Basement Finishing & Waterproofing in Manhasset, NY
Manhasset is one of Nassau County's most prestigious communities, and the basement finishing projects we complete here reflect that. Manhasset homeowners typically seek high-end finishes: home theater rooms with acoustic panels, wet bars with custom millwork and quartz countertops, wine cellars, home gyms with rubber flooring and mirrors, and guest suites with full bathrooms featuring subway tile and custom fixtures.
Manhasset's housing stock includes significant colonial, Tudor, and custom homes — many with full-height basements of 1,000 sq ft or more. These larger footprints give us the canvas for truly impressive finished spaces.
Groundwater in Manhasset is generally manageable given the community's higher elevation relative to some other Nassau County communities, but we always assess and address any moisture issues before finishing begins.
Permits for Manhasset go through the North Hempstead building department, which we work with regularly. We handle the full permit process including architectural drawings when required for complex projects.
