Basement Finishing & Waterproofing in Hicksville, NY

Hicksville is one of LI Basement Pro's core communities and has been since we opened in 2013. We have worked the exact housing stock that defines the area β the postwar Levitt-influenced ranches and cape-style homes built from the late 1940s through the 1970s.
These homes typically feature 550β750 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 has the process dialed in and typically achieves approval in 3β6 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.
