How Much Does It Cost To Fix A Cracked Foundation?

Table of Contents

    Foundation cracks can be alarming and costly, but homeowners must understand the potential expenses. Fixing a cracked foundation varies widely, from minor repairs costing around $500 to more severe damage exceeding $10,000. 

    Factors like the size and severity of the crack, repair methods, and the home’s foundation type all affect the total cost. 

    This guide will help you navigate the complexities of foundation repair, breaking down common repair methods, associated costs, and factors that influence pricing to help you make informed decisions.

    Let’s get straight to the point.

    Repairing a cracked foundation can cost between $500 and over $10,000, depending on the severity of the damage, repair methods (such as epoxy, mud jacking, underpinning, or reinforcement), and factors like foundation type, labour, and materials. 

    Minor repairs are cheaper, while serious damage requires more expensive solutions like steel or carbon fibre reinforcements. 

    Addressing cracks early can help avoid more costly repairs in the future. Soil conditions, home size, and accessibility also affect the overall cost.

    The Real Cost Of Fixing A Cracked Foundation

    The cost of fixing a cracked foundation can vary widely depending on the extent of the damage and the repair method needed. Below is an overview of the potential costs for different types of foundation repairs:

    1. Minor Crack Repairs

    Small vertical cracks that don’t indicate structural damage can be repaired for as little as $500. These are often fixed using epoxy or polyurethane foam to seal the crack and prevent further water damage.

    • Affordable and quick: Minor cracks are inexpensive to repair and can often be fixed daily.
    • Prevents water infiltration: Sealing cracks early can stop moisture from entering the foundation, avoiding larger issues later.
    • Non-invasive: The repair process does not require major disruption to the home’s structure.

    2. Mud Jacking Or Slab Jacking

    If the foundation has settled unevenly, a grout mixture can be injected under the slab to raise it back to its original position. This method, called mud or slab jacking, typically costs between $500 and $1,300.

    • Quick and effective: The process usually takes only a few hours and can fix minor uneven settling.
    • Less expensive than full replacement: This method is more budget-friendly than replacing an entire foundation.
    • Best for minor settling: Mud jacking is suited for smaller areas with uneven settling rather than extensive damage.

    3. Underpinning Or Piering

    More extensive foundation damage, such as significant settling or sinking, may require the installation of hydraulic piers to stabilise the home. This process, known as underpinning or piercing, costs between $1,000 and $3,000 per pier.

    • Strong, long-lasting solution: Piers provide deep stabilisation by anchoring into stable soil or bedrock.
    • Tailored to the home’s needs: The number of piers needed depends on the size and severity of the foundation issue.
    • Higher upfront cost: This option is more expensive but essential for severe settling or sinking.

    4. Reinforcement With Carbon Fibre Or Steel

    When foundation walls begin to bow or crack, carbon fibre or steel reinforcements may be needed. Carbon fibre strips cost between $4,000 and $7,000 for installation, while steel reinforcement beams for more severe damage may cost up to $12,000.

    • Carbon fibre for mild issues: It’s less invasive and ideal for less severe bowing or cracking.
    • Steel beams for serious damage: Steel is stronger and needed for significant wall bowing.
    • The durable, long-term fix: Both methods offer strong and lasting support for foundation walls.

    5. Waterproofing And Sealing

    Waterproofing may be necessary if the crack has allowed moisture to enter the home. Depending on the severity of the moisture issue, the cost of waterproofing a foundation ranges from $2,000 to $7,000.

    • Prevents future water damage: Sealing the foundation keeps moisture out and protects against mould and other damage.
    • Necessary for wet climates: Homes in rainy or flood-prone areas benefit greatly from waterproofing.
    • Multiple methods available: Solutions range from exterior waterproofing to installing internal drainage systems.

    Factors Affecting The Cost Of Foundation Repair

    1. Extent Of Damage

    The more severe the foundation crack or damage, the higher the repair cost. Minor cracks that do not affect the home’s structural integrity can be repaired for a few hundred dollars. 

    However, major cracks or significant structural damage can lead to costs in the thousands of dollars. The type of crack—vertical, horizontal, or diagonal—can also impact the cost.

    2. Type Of Foundation

    The type of foundation your home is built on can significantly impact the repair cost. Homes with slab foundations may require mud or slab jacking, while homes with basements or crawl spaces might need more extensive work, including excavation and reinforcement.

    • Concrete Slab: Depending on the severity of the settlement, repairs usually involve mud jacking, sealing, or piers.
    • Crawl Space: These foundations can develop moisture problems, leading to the need for joist or beam reinforcement, which is often lower cost than slab repairs.
    • Basement: Basement foundations are often more expensive due to issues such as bowing walls or large cracks.

    3. Labour And Permits

    Labour costs vary by location but typically average around $200 per hour. The time required to fix a foundation will depend on the complexity of the problem and the repair method. 

    In addition, some repairs may require building permits, which typically range from $75 to $150, depending on your local council’s regulations.

    4. Materials Used

    The overall cost also depends on the type of material needed for foundation repair. Common materials include epoxy, carbon fibre, steel beams, and hydraulic piers. 

    Each of these materials comes with different price points and uses:

    • Epoxy and Polyurethane Foam: Typically used for minor cracks, with costs starting at $500.
    • Carbon Fibre Strips: Used to reinforce walls, costing $4,000 to $7,000.
    • Steel Beams: Necessary for more extensive and expensive damage, often up to $12,000.
    • Hydraulic Piers: Used in underpinning, costing $1,000 to $3,000 per pier.

    5. Soil Conditions And Drainage Issues

    The soil around your home plays a critical role in the stability of the foundation. Homes built on clay or poorly compacted soil may be more prone to foundation movement and cracks. 

    Addressing underlying soil issues, such as poor drainage, may be necessary to prevent future foundation problems. However, these additional repairs will increase the overall cost of foundation repair.

    6. Home Size

    The larger the home, the more labour and materials are needed to repair the foundation. Larger homes also pressure the foundation, potentially leading to more extensive repairs. 

    A larger home may also require more piers or reinforcement beams, increasing the cost.

    7. Accessibility Of The Damaged Area

    The ease of access to the damaged area also affects the cost of foundation repairs. If the foundation crack is difficult to reach—such as in a basement or a home with extensive landscaping—the repair may require more time and labour, thus increasing the overall cost.

    Conclusion

    Foundation repair costs can vary greatly depending on the extent of the damage, the type of foundation, and the repair method required.

    Homeowners can expect to pay anywhere from $500 for minor crack repairs to over $10,000 for more extensive repairs involving underpinning or reinforcement. Addressing foundation cracks early is essential to avoid more costly repairs in the future.

    By understanding the factors that affect the cost of foundation repair and working with a qualified contractor, homeowners can make informed decisions to ensure the longevity and safety of their homes.
