If you're facing a repipe on Marco Island, the material question usually comes down to two options: PEX or copper. Both are code-approved and widely used, but they hold up differently on a barrier island that sits inside Florida's most aggressive coastal-corrosivity band — and that local detail matters more here than it would twenty minutes inland.
PEX is typically 25–50% cheaper than copper, both in material cost and labor, since it's faster to run and needs fewer joints and fittings. For a whole-home repipe, that difference adds up quickly.
Nationally, copper often lasts 50–70 years under normal conditions, and PEX is typically rated for 40–50 years. But "normal conditions" is doing a lot of work in that copper number — on Marco Island's salt-air corrosion band, copper's real-world lifespan shrinks appreciably, particularly on outdoor-adjacent runs like hose bibs and fittings near the exterior. It's a meaningful part of why we typically lean toward PEX for homes here, especially anything close to open water.
PEX doesn't corrode the way copper can, and it resists the mineral scale that comes with Marco Island's reverse-osmosis-and-lime-softened city water better than copper does over time. Copper, on the other hand, is more vulnerable to pitting from both salt air and certain water chemistries.
Copper is UV-stable (PEX degrades in direct sunlight and needs to stay covered), rodent-resistant in a way PEX isn't, and it's the traditional, familiar material for homeowners who prefer it. It's also fully recyclable.
A few homeowners ask us whether PEX affects their insurance. It's worth confirming with your specific insurer and policy — some carriers have historically asked questions tied to early-generation PEX products from certain manufacturers, though PEX today is a mainstream, code-approved material used in new construction and repipes nationwide. We're not insurance advisors, so if this matters to your policy, it's worth a direct call to your carrier before you decide.
We inspect before we recommend anything, and the right material really does depend on your specific home — how close it sits to open salt water, what's already there, and what your budget allows. For most homes here, PEX's cost and corrosion resistance make it the more practical choice, but it's not a one-size-fits-all answer. See our repiping page for how we approach a full inspection and material recommendation.
