Foundation settling and cracking may cause serious structural issues as well as a decrease in the value of your house. Repairing a home’s foundation is time-sensitive; if it is not done promptly, it can lead to unrepairable issues and make the structure dangerous to live in.

The majority of Foundation Repairs cost between $5,000 and $10,000 to complete. Over time, all houses settle, but if yours settles too much, it can cause severe structural issues. Piering and underpinning concerns might cost anything from $1,000 to $2,000 per pier to correct. They put between 8–10 piers typical in a house.

Concrete piers take 2–5 days to install. Cracks can be repaired in as little as half a day. Major repairs, such as rebuilding a house’s foundation, might take several weeks.

Some foundation cracks are natural, but others must be repaired before they cause serious harm. Cracks are repaired by injecting epoxy, which costs between $500 and $800 for each crack. The cost of labor for any technique of repairing your concrete foundation will be between $100 and $200 per hour.

Fix Foundation Problems Estimated Costs

Poor soil strength beneath the foundation, expansive clay, inadequate drainage, and poor grading before the foundation was built cause foundations to move and settle over time. The following are the most common foundation issues that must be addressed:

Costs To Fix Slab Foundation

Cracks $500 – $800 per crack

Leaks $2,500 – $5,000

Settling / Sinking $1,500 – $2,000 per pier

Bowed Basement Walls $5,000 – $15,000

Foundation Crack Repair Costs

Flexible epoxy injections can be used to Fix Foundation fractures over 1/8″ broad, costing $250 to $800 per crack. However, the more important question is why the fracture formed in the first place. This problem must be handled in order to prevent the emergence of more significant issues. To prevent water from leaking through, hairline fractures in the foundation should also be addressed.

Cracks can be filled using epoxy with a minimum bond strength of 7,000 PSI to prevent them from developing and to keep water out. The epoxy resin is poured through injection holes drilled every 4″ to 8″ along the fracture.

Setting an injection port, flushing out debris, and inserting the epoxy will cost $21 per port. Thus a 10′ fracture will require 29 ports drilled and filled at the cost of roughly $620. You can estimate foundation injection expenses by measuring the length of each crack in your foundation and adding them together.

Foundation Leak Repair Estimated Costs

Any leaks in the basement or foundation must be repaired and waterproofed, which will cost between $2,500 and $5,000 on average.

Water pressure that is too high might corrode the foundation and cause the walls to fracture. Install a sump pump backup if your home floods every spring or summer. This will ensure that all water is pushed out of the house at all times, no matter how much water is present. On average, sump pump installation costs between $490 and $1,170.

Sinking Repair Estimated Costs

Installing concrete piers beneath the foundation and then lifting them to hold the home at the correct level is the best approach to remedy a sinking foundation in most cases. The cost per pier ranges from $1,300 to $1,500. A structural engineer report, which costs $300–$1,500, is one of the tests that determine the optimum restoration technique.

The engineer will figure out how many piers are needed and where they will go. You could require a $500–$3,000 soil study, as well as $75–$150 in permits.

Bowed Basement Wall Repair Estimated Costs

Carbon fiber strips put to the wall with industrial grade epoxy can be used to fix a wall that has bent less than 2 inches. Steel strips will need to be placed and attached to the floor joists if the wall has shifted more than 2″. This may cost up to $15,000.

Another option is to use wall anchors. Anchor plates are dropped into a trench excavated around the outside of the home. Steel connecting rods are put into the anchors and secured with an anchor bolt and washer to a wall plate fitted on the interior of the wall. The connecting rods have been snugged up. Continue to tighten the rods overtime to help the wall become straight again.

How To Fix Foundation Problems

Your Foundation Repair alternatives will be determined by the reason for foundation collapse and the type of foundation you have, which will affect your overall cost. Fixing foundation issues necessitates the expertise and experience of a qualified contractor who can ensure the foundation’s best performance for years to come. The sooner the difficulties are treated, the less expensive they will be, and further problems will be avoided.

Most Common Foundation Repair Methods

  1. Underpinning and Piering
  2. House Leveling
  3. Sealing
  4. Home Stabilizing

Underpinning and Piering

Piering and underpinning can cost anywhere from $1,000 and $3,000 per pier, not counting the cost of raising the home, excavation, and installation. Piering is a long-term solution that involves putting supports below the home at various locations.

To support the foundation, contractors excavate beneath the house and install hydraulically raised piers. A typical home has eight to ten piers.

House Leveling

On average, house leveling or mud jacking costs between $600 and $1,800. Mud jacking, also known as slab jacking, is a non-invasive way of shoring up the earth beneath a house or construction. It should be handled by an expert.

They’ll inject a grout or polyurethane mixture into the region that needs raising through ports drilled into the foundation, and the liquid will float the foundation back to level. The cost of drilling each hole for the grout mixture is $150, plus the cost of the grout mixture and labor. For smaller slabs, slab jacking is a viable option.

House Foundation Leveling 


Water is seeping in through the foundation from the earth, drain tile is clogged, downspouts are clogged or damaged, or water is collecting around the foundation if you have moisture problems in the basement. One option is to use a tar-like material to seal the foundation.

To get access, the ground around your property will need to be dug, and then the sealer will need to be applied. Basement waterproofing and sealing might cost anywhere from $1,920 to $6,320. You may also solve the drainage problems by repairing or replacing your gutters.

Home Stabilizing

A carbon-fiber mesh is the most frequent way of strengthening foundation walls that are unstable. Mesh is attached to the wall with industrial-strength epoxy, and depending on the degree of the damage, it should cost between $5,000 and $10,000.

To restore a wall’s vertical alignment, use wedge braces and jack posts. If necessary, include the cost of removing and restoring wall finish materials. To alleviate the weight on a load-bearing wall, vertical jacks may be required. Once the wall is plumb, add the cost of adding wall straps and sheer panels.

Signs of Foundation Problems

A skilled contractor will need to check the foundation and surrounding area before you can receive an accurate estimate of the cost of Foundation Repair. Without actually viewing the project, it is impossible to provide an exact estimate. The following items will be examined by the contractor:

The only way to tell whether your house has foundation issues is to read the signs it provides you, such as:

  • Wall fractures on the outside
  • Foundation fractures that run horizontally
  • If you have a basement, there may be water in it.
  • There may also be jagged fissures in the foundation or walls.
  • The cracks’ severity, as well as their location in relation to the rest of the home and the number of them.
  • Bowing or bulging walls
  • Concrete that is crumbling
  • The drainage systems that are currently in existence
  • Soil problems with a lot of clay
  • Bricks with cracks
  • At the corners of the garage door, doors, and windows, there are cracks or separations.
  • When you try to open a window, it becomes stuck.
  • Cracks in the sheetrock are a common occurrence.
  • Cracks in the floor
  • Floor cracks and doors that are difficult to close or do not close
  • Floors with bulges

Foundation Damage Prevention (Sealing the Foundation)

Keep a watch on the water/sewer pipes to make sure they aren’t leaking if you want a strong foundation. Leaking pipes will eventually create erosion, which might cause Foundation Problems. The earth will lose its ability to sustain a building if it becomes saturated and stays that way.

Because the pipes are under the home, it’s possible for water damage to develop and go undetected. A higher-than-average water bill generally indicates the presence of such a leak. You may also have the plumber run static checks on your water pipes to be proactive with water lines.

Too much or too little water can both be problematic. When watering your grass during the dry seasons, make sure to hydrate the foundation as well. Look for locations where the earth is pushing away from the foundation and water those areas.

Foundation Inspection Cost

If you believe that your foundation is damaged or that repairs are required, have a structural engineer evaluate your property. A structural engineer’s report will cost between $200 and $400.  They will look for evidence of distress, water damage, and degradation in all visible areas of the foundation, basement, and crawl space.

Because they aren’t attempting to sell you anything, a structural engineer’s assessment may be trusted. This isn’t to imply that contractors will fix something that isn’t broken, but unbiased advice from experts is always beneficial.
