What's actually involved

The crew removes the old flooring, inspects the subfloor and crawlspace framing for moisture damage (common in historic Ardmore, Buena Vista, and other nearby areas), replaces damaged sections of plywood or OSB, and applies self-leveling compound where the surface is uneven. Only after the subfloor is flat and dry does the new material go down.

Winston-Salem, NC specifics worth flagging

Newer Clemmons, Lewisville, and other subdivisions are usually the cleanest, fastest scopes, plywood subfloors ready for new flooring with minimal prep. Historic Ardmore, Buena Vista, and other homes, plus older Mocksville, Lexington, Thomasville, King, and Walnut Cove stock, more often have older plank subfloors, uneven joists, and prior water damage worth scoping carefully.

  • Plank subfloors behind original flooring (affects demo time)
  • Subfloor moisture damage from crawlspace humidity and prior leaks
  • Squeak repair and subfloor fastening, common in older intown stock
  • Crawlspace vs. slab construction (most historic intown Winston-Salem is crawlspace; many newer subdivisions are slab)
  • Moisture testing before installing over concrete or in below-grade rooms
  • Underlayment choice based on the new flooring material
