Garage door installers insurance checklist: what a garage door installer should carry

The garage door installer insurance checklist

QUICK ANSWER

Garage door installers usually carry general liability, workers' compensation and commercial auto. Garage door installers work with torsion springs that store enough energy to injure, install openers whose safety sensors are a legal requirement, and respond to service calls where a customer's car is already under the door. The property manager and the permit office ask for proof of each. The checklist below covers who asks and how to check what you have.

Who asks a garage door installer for what

Who	What they usually want to see
Property managers & HOAs	General liability with the manager and owner as additional insureds, and workers' compensation
Cities, counties & permits	General liability, auto and workers' compensation at the limits in the permit or contract
Banks, lenders & SBA loans	Property or auto physical damage with the lender as loss payee, and liability proof at closing and every renewal

Each of them wants a certificate, and most want it again at every renewal. A live certificate link from the wallet shows today's coverage to every holder and tells them when it changes.

How to check what you already have

General liability declarations page. Three liability numbers matter: each occurrence, general aggregate and the products–completed operations aggregate. Then the forms list: blanket additional insured, waiver of subrogation and primary and non-contributory wording satisfy every contract; scheduled forms satisfy one.
Workers' compensation information page. Item 3.A must list every state you work in, item 4 must carry the right class codes, and the employers' liability limits should meet what contracts ask. Check that the estimated payroll is close to this year's.
Auto schedule. Every vehicle listed with the right garaging address and use; symbols that include hired and non-owned auto; physical damage with the lender as loss payee where the vehicle is financed.
Equipment schedule. Owned items scheduled above the per-item threshold, a blanket limit for small tools, leased or rented equipment included, and the valuation (replacement cost or actual cash value).
Umbrella schedule of underlying insurance. Each primary policy listed with the limits the umbrella expects; a gap between the two is uninsured.
Hired and non-owned auto. Look for the symbols 8 and 9 or an endorsement by that name on the auto or general liability policy; without it, staff in their own cars are uninsured on company business.
Products–completed operations. The aggregate, any vendors endorsement naming buyers as additional insureds, and exclusions for specific products or markets.

What usually goes wrong for garage door installers

Safety-reverse sensors disabled or mis-set, and an injury that lands on the installer.
A customer's car damaged by a door the technician was servicing, excluded as property in your care.
Damage to the exact thing you are working on is excluded on most general liability forms; installation floaters and care, custody and control endorsements fill that hole.
A completed-operations aggregate quietly limited by endorsement; the declarations page looks fine until the forms are read.
Theft from a locked truck overnight with no tools floater, or a per-item limit lower than the one tool that mattered.
A personal auto policy on a truck with the company name on the door.

What underwriters will ask a garage door installer

Residential versus commercial door share, how safety features are tested and recorded, and the number of service technicians
Residential versus commercial split of the work
Whether any work is done above three stories or below grade
Years of completed-operations coverage with no gap
Whether you warranty your work and for how long
Total value of hand and power tools kept on the trucks

Have the answers in the wallet before the renewal and the quote request fills itself in; CoverMatch sends one application to every eligible carrier and lines the quotes up against what you have.

Renewal timing

Audits at year end compare payroll, receipts and subcontractor costs with the estimate, so keep the wallet's size figures and the subcontractor certificates current. Start comparing sixty days before expiration, and ask for the limits the next contract will need rather than the ones the last one did.

Questions people actually ask

Is an injury from a garage door we installed covered?

As a completed-operations claim, yes, when the policy includes completed operations and the safety features were installed and tested as required. The test record on the invoice is the defence; keep every one in the wallet.

A door fell on a customer's car during service. Who pays?

The car was in your care at the time, so the general liability policy may exclude it. A care, custody and control endorsement or a small bailee limit covers it; without one, the business pays for the car.

Does general liability cover damage to a customer's property while I work on it?

It covers damage to the rest of their property, not usually the part in your hands. Many forms exclude property in your care, custody or control, so a garage door installer that handles valuable items or systems needs an endorsement or an installation floater. The policy explainer in the wallet flags the exclusion when it reads your policy.

A job I finished two years ago just caused damage. Which policy pays?

The general liability policy in force when the damage happens, as long as it still includes completed operations and you kept the coverage continuous. A gap or a switch to a form that excludes completed operations is how a garage door installer ends up uninsured for old work.

Are tools stolen from my truck covered?

Under a tools floater, yes, subject to the deductible and any per-item limit. Under the commercial auto policy, no: auto covers the vehicle, not what was in it.
