What gets checked before board goes up?
Framing plane, verified with a straightedge rather than by eye. Crowned or bowed studs get corrected, because a stud out by an eighth of an inch produces a bulge across three feet of finished wall that no amount of compound will hide.
Blocking gets confirmed for every known and likely future mount. Adding it after the wall is closed means opening it again.
What gets checked during installation?
Small details, checked as we go rather than discovered at the end.
- Fastener depth: dimpled just below the surface without breaking the paper face
- Fastener spacing per the assembly requirement
- Sheet layout planned to minimise butt joints
- Joints landed on framing where possible
- Board type correct for the location, particularly ceilings and wet areas
- On rated assemblies, layering and staggering per the listing
What gets checked during finishing?
That each coat is fully dry before the next goes on. This is the check most often skipped under schedule pressure and it is the one that causes the most callbacks.
That tape is properly bedded with excess worked out from underneath, so it bonds across its full width rather than blistering later.
That each coat is feathered wider than the last, so there is no ridge at the edge of the compound.
How do we verify the finished surface?
With a raking light. A bright light held almost flat against the surface and swept along it reveals ridges, dips, and texture variation that normal room lighting completely hides.
We do this from the direction of every window in the room, because a ceiling or wall that reads clean from one angle can show clearly from another. Anything the light finds gets corrected before handoff.
How can you check the work yourself?
Turn the room lights off, hold a bright flashlight almost flat against the wall, and sweep it across the surface. It takes two minutes and it is the same test we use.
- Ridges at joints or bead lines should not appear
- Dips or depressions along seams should not appear
- Fuzzy patches indicate the paper face was sanded through
- On a Level 5 wall, the plane should read uniformly with no visible joint bands
- Run a hand across the surface: you should not feel a transition at any joint
- Check for dust on ledges and sills, because primer over dust will fail
