Flooring

What this trade is

Flooring covers subfloor prep, underlayment, and finished floor install across hardwood (site-finished or prefinished), engineered, LVP/LVT, and specialty (cork, bamboo, polished concrete). Subfloor flatness and moisture management are the real skill set.

Why a GC needs a verified flooring sub

Flooring subs who have worked the same GC's projects over time know that GC's preferred transitions, expansion-gap conventions, and threshold details. Flooring is also where moisture issues surface — a flooring sub with a relationship will pause and flag slab moisture instead of installing over it.

Regulatory landscape

License structure varies by jurisdiction. AskBaily verifies against the licensing authority that applies to the project location — not the GC's headquarters. A few representative jurisdictions:

• California — CSLB
  C-15 (Flooring and Floor Covering)

  Separate C-15 classification. Hardwood-finishing sub-specialty commonly overlaps.

Quality signals AskBaily tracks

Each declared sub accumulates these signals across projects. They appear on the sub's digital twin and on the GC's public sub-trade view.

• Slab-moisture testing

  Whether the sub tests slab RH before install rather than relying on visual inspection.

• Transition detailing

  Consistency of thresholds between tile, wood, and carpeted rooms — a signature of a disciplined installer.

Cross-trades

Flooringsits at the edge of several other trades. Coordinated scheduling between these is the GC's core responsibility; the sub-trade graph makes the coordination visible across projects.
