Earthquake Retrofit Foundation Services in San Diego & Orange County

Is your foundation prepared for an earthquake in Southern California?

If you own an older home in SoCal with a raised or crawlspace foundation, that question matters more than most people realize. Older houses may not be properly anchored to the foundation, making them more vulnerable to shaking and more likely to slide off their foundation during a quake.

We help homeowners in San Diego & Orange Counties install earthquake-specialty-designed plates.

Why Earthquake Retrofit your home?

Southern California is situated on active fault lines, and many homes with raised foundations were built long before modern seismic standards were established.

Over time, soil movement, moisture, and aging materials can weaken posts, piers, beams, and stem walls. When shaking hits, those weak points can translate into shifting, cracking, or separation that’s costly to fix and disruptive to live through.

If you’re in older neighborhoods across Southern California, such as La Jolla, Oceanside, Mission Hills, Mission Viejo, Tustin, Costa Mesa, North Park, La Mesa, or Huntington Beach, there’s a strong chance your home has the exact foundation style that benefits most from a proactive seismic upgrade.

Access to structural engineers is available for projects that need it.

Upgrade your home to be more seismic and earthquake resistant

We specialize in earthquake and seismic retrofitting for raised foundation, crawl space, and post & pier homes across both counties.

  • Posts and piers
  • Beams and floor systems
  • Stem walls
  • Crawl-space conditions and moisture impacts

If we find vulnerabilities, we focus on practical reinforcement and seismic retrofitting instead of pushing a full replacement. That keeps your project more affordable and far less invasive.

If your crawl space is showing moisture damage or structural wear, our crawl space foundation repair work often pairs naturally with earthquake and seismic retrofitting.

For projects that require it, we have structural engineers available.

Why This Matters More Than You Think

Most homeowners don’t worry about their foundation until something looks or feels off or there are clear signs of foundation issues. But earthquake risk flips that logic. The real danger is what you can’t see.

A raised foundation that isn’t properly secured can shift during a quake and create a chain reaction: uneven floors, cracked walls, jammed doors, and damage that spreads fast. After the 1994 Northridge Earthquake, many homeowners learned the hard way how vulnerable older raised systems can be under strong shaking.

The cost of prevention is predictable. The cost of waiting isn’t.

Frequently Asked Questions

Why are raised foundations in San Diego and Orange County especially vulnerable to earthquakes?

Many homes here were built before modern seismic standards. Raised foundations can shift, crack, or even fail during a quake if posts, piers, and stem walls aren’t properly supported. Repairing and securing these components helps make homes more earthquake-resistant.

What signs should homeowners in SoCal look for that may indicate foundation problems?

Look for sloping floors, sticking doors, cracks above openings, sagging floors, bulging stucco, or gaps near the chimney. These problems are common in older coastal and historic neighborhoods due to age and soil movement. 

Do earthquake repairs mean replacing my entire foundation?

No. Most homes don’t need full replacement. We focus on repairing and retrofitting and securing the existing raised foundation, which is more affordable and less invasive. 

How long do raised foundation repairs usually take?

Most projects take 1-3 days, depending on damage and crawl-space accessibility. Older homes in tight crawl spaces may take a bit longer. 

What causes foundation issues besides earthquakes?

Soil expansion, flooding, moisture changes, poor drainage, age, winds (especially Santa Ana winds) and coastal humidity can all impact raised foundations. Areas with clay soil often experience movement that leads to uneven floors and stem-wall cracking.
