Walls and Ceilings Smooth Enough for Any Paint Sheen
Level 4 is the finish most walls get and it hides fine under flat paint, but semi-gloss, dark colors, or a big window throwing raking light demand a Level 5 skim coat over the entire surface. Campbells Carpentry LLC hangs and finishes both. Our drywall installation and repair work covers new board for additions, basements, and garages, texture matching, hole and crack patches, nail pops, and water-damage replacement in Warrenton, MO, Wright City, and Foristell.
Most of our drywall goes up inside projects we are already framing, so the same hands that set the studs check that every joint lands on solid backing. As an owner-operated shop, we give straight answers about whether a wall needs a patch or a full sheet, quote free estimates, and keep the conversation one-on-one from first call to final sanding, as we have for 5+ years. Request an estimate through our contact page whenever you are ready.
Drywall Installation and Repairs We Handle
New Drywall Installation
Additions, basements, and garages get 1/2-inch board on walls and ceilings, with 5/8-inch Type X on garage ceilings under living space. Screws go 12 inches apart on ceilings, 16 on walls, sheets run horizontal to shorten joints, and every edge lands on framing.
Drywall Finishing and Texture
Taping decides the wall. We embed paper tape in setting compound, float two more coats of all-purpose mud with a wider knife each pass, and sand under a low-angle light. Orange peel, knockdown, and skip trowel are matched to a sample first.
Hole and Crack Repair
Doorknob dents and anchor holes under 4 inches take mesh and spackle; holes up to 6 inches get a California patch, which uses the paper face as its own tape. Bigger openings need backer strips, and recurring cracks get fresh tape, not filler.
Water-Damaged Drywall Replacement
Stained, sagging, or crumbly board never dries back to strength, so we cut it out to the nearest studs, dry the cavity, and check the insulation behind it before hanging replacement sheets. Fixing the leak comes first, or the patch is pointless.
Garage and Basement Drywall
Insulating and boarding a garage follows one sequence: batts in the bays, board hung tight to the top plate, and every joint taped and mudded so the fire separation is continuous. Basements begin with a moisture check along the foundation walls.
Ceiling Drywall and Repair
Overhead work punishes shortcuts, so ceiling board goes up on a lift, gets screwed off before the lift comes down, and has its joints staggered. We fix sagging panels, popcorn texture damage, and the seam cracks that open when roof trusses move seasonally.
Why Choose Us for Drywall Installation & Repair
Framing Checked Before Hanging
Because we frame as well as finish, a bowed stud or a missing nailer gets fixed before board covers it, not shimmed after the mud is on. You get true walls because the skeleton underneath was straight, and compound cannot fake that.
Repairs That Disappear Under Paint
A patch you can find with a flashlight is a patch done halfway. We feather compound well past the repair, prime the bare mud so it takes paint like the old wall, and match the texture before any roller arrives.
Texture Matched, Not Approximated
Orange peel from 1998 does not look like orange peel from a rental sprayer today, so we test the pattern on scrap, adjust air pressure and mud thickness, and only then hit the wall. Knockdown gets the same attention, trowel timed to match.
Fire Separation by the Book
The wall between your garage and your kitchen is a fire barrier first and a wall second. We hang the thickness the code calls for on each surface, fill every seam, and seal penetrations so the rating holds at inspection.
Dust Kept to the Room
Sanding is the part everyone dreads, so we hang plastic at the doorways, run a vacuum-attached sander on the big flats, and wipe the walls down before primer. Your furnace filter and kitchen counters stay clean, and the mess leaves when we do.
Level 5 When It Matters
Flat paint forgives a Level 4 finish; a dark accent wall with afternoon sun across it does not. We tell you which rooms need the full skim coat, so you pay for the extra step only where the light would expose the joints.

Smooth Walls Start With the Board Behind the Paint
Paint gets the credit, but the board and the mud underneath decide whether a wall looks right at 4 p.m. when the sun comes across it. Campbells Carpentry LLC hangs, tapes, textures, and repairs drywall with the care we put into the framing behind it, and we say so up front when a room needs a Level 5 finish and when a Level 4 will do. Homeowners in Warrenton, MO, Truesdale, MO, and across the Greater St. Louis area call us for one patch or a whole basement, and neither one gets rushed. When the timing suits you, reach us through the contact page and we will set up a free estimate.
Frequently Asked Questions
How big of a hole can you patch in drywall?
Roughly 6 inches across is the limit for a patch; past that, the surrounding board loses too much support and a cut-in piece screwed to fresh backing is the better repair. Under 4 inches, mesh and a few coats of compound will do.
Should drywall be hung vertically or horizontally?
Horizontally on most residential walls. Running sheets sideways puts the tapered joint at a comfortable finishing height, shortens the total run of seams, and bridges more studs for a stiffer wall. Vertical hanging makes sense on walls taller than a sheet is long.
How many coats of mud does drywall need?
Three is the standard: a tape coat, a fill coat, and a finish coat, each feathered wider than the last and left to dry overnight. A Level 5 finish adds a fourth, wall-wide skim for gloss or deep colors.
Why do nails pop out of drywall?
Lumber shrinkage, mostly. Studs framed wet shrink through the first heating seasons and push the fastener head through the paint. Campbells Carpentry LLC fixes pops around Warrenton, MO, as we have for 5+ years: a new screw 1 1/2 inches from the old one.
How do I know if my drywall needs repair or replacement?
Press on it. Board that flexes, crumbles, or feels soft has been wet and needs replacing back to the studs. Surface damage on firm board, meaning dents, holes, cracks, and popped fasteners, is repairable, as are most stains once the leak is fixed.
Will the repaired area match the rest of the wall?
Yes, if the texture is matched and the whole wall is repainted. A patch feathered wide, primed, and textured to the original pattern disappears, but paint on only the patched spot shows a sheen difference, so plan on rolling corner to corner.
How long does drywall repair take?
Small patches take 2 to 3 visits over as many days, because each coat of compound needs about 24 hours to dry before the next. Setting-type compound cures in 20 to 90 minutes and lets us finish a same-day repair when needed.
What causes drywall cracks?
Movement. Hairline cracks above doors come from shrinking framing or settling, and long ceiling-seam cracks often mean truss uplift in winter. Campbells Carpentry LLC sees both across Warrenton, MO, where expansive clay keeps houses moving, and we retape every crack rather than fill it.
