Common Causes of Foundation Problems in San Francisco

A few factors can lead to foundation issues. Here are the most prevalent ones for San Francisco residents:

  • Aging plumbing: The average San Francisco home construction year is 1970. If you live in an older home, it's likely to have cast-iron plumbing. When the pipes start to erode, leakage could reach your foundation and even pool beneath it.
  • Standing water: Water accumulation around your home can be menacing to your foundation's integrity, especially when it collects in areas your gutters don't reach.
  • Improper modifications: Landscaping or roofing work that wasn't completed properly could lead to your foundation settling.
  • Tree Roots: Tree roots can enter a home's foundation through crevices, 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

Your home's integrity depends greatly on its foundation. It's vital to hire the best team possible. Focus your research on these 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 additional insight into a company's experience. You should ask about local inspection processes, permit ordinances and building codes.

Another way to measure a company's reputation is to examine its website. There, you can learn how long it's been in business and its trade qualifications. It might also share knowledge and insights through blog posts, podcasts, or videos.

Customer Reviews

We recommend reviewing the company's Better Business Bureau (BBB) profile to find out whether it's accredited and has a positive customer review score. You can see whether other homeowners have reported satisfaction or filed complaints. Pay special attention to what customers say about company warranties. Complaints aren't necessarily a red flag in themselves. You want to discover how a company handles them. If the management team consistently and proactively resolves issues, it's a good sign. However, if the company lacks accreditation, has more negative reviews, and doesn't communicate properly, you should avoid working with it.

Lastly, we encourage you to search other platforms, such as Trustpilot and Google, for more opinions.

Foundation Repair Cost in San Francisco

Foundation repair costs can vary substantially based on the scale of the problems and what needs to be done to fix them. For minor foundation cracking and settling issues, you may pay as little as $1,900. However, if there is considerable deterioration, the typical cost will be around $4,000. More complex jobs involving tunneling, helical piers, or extensive concrete leveling could run you $7,300. This table shows the average foundation repair costs for common issues.

Frequently Asked Questions About Foundation Repair in San Francisco

What will I pay to repair my foundation in San Francisco?

Foundation repair costs about $4,000 in San Francisco. The final numbers hinge on what type of repair you need and how severe the damage is.

When would I need a foundation replacement, and when could I just get a repair?

Most foundation issues don't require replacement to fix them. In uncommon cases, a foundation might require total restoration. However, if you pay attention to early warning signs like cracking walls or uneven doors, you probably won't need replacement.

What are the different types of foundations in San Francisco?

The top four foundation types in San Francisco are crawlspaces, pile-and-beam assemblies, slab foundations, and basements. The specific type your property has will depend on local temperatures, soil quality, and flood risk.

What are some signs I need foundation waterproofing?

You'll typically need to waterproof your foundation when you see any of these signs:
  • Mold and mildew
  • Hairline cracks
  • Uneven floors
  • Flooding
  • Discoloration or odors
  • Plumbing leaks
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.
