Foundation Repair Services in Boston
From a hairline crack in the basement wall to a foundation settling on one side, here’s how we diagnose the movement, stabilize the structure, and restore your foundation.
Foundation Crack Repair
Hairline, vertical, and stair-step cracks in the foundation rarely fix themselves. We seal and reinforce them with polyurethane or epoxy crack injection, and where the wall is under pressure, carbon-fiber reinforcement, stopping water intrusion and keeping the crack from spreading.
Bowing & Cracked Wall Repair
When a basement wall bows inward or shows horizontal cracks, soil and water pressure is winning. We straighten and brace bowing walls with carbon-fiber straps or steel I-beams and handle wall crack repair before it threatens the rest of the structure.
Foam Concrete Leveling
Sunken walkways, patios, driveways, and garage slabs get lifted back into place with polyurethane foam leveling, a fast, low-mess alternative to old-school mudjacking that cures in minutes so you can use the surface the same day.
Crawl Space Repair & Encapsulation
Damp, sagging crawl spaces invite mold, pests, and bouncy floors above. We repair failing supports, install vapor barriers, and fully encapsulate the crawl space, often paired with a sump pump, to keep water out and the structure dry.
Concrete Slab Leveling
A slab foundation that has settled or heaved leaves uneven floors, cracked tile, and tripping hazards. We level concrete slabs with polyjacking and stabilize the soil beneath, so the slab stays put instead of sinking again.
Underpinning & Pier Systems
When a foundation is actively settling, underpinning transfers the load to stable soil far below. As experienced underpinning contractors, we install push piers and helical piers to lift and permanently stabilize homes and commercial buildings.
Full-Service Foundation Repair & Stabilization
One call covers the whole job, from foundation inspection and crack repair to wall bracing, slab and foam leveling, crawl space repair, and underpinning, for residential and commercial properties across Boston.

Foundation Inspection and Repair Costs in Boston
No two foundation problems are identical, which is why guessing at a price helps nobody. The honest answer to “what is the basement foundation repair cost” depends on the cause and the method: a single crack injection is a modest fix, while full underpinning with piers is a larger structural job. We start with a foundation inspection so the estimate reflects the actual repair, not a worst-case number. Boston’s clay-heavy soil, freeze-thaw winters, and older housing stock all put steady pressure on foundations, so catching movement early almost always costs less.
Common signs of foundation problems
Watch for cracks in the foundation or basement walls, especially horizontal or stair-step cracks, doors and windows that suddenly stick, sloping or bouncy floors, gaps where walls meet the ceiling, and water seeping into the basement or crawl space. Any one of these can signal settlement, soil pressure, or a bowing wall, and they tend to worsen through Boston’s wet springs and frozen winters. Documenting when a crack appears and whether it widens helps us pinpoint the cause faster.
Repair methods, from crack injection to underpinning
The right method depends entirely on the diagnosis. Minor cracks get polyurethane or epoxy crack injection; bowing walls are braced with carbon-fiber straps or steel beams; sunken slabs, patios, and walkways are raised with foam leveling; and a genuinely settling foundation is stabilized by underpinning contractors using push piers or helical piers. Damp crawl spaces are repaired and encapsulated, often with a sump pump, to protect the structure for the long term. We tell you which method applies to your home or commercial building, and exactly why.
Frequently Asked Questions
Answers to the most common questions about foundation repair in Boston, covering cost, cracks, underpinning, leveling, and what to do when something fails fast.
Still have questions? Contact us
How much does foundation repair cost in Boston? +
There is no flat rate. Foundation repair cost depends on the cause and the fix: a crack injection is a small job, while underpinning a settling foundation with piers is a larger one. We inspect the foundation first, then give you a clear, upfront price before any work begins.
Are the cracks in my foundation serious? +
It depends on the type. Thin vertical cracks are often minor, but horizontal or stair-step cracks, or any crack that keeps widening, can point to soil pressure or settlement and should be inspected promptly. After a foundation inspection we will tell you honestly whether it is cosmetic or structural.
What is underpinning, and do I need it? +
Underpinning stabilizes a settling foundation by transferring its weight to stable soil deep below, using push piers or helical piers. Not every home needs it. As underpinning contractors, we recommend it only when a foundation is actively settling, and lighter fixes like crack injection or wall bracing when those will do.
Can you fix a bowing basement wall? +
Yes. Bowing or cracked walls are usually caused by soil and water pressure against the foundation. Depending on severity we reinforce them with carbon-fiber straps or steel I-beams, and in serious cases relieve the outside pressure, restoring the wall’s strength without a full rebuild.
What is foam concrete leveling? +
It is a fast way to lift sunken concrete, driveways, patios, walkways, and slabs, by injecting expanding polyurethane foam underneath. It is cleaner and cures far quicker than traditional mudjacking, and you can usually walk or park on the surface the same day.
Do you offer emergency foundation repair? +
Yes. We provide 24/7 emergency response for sudden wall movement, rapidly widening cracks, and water flooding a basement or crawl space. Call us and we will get a crew out to assess and stabilize the situation as quickly as possible.

★★★★★
We had stair-step cracks running up the basement wall and one company immediately pushed a full underpinning quote. These folks inspected it, explained it was soil pressure, and fixed it with carbon-fiber straps for a fraction of the price. The cracks have not moved since.

★★★★★
Our garage slab had sunk a couple of inches and the floor inside was sloping. They foam-leveled the slab and had it usable the same afternoon, clean, fast, and exactly what they quoted. No pressure to do more work than we actually needed.
