Jacksonville is Florida's most populous city, 900,000+ residents spread across nearly 1,000 square miles, bisected by the St. Johns River with over 1,000 miles of waterfront along its tributaries and tidal creeks. On September 11, 2017, Hurricane Irma brought the worst flooding in Jacksonville's 250-year history, the St. Johns River rose to a record 5.57 feet, more than two feet above the 1864 record, inundating Riverside, San Marco, and downtown. Black Creek hit a record 26.4-foot crest, six feet over flood stage. A 2013 county report found that a Category 3 hurricane could create a 20-foot storm surge on the St. Johns. New data shows Jacksonville ranks second in the nation for growing flood risk, behind only New Orleans. We are a Florida state-licensed mold remediation team.
Hurricane Irma's September 11, 2017 passage west of Jacksonville produced what officials called an incident of historic proportions, the worst flooding in the city's 250-year history. A nor'easter in the days before Irma had already pushed water into local inlets; Irma's winds and surge piled additional water onto that base, driving the St. Johns River to a record 5.57 feet, surpassing the previous record set in 1864 by more than two feet. The flooding hit Riverside and San Marco, two of Jacksonville's most historic and desirable urban neighborhoods, with particular severity. Memorial Park and the Cummer Gardens in Riverside were completely underwater. San Marco Square's businesses, including longtime establishments, were shuttered for months. A city council member representing San Marco said years later that some businesses never fully recovered.
San Marco, ZIP 32207, known for its Mediterranean Revival architecture and direct St. Johns River proximity, and Riverside, immediately across the river, represent Jacksonville's highest-profile flood-prone historic districts. Flood risk databases list San Marco as having extreme flood risk, directly tied to its riverfront proximity. Hurricane Ian's 2022 passage, even though it tracked well south of Jacksonville, still caused tidal flooding that closed roads in Riverside and San Marco, demonstrating that these neighborhoods don't need a direct hurricane hit to experience flooding.
Beyond the river-adjacent historic districts, Black Creek in southwest Duval County hit a record 26.4-foot crest during Irma, six feet over flood stage, devastating the Middleburg area. New flood-risk database analysis places Jacksonville second in the nation, behind only New Orleans, for the rate at which flood risk is increasing. With downtown ZIP codes 32202 and 32204, the University of North Florida area in 32224 near the Timucuan Preserve, and dozens of neighborhoods along the St. Johns and its tributaries, Jacksonville's geography creates one of Florida's most extensive and varied mold risk landscapes.

Most jobs range from $1,800 to $6,500. Historic Riverside, Avondale, and San Marco homes near the St. Johns River with flood history often fall in the $2,500–$6,000 range. Free on-site inspection and written estimate before any work begins.
Yes, San Marco is specifically listed by flood risk databases as having extreme flood risk due to its direct St. Johns River proximity, and this risk is independent of any single storm event. Hurricane Irma's 2017 record flooding was the most severe example, but Hurricane Ian in 2022, which tracked well south of Jacksonville, still caused tidal flooding that closed San Marco roads. The neighborhood's beautiful Mediterranean Revival homes, many dating to the 1920s, sit in a location that experiences flooding more frequently than most Jacksonville neighborhoods, which means cumulative moisture exposure over time even without a major hurricane.
New flood-risk database analysis places Jacksonville second nationally, behind only New Orleans, for the rate of increase in flood risk. Several factors contribute: Jacksonville has over 1,000 miles of waterfront along the St. Johns River and its tributaries, much of its development sits at low elevations near tidal water, and sea level rise compounds with the same rainfall intensity increases affecting all of Florida. For homeowners, this means properties that haven't flooded historically may face increasing risk going forward, making baseline mold inspection and moisture management more important even for homes without a flood history.
