Here's what to look for.
Catch any of these early and you'll save thousands. Ignore them and the problem compounds, fast.
Why this is happening.
Understanding the cause is half the repair. Symptoms come back when root causes aren't addressed.
Temperature Fluctuations
Expanding and contracting soil caused by freeze-thaw cycles stresses your foundation.
Foundation Settlement
Uneven settling due to soil conditions creates stress and cracks.
Water Damage
Poor drainage or excessive moisture weakens the foundation, leading to cracks.
Soil Movement
Expansive soils shift, causing your foundation to move and crack over time.
How we fix it, right.
We match the method to the damage, not the other way around. No one-size-fits-all.
Epoxy & Polyurethane Injection
Ideal for sealing smaller cracks and preventing water intrusion, low-pressure resin fills cracks to their full depth.
Carbon Fiber Reinforcement
Reinforcing larger cracks with carbon fiber strips for added structural support.
Foundation Piering
Elevating and stabilizing foundations that have experienced significant settlement or movement.
Waterproofing Solutions
Protecting your foundation from future water damage with improved drainage and waterproof coatings.
Manufacturer-grade. Brand-named.
We don't use hardware-store filler. Every product below is sourced from manufacturers that don't sell to DIYers, and we're trained directly with most of them.
Expandable polyurethane resin
For active leaking cracks. Reacts with moisture, expands to fill the full wall depth, flexes with seasonal movement so it doesn't pop out.
Structural epoxy resin
For dry, non-moving structural cracks. Bonds the concrete back into one monolithic piece — full structural integrity restored.
Carbon fiber reinforcement straps
Bonded across the crack and anchored top and bottom. Distributes load across the full wall, prevents the crack from re-opening, and triggers the lifetime transferable warranty when applied full-wall.
Stabl Wall structural strengthening system
Engineered system for severely bowing or buckling foundation walls. Anchors into the footing and the sill plate; we're certified installers since 2018.
Hydraulic cement (water plug)
For immediate water control during repair so injection can bond properly. Not the long-term seal — just buys us a dry working surface.
From your call to the warranty document.
Honest day-by-day expectations. No mystery scheduling, no "we'll be there next week" that turns into next month.
Inspection
Free on-site visit. Raf reads the crack pattern, documents moisture readings, and explains what's actually causing it. You leave with a written, fixed-price quote.
Materials staging
We pre-stage the right resin (polyurethane vs. structural epoxy), surface prep tools, and any reinforcement (carbon fiber straps, Stabl Wall hardware) for your specific repair.
Repair
Surface prep, port placement, low-pressure injection at full wall depth, and any reinforcement applied. Single-crack jobs typically finish in one day; multi-crack or carbon-fiber reinforced repairs run 1–3 days.
Walkthrough & warranty doc
Raf returns, walks you through what was done, and hands you the signed warranty document plus before/during/after photos for your records (useful at closing if you sell).
Real pricing for foundation repair in CT & NY.
Single active leaking vertical crack with full-depth polyurethane injection. Most common quote we write in CT and NY.
Three factors do the heavy lifting.
Severity
Hairline shrinkage cracks cost less than wider settlement or structural cracks. Width, depth, and pattern all change the scope.
Active water vs. dry
Leaking cracks need expandable polyurethane and may need drainage correction. Dry cracks can use slower-curing structural epoxy. Water doubles the typical bill.
Cosmetic vs. structural
A single non-moving hairline gets a workmanship warranty and a lower price. Structural cracks treated with full-wall carbon fiber qualify for the lifetime transferable warranty and reflect the long-term cost.

From a single-family hairline crack to municipal-scale structural work.
Residential
Single-family homes, townhouses, and multi-family, minor hairline cracks to significant structural damage, thoroughly addressed.
Commercial
Offices, retail, warehouses. Efficient, long-lasting repairs that minimize downtime and prevent regulatory violations.
Healthcare
Hospitals and clinics, low-dust methods that preserve sterile environments and patient safety.
Municipal
Schools, courthouses, fire stations, code-compliant repairs that minimize disruption to essential services.
Historical Buildings
Specialized techniques that combine traditional craftsmanship with modern safety, preserving historical significance.

Tap the crack types below to understand what's happening with yours. Then send us a photo, we'll confirm and quote.
Inner Corner Crack
Crack at the inside corner where two foundation walls meet. The most critical pattern, almost always structural.
We don't patch. We fix permanently.
Every structural repair restores the section with a stronger, more sustainable material than what originally failed. If a crack is identified as structural, the only honest fix is to rebuild that section with a superior material, since the original already failed once. That's not an upsell, it's the rule that keeps a lifetime warranty real.
Foundation Repair, answered.
The questions homeowners actually ask us when foundation repair comes up at the inspection.
How much does foundation crack repair cost in CT and NY?
Typical single active leaking crack ranges $1,500–$2,500 with full-depth polyurethane injection — that's the most common quote we write across Fairfield County and Westchester. Full residential range goes from ~$500 (cosmetic seal) to $5,000+ (structural crack with full-wall carbon fiber reinforcement). The exact number depends on crack severity, whether water is actively coming through, and whether the wall needs structural reinforcement.
How long does the repair take?
Most single-crack injections finish in one day on site. Multi-crack repairs or jobs that include carbon fiber reinforcement typically run 1–3 days. From your initial call, we'll be on-site for a free inspection within 48 hours, and we can usually schedule the repair the following week.
Do I need to leave my home during the repair?
No. Foundation crack repair happens in the basement and produces minimal noise and dust. We use containment sheeting to protect finished spaces and clean up at the end of each day. You can stay in the house, work from home, or come and go as normal.
Will I see the repaired crack afterward?
There will be a visible line where the crack was, similar to a hairline shadow on the concrete. The structural repair is permanent; the cosmetic finish is up to you. We can grind, parge, or paint-match the surface for an additional fee if a clean cosmetic finish matters (most basements stay raw concrete and don't need it).
What if the crack is actively leaking water?
Active leaks need expandable polyurethane (not epoxy) — the resin reacts with moisture and expands to fill the full wall depth. We also check the exterior drainage pattern: if downspouts, grading, or yard drainage are dumping water against the foundation, the crack will keep getting hit. We'll flag and fix the source, not just the symptom.
Is the crack structural or just cosmetic?
Three patterns are almost always structural and need carbon fiber reinforcement: horizontal cracks lower than 1 ft from the floor, inner-corner cracks, and any crack widening year over year. Hairline shrinkage cracks and short stable verticals are typically cosmetic. We classify yours during the on-site inspection — and we don't upsell structural treatment when it isn't warranted.
How soon can you come out?
Free on-site inspections are usually scheduled within 48 hours of your call across Fairfield County, CT and Westchester County, NY. For active flooding or imminent structural concerns we offer same-day or next-day visits — call the main line and tell us it's urgent.
What does the lifetime warranty actually cover?
Lifetime transferable coverage applies to one specific repair geometry: a structural crack repaired with full-wall carbon fiber reinforcement plus deep epoxy injection. If that repair ever reopens or leaks at the repaired location, we come back and re-do it at no charge — and the coverage transfers to the next homeowner if you sell. Other repairs (standalone injection, drainage, masonry) come with workmanship warranties of 1–5 years, also documented in writing. See the full breakdown on the warranty page.
