Sheetrock Your Walls,
Fewer Seams, Less Mud.
Free drywall calculators: sheet counts by wall size with waste factor, joint compound and tape estimates, screw counts, and material cost totals. No sign-up.
4x8 vs 4x12 Sheet Layout
Using 12-ft sheets reduces butt joints by 25%, drastically cutting taping time and sanding mess.
Joint Compound Pails
Accurate pail counts for taping coat, bedding coat, and finish skim coat across all drywall seams.
Fastener & Screw Densities
Field and edge screw spacing (12" oc field, 8" oc edge) ensures zero sagging on ceilings.

Building Code & Methodology
Ceilings First, Walls Second: The Hanging Order and Why It Exists
The drywall sequence is not tradition — ceilings rest on wall board edges, joints stagger, and the order prevents both sag and crack.
The Waste Factor, Honestly: Why 10% Is the Whole Answer
Sheet counts fail at the margins — cutouts, board breaks, and the sheet that "almost" fits. The real sources of waste, and when 15% is honest.
Drywall Finish Levels 1–5: What You Are Actually Buying
The six finish levels decide what paint hides and what it exposes. What each level includes, and which rooms need which.
