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 Sunnyvale

Foundation issues have multiple possible causes. Here are the top ones for Sunnyvale residents:

  • Standing water: Water accumulation around your home can be a menace to your foundation, especially when it gathers in areas your drainage system doesn't protect.
  • Aging plumbing: The average Sunnyvale home construction year is 1976. 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.
  • Improper modifications: Roofing or landscaping work that wasn't done properly could result in your foundation settling.
  • Tree Roots: Tree roots can enter a home's foundation through crevices, and may apply force that leads to your foundation fracturing, pipes being damaged, and overall structural destabilization.

How to Choose the Best Foundation Repair Company

To select a foundation repair contractor, you should determine what's most important to you. Use this list of attributes to help you navigate the process.

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 inspection processes, permit ordinances and building codes.

Another way to evaluate a company's credibility 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

Before choosing a company, examine its online profile with the Better Business Bureau (BBB). You can examine both positive reviews and complaints. Complaints don't mean a contractor is unreliable. BBB reviews show how the company handled complaints. It's a positive sign if the company has resolved issues favorably and proactively. You should stay away from a company with numerous negative reviews, no accreditation, and no communication regarding issues.

Foundation Repair Cost in Sunnyvale

The cost of foundation repair can vary quite a bit depending on the extent of the issues and what needs to be done to resolve them. For minor foundation fractures and settling issues, you may pay as little as $1,900. However, if there is considerable damage, the average cost will likely fall around $3,300. More complex jobs involving excavation, helical piers, or concrete leveling could cost $7,000 or more. See below the average foundation repair costs for common issues.

Common Foundation Repair Services Average Cost
Crack Repair $382
Leak Repair $3,120
Stabilization $5,443
Underpinning $1,462
Waterproofing $3,452

Frequently Asked Questions About Foundation Repair in Sunnyvale

How much does foundation repair cost in Sunnyvale?

You could spend about $3,300 on materials and labor for your foundation project. Ultimately, your costs will depend on your specific needs and the extent of the damage.

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 unique 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 a new foundation.

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

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

Will foundation repair disrupt my daily routine while the work's being done?

You don't need to leave your home for foundation repair. Today's technology allows exceptional results with reduced disruption and digging. However, the crew will still use heavy machinery, and you may still hear loud noises and feel vibration while they're working. If these would annoy you, you can always choose to leave and return when the crew is finished.
