Basement Renovations
in Roslyn
Most Roslyn homeowners are sitting on 400–600 square feet of unfinished basement space that could be functioning as a family room, home office, gym, or income-generating rental unit.

Waterproofing First — Always
Basement finishing in Roslyn must begin with a moisture assessment. Nassau County's water table and clay soil can create basement moisture conditions that destroy finished work within a few seasons if not addressed first. TrueCraft evaluates drainage, sump pump capacity, foundation wall condition, and exterior grading before recommending any finishing work — and we address moisture issues as part of the renovation scope, not as an afterthought.
Egress Windows & Legal Bedrooms in Nassau County
Any basement bedroom in Nassau County requires a properly sized egress window — a minimum net clear opening that allows occupant escape and firefighter entry. Most original basement windows don't meet code. TrueCraft installs egress windows as part of our basement renovation scope: excavation, window well installation, window installation, and permit compliance through the Town of Hempstead or Town of Oyster Bay. A code-compliant egress bedroom dramatically increases a home's appraised value and the utility of the finished space.
