Marco Island’s Trusted Water Heaters Pros
Need water heater repair, replacement, or installation on Marco Island, FL? McGrath Plumbing, Drains & Water Heaters works across Marco every week — the high-rises along the beach, the waterfront homes of Old Marco and Tigertail, and the canal streets in between. Water heaters are literally in our name: tank and tankless, gas and electric, repair and full replacement.
Marco Island is a barrier island surrounded by salt water, and that makes it one of the harshest environments for a water heater in all of Southwest Florida. Salt air corrodes tank fittings, valves, and connections faster here than almost anywhere — a Marco water heater simply doesn’t get the lifespan it would inland. We install and protect them accordingly.
No hot water this morning? Rusty water, or a tank weeping in the garage or utility closet? Call (239) 376-3077 — our $68 service call brings a licensed plumber out, applied toward the repair if you move forward.
Water Heaters Services We Provide on Marco Island
Water Heater Repair
Failed elements, tripped high-limits, bad thermostats, leaking relief valves, gas pilot and igniter faults — most fixed same-day, with the parts that fail most in Marco’s salt environment on the truck.
Water Heater Replacement
When a tank corrodes through, we handle the whole swap: haul-away, code drain pan and expansion tank, corrosion-resistant fittings, permit and inspection — done right for the island.
Condo & High-Rise Units
Marco’s beachfront towers and condos need water heater work done to association standards — COIs, service windows, and clean logistics in shared buildings. We do it routinely.
Tankless & Salt Protection
Tankless suits Marco’s seasonal condos and tight utility spaces, and every install — tank or tankless — gets corrosion-resistant fittings and closer anode attention because of the salt.
Why Marco Island Water Heaters Fail Early
Salt air is relentless on a barrier island. Marco Island is ringed by the Gulf and its bays, so salt-laden air reaches every home — and it attacks the exposed metal on a water heater constantly: connections, valves, the tank jacket, and especially the anode. We see Marco heaters fail years earlier than identical units just a few miles inland. Every install we do here gets corrosion-resistant fittings and more frequent anode checks as standard practice.
Condo and high-rise realities. A huge share of Marco lives in beachfront towers and condos, where a failed water heater isn’t just your problem — a leak can reach the units below. Associations increasingly require aging heaters be replaced proactively, and the work has to meet building rules: insurance certificates, scheduled service windows, and tidy logistics in the towers. We handle all of it.
Seasonal homes, stagnant tanks. Marco has a heavy seasonal and snowbird population, and homes closed up May through November come back to sulfur odor, accelerated internal corrosion, and sometimes a leak that developed unseen. We do pre-departure shutdowns and welcome-back startups so the first shower of the season is a hot one.
Ian and the recovery. Hurricane Ian hit Marco hard, and storm-damaged and hastily-replaced water heaters are still shaking out across the island. If your heater was affected by flooding or replaced in a rush, it’s worth a professional look — salt-water intrusion does long-term damage that shows up later.
How Much Does Water Heater Replacement Cost on Marco Island?
Straight answer: a standard 40–50 gallon tank replacement, installed and permitted, typically lands in the low-to-mid four figures; tankless conversions run higher; straight repairs — elements, thermostats, valves — are often a few hundred dollars or less. Condo and high-rise installs may carry building-logistics considerations, which we’ll spell out upfront.
Every job starts with the $68 service call, applied toward the work, and you get a firm quote before we touch anything — no surprise line items, no upsells invented in your kitchen.

Marco Island Water Heaters FAQs
Why do water heaters fail so fast on Marco Island?
Salt air. Marco is a barrier island surrounded by salt water, and that constant salt exposure corrodes tank fittings, valves, and anode rods far faster than inland. We install corrosion-resistant fittings and check anodes more often to fight it.
How fast can you get to my Marco Island home for a water heater emergency?
Usually same-day. A leaking tank can’t wait — and in a condo, it can reach your neighbors. We answer 24/7 at (239) 376-3077.
Can you replace a water heater in my Marco condo or high-rise?
Yes — we do condo and tower work routinely, with the insurance certificates, scheduled service windows, and clean logistics associations require. Send us your building’s requirements and we’ll handle it.
My water heater was affected by Hurricane Ian. Should I worry?
Possibly — salt-water intrusion from storm flooding does long-term corrosion damage that can show up months later. If your heater was flooded or replaced in a rush after Ian, it’s worth a professional inspection.
How long do water heaters last on Marco Island?
Often less than the 8–12 year inland average, because of the salt. Corrosion-resistant fittings, regular anode checks, and yearly flushes all help extend the life of a Marco heater.
Is tankless a good option for my Marco condo?
Often yes — no tank corroding in a salt environment while you’re away seasonally, and it frees up tight utility space. We install and service tankless units and will size one to your household.
Do I need a permit to replace a water heater on Marco Island?
Yes — replacements require a permit, and condos often require association approval too. We pull the permit, handle the inspection, and coordinate with your building as needed.
What payment methods do you accept?
Cash, check, and all major credit cards — plus financing for larger jobs like full replacements and tankless conversions. Just ask when you call.
