How we look after doors in Harrow

Force testing. Where it applies, we measure closing forces to confirm the door is safe after the change.
Panel upgrades. New control panels with monitored safety inputs and inverter options.
Matched drives. Motor torque, speed and mounting matched to the door's weight and size.
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.

What this work can involve

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.
Upgrading an old relay control panel to a modern unit with monitored safety edge inputs during a motor change.

Safety law for industrial doors in England

Industrial doors in Harrow are covered by the same rules as the rest of Great Britain. On handover you should receive user instructions and, for a powered door, the conformity paperwork, because the installer is treated as the manufacturer when they assemble or motorise it. Afterwards, keeping the door in efficient working order is the occupier's job under the Workplace Regulations 1992 and PUWER 1998, which in practice means regular servicing and a written log.

Planning the work around your site

On a first visit we record each door's make, size, control type and condition. That record makes later repairs quicker to price and helps you plan replacements before a door fails.

Industrial door motor replacement in Harrow: your questions

Is the motor really the problem with our door in Harrow?

Not always. Broken springs, damaged guides, failed panels, safety device faults and supply problems can all look like a failed motor. We diagnose first so you do not pay for a motor that will not fix the fault.

Can you replace an obsolete door motor in Harrow?

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.

How much does an industrial door motor replacement cost in Harrow?

Our guide price for a replacement motor is £845 to £2,395 ex VAT, supplied and fitted, depending on door size, drive type and whether a new control panel is needed. A diagnostic repair visit in Harrow costs £145 to £195 ex VAT.
