When a foundation settles unevenly, it affects the entire structure above it. Doors stick, floors slope, and cracks appear in drywall and brick. Underpinning transfers the weight of your home to stable soil or bedrock deeper underground, stopping settlement and often restoring the foundation to level.
How It Works
Sloping floors, cracks in brick or drywall, doors that will not latch, or gaps around window frames. These all suggest your foundation may be settling unevenly.
We connect you with a licensed professional who specializes in pier systems and foundation stabilization for your soil conditions and home type.
Your specialist evaluates the settlement pattern, often using a level survey, and recommends the right pier system with a detailed scope and quote.
Underpinning uses steel piers driven deep into the ground until they reach stable soil or bedrock. Push piers are hydraulically driven using the weight of the structure itself. Helical piers are screwed into the ground and work well in lighter structures or where soil conditions favor them. Once the piers are in place, the weight of the home is transferred from the shallow, unstable soil to the deep bearing stratum. In some cases, the foundation can be lifted back toward its original position. Slab jacking (also called mudjacking or polyjacking) is a related technique used to raise sunken concrete slabs by injecting material beneath them.
Underpinning is needed when the soil beneath your foundation can no longer support the structure. This happens due to poorly compacted fill soil, changes in moisture content (drought or plumbing leaks), erosion, or building on soil types that shrink and swell. If you notice progressive cracking, uneven floors, or doors and windows that increasingly stick or gap, your home may be settling.
Most residential underpinning projects take two to five days depending on the number of piers required and site access. The work is done from outside the home along the foundation perimeter, with small excavation points at each pier location. Interior disruption is minimal. Pier systems come with long-term warranties, often transferable to future homeowners.
Common Questions
Underpinning is needed when your foundation is settling unevenly due to unstable soil beneath it. Signs include sloping floors, cracks in walls or brick veneer, doors and windows that stick or gap, and visible sinking on one side of the home. A specialist can confirm settlement with a level survey.
Most residential projects are completed in two to five days. The timeline depends on the number of piers needed, soil conditions, and accessibility around your foundation. Your specialist will provide a project schedule during the assessment.
Properly completed underpinning with a transferable warranty can actually protect or increase your home's value. It demonstrates that a known issue has been professionally resolved. Buyers and home inspectors view documented foundation repair with a warranty as a positive, not a negative.
The cost depends on the number of piers required, pier type, and depth to stable soil. Residential projects typically range from $10,000 to $30,000 or more. Each pier costs roughly $1,000 to $3,000 installed. Your specialist will provide a detailed quote based on your specific situation.
