Common Causes We See in St. Louis

  • High attic mold levels, due to insufficient ventilation, common in poorly insulated spaces
  • Crawl space mold, from rising basement humidity often aggravated by inadequate sealing
  • Bathroom mold growth, linked to inadequate ventilation, is frequent in areas with poor exhaust fans
  • Hidden leaks, causing mold behind your walls, typically from old or faulty plumbing systems
  • Stubborn condensation, on windows and doors, resulting from high indoor humidity levels
  • Faulty plumbing, leading to slow leaks, often disregarded until mold appears
  • Roof leaks, which introduce moisture into attics, particularly during heavy rainfall
  • Poorly sealed foundations, allowing moisture ingress, particularly in older homes
  • Flooding events, which can saturate household contents, creating conditions ripe for mold
  • Indoor plants, which can inadvertently increase local humidity levels if overwatered

While You Wait for the Crew

A few minutes of the right first moves can save thousands in damage. Here is what to do — and what not to do — before we reach St. Louis.

Do

  • Identify and resolve any active water leaks promptly to prevent further moisture intrusion
  • Increase ventilation to reduce moisture buildup, especially in frequently used areas
  • Vacuum floors with a HEPA filter vacuum to pick up spores without spreading them
  • Wipe down surfaces with mild detergent and water to reduce visible molds until professional help arrives
  • Keep affected areas as dry as possible using fans or dehumidifiers, avoiding excessive moisture

Don’t

  • Don’t use bleach to clean visible mold as it may worsen the situation by releasing additional spores
  • Avoid disturbing the mold, which can release spores into the air, increasing spread and health risk
  • Refrain from covering up mold with paint or sealants, which only masks the problem temporarily
  • Do not attempt major dehumidification or removal without professional guidance, as incorrect methods can exacerbate the problem

Our Process

  1. 1

    Initial Assessment

    We conduct a thorough inspection to identify all areas affected by mold and the source of moisture using both visual inspection and advanced tools like moisture meters. Air sampling may also be utilized to evaluate indoor air quality.

  2. 2

    Containment

    Using 6-mil plastic sheeting, we establish containment barriers to isolate impacted areas. Combined with negative air pressure machines, this prevents the spread of mold spores during remediation.

  3. 3

    Removal and Cleaning

    Materials contaminated with mold are removed and disposed of according to industry standards. HEPA vacuuming and antimicrobial treatments are employed to clean and sanitize all surfaces effectively.

  4. 4

    Drying and Dehumidification

    Through the use of industrial-grade dehumidifiers, we remove any lingering moisture. This step ensures mold does not return by maintaining indoor humidity at below 50 percent.

  5. 5

    Verification

    Once remediation is complete, post-remediation verification, including third-party clearance testing, confirms the complete removal of mold to established safe levels, ensuring your home is healthy and habitable.
