Our Story

Built for Hamilton
Basements.

BaseWorks started because a group of tradespeople got tired of watching Hamilton homeowners pay full price for half-finished basement work. Too many contractors in this city were skipping engineer-stamped drawings, pulling incomplete permits, and handing over surprise invoices partway through a job. Homeowners had no real way to tell a qualified crew apart from someone working out of a van with a borrowed excavator.

So we built something different: a basement underpinning company where engineering comes first, permit compliance is never optional, and the price on the contract doesn't move once it's signed. That's genuinely the foundation - pun fully intended - that BaseWorks was built on.

Today, we're among the most experienced basement underpinning contractors working in Hamilton. We've lowered floors in century-old semis across Westdale, reinforced crumbling foundations in postwar bungalows in Waterdown, waterproofed century homes in Binbrook, and converted crawl spaces throughout Ancaster - every soil condition, every construction era, every neighbourhood the city has to offer.

Every person on a BaseWorks crew is a full-time employee, not a subcontractor pulled in for the job. 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's an actual paper trail behind that claim.

Our Services

Full-Scope Basement
Underpinning Services

As basement underpinning and basement lowering contractors serving Hamilton, we handle the full range of below-grade structural work under one roof, with a single point of accountability for the entire project.

Foundation Underpinning
Underpinning extends bearing depth, stops active settlement, and creates real usable headroom. Every sequence is engineered with a licensed structural engineer's stamp - no guesswork, no skipped steps - and phased in a way that keeps the home structurally safe throughout.
Basement Lowering
Too many contractors will skip the structural analysis entirely and hand you a rough number over the phone. We won't. Every lowering project starts with an on-site assessment, an engineer review, and a written fixed-price quote before a single shovel touches the ground - the result is a basement that's legal, inspected, and fully livable.
Waterproofing
An underpinning project is the ideal moment to solve water infiltration for good - the walls are already open, so the opportunity's already there. We install drainage board, weeping tile, and membrane waterproofing as part of the same scope, avoiding a second round of excavation and the extra cost that comes with it.
Walkout Conversions
We build legal walkout access from existing below-grade spaces, adding real resale value and genuinely livable square footage. Every conversion is fully permitted, includes retaining wall design where the site calls for it, and finishes with inspected concrete stairs and a weather-sealed entrance that clears the building department.
Foundation Crack Repair
Structural cracks get injection-repaired with high-performance epoxy and polyurethane systems built to bond, seal, and flex with the foundation through Hamilton's freeze-thaw cycles. The repair restores both structural integrity and waterproof continuity without any excavation, and you get documentation of the work for your property records.
Crawl Space Conversion
Converting a low-clearance crawl space into full basement height is genuinely one of the highest-ROI upgrades available to a Hamilton homeowner. We handle the full scope - excavation, underpinning, waterproofing, concrete floor pour, and final inspection - delivering a finished below-grade space that adds real square footage to the home.
Why BaseWorks

What Sets Licensed Underpinning
Contractors Apart

Not every basement underpinning contractor in Hamilton operates the same way. Here's what we do differently, and why it actually matters to your home, your permit record, and your investment.

01
Engineer-Stamped Drawings on Every Project
Load paths get calculated, not estimated. Every underpinning sequence carries a licensed structural engineer's stamp before a shovel touches the ground, which protects your structure, satisfies building inspectors, and produces documentation that holds real value at refinance or resale. A lot of underpinning contractors in Hamilton skip this step entirely. We never do.
02
Full Permit Compliance - No Exceptions
Permits get pulled, every inspection gets passed, and you walk away with closed permit documentation that protects your property value and insurance coverage. Unpermitted underpinning can void home insurance, trigger a city order, and kill a real estate transaction outright. Our permit pass rate sits at 100% because we simply don't start work until the drawings are inspection-ready.
03
Fixed-Price Contracts - Your Quote Is Your Price
We've never charged a surprise extra since opening our doors. If something unexpected turns up during excavation - a buried obstruction, an unmarked utility, a condition worse than the assessment suggested - we stop, show you exactly what we found, and give you a written change order before another shovel of dirt moves. It's always your call.
04
Full-Time Employed Crews - Not Rotating Subcontractors
Everyone on a BaseWorks site is a direct employee, not a day-labourer or a rotating subcontractor. Our crews know our standards, have gone through our training program, and answer to BaseWorks on every job. Consistency comes from people who show up for every project, not just the ones that happen to fit their schedule that week.
05
$5M Liability + WSIB Clearance - Verified Before We Start
A basement excavation contractor operating without proper insurance puts the homeowner at serious financial and legal risk. We carry $5M in general liability insurance and hold active WSIB clearance certificates, provided before we break ground on anything. Ask for them upfront and we'll hand them over immediately - no reputable contractor hesitates at that request.

Our Approach

Engineering-First Basement
Underpinning Contractors

Hamilton's housing stock is genuinely one of the more demanding in Canada for basement underpinning and lowering work. Pre-war brick homes in Binbrook and Dundas, postwar concrete-block bungalows in Ancaster and Waterdown, century semi-detached houses across Stoney Creek and Westdale - each brings its own structural challenges that a generic, copy-paste underpinning sequence isn't built to handle.

One-size-fits-all isn't how we approach this. Every foundation gets assessed individually: soil type, construction era, load distribution, existing drainage, and proximity to neighbouring structures. The underpinning sequence gets designed specifically for that home, based on that assessment - never copied from a previous job or estimated from a photo.

Our crews are specifically trained in the hazards of below-grade excavation on Hamilton's tight urban lots. We work within party wall agreements when required, coordinate directly with adjoining property owners on attached homes, and manage every City of Hamilton permit application from initial submission through every required inspection to final closure.

Structural Engineer of Record
A licensed structural engineer reviews, designs, and stamps every underpinning drawing before work begins - on every project, without exception.
City of Hamilton Permit Management
Every permit application, required inspection, and final permit closure gets prepared, submitted, and managed on your behalf, start to finish.
Party Wall Compliance
All party wall agreements and neighbour notification requirements are managed directly by us for semi-detached and attached Hamilton homes.
Post-Project Documentation Package
At project completion, you receive closed permits, the engineer's sign-off letter, a 5-year warranty certificate, and full project photos.
