Local knowledge

Mold Clearance Testing for St. Louis, MO homes

Mold Clearance Testing in St. Louis tends to start the same way mold does across City of Saint Louis: humid seasons that keep indoor moisture high for extended periods. 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 pick up the phone.

Mold clearance testing for St. Louis is handled the right way. The technicians find and fix the moisture source first, because mold always returns if the water problem is left behind, then the area is contained and the mold is removed safely.

St. Louis is about 17 miles from Valley Park, so a crew can usually be there the same day you call. The methods follow public guidance from the EPA and the CDC on handling indoor mold safely.

St. Louis specifics

Mold Clearance Testing in St. Louis: what actually causes it

For a home in this area, mold clearance testing starts with finding the moisture, because the water is what feeds the mold. What sets Mold Clearance Testing apart is where it hides: the areas that were just remediated, exactly where homeowners rarely look. The technicians handle Mold Clearance Testing for homes from Mehlville to Hillsdale and the surrounding area the same careful way. Mold Clearance Testing is one of the more common calls homeowners around St. Louis make.

By the time a family calls about Mold Clearance Testing, they have usually already seen a musty smell or a spreading stain. The reason Mold Clearance Testing comes up so often here is simple: heavy rain and seasonal flooding pushing water toward foundations and crawl spaces, month after month, in home after home. Mold Clearance Testing is kept contained and tidy, so the rest of the home near Hillsdale stays livable while the work runs. A St. Louis home that needs Mold Clearance Testing almost always has a moisture story behind it, and it usually starts with older St. Louis architecture with finished basements and lower ventilation.

Here is how Mold Clearance Testing usually goes:

  • Remove moldy material to the IICRC S520 standard
  • Inspect the affected area and find the moisture feeding the mold
  • Recheck the space and document the work for your records
  • Dry the structure with commercial equipment until readings normalize
  • Contain the space under negative air with HEPA filtration
