Commercial Garage Door Maintenance Plans
The cheapest commercial door repair is the one that never happens in the middle of a shift. G Brothers sets up scheduled maintenance for commercial doors across the Denver metro, from a single shop door to every door on a multi-property account.
What this service covers
Real work by background-checked local technicians, quoted at a flat rate you approve before anything begins.
Counterbalance
Springs, cables and drums inspected and adjusted, with worn springs flagged before they break.
Moving parts
Rollers, hinges, bearings and track lubricated, tightened and aligned.
Rolling doors
The curtain, guides, barrel and bottom bar checked on roll up doors.
Operators and safety devices
Limits, force, photo-eyes and safety edges tested, so the door stops and reverses when it should.
Repairs quoted first
Anything that needs repair is quoted flat before we do it.
Why plan maintenance on commercial doors
Doors that cycle all day wear springs and rollers far faster than a home door.
A door that fails mid-shift costs more than the visit that would have caught it.
Worn parts found early are often a small repair. Found late, they take the door out of service.
Tested safety devices protect the staff and vehicles that pass under the door.
One door or many properties
We set the visit schedule by how hard each door works. A busy dock door needs more visits than a shop door that opens twice a day. Property managers with several buildings can put every door on one account, with a certificate of insurance usually sent within 24 hours.
Commercial maintenance questions
How often should a commercial garage door be serviced? It depends on how many times a day it runs. A light-use shop door may need a visit or two a year, while busy dock and high-cycle doors need more. We set the schedule from how your doors are used.
What should a commercial garage door be lubricated with? A lubricant made for garage door hinges, rollers, bearings and springs, not a degreaser. Tracks and guides should be kept clean rather than greased. On a maintenance visit we do this for you.
Do you handle both residential and commercial garage doors? Yes. We service residential garage doors too, so one call covers your home and your business.
Is a maintenance plan worth it for one door? For a door the business depends on every day, usually yes. One unplanned shutdown can cost more than a year of planned visits.
