TL;DR:
- Choosing the right contractor saves time, money, and prevents stress during projects.
- Ask key questions about licensing, experience, site management, permits, and communication to ensure reliability.
Choosing the wrong contractor doesn't just cost money. It costs weeks, sometimes months, of delays, rework, and stress. Whether you're planning a kitchen renovation in North Vancouver, a tenant improvement in Burnaby, or a warehouse buildout in Surrey, the questions to ask contractors before signing anything are your first and best line of defense. A few targeted questions during the interview phase reveal far more about a contractor's reliability than their website ever will.

1. Are you licensed, insured, and bonded?
This is the first and most non-negotiable contractor vetting question. Every legitimate contractor should be able to show you proof on the spot. Licensed and insured contractors in Metro Vancouver must meet local regulatory requirements, and that documentation protects you from financial exposure if something goes wrong on your property.
Insurance covers property damage and on-site injuries. Bonding provides financial protection if a contractor abandons your project before completion. Without both, you could be held liable for accidents that happen on your own property.
Ask these questions directly:
- Can you provide a current copy of your contractor license?
- What does your liability insurance cover, and what is the policy limit?
- Are you bonded, and for how much?
- Is your WorkSafeBC coverage current? (For projects in British Columbia)
Pro Tip: Don't just accept a verbal yes. Call the insurer directly to verify the policy is active and your project is covered.
License, insurance, and bonding establish accountability if issues arise during or after construction. A contractor who hesitates or stalls when asked for documentation is a red flag.
2. Who handles permits and inspections?
Permits are not a formality. They are legal documents that protect you as the property owner. Some jurisdictions require the contractor to pull permits, and the timing of inspections directly impacts key project milestones like rough-in framing, electrical, plumbing, and final sign-off.
In Metro Vancouver, cities like Richmond, Coquitlam, and Surrey each have their own building departments with specific requirements. You need to know who takes ownership of the permit process before work begins. If a contractor expects you to manage permits yourself without explaining why, ask more questions.
Understanding how contractors handle permits in your specific municipality is worth the time before any contract is signed. Delays at the permit or inspection stage are one of the most common causes of project overruns, and most of them are preventable.
3. What similar projects have you completed recently?
General experience is not the same as relevant experience. A contractor who has built 20 custom homes may not be the right fit for a commercial retail buildout in Richmond or a coffee shop renovation in Coquitlam. Experience with projects similar to yours predicts how smoothly execution will go far more accurately than years in business.
When you ask this contractor interview question, you're looking for scope match, not just industry match. A tenant improvement project in an occupied office building has different constraints than a ground-up residential build. Ask specifically:
- Can you show me photos or a portfolio of projects comparable to mine?
- How recently did you complete a project of this type?
- What were the specific challenges on that project and how did you resolve them?
Relevant project references offer clearer insight into contractor capabilities than general portfolios. A contractor who can speak in detail about solving a specific problem on a past project similar to yours is far more credible than one who hands you a glossy brochure.
4. Can I speak with recent references?
References are one of the most underused tools in contractor vetting. Most homeowners ask for them and then never follow through. That's a mistake. Recent references from similar projects reveal communication style, schedule adherence, problem-solving under pressure, and how the contractor handled disputes or surprises.
When you call a reference, don't just ask "were you happy with the work?" Dig deeper. Ask whether the project finished on time, whether the final cost matched the estimate, whether the site was kept clean and safe, and whether they would hire this contractor again for a larger project. Customer testimonials and direct references together give you a much fuller picture of what working with a contractor actually looks like day to day.
Pay attention to what references don't say. Hesitation, short answers, or a redirect to "just look at the finished photos" can be telling.
5. Who manages the day-to-day work on site?
This is one of the most important questions for hiring contractors that gets skipped most often. The person you interview is not always the person running your project. On larger jobs, a project manager or site superintendent takes over once the contract is signed. Naming the daily site manager and clarifying their role is how you maintain accountability from day one.
Ask these questions to get clarity:
- Who is my main point of contact once work starts?
- Will a project manager or site superintendent be on site daily?
- How do you prefer to communicate: phone, email, or a project management app?
- How quickly do you typically respond to questions or concerns?
- What happens if that site manager becomes unavailable mid-project?
Frequent, clear communication keeps projects on track and reduces anxiety during construction. The best contractors have a clear answer for every one of these questions before you even finish asking.
Pro Tip: Ask for a sample of how they communicate with clients on active projects. A weekly update email, a shared photo log, or a scheduling app are all signs of a contractor who runs a professional operation.
6. Which subcontractors will you use and how do you manage them?
Most general contractors use subcontractors for specialized trades like electrical, plumbing, HVAC, and millwork. That's standard and expected. What matters is how they manage those subcontractors and who takes responsibility for their work quality. Understanding subcontractor roles in Vancouver construction helps you ask the right follow-up questions.
For subcontractor-heavy projects, naming the daily site manager and clearly defining subcontractor responsibilities mitigates quality and scheduling risks. A general contractor who has long-standing relationships with their trades has a real advantage here. Ask whether subcontractors are licensed and insured independently. Ask how conflicts between trades are handled on site. Ask who you contact if a subcontractor's work needs to be corrected.
The answers tell you a lot about how tightly the project will be managed from start to finish.
7. What does your written estimate include and exclude?
A verbal price is not an estimate. A true written estimate breaks down every cost line by line: labor, materials, permits, subcontractor fees, equipment rentals, and site cleanup. Incomplete estimates and unclear change order processes are among the most frequent sources of cost overruns and disputes in residential and commercial construction alike.
The table below shows the difference between a strong estimate and a weak one:
| Feature | Strong estimate | Weak estimate |
|---|---|---|
| Labor costs | Itemized by trade and hours | Lumped as one total |
| Materials | Specified by product and quantity | Listed as "materials TBD" |
| Change order process | Written process with approval steps | Handled verbally as needed |
| Exclusions | Explicitly listed | Not mentioned |
| Contingency | Stated percentage or amount | Not included |
When reviewing what to ask a contractor about cost, also ask:
- How are change orders priced and who approves them?
- What triggers a change order on your projects?
- Are subcontractor costs included in this estimate or billed separately?
Contracts should include detailed line-item estimates and a formal change order approval process to reduce scope creep disputes. If a contractor gives you a single number with no breakdown, ask again.
8. What is the payment schedule and what warranty do you offer?
Payment schedules tied to project milestones protect you from paying for work that hasn't been done. Milestone-based billing prevents large upfront deposits and keeps both parties accountable to the project timeline. A common structure covers deposit, framing completion, rough-in sign-off, substantial completion, and final holdback.
Watch for these red flags in payment discussions: demands for more than 10 to 15 percent upfront, requests for cash payments only, or no clear connection between payment and verified progress.
On the warranty side, warranties typically cover at least one year for labor and installed materials and should specify the claims process clearly. Ask who handles a warranty claim if a subcontractor's work is at issue. Also ask about lien waivers. A contractor who understands lien waivers and includes them in their process is protecting both parties and demonstrating professional standards.
My take on what actually separates good contractors from great ones
I've reviewed hundreds of contractor relationships over the years, and the single biggest factor in project success isn't the lowest bid or the flashiest portfolio. It's documentation and communication working together before the first nail goes in.
In my experience, most disputes don't start at the end of a project. They start in the first two weeks, when assumptions that weren't discussed in the interview phase become expensive misunderstandings on site. I've seen projects in Burnaby and Richmond go sideways not because of incompetence but because no one asked who owned a specific decision when conditions changed.
Structured, documented joint reviews during project phases help manage change orders and avoid disputes. I'd go further: schedule your first review before construction begins. Walk through the contract together, page by page. It sounds slow. It saves weeks.
The contractors who welcome that kind of rigor are the ones worth hiring. The ones who resist it are telling you something important.

FAQ
What are the most important questions to ask contractors?
Ask about licensing, insurance, bonding, recent comparable references, who manages the site daily, and how change orders are priced and approved. These questions cover legal protection, reliability, and financial transparency in one pass.
How do I verify a contractor's license in British Columbia?
You can contact BC Housing's Licensing and Consumer Services division to confirm a contractor's license status. Always request a copy of the license and insurance certificate directly from the contractor as well.
What should a written contractor estimate include?
A written estimate should itemize labor by trade, specify materials by product and quantity, list permit fees, name subcontractor costs, state exclusions explicitly, and include a change order approval process. A single lump-sum number is not a sufficient estimate.
How should contractor payments be structured?
Payment schedules tied to milestones are the safest structure. Expect a modest deposit of 10 to 15 percent, with subsequent payments tied to verified stages like framing, rough-in approval, and substantial completion. Avoid large upfront payments not connected to progress.
What is a change order and why does it matter?
A change order is a written amendment to the original contract scope or price. Without a formal change order process, verbal agreements about additions or modifications frequently lead to disputes over cost and responsibility at the end of a project.
