Commercial Sectional Door Repair
The sectional overhead door is the one you picture when you think 'garage door,' just scaled way up for a warehouse, a shop bay, or a loading dock — insulated steel panels stacked on a track, running dozens of times a day instead of a few times like a house door. That heavier duty is the whole point, and it's also why they fail harder. Everything on a commercial sectional is beefed up: thicker torsion springs, heavier aircraft-grade cable, wind-load struts across the panels, and commercial-grade hinges and rollers. When one of those lets go on a busy dock, the door's dead in the opening and your shipping line stops cold. That downtime is money, and getting you back in service fast is the whole reason we run a commercial crew.
Nick Gharivand founded Trusty in 2020 after more than ten years turning wrenches, and commercial sectional doors are bread-and-butter work for us across DFW. The tech we send is one of ours — in-house, background-checked, on our payroll, never a subcontractor we found that morning. He'll diagnose the real failure, size the replacement parts to your specific door and its cycle demands instead of grabbing whatever's cheapest, and give you the price in plain English before any work starts. Parts and labor are warranty-backed, we work around your business hours to keep the disruption down, and we run 24/7 for the emergencies that can't wait till morning. Call (214) 624-6348.
Why It Matters
A commercial sectional door isn't just a big residential door — it's engineered for a duty cycle a house door never sees. A home door might run 1,500 cycles a year; a busy dock or shop door can run that in a month, so the springs, cables, and hardware are all sized heavier and rated for far more cycles. The torsion springs are wound from thicker wire and often spec'd high-cycle — 25,000 to 100,000 cycles — because a standard 10,000-cycle spring would burn through in months. The lift cables are heavier aircraft-grade wire, and the panels usually carry horizontal struts to keep them from bowing under their own width and wind load. When a high-cycle spring snaps, that door drops a couple hundred pounds of insulated steel into the opening — dangerous, and it strands the bay. And because everything cycles so hard, one worn part cascades: a tired spring overworks the operator, a frayed cable throws the door crooked and drags it on the track, a shot roller or hinge lets a panel rack out of square. The heat and grit out here only speed that wear along. Staying ahead of it is the cheapest way to avoid an emergency that stops your operation cold.
Signs You Need Commercial Sectional Door Repair
- A loud bang from the bay and now the door's dead-heavy or won't lift — almost always a broken torsion spring, and on a commercial door it's a heavy one.
- The door racks crooked, one side climbing higher than the other, which points to a snapped cable or a failed spring on that side.
- A panel's bowing, cracked, or pulling apart at the hinges, or a strut's come loose.
- Frayed aircraft cable, a cable piled loose in the track, or a cable that's jumped off the drum.
- The door binds, drags, or shudders on the heavier 2- or 3-inch commercial track, or the rollers are grinding and wobbling.
- The door won't seal at the floor, cycles slower than it used to, or the operator's straining on every lift.
How We Do It
- We start with a full safety check of the whole door — springs, cables, drums, rollers, hinges, struts, track, and balance — because on a hard-cycled commercial door one failure usually has a worn partner right behind it.
- We diagnose the real cause and size the replacement parts to your door's weight and cycle demand — high-cycle torsion springs, heavier-gauge cable, commercial hinges and rollers — not whatever's cheapest on the shelf.
- You get the price up front, plain and in writing, before any wrench turns, and we schedule around your business hours wherever we can to keep your operation moving.
- We make the repair with the door properly secured and the tension safely controlled — replacing springs in matched pairs, cables in pairs, and any racked hinges, rollers, or struts.
- Then we re-tension, rebalance, and cycle the door, test the operator and the safety reversing, and walk you through the warranty before we clear the bay.
What Affects the Price
- What failed and the part grade. A high-cycle commercial torsion spring or aircraft cable costs more than the residential equivalent, but it's rated for the duty your door actually sees.
- The size and weight of the door. A big insulated dock door runs heavier springs, thicker cable, and more hardware than a small shop bay.
- The cycle rating you go with. High-cycle springs cost more up front but last far longer on a door that runs all day — usually the smarter spend on a busy bay.
- Whether anything cascaded from the first failure — bent track, racked panels, damaged struts, or worn drums and rollers riding along with it.
- A standard same-day visit versus a 24/7 emergency to get a downed bay running overnight. For an actual number, call (214) 624-6348 and we'll talk it through.

I had a great experience with Taylor T. from Trusty Garage Door Repair. He was professional, punctual, and clearly very knowledgeable. He thoroughly explained the issue and walked me through the repair step by step, which gave me a lot of confidence. He even offered practical guidance on maintaining my door to prevent future problems. Absolutely recommend.
Frequently Asked Questions
How's a commercial sectional door different from a residential one?＋
It's built for way more work. A house door might cycle a few times a day; a commercial dock or shop door can run dozens of times a day, so everything's heavier-duty — thicker torsion springs (often high-cycle rated), heavier aircraft cable, struts across the panels, and commercial-grade hinges and rollers. That means different parts and more tension to handle safely, and it's work our techs do every day across DFW.
Our dock door spring broke — how fast can you get a bay back up?＋
Usually same day. A broken commercial spring leaves a couple hundred pounds of steel dead in the opening and stops that bay cold, so we prioritize it. We stock common commercial springs and cable on the trucks and run 24/7 for the ones that can't wait. Call (214) 624-6348 and we'll get a tech rolling.
Should we upgrade to high-cycle springs?＋
On a busy door, almost always yes. A standard spring is rated around 10,000 cycles — on a dock door running all day, that's months, not years. High-cycle springs (25,000 up to 100,000 cycles) cost a bit more up front but last far longer and cut down on emergency downtime, so they usually pencil out fast on a hard-worked bay. We'll tell you honestly where your door lands.
Can you set up preventive maintenance so our doors don't strand a bay?＋
We can, and on commercial doors it pays for itself. We'll put your doors on a scheduled plan — checking spring wear and cycle life, cables, rollers, hinges, struts, and balance, and catching a tired part before it snaps mid-shift. On doors that cycle this hard, staying ahead of the wear is the cheapest way to avoid an emergency that shuts a bay down.
Do you work with facility managers on POs and invoicing?＋
Yes, regularly. We accept purchase orders, provide clean itemized invoices with the price confirmed upfront in writing, and schedule around your operation so we're not shutting a bay down at your busiest hour. No surprise add-ons after the work's done.
Is it your own techs, and is the work guaranteed?＋
Both. Every commercial sectional repair is done by our own in-house, background-checked Trusty techs, never a subcontractor, and we back the parts and labor with a warranty. We've kept DFW businesses running since 2020, and if something's not right after we leave, we come back and make it right.
