Hiring a Tradesperson: What to Ask, Verify, and Expect Before Work Begins

Why Preparation Matters Before You Hire Anyone

Hiring a tradesperson for a home repair or renovation is one of the most consequential decisions a homeowner makes. Done well, the process delivers a quality result on time and on budget. Done poorly, it can mean substandard work, cost overruns, or disputes that drag on for months. The good news is that a structured approach — asking the right questions, verifying credentials, and putting agreements in writing — dramatically reduces your risk.

This guide walks you through what to do before a single tool is unboxed, covering the verification steps, the right questions to ask, and what a solid working agreement looks like. For context on related project planning, see our guide on when permits and inspections are required — because some work legally cannot begin without official sign-off.

Verifying Credentials: Licences, Insurance, and References

Before you discuss the scope of work, confirm the basics. Licensing requirements vary by state and trade — electricians, plumbers, and HVAC technicians typically require state-issued licences, while general contractors may be licensed at the county or city level. Ask to see the licence number and verify it through your state's licensing board website. An unlicensed tradesperson performing regulated work may leave you liable for code violations and void your homeowner's insurance.

Insurance is equally non-negotiable. Request proof of both general liability insurance (covers damage to your property) and workers' compensation (covers injuries to workers on your property). Ask the insurer to confirm the policy is current — a photocopy of an expired certificate is not protection.

References from recent clients round out the picture. Ask specifically for projects similar in scope to yours, completed within the past 12 to 24 months. Follow up with those references directly and ask about timeline adherence, communication, and how disputes or changes were handled.

Getting and Comparing Quotes the Right Way

Obtain at least two to three written quotes for any significant project. Verbal estimates are not enforceable and often omit critical details. A useful quote should specify: the scope of work in plain language, materials to be used (type and grade), labour costs broken out from material costs, a project timeline with start and estimated completion dates, and what is explicitly excluded.

When comparing quotes, resist the reflex to choose the lowest number. A quote that is significantly below the others may indicate cut-rate materials, missing scope, or a contractor planning to recoup costs through change orders later. Ask each contractor to explain any line items that differ substantially from the others. This conversation alone reveals a great deal about their transparency and knowledge.

If your project involves structural changes or wall removal, our overview of open-plan renovation trade-offs can help you ask more informed questions about what the quote should cover.

What a Sound Contract Must Include

A handshake agreement is not a contract. Before any work begins, insist on a written contract signed by both parties. At minimum, it should include:

• Detailed scope of work — what will be done, where, and how
• Materials list — brand, model, or grade specifications where relevant
• Start date and estimated completion date
• Payment schedule tied to defined milestones, not calendar dates
• Change order process — how additions or changes to scope are approved and priced
• Lien waiver provisions — confirmation that subcontractors and suppliers have been paid
• Dispute resolution clause — mediation or arbitration process if disagreements arise

The payment schedule deserves particular attention. A reasonable structure might be a modest deposit (often 10–20% of the total) to secure materials, milestone payments as defined phases are completed, and a final payment — typically 10–15% — held until you have done a final walkthrough and are satisfied with the work.

Setting Expectations for the Work Period

Clear expectations before day one prevent the majority of on-site conflicts. Agree in advance on working hours, site access procedures, how the workspace will be protected and cleaned daily, and who the primary point of contact is for questions and decisions. Establish how communication will happen — a written log (email or a project app) is far preferable to phone calls that leave no record.

Expect some disruption — renovation and repair work is inherently messy and occasionally noisy. What you should not accept is being kept in the dark about progress, cost changes being applied without your written approval, or subcontractors arriving without introduction. Your contract's change order clause exists precisely to handle the unexpected. Use it.

Finally, keep your own project file: copies of the signed contract, all change orders, payment receipts, permit documents, and inspection sign-offs. This documentation is invaluable if a dispute arises, and it supports your home's resale history.
