Basement crack repair in Hamilton typically runs $500 to $3,500, depending on the crack's width, length, moisture condition, and whether more than one crack needs attention. That range is wide on paper - but it narrows fast once a project manager actually looks at your wall. Here's exactly what the free assessment covers, and why booking it now, before winter freeze-thaw sets in, is worth doing rather than waiting until the crack has had a full season to get worse.
What the Free Assessment Actually Covers
A project manager inspects the crack itself - measuring width, checking for lateral offset, and looking for moisture or efflorescence - along with the surrounding wall for any signs of broader movement. That visit tells us whether the crack is a straightforward injection job or one that needs a structural assessment first, and which repair method actually fits. A written fixed-price proposal follows within 48 hours, at no charge and no obligation. See our basement crack repair service page for the full method and pricing breakdown this estimate is based on.
Fixed-price means fixed. No ranges in your final contract, and nothing new on the invoice once it's signed - only pre-approved change orders if the crack turns out to run deeper than what was originally visible at the assessment.
What Actually Moves the Price
Crack Width & Moisture
A dry hairline crack under 2mm is the simplest and least expensive repair. Active moisture or leaking pushes the job into polyurethane foam injection territory, which costs more than a dry epoxy repair overall.
Number of Cracks & Structural Concern
Multiple cracks handled in one visit get combined pricing. Horizontal or offset cracks needing a structural assessment are quoted separately once that inspection confirms what's actually needed for the wall.
Why Fall Is the Right Time to Book
Hamilton's freeze-thaw cycles hit multiple times most winters, forcing water into any existing crack and widening it a little more with every freeze. A crack that's a $600 repair in October can become a $2,000 repair by March if it's left through a full winter of expansion cycles. Booking the assessment now, before the first hard freeze, is the single cheapest time on the calendar to get ahead of it.
From Approved Estimate to Sealed Crack
Once you approve the proposal, we schedule the repair - most jobs are completed within a week or two of approval, well within the same season and often faster during quieter scheduling windows. The appointment itself typically runs 2 to 5 hours: port installation, surface sealing, low-pressure injection, and cleanup, with the material fully cured in 24 to 48 hours. No excavation, no exterior disruption, and nothing to your landscaping - the entire repair happens from inside the basement, start to finish.
Why Book the Assessment Before You Compare Quotes
A Mistake This Assessment Catches
Homeowners occasionally come to us after trying a DIY crack sealant kit that stopped visible water but didn't address what was pushing it through in the first place. The crack usually reopens somewhere nearby within a season or two, and by then a bit more of the wall has been affected than the original spot. The free assessment identifies whether a crack needs a permanent injection repair or is genuinely minor enough to monitor - either way, you're working from an honest read rather than a guess. For a real example of how this plays out, see our Kirkendall case study, or read the full basement wall crack guide if you're still figuring out what your crack means.
The same applies to a quote that skips the assessment entirely. A price given over the phone, based only on a homeowner's description of a crack, is a guess dressed up as a number - and it tends to move once someone actually sees the wall in person. We'd rather send a project manager out first and put a real, honest number in writing than quote blind and adjust later, which is a common source of frustration homeowners consistently report with other contractors in this space.
How This Differs From a Generic Waterproofing Quote
Some waterproofing companies fold crack repair into a broader exterior waterproofing sales pitch, quoting a full exterior excavation and membrane system for a problem that a $600 interior injection would have solved just as effectively and far more quickly. Basement crack repair on its own, when the crack itself is the actual problem rather than a symptom of a much larger waterproofing failure, almost never requires exterior excavation. The free assessment is what tells you which situation you're actually in - a contained crack repair, or a larger waterproofing issue the crack happens to be one visible symptom of.
A Real Example of How Pricing Breaks Down
To make the range concrete: a single dry, hairline crack under 2mm and under 24 inches long typically lands between $500 and $900, with epoxy injection completed in under an hour of actual working time within a same-day appointment. A wet or actively leaking crack of similar length moves into polyurethane foam territory, usually $800 to $2,000, since the material and technique differ and the leak needs to be fully stopped, not just cosmetically sealed. Homes with two or three separate cracks - common in older houses that have settled unevenly over decades - typically land in the $1,500 to $3,500 range for all of them handled in one visit, priced together rather than as separate call-outs each carrying its own mobilization cost.
What If the Assessment Finds a Structural Issue?
Sometimes what looks like a simple crack turns out to need more than injection - a horizontal crack with real lateral offset, for example, might call for carbon fibre reinforcement or, in more advanced cases, wall anchors. If that's what your assessment finds, we'll explain exactly why, walk through the options, and give you a separate fixed-price quote for that scope rather than trying to fold a bigger structural repair into a basic crack injection price. You're never left guessing which category your crack falls into once the assessment is done, and the decision on how to proceed is always yours to make.

Frequently Asked Questions
Yes. A project manager inspects the crack, measures width and any offset, checks for moisture, and provides a written fixed-price proposal - at no cost and no obligation to book.
Crack width, length, moisture condition, and whether one or multiple cracks are being repaired are the main variables. A horizontal or offset crack needing a structural assessment is quoted separately once that inspection is complete.
Freeze-thaw cycles through winter force water into existing cracks and widen them each time it freezes. Sealing a crack before the first hard freeze prevents a full winter of that expansion cycle from turning a minor crack into a bigger repair by spring.
No. Determining whether a crack is cosmetic or structural is exactly what the assessment covers. Many homeowners call specifically because they're unsure, and that's the first thing we confirm on-site.
