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.

Fast to respond and easy to reach. The technicians were tidy, respectful of our home, and explained what caused the growth so it would not come back.

Local knowledge

Why Onset homes get mold

Onset homeowners know Massachusetts weather is hard on houses. Moisture finds its way into basements and crawl spaces across Plymouth County, and mold follows close behind.

It usually starts with water: a drip under a sink, humidity that never quite clears, or seepage after a storm. Given a few damp days, mold spreads across drywall, framing, and flooring.

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

  • Heavy rain and seasonal flooding pushing water toward foundations and crawl spaces
  • 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
  • Roof and plumbing leaks in Onset homes that feed hidden mold for months before anyone notices

If your Onset 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.
