Your Basement Doesn’t Have to Feel Like a Cave
Most Toronto basements were built as an afterthought, with low ceilings, damp air, and square footage nobody uses. WillFix changes that through basement underpinning: digging under your foundation section by section, pouring new concrete and prepping it for finishing.
We manage all the permits, engineering, inspections, and every stage of construction ourselves. Your part is simple: give us access to the basement and the areas where we’re working. We handle the other 95% of the work, so your new space gets built without turning your home upside down.
Numbers Don’t Lie: Why Homeowners Choose WillFix
Choosing WillFix as your basement underpinning Toronto company means peace of mind, knowing that your home’s foundation is in expert hands. Protect your investment and let the WillFix difference make your underpinning basement a dry, comfortable space.

Exclusive Senior Discount
A settling or leaking basement doesn’t just damage concrete. It puts everything above it at risk, from your walls to your family’s safety. That’s why every WillFix basement underpinning project includes a full check of your plumbing, wiring, and other systems below the floor. We catch small problems while they’re still small, before they turn into expensive ones.
Homeowners aged 65 and older shouldn’t have to choose between a safe foundation and a comfortable budget. As a thank you for the trust so many seniors have placed in us over the years, WillFix offers a 5% discount on all services for clients 65 and up. Contact us today to see how much you could save.
Toronto Will Pay You Back Up to $6,650
When we underpin your basement, we’re already digging deep enough to run new plumbing, waterproofing, and drainage, the same work the City of Toronto rewards through its Basement Flooding Protection Subsidy Program. Homeowners can now claim up to $6,650 per property to cover 80% of the cost of a backwater valve, a sump pump, a home plumbing assessment, or a weeping tile disconnection.
Since our crew is already below your floor, adding these upgrades during underpinning costs far less than installing them later, and you have two years to apply. WillFix helps you figure out which upgrades apply and handles the City paperwork, so you walk away with a stronger foundation, a drier basement, and real money back.

Basement Underpinning Toronto FAQ
-
How long does basement underpinning take in Toronto?
Most projects take 6 to 12 weeks from start to finish, depending on your basement size and the depth required. Larger projects involving several foundation sections can take longer. We'll give you a realistic timeline once we've assessed your home.
-
Is basement underpinning safe for my house?
Yes, when it's done by licensed professionals following proper engineering plans. We work in small sections at a time, so your foundation stays supported throughout, and a certified engineer signs off on every stage.
-
Do I need a permit for basement underpinning in Toronto?
Yes, the City requires permits for any underpinning project since it changes your home's foundation. WillFix handles the entire process, including engineering drawings and inspections, so you don't have to deal with City Hall yourself.
-
Does basement underpinning actually increase my home's value?
In most cases, yes. A properly underpinned, finished basement adds real usable square footage, and Ontario homeowners typically recover a solid share of the cost at resale. We break down the numbers in our guide to basement value in Ontario.
-
Can I turn my crawl space into a full basement?
Absolutely. Crawl space excavation is one of our most requested services, and it can turn a cramped, unusable space into a full basement with standard ceiling height. See our guide to crawl space to basement conversions for the full process and cost breakdown.
-
Why does my basement keep getting damp even after waterproofing?
Often, the problem starts outside your home, not inside it. Poor soil grading around your foundation lets water pool against your walls instead of draining away. Our post on the best soil types for grading around your house covers how to fix this before it becomes a foundation problem.
-
Can I finance my basement underpinning project?
Yes. WillFix partners with Financeit to offer flexible monthly payment plans, so you don't need the full project cost upfront. Learn more about eligibility and how to apply on our financing page.
