We understand how important your door is to your daily routine. It’s not just a piece of hardware—it’s the gateway to your warehouse, the barrier to your retail space, or the access point to your underground parking. When something goes wrong, it’s not just inconvenient—it’s a disruption to your workflow, your security, and your bottom line.

That’s where our team steps in. We specialize in same-day commercial overhead door repairs, handling everything from basic cable fixes to complicated motor troubleshooting. Our trucks are stocked with the parts most businesses need, and our technicians are trained to diagnose problems quickly and get the job done right the first time.

Overhead Door Problems? We’ve Seen It All

In commercial settings, overhead doors work hard every day. They open and close dozens of times, sometimes hundreds in high-traffic environments. Over time, that kind of use wears parts down. Springs can snap without warning. Rollers and tracks get out of alignment. Motors and Jackshaft operators might slow down or stop responding. We’ve seen it all—and we know how to fix it.

Many business owners first notice trouble when their door starts moving slower than usual or makes noises it never used to. Others experience sudden failure—a door stuck halfway open, cables off the drum, or panels crunched from a delivery truck accident. Some call us after their remote or wall switch stops working, unsure if the problem is electrical or mechanical.

The good news is, most commercial overhead door issues can be fixed quickly when you call experienced techs like ours. We don’t waste your time. We show up ready to work, figure out the issue on-site, and either repair or replace the parts that are causing trouble.

Trusted Repairs Using the Best Commercial Brands

At Quest Doors, we only work with top commercial-grade brands because your business deserves reliability, not shortcuts. We handle repairs and replacements for LiftMaster commercial openers, which are some of the most commonly used systems in warehouses, shops, and parking garages across Canada. We also service and install Manaras operators, which are known for their high performance in industrial spaces. If you’re using a Jackshaft opener, our team knows exactly how to diagnose and repair these side-mounted systems without interrupting your ceiling space or building layout.

Sometimes, fixing the issue is as simple as adjusting limit settings, balancing the door, or replacing worn rollers. Other times, we’re dealing with torsion springs that have snapped under load or cable drums that have frayed over time. Either way, our team is prepared. We bring commercial-rated parts, not residential substitutes, so your repair lasts longer and performs the way it should.

Commercial Door Springs & Cable Repairs

One of the most common repairs we handle is broken springs. Commercial torsion springs work under extreme tension to lift and lower heavy doors day after day. When one breaks, your door won’t move properly—sometimes it won’t move at all. Trying to force it open can make things worse or even lead to injuries. Our team replaces these springs safely, using the correct size and cycle rating for your specific door. We also handle cable replacements, since frayed or snapped cables are often the result of old, unbalanced springs or high-cycle wear.

Motor Problems & Jackshaft Operator Solutions

Commercial door motors are built to last, but they still need attention over time. If your LiftMaster or Manaras operator is running loud, stalling, or failing to open consistently, it might not need a full replacement. Sometimes, we can reprogram limit switches, adjust the clutch, or replace sensors. If the motor is beyond repair, we’ll recommend the right replacement—not just any opener, but one that suits your door’s size, cycle count, and daily use.

For businesses using Jackshaft operators, we provide maintenance, repairs, and full replacements when needed. These side-mounted systems are perfect for saving ceiling space, but they require specific know-how. We’ve worked on thousands of them across the GTA, so you can count on a solution that works.

Section Repairs & Door Panel Fixes

It’s not always the mechanism that fails. Sometimes a truck backs into a panel or your door gets dented during loading. In cases like these, we offer sectional repairs and panel replacements to restore your door without the cost of a full system change. Our team matches panel styles and colors whenever possible, so your building looks professional and functions properly again.
