foundation problems don't fix themselves They get worse!

Your foundation does one job: support the entire weight of your home while resisting the constant pressure of the soil surrounding it.

When something disrupts that balance — shifting soil, hydrostatic water pressure, or freeze-thaw cycles — the foundation begins to move.

In New England, that pressure is relentless. Frost heave in winter, saturated soil in spring, and drought-driven soil contraction in summer put your foundation through an annual cycle of stress that compounds over time. What starts as a hairline crack or a slightly bowing wall can escalate into a serious structural failure if left unaddressed.

The good news: Keller has been solving exactly these problems for over 53 years. Our structural repair systems are designed to stop active movement, restore stability, and give you a permanent solution — not a temporary patch.

WARNING SIGNS OF A
DISTRESSED FOUNDATION

Most water related property problems get worse — not better — over time. Here are some of the warning signs you shouldn’t ignore.

Horizontal Cracks In Foundation Walls

The most serious type of foundation crack — caused by soil pressure pushing inward. These indicate the wall is actively bowing and require immediate attention.

Bowing or Leaning Walls

When a wall visibly curves inward, the structural integrity of your foundation is compromised. The further it moves, the more expensive the repair.

Uneven or Settling Floors

Floors that slope, dip, or feel springy are often the first sign that soil beneath your foundation has shifted or compressed.

Sticking Doors & Windows

When your foundation shifts, your entire home moves with it — causing door frames and window openings to rack out of square.

Don't wait until small problems become expensive disasters. A free inspection costs you nothing.

Piering Systems
Stop the Sinking

If your foundation is settling or your floors are no longer level, Keller's piering systems transfer the load to stable ground — so the movement stops for good.

When a foundation has settled or is sinking due to unstable or shifting soil, the only lasting solution is to transfer the load of your home to stable ground far below the surface. Keller installs helical pier and push pier systems that bypass the problem soil entirely, driving steel into bedrock or load-bearing strata to permanently stabilize your foundation — and in many cases, restore it to its original position.

Unlike surface-level repairs that mask the symptom, piering corrects the root cause. Once installed, the system becomes a permanent part of your foundation’s structural support — backed by Keller’s lifetime transferable warranty.

Steel Beam Systems Stop The Bowing

If your foundation walls are bowing or leaning inward, Keller's wall support systems stop the movement now — and can gradually restore your wall toward its original position over time.

A bowing foundation wall is one of the most urgent problems a homeowner can face. As soil pressure pushes inward — accelerated by water saturation and freeze-thaw cycles — your wall is actively moving. Every inch it bows makes repair more expensive and more complex. Keller’s steel beam and wall anchor systems are engineered to halt that movement immediately and, over time, can actually restore the wall toward its original position.

The right system depends on the severity of the bowing, the type of foundation material, and the available space on your property. Keller evaluates each situation individually and recommends the method that delivers the most durable result for your specific conditions.

Immediately halts active inward movement — no more waiting and watching it get worse
Steel I-beams can be tightened over time to gradually restore the wall toward plumb

Concrete SLAB
replacement

We also offer full concrete slab replacements of existing slabs that are extremely thin, termed “rat slab” that are no longer structurally sound.

Keller Waterproofing & Foundation Specialist knows the most reliable methods to repair concrete so they can be repaired or replaced. We’ve fixed hundreds of thousands of cracked slabs since 1972.

Lally Columns
The Supports Your Home Stands On.

If the columns holding up your main beam are rusted, undersized, or settling, every floor above them is affected — Keller inspects, repairs, reinforces, and replaces lally columns as part of every comprehensive foundation assessment.

Lally columns are the steel or concrete-filled posts in your basement that carry the weight of your main support beam — and everything above it. They’re easy to overlook because they’re out of sight, but when a lally column is compromised, the consequences travel upward through your entire home: sloping floors, sticking doors, cracked drywall, and sagging beams are all common symptoms.

In older New England homes, lally columns are frequently found to be rusted from chronic basement moisture, improperly sized for the actual load they carry, or resting on deteriorating footings that have settled or shifted. A column that looks structurally intact on the surface may be quietly transferring an uneven load — and that stress compounds over time. Keller inspects your center support system as part of every foundation assessment, evaluating column condition, load-bearing capacity, footing stability, and the beam connections above.

Common Questions About Foundation Repair

How do I know if my foundation problem is serious?

Horizontal cracks and bowing walls are the most serious warning signs and warrant immediate professional evaluation. Vertical cracks may be less urgent but still require assessment. When in doubt, don’t wait — foundation problems worsen with every frost cycle and rain season. A free inspection costs you nothing.

How much does foundation repair cost?

The cost depends entirely on the type of problem, how far it has progressed, and which solution is appropriate for your foundation type and soil conditions. The best way to get an accurate number is a free on-site inspection — we provide written quotes with no obligation.

Will foundation repair lower my home's value?

Quite the opposite. Unaddressed foundation problems are one of the top deal-killers in real estate transactions. A professionally repaired foundation — especially one backed by a lifetime transferable warranty — is a selling point that sets your home apart and gives buyers confidence.

How long does the repair last?

Keller’s structural repairs are designed to be permanent. Our pier systems are driven to load-bearing strata and don’t rely on surface soil conditions. Our wall systems stop active movement and are built to hold for the life of the structure. Every repair is backed by our lifetime transferable warranty.

Do I need to leave my home during repairs?

No. Most foundation repairs are completed while the home is fully occupied. Our crews work efficiently and clean up thoroughly each day. The majority of pier and wall repair jobs are completed in one to two days with minimal disruption to your daily routine.

Can a bowing wall be straightened?

In many cases, yes — gradually. Steel I-beam systems can be incrementally tightened over time as seasonal soil changes allow the wall to move back toward plumb. The key is acting before the wall has bowed beyond a point where restoration is practical. Early intervention always yields the best outcome.

Don't Wait Until a Small Problem Becomes an Expensive One.

Foundation movement doesn't stop on its own. Every frost season and rain cycle adds to the damage. A free, no-obligation inspection gives you the facts — and the options — you need to make the right call.
