Short answer
A rolling steel door in Houston usually fails in one of three places: the curtain slats jam or come out of the side guides, the spring tension in the barrel weakens so the door is too heavy, or the operator or chain hoist fails. Each needs a different repair, so diagnosis comes first.
Signs a rolling door needs service
Hard to lift by hand or chain
Barrel springs are weakening.
The door drifts down
Tension is too low to hold it open.
Slats catch in the guides
Bent guides or damaged slat ends.
Grinding at the top
Barrel bearings or the hood are worn.
The lock will not engage
The curtain is out of line.

How a rolling steel door works
A rolling steel door is a curtain of interlocking steel slats that coils around a barrel above the opening. Springs inside the barrel counterbalance the curtain, and the edges ride in steel guides on each side. The door is opened by hand, by a chain hoist or by an operator.
They suit openings where headroom is limited or security matters most, such as warehouses, storefronts, storage units and service counters, because the coiled curtain takes up very little space above the opening.
Curtain out of the guides
When slats come out of the side guides, usually after a vehicle bump or wind pressure on the curtain, the door jams and can tear the slat ends. We take the tension off, work the curtain back into the guides, and replace damaged slats or end locks so the curtain stays engaged. Bent guides are straightened or replaced, because a guide that pinches the curtain will push it out again within days of the repair. Wind locks on the slat ends help keep the curtain in place.
Spring barrel tension
The springs inside the barrel weaken over years of cycles, and the door becomes heavy to lift or drifts down when opened. Adjusting or replacing the barrel springs restores the balance so the door lifts easily by hand or operator. It is work done under heavy tension with the curtain secured, and on large doors it needs a lift, so it is never a job for anyone without the right tools and training. We also check the barrel bearings while tension is off.
Rolling security grilles
Security grilles are open-curtain rolling doors used on storefronts, mall units and pharmacy counters. They let air and light through while closing off the opening. Grilles suffer the same guide and barrel problems as solid doors, plus bent links from forced entry attempts. We repair links, guides and locks, and replace grille curtains when the damage is widespread, so the opening can be locked again the same night where parts allow. We also check that the grille's lock lines up with its keeper.
Rolling doors after a Houston storm
Houston's big storms, like Hurricane Ike, which left about 2.1 to 2.2 million CenterPoint customers without power, test rolling doors in two ways: wind pressure pushes curtains out of their guides, and power outages leave operator-driven doors stuck until someone works the manual hoist. After a storm we see both, so we check the guides, wind locks and hoist as well as the operator before calling a rolling door fixed.

What drives the cost of rolling door service
Rolling door repairs are priced by what failed and the size of the door.
- 1
Door size. Larger curtains are heavier and need more tension.
- 2
Curtain damage. Replacing slats or a full curtain changes the price.
- 3
Barrel springs. Adjusting is less than replacing.
- 4
Operator or hoist. Motor and chain hoist repairs are priced separately.
- 5
Lift access. High doors need a lift.
Questions about this job
Rolling steel door questions
The springs in the barrel have lost tension, or the curtain is binding in the guides.
Yes, by relieving tension, re-seating the curtain and replacing damaged slats or guides.
Yes, including links, guides, locks and full grille curtains.
No. Barrel springs carry heavy tension and need the right tools.
Yes, along with chain hoists for manual operation.
Yes, many makers offer rated rolling doors with wind locks for exposed openings.
