Our Process

  1. 1

    Emergency Assessment

    Upon arrival, we assess the extent of the sewage backup using thermal imaging and moisture mapping to identify all affected areas. This guides our tailored response plan and helps us understand water infiltration dynamics.

  2. 2

    Water Extraction

    Using specialized equipment, we remove standing water and moisture that has seeped into carpets, subfloors, or drywall. This process sets the stage for in-depth cleanup and reduces the risk of further property damage.

  3. 3

    Sanitization and Containment

    Containment barriers are set up to prevent contamination spread. Antimicrobial treatments are applied to all affected areas, ensuring thorough sanitation and reducing harmful pathogens.

  4. 4

    Structural Drying and Moisture Control

    Advanced dehumidifiers and air movers target moisture in structural components, restoring proper relative humidity to limit mold growth and protect materials. This includes safeguarding against wood wicking and subfloor issues.

  5. 5

    Documentation and Insurance Coordination

    We document the entire process, aiding the insurance claims with detailed moisture meter readings and drying logs. We liaise with your adjuster to ensure coverage alignment and maximize claim efficiency.

We Work With Your Insurance

Our crews document everything — photos, moisture readings, and a clear scope of work — in the format adjusters expect, and we communicate with your insurance company throughout the job. St. Louis homeowners always know what is happening and what their policy covers before work begins.
