Common Causes of Foundation Problems in Diamond Bar

A home in Diamond Bar might experience foundation issues for multiple reasons. Some are unique to the local environment, while others are prevalent nationwide. They include:

  • Standing water: Water accumulation around your home can harm your foundation, especially when it gathers in areas your gutter system doesn't reach.
  • Improper modifications: Roofing or landscaping work that wasn't performed properly could result in your foundation settling.
  • Aging plumbing: The average Diamond Bar home construction year is 1980. If you live in an older home, it's likely to have cast-iron plumbing. When the pipes start eroding, leakage could reach your foundation and even pool beneath it.
  • Tree Roots: Tree roots can enter a home's foundation through crevices, and may exert pressure that causes your foundation cracking, pipes being damaged, and overall structural destabilization.

How to Choose the Best Foundation Repair Company

Your home's integrity weighs heavily on its foundation. It's crucial to hire the most qualified crew possible. Focus your research on these characteristics:

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. You can also get a sense of a company's experience through the details its representatives share. Ask about its inspection methods, local code requirements, permit-pulling procedures, and fees.

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

Customer Reviews

Before selecting a company, check its online profile with the Better Business Bureau (BBB). You can examine both complaints and positive reviews. Complaints aren't necessarily a red flag in themselves. You want to discover how a company manages them. If the management team proactively and consistently resolves issues, it's a good sign. However, if the company lacks accreditation, has more negative reviews, and doesn't communicate properly, you should think twice about working with it.

Lastly, we recommend you search additional sites, such as Trustpilot and Google, for other reviews.

Foundation Repair Cost in Diamond Bar

The price of your foundation repair project can vary substantially based on the extent of the issues and what needs to be fixed. For minor foundation fracturing and settling problems, you may pay as little as $1,800. However, if there is substantial deterioration, the average cost is about $2,700. More complex projects requiring tunneling, helical piers, or major mudjacking could cost $6,800+. This table shows the average foundation repair costs for common issues.

What preventive measures can I take to avoid foundation issues?

You can take several preventive measures to prevent foundation issues:
  • Ensure your home's gutters and downspouts are in good condition and direct water away from your foundation to prevent water accumulation.
  • Irrigate the soil around your foundation evenly, especially during dry spells, to prevent shrinking and expansion.
  • If possible, grade the soil around your home to angle away from your foundation, promoting water drainage and minimizing the risk of foundation issues.
  • Keep an eye on your foundation for cracks, and fix any issues immediately.
