Quick answer
Motor replacement in Gwynedd starts with a chargeable diagnostic visit, then a written fixed price for the new drive and any other repairs the door needs before it goes back into use.

- Guide price

What our engineers check and fix
- Brake and override. The new drive holds the door securely and can still be opened by hand in a power cut.
- Matched drives. Each replacement drive is selected for the door it will move, not just the old part number.
- Fault diagnosis. Diagnosis comes first, so you only pay for the parts the door actually needs.
- Force testing. Closing forces measured to BS EN 12453 where the door closes under power.
- Re-commissioning. The door is fully re-commissioned and tested before it goes back into use.
What this work can involve
- Fitting a centre-mounted motor where an end-mounted replacement would clash with racking beside the door.
- Fitting an equivalent chain-drive motor with adapter plates to a large sectional door whose original drive is discontinued.
- Diagnosing a stalling roller shutter to confirm whether the motor, a broken spring or the control panel is at fault.
Who is responsible for door safety at a site in Gwynedd?
In Wales, 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.
Planning the work around your site
Testing and repairs can mean closing an opening, so we agree timing and access with you before the visit, including early, late or weekend slots where the site needs them.

Your questions about industrial door motor replacement
Will our door in Gwynedd 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 Gwynedd?
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 Gwynedd?
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.
