If you see mold right now

Three things to do while you wait

Stop the moisture

Shut off any active leak and wipe up standing water. Mold needs moisture to spread, so cutting the water source first slows it down.

Keep the area closed

Avoid disturbing or scrubbing heavy growth. Close doors to the room so spores are not spread through the rest of the home.

Call our 24/7 line

Reach our team any hour at (844) 352-3560. We will talk you through the next steps and set a same-day visit when needed.

Called about a musty smell and they walked me through every step before starting. The area was contained properly and the odor was gone when they finished.

Our Valley Park home had mold in the basement after heavy rain. They fixed it fast and it has stayed dry.

Local knowledge

Why Florissant homes get mold

Homes in Florissant face the same Missouri moisture that drives mold across Saint Louis County: humid stretches, damp lower levels, and the occasional leak that goes unnoticed for weeks.

The trigger is almost always moisture, whether from condensation, a hidden leak, or groundwater after a wet spell. Left alone, mold moves from one damp surface to the next.

Whatever the size, we contain the work area, remove the growth to the IICRC S520 standard, and leave the space in Florissant dry and rechecked.

  • Plumbing leaks and poor ventilation that let damp air linger and mold spread
  • Humid seasons that keep indoor moisture high for weeks at a time
  • Air conditioning condensation feeding mold on cool basement and closet walls
  • Crawl spaces and sump pumps around Florissant that struggle to keep up during wet spells

If your Florissant home has a radon mitigation system, the fans and pipes often sit right where basement mold begins. We work carefully around them so we clear the mold without disturbing your setup.

Whatever started it, we find the moisture source first, because mold always returns if the water problem is left behind. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.
