Foundation repair in Hamilton ranges from $500 for a single crack injection to $90,000 for full perimeter underpinning, and the only way to know which end of that range applies to you is a real, on-site assessment. Here's exactly what the free assessment covers, and why it matters more on a foundation project than almost any other home repair.
What the Free Assessment Actually Covers
A project manager - or a structural engineer, if what you're describing suggests active movement - inspects your foundation for cracks, wall bowing or leaning, and checks exterior grading and drainage for contributing causes. That visit determines which of the four repair categories actually applies: crack injection, wall stabilization, partial underpinning, or full underpinning. A written fixed-price proposal follows within 48 hours, at no charge and no obligation. See our foundation 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 assessment findings change once work is underway.
How the Assessment Matches You to the Right Method
Simple Cases
An isolated, dry or leaking crack with no offset typically gets a straightforward injection quote directly from the project manager - no engineer needed.
Structural Cases
Bowing walls, settlement, or cracks with lateral offset bring in a structural engineer to confirm the cause and extent before any reinforcement or underpinning gets specified.
From Approved Estimate to Finished Repair
Once you approve the proposal, timelines vary by method. Crack injection can often be scheduled within days. Wall stabilization with carbon fibre typically completes in 2 to 5 days once scheduled. Underpinning of any scale requires engineer-stamped drawings and a City of Hamilton permit first, typically running 4 to 8 weeks before physical work begins. Whatever your assessment finds, you get a realistic timeline in writing before committing to anything.

A Real Example of How Pricing Breaks Down
To make the range concrete: a single dry crack under 3mm typically runs $500 to $1,000 to inject, done same-day. A bowing wall needing carbon fibre reinforcement, like our Strathcona case study, usually lands between $3,000 and $8,000 depending on wall length and how many reinforcement points are needed. Settlement localized to one or two sides of the foundation typically runs $8,000 to $20,000 for partial underpinning. Active settlement affecting the full perimeter moves into full underpinning territory, $45,000 to $90,000. Most Hamilton foundation calls land in the first two categories - full underpinning is reserved for genuinely severe, widespread cases.
A Mistake This Assessment Catches
Homeowners occasionally come to us after a contractor recommended underpinning for a problem that turned out to be a contained, stabilized wall bow needing only carbon fibre reinforcement - a massive difference in scope and price for what should have been a much simpler fix. The opposite happens too: a "quick crack repair" quoted without checking for lateral offset or wall movement, missing a genuine structural issue entirely. The free assessment matches the repair to what your foundation is actually doing, not a default recommendation in either direction. Our full cost guide breaks down every method and warning sign in detail.

Questions Homeowners Ask Before Booking
What If the Assessment Finds a Bigger Problem?
Sometimes what a homeowner describes as "one small crack" turns out, once inspected, to be part of a wider settlement pattern affecting more of the foundation than expected. When that happens, we explain exactly what we found and why, walk through the options at each price point, and give you a fixed-price quote for whatever scope actually addresses the problem - not the smallest fix that technically applies, and not an inflated worst-case number either. You're never left guessing which category your foundation falls into once the assessment is complete, and the decision on how to proceed, including whether to get a second opinion first, is always yours.
How This Differs From a Generic Contractor Quote
Some contractors quote foundation work as a flat rate per linear foot or per visible crack, regardless of what's actually driving the problem. That approach either overcharges for a simple, contained issue or undersells something that genuinely needs engineering and reinforcement. BaseWorks prices after the assessment specifically so the number reflects your foundation's real condition - not a generic average across every foundation we've ever quoted in Hamilton.
The same gap shows up in what's included. A quote that doesn't specify whether engineering, permits, or warranty terms are part of the number isn't actually comparable to one that spells all of that out - even when the headline price looks similar. The written proposal that follows your assessment lists exactly what's covered, so you're comparing complete quotes rather than guessing at what a cheaper-looking one might be leaving out.
Why Some Foundation Issues Warrant a Faster Timeline
Not every foundation problem needs to be addressed on an emergency basis, but a few situations genuinely do move faster than others. Active water intrusion at a crack, a wall that's visibly progressing (confirmed by comparing to an old photo or a fresh pencil mark), or door and window function that's changed noticeably in recent months are all signs that whatever's happening hasn't stabilized yet. In those cases, we prioritize scheduling the assessment sooner rather than working through a standard queue, since confirming whether movement is ongoing changes what the right response actually is. Most calls don't fall into this urgent category - but if yours does, say so when you book, and we'll get someone out faster rather than defaulting to the standard scheduling window.
Frequently Asked Questions
Yes. A project manager or structural engineer inspects your foundation, measures any cracks or wall movement, and checks grading and drainage. That visit determines which of the four repair categories applies, and a written fixed-price proposal follows within 48 hours.
Yes - that's the central purpose of the assessment. We determine whether your foundation needs crack injection, wall stabilization, partial underpinning, or full underpinning based on what's actually happening structurally, not a default recommendation.
The repair category itself is the biggest factor - crack injection, wall stabilization, partial underpinning, and full underpinning are four very different scopes and price points. Within each category, length or area affected, access, and whether an engineer needs to be involved all move the number.
No. Straightforward crack injection is typically assessed and quoted by a project manager directly. An engineer gets involved for anything showing signs of structural movement - bowing walls, settlement, or cracks with lateral offset - where confirming the cause and extent matters before any repair method gets specified.
