How we look after doors in Trowbridge

Fault diagnosis. Diagnosis comes first, so you only pay for the parts the door actually needs.
Written records. A record of the work and tests for your maintenance file.
Matched drives. Motor torque, speed and mounting matched to the door's weight and size.
Re-commissioning. The door is fully re-commissioned and tested before it goes back into use.
Brake and override. The new drive holds the door securely and can still be opened by hand in a power cut.

Examples of work we can quote for

Upgrading an old relay control panel to a modern unit with monitored safety edge inputs during a motor change.
Replacing a motor with a slipping brake on a heavy shutter that creeps down from a part-open position.
Changing a tubular motor in a small service shutter that overheats and trips during busy periods.

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

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

How soon can a door motor in Trowbridge 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 Trowbridge 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.

Can you replace an obsolete door motor in Trowbridge?

Yes. Where the original is no longer made, we fit an equivalent drive with any adapter plates or couplings needed, then set limits and test the safety devices before the door goes back into use.
