If you've ever had a roll-up door jam during peak warehouse hours, you know exactly how much downtime costs. Commercial garage doors in Exeter aren't like the residential models most people think about. They're engineered for heavy-duty use, frequent cycling, and the kind of punishment that comes with daily business operations. I've spent 15 years pulling trucks to job sites across New Hampshire, and I can tell you: commercial doors fail differently, and they need different solutions.
Residential doors typically cycle 5 to 10 times per day. A warehouse roll-up door? Try 30, 50, sometimes 100 cycles daily. That's why commercial systems use heavier springs, industrial-grade openers, and reinforced track systems. The springs alone last 5 to 7 years under commercial use, compared to 10 to 15 years on a home garage door. See our guide on garage door cost & pricing in exeter: what homeowners actually pay.
The cables are thicker. The panels are steel, not aluminum or insulated composite. The opener motors are commercial-rated, pulling exponentially more load. Even the safety features differ. A commercial door needs photo eye systems, emergency reversal, and redundant safety measures that go beyond what residential code requires.
Weight matters too. A standard residential door weighs around 300 to 400 pounds. Commercial warehouse doors can weigh 800 to 1,500 pounds or more. That's why you can't just call any garage door company. You need technicians who understand structural loading, commercial electrical codes, and the specific demands of business continuity.
When we install commercial garage doors in Exeter, the process is nothing like a residential job. We start with a structural assessment. We check the header beam, the side jambs, and the floor condition. A commercial door puts enormous stress on your building frame, and installation shortcuts lead to expensive failures.
The opener selection is critical. Commercial doors use either chain drive or belt drive systems, but commercial-grade versions. These aren't the same as residential models. They're built to handle thousands of cycles without burnout. We also install backup power systems for many clients. If the power goes out during business hours, your door still operates.
Spring selection determines everything else. Commercial doors typically use either extension springs or torsion springs, and the gauge and wire diameter are much heavier than residential specifications. Torsion springs for commercial use usually run 0.273 to 0.312 inch wire diameter. That's a significant step up.

We also handle the control systems. Most commercial operations need push-button openers, remote controls, and sometimes keypad access. Some clients need wireless systems that integrate with their security setup. That's where experience matters. A technician who's only worked on residential doors won't know how to wire a commercial opener safely or troubleshoot a multi-button control panel.
Here's the truth: maintenance costs far less than emergency repairs. A commercial door that breaks during business hours can shut down your entire operation. I've seen warehouse managers lose thousands of dollars per hour when a roll-up door gets stuck.
Regular lubrication is non-negotiable. Commercial doors need monthly inspections and lubrication schedules. We use commercial-grade lubricants, not the spray cans homeowners buy at the hardware store. Tracks need cleaning. Springs need load testing. Cables need visual inspection for fraying or damage.
We also recommend quarterly professional inspections. During these visits, we check spring tension, test all safety features, and verify that the door cycles smoothly under full load. Many of our commercial clients in Exeter and surrounding areas have maintenance contracts with us. It costs less than one emergency repair call.

Commercial garage doors cost more than residential models. A basic heavy-duty roll-up door runs $2,500 to $5,000 installed. Premium systems with backup power, advanced controls, and high-cycle springs can exceed $8,000. Installation labor for commercial work is also higher because the job takes longer and requires multiple technicians.
But here's what matters: this is an investment in your business. A warehouse without a reliable door isn't a warehouse. When you're evaluating cost, factor in downtime risk. Many businesses find that the peace of mind is worth the premium.

How often should commercial garage doors be serviced? Commercial doors need monthly lubrication and inspections, plus quarterly professional maintenance checks. High-cycle facilities may need more frequent service. Regular maintenance catches small issues before they become expensive downtime events.
What's the typical lifespan of a commercial garage door? Heavy-duty commercial doors last 10 to 15 years with proper maintenance. High-cycle facilities may see doors wear out faster. Spring replacement every 5 to 7 years is normal. Proper care directly extends lifespan.
Can I use a residential garage door opener on a commercial door? No. Residential openers lack the duty cycle rating, safety features, and power needed for commercial use. Commercial doors require industrial-grade openers designed for frequent cycling and heavier loads.
What safety features do commercial doors need? Commercial doors require photo eye systems, emergency manual override, mechanical locks, and emergency reversal systems. Building codes mandate these for business safety and liability protection.
How quickly can you install a commercial garage door in Exeter? Most installations take one to two days, depending on system complexity. We offer same-day estimates and can often expedite parts for urgent replacements. Call (978) 574-7767 to discuss your timeline.
