## Noise Is the Door’s Language

A healthy automatic door makes one sound: a soft, even glide. Everything else is information. Because each mechanical fault has its own voice, the noise your door makes points surprisingly accurately at the failing part — and at how urgently it needs

.

**Grinding or scraping** is roller and track trouble. Worn roller bearings stop rolling and start dragging, or grit in the guide track is being ground under the leaf. This one compounds fast: every cycle wears the track further, so grinding is the noise to act on quickest — usually a

 job.

**Squealing or slapping** is the tooth belt. A loose belt slips against its pulleys; a worn one frays and clicks. Belt tension is a simple service adjustment, but ignored belts snap.

**Humming or buzzing with laboured movement** points at the motor working too hard — often because dragging rollers are loading it, sometimes because the motor itself is tiring.

**Rattling or knocking** suggests loose hardware: hanger brackets, cover panels or a guide out of alignment.

## Why Noise Deserves Fast Attention

| Noise | Likely part | Urgency |
| --- | --- | --- |
| Grinding | Rollers / track | High — self-accelerating wear |
| Squeal / slap | Drive belt | Medium — fails suddenly if ignored |
| Hum + slow movement | Motor under load | High — motor life at stake |
| Rattle / knock | Loose fittings | Low — but tighten before it grows |

The economics are blunt. A noisy door caught early needs rollers, a belt adjustment or lubrication — modest, single-visit work. The same door six months later can need a track, a motor and an emergency call-out. Noise is the cheap window.

## Getting It Quiet Again

Most noisy doors are fully recoverable with servicing: roller replacement, belt tension or renewal, track cleaning and alignment, and proper lubrication — all standard scope for our repair team, on any brand. Replacement talk only starts when motor, rollers and track are all worn together on an aged system — our guide on

 walks that judgement in detail.

Record ten seconds of the noise on your phone and WhatsApp it to us with your location. A technician can usually name the failing part from the audio alone, arrive with it in the van, and give your entrance its silence back in one visit.

## Frequently Asked Questions

Why is my automatic door grinding?

Grinding almost always means worn rollers or debris in the track — metal or grit being dragged instead of rolled. It's the most common noise fault and the most urgent, because grinding accelerates its own damage.

Is a squeaking or slapping belt serious?

A loose or worn tooth belt should be adjusted or replaced promptly. Left alone it slips, shock-loads the drive and eventually snaps — turning a cheap fix into a stranded door.

Can a noisy door be fixed without replacement?

Usually yes. Servicing the rollers, belt, track and lubrication resolves most noise. Replacement only enters the conversation when multiple core components are worn at once.
