Buying Power That Lowers Your Cost
We buy a lot of material. Renovating 1,500+ apartments means we purchase kitchens, slab countertops, appliances, tile, hardwood flooring, and fixtures in volume, and New York's top suppliers reward that with pricing a single-building owner can't get on their own.
We leverage those long-standing supplier relationships on every job, so your units get landlord-grade finishes at a lower cost, delivered on a fixed price with meticulous attention to detail.
