Technician extracting water from a stilt home in Marathon after a leak

Marathon is strung along more than a dozen islands in the Middle Florida Keys, from Grassy Key in the east to Knight's Key at the foot of the Seven Mile Bridge in the west, with Vaca Key at its center. The city sits at sea level, with the Atlantic and Hawk Channel on one side and the Gulf-side bays on the other, so nearly every property is close to open water. It is a boating and fishing community roughly midway between Key Largo and Key West, with Boot Key Harbor, a large natural anchorage, lying entirely within the city limits. Water Damage Florida provides 24/7 water damage restoration in Marathon, including emergency water extraction, surge and tidal flood cleanup, structural drying, mold removal and repair.

About a third of the housing here is seasonal or vacant, and the stock ranges from waterfront single-family homes to older canal-front and mobile-home communities that were heavily damaged in Hurricane Irma. Each responds to water differently, and the salt air works on all of them. Call (888) 435-4769 when you find water and we will get a crew moving down the Keys.

Emergency Water Damage Response in Marathon

Urgent calls from the Middle Keys usually begin with salt in one form or another. A corroded supply fitting or water heater connection fails in a waterfront home and runs across the floor into the bedrooms. A rental on Grassy Key or Fat Deer Key is found wet between guests. Wind-driven rain gets past a door on the ocean side of Vaca Key during a summer squall. And during a storm or an unusually high tide, water rises through the ground-level enclosures and lowest rooms of homes near the canals and Hawk Channel.

We plan every trip down the Keys so that pumps, extractors, air movers and dehumidifiers arrive together and drying starts on the first visit. From the moment we walk in we record the source, the path of the water and moisture readings, which becomes the foundation of your insurance claim. Our emergency water damage page describes what the first response involves.

Restoring Keys Homes From Stilt Houses to Canal-Front Cottages

Elevated waterfront homes keep their living space above most tidal flooding, but their ground-level enclosures, stairs and utilities take the water, and salt air reaches everything. Older canal-front homes and mobile homes sit close to the ground and absorb water into floors, walls and cabinetry quickly. In all of them, the materials that suffer are drywall, baseboards, cabinet bases, subfloors, insulation and any laminate or engineered flooring.

After extraction we map the moisture with meters and thermal imaging, remove what cannot be dried, and set up closed-space drying with dehumidifiers matched to the volume, because the humid island air will not dry a house on its own. Readings are logged daily and repair begins only when each material reaches its dry standard. Our water damage restoration service page walks through the full scope.

Flood Cleanup After Surge and Tidal Flooding

Hurricane Irma made U.S. landfall in the lower Keys in 2017 and caused significant damage in Marathon, with the Middle Keys experiencing four to six feet of surge inundation and some of the storm's strongest wind gusts; oceanside homes in the city were among those destroyed by the surge. Hurricane Ian in 2022 produced one to three feet of inundation across the Keys. Beyond named storms, the Keys as a whole are seeing increasing nuisance tidal flooding and are considered highly vulnerable to sea-level rise, so low yards and ground-level rooms can take water without a hurricane at all.

Salt water is contaminated and corrosive, and flood cleanup treats it that way. We pump and extract, remove porous materials the water reached rather than drying them, clean and disinfect hard surfaces, inspect metal, appliances and electrical components the salt touched, and dry the structure under air filtration. Ground-level enclosures, canal-front cottages and the lowest rooms of oceanside homes need the earliest attention. Stay out of standing water until the power is confirmed off, and see our flood restoration page for the sequence that follows.

Repair Once the Moisture Readings Say Dry

Repair on Marathon's islands begins when the drying logs confirm the structure is dry. That often means new lower drywall and baseboards, replacement of swollen cabinet bases and vanities, new flooring where laminate or plank failed, subfloor repair in older cottages and mobile homes, ceiling repairs under roof leaks, and paint. Salt-damaged hardware and fixtures are typically replaced at the same time.

The scope we propose is built from the photos and readings gathered during mitigation, so your adjuster sees what the water affected and where. For seasonal owners and rental operators we schedule around travel and bookings where possible, send progress photos, and keep the property secured and climate-controlled between visits.

Mold Removal in Marathon

Warm, salt-laden air and a large share of homes that sit closed for months make mold a routine finding after water damage in the Middle Keys. We find it behind the drywall of rooms that took tide or surge water, under subfloors and laminate in canal-front cottages, inside walls around leaking showers, in the back of kitchen cabinets after a line failure, around air handlers, and throughout seasonal homes and rentals where a leak ran with the thermostat set high.

Our mold removal isolates the area with containment and negative air, removes and bags affected porous materials, HEPA-vacuums and cleans what remains, and dries the space completely before rebuilding, always after the moisture source is fixed. More on our approach is on the mold remediation page, and our article on hidden mold after water damage is worth reading before you repaint anything that was wet.

Common Causes of Water Damage in Marathon

A sea-level city of islands, with waterfront homes, older canal-front and mobile-home communities and constant salt exposure, sees water damage from these sources most often:

  • Storm surge from the Atlantic and Gulf sides entering ground-level enclosures and low rooms
  • Nuisance tidal flooding reaching yards, driveways and slab-level homes
  • Salt-air corrosion of supply fittings, valves and water heater connections
  • Wind-driven rain past doors and windows on the ocean side during squalls and storms
  • Leaks in seasonal homes and vacation rentals that go unnoticed between occupants
  • Roof and flashing leaks in older homes and mobile homes damaged by earlier storms
  • Air conditioning condensate overflows during the long cooling season
  • Washing machine, dishwasher and ice maker line failures

How We Handle a Water Damage Job in Marathon

Crew cleaning out a ground-level enclosure on a Marathon waterfront property after storm surge

Every job across the city's islands follows the same eight stages, each verified before the next, so that what we rebuild is standing on a dry structure.

  1. Inspection and moisture mappingWe find the source, judge whether the water is clean or salt-contaminated, and map moisture through floors, subfloors, walls and cabinetry with meters and thermal imaging.
  2. ExtractionPumps and extractors remove standing water from living areas, ground-level enclosures and garages, including sandy surge and tidal water.
  3. Removal of unsalvageable materialsSaturated drywall, insulation, subfloor sections, pad, flooring and swollen cabinetry are removed and bagged.
  4. Drying and dehumidificationAir movers and dehumidifiers run in the closed home, with readings logged daily until every material reaches its dry standard.
  5. Cleaning and disinfectionSurfaces exposed to salt water or long-standing moisture are cleaned and treated while HEPA air filtration runs.
  6. DocumentationThe photos, moisture logs and written scope are organized into a claim-ready record.
  7. RepairDrywall, subfloors, trim, cabinets, flooring, fixtures and paint are restored to match the home.
  8. Final verificationA closing moisture survey and walkthrough confirm the home is dry and finished.

Steps to Take While We Are on the Way

With the drive down the Keys, what you do first has a real effect on the outcome. Take only the steps that are safe and leave the rest to the crew.

  1. Shut off the waterTurn off the valve at the fixture or appliance, or the main supply at the house. For a roof or door leak, catch what you can and move furniture clear.
  2. Do not enter water near electrical equipmentStay out of a flooded enclosure, garage or room where outlets, pumps, appliances or the panel may be wet. Switch off breakers only when the panel is dry and you can reach it without wading.
  3. Treat tidal and surge water as contaminatedKeep everyone and every pet out of it and do not try to clean it up yourself.
  4. Move belongings up and outLift rugs, electronics, gear and light furniture off wet floors; put foil or blocks under heavy pieces.
  5. Document the damagePhotograph the source, the water line and every affected area, including ground-level enclosures, before anything is moved.
  6. Keep the home closed and coolIf power is safely on, run the air conditioning and keep doors and windows shut against the humid air.
  7. Call (888) 435-4769Tell us which key the property is on, the source of the water, how long it has been wet, and whether the home is elevated.

Marathon Water Damage FAQs

Only the ground-level enclosure under my stilt home got wet. Do I still need restoration?

Yes. Salt water in an enclosure soaks drywall, framing and stored belongings, corrodes utilities, and feeds mold that can spread upward. We extract, remove what the water reached, clean and disinfect, and dry the enclosure so it does not become a problem for the living space above.

Can an older canal-front cottage or mobile home be restored after flooding?

Often, but they absorb water quickly and low floors and subfloors are usually involved. We assess the extent with moisture meters, remove saturated materials, dry and verify, and repair subfloors and walls. We tell you plainly after the survey what is worth restoring.

Why do plumbing fittings fail so often in the Keys?

Salt air corrodes metal fittings, valves and water heater connections faster than inland conditions. Inspecting and replacing aging connections is the best prevention, and when one fails, fast extraction keeps the damage contained.

We run a vacation rental. How do you work around guests?

We coordinate with you or your manager on scheduling, work between bookings where possible, keep the property secured and climate-controlled, and document the loss for the owner's policy so the claim is straightforward.

How do you verify that a home is actually dry?

With moisture meters and thermal imaging, logged for each material every day until readings return to the dry standard. Repair starts only after that, so a finished wall or floor is not hiding moisture behind it.

Do you also cover Key Colony Beach, Duck Key and the rest of the Middle Keys?

Yes. Our crews serve Key Colony Beach, Duck Key, Conch Key, Layton, Islamorada, Big Pine Key and Key West, and the rest of Florida through our service areas.
