Industrial door motor replacement in Dorchester

In short

Replacing a door motor at a site in Dorchester is a chance to upgrade the control panel too, adding inverter control, remotes, loops or traffic lights at the same time.

Town: Dorchester
Postcode district: DT1
Area: Dorset
Guide price: £845 – £2,395

What's included

Re-commissioning. Limits set, cycles tested and safety devices checked before handover.
Obsolete motors. Equivalent drives with adapters where the original model is no longer made.
Fault diagnosis. Diagnosis comes first, so you only pay for the parts the door actually needs.
Force testing. Where it applies, we measure closing forces to confirm the door is safe after the change.
Panel upgrades. Older panels can be replaced at the same time for better reliability and safety.

What this work can involve

Replacing a motor with a slipping brake on a heavy shutter that creeps down from a part-open position.
Upgrading an old relay control panel to a modern unit with monitored safety edge inputs during a motor change.
Replacing a burnt-out direct-drive motor on a loading bay door and fitting an inverter control panel at the same time.

Who is responsible for door safety at a site in Dorchester?

In England, two sets of duties meet at a powered door. The installer who supplies or motorises it must hand over a door that meets the Supply of Machinery (Safety) Regulations 2008, tested against BS EN 12453 and documented. The business in control of the premises must then maintain it: regulation 5 of the Workplace Regulations 1992 covers maintenance, and regulation 18 requires upward-opening doors to have a device that stops them falling back and powered doors to have features that prevent trapping.

Keeping your site running during the work

Before work starts we send a method statement and risk assessment, confirm who on site will be our contact and agree where materials and access equipment will go. On shared industrial estates that can mean booking yard space with the landlord.

Frequently asked questions

Should we replace the whole door instead of the motor in Dorchester?

If the door itself is old, damaged or needs several other repairs, replacement can be better value. We price both where it makes sense, so you can weigh up the cost and remaining life honestly.

How soon can a door motor in Dorchester be replaced?

Many common motors can be sourced quickly, and fitting usually takes a few hours once the drive is on site. Specialist or obsolete motors may need ordering; we tell you the lead time with the quote.

Will our door in Dorchester be tested after the motor is changed?

Yes. We set limits, test the brake and manual override, check safety devices and measure closing forces where required, then give you a written record of the work and test results.
