How much does whole-home renovation cost in Newmarket?

With Zigma Group, whole-home renovation starts from $105 per sq ft. Prices are in Canadian dollars before HST, as of October 2026, and are confirmed after a site visit. The main factors are how much of the house is taken back to the studs; replacing wiring, plumbing and heating; and structural changes and finish level.

Is it better to renovate the whole house at once or room by room?

Doing it as one project lets the wiring, plumbing, insulation and structure be fixed while the walls are open, and avoids redoing finished rooms later. Room-by-room work can suit a smaller budget, but each phase repeats the setup and disruption.

Do I need a permit for a whole-home renovation in Ontario?

Almost always. Structural changes, new or moved plumbing, heating changes and additions need a building permit, and electrical work must be filed with the Electrical Safety Authority. Requirements vary by municipality, so we confirm them for your address.

Do you do whole-home renovation projects in Newmarket?

Yes. We work throughout Newmarket, including Glenway, Stonehaven, Summerhill, Bristol-London and Historic Main Street. Call +1 (647) 718-3913 to arrange a visit.

Who issues the permit for this work in Newmarket?

Where a permit is needed, it is issued by the Town of Newmarket's building services. We prepare the drawings and handle the application and inspections.

Whole-Home Renovation in Newmarket

A whole-home renovation rebuilds the house you already own: new layout, new systems and new finishes, planned as one project instead of a string of separate jobs. In Newmarket, the housing ranges from century homes near Main Street to subdivisions built from the 1970s to the 2000s.

What to know.

Permits
Moving walls, changing structure or altering plumbing and heating usually needs a building permit in Ontario. We prepare the drawings and handle the application with your municipality.

A full renovation touches every room, so most families move out for the main construction period. We set the sequence with you before work starts.
