You might have heard or watched endless horror stories about homeowners being scammed by contractors. Sadly, that happens more frequently than you think but you should also know that doing research and picking a trusted general contractor is your responsibility. That includes doing your homework, managing your expectations according to your home renovation budget, and asking the right questions.
Here are 10 questions to ask before hiring a general contractor for major home renovation:
1. Can You Provide a Detailed Written Estimate?
A detailed written estimate document should break down all costs, including materials, labor, and any subcontractor fees. A transparent and itemized estimate helps you understand where your money is going and avoid any surprises down the line. A contractor who’s offering too many deliverables within your budget is also a huge red flag, so don’t always go with the cheapest estimate.
Ontario recommends at least three written estimates. The estimate should list the work, products, services, and prices. If the estimate becomes part of the contract, the final price generally cannot exceed it by more than 10 percent.
2. What Is Your Experience with Projects Similar to Mine?
Inquire about the contractor’s previous projects, especially those similar to yours. Ask for a portfolio or examples of recent work and see if they have the capability and expertise in handling projects like yours. At Your Kingston Contractor we specialize in modern, luxurious renovations and that’s highlighted through our projects.
3. Can You Provide References?
Don’t just take their word for it. Ask for references from past clients. Speaking to these clients can give you insights into the contractor’s work ethic, reliability, and quality of work.
Also consider the age of the references. A contractor who was great five years ago might have changed. Recent references are more reliable indicators of current work quality and business practices.
4. What Is the Expected Timeline for the Project?
Projects get delayed all the time, which could be due to labour or material shortage. Discuss the project’s start and end dates, and understand how the contractor plans to manage the timeline. Delays can be costly and frustrating, especially if the home you’re renovating is your primary residence.
Do not just ask for start and end dates. Ask about major milestones, material lead times, inspections, and circumstances that could delay the project.

5. How Will Project Changes Be Handled?
Renovations can change once walls open or homeowners make new selections. Ask how the contractor documents changes to scope, cost, and timing.
Ontario recommends documenting project changes in writing before additional work begins. This keeps expectations clear and gives both parties a record of approved changes.
6. What Is Your Communication Style and Frequency?
Set expectations when it comes to the general contractor’s communication style. As a client, you can request how often and through what means (email, phone, in-person) you will be updated about the project’s progress.
7. Who Handles Permits, Inspections and Code Requirements?
Major renovations may require building permits and inspections before work can proceed. Ask who will determine which permits apply and who will submit the applications.
In Ontario, the homeowner ultimately holds responsibility for required permits. A contractor can manage them on your behalf if the contract clearly assigns that responsibility.
The City of Kingston also requires inspections at specific stages of permitted work. These inspections confirm that construction meets applicable building requirements.
8. What Are the Terms of the Payment Schedule?
Review the payment schedule before signing the renovation contract. It should clearly state the deposit, payment amounts, and when each payment becomes due.
Ontario recommends keeping deposits to no more than 10 percent of the project cost. The province also advises homeowners against paying the full contract amount before completion.
For larger renovations, payments may correspond with agreed project stages. Make sure the complete payment schedule appears in your written contract.
9. Who Will Be On-Site Managing the Work Daily?
Major renovations often involve electricians, plumbers, HVAC specialists, carpenters, and other skilled trades. Ask who will coordinate these trades and oversee the work each day.
You should also know who serves as your main contact throughout the renovation. Ontario recommends identifying subcontracted trades and payment responsibilities within the renovation contract.
10. How Do You Handle Site Protection, Cleanup and Disposal?
Ask how the contractor will protect areas that remain in use during construction. This can include floors, cabinetry, furniture, landscaping, and adjoining rooms.
Discuss dust control, debris removal, daily site cleanup, and final disposal before work begins. Your contract should also state who handles cleanup once the renovation finishes.
11. Are You Insured?
Ask for proof of current insurance before hiring a general contractor. Appropriate liability coverage can provide protection if property damage or an accident occurs during construction.
You can also ask how the contractor handles insurance and workplace coverage for employees and subcontractors. WSIB requirements vary based on the contractor and type of residential renovation work.
