How much does a renovation cost in Richmond Hill?

It depends on scope and finishes. As a guide, bathroom renovations typically run $16,000–$28,000, kitchens $25,000–$60,000, and finished basements $35,000–$70,000, with 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 Richmond Hill?

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 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 remove a load-bearing wall in my Richmond Hill home?

Yes — and this is where our approach stands apart. GMC is led by an owner who holds a Master’s degree in Structural Engineering, so we assess how your home carries load before touching a wall, and arrange the stamped structural drawings and permit the work requires. Opening up a closed layout is one of the most common — and most structurally sensitive — requests we handle.

Which Richmond Hill neighbourhoods do you work in?

All of them. We renovate homes across Mill Pond, Bayview Hill, South Richvale, Oak Ridges, Jefferson, Crosby, Harding, Observatory, Westbrook and the rest of Richmond Hill — from established two-storeys and bungalows to newer estate homes. We’re based right here in Richmond Hill at 75 Oneida Crescent.

Why choose GMC over other Richmond Hill 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 Richmond Hill?

It depends on the work. 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 suite, or building an addition require a permit from the Town of Richmond Hill’s Building Division. As a licensed contractor, GMC handles the entire permit process for you, and arranges the stamped structural drawings your project requires.

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 Richmond Hill

Richmond Hill homes are as varied as the town itself — established two-storeys in Mill Pond and Bayview Hill, custom estates in South Richvale, newer builds across Jefferson and Oak Ridges, and the mature bungalows and side-splits that fill Crosby, Harding and Observatory. Each era and neighbourhood renovates differently, and GMC Construction Inc. has spent 15+ years working across all of them. We deliver kitchen, bathroom, basement and whole-home renovations for Richmond Hill 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 Richmond Hill renovation company offers.

Renovating in Richmond Hill: What to Know

Richmond Hill’s housing stock spans nearly every era, and each brings its own renovation realities. The established homes around Mill Pond and Bayview Hill are solidly built but often have closed-off layouts and original wiring or plumbing due for updating. The bungalows and side-splits of Crosby, Harding and Observatory are prime candidates for kitchen open-ups, basement suites and second-storey additions. Newer homes in Jefferson, Oak Ridges and Westbrook tend to be larger and more open, where the work is usually finishing a basement, building a custom kitchen, or adding an ensuite.

Part of Richmond Hill also sits on the Oak Ridges Moraine, and homes near it can carry additional environmental and grading considerations for additions and major excavation — exactly the kind of detail a structure-first contractor plans for up front rather than discovering mid-project.

Do You Need a Permit to Renovate in Richmond Hill?

Renovation permits in Richmond Hill are issued by the Town of Richmond Hill’s Building Division, within the York Region framework. Cosmetic work — replacing cabinets, tile, fixtures and finishes in the same layout — generally doesn’t require a permit. But moving plumbing, adding or altering electrical circuits, removing a load-bearing wall, finishing a basement, adding a legal second suite, or building an addition typically do. As a licensed contractor, GMC manages the permit process for you and arranges the stamped structural drawings your project requires — so the work is done to code and passes inspection the first time.

Richmond Hill also permits Additional Residential Units (ARUs) — basement apartments and in-law suites — subject to zoning and a building permit. A legal suite must meet the Ontario Building Code, including a minimum ceiling height of about 6 ft 5 in (which may call for underpinning where the basement is too shallow), and electrical work requires a separate permit from the Electrical Safety Authority (ESA). We plan these projects to the city’s requirements from the start so they’re insurable and inspection-ready.
