The ring on the family room ceiling started the size of a coffee cup and is now wider than a dinner plate, with the paint lifting at the edge. The hall bathroom sits right above it, and the tub has been slow to drain for a year. Nothing ever showed upstairs. This site connects you by phone with an independent local provider who does mold removal in North Las Vegas and across Clark County.
Nothing comes down until the ceiling has been metered. A pin meter on the drywall and a non-invasive meter across the ceiling tell the crew how far the water spread between the joists, and in a two-story stucco house that is usually farther than the ring. They mark that edge, then go upstairs and meter the floor around the tub, the toilet, and the vanity to find which one is leaking.
Then containment goes up. Plastic seals the family room doorway, the return grille gets taped, and a HEPA air scrubber is ducted out a window so the room runs under negative pressure. Dust from the demolition stays inside the plastic instead of riding the attic air handler into the bedrooms.
Stop using that tub, toilet, and sink until a plumber has looked at them, and photograph the ring and the paint from below. Do not poke the ceiling or pull the bubbling paint; wet drywall sheds spores when it tears, and without containment they end up in the return.
Leave the air conditioning on and set the thermostat fan to auto. Skip the bleach. It wets the paper face of the drywall and leaves the growth in the gypsum. If the stain is on a first-floor wall instead of a ceiling, check the cabinet under the nearest sink and the floor behind the fridge for a wet spot.
Wet ceiling drywall and any insulation above it come out to a set distance past the meter line and go into bags inside the containment. The joists and the subfloor above stay if they read dry after cleaning. A subfloor that has been wet for months around a toilet flange sometimes has to be cut out and patched, and the crew tells you that before they do it.
After the demolition, every surface in the containment is HEPA vacuumed and wiped. Air movers and a dehumidifier run until the joists and the subfloor read dry, which after a long leak can take most of a week. If the smell comes from the attic equipment, see HVAC mold cleaning. If the growth started behind a vanity or under a shower pan, that is bathroom mold removal. Putting the ceiling and the paint back is mold damage repair.
The two-story houses built in Eldorado, Aliante, Valley Vista, and the Villages at Tule Springs since 1990 put two or three bathrooms over the living space, so a slow drain or a cracked fitting on the second floor shows up as a ceiling problem. In the 1950s to 1970s block houses around Downtown North Las Vegas and the Cheyenne corridor, the same call is a soft floor or a stained wall base over a slab line that has pinholed.
Nevada has no mold license. Removal is a trade the provider represents its own training in, and putting drywall and subfloor back is contractor work under the Nevada State Contractors Board. A rebuild that touches plumbing or electrical needs a permit from the City of North Las Vegas, Clark County, or the City of Las Vegas depending on where the house sits. Many Nevada policies pay for a sudden break and exclude a slow drip, so note the date you first saw the ring.
Have the address, which bathroom or line you suspect, and how long the ring has been growing. Say whether a plumber has already been out and whether anyone has painted over it. Call (725) 353-7567.
Standing byTell us which line, drain, or storm put the water there and which room shows growth or smells. The call goes to an independent local provider who handles mold removal and remediation across North Las Vegas, Sunrise Manor, and the north Las Vegas Valley.
A dark patch handled by where the water went, not what shade it is: containment first, porous material out, hard surfaces cleaned, the source fixed before closing.
A supply line that ran for weeks in a shut-up house, or storm water across the slab, mapped room by room and worked in zones as one project.
Coil, pan, drain line, and plenum cleaned when the attic air handler sweats through a North Las Vegas summer and the house smells sour at startup.
