Industry-standard finish levels
We finish to the GA-214 / AWCI Levels of Finish standard - Level 4 for typical wall paint, Level 5 skim coat where glossier paint or raking light demands it.

The stage that decides whether walls look flat under real light or reveal every seam. We take it seriously.

We finish to the GA-214 / AWCI Levels of Finish standard - Level 4 for typical wall paint, Level 5 skim coat where glossier paint or raking light demands it.
Each coat wider than the last (8", 12", 16"+) so transitions are gradual, not visible lumps.
Metal, vinyl, or paper-faced bead selected for the location - set true and mudded tight so corners look crisp for the life of the wall.
Whether spray orange peel, knockdown, or smooth, texture applied consistently across the whole surface - not blotchy in one corner.
We wait between coats. Rushing dry time is the #1 cause of cracked seams six months later.
Vacuum-attached sanders and containment where needed. Your finished-drywall dust doesn't have to end up on every horizontal surface in the house.
The gypsum industry defines six levels of drywall finish (Level 0 through Level 5). Level 4 is the standard for most residential walls that will receive flat or eggshell paint - two coats of compound over tape, one coat over screws, sanded smooth. Level 5 adds a full skim coat of thinned joint compound across the entire wall surface, then sanded. Level 5 is worth the upgrade under glossy paint, in rooms with strong side-lighting (walls facing large windows), and for anywhere the eye will look critically across a large surface.
Bad finishing shows worst under three conditions: raking light (natural or artificial light hitting a wall at a low angle), glossy paint sheens (satin, semi-gloss, high-gloss), and open expansive walls with no trim or furniture to break up the eye's sweep. A rec room with matte paint and lots of stuff on the walls is forgiving. A great room with 12' walls, tall windows on the west side, and semi-gloss paint reveals every imperfection. We recommend Level 5 whenever any of those conditions apply.
First coat: bed paper tape into a thin layer of compound on every seam, coat corner bead, and cover every screw. Second coat: 8-10" wide over seams and screws, sanded lightly when dry. Third coat: 12-14" wide, feathered smooth, sanded finely. Level 5 adds a fourth pass - a skim coat rolled or sprayed across the entire wall and knocked down smooth. Between every coat, proper dry time (usually overnight for premixed compounds, less for setting-type). No shortcuts.
Smooth (no texture) is the current preference in high-end residential and modern commercial - and it demands Level 5 finish underneath to look right. Orange peel and knockdown are sprayed on and hide minor imperfections, which is why they're common on production homes. We apply all three, and we match existing textures on repairs. For remodels tying into existing textured walls, we sample and match before touching your walls.
Finished walls should be dust-wiped, primed if you want us to prime, and the site should be clean. We coordinate directly with your painter about primer selection (some finish coats need different primers) and hand off walls they can spray without spending a day on prep. Painters who've worked with us before know what to expect.
We walk the space, review your paint plan and lighting, and recommend Level 4 or Level 5 per room.
Paper tape bedded, corner bead installed, screws covered. Full dry time before sanding.
Each coat wider and feathered smoother. Light sanding between.
For Level 5: full-surface skim, sanded fine. Then texture if specified, primer, ready for paint.

Level 4 is standard finish - three coats over tape and two over screws, sanded smooth, appropriate for flat and eggshell paint in normal light. Level 5 adds a full skim coat of thinned compound across the entire wall, sanded smooth. Level 5 is the right choice under glossy paint, in rooms with strong side-light, and on large uninterrupted wall surfaces.
Finishing only (hang done separately) typically runs $1.25-$2.25 per sq ft for Level 4 and $2.00-$3.25 per sq ft for Level 5, depending on scope, ceiling height, and access. Hang-and-finish combined runs $2.25-$4.50 per sq ft. We give firm written quotes after a site visit.
A single room typically finishes in 4-6 working days including compound dry time between coats. Whole-house finishing runs 1-3 weeks depending on square footage. Rushing dry time causes cracked seams later - we don't do that.
Rarely. Level 5 is worth the upgrade in rooms with glossy paint, strong side-light from windows or sconces, or large open walls (great rooms, dining rooms, entryways). Bedrooms and utility spaces with flat paint are almost always fine with Level 4.
Almost always one of: mesh tape used with premixed compound on butt joints (mesh flexes, cracks appear), coats rushed without full dry time between them, or framing movement behind the seam. We use paper tape on flat seams, allow full dry time, and use setting-type compound where movement is a concern.
Yes - we take over finishing on plenty of projects where the hang was done by others. We'll walk the hang first and flag anything (bad screws, unbacked seams, bowed panels) that will affect the finish. Sometimes rework is needed; we'll be honest about it.
Yes. For repairs and remodels tying into existing textured walls, we sample the existing texture, mock up on scrap, and match before applying to your walls. See our texture matching service page for details.
Sanding produces the most dust in the whole drywall process. We use vacuum-attached sanders (which capture the majority of dust at the tool), plastic containment on occupied remodels, and clean up daily. It's still a dusty phase - we're honest about that - but nothing like the reputation.
Yes. Lake-effect humidity swings, freeze/thaw cycles, and dry winter forced-air heat all move drywall subtly. We plan panel acclimation, use appropriate joint compounds for the season, and time coats so seams don't crack when your house cycles from 65% summer humidity to 20% winter humidity.
Yes, regularly. We coordinate handoff timing and primer selection with your painter (or a painter we partner with) so there's no gap between finished drywall and paint start. This is a big deal on remodels with tight schedules.
