Concrete Repair in Toronto & the GTA: Crack Repair, Lifting, Foundation Repair, Cutting & Sealing
Repair is the part of the business we are known for. Toronto clay soil, freeze-thaw cycling and road salt do predictable damage, and most of it can be fixed for far less than a tear-out. We inject cracks, lift sunken slabs with polyurethane foam, waterproof and stitch foundations, cut clean openings for trades, build retaining walls, and seal concrete before the next winter gets at it.

What Customers Say About Our Repair & Specialty Concrete Work
Real feedback from Toronto and GTA homeowners on completed concrete work.
"They came out within two hours of my call and gave me a written quote on the spot. Half the contractors wanted to replace my whole driveway, but Best Concrete lifted and resurfaced it for a fraction of the price. Honest and fast."
"Our front porch was crumbling from years of salt. They stitched the cracks, redid the coping, and resurfaced it so it looks new. The pricing was published up front with no surprises."
"We needed a warehouse floor poured on a tight schedule. The crew hit the flatness numbers and the forklifts were running the following week. Fully insured and professional."
"The stamped concrete patio they poured is stunning and still looks great after a Toronto winter. They explained the sealing schedule and honoured the warranty when I had a question."
"Polished the concrete floor in our basement and it transformed the space. Dust was kept to a minimum and they finished in the days they promised."
Repair & Specialty Concrete Questions We Get Asked
Should I repair or replace my concrete driveway?
Often you can repair. About half the driveways called in for replacement can be repaired at roughly 40 percent of the cost through crack repair, lifting, or resurfacing. If the slab is heaved, badly spalled, or sitting on a failed base, replacement is the better long-term choice. We assess and tell you honestly.
How much does concrete lifting cost vs replacement?
Lifting a sunken slab costs $6 to $12 per sq ft, often a fraction of full replacement. When the concrete itself is sound and only the base has settled, lifting is the smart choice. If the slab is cracked through or crumbling, replacement is better value long term.
What is the difference between mudjacking and polyurethane foam lifting?
Mudjacking pumps a cement slurry under the slab to raise it, while polyurethane foam injects a lightweight expanding foam. Foam is lighter, cures in minutes, and resists re-settling in Toronto clay soil, where heavy slurry can sink again. We recommend foam for most GTA jobs.
How long does concrete last?
Well-installed, sealed concrete lasts 25 to 40 years or more in the GTA. Freeze-thaw cycles and road salt are the main enemies; regular sealing and prompt crack repair are what stretch a slab to the top of that range.
What is your warranty on concrete repair?
Every installation, including repairs, carries our 2-year workmanship warranty. We are licensed, WSIB-insured, and carry $2M general liability, so the work is backed and covered.
