Flooring, Drywall & Interior Finishes in Altadena
What hollow plaster can hide, how it changes the plan, and how floors and walls are redone with a written scope in older Altadena houses.
Plaster that sounds hollow under a knuckle may be covering a cracked stud, an abandoned pipe run or a loose bundle of cloth-wrapped wire. In an older Altadena house, finding any of those turns a cosmetic patch into a repair with a sequence. Framing is corrected first, then wiring and plumbing are updated, then new drywall closes the wall and floors are finished last.
When the hollow spot is opened
A small cut at the hollow spot shows what the plaster is hiding. A stud with a long split gets a new one fastened alongside it. A pipe that no longer serves a fixture is cut out and capped where it leaves the live line. Old wire is followed to the panel, and anything cloth-wrapped is replaced before the wall closes. Each of those findings is written up as a separate scope item, so a surprise behind a wall is priced and explained before the next step begins and nothing waits for the final tally.
Closing it up and finishing
With the framing, wiring and pipes in good order, the opening is closed with drywall, shimmed out to the depth of the plaster so the face lands flush. Joints are taped, filled and feathered wide, and the surface is textured to echo the adjoining rooms. Floors come last. Boards worth keeping are refinished, and any new flooring is chosen to meet them at a level threshold, with a reducer strip only if a small step is left at the opening, and a final vacuum pass before anyone walks across it.

Flooring, Drywall & Interior Finishes in Altadena: common questions
Often, though past sandings can leave less wood than the surface suggests. At the walk-through we look at a board edge at a floor vent or threshold and test a small spot. Replacement boards can come from a closet or salvage, and the whole floor is refinished at once so old and new match in tone and sheen.
Hairline cracks in plaster that remains bonded can be patched and kept, along with the trim lines it carries. A wall that sags or crumbles has lost its grip on the lath. Drywall is the cleaner choice for any wall opened for framing repair, and a wide feathered seam hides the change.
Wait for a test result first. Older tile and mastic may contain asbestos, which is dangerous only when dust gets loose, so nothing is scraped or broken while a lab sample is pending. Clear results allow normal removal. A positive result brings handling rules that govern the method and the disposal.
