Marathon seawall repair in the Florida Keys typically costs $185–$580 per linear foot. An 80-foot residential bulkhead runs $12,000–$37,000 for repair — Keys regulatory requirements and logistics add to costs. Call 866-398-9323 for a free estimate.

Yes — Hurricane Irma's 2017 direct hit on the Middle Keys caused catastrophic seawall damage throughout Marathon. Properties that received only surface repairs after Irma often have significant underlying structural damage. Post-Irma subsurface assessment is strongly recommended for any Marathon property not recently professionally inspected.

Marathon's coral rock and marl substrate creates unique failure modes — rather than sand void formation, Florida Keys seawalls often fail via marl dissolution that creates undermining patterns different from what mainland Florida contractors typically encounter. Our team has Keys-specific experience.

Monroe County's Florida Keys environmental regulations are among the most stringent in Florida. Structural seawall repairs require Monroe County building permits, DEP coastal construction compliance, and Army Corps of Engineers coordination. We handle all agency permitting for Marathon projects.

Annual inspections are strongly recommended for all Marathon Florida Bay and Hawk Channel properties. Post-storm inspection is critical given the Keys' direct hurricane exposure. Call 866-398-9323 to schedule.
