Our Services for You

Foundation Repair in Oakland

Your home’s foundation integrity is essential for overall stability. In Oakland, the unique blend of soils, from silt loam to gravelly loam and silty clay loam, impacts foundation stability due to their varying drainage properties. This region experiences over 20 inches of rain, leading to soil movement, erosion, and lack of support for foundations. Signs of these issues include drywall cracks and floor cracks, bowing walls, and uneven floors. Bay Area Underpinning offers durable, tailored solutions with warranties to reinforce your foundation. Our services include advanced pier systems, crawl space support, and other solutions, ensuring long-lasting foundation stability.

Crawl Space Repair in Oakland

In Oakland, where many homes are constructed over crawl spaces of 1 to 3 feet high instead of basements, these areas serve as crucial spaces for plumbing and ductwork. However, they are often prone to issues stemming from open vents and exposed dirt floors. Moisture, pests, and humid air can infiltrate these spaces, leading to mold growth, wood rot, and poor air quality that can affect the entire house through the stack effect. Bay Area Underpinning specializes in comprehensive crawl space repair services. This includes the installation of interior drains, sump pumps, dehumidifiers, thermal insulation, vapor barriers, and support posts, providing effective solutions to these common problems.

Concrete Lifting & Leveling in Oakland

The concrete on your property – including your patio, exterior steps, driveway, and sidewalk – is prone to damage over time due to Northern California’s specific soil and climate conditions. As the soil becomes compromised, your concrete structures may crack, sink, and become uneven, posing tripping hazards and detracting from your property’s value and appearance. Bay Area Underpinning offers an effective, durable solution with polyurethane foam injections. These injections are adaptable, non-toxic, minimally invasive, and cure rapidly, allowing you to use your concrete surfaces on the same day!

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.
