Where the money actually goes
For an average 1,800 sq ft home in Hattiesburg at roughly $5,336, a typical bill splits like this:
| Line item | Share | Cost |
|---|---|---|
| Labor | 40% | $2,134 |
| Materials | 45% | $2,401 |
| Site prep & equipment | 9% | $480 |
| Overhead, disposal & finishing | 6% | $320 |
The labor share is why identical projects diverge so sharply between states. It is also why a bid that comes in far below these numbers usually means a thinner specification or a crew cutting preparation, not a genuine bargain.
