Foundation crack repair in Hamilton typically runs $500 to $4,000, depending on the crack's width, length, moisture condition, and whether one or more cracks need attention. That range is wide on paper - but it narrows fast once a project manager actually inspects your crack in person. Here's exactly what the free assessment covers and how we determine which repair method fits your specific situation.
What the Free Assessment Actually Covers
A project manager inspects the crack - measuring width at multiple points, checking for lateral offset, probing for moisture, and reviewing direction and location against known patterns for structural versus cosmetic cracking. That visit tells us whether the crack needs epoxy or polyurethane, and whether it's a straightforward injection job or one that needs an engineering assessment first before anything gets scheduled. A written fixed-price proposal follows within 48 hours, at no charge and no obligation. See our foundation 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 stage.
What Actually Moves the Price
Material & Crack Condition
A dry crack under 3mm needing epoxy is the simplest repair overall. Active moisture pushes the job into polyurethane territory, and through-wall cracks sometimes need exterior injection too, adding to the total.
Number of Cracks & Reinforcement
Multiple cracks in one wall get combined pricing overall. Cracks pointing to lateral movement sometimes need carbon fibre reinforcement, quoted after a structural assessment confirms it.
How We Decide Between Epoxy and Polyurethane
This is the single most important call the assessment makes, and it's not something a homeowner needs to figure out beforehand. Dry, structural cracks get epoxy, which restores the wall's bond strength and cures as strong as or stronger than the original concrete. Wet or actively leaking cracks get polyurethane, which expands to create a watertight seal but doesn't restore structural strength the way epoxy does. Using the wrong material on the wrong crack is a common mistake among less careful contractors - we match the material to the crack's actual condition, every time, based on what the assessment actually finds rather than a default habit.
From Approved Estimate to Sealed Crack
Once you approve the proposal, we schedule the repair - most jobs are completed within a week or two. The appointment itself typically runs 2 to 6 hours per crack: port installation every 8 to 12 inches, surface sealing, injection, and cure. Epoxy reaches full structural strength in 24 to 48 hours; polyurethane seals watertight essentially on contact. If a crack shows signs of active settlement, an engineering assessment happens first, adding roughly a week to the timeline before injection is scheduled. Either way, nothing proceeds without your written approval of the exact scope and price.
Why Book the Assessment Before You Compare Quotes
A Real Mistake This Assessment Actually Catches
Homeowners occasionally come to us after a contractor quoted a repair sight-unseen, or applied the same material to every crack regardless of condition. Epoxy on an actively leaking crack won't bond properly to a wet surface, and polyurethane on a dry structural crack won't restore any strength - both are mismatches that fail faster than they should, sometimes within the same season. The free assessment identifies the right material for your actual crack, not a generic default. For a real example of how this plays out, see our Chedoke case study, or read the full epoxy injection guide if you're still figuring out what your crack needs.
A Real Concrete Example of How Pricing Breaks Down
To make the range concrete: a single dry crack under 3mm and under 24 inches typically lands between $500 and $1,000, with epoxy injection completed same-day in a single appointment. An actively leaking crack of similar length moves into polyurethane territory, usually $800 to $2,000, since the material and approach differ and stopping the leak fully takes priority. Homes with two or more cracks - common in older Hamilton foundations - typically land in the $1,500 to $4,000 range for all of them handled in one mobilization, priced together rather than as separate visits each with its own call-out cost. Cracks needing carbon fibre reinforcement alongside injection run $3,000 to $8,000, and that combined scope is only quoted once a structural assessment confirms it's actually needed for the specific crack in question.
When an Engineer Actually Gets Involved (And When One Doesn't)
Most foundation cracks in Hamilton don't need an engineer at all - a project manager can assess the crack, determine it's a straightforward shrinkage or minor settlement crack, and quote the injection repair directly. An engineer gets brought in specifically for cracks showing patterns that suggest ongoing structural movement: horizontal orientation, measurable lateral offset, or a crack that's grown noticeably since it was first noticed. That assessment typically adds about a week to the timeline but protects against injecting a crack that's still actively moving, which would risk the repair failing again shortly after it's done. The added cost of the engineering step is almost always smaller than the cost of a repair that has to be redone because the underlying movement was never confirmed to have stopped.
Common Questions Homeowners Ask Before Booking
How This Really Differs From a Generic Contractor Quote
Some contractors quote foundation crack repair as a flat rate regardless of the crack's actual condition - the same price whether it's a dry hairline crack or an actively leaking structural one. That approach either overcharges for the simple cases or undercharges for the complex ones, and it skips the diagnostic step that determines which material and approach the crack actually needs. BaseWorks prices after the assessment specifically so the number reflects the real scope of work, not a generic average across every crack we've ever seen on a Hamilton foundation.

Frequently Asked Questions
Yes. A project manager inspects the crack, measures width and location, checks for moisture, and provides a written fixed-price proposal - at no cost and no obligation to book.
Crack width, length, moisture condition, whether multiple cracks are being repaired, and whether carbon fibre reinforcement is needed alongside injection are the main variables. A crack pointing to active settlement is quoted separately once an engineering assessment is complete.
Yes - that's exactly what the assessment determines. Dry, structural cracks get epoxy to restore bond strength. Wet or actively leaking cracks get polyurethane to create a watertight seal. You don't need to know the difference yourself before booking.
No. Most cracks are straightforward injection repairs that a project manager can assess and quote directly. An engineer only gets involved for cracks showing signs of active settlement, like horizontal orientation or lateral offset, where confirming stability matters before repair.
