FL Whole-Home Repiping
PEX vs CPVC vs Copper — FL pricing, permits & material guide. Estimate includes labor, materials, and drywall patching allowance.
FL Repiping Price Reference
| Home Size | PEX | CPVC | Copper |
|---|---|---|---|
| Under 1,200 sq ft | $3,500–$6,500 | $3,200–$6,000 | $5,500–$10,000 |
| 1,200–2,000 sq ft | $5,000–$9,000 | $4,500–$8,500 | $8,500–$15,000 |
| 2,000–3,000 sq ft | $8,000–$14,000 | $7,500–$13,000 | $13,000–$22,000 |
| 3,000+ sq ft | $12,000–$22,000 | $11,000–$20,000 | $18,000–$35,000+ |
FL ranges include permit, drywall patch, and fixture reconnect. Slab homes add 15–25% due to tunneling complexity. South FL adds 10–20% for labor market. Copper premiums are higher due to current metal pricing.
FL Pipe Material Comparison
Florida's hard water, UV exposure, sandy soil, and high humidity make material selection critical.
PEX — Crosslinked Polyethylene (BEST FOR FL): Flexible enough to snake through slab without joints (fewer leak points); handles hard water without pitting/scale; freeze-resistant for rare FL cold snaps; quieter water hammer; fastest installation = lower labor cost. Hard water resistance Excellent; UV resistance Poor (needs protection); cost lowest; lifespan 50+ years. Cannot be exposed to UV (exterior); requires crimp or expansion fittings. PEX-A (Uponor/Wirsbo) preferred — most flexible; PEX-B acceptable; avoid PEX-C. All rated 180°F at 100 PSI.
CPVC — Chlorinated PVC (GOOD FOR FL): More rigid than PEX but chemically resistant to chlorinated municipal water; lower cost than copper; FL code compliant; common in homes built 1985–2010. Hard water resistance Very Good; UV resistance Poor (degrades); cost low-medium; lifespan 25–40 years. Brittle if frozen (rare in FL); more joints in slab = more leak risk; banned in some FL jurisdictions (check locally). Some FL insurers now prefer PEX over CPVC due to chemical sensitivity.
Copper (Type L) — PREMIUM, FL CHALLENGES: Historically the gold standard, but FL's hard water causes pinhole leaks within 8–15 years in high-mineral counties (South/Central FL). Much more expensive; still preferred by some insurers and required in some commercial codes. Hard water resistance Poor in high-hardness FL; UV resistance Excellent; cost highest; lifespan 8–20 years (hard water). Acceptable for outdoor/UV exposure; copper theft risk on vacant properties. Use Type L (not thinner Type M); water softener/whole-home filter strongly recommended.
FL Pipe Failure Timeline (Why You're Repiping)
- Galvanized Steel (pre-1970): replace immediately — heavy corrosion, flow restriction, orange/brown water, lead risk in solder joints.
- Polybutylene (1978–1995): gray plastic pipe — banned/recalled, catastrophic failure risk. FL insurers often refuse coverage; replacement is urgent.
- Copper (1970–2005): FL pinhole leak epidemic from hard water. Miami-Dade, Broward, Palm Beach, Hillsborough average 8–15 years before first leak. Now at/past end of life for most.
- CPVC (1985–2010): some FL installations developing brittleness and micro-cracks at 15–25 years; certain manufacturers had defects.
- PEX (2005–present): performing well; 50+ year expected lifespan. Monitor fittings at 15–20 years.
Permits are required for repiping in FL: all whole-home repiping requires a building permit; work must be performed by a licensed FL Certified Plumbing Contractor (CPC). Unpermitted work can void homeowner's insurance and create title issues at resale.
FL Repiping Permit Process
- Licensed FL CPC submits permit application to city/county building department with scope and pipe specs.
- Building department reviews and issues permit (1–5 business days; same-day in some counties for minor scopes).
- Plumber performs rough-in repipe — home water shutoff during this phase (1–3 days depending on size).
- Rough-in inspection: county inspector verifies pipe routing, supports, connections before walls close.
- Pressure test in inspector's presence: new lines tested at minimum 10 PSI for 15 minutes (or per local code).
- Inspector approves — drywall patching, texturing, painting can begin.
- Final inspection: all fixtures reconnected, water restored, no visible leaks.
- Permit closed — contractor provides permit documentation for your records and title disclosure.
FL County Permit Cost Guide
| County | Permit Fee Range | Timeline | Notes |
|---|---|---|---|
| Miami-Dade | $350–$750 | 3–7 days | HVHZ — extra requirements |
| Broward | $275–$600 | 2–5 days | Online permit system |
| Palm Beach | $250–$550 | 2–5 days | Wind zone considerations |
| Hillsborough | $200–$450 | 2–4 days | Tampa area standard |
| Pinellas | $175–$400 | 2–4 days | Clearwater/St. Pete |
| Orange | $200–$450 | 2–5 days | Orlando area |
| Duval | $150–$350 | 1–3 days | Jacksonville — faster |
| Lee | $175–$400 | 2–5 days | Fort Myers area |
| Sarasota | $150–$350 | 1–3 days | Streamlined process |
| Brevard | $150–$350 | 1–3 days | Space Coast |
| Other counties | $100–$300 | 1–3 days | Varies by municipality |
FL-Specific Repiping Considerations
- Pre-1978 FL Homes — Lead Paint Alert: federal law requires lead paint disclosure before repiping that disturbs walls; contractor must follow EPA RRP rules — ask for their EPA RRP certification.
- Slab foundation impact: most FL homes — adds 15–25% cost for tunneling or rerouting through attic.
- HOA approval: required if unit shares walls — submit permit + scope to HOA board first.
- FL water hardness: South FL 15–25 gpg (very hard); Central FL 8–15 gpg; North FL 4–10 gpg. Hard water accelerates copper pitting.
- Homeowner's insurance: many FL insurers offer premium discounts after repiping to PEX — ask your insurer.
- Water damage history: disclose prior pipe-related water damage claims — may affect coverage or pricing.
- Post-hurricane repiping: repiping triggered by storm damage may be covered under homeowner's policy — file claim first.
- Duration of water shutoff: plan for 1–3 days without water; contractor should provide portable toilet/water access plan.
- Drywall restoration: get written scope of what is vs. isn't included — patching, texturing, and painting often separate.
