Our Process

From Raw Land to Finished Home

Here's how White Mountain General Contractor manages a project start to finish, using our current Connally build as the example.

1

Permitting & Site Design

We start with raw land — bringing in the septic designer and working the project through town permitting before anything breaks ground.

2

Clearing & Site Work

A logger clears the land, followed by our site work contractor to prep the building pad and access.

3

Foundation & Subfloor

Our concrete contractor pours the foundation; WMGC builds the subfloor in-house.

4

Framing — 99 Construction Inc.

Our framing partner erects the frame and sheaths it to a weather-tight condition, ready for the next trades.

5

Trades to Finish

WMGC brings in and manages every remaining sub — mechanicals, insulation, finishes — through to a finished home and keys in the client's hand.
