What People Mean by Black Mold

Black mold usually means Stachybotrys, a dark green to black mold that grows on drywall, wood and paper that stayed wet for a long time. Plenty of other molds look black too. You cannot tell which one you have by its color, and the CDC advises treating every mold growth the same way, by removing it and fixing the water problem.

Where We Find It in Las Vegas Homes

The valley is dry, so mold here almost always means a leak. We find it most in AC air handler closets where the condensate line backs up, inside sink cabinets after a slow drip, behind washers and refrigerators, around water heaters and in walls below an upstairs bathroom. Swamp coolers and attic AC drain lines add more.

How We Remove It

  • Find the moisture source with meters and thermal imaging, and get it fixed.
  • Seal the area with plastic containment and run HEPA air scrubbers so spores stay put.
  • Remove mold damaged drywall, insulation and materials that cannot be cleaned.
  • Clean and treat what stays with 100% organic products.
  • Dry everything to normal readings, then rebuild with our own crew.

Can You Clean It Yourself?

The U.S. EPA says a small patch, under about 10 square feet, is often a do it yourself job if the water problem is fixed. Anything bigger, anything inside a wall or the AC system, or mold in a home with someone who has asthma or a weak immune system is worth a professional. Bleach on drywall does not reach the roots and the stain often comes back.

Questions

Black Mold Questions

Is black mold dangerous?

Any mold can cause allergy symptoms, coughing and asthma flare ups, especially for children, older adults and anyone with a weak immune system. The color does not tell you how risky it is. What matters is how much there is and fixing the leak.

Do I need a mold test first?

Not always. If you can see it and smell it, the plan is the same. Testing helps when you smell mold but cannot find it, or when you need a report for a landlord, a sale or an insurer. See our mold inspection page.

Does insurance cover black mold removal?

Often only when the mold comes from a sudden covered leak, like a burst pipe. Mold from a long slow leak or humidity is usually excluded. We document the source for your adjuster either way.
