Common Causes of Foundation Problems in O'Fallon

Foundation issues have a few possible causes. Here are the top ones for O'Fallon residents:

  • Standing water: Water accumulation around your home can threaten your foundation's integrity, especially when it collects in areas your gutter system doesn't reach.
  • Aging plumbing: While many O'Fallon homes are fairly new, some still use cast-iron plumbing. When the pipes start to erode, leaking water could reach your foundation and even pool beneath it.
  • Improper modifications: Roofing or landscaping work that wasn't done to standard could lead to your foundation settling.
  • Tree Roots: Tree roots can enter a home's foundation through cracks, and may create stress that causes your foundation fracturing, pipes rupturing, and overall structural destabilization.

How to Choose the Best Foundation Repair Company

Your home's foundation is vital to its stability, so it's important to work with a quality foundation repair firm. Evaluate each firm using the following factors:

Licensing and Experience

Missouri doesn't issue contractor licenses, but foundation repair companies must still register with the Secretary of State. Local governments often have their own licensing requirements for contractors. You can also get a sense of a company's experience through what its representatives say. Inquire about its inspection methods, local code requirements, permit-pulling procedures, and fees.

One of the simplest ways to evaluate a company's reputation is to visit its website. Look for how long the company has operated and the qualifications its team holds. Many leading companies offer educational content for future customers.

Customer Reviews

When you're researching a company's credibility, head to its Better Business Bureau (BBB) profile. There, you can find its "letter grade" rating and a list of customer reviews, both complaints and positive experiences. Complaints don't mean a contractor is unreliable. BBB reviews show how the company addressed complaints. It's a good sign if the company has fixed issues favorably and proactively. You should steer clear of a company with numerous negative reviews, no certifications, and no communication regarding issues.

Foundation Repair Cost in O'Fallon

The cost of foundation repair can range widely depending on the extent of the issues and what needs to be done to fix them. For minor foundation fissures and settling issues, you may pay as little as $1,800. However, if there is more significant deterioration, the average cost will likely fall around $2,500. More complex jobs involving tunneling, helical piers, or concrete leveling could cost $6,700 or more. See below the average foundation repair costs for common issues.

Frequently Asked Questions About Foundation Repair in O'Fallon

How much does foundation repair cost in O'Fallon?

You could spend about $2,500 on materials and labor for your foundation project. Ultimately, your expenses will depend on your specific needs and the extent of the foundation damage.

What are some signs I need foundation waterproofing?

You'll typically need to waterproof your foundation when you see any of these signs:
  • Hairline cracks
  • Mold and mildew
  • Discoloration or odors
  • Plumbing leaks
  • Uneven floors
  • Flooding
You should also know about the two different types of waterproofing. Interior waterproofing uses sump pumps, drains, and basement and crawlspace sealants. Exterior waterproofing, the less expensive option, involves exterior drains and physical barriers between your landscaping and foundation.

Will my homeowners insurance cover foundation repair?

Homeowners insurance generally doesn't cover foundation repair that results from normal settling, sinking, or wear and tear. However, you might have a claim if the damage was caused by a covered peril or disaster. Review your specific fire, earthquake, homeowners, and flood insurance policies and speak to your agency for exact information.

What are some "red flags" indicating a foundation company to avoid?

There are several signs that you should avoid a particular foundation provider. Watch out for inadequate credentials, poor online reviews, lack of insurance, high-pressure sales tactics, and unresponsiveness. Above all, trust your instincts, do your research, and get multiple estimates for the best possible decision-making power.
