Basement underpinning in Etobicoke can create more usable ceiling height or strengthen a foundation affected by settlement, cracking or movement. MAGCOR manages engineering, permits, staged excavation, structural reinforcement and waterproofing where required. With our office at 82 Advance Rd., we are based in Etobicoke and work throughout the area. Request a free on-site assessment and project quote.
Underpinning isn’t a standard renovation job. It’s structural work under a house that’s still standing, so the underpinning contractor you hire matters.
We’re an Etobicoke company ourselves. Our corporate office is at 82 Advance Rd., so most jobs in the area are close to home.
We cover the full range of basement lowering and foundation work for Etobicoke homes. Our basement underpinning services page lays out the complete scope.
Dropping the floor turns a basement you duck through into a room you can actually use. The extra headroom opens the door to a rec room, a home office, an additional bedroom, or another permitted use.
We extend and strengthen the existing foundation to deal with settlement, aging materials, and structural concerns, rather than patching symptoms at the surface.
Where conditions allow, a shallow crawl space can be excavated and turned into proper below-grade space.
When traditional underpinning isn’t the right call, bench footing lowers the floor while leaving the existing footing untouched. It costs you some perimeter floor space in exchange.
Drainage, waterproofing membranes, crack repair, and reinforcement get folded into the same scope when the project calls for them.
We start in your basement, not on paper. Our team reviews the existing foundation and slab, talks through the ceiling height you’re after and what you plan to do with the space, then flags anything structural, moisture-related, or access-related that shapes the approach.
Structural drawings and engineering requirements get coordinated next, then submitted for the City of Toronto building permit. Inspections are scheduled and the excavation sequence is approved before anyone breaks ground. If you want the full picture first, our guide to how basement underpinning works covers the process and timeline.
The old slab comes out where required, and we excavate beneath the foundation in short, numbered sections. New reinforced concrete footings go in one section at a time, and each pour has to reach strength before the next section opens up. Our excavation services crew handles the dig and the haul-off.
With the foundation exposed, drainage is easier to address than it will ever be again. Membranes, weeping tile, sump systems, and other moisture control go in where the site needs them. We also account for plumbing and drainage elevations once the floor sits lower.
Required inspections are completed, the new slab and related structural components go in, and the work area is cleaned. You get the basement back ready for the next trade.
Most of the signs turn up slowly. Low ceiling height is the obvious one, since it caps what the basement can ever be. Foundation cracks, uneven floors, and visible movement in the walls point to something structural. Recurring dampness or water after heavy rain belongs on the list, along with aging foundation materials, a basement renovation on the horizon, or structural upgrades needed for work upstairs.
None of that automatically means underpinning. Some of these issues have simpler fixes, and a few common planning mistakes start with assuming otherwise. A professional foundation assessment tells you which solution fits.

Older homes tend to come with foundations that suited the era they were built in and not much beyond it. Shallow footings, low headroom, older concrete or masonry, and a basement laid out for storage rather than living. Underpinning deepens the foundation and gains ceiling height in the same pass.
What matters is the assessment. Existing footing depth, foundation condition, soil and groundwater on the lot, nearby structures, and any shared or closely spaced foundations all shape what’s achievable and how the excavation has to be staged.
Start Your Demolition ProjectLowering a basement changes how the floor, foundation, drainage system, and surrounding groundwater interact. Going closer to the water table without a water plan is how a new basement ends up damp.
Underpinning is the practical time to handle it, since the foundation is already exposed. Depending on the site, that means waterproofing membranes, new weeping tile, drainage upgrades, sump pump integration, crack repair, and moisture protection under the new slab. The right scope comes from your site conditions, not a standard package.

It depends on basement size, excavation depth, foundation condition, site access, engineering, and waterproofing scope. An on-site assessment is the only way to price it accurately.
Yes. Structural underpinning normally requires engineered drawings, a City of Toronto building permit, and inspections. We coordinate the documentation and the process for you.
Timelines vary with basement size, underpinning depth, site access, structural requirements, inspection scheduling, and any added waterproofing or drainage work.
Yes. Lowering the floor through underpinning increases floor-to-ceiling height and makes the space workable for a proper basement renovation.
Yes, and it’s usually the sensible time to do it. Weeping tile, sump systems, drainage upgrades, and moisture protection go in more easily while the foundation is open.
