Common seller tricks in garage-door
A listing may lean on a manufacturer relationship and a ‘24-hour emergency’ reputation without showing whether either one survives a change of owner.
- Dealer or installer agreements that require the manufacturer’s consent, or that are personal to the seller.
- Warranty and spring-callback costs that are not reserved.
- A parts inventory with obsolete openers and operators counted at full value.
- The lead tech as the only person who can diagnose the main product lines.
- Builder or property-management volume that is all handshake.
Which numbers to verify
Split service, springs, operators, and new-door installs (especially builder work). Look at average ticket and callback rates. Reconcile deposits. Recast owner dispatch and after-hours calls. If a big share is new construction, treat that as cyclical, not recurring residential service.
Licensing and key-person risk
Some states treat garage-door installation as contracting; others are lighter. The more important paper can be the manufacturer dealer agreement and product-training certificates. Those often do not transfer automatically. Insurance for service work and for trucks with lift gates should be reviewed at current premiums.
Equipment and condition
Trucks with racks and lift gates, torsion tools, and testers are the kit. Look at mileage and lift-gate condition. A messy, obsolete parts room is not an asset until it is counted and aged. Shop space and a safe spring-winding setup matter for liability.
Seasonality and the calendar
Service calls continue year-round, with some weather bumps. New-construction installs follow the builders. If the company is half builder work, monthly numbers will follow housing starts, not broken springs. After-hours coverage is part of the offer; ask who actually takes it.
Customer concentration
A production builder or a property manager can be a large, low-margin slice. Retail service is more fragmented. If one brand of opener is most of the parts profit, a lost dealer agreement is a lost business line.
Questions to ask before you make an offer
- Which manufacturer dealer agreements are in place, and what is required to keep them after a sale?
- Please split revenue between service, springs, operators, and new installs for three years.
- What is the callback and warranty rate on springs and openers, and is there a reserve?
- Which technicians are trained on the core product lines, and will they stay?
- May I age the parts inventory and exclude obsolete items?
- What share of work comes from builders or property managers, and is any of it contracted?
- How is after-hours service staffed, and how many of those calls does the owner take?
- May I inspect trucks, lift gates, and liens?
- Are there open injury or property-damage claims involving springs or doors?
- After an LOI, may I speak with your accountant and a lead technician?
