Our Services for You

Foundation Repair in Sacramento

Maintaining the integrity of your home’s foundation is crucial for its overall stability. In Sacramento, a variety of soils, from silt loam to gravelly loam and silty clay loam, can affect foundation stability due to their different drainage properties. This area, receiving approximately 18 inches of rain annually, experiences soil movement, erosion, and compromised support for foundations. Indicators of these problems include drywall cracks and floor cracks, bowing walls, and uneven floors. Bay Area Underpinning provides robust, customized solutions with warranties to strengthen your foundation. Our services include advanced pier systems, crawl space support, and other solutions, guaranteeing enduring foundation stability.

Crawl Space Repair in Sacramento

In Sacramento, numerous homes are built over crawl spaces ranging from 1 to 3 feet in height instead of basements. These spaces are vital for accommodating plumbing and ductwork. Challenges often arise from open vents and bare dirt floors, leading to moisture, pests, and humid air penetration. This can result in mold development, wood decay, and deteriorated air quality, impacting the whole house through the stack effect. Bay Area Underpinning excels in providing complete crawl space repair services. We install interior drains, sump pumps, dehumidifiers, thermal insulation, vapor barriers, and support posts to effectively address these prevalent issues.

Concrete Lifting & Leveling in Sacramento

Your property’s concrete elements – such as patio, exterior steps, driveway, and sidewalk – can suffer damage over time due to the specific soil and climatic conditions of Northern California. Sacramento, experiencing over 18 inches of rainfall annually and characterized by a mix of sandy loam and clay soils, often faces issues with instability and erosion. As the soil deteriorates, your concrete may crack, sink, and become uneven, posing tripping hazards and reducing your property’s value and aesthetic appeal. Bay Area Underpinning proposes an efficient, long-lasting solution with polyurethane foam injections. These injections are flexible, non-toxic, minimally invasive, and quick to cure, enabling immediate use of your concrete areas after treatment.

Find Your Service Area


Properly repaired foundations can restore or even enhance the value of a home, especially in a competitive market like the Bay Area Underpinning.

Common methods include installing foundation piers and adding or adjusting support beams and screw jacks.

Concrete driveways sink, crack, and sustain other damage due to erosion beneath the slabs caused by expansive soil, soil instability, water intrusion from cracks, and growing tree roots. Heavy vehicles parked in the same place for extended periods can also cause driveways to sink. Contact Bay Area Underpinning for a free inspection to determine the source of the problem and the best solution.

It’s advisable to have a professional assess and fix any floor cracks promptly. The sooner you identify and address floor cracks, the easier and more cost-effective the solution will be.

Some of the most common issues and challenges associated with crawl space foundations are:

  • Moisture – Unless you live in a highly arid region, your crawl space will be prone to moisture-related problems. Excess moisture in a crawl space can lead to mold growth, wood rot, and structural damage.
  • Pests – Damp, dark crawl spaces also provide an ideal habitat for rodents and termites.
  • Poor Insulation – Since the crawl space isn’t livable, many homeowners may overlook proper insulation, leading to energy loss and higher utility bills.
  • Structural Damage – Poor foundation design, inadequate support, and soil movement can cause structural damage to a crawl space foundation over time, leading to cracks, uneven settlement, and other issues.
  • Poor Indoor Air Quality – A damp, moldy crawl space can lead to poor indoor air quality, including unpleasant odors, allergens, and other contaminants that can affect the health of the home’s occupants.
