NW Automatic Doors repairs commercial sectional overhead doors across North Wales — the insulated panelled doors used on units, workshops and warehouses. Our engineers fix broken torsion springs, snapped cables, worn rollers and tracks, dented panels and failed automation, usually the same day, with 24/7 emergency cover when a sectional door is stuck and locking up your unit.

Urgent and non-urgent routes are kept separate, so a site-down call can stay focused on getting safe and operational.

A broken spring is more than an inconvenience

The springs on a sectional door hold huge tension — when one snaps, the door becomes heavy, dangerous to move and often jams halfway, leaving your unit open or shut. This isn’t a safe DIY fix. Our engineers replace springs and cables as a matched set, service the rollers and tracks and re-balance the door so it runs smoothly. We carry common parts to fix most sectional doors on the first visit.

Getting your unit secure again

  1. Call us with the door size and what’s failed.
  2. We aim to attend the same day and make the door safe.
  3. We replace springs, cables or rollers and re-balance the door.
  4. We test the door and opener and price any extras up front.

Before you approve the repair

Clear fault finding before parts, replacement or contract spend

Commercial buyers need the opening safe, the fault understood and the next step priced clearly. We make the site safe first, diagnose the root cause, and explain whether repair, replacement or maintenance is the honest route.

Make-safe first We secure, isolate or free the opening before deeper repair work starts.
Repair before replacement Viable faults are repaired; replacement is only recommended when repair stops making sense.

Planned follow-up If the same fault is likely to return, we explain the maintenance visit that prevents it.

Answers

Frequently asked questions

Can you replace a broken sectional door spring in Mold or Flint?

Yes. A snapped torsion spring is the most common sectional door failure, and we replace them across Mold, Flint and all of North Wales, usually the same day. Springs are high-tension and unsafe to fix without the right tools, so our engineers carry common sizes for a first-visit repair.

Is it safe to keep using a door with a broken spring?

No — you shouldn’t. With a broken spring the door is heavy, can drop suddenly and often jams part-way, leaving your unit insecure. Stop using it and call us; we’ll aim to attend the same day, make the door safe and replace the springs and cables as a matched set.

Do you repair the electric opener as well as the door?

We do. We repair and replace sectional door operators, motors, control boards and remotes, and fix the safety photocells that stop the door closing on a vehicle or person. We’ll also re-balance the door itself, because a poorly balanced door wears the opener out early.

Can you replace a single panel if it’s damaged?

Usually, yes. Individual insulated panels can often be replaced rather than the whole door, which keeps costs down. Where a door is genuinely beyond economical repair we’ll say so and quote a like-for-like replacement — and any quote you already hold gets a free, no-obligation second opinion.

How quickly can you attend a stuck sectional door?

We aim for same-day attendance across North Wales and run a 24/7 emergency line, because a sectional door stuck open leaves your unit exposed. Our in-house engineers — not subcontractors — are rated a perfect 5.0★ on Google and carry common springs, cables and rollers for first-visit fixes.
