If you’re planning a major renovation, adding living space, or dealing with a sinking or unstable foundation, you need an underpinning contractor you can trust. At Kemper Concrete Inc., we provide reliable, code-compliant underpinning services across Southern Ontario, from the GTA through Hamilton, Haldimand County, and Niagara. Our team brings decades of combined experience and a reputation for workmanship that lasts.
We operate from our location at 1804 Hutchinson Rd, Dunnville, ON N1A 2W7, and you can reach us any time at (905) 577-3901 to discuss your project or request an estimate.
Underpinning strengthens or deepens an existing foundation. Homeowners and property managers often call us when:
They want to lower a basement floor for added ceiling height
The existing foundation shows signs of settlement or shifting
They plan to add another storey and need a stronger foundation
They’re converting an older structure into a more usable or rentable space
A proper underpinning job solves the problem at its source. The work supports the building from beneath, restores stability, and protects the structure for decades.
We’re specialists, not generalists: Underpinning isn’t a side service for us. It’s a major part of what we do, and our team understands the engineering and safety standards that keep your home secure.
We follow Ontario’s building codes and inspection requirements: We coordinate with engineers, follow all permit requirements, and complete each stage in a way that passes inspection without delays.
We focus on clean, safe jobsites: We keep work areas organized, secure, and accessible, even in tight basements and older homes.
We understand Southern Ontario soil and building conditions: From the GTA to Niagara, we know how local soil and moisture conditions affect foundations.
Clear communication from estimate to completion: We explain each stage in plain language so there are no surprises.
Lowering the basement floor through underpinning creates real living space for family rooms, rental suites, or finished basements.
If your home shows cracks, uneven floors, sticking doors, or signs of settlement, we investigate the cause and reinforce the foundation for long-term stability.
Adding a second storey or removing load-bearing walls often requires upgrading the foundation. We ensure your renovation rests on solid ground.
We safely prepare and support structures that require expanded basement access or additional excavation depth.
Kemper Concrete Inc. serves a wide stretch of Southern Ontario, including:
Toronto and the GTA
Mississauga, Brampton, Oakville, Burlington
Hamilton and surrounding areas
Haldimand County
St. Catharines, Welland, Niagara Falls, and the Niagara region
If you’re anywhere between the GTA and Niagara’s lakefront communities, we can help.
Every underpinning project starts with a site visit and assessment. Once the plan is approved, the process includes:
Section-by-section excavation around the existing footing
Pouring new concrete to extend or reinforce the foundation
Engineer inspections
Basement lowering if required
Backfilling, cleanup, and final checks
When done properly, your home ends up stronger than it was when first built.
A deeper, stronger foundation can:
Add usable square footage
Increase property value
Reduce moisture issues
Create space for legal basement apartments
Improve long-term stability and safety
