Covering Windsor and nearby
Coverage for drive unit replacement runs across the SL4 postcode district and out into the surrounding parts of Berkshire. Wherever the building is, the arrangements stay the same: one contracting party, a written price before work, and a specialist engineer working under our management on site.
Doors at quieter sites in Windsor and elsewhere in Berkshire 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): Slough (1.8 miles), Egham (4.1 miles), Staines-upon-Thames (5.4 miles), Maidenhead (5.8 miles), Uxbridge (6.8 miles), Ashford (7.1 miles).
What to think about for drive unit replacement in Windsor
- If the door is on an escape route, the new drive unit must be set up to open, break out or be openable by hand, as the building's fire strategy requires.
- Busy retail entrances in Windsor may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.
- Doors linked to the fire alarm or access control in Windsor need those links rewired to the new controller. Let us know which systems connect to the door.
- Listed buildings and conservation areas in Windsor 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.

Standards and rules in England
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.
Whoever motorises a manual door, or builds an automatic door from separate parts, may take on the manufacturer’s legal duties for the finished door: a risk assessment, a technical file kept available for the authorities, a Declaration of Conformity, the conformity marking and instructions. You receive the Declaration of Conformity and the instructions at handover. 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.
How it works
- Send photos and the address. A few pictures of the door from both sides, the address in Windsor and a note of who uses the entrance help us understand the job before anyone visits the site.
- No-cost survey on site. We arrange a survey at a time that suits the building. The engineer records measurements, fixings and power, plus any constraints such as listed status, opening hours or access for deliveries.
- Itemised quote to approve. We price every element of the work on drive unit replacement separately in a written quote that you can check, share and approve. Lead time and payment stages are stated, and nothing is ordered until you accept.
- Fit, test and hand over. On the agreed dates the engineer installs the equipment, commissions the operator and tests each safety function. You get a demonstration, the test record and any conformity paperwork that applies to the work.

Drive unit replacement in Windsor: questions
What if the frame of our door in Windsor 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 is the guide price for drive unit replacement in Windsor?
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 Windsor confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Will you remove the old operator from our premises in Windsor?
Yes. The old drive unit, sensors and any other replaced parts are taken away as part of the job, and the work area is left clean. Disposal is included in the fixed quote, so there is nothing extra to arrange or pay for afterwards.
How long will our entrance in Windsor 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.
Is there a warranty on drive unit replacement?
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 much disruption should we expect while the work is done in Windsor?
Most installations take one visit or a short series of visits, with dust and noise kept to the area around the door. The engineer screens off the work area, keeps a route in or out where possible and clears up before leaving. Larger entrances, lobbies or structural changes take longer, and the quote explains how that work is phased.
Who is responsible for automatic doors on escape routes in Windsor?
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.
