Ivo Gonzalez-Vucina, Full Home RenovationFrequently Asked Questions
Everything you'd ask before committing.
In the Toronto market, the highest return comes from projects that increase functional square footage or improve energy efficiency. Legal basement suites are the top value-adder given Toronto's housing demand. Kitchen refreshes (new counters, cabinet refacing, efficient appliances) often outperform a full luxury gut. Bathroom upgrades, especially adding a second bathroom, significantly boost resale appeal. Heat pumps, triple-pane windows, and better insulation are increasingly attractive to buyers facing rising utility costs, and a new front door or updated landscaping offers a lot of impact for a relatively small spend.
A full house renovation typically runs $150 to $450 per square foot depending on the home's age and finish quality. For a standard 1,500 sq ft detached home, budget $200,000 to $600,000+. Basic/cosmetic work (no wall moves) runs $150 to $200 per sq ft, mid-range (layout changes, custom cabinetry, upgraded electrical/plumbing) runs $200 to $350, and a high-end full gut with structural changes and luxury finishes runs $350 to $500+. Factor in 13% HST, City permit fees ($2,000 to $10,000+ for major work), and a 15% contingency for the surprises common in older Toronto homes.
A cosmetic refresh runs 1 to 2 months. A kitchen or bathroom remodel runs 3 to 5 months, largely because custom cabinetry carries 8 to 12 week lead times. Basement finishing runs 4 to 6 months, longer if it's a legal secondary suite or needs underpinning. A full house gut or major addition runs 9 to 15+ months given the architectural drawings and structural permits involved. Budget 3 to 6 months before construction even starts for design and City approvals, and add another 3 to 5 months if your project needs a Committee of Adjustment hearing.
Set up a mini-kitchen in a clean room (microwave, coffee maker) if your kitchen's affected. Move furniture and breakables out of the work zone ahead of time. Confirm your contractor uses plastic sheeting and HEPA filters to keep dust out of the rest of your home.
Skipping the contingency fund: mould or faulty wiring often hides behind walls, so set aside an extra 10 to 20% of your budget. Hiring solely on price, since the lowest bid often reflects missing insurance or hidden fees. Changing your mind mid-project, which is the most common timeline killer: finalize fixtures and floor plans before work starts. Over-improving for the area if you plan to sell. Neglecting your electrical layout early, and leaving structural, plumbing, and electrical work to licensed pros rather than DIY-ing it.
For a targeted renovation (a bathroom, kitchen, or basement), yes, most homeowners stay, and we keep the unaffected areas clean and liveable. For a full home renovation, some homeowners choose to relocate temporarily. We give you an honest read on disruption during planning, before you sign anything.
It depends on scope. Cosmetic work like painting, flooring, and cabinet swaps usually doesn't need one. Structural changes, wall removals, electrical upgrades, plumbing moves, and envelope changes require a City of Toronto building permit. We assess this for every project and manage the full application on your behalf.
Yes. Where a permit's required, we assess whether one's needed, prepare and submit the application, produce structural drawings where required, coordinate City inspectors through construction, and get final sign-off at completion.
