FREQUENTLY ASKED QUESTIONS

How much does a seismic retrofit cost in Los Angeles?

Cost depends on the size of the house, the foundation type and access under the floor. We scope it after an engineer's assessment so the number reflects the actual work, not a guess.

Can you remove a load-bearing wall?

Yes, with engineering. A structural engineer specifies the beam and posts, the plans go through plan check, and the work is inspected. Removing a load-bearing wall without a permit is a serious problem at resale.

Do you work on hillside properties?

Yes. Hillside work in LA involves soils reports, caissons or grade beams, and a more involved plan-check process, all of which we coordinate.

Do you offer foundation repair near me in the greater LA area?

Yes. Our foundation repair, seismic retrofit and structural framing crews work across Los Angeles County and neighboring counties within roughly 100 miles of our Woodland Hills office, including hillside communities from Glendale to Malibu.
