Asbestos sampling first
Any acoustic ceiling sprayed before the mid-1980s gets sampled and lab tested before a scraper touches it.
Glendale Quality Drywall handles popcorn ceiling removal in Glendale, CA — sampling, scraping, skim coating and retexturing acoustic ceilings in occupied homes, with containment that keeps the scrapings in the room they came from. Most of the housing stock here still has sprayed acoustic ceilings from the 1960s and 1970s, and taking one off well is far more about the two skim coats that follow the scrape than about the scraping itself.
Sprayed acoustic texture was standard on tract-built ceilings for two decades because it hid framing imperfections and absorbed sound cheaply. It also traps dust, yellows, crumbles when it is bumped, and cannot be cleaned or patched invisibly. Removing it flattens the ceiling plane, brightens the room by reflecting more light, and — on pre-1985 ceilings — retires an asbestos-containing material rather than leaving it overhead.
Acoustic texture sprayed before the mid-1980s can contain chrysotile asbestos in the binder. A sample the size of a coin goes to an accredited lab, and results usually come back in a couple of days. A negative result means the ceiling is scraped conventionally. A positive result means the removal is handed to a licensed abatement contractor working under containment and clearance testing, and we return afterwards to skim, texture and finish the exposed board.
Where a ceiling has been rained on from a failed valve or a roof leak, the texture is not the only problem. Paper facing swells, the board loses its bond to the joists, and skim coats applied over a stained surface bleed through the finish paint. Those areas are cut out and re-boarded, or sealed with a shellac-based stain blocker, before the skim coats go on.
Furniture is moved out or centred and wrapped, floors are covered, and the room is sealed behind plastic with taped-off supply and return vents. The texture is misted with water and left to soften, then scraped into the containment. Once the ceiling is bare, screw pops are reset, joints that have opened are re-taped, and the whole plane gets two skim coats of joint compound.
A scraped ceiling is not a finished ceiling. Every taped joint the original texture hid becomes visible under the flat light of a ceiling, which is why the surface gets skimmed edge to edge rather than spot-patched. Sanding is done with a pole sander on vacuum extraction, and the plane is checked with a work light held flat against it before any texture is sprayed.
If the adjoining rooms are staying acoustic, the new ceiling can be sprayed with an acoustic texture matched to the existing stipple. More often the ceiling is taken to a smooth Level 5, or given a light orange peel or knockdown that carries down onto the walls. Whichever way it goes, the texture is sprayed onto a sample board first and adjusted until it matches from a normal viewing distance.
Ceiling work is disruptive by nature, so the schedule is built around the household. Rooms are done one or two at a time, containment goes up in the morning and stays up until the sanding is finished, and air scrubbers run continuously inside the work zone. Debris is bagged inside the containment and carried out the same day rather than being staged in a hallway overnight.
Any acoustic ceiling sprayed before the mid-1980s gets sampled and lab tested before a scraper touches it.
Plastic walls, zippered doorways, taped-off vents and covered floors, so scrapings stay in the room they came from.
Wet scrape, two skim coats over the whole ceiling, sand, then a texture matched to the rest of the house or left flat.
Why homeowners call us
No scraping starts on a pre-1985 ceiling until the lab result is back. A positive result goes to a licensed abatement contractor and we return afterwards.
Air scrubbers run inside the containment for the length of the job so airborne dust does not migrate into the rest of the house.
The retexture is sprayed onto a scrap board and adjusted until it reads the same as the adjoining ceiling before it goes overhead.
FAQ
Two working days is typical: wet scrape and first skim coat on day one, second coat, sand and retexture on day two. Add a day if the ceiling has water staining that needs sealing before the skim coats.
Almost never. The work zone is sealed behind plastic with its own air scrubber, and the rest of the house stays usable. Bedrooms are usually scheduled one at a time so you always have somewhere to sleep.
Cost tracks ceiling area, ceiling height, whether asbestos testing comes back positive, and how much furniture has to be moved and masked. You get a fixed written figure after a walkthrough rather than a per-hour estimate.
Yes, and it is a common choice. A smooth ceiling needs a Level 5 skim over the full surface, because any lap or trowel edge shows once light rakes across a flat white ceiling.
Fixtures come down and go back up, and moulding is masked and cut free where the skim coat meets it. Anything brittle enough to be at risk is called out at the walkthrough before the job is booked.
