Start With Referrals and a Shortlist of Contractors
Finding a reliable contractor starts before you ever request a quote. The best leads usually come from people who have already lived through a renovation. Ask neighbours, friends, and colleagues who recently finished a project. Ask them what went well, what went wrong, and whether they would hire the same crew again.
Referrals work well for three reasons:
Real results: You can see the finished work in person.
Honest feedback: A past client will tell you about delays, communication, and cleanup.
Local knowledge: Many referral sources have dealt with the same permit office and inspectors you will.
Watch out: A referral from a relative or close friend can be biased. Ask follow-up questions about the specific problems they faced.
Once you have referrals, build a shortlist of three to five contractors. Check each business's website, its project photos, and its online reviews. Cut any firm that cannot show recent work similar to your project, such as basement finishing or a full kitchen remodel.
Verify Licences, Registrations and Insurance
Before you sign anything, confirm that the contractor is properly licensed and insured. In Ontario, many trades require a licence or certificate (Skilled trades). Ask for copies of these documents, then verify them yourself rather than relying on what the contractor sends. You can read the MGH Renovations Privacy Policy to understand how personal information is collected, used, and protected.
Check these items for each contractor on your shortlist:
Business registration: Confirm the legal name matches the business on the contract.
Trade licences: Verify any licence needed for electrical, plumbing, or gas work with the issuing body.
Questions to Ask a Contractor Before Hiring
Your first conversations reveal a lot about how a contractor works, but a list of questions is only useful if you can compare the answers side by side. Prepare the questions below and note the answers in writing so your shortlist is based on evidence rather than gut feel.
The core questions
How long have you been running this business, and who will supervise my project day to day?
Can I see recent projects similar to mine, such as a basement finish or a kitchen remodel?
What is your process for providing a written estimate, and how do you handle changes?
Do you pull permits and book inspections, or do I need to arrange them?
What is your payment schedule?
How will we communicate during the project, and who is my main contact?
What happens if the project runs past the agreed timeline?
Pay attention to how clearly the contractor answers.

Contractor References and Past Work to Check
References tell you what a contractor is like to work with after the contract is signed. Ask for recent clients and call them rather than relying on emailed testimonials.

Reference questions that surface problems
Did the final cost match the original estimate, and if not, what changed?
Did the project finish on the agreed schedule, and how were delays communicated?
How was the daily cleanup and site protection?
Did the crew communicate problems early, or did you discover them later?
Were the subcontractors licensed and courteous?
Did the contractor handle permits and inspections, and did the work pass on the first inspection?
Would you hire this contractor again, and what would you change?

How to read online reviews critically
Online reviews are useful evidence, but only if you read them as a pattern rather than a score. Look for:
Clusters of similar complaints across multiple reviews, especially about timelines, change orders, or cleanup.
Detailed reviews that name the project type and the specific problem. https://www.mghrenovations.com/get-in-touch →
Responses from the business that address complaints professionally rather than defensively.
Recency: consider when the reviews were written.
Cross-check reviews against the contractor's own project photos.
Verify permits and inspections yourself
Ask the contractor which permits were pulled for a reference project. For your own project, confirm who is responsible for permits and inspections.
Next, review the work itself. Visit a finished project if the homeowner allows it. Look at grout lines, paint edges, and cabinet alignment. Patterns matter more than a single comment or a single photo.
How to Compare Contractor Quotes Without Chasing the Lowest Bid
Collect written quotes for the same scope of work. If two quotes differ, ask each contractor to explain the gap.
Compare quotes using a simple checklist:
Are the scopes of work identical?
Are allowances and exclusions clearly stated?
Does the quote include permits, inspections, and waste removal?
Is the payment schedule reasonable?
Does the warranty cover workmanship and materials?
