    Frequently Asked Questions

    Does Thornhill fall under Vaughan or Markham permitting?

    Thornhill spans both municipalities, so permit requirements depend on which side of the border your home is on. We confirm the correct jurisdiction and handle permit coordination as part of your project.

    Do you work on older, character homes in Thornhill?

    Yes — a large share of our Thornhill projects involve renovating established homes, from updating outdated kitchens and bathrooms to adding square footage while keeping the home’s original character intact.
