    Home Renovation Contractor in Markham, ON

    Kitchens, bathrooms, basements, and additions — completed by a team based just next door in Richmond Hill.

    Just next door to our home base in Richmond Hill, Markham is one of the most active renovation markets in the GTA — a mix of established mid-century homes ready for a full kitchen or basement overhaul, and newer builds where homeowners are adding space rather than moving. Oborne Contracting has been renovating Markham homes for over 25 years, and our proximity means faster site visits, faster quotes, and a team that’s genuinely familiar with the area.

    Frequently Asked Questions

    Do I need a permit to renovate my home in Markham?

    The City of Markham requires permits for most structural work, additions, and many basement renovations. We assess what’s needed for your project during the consultation and handle permit coordination as your general contractor.

    How long does a typical renovation take in Markham?

    Timelines depend heavily on scope — a bathroom refresh moves much faster than a full home addition. We provide a realistic project timeline as part of your quote so you know what to expect before work starts.
