Why repipe costs vary in Florida
- Slab vs. pier-and-beam foundation: FL slab homes (most common in South FL) require tunneling under slab for drain repipe — adds $2,000–$6,000. Pier-and-beam (more common in North FL) is easier to access.
- Number of bathrooms: Each additional bath adds $400–$800 in labor and materials.
- Two-story homes: Add 15–20%.
- FL permit required by law: Licensed plumbing contractor and permit required for whole-home repipes. Budget $300–$800 for permit. Do not waive — it protects you.
- Drywall restoration NOT included: Budget $1,500–$4,000 separately for patch/texture/paint.
- Timeline: Most single-story homes 2–4 days; two-story/complex slab 4–7 days.
Choosing the Right Pipe Material
FL's aggressive water chemistry makes material selection more important than in most states.
Supply Pipe Options
PEX-A (RECOMMENDED): Doesn't corrode in FL's aggressive water — the #1 reason copper fails in FL. PEX-A (Uponor/Wirsbo) is superior to PEX-B: better flexibility, connection security, easier through slab homes. Lifespan 25–50 years; 30–40% less than copper. Pros: corrosion-resistant, flexible for slab, freeze-resistant, quieter, lower cost. Cons: no outdoor/UV use, requires special expansion tool, not rigid.
Copper (FL CAUTION): Many FL plumbers now recommend against copper for supply due to pinhole leak history. FL's high chlorides and low pH aggressively attack copper. If chosen, request Type L (heavier wall). Best for short runs, high-heat, commercial. Pros: long history, excellent for hot water, rigid. Cons: pinhole leaks endemic in FL, highest cost, requires skilled soldering, vulnerable to FL water chemistry.
PEX-B (ACCEPTABLE): Adequate for most FL applications; crimp/clamp fittings vs. PEX-A expansion. Less flexible than PEX-A; for complex slab homes, PEX-A worth the premium. Solid mid-tier choice.
CPVC (ACCEPTABLE): Rigid chlorinated PVC, easier than copper, lower cost, long FL track record. Concern: more brittle than PEX — not ideal for North FL freeze risk or settling older homes.
Drain / DWV Pipe Options
Schedule 40 PVC (STANDARD): Overwhelming standard for FL drain replacements. Durable, chemical-resistant, low cost. For cast iron replacement, 3" and 4" Sch 40 PVC is the go-to. Lifespan 50–70+ years. Ask about sound insulation wrap near bedrooms.
ABS (ACCEPTABLE): Less common but acceptable — more flexible, easier to cut. Not compatible with CPVC cement — verify before mixing materials.
Florida Building Code Requirements
Licensed Plumbing Contractor required under FL FS 489 (verify at myfloridalicense.com). Permit required by law per FBC Plumbing 2020. All new pipes must be accessible for inspection before walls/floors are closed. Post-installation pressure test is mandatory.
What to Ask Your Repipe Contractor
- Are you licensed as a FL Master Plumber or Plumbing Contractor under FS 489?
- Do you pull the permit? (Answer should always be: we pull it.)
- Is the price fixed-price or time-and-materials? (Fixed strongly preferred.)
- Does the quote include drywall patching, or is that separate?
- What pipe brand? (Uponor/Wirsbo for PEX-A; Nibco or Charlotte for PVC.)
- Warranty on both labor and materials? (Min 1 year labor; pipe manufacturer warranty transfers.)
- Will you perform a pressure test with written documentation?
- Is financing available? (GreenSky, Synchrony, HFS Financial.)
Signs It's Time to Repipe
- Low water pressure throughout the house (not just one fixture)
- Discolored water — brown, orange, or rust-colored when first turned on
- Multiple pinhole leaks or leaks at pipe joints
- Water stains or mold on walls/ceilings without known source
- Older home (pre-1985) and pipes never replaced
- Slow drains throughout — snaking hasn't helped long-term
- Sulfur smell or metallic taste
- Pressure fluctuates when multiple fixtures run
- Polybutylene (gray or blue plastic) supply pipes
What to Expect During a FL Repipe
- Day 1 — Demo/Open Access Points: Contractor opens walls/ceilings/slab access, removes old pipes. Water off most of the day; restored each evening.
- Day 2–3 — New Pipe Installation: New lines run through walls, ceilings, under slab. PEX flexibility speeds this vs. copper.
- Day 3–4 — Connections: New lines connected to all fixtures, water heater, shutoff valves. Bathroom count matters most here.
- Day 4 — Pressure Test & Inspection: Pass/fail test with documentation; city/county inspector visits. This is the permit inspection — do not skip.
- Day 5+ — Closeout/Drywall Patching: Often a separate drywall contractor; budget $1,500–$4,000.
Minimizing disruption: Most homeowners stay in their home (water restored each evening). Hotels rarely needed. Plan for 2–5 days partial disruption; have bottled water for day 1.
FL Homeowners Insurance & Repiping
Some FL policies cover pipe replacement under 'service line coverage' or when tied to a covered water damage claim. Polybutylene replacement may be partially covered if you've had prior burst pipe claims. Contact your insurer before starting; a licensed plumber's written assessment is your strongest basis for a coverage conversation.
Florida Permit Warning
A repipe permit protects you — it ensures the work is inspected and documented. If a contractor asks you to waive the permit 'to save money,' walk away. An unpermitted repipe voids homeowner's insurance for related claims and creates serious problems when you sell.
(Polybutylene note: gray/blue pipes fail without warning; a burst supply line can cause $20,000–$50,000 in water damage.)
