Buffalo Custom Basement Finishing provides full basement finishing, remodeling, waterproofing, and egress window installation for homeowners throughout Buffalo, NY and the rest of Western New York — licensed, insured, and locally owned. We handle framing, drywall, flooring, electrical rough-in, French drain systems, sump pump installation with battery backup, and egress window cutting, coordinating every trade under one contractor from raw concrete to finished living space.

Western New York’s freeze-thaw cycles, hydrostatic pressure, and aging block and poured concrete foundations create waterproofing challenges that require site-specific drainage solutions before any finishing work begins. We pull permits, manage inspections, and meet all New York State and Erie County building codes — so you can transform your unfinished basement into a dry, comfortable extension of your home, whether that's a guest suite, home office, gym, or family room.
