Assessed First
Mold Removal & Remediation in University City, MO
Containment, HEPA filtration, and antimicrobial treatment eliminate mold colonies at the source and prevent cross-contamination throughout the property. Mold remediation removes affected porous materials and corrects the moisture source that allowed growth. The work is done under containment with HEPA filtration so spores are not carried into unaffected rooms, and the area is cleared only once the underlying moisture problem has been resolved.
No obligation: the assessment comes before any scope
Remediation is the step after the assessment, not before it. A local pro establishes how far the growth extends and what is feeding it, because removing what is visible while the moisture source is still running puts the same colony back in the same wall. Texas and several other states also set a square-footage point above which the work has to be done by a licensed remediator — the service note below covers where that line falls in this city.
Often needed alongside
- Mold Inspection & Testing
An assessor determines whether mold is present, identifies where it is growing, and measures how far it has spread — before any remediation quote is issued.
- Sewage & Contaminated Water Cleanup
Category 3 black-water losses are handled with full PPE, biohazard disposal, and professional disinfection to restore safe conditions.
Frequently asked questions
The sewer is separate, not combined. Why does May still wet the basement?
Because the path is the masonry and the openings, not a surcharged main. These houses were built with areaways and coal chutes at grade, and a 4.9 inch May fills those openings. Limestone joints under the lot add a second path at the footing. A separate sewer keeps sewage out of the floor drain. It does nothing for a chute that is sitting in a puddle. Cover the openings and trace the limestone; do not assume a modern main solved 1949.
The sidewalk is higher than it used to be and water sits at the areaway. Is that the city's fault?
It is the grade. Decades of sidewalk and alley raising have flattened or reversed the fall the mason set, so roof water that used to leave now stops at the areaway. Whether the raise was public or private, the water does not care. Restoring fall to the alley or adding a drain at the areaway puts May rain back on a path that exists. The brick is not newly porous; the lot is newly flat.
A rubble wall weeps after May even when the chute is closed. Where is that moisture coming from?
The stone itself. Rubble laid without a damp course takes perched water from limestone joints, and a closed chute only stops the splash path. May rain that entered the rock still shows as a wet line along the footing. Exterior drainage at that wall, and keeping roof water off the uphill side, is the remaining work. The chute was one inlet. The rubble is the other.
