Basement Finishing & Waterproofing in Hicksville, NY

Basement finishing in Hicksville NY by LI Basement Pro

Hicksville is LI Basement Pro founder Dan Farrelly's home community. He grew up on Long Island's North Shore, started his finish carpentry career here, and built his business serving the exact type of housing that defines Hicksville β€” the postwar Levitt-influenced ranches and cape-style homes built from the late 1940s through the 1970s.

These homes typically feature 550–750 sq ft unfinished basements with cinderblock or poured concrete foundations. The Hicksville-area soil β€” clay-heavy till over sandy outwash deposits β€” creates significant hydrostatic pressure during wet seasons. We always assess for moisture before recommending a finishing timeline.

Hicksville homeowners commonly ask about bedroom conversions (requiring egress windows), home gym spaces, and home offices. Permit applications go through the Nassau County Building Department β€” our office manager Karen has the process dialed in and typically achieves approval in 3–6 weeks.

We've completed more than 50 basement projects in Hicksville alone, ranging from simple LVP flooring and drywall upgrades to full luxury finishes with wet bars and full bathrooms. Our Syosset office is just minutes away, making us highly responsive for Hicksville estimates and any on-site follow-up during your project.
