The early warning signs
of a foundation problem
Foundation issues rarely announce themselves. They show up as small annoyances first. Tap what you’re seeing — we’ll know exactly what to look for.
Cracks in Walls
Diagonal cracks from door and window corners, or stair-step cracks in brick and stucco.
Sticking Doors & Windows
Doors and windows that bind, won't latch, or have opened gaps at the corners.
Sloping or Bouncy Floors
Floors that dip, slope, or feel “off” — common where old post-and-pier has settled.
Wet or Musty Crawl Space
Standing water, damp soil, or musty odors driving rot, mold, and poor air upstairs.
Uneven Concrete
Sunken driveways, patios, and walkways that trip you up and pool water.
Bowing or Leaning Walls
Foundation walls pushing inward from soil pressure or hydrostatic load.
Why Choose Stronghold
Northern California's Trusted
Foundation Repair Specialists
When your home needs foundation repair, crawl space work, or structural reinforcement, experience matters. For 12+ years Stronghold has served Sacramento, the Bay Area, and the Central Valley — fixing foundations the right way, with a third-party engineer's plan before a single pier goes in.
Independent Structural Engineering
Not our engineer — a licensed third-party structural engineer designs every foundation repair job. Very few NorCal competitors require this on residential work.
Life-of-Structure Foundation Warranty
Our foundation repair warranty stays with the home even after you sell. Backed by a ~$16M national trust across 64 franchises.
100% American-Made Steel
Raw steel from Pittsburgh, PA — fabricated in Ada, OK. A fully domestic supply chain for every pier and bracket we install, not "assembled in USA" with imported parts.
Family-Owned, NorCal-Rooted
The owners pick up the phone, know every crew member, and show up on foundation repair jobs. 12+ years solving Sacramento clay and Bay Area hillside problems.
No Commissioned Sales
Our foundation inspectors are not paid on commission. The repair plan you receive is what your home actually needs — not what writes the biggest invoice.

Foundation Repair Reviews
What Northern California Homeowners Say
About Our Foundation Repair Work
★★★★★
“Stronghold found an issue with our pier caps that three other foundation repair contractors missed entirely. The crew was fast, left the site cleaner than they found it, and the repair has held for 18 months. Best home investment we've made.”
★★★★★
“I was skeptical about foundation work but the independent engineering report made all the difference. No salesperson pressure, just facts and a written estimate. Foundation repair was done in two days.”
★★★★★
“Drainage was washing out our back corner for years. Stronghold re-graded the yard and installed a French drain in one visit. No more standing water and the foundation crack hasn't moved since.”

Common Questions
Foundation Repair
Questions, Answered
Not sure what to expect? Here are the questions we hear most from Northern California homeowners.
How do I know if my foundation needs repair?
The most common warning signs include cracks in drywall or brick, doors and windows that stick or no longer close properly, sloping or bouncy floors, gaps between walls and ceilings, and visible cracks in your concrete foundation. If you notice any of these, a free inspection will tell you exactly what's happening.
How long does foundation repair take?
Most residential foundation repairs are completed in one to three days. Helical and push pier installs typically take one to two days depending on the number of piers required. Crawl space work, drainage systems, and larger projects may take two to five days. We give you a firm timeline before work begins.
Do you require a third-party structural engineer?
Yes — and that's intentional. A licensed structural engineer (not our engineer) designs every foundation repair plan before a single pier goes in. Very few Northern California contractors require this on residential work. It protects you from over-selling and ensures the repair is sized correctly.
Will foundation repair affect my home's resale value?
Done correctly, foundation repair protects and often increases your home's value. Our life-of-structure warranty transfers to the new owner at closing, which is a strong selling point. Buyers' inspectors flag unrepaired foundation issues — a completed repair with a transferable warranty removes that objection entirely.
Is foundation repair covered by homeowner's insurance?
Most standard homeowner policies do not cover settlement or soil-related foundation damage, but some do cover sudden structural damage caused by a covered peril (like a burst pipe). We recommend contacting your insurer before your inspection. We can provide detailed documentation to support a claim if coverage applies.
What is the difference between helical piers and push piers?
Push piers are hydraulically driven through the foundation footing into load-bearing strata — ideal for heavier structures and active settlement. Helical piers are screwed into the soil like a large bolt and work well in softer soils or where access is limited. Our structural engineer specifies the right system for each job.

03
Written, No-Pressure Estimate
Clear, itemized, no obligation. No commissioned salespeople, no upsell — just the work your home actually needs.
04
