Our Story

Built for Toronto
Basements.

BaseWorks was founded by tradespeople who grew frustrated watching Toronto homeowners overpay for under-delivered basement work. Too many basement underpinning contractors in Toronto were operating without engineer-stamped drawings, pulling incomplete permits, and handing customers surprise invoices halfway through the job. Homeowners had no real way to distinguish a qualified contractor from someone working out of a van with a borrowed excavator.

We set out to build something different: a basement underpinning company defined by engineering first, permit compliance always, and a fixed price that doesn't shift once the contract is signed. That foundation - if you'll forgive the metaphor - is what BaseWorks stands on.

Today, BaseWorks is among the most experienced basement underpinning contractors serving Toronto and the GTA. We've lowered floors in century-old semis in Leslieville, reinforced crumbling foundations in post-war bungalows in North York, waterproofed Victorian rowhouses in Cabbagetown, and converted crawl spaces across Etobicoke. Every soil condition, every construction era, every neighbourhood in this city.

Our crews are full-time BaseWorks employees - not subcontractors. Every project is supervised by a licensed general contractor and signed off by a structural engineer of record. When we say the work is done right, there is a paper trail to prove it.

Our Services

Full-Scope Basement
Underpinning Services

As specialized basement underpinning contractors and basement lowering contractors serving Toronto and the GTA, we handle the full range of below-grade structural work - under one roof, with one point of accountability.

Foundation Underpinning
We underpin foundations to increase structural bearing depth, stop active settlement, and create usable headroom. Every underpinning sequence is engineered with a licensed structural engineer's stamp - no guesswork, no skipped steps. We work in a phased sequence that keeps your home structurally safe throughout the entire process.
Basement Lowering
Many basement lowering contractors in Toronto skip the structural analysis and hand you a rough quote over the phone. We don't. Every lowering project begins with an on-site assessment, engineer review, and a written fixed-price quote before a single shovel hits the ground. The result is a legal, inspected, fully livable basement.
Waterproofing
Every underpinning project is the ideal moment to address water infiltration permanently - the walls are already open. We install drainage board, weeping tile, and membrane waterproofing systems as part of the underpinning scope, eliminating the need for a second round of excavation and the extra cost that comes with it.
Walkout Conversions
We create legal walkout access from existing below-grade spaces - adding real resale value and livable square footage to Toronto homes. Every walkout conversion is fully permitted, includes retaining wall design where required, and finishes with inspected concrete stairs and a weather-sealed entrance that satisfies the building department.
Foundation Crack Repair
We injection-repair structural cracks using high-performance epoxy and polyurethane systems that bond, seal, and flex with the foundation through Toronto's freeze-thaw cycles. Our crack repair work restores structural integrity and waterproof continuity without requiring excavation - and comes with documentation of the repair for your property records.
Crawl Space Conversion
Converting a low-clearance crawl space into full basement height is one of the highest-ROI upgrades available to Toronto homeowners. BaseWorks handles the complete scope: excavation, underpinning, waterproofing, concrete floor pour, and final inspection - delivering a finished below-grade space that adds genuine square footage to your home.
Why BaseWorks

What Sets Licensed Underpinning
Contractors Apart

Not every basement underpinning contractor in Toronto operates the same way. Here is what BaseWorks does differently - and why it matters to your home, your permit record, and your investment.

01
Engineer-Stamped Drawings on Every Project
We don't estimate load paths - we calculate them. Every underpinning sequence carries a licensed structural engineer's stamp before a shovel touches the ground. This protects your structure, satisfies building inspectors, and produces documentation that holds real value when you refinance or sell. Many underpinning contractors in Toronto skip this step. We don't.
02
Full Permit Compliance - No Exceptions
We pull permits, pass every inspection, and hand you the closed permit documentation that protects your property value and insurance coverage. Unpermitted basement underpinning can void home insurance, trigger city orders, and kill real estate transactions. We have a 100% permit pass rate because we don't start work until the drawings are inspection-ready.
03
Fixed-Price Contracts - Your Quote Is Your Price
We have never charged a surprise extra since we opened. If we uncover something unexpected during excavation - a buried obstruction, an unmarked utility, a condition worse than the site assessment suggested - we stop, show you exactly what we found, and give you a written change order before any additional work proceeds. You decide. Always.
04
Full-Time Employed Crews - Not Rotating Subcontractors
Every worker on a BaseWorks site is a direct employee - not a day-labourer or revolving subcontractor. Our crews know our standards, have completed our training program, and are accountable to BaseWorks on every site they work. Quality and consistency come from people who show up for every project, not just the ones that fit their schedule.
05
$5M Liability + WSIB Clearance - Verified Before We Start
Basement excavation contractors in Toronto operating without proper insurance put homeowners at serious financial and legal risk. BaseWorks carries $5M general liability insurance and active WSIB clearance certificates. We provide both documents before we break ground - ask for them upfront, and we will produce them immediately. No reputable contractor hesitates at that request.

Our Approach

Engineering-First Basement
Underpinning Contractors

Toronto's housing stock is among the most demanding in Canada for basement underpinning and basement lowering work. Pre-war brick homes in Rosedale and Cabbagetown, postwar concrete-block bungalows in Etobicoke and North York, century semi-detached houses across The Annex and Leslieville - each presents unique structural challenges that generic underpinning sequences are not designed to address.

BaseWorks doesn't apply one-size-fits-all solutions. We assess every foundation individually: soil type, construction era, load distribution, existing drainage conditions, and proximity to neighbouring structures. Our underpinning sequences are designed specifically for each home based on that assessment - not copied from a previous job or estimated from a photo.

Our crews are trained in the specific hazards of below-grade excavation on tight urban Toronto lots. We work within party wall agreements when required, coordinate directly with adjoining property owners on attached homes, and handle all City of Toronto permit applications from initial submission through every required site inspection to final permit closure.

Structural Engineer of Record
A licensed structural engineer reviews, designs, and stamps all underpinning drawings before work begins on every project.
City of Toronto Permit Management
We prepare, submit, and manage all permit applications, required site inspections, and final permit closures on your behalf.
Party Wall Compliance
We manage all party wall agreements and neighbour notification requirements for semi-detached and attached Toronto homes.
Post-Project Documentation Package
You receive closed permits, engineer sign-off letter, 5-year warranty certificate, and project photos at project completion.
