For construction professionals working on homes built between the late-1970s and mid-1990s in Central or South Florida, polybutylene (PB) pipes present a significant challenge. These pipes, initially a cost-effective alternative to copper, deteriorate over time due to chlorine in municipal water, leading to leaks and potential water damage. With insurers often refusing coverage for PB failures, many homeowners are opting for repiping. The critical question is, what are the costs involved?
The cost to replace polybutylene in a 2-bath, single-story, 1,800 sq ft house typically ranges from $6,500 – $12,000. Here are some specific estimates:
These figures include materials, labor, wall opening, patching, permit fees, and post-repiping inspection. Our estimates reflect current market prices for copper or PEX.
Several factors influence the cost of repiping:
In Florida, PEX is often preferred due to its flexibility and resistance to leaks, while copper is valued for its durability in UV-exposed areas. Here are the costs:
Labor costs vary, with PEX generally requiring fewer fittings.
The 8th Edition of the Florida Building Code has introduced new requirements that affect repiping costs, such as fire-blocking and strap requirements for combustible piping.
Many insurers raise premiums for homes with PB piping. A signed contract may qualify for interim coverage and discounts upon completion. Financing options are available through licensed lenders.
The Martinez family’s 2,400 sq ft home experienced multiple leaks. Choosing PEX saved them 31% over copper, with a total project cost of $9,850. Their insurer reduced the annual premium by $720 after completion.
