Covering Alexandria and nearby
Addresses anywhere in the G83 postcode district can book drive unit replacement through us. The engineer who attends works under our management and travels to the site. There is no branch in Alexandria, so the price, the booking and the paperwork all come from one place.
Doors at quieter sites in Alexandria and elsewhere in Dunbartonshire can go many years between checks. A safety inspection looks at how the sensors, closing behaviour and emergency functions are working, and gives you a written record to keep on file.
Nearby towns we also list for drive unit replacement (straight-line distance): Dumbarton (3.5 miles), Helensburgh (5.5 miles), Erskine (8.3 miles).
What to think about for drive unit replacement in Alexandria
- Business parks and office blocks in Alexandria with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- Battery backup is easier to add with a new drive unit. It lets the door open or close safely in a power cut, which matters most on escape routes.
- Listed buildings and conservation areas in Alexandria make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.
- Check the power supply. A dedicated fused spur and isolator near the door is usually needed, and older installations sometimes need electrical work before the new operator goes in.
- Doors linked to the fire alarm or access control in Alexandria need those links rewired to the new controller. Let us know which systems connect to the door.

Standards and rules in Scotland
Standards are not retrospective, so an older door does not become unlawful when a standard is updated; a site-specific risk assessment shows whether any upgrades are sensible. BS EN 16005 is the current standard for the safety in use of powered pedestrian doors, and BS 7036-0:2014 is the British code of practice for risk assessment and risk reduction used alongside it. Standards are not law in themselves, but they are the recognised benchmark for showing an automatic door is safe to use, and we set up, test and document doors with reference to them.
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 drive unit replacement in Alexandria, 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.
Keep the frame, replace the drive. Arrange a free survey in Alexandria and receive a fixed quote covering the new operator, sensors and paperwork.
Drive unit replacement in Alexandria: questions
What lead time should we expect in Alexandria?
Once the quote is accepted, drive units are typically 2 to 4 weeks to arrive, depending on the length and weight rating needed. The changeover date is agreed with you as soon as the parts are confirmed, and it can be planned around your opening hours.
How much should I budget for drive unit replacement in Alexandria?
Our guide is £1,995 to £3,995 excluding VAT (per door), the same guide prices we use across the UK. The free site survey in Alexandria confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
How long will our entrance in Alexandria be closed for the changeover?
A standard sliding door changeover typically takes a day, and a swing operator often less. The work can be scheduled early, after closing or at a weekend so it causes less disruption. Your quote shows the planned date and how long the entrance will be out of use.
What if the frame of our door in Alexandria is not worth keeping?
Then we will tell you. Damaged or corroded frames, glass that is not safety glass, or an opening that is too narrow for the people using it are all reasons to choose a new door instead. We can quote both options so you can compare them side by side.
What should I send before the survey in Alexandria?
A few photos of the door from inside and outside, rough measurements of the opening, the address and a note of how the entrance is used. If the door already has an operator, a photo of any label on it helps. With that, the engineer arrives prepared, the survey takes less of your time and we can put the quote for drive unit replacement together more easily.
What does the written quote for drive unit replacement in Alexandria include?
The quote lists each item separately: the door or equipment, installation, electrical connections where we provide them, removal of anything being replaced, testing and handover. It is a fixed price for the work described, so it does not change unless the scope changes, and any change is agreed with you in writing first.
Who is responsible for automatic doors on escape routes in Alexandria?
The person responsible for fire safety under the Fire (Scotland) Act 2005 for those premises. Scottish guidance allows automatic doors on escape routes only where they fail safely to outward opening or have a monitored fail-safe system that opens them on power failure, sensor failure and fire alarm.
