We are a family-run company, and our crews respond 24/7 whenever water shows up. Each job begins with a free inspection so you understand the full scope, including any salt-water complications, before any work starts. When water intrudes into your Marathon home, call (866) 688-0301 and we will make the trip out to you.
Serving the Middle Keys takes a company willing to make the drive and prepared for the conditions, and that is us. We understand storm exposure, salt, and marine humidity, and we know how to help the many seasonal owners who cannot always be on site. We dry thoroughly and document clearly, so a Marathon problem gets resolved for good rather than lingering between visits.
Why Marathon homes and businesses face water & mold risk
Marathon's low island geography leaves it highly exposed to hurricane surge and flooding, as Irma demonstrated when storm water inundated homes across the Keys. Surge pushes saltwater into ground floors, garages, and dockside structures, and the corrosive salt requires thorough rinsing and neutralizing along with drying, since it soaks in and holds moisture long after the water is gone.
The relentless salt-laden humidity of the Middle Keys keeps buildings damp year-round, and with many homes used seasonally, a slow leak can run undetected for weeks before an owner returns. Those conditions give mold all the moisture and time it needs to establish out of sight, so island problems are frequently well advanced by the time they are discovered.
Marathon spreads across Vaca Key and neighboring islands in the 33050 ZIP at the foot of the Seven Mile Bridge, a low chain barely above sea level with Florida Bay on one side and the Atlantic on the other and Boot Key Harbor cut into its underside. Irma made landfall just west of here in 2017 and gutted a large share of the housing stock, so much of what stands today is newer, elevated, and flood-code construction, but the underlying surge and salt exposure has not changed. Boot Key Harbor and the canals cut into Vaca Key put water on nearly every side of a Marathon lot, so even homes set back from the open Atlantic sit close to a waterway that can rise and push in during a storm.
Water damage & mold restoration built for Marathon
We understand the Keys' storm history and the demands it places on Marathon homes. Our crews reach properties along the Overseas Highway, rinse and sanitize after saltwater intrusion, dry structures completely, and remediate any mold present. We document storm and water damage in the detailed, photo-backed way that insurers require after a major event, so your claim has the support it needs.
Marathon owners choose Ultra Mold because Middle Keys service takes commitment backed by credentials. Our technicians are IICRC-certified to the ANSI/IICRC S500 standard, we are a licensed Florida mold remediator carrying more than $1 million in liability coverage, and we are fully insured. We dispatch 24/7 from Plantation, and we are honest with Marathon owners about travel time rather than promising a response window we cannot keep from the mainland.
A 4.9-star rating across 32 Google reviews reflects reliable work in a place still rebuilding from Irma. Every free inspection is honest about what corrosive saltwater will let us salvage, and every job runs on documented drying, daily moisture logs within the EPA's 24-to-48-hour window and humidity held below 60 percent, the only real defense against mold in constant salt humidity. For seasonal owners, we document conditions clearly so you can decide from afar.

Marathon water damage FAQs
Yes. Even the newer flood-code homes on Vaca Key sit low over the water in the 33050 ZIP, so surge and salt exposure remain, and a plumbing or roof leak in constant marine humidity still breeds mold. We dry thoroughly and verify with meters. Call (866) 688-0301.
We dispatch from Plantation, so reaching the Middle Keys near the Seven Mile Bridge means real travel time down the Overseas Highway. We are straight about that rather than over-promising, and we stage and respond as fast as conditions allow, 24/7.
Surge saltwater is corrosive and soaks deep, so we rinse and neutralize rather than dry over it, and some materials can't be saved that a clean leak would spare. We document storm damage in the photo-backed way insurers require after a major event.
We are a licensed Florida mold remediator, fully insured with over $1 million in liability coverage, and our technicians are IICRC-certified to the ANSI/IICRC S500 standard.
