How to find and vet a good contractor for your rental property

A bad contractor can turn a $400 repair into a $4,000 problem. A good one shows up when they say they will, does the work properly, and doesn't disappear after payment. The difference between landlords who manage maintenance smoothly and those who dread every call from a tenant usually comes down to whether they've built a reliable roster of trades.

This takes time — but there's a process that shortens it.

Why you need a roster before you need it

The worst time to find a contractor is at 9pm when a tenant has no heat. Urgency kills your ability to vet anyone, so you end up calling whoever answers first, paying premium emergency rates, and hoping for the best.

The goal is to have at least one vetted contact for each trade category before you need them:

• Plumber
• Electrician
• HVAC technician
• General handyman (for small repairs that don't require a licensed trade)
• Roofer (especially if you own older properties)
• Locksmith

You won't build this overnight. But every maintenance issue is an opportunity to add someone to the list — or cross someone off it.

Where to find contractors

Referrals from other landlords — This is the most reliable source. Someone who has already used a contractor and would hire them again is more useful than any online review. Ask in local real estate investor groups, landlord associations, or property management forums.

Referrals from other trades — Contractors talk to each other. If you have a plumber you trust, ask who they'd recommend for electrical work. Tradespeople tend to refer within networks they know and trust.

Online platforms — HomeAdvisor, Thumbtack, Angi (formerly Angie's List), and similar platforms aggregate contractors and include reviews. Use these to find candidates, not to make final decisions. Reviews can be gamed; they're a starting point.

Local supplier yards — Plumbing supply houses, electrical supply stores, and lumber yards see contractors every day. The staff often know who does good work and who doesn't. It's an underused source.

Google search + reviews — Searching for "[trade] near me" plus reading Google Reviews gives you a shortlist. Look at how they respond to negative reviews — a defensive or dismissive response to a complaint tells you more than the complaint itself.

How to vet a contractor before hiring them

Finding a name is step one. Vetting is step two, and most landlords skip it.

Verify their license. Most jurisdictions require electricians, plumbers, and HVAC technicians to be licensed. Ask for their license number and check it against your state or provincial licensing board's online database. This takes two minutes and eliminates a lot of risk.

Ask for proof of insurance. A contractor working on your property should carry both general liability insurance and workers' compensation. If something goes wrong — a pipe bursts, a worker gets hurt — you need their insurance to be the first line of coverage, not yours. Ask for a certificate of insurance and check the expiry date.

Check references — actually call them. Ask for two or three references from jobs similar to yours in the past 12 months. Then call them. Most contractors expect you to ask for references and not follow through. The ones who give you references knowing you'll call them are telling you something.

Questions to ask a reference:

• Did they show up when scheduled?
• Did the final price match the estimate?
• Did they leave the job site clean?
• Did any issues come up after the work was done, and how did they handle it?
• Would you hire them again?

Get a written quote before any work starts. A verbal agreement about price is an invitation for a dispute. A written quote should include the scope of work, materials to be used, estimated timeline, and total cost. Any change to scope should be documented in writing before work continues.

Red flags to watch for

No license or "I don't need one for this job." For licensed trades, they always need one. If they're claiming otherwise, move on.

No written quote — just a verbal number. This almost always ends with "it was more work than expected."

Asking for more than 30–40% upfront. A deposit to cover materials is reasonable. Full payment or large upfront sums before work is complete are not.

Reluctance to pull permits. For work that requires a permit, some contractors will offer to skip it to save time or money. Don't accept this. Unpermitted work can void your insurance, create problems when you sell, and leave you liable if something goes wrong.

Vague about timeline. "I'll come by sometime next week" with no specific day or window signals disorganization. Good contractors know their schedule.

No fixed business address or an untraceable phone number. If you can't find any record of them beyond a phone number, you have no recourse if something goes wrong.

Getting and comparing quotes

For any job over a few hundred dollars, get at least two quotes — ideally three. This isn't just about price; it's about understanding what the job actually requires. If one quote is dramatically lower than the others, either they've misunderstood the scope or they're planning to cut corners.

When comparing quotes, make sure they're comparing the same thing:

• Same scope of work
• Same materials (branded vs. generic can make a meaningful difference)
• Same warranty on labor

The cheapest quote is rarely the right choice. The most expensive isn't either. You're looking for someone whose price reflects the actual work, who communicated clearly in the quoting process, and whose references checked out.

Building a long-term relationship

A contractor who knows your properties is worth more than a cheaper one who doesn't. Once you find someone reliable, treat them accordingly:

Pay promptly. Cash flow is a constant pressure for small contractors. Paying on time — or early — makes you a preferred client. Preferred clients get prioritized when schedules are tight.

Be organized. Have the tenant's contact information ready, be clear about access, and make sure the issue is described accurately before they show up. Contractors who show up to find a different problem than they quoted for charge for the change.

Give them enough notice. Except for true emergencies, a day or two of notice lets them schedule properly. Last-minute requests eat into their day and yours.

Refer them. If a contractor does good work, tell other landlords. Contractors remember who sent them work, and goodwill tends to come back.

The goal over time is a small roster you trust — usually three to five people across the main trade categories — that you can call without having to re-vet anyone. That roster is what makes maintenance manageable instead of chaotic.

Onsite lets you store your contractor roster alongside your properties — name, trade, phone number, and dispatch history — so you're never searching your contacts for the plumber's number at the wrong moment.
