What's actually involved

The crew removes the old flooring, inspects the subfloor and crawlspace framing for moisture damage (common in older Inside-the-Beltline Raleigh, downtown Durham, and Chapel Hill stock after long humidity exposure), replaces damaged sections of plywood or OSB, and applies self-leveling compound where needed.

Triangle-area specifics worth flagging

Newer Cary, Apex, and other subdivisions are usually the cleanest, fastest scopes, with plywood subfloors ready for new flooring with minimal prep. Older Inside-the-Beltline Raleigh bungalows, downtown Durham four-squares, and historic Chapel Hill and Carrboro stock more often have crawlspace moisture damage worth scoping carefully.

  • Moisture testing before installing over crawlspace-adjacent subfloors
  • Squeak repair and subfloor fastening
  • Self-leveling compound for dips and high spots
  • Plywood or OSB replacement where rot or water damage is found
  • Underlayment choice based on the new flooring material
