How much does a renovation cost in Scarborough?

It depends on scope and finishes. As a guide, bathroom renovations typically run $15,000–$27,000, kitchens $24,000–$58,000, and finished basements $33,000–$68,000, with legal suites, whole-home and addition projects quoted individually. After a free in-home consultation we give you a detailed, fixed-price quote — the real number, with no vague allowances.

How long does a renovation take in Scarborough?

Timelines depend on scope. A bathroom typically takes 3–6 weeks, a kitchen 4–8 weeks, and a basement 6–10 weeks, while whole-home renovations and additions run longer — especially when a Toronto Building permit is required, since municipal review adds time. We give you a week-by-week schedule before work begins so you always know what to expect.

Can you build a legal basement apartment in my Scarborough home?

Yes. Legal basement suites are one of the most common projects we do in Scarborough, where large bungalows are ideal for a separate lower-level apartment. GMC handles the Toronto permit, fire separation and egress — and because the owner holds a Master's degree in Structural Engineering, any structural changes are planned properly and, where required, backed by a licensed professional engineer's stamped drawings.

Which Scarborough neighbourhoods do you work in?

All of them. We renovate homes across Wexford, Bendale, Dorset Park, Agincourt, Milliken, L'Amoreaux, Cliffside, Birch Cliff and Guildwood — from postwar bungalows to lakeside homes near the Bluffs. We serve Scarborough across the whole district.

Why choose GMC over other Scarborough renovation companies?

GMC is led by an owner who holds a Master's degree in Structural Engineering, so every project is planned around how your home actually carries load — the structural surprises that stall other renovations get caught up front. Combined with fixed-price quotes, a written workmanship warranty, and a 5.0-star rating across 84 Google reviews, that gives you a level of confidence most renovation crews can't match.

Q: Do I need a permit to renovate my home in Scarborough?

Scarborough is part of the City of Toronto, so permits are issued by Toronto Building. Cosmetic updates — new cabinets, tile, fixtures or finishes in the same layout — usually don't need a permit. But moving plumbing, changing electrical, removing a load-bearing wall, finishing a basement, adding a legal second or garden suite, or building an addition require a Toronto Building permit, and additions may involve the Committee of Adjustment. As a licensed contractor, GMC handles the entire permit process for you.

Built to Last — Not Just Installed

What makes us different starts before the first material is ordered. GMC Construction is founded and led by an owner who holds a Master's degree in Structural Engineering — so every project is approached with a genuine, advanced understanding of structure, load-bearing changes, drainage, and moisture protection. Most renovation companies focus only on how a space looks. We start with what's underneath, because that's what determines whether your renovation lasts five years or twenty-five.

Renovation Contractors in Scarborough

When it comes to home renovation Scarborough, no two homes are alike — from the postwar bungalows of Wexford and Bendale to the family neighbourhoods of Agincourt and the lakeside homes near the Bluffs in Cliffside and Guildwood, each renovates differently. GMC Construction Inc. has spent 15+ years working across all of them — kitchens, bathrooms, basements and whole-home renovations for Scarborough homeowners who want the job planned properly, priced honestly, and built to last.

What sets us apart in a crowded market: GMC is led by an owner who holds a Master’s degree in Structural Engineering. Before we quote a wall removal, a basement underpinning, or a second-storey addition, we understand how the house actually carries load — which is why our projects don’t run into the structural surprises that stall other renovations. It’s a structure-first approach no other Scarborough renovation company offers.

Renovating in Scarborough: What to Know

Scarborough’s housing is dominated by solid postwar construction on generous lots, and that shapes most projects here. The bungalows, back-splits and side-splits of Wexford, Bendale, Dorset Park and Agincourt are structurally sound but often have compartmentalized 1950s–70s layouts — which makes them ideal for opening up the main floor, adding a second storey, or finishing the basement into a legal suite. The lakeside homes near the Bluffs in Cliffside, Birch Cliff and Guildwood carry more character and sometimes grading considerations near the escarpment. Across the district, generous lot sizes make additions and garden suites genuinely feasible.

Legal basement suites are especially in demand in Scarborough, where large bungalows lend themselves well to a separate lower-level apartment. These projects require proper permits, fire separation and structural planning — exactly the work a structure-first contractor gets right up front.

Do You Need a Permit to Renovate in Scarborough?

Scarborough is part of the City of Toronto, so renovation permits are issued by Toronto Building. Cosmetic work — replacing cabinets, tile, fixtures and finishes in the same layout — generally doesn’t require a permit. But moving plumbing, altering electrical, removing a load-bearing wall, finishing a basement, adding a legal second suite or garden suite, or building an addition typically do, and additions may involve the Committee of Adjustment. As a licensed contractor, GMC manages the Toronto permit process for you and works with a licensed professional engineer for any stamped structural drawings your project requires.
