Should You Supply Your Own Materials?

Contractors typically mark up materials 15–25% above their cost (which is already 10–20% below retail through trade accounts). For most homeowners, letting the contractor supply materials is simpler and the markup is modest. However, if you're doing a large project, buying materials yourself can save $300–$1,000+.

Buy Materials Yourself When:

  • Large project (100+ sheets)
  • You have reliable material delivery
  • You want to control specific board type/brand
  • DIY project — no contractor involved
  • You can get bulk lumberyard pricing

Let Contractor Supply When:

  • Small project (under 50 sheets)
  • No vehicle for hauling full sheets
  • Contractor's warranty covers materials too
  • Complex spec (multiple board types required)
  • You don't want to manage delivery logistics

Frequently Asked Questions

How much does drywall cost per sheet?

Standard 1/2-inch 4×8 drywall sheets cost $12–$15 at Home Depot or Lowe's in 2026. Fire-rated 5/8-inch Type X sheets cost $18–$24. Moisture-resistant (green board) costs $16–$22. Soundproof drywall runs $25–$40 per sheet. Buying 50+ sheets at a local lumberyard typically gets you 10–15% below retail pricing.

How many sheets of drywall do I need for a 12×12 room?

A 12×12 room with 8-ft ceilings needs approximately 18 sheets. Calculation: walls (2×(12+12)×8 = 384 sqft) + ceiling (12×12 = 144 sqft) = 528 sqft total. Divide by 32 (sqft per sheet) = 16.5, × 1.10 waste = 18.1 sheets. Always round up to 18 sheets minimum, and buy 2 extra for mistakes.

What is the difference between green board and purple board?

Green board is traditional moisture-resistant drywall with a treated paper facing. Purple board (QuietRock or National Gypsum's Hi-Strength) adds mold resistance to the core in addition to the face treatment. Purple board is preferred in very humid climates or areas with known moisture issues. Both cost $16–$22/sheet versus $12–$15 for standard.
