Drainage Solutions for Longboat Key Builders & Property Owners
Lethermon Grade Excavations provides professional drainage work in Longboat Key, Sarasota & Manatee Counties. We install French drains, swales, catch basins, and regrading that move water away from structures and keep low-lying Florida lots from flooding.
Longboat Key is a 12-mile barrier-island town of high-end custom homes and estates, and the excavation work here is premium residential — building pads, pool excavation, driveway and lot grading, and teardown demolition, often on waterfront lots with tight access. We've completed several Longboat Key projects.
