When planning a home addition in Toronto, whether it’s a second story, a kitchen extension, or a new family room, choosing a home addition contractor is the most critical decision. I’m Nima, a contractor with experience on projects from small additions in East York to full rear extensions in Mississauga. I’ve seen the consequences of homeowners skipping key questions—delays, legal issues, and unfinished work can be devastating.
Here are seven essential questions to ask when choosing a home addition contractor in Toronto or the GTA to protect your home, budget, and peace of mind.
1. Are You Licensed and Insured to Work in Toronto?
Why It Matters:
Only licensed contractors can legally build home additions in Toronto and surrounding areas. A license ensures familiarity with building codes and municipal regulations. Insurance protects you from liability if accidents occur.
Ask This:
- Are you licensed by the City of Toronto?
- Do you carry at least $2 million in liability insurance and WSIB coverage?
Pro Tip:
Request proof of insurance. When choosing a home addition contractor, a reliable one will provide an insurance certificate within 24 hours. If they hesitate or suggest a “cash deal” to avoid permits, walk away.
2. Can You Show Me Similar Home Additions You’ve Done in the GTA?
Why It Matters:
Each neighbourhood has unique rules, such as heritage restrictions, zoning bylaws, and lot setbacks. Choosing a home addition contractor with local experience ensures they understand these nuances.
Ask This:
- Have you worked in this neighbourhood or municipality before?
- Do you have photos of similar projects?
Pro Tip:
If they can’t provide examples, they may lack experience with your type of project. Ask to visit a past project—seeing work in person reveals more than online photos.
3. Do You Provide References from Past Clients?
Why It Matters:
Speaking with previous clients reveals whether the contractor stayed on budget, met deadlines, and resolved issues effectively.
Ask This:
- Can I speak with 2–3 homeowners you’ve worked with in the last year?
Pro Tip:
When choosing a home addition contractor, pay attention to how they handled challenges. No project is flawless, but great contractors address issues without excuses.
4. Who Will Be Managing My Project—and How Will You Communicate With Me?
Why It Matters:
You’re hiring a team, not just one person. Knowing who’s overseeing the project and how updates will be shared ensures clarity.
Ask This:
- Will I have a dedicated project manager?
- How will I receive weekly updates—email, texts, or in-person meetings?
Pro Tip:
Avoid contractors who rely solely on vague texts. Clear communication is key when choosing a home addition contractor to prevent surprises.
5. What’s the Timeline—and How Do You Handle Delays?
Why It Matters:
Permits, weather, and inspections can cause delays, but a professional contractor plans ahead and keeps you informed.
Ask This:
- What’s the estimated timeline from permits to final inspection?
- How do you manage delays?
Pro Tip:
Request a written timeline with phases: design, permits, excavation, framing, and finishing. Be wary of promises of “no delays”—no one can guarantee that in construction.
6. Can I See a Sample Contract Before We Start?
Why It Matters:
A clear contract protects both you and the contractor, preventing disputes. It should detail the scope of work, payment structure, change orders, project costs, and coordination with architects or zoning regulations.
Ask This:
- Can you provide a sample contract?
Pro Tip:
When choosing a home addition contractor, ensure the payment plan is fair, supports ongoing work, and is documented. Agree on fixed prices for changes in writing before proceeding.
7. Do You Provide a Warranty, and What’s Your Customer Service Like After Completion?
Why It Matters:
Even high-quality work can have issues, like drywall cracks or sticking doors. A warranty ensures the contractor addresses post-project problems.
Ask This:
- What kind of warranty do you offer for labor and materials?
- How long is the warranty
