Stair-step cracks in the basement, a bowing wall, or doors that suddenly stick? Our Boston foundation repair specialists inspect the structure, pinpoint why it is moving, and fix it the right way, from foundation crack repair and carbon-fiber reinforcement to underpinning with steel piers, so your home sits solid again.
As certified Boston foundation repair contractors, we begin with a real diagnosis: Whether you are dealing with cracks in the foundation, a bowing basement wall, a settling slab, or a damp crawl space, we assess the structure, explain what is actually happening underground, and lay out every repair option, for both residential and commercial buildings. No surprises.
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.
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.

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.

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.

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.

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.

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.

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.
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.
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.

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.
