I hired RemediationX to remediate mold growth in my commercial property in Las Vegas. They started with a thorough inspection and testing to determine the extent of contamination. The team provided a structured plan including containment, removal, cleaning, and verification of air quality. Updates were given throughout, and the worksite was kept organized. The property is now safe and free of mold concerns.

Summerlin South, Nevada
Mold Remediation in Summerlin South, NV
In Summerlin South, mold usually starts after a leak nobody saw. A slow drip under an upstairs sink, an attic AC pan or wet soil against a stucco wall keeps one spot damp long enough.
We find mold in Summerlin South homes, remove it under containment and treat the area with 100% organic products.
At a Glance
- Mold here grows from hidden leaks, not from the dry air.
- Plastic walls and HEPA air scrubbers protect the rooms around the work.
- We fix the moisture source so the mold has nothing to feed on.
- Mold can trigger allergies and breathing trouble.
After the Ceiling Looks Dry
Upstairs leaks are common in Summerlin South two story homes, and the ceiling below often gets patched and painted once it looks dry. But the insulation and joists above that patch may still hold water. In a closed space with no air moving, mold can grow there for weeks. A musty smell in a downstairs room or dark spots showing through fresh paint are the usual signs. We check the ceiling cavity with moisture meters before we cut. Then we remove the wet material behind plastic containment so spores stay out of the rest of the house. New drywall and paint go up only after the space tests dry.

Stucco Walls Next to Wet Planter Beds
Summerlin South yards often have planters and grass right up against the house, and sprinklers run all through the hot months. Stucco is not waterproof. When the soil at the base of a wall stays wet, water wicks up behind the stucco and into the bottom of the wall framing. Mold then grows on the back of the baseboard and drywall inside. You may see it first in a closet on an outside wall. We open the wall, remove moldy drywall and insulation, clean the framing and treat it with 100% organic products. Moving sprinkler heads away from the wall helps keep it from coming back. So does keeping soil a few inches below the stucco line.
Guest Baths and Casitas That Sit Unused
Larger Summerlin South homes, especially in The Ridges, often have a guest bath, a casita or a wet bar that nobody uses for weeks. A slow leak under that sink or behind that toilet can run with nobody there to notice. By the time someone opens the door, the cabinet floor is soft and mold covers the back wall. Mold can trigger allergies and breathing trouble, so we run HEPA air scrubbers while we work. After the mold is out and the area is dry, we rebuild the cabinet, wall or floor ourselves. You do not need a second company to finish the job.

Questions
Asked in Summerlin South
Why did mold show up after my Summerlin South ceiling was repaired?
The surface dried, but the wet insulation and framing above it did not. With no air moving in that space, mold had time to grow. We measure moisture inside the cavity, remove what is moldy and dry the rest before it is closed up.
Can my sprinklers cause mold inside my Summerlin South house?
They can. When sprinklers keep the soil against a stucco wall wet, water can wick up into the base of the wall. Mold then grows on the inside where you cannot see it. Keep water off the wall and watch for musty closets on that side.
Do you treat mold in Siena and The Ridges?
Yes, in every Summerlin South community. We use 100% organic treatments, contain the work area and run HEPA air scrubbers. We are an IICRC certified firm, #261729, and we can rebuild what we remove.
