Water damage is a silent budget-killer. HomeAdvisor’s 2025 survey puts the national average restoration bill at $3,824, with common ranges from $1,362 to $6,286.
In Los Angeles, where labor and construction prices run hotter, the average lands around $3,160, but invoices can climb past $17 K when structural framing is wet.
Direct dollars you’ll feel immediately
- Flooring replacement – hardwood or luxury-vinyl planks: $6–9 per sq ft installed.
- Drywall tear-out & reinstall – $1.50–$3 per sq ft, plus finishing.
- Sub-floor or joist repairs – $15 K+ once moisture reaches structural lumber.
Hidden expenses nobody warns you about
- Energy spikes. Damp insulation loses R-value, forcing HVAC systems to run longer.
- Mold remediation. Spores can colonize damp sheetrock in as little as 24–48 hours. Professional removal often doubles the original bill.
- Financing delays. Mortgage lenders may withhold draws on home-equity projects until moisture tests clear.
- Insurance deductibles. One large claim can boost premiums 15–20 % at renewal.
Why small leaks become six-figure headaches
A slow supply-line drip keeps wood at 17 % moisture—perfect for decay fungi. Over months that can trigger sill-plate rot, termite activity, and foundation settlement. By the time the leak surfaces, repair crews may have to sister joists, jack walls, and pour new piers.
Five proactive moves that cost less than $200 each
- Swap rubber washing-machine hoses for braided stainless steel.
- Install $40 leak-sensing shut-off valves beneath sinks.
- Flush the water heater annually to avoid tank rupture.
- Slope soil so rain flows away from the slab.
- Photograph every room today—clean “before” pics speed future insurance claims.
