About Our Foundation Repair & Waterproofing Service
A wet basement or a crack in the foundation wall almost always traces back to one thing: water that isn't being managed where it gets in. We're masons first, so we fix the masonry the right way — epoxy injection for structural hairlines, polyurethane for active leaks, and real drainage at the source instead of a coating that buys you one dry season. When a wall has actually moved, that's structural work, and it starts with an on-site assessment — not a number over the phone — so we can tell you straight whether you're looking at stabilization or something a crack repair and better drainage will solve.
What Foundation Problems Actually Mean
Not every crack is an emergency, and not every dry-looking wall is fine. The job on the first visit is reading what the foundation is telling you, because the signs point to very different repairs. A hairline crack running straight down from a corner of a window or a tie-rod hole is usually shrinkage in the original pour — cosmetic until it starts weeping. A crack that's wider at the top or bottom, stepping diagonally through the block, is movement, and that's a different conversation.
- Vertical hairline cracks — common in poured walls, often just shrinkage; the concern is water, not collapse.
- Diagonal or stair-step cracks — point to settlement or soil pressure; these get watched and measured, not just filled.
- Horizontal cracks with bowing — the serious one. Lateral soil pressure is pushing the wall in, and that needs structural attention, not a patch.
- Efflorescence (white chalky residue) — the fingerprint of water passing through masonry and leaving salts behind. Where you see it, water is moving.
- Active seepage or a damp musty smell — water is already getting in; the question is the path, not whether there's a problem.
Crack Repair Done Right
Surface caulk and hydraulic cement smeared over a foundation crack is the repair we get called to undo most often. It bonds to the face of the wall, not into it, so the next freeze-thaw season pops it loose and the crack is back. A real injection fills the crack through its full depth, front to back, and becomes part of the wall.
Which injection depends on what the crack is doing. Epoxy is a structural-grade resin — it's stronger than the concrete around it, so we use it on dry, stable hairline cracks where the goal is to weld the wall back into one piece. Polyurethane is for active leaks: it's flexible and it reacts with water, expanding to chase a wet crack to its source and seal it while staying able to move with the wall. Using the wrong one is why injections fail — epoxy in a wet, moving crack won't bond, and rigid resin in a flexing wall just cracks beside the old repair.
Basement & Foundation Waterproofing — The Honest Version
Nobody waterproofs a basement with a bucket of paint, no matter what the label promises. Water moves under hydrostatic pressure, and the only durable fix is to manage it at the source: keep it away from the wall, and give the water that still arrives a path out that isn't your floor. A coating sprayed over a wet wall hides the stain for a season and traps moisture in the masonry the rest of the time.
There are two real approaches and they solve different problems. Exterior waterproofing — excavating to the footing, cleaning the wall, applying a membrane, and bedding a footing drain in gravel — stops water before it ever touches the foundation. It's the more thorough fix and the bigger job. Interior systems — a French drain channel cut into the slab perimeter, tied to a sump pump — don't stop water from reaching the wall; they intercept it once it's in and pump it out before it hits the floor. Add proper regrading and gutter discharge away from the house, and you've handled the water instead of decorating around it.
When It's Structural — and When It Isn't
Most of what brings people to this page is crack and water work, and most of it is solved without touching the structure. But when a foundation is actively failing — a wall bowing inward, a corner settling unevenly, stair-step cracks that keep growing — that's structural work, and it starts with an on-site assessment rather than a number over the phone. We do handle the structural side. What we won't do is name a fix or a price off a photo, because guessing at structural scope is exactly how homeowners get oversold. We come out, read what the wall is actually doing, and tell you straight whether it needs stabilizing or whether a crack repair and better drainage will settle it down.
If you're seeing the serious signs — a wall leaning in, doors and windows that have started binding, cracks you can fit a coin into — that's the point to get an on-site assessment rather than a patch. We'll measure, tell you whether it's truly structural or just looks alarming, and put the actual scope in writing. Start with a free written estimate and we'll read the foundation with you in person.
Why a Roofing & Masonry Crew Owns This Work
Foundation and waterproofing work is masonry work, and masonry is what we already do every week. The same crew rebuilds chimneys from the roofline down — casting crowns, matching mortar, repointing brick — so brick, block, and mortar aren't a bolt-on service we subcontract; they're the trade. When we tell you a crack needs epoxy and a wall needs drainage, it's coming from people who pack mortar joints for a living. See the same masonry skill on our chimney rebuild and chimney repair work, or the broader masonry, brick & concrete services we offer.
What Drives the Cost
Foundation work spans a wide range because the scopes are genuinely different, so we price off what we find, never a flat menu. The main variables:
- Number and type of cracks — one structural hairline injection is the cheapest item on this list; multiple active leaks is more involved.
- Where the water is coming from — a regrading-and-gutter fix is a fraction of a full exterior excavation and membrane.
- Interior vs. exterior waterproofing — interior drain-and-sump systems sit below the cost of digging out the foundation from outside.
- Access — a walk-out basement is easier to work than a wall buried behind a deck, a driveway, or tight side-yard clearance.
- Structural scope — stabilizing a wall that has actually moved is a different tier entirely from crack and water work, which is exactly why it starts with an on-site assessment rather than a quoted fix.

Foundation Repair & Waterproofing — Common Questions
Are foundation cracks serious?
It depends entirely on the crack. A thin vertical hairline in a poured wall is usually shrinkage from the original cure — the concern there is water getting in, not the wall failing. The ones we take seriously are horizontal cracks with any inward bowing, and diagonal stair-step cracks that keep growing — those point to soil pressure or settlement and need a structural look, not just a fill. We'll measure yours and tell you honestly which category it's in.
Can you stop my basement from leaking?
Yes, but the honest way to say it is that we manage the water rather than wave a wand at it. We find where it's getting in, then fix the actual path — sealing the crack with the right injection, cutting in an interior French drain to a sump, excavating and membraning the exterior wall, or correcting grading and gutter discharge so water never reaches the foundation. A coating sprayed on a wet wall is not waterproofing; it hides the stain and traps the moisture. We do the source work that keeps it dry.
Epoxy or polyurethane injection — what's the difference?
Epoxy is a rigid structural resin that's stronger than the concrete around it, so we use it on dry, stable hairline cracks to weld the wall back into one piece. Polyurethane is flexible and reacts with water — it expands to chase an active leak to its source and seals it while staying able to flex with the wall. Put simply: epoxy for structural hairlines, polyurethane for active water leaks. Using the wrong one is the most common reason an injection fails, so matching the material to the crack is half the job.
Is my foundation structural, or just a repair?
Most foundations we look at need crack and water work, not structural intervention — genuine settlement and movement are the exception, not the rule. The honest answer is that nobody should tell you which one you've got from a photo. If a wall is bowing, the house is settling unevenly, or doors and windows have started binding, we come out, measure what's actually moving, and put the real scope in writing. We do the structural work when it's warranted — but it starts with the assessment, because guessing at it is how people get oversold things they don't need.
Do you offer free foundation estimates?
Yes — every foundation and waterproofing estimate is free and in writing. For crack and water work we can often scope it on the first visit. For anything structural, the on-site assessment is the whole point: we measure the movement, identify the water source, and give you an itemized written estimate for the actual work, not a guess.
