This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Causes of Foundation Problems in Napa

A few typical reasons why Napa homeowners experience foundation troubles include:

  • Aging plumbing: The average Napa home construction year is 1970. If you live in an older home, it's likely to have cast-iron plumbing. When the pipes start eroding, leaking water could reach your foundation and even pool beneath it.
  • Drought conditions: Napa is susceptible to drought. The shortage of rainfall and fluctuating humidity levels each season result to ever-shifting soil. The resulting soil settlement can shift and damage your foundation.
  • Improper modifications: Roofing or landscaping work that wasn't performed properly could lead to your foundation settling.
  • Standing water: Pooling water around your home can threaten your foundation, especially when it gathers in areas your drainage system doesn't cover.
  • Tree Roots: Tree roots can enter a home's foundation through cracks, and may apply force that leads to your foundation breaking, pipes being damaged, and overall structural destabilization.

How to Choose the Best Foundation Repair Company

When choosing a foundation repair company, you should consider your personal priorities. Ask each company on your list about the following qualities.

Licensing and Experience

The Golden State issues many different kinds of contracting licenses, and foundation companies often have more than one. You can verify a company's licensing information through the Contractors State License Board, a division of the California Department of Consumer Affairs. Look for a company with a General Building Contractor, General Engineering Contractor, C-8 Concrete, or C-61 Pile Driving credential. Talk to representatives to gain further insight into a company's experience. You should ask about local permit ordinances, building codes and inspection processes.

One of the most effective ways to assess a company's reputation is to visit its website. Look for the company's history 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, visit 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. Negative feedback doesn't mean a contractor is unreliable. BBB reviews show how the company handled complaints. It's a positive sign if the company has settled issues appropriately and proactively. You should stay away from a company with many negative reviews, no certifications, and no communication regarding issues.

Foundation Repair Cost in Napa

The price of foundation repair can vary substantially depending on the extent of the issues and what's required to resolve them. For minor foundation cracking and settling concerns, you may pay as little as $1,800. However, if there is considerable deterioration, the normal cost lands at about $2,900. More complex projects involving digging, helical piers, or major mudjacking could cost upwards of $6,900. Below are the average foundation repair costs for common issues.
