  • Foundation Repair Specialist in Thornhill, Ontario

    From pool openings and closings to demolition and foundation waterproofing — I do it all. I’m a versatile handyman serving the Greater Toronto Area with experience spanning landscaping construction (interlock, pavers, retaining walls), roofing repairs, drywall, carpentry, concrete work, fencing, garage doors, painting (interior/exterior), window and door installations, light electrical, plumbing fixtures, appliance installs, pressure washing, pool maintenance, junk removal, gardening, welding, and pretty much everything in between. My skills come from the ground up. My father is a condo developer in Mongolia — I grew up on job sites, watching and doing real construction work from a young age alongside experienced crews. That hands-on upbringing, combined with my Civil Engineering Technology diploma and current studies toward a Civil Engineering degree at McMaster University, means I bring both deep practical skill and technical knowledge to every job. I’m 30, reliable, have my own vehicle, and will show up on time. I’m trilingual in English, Russian, and Mongolian, and I work with integrity — if I’m ever unsure about something, I’ll say so and figure it out properly rather than guess. No shortcuts, no excuses. Do it once and right

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.
