When a sump pump fails, water can fill a basement in no time. That's what happened to a homeowner in Saint Louis, and our team at ABC Environmental Contracting Services stepped in fast. This sump pump water damage job involved a flooded finished basement, and we handled everything from water removal to sanitizing the space. See how we handled expert-level water mitigation in St. Louis to get this home back on track.

What Happened: Melting Snow and a Failed Sump Pump



After heavy snow melted, the sump pump gave out, flooding the basement of this two-story home. The affected areas included a carpeted living room and home office. The drywall and baseboards were soaked, and water had seeped under the flooring. While the pump was repaired, the damage needed professional mitigation.


How We Handled the Water Damage



Here's a step-by-step look at how our team responded to the water damage and got the basement back to a clean, dry, and safe condition.


Inspection and Moisture Mapping


We arrived quickly to assess the space. Using moisture meters and thermal imaging, we identified all wet areas, including hidden spots behind drywall. 


Water Extraction and Demo


We removed all standing water using high-powered extractors to stop any further damage and speed up the drying process. Once the water was out, we carefully removed the saturated carpet and padding, which couldn't be salvaged due to prolonged exposure. Any materials that showed signs of swelling, separation, or mold risk were also taken out. We performed flood cuts on the affected drywall to remove soaked portions and allow air to circulate inside the wall cavities. Damaged baseboards were also removed to prepare the space for a full and proper rebuild.


Drying, Sanitizing, and HEPA Vacuuming


To make sure the basement was completely clean and safe, we followed a detailed process:

  • Dehumidification and Air Movement: We placed commercial-grade dehumidifiers and air movers throughout the space to fully dry out walls, floors, and framing.
  • HEPA Vacuuming: All exposed surfaces were thoroughly vacuumed using HEPA-filtered equipment to remove fine particles, allergens, and contaminants.
  • Sanitizing: We applied EPA-approved disinfectants to all affected areas to kill bacteria and help prevent mold growth.


Why Fast Action Matters After Sump Pump Water Damage


Responding quickly to sump pump water damage can prevent long-term structural problems and mold. In this case, our fast response helped minimize the impact and get the basement ready for repairs without delay.
