Foundation cracks are one of the most common — and most misunderstood — problems Pittsburgh homeowners face. Not every crack is a structural emergency, but none of them should be ignored. Even a hairline crack is an entry point for water, and water intrusion is what turns a minor crack into a major repair.
Pittsburgh’s combination of clay soil, freeze-thaw cycles, and hillside lots puts constant stress on foundation walls. Settlement cracks, hydrostatic pressure cracks, and shrinkage cracks are all common in Allegheny County homes — especially those built before 1970. Pittsburgh Dry Basement diagnoses the type of crack, determines the cause, and seals it permanently.
Don’t caulk it and forget it. Hardware store crack fillers are a temporary patch, not a fix. They don’t stop water pressure, they don’t address the cause, and they fail within a season or two. A proper repair seals the crack from the inside out and lasts.
Types of Foundation Cracks
The shape and direction of a crack tells us a lot about what caused it — and how serious it is.
Vertical Cracks
Usually caused by concrete shrinkage as it cures. Very common in poured concrete foundations. Typically not structural, but they do let water in and should be sealed.
Diagonal / Stair-Step Cracks
Common in block and brick foundations. Usually caused by differential settlement — one corner of the foundation settling more than another. Monitor for movement; seal promptly.
Horizontal Cracks
The most serious type. Caused by lateral soil pressure pushing inward against the wall — common on hillside lots. Can indicate the wall is bowing. Requires prompt professional assessment.
Hairline Cracks
Thin surface cracks common in poured concrete as it ages. Usually cosmetic, but should be sealed to prevent water from widening them over time.
How We Repair Foundation Cracks
The right method depends on the crack type, width, and whether it is actively leaking.
Epoxy Injection
Best for dry, structural cracks. High-strength epoxy is injected under pressure to bond the two sides of the crack back together — restoring the wall’s structural integrity. Creates a repair stronger than the original concrete.
Polyurethane Foam Injection
Best for actively leaking cracks. Polyurethane foam expands on contact with water, filling the crack completely and stopping the leak immediately. Flexible enough to handle minor movement without re-cracking.
Carbon Fiber Straps
Used for bowing or horizontal cracks where the wall needs reinforcement. Carbon fiber straps are bonded to the wall surface to halt inward movement and stabilize the structure without excavation.
Exterior Waterproofing + Crack Repair
For severe cases, we combine crack repair with exterior waterproofing — excavating to the footing, sealing the crack from outside, and applying a waterproof membrane to address the root cause.
Signs You Need Foundation Crack Repair
- ● Visible cracks in your foundation wall — vertical, diagonal, or horizontal
- ● Water seeping through a crack after rain or snowmelt
- ● Efflorescence (white mineral deposits) around a crack — a sign of long-term water movement
- ● A crack that has visibly grown wider or longer since you first noticed it
- ● Bowing or bulging in a foundation wall
- ● Doors or windows sticking — can indicate foundation movement
- ● Musty smell or mold near a foundation wall
Our Repair Process
-
1
Free inspectionWe assess the crack type, width, depth, and whether it is actively leaking or shows signs of structural movement.
-
2
Diagnosis & recommendationWe explain exactly what caused the crack, how serious it is, and what repair method is appropriate. No upselling — if a simple epoxy injection is all you need, that is what we recommend.
-
3
Surface preparationThe crack is cleaned, loose material is removed, and injection ports are installed at intervals along the crack.
-
4
Injection & sealingEpoxy or polyurethane foam is injected under low pressure until the crack is fully saturated. The ports are capped and the surface is finished.
-
5
Final inspectionWe verify the repair is complete and walk you through what was done. Most crack repairs are finished in a few hours.

Frequently Asked Questions
How much does foundation crack repair cost in Pittsburgh?
Simple epoxy or polyurethane injection repairs typically run $400–$800 per crack depending on length and severity. More complex repairs involving carbon fiber straps or exterior excavation cost more. We provide a free estimate so you know exactly what you are looking at before any work begins.
Are foundation cracks normal in Pittsburgh homes?
Very common, yes — especially in older homes. Pittsburgh’s freeze-thaw cycles, clay soil, and hillside terrain all put stress on foundations. Hairline cracks from concrete shrinkage are nearly universal. That does not mean they should be ignored, but most are repairable without major structural work.
Can I repair a foundation crack myself?
Hardware store crack fillers can temporarily mask a crack, but they do not stop water pressure and they do not address what caused the crack. Professional injection repair fills the full depth of the crack and creates a lasting seal. DIY patches typically fail within one to two freeze-thaw cycles.
How do I know if a crack is structural?
Horizontal cracks and cracks showing displacement (one side higher than the other) are the most serious and warrant immediate inspection. Vertical and diagonal cracks are usually non-structural but still need to be sealed. When in doubt, get a professional assessment — it is free.
Will repairing cracks keep my basement dry?
Crack repair eliminates water entry through that specific crack. If you have broader moisture issues — hydrostatic pressure, poor drainage, or multiple entry points — we may recommend combining crack repair with a drainage solution or waterproofing system for complete protection.
