Average Cost of Foundation Repair

Cracks are one of the most common issues with home foundations and are caused by the building settling or the soil around the foundation putting pressure on it. Cracks in the foundation or changes in soil pressure can cause water damage or bowing walls. Changing weather conditions, erosion, or even nearby tree roots can cause a foundation to begin to sink. Changes in soil pressure can also cause the walls of your foundation or house to bow.

There are a number of different issues that can occur with foundations, some of which are more costly and difficult to repair than others. While you may be able to have very small cracks filled with epoxy for a few hundred dollars, severe foundation problems can run you  $15,000–$25,000. Overall, the cost of foundation repair tends to be between $2,000 and $7,500, with a national average of $4,500.

The table below shows what you can expect for different price ranges according to the scope of your foundation repair projects.

Factors in Calculating Foundation Repair Cost

The type of foundation repair that you need and the issue with your foundation are just two of the factors that determine the price you’ll pay for repairs. Major factors in calculating your foundation repair cost include:

  • Home size and accessibility
  • Severity of the foundation issue
  • Soil stability and foundation settlement
  • Labors, permits, and materials needed

To have an accurate understanding of what your repair may cost, you’ll want to have a grasp on these considerations.

Home Size and Accessibility

It’s no surprise that larger homes have larger foundations and thus tend to cost more to fix. However, the accessibility of your home’s foundation also plays a role in the price of a repair. If the problem area or the whole home is difficult for workers to reach, landscaping may have to be removed and replaced, increasing the overall cost of the project.

Severity of the Issue

Unsurprisingly, minor cracks are much easier and cheaper to fix than a sinking foundation. However, catching any of the types of foundation problems early will save you money. The more severe a home’s structural problems become, the more damage they can cause to the rest of the house. In later stages of foundation problems, you may find yourself having to repair cracks in interior walls and floors as well.

Soil Stability and Foundation Settlement

The phrase “solid ground” may be slightly misleading—soil expands, contracts, and shifts depending on weather and drainage conditions. Some types of soil are more stable than others, and ideally, your house is built on the right foundation type for the ground it’s on. However, foundations built on expansive clay or poorly-draining soil will experience more severe settlement. If you find yourself dealing with these soil types, your foundation may require more extensive repairs.

Labors, Permits, and Materials

Beyond just the pilings, filler material, polyurethane foam, or waterproofing sealant that go into fixing a foundation, you also have to consider the cost of labor. Work on a foundation repair averages around $200 per hour. You may be able to perform minor foundation crack repair without needing permission from the city, but bigger repair jobs are usually substantial enough to require $75-$150 in permits.

Additional Foundation Repair Costs and Considerations

Once you’ve determined your foundation issue and type along with the pricing factors listed above, there are a few more aspects to consider. Foundation repair is one of the most extensive home projects, and some homeowners will also need a soil or structural engineer report, detailed below.

Unexpected problems can also pop up, delaying your timeline or increasing your total price. However, these additional costs aren’t typical for minor repairs.

Soil Report

Even if your home was built on an ideal foundation for the surrounding soil type, the soil conditions may have changed over the years. If they’ve changed substantially, you may need to hire a geotechnical engineer to complete a soil report. These reports usually cost $500$3,000. While soil reports are typically completed before new construction occurs, they can sometimes provide a better picture of what’s causing the problem with your foundation and how to solve it.

Structural Engineer Report

Structural engineers are consultants who specialize in buildings’ structural integrity. In advanced cases of foundation damage, you may need to have a structural engineer inspect your home and its foundation and write up a report on any problems. This report can cost anywhere from $300–$1,500.

Unseen Obstacles

As with any substantial home improvement project, you might not know exactly how extensive the job is until you start it. There may be unexpected tree roots or the remains of old repair jobs which need to be cleared away. It’s always a good idea to have at least $1,000–$2,500 extra in your budget to cover these unplanned costs.

Types of Foundations

The type of foundation you have will determine what problems you might face and how to best solve them. The most common types of foundations include a concrete slab, crawl space, cinder block and brick, basement, and pier and beam.

  • Concrete slab: A concrete slab foundation is a layer of concrete that rests atop the soil and is usually between 4 and 8 inches. These are usually found in warmer climates since freezing and thawing of the soil can make even a thick concrete slab crack over time. Homes with concrete foundations don’t have basements or crawl spaces, and though this means no underground leaks and fewer pest problems, it also means the drainage system must be embedded right into the concrete.
  • Crawl space: This unfinished, unheated space may house a furnace or pipes for the house and even act as storage space. A properly built crawl space is well-ventilated to prevent moisture from building up and causing problems beneath the house. Crawl space foundation walls are typically built of poured concrete or concrete blocks, which may develop cracks. Crawl space issues are a little easier to address since there’s space to access the underside of the home.
  • Cinder block and brick: A foundation may comprise cinder blocks or bricks with mortar in between. Often, the blocks are laid in an overlapping pattern and grouted with steel rods. This method provides the stability of a concrete slab while allowing for more compression and expansion than solid concrete. A foundation made of cinder blocks or bricks with mortar may crack, leak, or bow along mortar lines. Extensive waterproofing and sealing is required to prevent moisture. Steel or carbon fiber can reinforce the blocks’ stability, but you should fix drainage issues first.
  • Basement: A full basement foundation is one of the most expensive types to build, involving the most excavation and construction. However, a basement also expands the home’s livable area and is more suited to climates where the ground freezes in the winter. Foundation footings support it under the perimeter of the space that extends into the ground deeper than the frost line. Unfortunately, basement foundations are some of the most expensive to repair.
  • Pier and beam: Pier and beam foundations allow a home to sit several feet above the ground, creating an open-air crawl space that allows easier access to plumbing and electrical fixtures. Often, the piers, made of metal, concrete, wood, or brick, will rest on concrete footing buried deep underground. Here, they won’t be affected by shifting or pressure in the surface soil. The piers are then connected to support beams, which are, in turn, connected to the house’s floor joists.

Signs You Need Foundation Repairs

Spotting the signs early can save you thousands of dollars if you suspect foundation damage in your home. The longer foundation issues persist, the more damage can occur in other areas of your home. Here’s what to look for around the house to identify foundation problems:

  • Early signs: Fractures or cracks in the foundation are early signs of damage. However, not all cracks are serious. Vertical cracks, especially small ones, are considered minor. You should patch them to prevent further damage, and the good news is that they’re usually not a sign of more significant problems. Horizontal cracks, on the other hand, are signs of an unstable foundation. These need to be examined by a professional so you can find a permanent solution.
  • Exterior signs: If you suspect you may have foundation problems, walk around outside your home and inspect the foundation and exterior walls for cracks. You can also observe whether there’s a gap between the foundation and the soil around it, which may be a sign that the soil has shifted. Keep an eye out for changes in the soil, particularly if you live on an incline, as well as any damp areas or water pooling around your home. Remember that drainage problems are a substantial cause of foundation damage.
  • Interior signs: Check the inside of your home and its walls for cracks. There may be more subtle signs, too, like doors or windows that don’t open or close properly and gaps in doorframes or between walls. If the walls are bowing, nails may start working out of drywall, and ceilings may begin to warp. An uneven or sinking foundation can cause your home’s flooring to slope, bulge, gap, or crack. Finally, water damage or pooling water in the basement or crawl space can indicate a foundation leak, so you should address them immediately.

DIY vs. Professional Foundation Repair

Most of the time, you can’t attempt foundation repair on your own. If you find small, vertical cracks no wider than one-eighth of an inch, you can purchase epoxy and try to seal them yourself. However, larger cracks need to be assessed by a professional at the very least. Foundation repair companies often provide free inspections of potential problems.

Even experienced home improvement enthusiasts won’t have the necessary equipment to address serious foundation issues. A sinking foundation may require the whole house to be held up on jacks, and heavy machinery may be needed to excavate the area around the home to access the foundation. Although it may be expensive, hiring a professional contractor to fix your foundation can keep the problem from worsening or causing more damage to the rest of the house.

Professional Foundation Repair

When and why is it better to use professional foundation repair companies? Below, we outline common foundation problems that are difficult to fix yourself. As an example, we’ll explain how Groundworks, a top foundation repair company, would handle the situation.

  • Basement waterproofing: If you have a leaking water heater or notice a musty smell in your basement, you can contact Groundworks to get a foundation repair technician to assess the situation. Based on their expertise, Groundworks creates a plan of action to remove excess moisture from your basement and then waterproof the area to prevent further damage. Some solutions include a sump pump and dehumidifier installation, which professionals can install for you. Other options include adding new drainage systems to your home or installing a new egress window
  • Concrete lifting: Like its other foundation repair services, Groundworks provides professionally-seasoned foundation repair technicians to assess any concrete cracking or sinking you notice. However, unlike some DIY options for concrete lifting like mud jacking, Groundworks has access to polyurethane injections, which are less time-consuming, invasive, and expensive. It takes a professional to understand how to use this mixture correctly, but you’ll be able to use your driveway or other concrete surfaces just 15 minutes after installing the polyurethane foam.
  • Crawl space repair: When you opt for a professional foundation repair company to handle crawl space repairs, you won’t have to crawl around a dangerous and uncomfortable space in order to handle this sensitive repair. Groundworks offers many solutions to crawl space repair as basement waterproofing, such as dehumidifier and drainage system installation. In addition, the company provides more complex repairs, such as crawl space encapsulation with its meticulously designed CrawlSeal vapor barrier. These repairs can prevent future foundation issues due to moisture.

The best reason to hire a professional foundation repair company like Groundworks is to receive a proper structural engineer report on your home’s foundation problem. This approach can avoid costly errors. Based on your report, professional companies like Groundworks will offer solutions that are not typically DIY-friendly, such as helical pier installation and carbon fiber wall reinforcement. These standard solutions require expertise and careful execution to keep you and your family safe, so we recommend you use a professional for your foundation repairs.

How To Save Money on Foundation Repair

Foundation repair is expensive, and you may be tempted to try to cut corners to save money. However, your investment in your home is too important to risk subpar repairs. It’s worth comparing quotes from several local contractors to find a good deal without sacrificing workmanship.

  • Ask about less expensive repair methods: Ask if injecting polyurethane foam or epoxy into the cracks is an option instead of completely replacing the foundation if you have minor settling or cracking. Less invasive methods can cost thousands less.
  • Consider used materials: Check with the foundation repair company if it can use some used bricks or stones to reduce material costs when repairing a brick foundation. The structural parts should be new, but aesthetics can use previously used materials.
  • Fix the root cause: Make sure to fix any drainage or landscaping issues causing the foundation problems. Ensure your drainage system, including gutters and downspouts, properly directs water away from your foundation. Focus on the root cause of the problem with a foundation repair technician rather than fixing the symptoms.
  • Get a warranty: A reputable company will stand behind its work with a warranty that protects you if any issues arise.
  • Get multiple quotes: We recommend you ask numerous foundation repair companies for quotes. Foundation repair can be expensive, so get quotes from several companies before choosing one. Make sure all the quotes are for the same scope of work.
  • Negotiate the price: Don’t be afraid to negotiate, especially if you’re getting multiple quotes. Stress your budget constraints and see if they can shave some dollars off their quotes.
  • Schedule during the off-peak seasons: Foundation repair companies are less busy in the winter in colder climates. You may get discounted rates if you schedule the work during their slower months.
