LA Water Damage Timeline — What Happens in the First 72 Hours
In LA water losses, what you do in the first 72 hours determines whether you're paying for drying ($3–$12/sqft) or mold remediation ($1,500–$15,000+). This is the hour-by-hour playbook.
Hour 0–24: Emergency response
Stop the water source. Main shutoff valve, turn off affected circuits if wet electrical is present.
Call a licensed restoration GC (not just a mitigation-only firm) — 2-hour response target from anyone reputable in LA.
Water extraction with industrial pumps.
Emergency shoring if structure is compromised.
Initial moisture mapping with thermal imaging + pin/pinless meters.
Board-up and tarping as needed.
Document everything: photos, video, moisture readings. Insurance cases are won or lost on documentation.
Day 1–7: Structural drying (IICRC S500 protocol)
Industrial dehumidifiers + air movers sized to the affected area.
Daily moisture monitoring until all readings meet targets (typically 15–17% moisture content for structural wood).
Antimicrobial treatment on affected surfaces.
Removal of unsalvageable materials (wet carpet pad, saturated drywall, wet insulation).
Cost: Category 1 clean water $3–$4.25/sqft; Category 2 gray water $4–$6.50/sqft; Category 3 sewage/black water $7–$12/sqft.
The 24–48 hour mold activation window
Mold spores activate at 24–48 hours of sustained moisture.
Colonization begins by 72 hours.
After 72 hours of standing water, Category 3 protocols automatically apply regardless of original water source.
California SB 655 defines visible mold as a substandard building condition — legal and liability implications compound over time.
Insurance claim sequence
File initial claim within 24 hours. Carrier assigns an adjuster, typically 24–72 hours to first site visit.
Adjuster walks the site. Good GCs coordinate this visit and bring independent documentation.
Initial settlement offer — often low. Expect to supplement.
30-day supplement window — this is where well-documented GCs recover 20–40% more.
Final release — sign only after you're confident the scope is complete.
Pre-1994 plumbing trigger
Any plumbing permit on a pre-1994 home triggers whole-house low-flow fixture replacement to current water-efficiency standards.
Adds $3,000–$8,000 to any plumbing-related repair on older LA homes.
Discovered mid-project is painful. Plan for it upfront.

LA Water Damage Timeline — scoped by Baily.
Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon's rim.
He wasn't the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily's contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily's beads.
That's what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner's real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That's our vibe too.
