Crawl space excavation in Hamilton typically runs $65,000 to $120,000 - more than standard basement lowering, because the project involves greater depth, more soil removal, and often trickier access. Here's what the free assessment covers, what actually drives the price, and how to book yours.
What the Free Assessment Actually Covers
Every access point into the existing crawl space gets inspected - current clearance, foundation type and condition, soil and moisture, the beam and post layout, and where utilities currently run. We measure the full footprint and document the framing overhead before writing up a fixed-price proposal that covers both the excavation and the waterproofing that comes with it.
Fixed-price means fixed. Permits, engineering, soil removal, underpinning, waterproofing, slab - it's all one number on your proposal, and that number doesn't move once you've signed.
What Actually Moves the Price
Footprint & Starting Clearance
More crawl space area means more soil, more underpinning perimeter, and more slab. Starting from 30 inches of clearance means digging further than starting from 48 inches to hit the same 8-foot target.
Access & Utility Relocation
Tight access adds labour hours for moving soil and equipment through, and any plumbing or electrical sitting at the old crawl space elevation has to be repositioned to match the new floor.
From Approved Estimate to Finished Basement
Once you approve the proposal, our structural engineer of record designs the underpinning sequence, temporary shoring, beam and post modifications, and the final floor structure - all stamped and submitted with the Hamilton permit application, typically 4 to 8 weeks of processing. Physical work follows the full sequence: access creation, perimeter underpinning, central excavation, then waterproofing and the final slab.

Frequently Asked Questions
Yes - there is no cost and no obligation. We inspect your access points, framing, soil, and current clearance, then provide a written fixed-price proposal covering both excavation and waterproofing.
Crawl space excavation involves greater depth, more soil to remove, and often trickier access and utility relocation than standard basement lowering - which is why most Hamilton jobs land between $65,000 and $120,000 rather than the lower basement lowering range.
Structural engineering and the City of Hamilton permit package typically take 4 to 8 weeks after you approve the proposal. That timeline, along with the full construction sequence, is spelled out in your written estimate.
