Our Foundation Repair Process

01

Structural Assessment

A foundation specialist inspects all cracks, settlement patterns, drainage conditions, and soil conditions to develop a repair plan.

02

Engineering Review

For significant work, a structural engineer reviews and stamps the repair design.

03

Repair Installation

Steel push piers or helical piers are installed to bedrock or load-bearing soil; wall anchors or carbon fiber straps address bowing walls.

04

Lift & Verification

Where possible, the foundation is lifted back toward original grade. All work is verified with measurements before completion.

Foundation Repair FAQ for San Francisco Homeowners

How often should San Francisco homeowners get foundation repair?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from foundation repair at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need foundation repair?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
Are all foundation cracks serious?
Not all cracks are structural. Hairline cracks in block or poured walls from normal curing are common. Horizontal cracks in block walls, stair-step cracks, and cracks over 1/4 inch wide are more serious and warrant professional evaluation.
How do I know if my foundation is failing?
Warning signs: doors and windows that stick or won't close, sloping floors, diagonal cracks from window corners, cracks wider than 1/4 inch, and horizontal cracks in basement walls.
Can a foundation be repaired or does it need to be replaced?
Foundation repair — not replacement — is almost always the solution. Replacement is extremely rare and prohibitively expensive. Piers, anchors, and drainage correction resolve the vast majority of issues.
Do I need to disclose foundation repairs when selling?
Yes. Known foundation issues and past repairs must be disclosed in most states. A repaired foundation with a transferable warranty is often less concerning to buyers than an untouched failing foundation.
