Industrial door motor replacement in Carshalton

The short version

Door stalling, grinding or creeping down at your Carshalton site? It may need a new motor, or the motor may be suffering from a fault elsewhere. We diagnose which it is before recommending anything.

Town: Carshalton
Postcode district: SM5
Area: Greater London
Guide price: £845 – £2,395

What our engineers check and fix

Written records. You receive written details of the new drive and test results for your records.
Re-commissioning. Limits set, cycles tested and safety devices checked before handover.
Force testing. Where it applies, we measure closing forces to confirm the door is safe after the change.
Fault diagnosis. Diagnosis comes first, so you only pay for the parts the door actually needs.
Brake and override. The new drive holds the door securely and can still be opened by hand in a power cut.

Jobs we can carry out

Changing a tubular motor in a small service shutter that overheats and trips during busy periods.
Fitting a centre-mounted motor where an end-mounted replacement would clash with racking beside the door.
Diagnosing a stalling roller shutter to confirm whether the motor, a broken spring or the control panel is at fault.

Powered door rules that apply in Carshalton

Carshalton is in England, where powered industrial doors fall under Great Britain's health and safety law. Whoever makes a door powered — including converting a manual door — usually takes on the manufacturer's duties under the Supply of Machinery (Safety) Regulations 2008: risk assessment, technical file, conformity marking and a Declaration of Conformity. Once it is in use, the employer or occupier must keep it safe under the Workplace (Health, Safety and Welfare) Regulations 1992 and PUWER 1998.

How the work is organised

Service and repair visits in Carshalton are booked around your shifts. Doors and shutters are taken out of use one at a time, so the rest of the site keeps working while each one is checked.

Frequently asked questions

Can you replace an obsolete door motor in Carshalton?

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.

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

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.

Will our door in Carshalton 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.
