Commercial Overhead & Sectional Door Repair in DFW

A sectional overhead door is a stack of hinged panels that rolls up overhead on tracks, counterbalanced by a torsion or extension spring so a motor — or a person — can move a door that may weigh several hundred pounds. Almost every failure traces back to that system: a spring, a cable, a roller, a hinge, a track, or the opener that drives it. Knowing which one is acting up is most of the diagnosis.

Sound familiar?

These are the symptoms we route most often on sectional doors:

• You heard a loud bang from the shop, and now the door is far too heavy to lift or the opener strains and stops — a classic broken spring.
• The door hangs crooked, a panel has pulled out of the track, or a frayed cable is dangling on one side.
• The door reverses before it seats, won't stay down, or opens by itself — often a photo-eye, limit, or safety-reversal issue.
• It's loud, jerky, or slow: worn nylon or steel rollers, dry or bent hinges, or a track that's been clipped by a forklift.
• The opener hums but the door doesn't move, the chain or belt is loose, or the logic board is dead after a storm or power event.
• Bottom panel and weather seal are crushed or torn, letting in water, air, and pests along the floor line.

What a contractor will need to know

You don't need the manufacturer or model number — most facility managers don't have it, and a photo answers more than a spec sheet. What speeds up an accurate callback:

• Roughly how it operates: chain hoist, wall-mounted jackshaft operator, trolley opener, or fully manual.
• Approximate size and number of panels — "about 12 by 14, four sections" is plenty.
• Is it stuck open or stuck closed? That single answer decides whether it's a security problem tonight or a scheduled fix.
• Photos of the spring assembly above the door, the bottom bracket and cable, and the data plate if there is one. Sending photos is standard practice in this trade, not a burden.

The request form walks through exactly these questions, so the contractor who calls already has the picture.

Typical repair scenarios & what drives cost

We don't publish prices — a real number depends on the door and what a contractor finds on site, and any figure we invented would be misleading. What we can be honest about is what moves the cost:

• Spring vs. hardware vs. opener. A spring or cable replacement, a roller and hinge refresh, and an opener board swap are three different jobs with three different parts costs.
• Spring type and cycle rating. Torsion springs are rated in cycles; a high-cycle spring on a busy dock door costs more up front and lasts longer. Doors run in balanced pairs of springs — many technicians replace both so the second failure doesn't follow in weeks.
• Door size and weight. Bigger, insulated, or wind-rated doors carry heavier hardware and take longer.
• After-hours and emergency response. A door stuck open overnight is a same-night security call, and after-hours labor is commonly billed at a premium over standard rates.

Ask any contractor for a written estimate that separates parts, labor, and any trip or after-hours fee. Price opacity is a chronic complaint in this trade, and a clear breakdown is the simplest way to avoid a surprise invoice. Our guide to choosing a contractor covers what else to check.

A safety note before you touch it

The counterbalance springs on an overhead door store a large amount of energy under tension. DASMA — the trade association for the door industry — states plainly that spring replacement "should only be performed by a trained door systems technician," because a spring or winding bar under load can cause severe lacerations, broken bones, or worse. If a spring or cable is broken, don't try to force the door or lift it manually, and don't run the opener against it. If the door is stuck open and you need to secure the building tonight, read securing your building after hours first.
