Building Your Vendor Network: How to Find Reliable Contractors

It's 10 PM on a Saturday and your tenant calls: water is pouring from under the bathroom sink. If you don't already have a plumber who answers at night, at an emergency rate you've agreed on, you'll be searching online while the water runs.

The Vendors Every Landlord Needs

Core Trades (Must-Have)

Plumber

• Emergencies: burst pipes, water heater failures, sewer backups
• Routine: leaky faucets, running toilets, fixture replacements

Electrician (Licensed)

• Safety issues: outlet sparks, breaker problems
• Upgrades: new fixtures, panel work
• Many jurisdictions require licensed electricians for permit work

HVAC Technician

• Heating and cooling repairs
• Seasonal maintenance
• Look for EPA 608 certification (required for refrigerant handling)

General Handyman

• Minor repairs: door knobs, drywall patches, faucet fixes
• Tasks under your state's licensing threshold
• Your most frequently called vendor

Roofer

• Leak repairs
• Storm damage assessment
• Gutter maintenance

Other Services

Locksmith

• Lockouts
• Re-keying between tenants
• Lock replacements and upgrades

Pest Control

• Infestations (immediate response)
• Preventive treatments (scheduled)

Appliance Repair

• Refrigerator, washer, dryer, dishwasher
• Often cheaper than replacement for newer units

Cleaning Service

• Move-out deep cleaning
• Turnover preparation

Landscaping

• Regular lawn maintenance
• Seasonal cleanup

The Backup Rule

For each critical trade (plumber, electrician, HVAC), have:

• Primary vendor: Your go-to
• Backup vendor: For when primary is unavailable
• Emergency contact: Someone who answers nights and weekends

Associated Builders and Contractors estimates the construction industry needs about 349,000 more workers in 2026. A 2026 Bring Back the Trades report projects about 1.4 million openings by 2030 across seven trades, including plumbers, electricians and HVAC technicians. Good contractors are in demand, so line up backups.

How to Find Good Contractors

Best Sources

Personal Referrals (Most Reliable)

• Ask other landlords in your area
• Real estate investor meetups
• Your current vendors (they often know quality peers)

Your plumber probably knows a good electrician, and your lawn service probably knows a snow removal company. Ask them.

Professional Networks

• Local landlord associations (often have preferred provider lists)
• National Association of the Remodeling Industry
• Building inspectors (they see contractor work quality firsthand)

Online Resources

• Thumbtack, Angi, HomeAdvisor (get multiple quotes)
• Google Reviews and Yelp (look for patterns across many reviews)
• Better Business Bureau (check for complaints)

The Vetting Process

Step 1: Verify Credentials

Check your state's licensing board:

• Is the license current and valid?
• Any disciplinary actions?
• Does the license cover the work you need?

Step 2: Confirm Insurance

Request a Certificate of Insurance (COI):

• General liability insurance (protects your property)
• Workers' compensation (protects you from injury claims)

Call the insurance company to confirm the policy is active. For major projects, ask to be added as an "additional insured" on their policy.

Step 3: Check References

Request at least 3 references and call them:

• How was the work quality?
• Were they on time and responsive?
• Did the final cost match the estimate?
• Would you hire them again?

Step 4: Get Multiple Bids

For any job over $500, get 3 written estimates:

• Ensures you're comparing the same scope
• Reveals pricing outliers
• Be cautious of bids that are significantly higher OR lower than average

Handyman vs. Licensed Contractor

When do you need a licensed contractor vs. a handyman?

Use a Handyman (often $50-$125/hour) for:

• Minor repairs under your state's licensing threshold (since 2025, California allows unlicensed work on jobs under $1,000, labor and materials included, with no permit required; other states differ)
• Work that doesn't require permits
• Tasks like: replacing fixtures, patching drywall, painting, minor plumbing fixes

Use a Licensed Contractor for:

• Any work requiring permits
• Major plumbing, electrical, or structural work
• Work above state-specific dollar thresholds
• Projects affecting building systems or tenant safety

The Risks of Getting It Wrong

• Fines for unlicensed work (California can fine unlicensed contractors up to $15,000)
• Liability for injuries to unlicensed workers
• Failed inspections
• Water damage from a bad plumbing job adds up fast: the average homeowners water damage or freezing claim was about $12,500 from 2017 to 2021 (Insurance Information Institute)

When in doubt: If it needs a permit, get a licensed contractor.

Negotiating Rates

Offer Volume

"I have 10 properties and will send you all my plumbing work."

Steady work is worth something to a contractor, so mention it when you ask for a rate.

Offer Favorable Terms

• Prompt payment: Pay invoices within 7-14 days
• Flexible scheduling: Let vendors fit you in during slow periods
• Reliable referrals: Refer quality vendors to other landlords

Negotiate Specifics

• Materials: Accompany them to suppliers and purchase materials yourself
• After-hours rates: Agree on emergency pricing before you need it
• Annual contracts: Guaranteed work in exchange for better rates

What Not to Do

• Don't nickel-and-dime good vendors on every invoice
• Don't expect emergency pricing for routine work
• Don't demand immediate availability if you don't pay for it

Good vendors have other clients and will put them first if you're hard to work with.

Managing Vendor Relationships

How to Communicate

• Clear instructions: Detailed scope, access info, tenant contact
• Written records: Use email for formal communications
• Responsive communication: Don't leave vendors waiting for answers

Payment Practices

• Pay promptly: Net-15 or Net-30, and stick to it
• Don't dispute fair charges: If the work was done, pay for it
• Clear invoicing: Make sure expectations match before work begins

Performance Tracking

• Document every job: What was done, when, cost, quality
• Review quarterly: Are they still meeting your standards?
• Give feedback: Let them correct mistakes without penalty

Building the Relationship

• Share knowledge: Give them property maps, system info, access codes
• Give credit: Refer them to other landlords
• Show appreciation: Thank them for good work

Emergency vs. Non-Emergency Maintenance

Not every maintenance request needs a same-day response.

Emergencies (Immediate Response)

Issues posing immediate danger or threat to property:

• Burst pipes or major water leaks
• Sewer backups
• No heat in cold weather
• No A/C in extreme heat
• Complete electrical outage
• Gas leaks
• Fire or flood damage

Response: Within hours to 24-48 hours maximum

Non-Emergencies (Routine Response)

Issues that are inconvenient but not dangerous:

• Leaky faucet
• Broken cabinet
• Malfunctioning dishwasher
• Light bulb replacement
• Cosmetic repairs

Response: Acknowledge within 24 hours, complete within 7-30 days

State law can set shorter deadlines. Washington, for example, gives landlords 24 hours after written notice to restore heat, water or electricity, 72 hours for a broken refrigerator, stove or major plumbing fixture, and 10 days for most other repairs (RCW 59.18.070). Check your state's rules.

Building Your Emergency System

1. Create a tiered vendor list with primary and backup contacts
2. Negotiate after-hours rates in advance
3. Include emergency expectations in vendor contracts
4. Keep contact information accessible 24/7
5. Communicate response expectations to tenants at lease signing

Red Flags When Hiring

Payment Red Flags

• Demands large deposit (over 20%) upfront
• Cash-only payments
• Checks made out to individuals vs. companies
• Significantly lower bids than competitors

Pressure Tactics

• "This offer is only good today"
• Pushing for immediate decisions
• Door-to-door solicitation
• Discouraging you from getting other bids

Documentation Issues

• Only verbal estimates (no written proposal)
• Asks you to pull permits (sign they're unlicensed)
• No proof of insurance
• Reluctance to provide references

Professional Concerns

• No physical business address
• Unresponsive during the estimate phase
• Negative reviews on BBB, Google, or Yelp
• Can't verify insurance coverage when you call
