How much does a renovation cost in Newmarket?

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 Newmarket?

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 Newmarket 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 across Newmarket's older and newer homes alike.

Which Newmarket neighbourhoods do you work in?

All of them. We renovate homes across the Old Town, Bristol-London, Gorham-College Manor, Huron Heights, Stonehaven, Summerhill, Glenway and Woodland Hill — from century heritage homes to the town's newer builds. We serve Newmarket daily from nearby Richmond Hill and Aurora.

Why choose GMC over other Newmarket 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 Newmarket?

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 Newmarket's Building Division. Heritage properties in the Old Town may need additional approval for exterior work. 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 Newmarket

When it comes to home renovation Newmarket, no two homes are alike — from the character houses near historic Main Street to the executive properties of Stonehaven and the newer homes of Summerhill and Glenway, each has its own character. GMC Construction Inc. has spent 15+ years working across all of them — kitchens, bathrooms, basements and whole-home renovations for Newmarket 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 Newmarket renovation company offers.

Renovating in Newmarket: What to Know

Newmarket’s housing stock ranges from genuinely historic to brand new. The century homes and character properties around Main Street and the Old Town are full of charm but often need careful updating of layouts, wiring, plumbing and insulation — and exterior work in a heritage area comes with additional review. The established homes of Bristol-London, Gorham-College Manor and Huron Heights are prime candidates for kitchen open-ups, basement suites and second-storey additions. The newer homes of Summerhill, Glenway, Woodland Hill and Stonehaven are larger and more open, where the work is usually finishing a basement, building a custom kitchen, or adding a spa-style ensuite.

Basement-finishing and secondary-suite projects are especially common across Newmarket’s family neighbourhoods — turning a large lower level into legal living space or a rental suite. These involve proper permits and careful structural and drainage planning that a structure-first contractor gets right up front.

Do You Need a Permit to Renovate in Newmarket?

Renovation permits in Newmarket are issued by the Town of Newmarket’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, altering electrical, removing a load-bearing wall, finishing a basement, adding a legal second suite, or building an addition typically do. Heritage properties in the Old Town may require additional approval for exterior work. As a licensed contractor, GMC manages the permit process for you and arranges the stamped structural drawings your project requires.

Newmarket also permits Additional Residential Units — basement apartments and secondary suites — subject to the Town’s zoning by-law and a building permit, within the York Region framework. A legal suite must meet the Ontario Building Code and Fire Code, including a minimum ceiling height of about 6 ft 5 in (which may call for underpinning where the basement is too shallow), egress, and fire separation; electrical work requires a separate permit from the Electrical Safety Authority (ESA). Older homes near the historic Main Street heritage district may also carry heritage review for exterior work, which we flag early so it never becomes a mid-project surprise.
