Square Footage and Depth of Contamination
The biggest cost driver is how much floor area was affected and how deep the water sat — a half-inch in one bathroom is a very different job than several inches spread across a finished basement.
How Long the Water Sat Before Cleanup Began
Category 3 water that sits for hours does more damage than water addressed immediately — it soaks deeper into flooring, subfloor, and drywall, which can mean more material needs to be removed rather than dried and disinfected in place.
What Materials Were Affected
Porous materials — carpet, carpet pad, drywall, some subflooring — typically cannot be safely disinfected after Category 3 contamination and need to be removed and disposed of properly. Non-porous surfaces like tile and sealed concrete can often be cleaned and disinfected in place, which costs less.
Whether the Source Has Been Cleared
If the backup was caused by a clogged or damaged sewer line, that line typically needs to be cleared or repaired — sometimes by a plumber we coordinate with — or the same backup will happen again. That coordination can be part of the overall project cost.
Disinfection and Odor Treatment
Category 3 cleanup always includes antimicrobial treatment and odor control, not just extraction and drying. The scope of disinfection scales with the affected area and materials involved.
Whether Post-Cleanup Verification Is Needed
For larger jobs, air quality or surface verification after cleanup may be recommended to confirm the space is safe, which is a separate line item from the cleanup itself.
The Only Way to Get an Accurate Number
Because these variables differ job to job, we don't publish a flat rate — anyone quoting a number without seeing the damage is guessing. Call our 24/7 line, describe what happened and how large the affected area is, and we'll give you a realistic estimate and dispatch a crew.
