Polybutylene Pipe Replacement Florida Cost Calculator

$4,500 to $12,000 for a typical 1,500 to 2,500 sq ft. Florida home. Or $2.00 to $5.00 per linear ft for the repipe plus $1,200 to $4,000 in drywall patch and texture. A Florida slab home forces an overhead PEX re-route adding 30 to 50 feet of pipe versus a straight swap, which drives the upper range. Plumber labor runs $55 to $130 per hour (BLS OEWS 47-2152). A 100-linear-foot job at the $3.50/ft mid-range plus drywall and permit lands near $7,500.

Florida municipal water carries 1 to 4 ppm chlorine and chloramine to control bacteria in warm distribution lines. Oxidants at that level attack the acetal resin fittings and the PB tube wall, causing micro-fractures. Well-water homes on the same pipe lasted longer because they received 0 ppm free chlorine — eliminating the oxidant load that triggers PB degradation. The Cox-Shell Oil class settlement (1995–2009) documented failure rates climbing sharply past 10 to 15 years of chlorinated exposure. With acetal fitting crack rates reported at 2x to 3x higher than in low-chlorine markets. Exactly the Florida municipal profile.

PEX is the correct choice in nearly every Florida poly-B case, winning on 3 of 4 cost and risk criteria. PEX-A or PEX-B resists the chlorine that destroyed the original poly-B, flexes through existing wall cavities without new access cuts. Costs $0.40 to $0.80 per linear ft versus copper at $2.00 to $5.00 per linear ft (BLS PPI PCU331420331420). Copper sweat joints demand torch work in a Florida attic — a fire risk in a closed soffit where heat routinely reaches 130°F to 150°F. And copper wins only where local code or an HOA architectural rule mandates it.

For a 50 linear ft pipe run, No. Insurance pays only for sudden water damage after a failure, not preventive replacement, leaving the full $4,000–$8,000 repipe cost to the homeowner. Citizens Property Insurance and several private carriers list active poly-B as a non-renewal or non-bind condition affecting roughly 30% of Florida policies written before 2010. So the repipe restores insurability rather than being funded by the policy. After the job, submit the permit close-out and a licensed plumber's certification letter ($150 to $400) to the underwriter, because the letter. Not the receipts — is what clears the flag.

1 to 2 working days for a licensed crew on a 1,500 to 2,500 sq ft. Florida home. With water shut off for most of the active plumbing work. And paint add another 2 to 4 days on a separate schedule because the rough-in inspection under Florida Building Code must pass before closing walls. A missed inspection slot stalls the whole sequence by 24 to 48 hours. PEX support every 32 inches and copper flux-cleaned joints are critical for 50-year reliability. Florida attic heat reaching 150°F+ makes routing through conditioned space the only option that avoids early degradation.

Technically yes, but spot repairs are a false economy because the entire system shares the same chlorine-degraded material and acetal fittings. Florida homeowners commonly see a 2nd leak within months of a 1st patch. The $2.00 to $5.00 per linear ft whole-house rate exists precisely because partial repipes do not satisfy insurers or buyers. A home with documented poly-B still present fails resale inspection even if the visible leak was patched. And triggers non-renewal at renewal dates 30 to 90 days out.
