The Property Manager's Garage Door Vendor Checklist: 7 Things to Verify Before You Add Them

Adding a vendor to your approved list is a small decision you live with for years. The garage door trade makes it harder than most: one-truck operations with no insurance, lead-generation websites that resell your call, and outfits that quote one number on the phone and another on the invoice. When the vendor touches a door or gate your tenants drive under every day, a bad pick isn't just an overbilling problem — it's a liability problem with your building's name on it.

This is the checklist we'd tell any property manager to run before adding a door vendor — including on us. It's seven items, none of them exotic, and a legitimate contractor can clear all seven in a day. Where we describe how Smartest Garage Doors measures against each item, those are statements of fact about how we operate, and you should verify them the same way you'd verify anyone else.

1. A COI Naming Your Building as Certificate Holder

The single fastest filter. Before any work order, the vendor's insurance broker should issue a certificate of insurance naming your building or management company as the certificate holder — and for many buildings, as additional insured per your management agreement's requirements.

What to check on the certificate:

• General liability limits that meet your building's vendor requirements
• Workers' compensation coverage — a technician injured on your property without it becomes your problem
• Current policy dates, and a calendar reminder to collect the renewal certificate
• The certificate comes from the broker, not as a PDF the contractor edited himself

A vendor who hesitates, stalls, or offers a generic certificate that names nobody is telling you something important before the first job. We issue COIs naming the building on request as a standard part of onboarding — it's a same-day email to our broker, and any vendor for whom it's harder than that is a vendor to skip.

2. License and Insurance You Verified Yourself

Don't take the website's word for it. Contractor licensing is public record, and verification takes minutes:

• NYC: check the DCWP (Department of Consumer and Worker Protection) license lookup for home improvement contractor licenses
• New Jersey: the Division of Consumer Affairs maintains a public registry of registered home improvement contractors
• Connecticut: the Department of Consumer Protection's eLicense portal
• Match the legal entity name on the license to the name on the COI and the name on the invoice — mismatches between the brand on the truck and the entity on the paperwork are how claims get denied

While you're at it, search the legal entity name plus "complaints" and check how long the entity has existed. A two-month-old LLC with a ten-year-old website usually means the operator has burned a name before.

3. Written, Per-Property Invoicing

If you manage more than one building, billing hygiene is the difference between a vendor who saves you time and one who costs you a reconciliation headache every month. Require, in writing:

• One invoice per property, with the property address on it, never a combined invoice across buildings
• Itemized line items — parts, labor, and trip charges broken out, not a single lump sum
• The work order or PO reference your system issued, on the invoice
• Quotes in writing before work begins, with the rule that nothing above the quoted scope happens without a documented approval

This isn't bureaucracy for its own sake. Per-property invoicing is what lets you charge costs back to the right building, answer a board's question six months later, and spot the vendor whose "emergency" rate quietly migrated into daytime calls. We invoice per property with itemized line items as standard practice, because portfolio accounts are most of our commercial work and unallocatable invoices get rejected anyway.

4. Photo Documentation on Every Job

You can't be at every service call, and neither can your super. Photo documentation is how you supervise work you didn't witness:

• Before photos showing the condition and the failure
• After photos showing the completed repair
• Photos of the failed parts that were replaced — the actual broken spring, the frayed cable
• Delivered with the invoice, not available on request

This protects both sides. For you, it's proof to the board that the repair the building paid for actually happened, and evidence in any later dispute or insurance claim. For the honest vendor, it's proof the part really was broken. A vendor who resists photographing their own work is asking you to take a lot on faith. We attach before/after photos to every commercial job as standard — it's also how our photo estimate process works in reverse: you can send us photos of a failed door and get a preliminary quote before anyone rolls a truck.

5. A Written Response Commitment for Tenant-Affecting Outages

A stuck parking gate is not a routine work order. Tenants are trapped in or locked out, cars are exposed on the street, and your phone is ringing. Before that night arrives, get the vendor's response terms in writing:

• How emergency calls are dispatched — a person who answers, or a voicemail that's returned tomorrow?
• Priority terms for your account — do your buildings go to the front of the queue?
• 24/7 availability, actually staffed, not just printed on the truck
• An honest ETA practice: be suspicious of anyone promising a fixed arrival time in a contract for every emergency, everywhere, always. Traffic and job stacking are real. What you want is priority dispatch and a firm ETA when you call.

That last point is worth dwelling on: the vendors who promise "30 minutes, guaranteed" in their marketing are the same ones who go quiet at 11pm. We run 24/7 emergency dispatch with priority for account clients, and we give you an exact ETA when you call — which is the commitment we can actually keep every time.

6. One Contact Across the Portfolio

If you run five buildings, you should not have five different experiences with the same vendor. Ask how the account is structured:

• A single named contact who knows your portfolio, your COI requirements, your billing format, and your buildings' door histories
• Consistent pricing across properties, agreed once, not renegotiated per call
• Per-door records kept by the vendor — gate model, operator, spring specs, service history — so the third repair on the same gate doesn't start with rediscovery

The alternative is a call-center relationship where every ticket is a cold start and every technician is seeing the building for the first time. Account structure is also covered in detail on our property managers page, including how we onboard a portfolio.

7. References from Buildings Like Yours

Finish with references — but make them specific. "Do you have references?" gets you the vendor's two happiest customers. Instead ask:

• References from the same building type — a condo board, a co-op, a rental portfolio manager — not a homeowner
• For a maintenance account reference, not a one-off repair: you're evaluating the relationship, not one job
• The questions that matter: Do invoices arrive clean and allocatable? What happened the last time something went wrong? Did pricing hold over time?

Then cross-check against public reviews, reading the negative ones for how the company responded. Ours are at reviews, and our commercial scope — gates, rolling doors, dock doors, operators — is laid out at commercial garage door repair. Run the whole checklist on us; that's what it's for.
