Other companies were trying to sell me on the bells and whistles pushing services I didn't really need. These guys were transparent and the pricing for the job came out about $500 less then the other quotes.

  • Does Foundation Movement Affect Concord, California?

    Unfortunately, much of the Bay Area is prone to ground movement that can have severe, adverse effects on home foundations. Property owners in Concord, Richmond, Berkeley, San Francisco, Palo Alto, San Jose, San Francisco, and many other cities nearby regularly deal with foundation problems and sometimes very costly repairs.

  • What Causes Foundation Problems In Concord, California?

    Several of the things that draw residents to Concord are also to blame for the high rate of foundation problems. We’ll explain each of the underlying causes of these damages below and the reason they’re so dangerous for your home.

    Expansive Soil

    Concord is situated on a soil variety called Clear Lake Clay. As the name suggests, the soil has a high concentration of clay. Clay soil is expansive, and it creates several issues for homes in the area.

    The first problem is that it dilates when it gets wet. When precipitation soaks into the earth, the soil swells and places added pressure on your foundation. The expansion puts inward force on your foundation walls and upward force on your slab. This hydrostatic pressure is often enough to crack the concrete, leaving you with structural damage and an easy entryway for water into your home.

    The second problem is more prevalent in Concord because of the naturally dry weather conditions. Expansive soil loses volume when it dries, so the soil around your foundation shrinks away from it during periods of little or no rain. The result is small voids forming around the concrete, sometimes leaving your slab without the support it needs and typically gets from the earth.

    Unsupported sections of your home’s foundation can collapse under the weight of your structure if this settlement occurs unevenly. The resulting damage from this differential settling can be very severe and often requires structural repair.

    The last problem with expansive soil is that it retains water for long periods between the tiny clay particles. Following rainfall or plumbing leaks, moisture is held against your foundation and has the opportunity to seep through cracks or pores in the concrete. Moisture problems and water intrusion are both an issue in Concord because of the soil’s absorbent qualities.

    Below-Average Rainfall

    The lack of heavy and frequent rainfall is one of the climatic factors residents love most about Concord. The city experiences just over 18 inches of rain each year, which is approximately half of the national average.

    The lack of precipitation throughout Contra Costa County leaves the soil excessively dry for most of the year. The extended periods of no rain make the risk of differential settling significantly higher.

    cracked dry soil

    The arid conditions punctuated by eventual rainfall create a dangerous cycle of dry and wet soil. The earth expands and contracts rapidly with the changes in moisture, and the frequent pressure and lack of support for your foundation during these changes can quickly create structural damage and instability.


    California residents are perhaps the most familiar with earthquakes in the country because of the location on the west coast near the San Andreas fault zone. Concord, in particular, is affected by five fault lines that run near and through the San Francisco Bay area.

    Earthquakes occur regularly in the city, and although most are small, even minor ground shifting can create problems. Quakes contribute to differential settling and can cause soil to shift and put undue pressure on your foundation.

    Most homes in Concord are built slab-on-grade because of the very shallow groundwater. In slab foundation construction, it’s common practice to run plumbing lines through the concrete slab. Frequent minor earthquakes or more intense, isolated shaking in the area can rupture the plumbing lines and cause them to leak into the ground.

    Plumbing leaks can cause several obvious problems, like water damage to your home and high utility bills. However, saturated clay soil under your property can cause foundation upheaval, which occurs when the ground under your slab swells and puts intense upward pressure on your concrete. This ground movement can cause massive damage and necessitate expensive structural repairs.


    Lastly, flooding is relatively commonplace in Concord for a few different reasons. Tidal floods can occur during heavy rainfall or when tides are elevated from storm surge.

    Tsunamis caused by earthquakes from the many faults near Concord can also raise water levels and lead to flooding. The clay soil in the city doesn’t allow runoff to drain through it readily, so any accumulation of water can be an issue for homes in the area.

    Flooding contributes to soil swelling and hydrostatic pressure that can compromise your foundation’s structural integrity. It also increases the risk of water intrusion, as the absorbent soil will hold the moisture against your porous concrete for extended periods.

  • What Are The Signs of Basement Foundation Damage In Concord, California?

    The many underlying causes of foundation damage in Concord can bring about various symptoms throughout your house. Below, we’ll discuss the more common warning signs that damage has occurred, and we’ll explain why each is likely to appear.

    Foundation Cracks

    Foundation cracks appear under most homes. They don’t always indicate serious issues, but they can suggest structural damage in some cases. It will be most helpful to break down the different types of fissures you may see under your home.

    Hairline Surface Cracks

    Most Concord foundations are slabs, so identifying surface cracks can be challenging unless you’re replacing or removing flooring in your home. If you are carrying out these home improvements, you’re likely to find thin cracks on the surface that span out from the edges of your home and potentially meet with other fissures.

    Provided these gaps are thin, they typically don’t indicate significant problems. They form most often in response to natural concrete settling in the years after the foundation is poured during new construction. Many homeowners opt to have them sealed by a foundation repair company to ensure water or moisture doesn’t enter through them.

    Wide or Unlevel Surface Cracks

    If the cracks you locate on your slab’s surface widen beyond ⅛”, have one side that is raised above the other, or are visibly allowing water into your home, the problem is more severe.

    These slab cracks form because of differential settling, a major concern in Concord due to the expansive soil and dry conditions. They usually require structural repair and stabilization, as well as an epoxy or polyurethane sealant.

    Cracks on Foundation Corners

    Cracks on the outside of your slab are easier to identify because they aren’t covered by other building materials. You may notice fissures that span the corner of your structure or appear in a diagonal orientation near the corners. These areas of your foundation are most prone to differential settling, so cracks located there should be inspected by a structural engineer to determine the cause.

    It’s possible that these gaps are from settling, but they more likely suggest dangerous settling that could result in structural damage.

    Vertical Slab Cracks

    Thin gaps in a vertical position on the outside of your slab are commonplace, and they usually aren’t cause for concern. They are almost always from typical foundation settlement. Some homeowners choose to have them sealed, but further repair and stabilization are very rarely needed.

    Crawlspace or Basement Wall Cracks

    If you have a crawlspace or basement, you may notice horizontal cracks or gaps in the shape of stair steps on your foundation walls. Horizontal cracks are clear indications of excess hydrostatic pressure and can lead to foundation failure if left untreated. Stair-step cracks usually signify differential settling and structural damage, so they also need to be treated immediately to prevent more significant problems.

    Poor Indoor Air Quality & High Water Bills

    Foundation cracks, flooding, and plumbing damages caused by earthquakes in Concord can all contribute to water and moisture build-up between your slab and your first floor. The resulting increased humidity in your home can make the air temperature feel more extreme, so uncomfortably hot or humid conditions in your house can indicate a water or moisture problem.

    The humidity caused by a leaking foundation can also promote mold growth, so musty odors or allergy symptoms in response to mold spores in the air can also be signs of foundation issues.

    Plumbing breaks and underground leaking may go entirely unnoticed in your living space, but they often result in unexpected increases in your water bill.

  • How to Find Signs of Foundation Damage In Concord, California?

    The concrete under your home is under constant stress from the weight of your structure and the ground movement common in Concord.

    As such, problems with your foundation tend to worsen over time. Identifying and correcting foundation problems early can help limit property damage and repair costs. Below, we’ll provide a thorough home inspection you can carry out every few months to monitor for changes and signs of an issue.

    Inspect Your Foundation Thoroughly

    You can begin your inspection by examining the concrete under your home. If you are able to expose the top surface of your slab from inside your home, look for hairline cracks, wide or uneven cracks, and signs of leaking. If you don’t have access to the majority of your foundation, you can inspect the garage slab for signs of cracking, as this area is typically exposed and easy to examine.

    More likely, you’ll only have easy access to the foundation’s exterior. Look for gaps visible outside your home, particularly around the corners of your property. Look for signs of sinking or uneven concrete as well, as these can indicate dangerous settling.

    Check the Interior of Your Home

    Your home’s foundation should provide a level and sturdy base for the rest of your house, so damages will often exhibit symptoms in your living space. Walk through your home next and look for warning signs of damage.

    Foundation movement can shift the framing behind your walls, which often results in damages to the sheetrock. Look for cracks in the drywall, leaning or bowing walls, nails bulging out of the sheetrock, and multiple doors or windows that get stuck.

    Your floor joists rely directly on the slab for support, so buckling and sloping floors in your living space are reasonable indications of differential settling.

    You should also take this time to check your water bills for unusual increases, a potential sign of underground plumbing leaks that can wreak havoc on your foundation over time.

    Check Your Home’s Exterior

    Finally, you may be able to identify foundation problems based on changes to your home’s exterior and symptoms evident in your landscaping.

    Siding cracks, sagging roofing, and a cracked, crumbling, or tilting chimney can all suggest differential settling or foundation upheaval below.

    Gaps between the earth and your foundation can indicate that the dry clay soil is pulling away from your concrete, meaning differential settling may be a problem on your property. Leaning retaining walls or pooling or puddling water during rainfall or flooding suggests that expansive soil is prevalent around your home and could cause foundation damages if left untreated.

  • Cost of Basement Foundation Repair In Concord, California?

    Foundation solutions in Concord cost homeowners an average of $5,000. Minor issues may cost just a few hundred dollars, while more severe damages can run the repair bill into the multiple tens of thousands. We’ll break down pricing for the common foundation repairs in the Bay Area below.

    Cost to Seal Settling Cracks

    Thin surface cracks or vertical slab cracks that aren’t structural are generally the most straightforward damages to repair. Most general contractors charge between $300 and $800 for this concrete repair, depending on the crack’s size and ease of access.

    Cost to Correct Differential Settling or Sinking Foundation

    Larger slab cracks that are structural in nature usually require underpinning. This concrete leveling technique displaces the weight of your structure further into the earth, where uneven soil shrinkage is less of a problem. Foundation repair contractors in Concord generally use helical piers that cost around $3,000 each. Your total cost for this service can fall anywhere between $10,000 and $20,000.

    Mudjacking or foamjacking can also be used to level smaller areas of concrete. They cost significantly less at around $2,500, but they aren’t always a permanent solution and typically don’t include a warranty. They typically aren’t ideal for solving structural problems, but they can be acceptable for raising sinking portions of a garage floor.

    Cost to Repair Foundation Leaks

    A leaking foundation may require a waterproofing system to reduce the amount of moisture that comes in contact with your concrete. These systems for slabs typically include an exterior drainage system, vapor barriers, gutters, leaders, and gutter extenders. The average cost is approximately $3,000.

    If you have a crawlspace or basement, you may also need sump pumps, dehumidifiers, and crawlspace encapsulation. The price for a more comprehensive basement waterproofing system can run up to around $10,000.

    Plumbing leaks under or inside your concrete slab typically cost between $500 and $4,500. The size of the leak and the ease of access will determine where in that range your repair falls. The average price is around $2,500, but yours may be higher if additional foundation solutions are needed.
