Foundation repair in San Diego. We diagnose first, fix second.
Cracked drywall, sloped floors, sticking doors, gaps at the baseboard: those are symptoms, not the problem. The problem is almost always the soil under your house. We start every job with a level survey and an engineer-stamped diagnosis, then build a repair plan that matches the actual movement, not a guess. No scare tactics. No upsell to piers you don't need.

What do homeowners ask about Foundation Repair?
How much does foundation repair cost in San Diego?
Crack injection runs $400 to $1,200 per crack depending on length and width. Helical or push pier underpinning runs $1,800 to $3,500 per pier installed, with most settled corners needing 4 to 8 piers. A typical full repair on a 1,800 sq ft home runs $12,000 to $35,000. We give you a flat-rate written quote after the inspection. No hourly billing, no surprise change orders.
Will my homeowner's insurance cover this?
Usually not. Standard policies exclude settlement, soil movement, and 'earth movement' even when the cause is plumbing leak related. The exception is sudden damage from a covered peril (a vehicle hits the home, a tree falls, a water-main break under the slab). We document the cause carefully so if there is a coverable angle, your adjuster has what they need.
Do I really need an engineer?
For anything beyond a single crack, yes. The City of San Diego and most San Diego County jurisdictions require a stamped repair plan for pier installation and major structural work. We work with several local structural engineers and coordinate the inspection, plan, and permit so you do not have to chase three vendors.
How long does a repair last?
Helical and push piers are warranted for the life of the structure when installed by manufacturer-trained crews. Crack injection is warranted 5 to 10 years depending on the product. We give written transferable warranties on every job.
Can you tell if my foundation is moving right now?
Yes. We install crack-monitor gauges and re-survey at 60 and 90 days. If a crack is widening more than 1/32 inch per month, the movement is active and we recommend repair. If readings are flat across two seasons, the foundation has likely stabilized and you may only need cosmetic repair.

Cracks at our window corners had me convinced we needed major repairs. Their inspector did the level survey, mapped every crack, and told us straight up the foundation was stable old movement and we did not need underpinning. Free inspection, honest answer, no pressure.
Got three quotes for foundation work. Two pushed full perimeter underpinning, Base Pro recommended four piers at the settled corner only and saved us $18,000. Engineer signed off, permit pulled, work was clean. House is solid two years later.
Active leak through a foundation crack after the January storm. They came out, identified it as a non-structural water issue, injected hydrophobic polyurethane, and pointed out that our downspout above the crack needed an extension. Both fixes done in one visit, leak gone.
