Learn moreWhy do San Diego homeowners choose Base Pro San Diego?
San Diego County soils are not generic. Expansive clays in Escondido and Vista, alluvial fill in South Bay, decomposed granite in East County, hillside slope creep on coastal bluffs. Each one needs a different answer. We diagnose first, then build the repair plan to match the actual movement.
- Diagnosis before recommendation. Level survey, crack mapping, soil indicators. We tell you what the foundation is doing before we tell you what to do about it.
- Engineer-stamped repair plans. Every pier and underpinning job carries a structural engineer's stamp. Permit, plan, and inspection coordinated end-to-end.
- Flat-rate written quotes. You see the full price before we start. No hourly billing, no surprise change orders, no scare tactics.
- Lifetime-of-structure warranty. Helical and push piers warranted for the life of the building. Crack injection 5 to 10 years. Transferable on sale.

What homeowners across the county say
Examples of the kind of feedback we work to earn on every job. Verified reviews from real customers live on our Google Business Profile and Yelp pages.
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.
Plumbing leak under our slab created a void and a low spot in the kitchen. They coordinated with our plumber, filled the void with polyurethane, lifted the slab back to level, and the tile is sitting flat again. Reasonable price, no surprises on the invoice.
Pre-purchase inspection on a 1970s home. Their written report was detailed, photo-documented, and gave us real ammunition to negotiate $22,000 off the price for repairs. Inspection paid for itself many times over.
Bluff-side home with chronic stem-wall moisture. They designed an exterior waterproofing system with proper drainage, replaced the silted-up perimeter drain, and the crawl space has been bone dry through two winters. The original installer would have said sump pump; they said daylight discharge. They were right.

All FAQsWhat areas in San Diego County do you service?
Every city in San Diego County, all 47 of them. Coastal homes from Imperial Beach to Oceanside, inland from El Cajon to Escondido, mountain communities from Julian to Pine Valley. If your foundation is in the county, we get there.
How fast can you inspect my foundation?
Most inspections book within 3 to 5 business days. Active settlement, post-storm damage, or pre-listing deadlines can usually be slotted faster. The free repair-quote inspection is 60 to 90 minutes onsite.
How much does foundation repair cost?
Most full foundation repair jobs fall in the $12,000 to $35,000 range for a typical single-family home. Crack injection runs $400 to $1,200 per crack. Helical or push piers run $1,800 to $3,500 per pier installed. We give a flat-rate written quote after the free inspection.
Will my homeowner's insurance cover this?
Usually not. Standard policies in California exclude soil movement and settlement, even when caused by plumbing leaks. The exception is sudden damage from a covered peril (vehicle impact, fallen tree, water main break under the slab). We document the cause carefully so if there's a coverable angle, your adjuster has what they need.
Do I need a structural 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 coordinate the engineer, plan, and permit so you don't chase three vendors.
