A Level 5 finish applies a thin skim coat of joint compound over the entire wall and ceiling surface — not just at joints and fasteners — creating a completely uniform canvas. It is the only drywall finish that reliably hides surface variation under flat paint, in rooms with strong sidelighting, or under low-sheen eggshell in open-plan spaces. In Utah’s luxury custom home market, Level 5 is increasingly the standard in main living areas, primary suites, and anywhere trim and millwork quality calls for an equally polished wall surface. The premium over Level 4 is typically 15–30% of the total drywall cost — and it shows.
