Precision Waterproofing & Renovation
Our basement renovations cover waterproofing, framing, electrical, flooring, lighting, and egress windows where required. We handle moisture control first, so the finished space stays dry long after the project ends.
NYC Focus: Built for Older Stock
New York's older housing stock and clay-heavy soil make basements prone to seepage, especially in Queens and Westchester County. We assess drainage and foundation conditions during the site visit and build the waterproofing plan around your specific property, not a generic checklist.
Code Compliant
Full permitting and code compliance handled in-house for structural and egress requirements.
Factors Affecting Your Basement Renovation Cost
Waterproofing Needs
Assessing existing seepage or historical moisture issues.
Egress Requirements
Window installation and structural modification if required by code.
Framing Complexity
Navigating around existing utilities, HVAC, and support columns.
Finish Level
Material selection for flooring, drywall finish, and custom fixtures.
The transformation of a basement depends mainly on the waterproofing needs, the incorporation of regulatory emergency exits and the quality of the finishes selected to optimize the space.
