs nothing and carries no obligation. The engineer checks the site and explains which options suit the entrance, the people using it and the budget, before anything is priced.
- Quote in writing. You receive a fixed, itemised quote for telescopic sliding doors in Harpenden, covering equipment, installation, testing and handover, with the lead time and payment stages set out clearly.
- Install, test, explain. The engineer installs and commissions the door, tests the sensors, safety functions and emergency behaviour, and walks you through the controls. The handover pack records what was installed and tested.

Telescopic sliding doors in Harpenden: questions
Will a telescopic door in Harpenden 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 do you charge for telescopic sliding doors in Harpenden?
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 Harpenden confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Can our existing sliding door in Harpenden be converted to telescopic?
Not usually by modifying the old door, because the header, tracks and leaves are different. It is normally replaced as a complete set within the same opening. The survey checks whether the existing structure and floor can take the new door, and the quote shows removal of the old one as a separate line.
Do we need to close our building in Harpenden while the door is fitted?
Usually not for long. Most telescopic entrances take one to two days on site, and the opening can be secured overnight. Where the entrance is the only way in, we plan the work around your hours, use another entrance if there is one, or work early or at weekends, with any extra cost shown in the quote.
Is there a warranty on telescopic sliding doors?
Yes. The warranty terms for the equipment and the installation are set out in your written quote, so you can see exactly what is covered before you accept. Keeping the door serviced at the recommended intervals helps keep it in good order, and the quote explains any conditions that apply to the warranty.
How do you make sure the door works for disabled visitors in Harpenden?
We look at who uses the entrance: wheelchair users, people with walking aids, parents with buggies and older visitors. That shapes the opening width, the opening speed, the hold-open time and where push pads or sensors go. Service providers and employers have duties to make reasonable adjustments under equality and accessibility law, and an automatic door is a common one.
Who is responsible for automatic doors on escape routes in Harpenden?
Under the Regulatory Reform (Fire Safety) Order 2005 the responsible person for the premises must make sure escape routes work and fire safety equipment is maintained. Automatic doors on an escape route need fail-safe opening or break-out, set by the fire strategy.
