Three foundation bids, a $10,000 spread, and no one showed you the math.
Settling does not wait for you to decide. Neither does the next bid revision. We measure the movement, tell you whether it is piers, foam, or nothing yet, and put the number in writing before any work is scheduled.
“The added-on room is pulling away from the house, probably because the roots from a tree we removed finally rotted out and left a void under the slab.” — r/HomeImprovement
- Fixed-price written quote before any work starts. The number on the estimate is the number on the invoice, or the difference is ours.
- Zero-obligation on-site inspection. If the answer is 'monitor it, do not spend money yet,' that is the answer you get in writing.
- Licensed, bonded, and insured, with the license number on the estimate itself, not just the truck.
- Itemized scope: every line shows what is being done, what it costs, and what it does not include. No lump-sum 'foundation work, $18,000.'
- Named point of contact with a same-day callback commitment. If we go quiet for 48 hours during an active job, the next scheduled payment is waived.
- Written start and completion window, with the permit and utility dependencies listed as separate line items so you can see which clocks we do not control.
- If a second opinion contradicts our diagnosis on a structural call, we pay for a third-party engineer's evaluation.

Why Homeowners Start Here
Why Foundation Underpinning in San Diego Beats a Wait-and-See Approach
San Diego County sits on a difficult mix for foundations: expansive coastal clays that swell and shrink with the wet season, decades of engineered fill on canyon-edge lots, and hillside grading that concentrates runoff exactly where you don't want it. Settlement here tends to accelerate rather than stabilize. We route your project once to a CSLB-licensed foundation contractor suited to your soil condition, scope, and permit jurisdiction.
- CSLB-licensed foundation contractors only
- Projects requiring a licensed engineer's stamp are matched accordingly
- No cost, no obligation to the homeowner
Warning Signs Worth a Call
- Stair-step cracking in stucco, block, or brick
- Doors and windows sticking on one side of the house
- Sloping or bouncing floors, separating baseboards
- Patio or walkway pulling away from the house
- Soil cracks, bulging, or leaning fences near a canyon edge
Good to Know
Frequently Asked Questions
Is this service really free?
Yes. There is never a cost to submit a request or be matched. We may receive a referral fee from the contractor, which never affects your quoted price.
Are the contractors licensed?
We work only with independent contractors holding active CSLB licenses appropriate to foundation work. Always verify a license directly at cslb.ca.gov before signing a contract.
Do I need an engineer as well as a contractor?
Most underpinning permits in San Diego County require calculations stamped by a California-licensed civil or structural engineer. See our cost and permitting page.
I'm in escrow — can this move fast enough?
Flag the escrow timeline on your request. Bids move quickly; permits and engineering are the long pole. Read the escrow inspection guidance.
