• First known slab leak in a newer home (under 20 yrs copper)
• Single, precisely located leak point
• Budget-conscious repair (insurance paying for repair, not remediation)
• Tile pattern still available or owner accepts repair patch
• Pipe system otherwise in good condition
FL plumber reality: Most FL plumbers recommend against spot repair for homes with 30+ year copper under slab — another leak will likely appear within 1–3 years. Consider rerouting or repipe if home is pre-1990.
| Method | Cost | When to Use |
|---|---|---|
| Cut-out and patch | $400–$900 | Known location; single fitting failure |
| Camera + targeted patch | $600–$1,200 | Hidden leak; need locate first |
| Wall segment repipe | $1,200–$3,000 | Multiple points; galvanized pipe deterioration |
| Full floor repipe | $3,000–$8,000 | Whole floor of aging galvanized / CPVC |
| Drain Issue | Method | FL Cost Range |
|---|---|---|
| P-trap leak | Replace trap | $150–$300 |
| Cast iron failure | CIPP liner or replace | $2,500–$8,000 |
| Sewer line root intrusion | Hydro-jet + liner | $1,800–$5,000 |

Sudden and accidental discharge: FL homeowner policies generally cover sudden, accidental water damage from a plumbing failure — for example, a pipe that suddenly bursts and floods a room. This typically covers water damage remediation and drying.
What's usually excluded: Most FL policies exclude the cost of repairing or replacing the failed pipe itself (only the resulting damage). "Continuous or repeated leakage" is excluded — if an insurer determines you knew about a leak and didn't fix it, they may deny the claim entirely. Flood damage (from outside water) is excluded from standard HO — requires separate NFIP flood policy.
Citizens Insurance (FL's insurer of last resort) covers sudden water damage but is aggressively denying slow-leak claims. Citizens has implemented water leak coverage restrictions in recent years — review your specific policy carefully.
Assignment of Benefits (AOB): FL significantly restricted AOB in 2023 (SB 2-A). You now generally cannot sign over your insurance rights to a contractor before your insurer is notified. Work with your adjuster before committing to repairs for insurance claim purposes.
Slab leak coverage: FL policies vary widely. Some cover detection costs (breaking slab to find pipe) but not the pipe repair. "Ordinance or law" coverage in your policy matters when FL building code requires upgrading old pipes to current standards during repair — this upgrade cost may be covered.
FL mold risk timeline: FL's heat and humidity create ideal mold conditions. Mold can begin growing within 24–48 hours of water intrusion. After 72 hours, active mold growth is likely in wet drywall and insulation. After 1 week, mold remediation costs can exceed the original plumbing repair by 5–10×.
Mold remediation costs in FL: $15–$30/sq ft for affected area; average FL whole-room mold remediation: $3,000–$8,000; crawl space or attic mold from slow leak: $5,000–$15,000. FL mold coverage in standard HO policies is typically capped at $10,000 or excluded entirely — check your policy.
