We had a mold issue in a back office after a roof leak and needed it handled without shutting down the whole space. The crew worked around our hours and kept the rest of the building operating while they contained and cleared the problem area.

We had mold after a slow leak under the sink. They inspected it, explained the plan, and left the space dry and clean.

Professional containment, HEPA vacuuming, the whole process was textbook. Worth hiring certified pros.

Local knowledge

Commercial Mold Remediation for St. Louis, MO homes

Commercial Mold Remediation in St. Louis tends to start the same way mold does across City of Saint Louis: heavy rain and seasonal flooding pushing water toward foundations and crawl spaces. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from Hillsdale, University City, Pine Lawn and the rest of St. Louis call us.

We handle commercial mold remediation for St. Louis the right way. We find and fix the moisture source first, because mold always returns if the water problem is left behind, then we contain the area and remove the mold safely.

Our team is based in Valley Park, about 30 minutes from our Valley Park base, so we can usually reach a St. Louis home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.
