Drywall Installation and Finishing

Hanging and Finishing Board So It Disappears

Most of what we do is ordinary drywall work, and the standard we hold on it comes from the sound side of the business. A wall that is hung tight, screwed to pattern and sealed at the plates is quieter than one that is not, before anybody adds a single extra layer. Good installation is the cheapest acoustic improvement available and it is free with the job.

New Walls and Ceilings

Board goes up with joints staggered so no seam runs through the full thickness of an assembly, screws set to the depth the manufacturer specifies, and sheets butted tight rather than left with a gap for the tape to bridge. A gap gets filled and it will crack later.

Ceilings get five eighths board on framing at twenty four inches, because half inch sags between joists in a room that reaches the temperature a Riverside attic reaches in August. That is not a preference, it is what the board is rated for.

Level Four and Level Five

Finish levels are a real standard and worth understanding, because the difference is money.

Level four is three coats over the tape at flat joints, three over the corner bead, and screw heads coated. It is the normal residential finish and it is correct under a flat or matte paint and under any texture.

Level five adds a thin skim over the entire surface, so the paper facing and the joint compound absorb paint identically. You want it where a wall takes direct light across it at a low angle. In Riverside that means the west facing walls of a room with an afternoon window, where the sun rakes across a flat sheen and every joint and screw line reads as a shadow. Specifying level four there and then buying a semi gloss paint is how people end up unhappy with work that was technically to spec.

We will tell you which one a room needs. We will also tell you when a room does not need level five, because it is a real cost and most walls do not.

Texture Matching

Riverside interiors run heavily to orange peel and knockdown. Both are sprayed and both vary by the hand that sprayed them, so matching an existing room is a test board exercise, not a product selection. We shoot samples at the nozzle setting and the mud thinning we think are right, hold them against the wall, and adjust before anything goes on the actual repair.

The other half of a good match is the feather. A patch finished tight to its edges reads as a rectangle the moment a lamp is switched on beside it. Feathering wide takes longer and it is the difference between a repair you cannot find and one you notice for years.

Repairs and Nail Pops

Slab on grade housing moves. A slab that takes up a little water in a wet winter and dries out through an inland summer will settle and shift, and the framing on top of it moves with it. Fasteners work loose and push a small dome of paint off the wall.

A pop is not fixed by filling it. The old fastener gets removed or driven properly, new screws go in a couple of inches either side to pull the board back tight against the stud, and then the area is coated. Skimming over a loose fastener buys a season.

We also cut out and replace water damaged board rather than drying and painting it, cut in patches with a backing strip so the piece cannot rock, and rebuild corners that have been knocked through rather than filling the bead.

Garage Conversions and Type X

Garage conversions are a large share of our work along the 91 corridor, and they are where we find the most missing fire rated board. The wall between a garage and the house, and the ceiling under habitable space above a garage, are rated assemblies. They take Type X board, at the thickness the assembly calls for, taped and finished, with penetrations firestopped.

Somebody framing a room in a garage over a weekend will very often board it in half inch because that is what was on the shelf. It is out of sight, it looks finished, and it is wrong. We replace it. This is not an upsell, it is the part of the job an inspector looks at and the part that matters if there is ever a fire.

Working in Dry Inland Air

Mud dries faster here than the bucket suggests, particularly on a Santa Ana day when the humidity drops into the teens. That is mostly good news for the schedule. It becomes a problem on a wide feather, where the leading edge of a coat can go off before you have pulled it out, and on hot mud where a ninety minute product behaves like a forty five minute one. We mix smaller batches, work shorter runs, and keep the sanding for the following morning. A rushed feather in dry air is the most common reason a patch shows.
