1,500–2,000 sq ft	$4,500–$8,000	$9,500–$15,000	$5,500–$9,500
2,000–2,500 sq ft	$5,500–$10,000	$12,000–$19,000	$7,000–$12,000
2,500–3,000 sq ft	$7,000–$13,000	$15,000–$23,000	$9,000–$15,000
3,000+ sq ft	$9,000–$16,000	$18,000–$28,000	$11,000–$18,000

Slab premium: FL concrete slab homes add 40–120% to the above estimates due to jackhammering, concrete cutting, and floor restoration. Most FL homes are on slab.

🔵 PEX (Cross-Linked Polyethylene) — Best for FL Slabs

PEX-A (Most Flexible — Uponor, Rehau) $2–$4.50/ft installed

Best choice for FL slab homes. Maximum flexibility means fewer fittings and less jackhammering — pipes can be routed through walls and under slabs with small access holes. 25-year warranty, resistant to freezing. PEX-A expands and recovers, making it the most reliable variant.

Slab-friendly Freeze-resistant Lowest total cost Chloramine-safe UV-sensitive (must be covered)

PEX-B (Stiffer — Viega, Watts) $1.80–$4.00/ft installed

Slightly stiffer than PEX-A but still flexible. Uses crimp or clamp fittings. Widely available. Good choice for FL homes where cost is primary concern. Slightly less flexible — may require more access points in complex slab routing.

Wide availability Cost-effective Less flexible than PEX-A

FL recommendation: PEX is the preferred material for Florida slab homes. Its flexibility drastically reduces concrete cutting and jackhammering costs — often the difference between a $6,000 and $12,000 repipe job.

🟤 Type L Copper — Traditional Choice

Type L Copper (Standard Wall) $4.50–$9.00/ft installed

The traditional standard for FL plumbing. Proven 50–70 year lifespan when water chemistry is compatible. Fully recyclable, no plastic off-gassing concerns. Still preferred for high-end construction and by homeowners who want the "gold standard" material.

50–70 yr lifespan Recyclable value Proven track record Expensive Pinhole risk in acidic water

FL copper pinhole epidemic: Miami-Dade, Broward, and Tampa Bay water utilities add chloramine (not plain chlorine), which is more aggressive toward copper than chlorine. Copper pipes in chloramine service areas can develop pinhole leaks in 15–25 years — significantly shorter than the 50–70 year lifespan in non-chloramine water. A water softener does not prevent chloramine pitting.

Chloramine utilities in FL: Miami-Dade Water, Broward County Water, Tampa Bay Water, Hillsborough County, Palm Beach County Utilities. If your utility uses chloramine and you want copper, ask about Type K (thicker wall) as a premium option.

⚪ CPVC — Caution in FL Chloramine Areas

CPVC (Chlorinated PVC) $2.50–$5.00/ft installed

Mid-range option. Cheaper than copper, easier to work with than PEX in some configurations. However, CPVC has a documented degradation issue in FL: chloramine in utility water attacks the plasticizers in CPVC, causing it to become brittle and crack — often within 10–15 years in chloramine service areas.

Intermediate cost Easy to install Chloramine degradation risk Brittle with age Avoid in South FL/Tampa

FL CPVC warning: If your utility uses chloramine (Miami-Dade, Broward, Tampa area, Palm Beach County), CPVC is not recommended. Class action lawsuits have been filed against CPVC manufacturers in FL. Plumbers in these counties now typically refuse to install CPVC in residential settings.

🚨 FL Problem Pipes — Do You Have These?

POLY-B

Polybutylene (gray or blue, 1978–1995) — Must replace immediately. Polybutylene (Quest, Vanguard, Shell) was installed in millions of FL homes and mobile homes. Class action settlement (Cox v. Shell) funded replacements but the fund is exhausted. These pipes fail suddenly — catastrophic leaks with no warning. Very common in FL homes built 1978–1995. Identified by: gray or blue plastic pipe, stamped "PB2110" or "Quest." Often found at the water meter connection and under sinks.

GALV.

Galvanized Steel (pre-1970) — Replace when symptoms appear. Zinc coating corrodes from inside out in FL's mineral-rich water. Signs: rust-colored water, severely reduced pressure, brown staining on fixtures. Common in pre-1960s FL homes. Often found in the supply lines while drain pipes are separate cast iron. Identified by: gray/silver metallic pipe that shows rust streaks at joints. Threaded fittings, often with white mineral buildup at joints.

LEAD

Lead Pipe / Lead Solder (pre-1986) — Health hazard, replace immediately. Lead pipes are rare but lead solder was used with copper until banned in 1986. FL water utilities are required to test for lead. If your FL home was built before 1986, request a lead test from your utility. Identified by: dull gray, very soft pipe (scratches with a key). Lead test kits available at hardware stores.

CPVC

CPVC in Chloramine Areas (2000–2015 homes) — Inspect and plan replacement. CPVC installed in Miami-Dade, Broward, Tampa, and Palm Beach County homes during the 2000s is at risk of chloramine-induced brittle cracking. Hairline cracks first appear at joints and fittings. Identified by: cream/off-white or light gray plastic pipe. Stamped "CPVC" or "FlowGuard Gold." More rigid than PEX.

CAST

Cast Iron Drain Lines (50+ year old homes) — Plan for drain repipe too. Many FL homes that need supply repiping also have deteriorating cast iron drain lines. See our drain cleaning tool for cast iron timeline. Repipe supply and drain lines at the same time to minimize drywall opening costs. Identified by: heavy, dark gray/black pipe in floor or walls. Typically 2"–4" diameter. Makes hollow sound when tapped.

🏠 FL Slab Repiping: The Big Cost Factor

Why FL slabs cost more: Over 70% of Florida homes are built on concrete slab foundations — the opposite of northern states where crawl spaces are standard. Any pipe embedded in the slab requires jackhammering concrete, which dramatically increases repiping costs and creates restoration work (concrete patching, flooring repair).

Slab repipe strategies:

• Reroute overhead (preferred for PEX): Run new PEX through walls, attic, or ceiling rather than digging up the slab. Eliminates jackhammering. Most cost-effective in FL. Works well with PEX's flexibility.

• Tunnel under slab: Dig under the slab perimeter to access pipes without breaking the floor. Preserves tile but adds $500–$1,500 per section. Used when in-slab routing is unavoidable.

• Open slab (traditional): Jackhammer through concrete, replace pipes, patch concrete, restore flooring. The most complete solution but most expensive. Required for cast iron drains embedded in slab.

Post-tension slabs: Some FL homes (especially 1980s–1990s) have post-tension concrete slabs with embedded steel cables under pressure. Cutting a post-tension slab is extremely dangerous and can structurally compromise the home. Always verify slab type before any jackhammering — we check every job.
