FAQ: Common questions about foundation repairs in Thornhill, Ontario

How long do foundation repair projects in Thornhill, Ontario take?

The timeline depends on the type and scale of repair needed. Crack injections can often be completed in a single day, while more involved work such as underpinning or full perimeter drainage installation may take several days to a few weeks. Weather conditions and site accessibility around your Thornhill, Ontario home can also affect the schedule.

Do foundation repair projects in Thornhill, Ontario come with a warranty?

Many foundation repair companies offer warranties on their work, and some manufacturers also provide product warranties on materials like carbon fibre straps or drainage systems.

Do foundation repairs require a permit in Thornhill, Ontario?

Permit requirements vary by municipality, but structural work such as underpinning typically requires a building permit, while smaller repairs like crack injection often do not.
