What's included
What Basement Sanitization and Disinfection Includes
Every job includes a full assessment, water removal, cleaning, disinfection, and verification. We also handle debris removal and provide documentation for insurance. Add-ons like drywall repair or content pack-out are available if needed.
Water Extraction
We remove all standing water using truck-mounted extractors and submersible pumps. For sewage backups, we use dedicated equipment. Extraction usually takes 2 to 4 hours for a typical basement.
Surface Cleaning
We scrub all affected surfaces with EPA-registered cleaners. This removes soil, biofilm, and debris that harbor bacteria and mold. We clean concrete, block, wood, tile, and salvageable contents.
Hospital-Grade Disinfection
We apply EPA-registered disinfectants using foggers and sprayers. Contact time runs 10 to 15 minutes per application. For sewage jobs, we apply two rounds to ensure complete kill.
Drying and Verification
We run air movers and dehumidifiers until moisture readings return to normal. We re-test and provide a written report. Most jobs dry in one to two days.
Debris Removal
We bag and haul away all removed materials, including carpet, drywall, and insulation. We dispose of sewage-contaminated waste according to Maryland regulations.
How it works
Our Basement Sanitization Process
A certified technician inspects the entire basement using moisture meters and thermal imaging cameras. We map the water damage, identify the source, and test for mold and bacteria. You get a written scope and a flat price before we start. This takes 30 to 45 minutes for most Annapolis homes.
We extract standing water with truck-mounted extractors and submersible pumps. For sewage backups, we use dedicated equipment that never touches clean-water jobs. A typical 1,000-square-foot basement takes 2 to 4 hours to extract. We haul away any saturated debris that cannot be saved.
Every surface gets scrubbed with EPA-registered cleaners. We use wet/dry vacuums and hand tools on concrete, block, wood, and tile. Porous materials like soaked carpet and drywall get removed and bagged. This step removes the physical soil that harbors bacteria and mold.
We apply hospital-grade disinfectants using foggers and sprayers. The solution reaches into cracks, corners, and the underside of stairs. We treat joists, subfloor, walls, and any salvageable contents. Contact time runs 10 to 15 minutes per application. For sewage jobs, we apply two rounds.
After disinfection, we run air movers and dehumidifiers to dry the space completely. We re-test moisture levels and take surface samples when needed. You get a written report showing the basement is dry and sanitized. Most jobs finish in one to two days.

Tools & methods
Tools and Methods We Use
Thermal Imaging Cameras
We use thermal cameras to find hidden moisture behind walls and under floors. This helps us target sanitization where it matters most.
Moisture Meters
We test moisture levels before, during, and after drying. This confirms the basement is dry and ready for final verification.
Truck-Mounted Water Extractors
These powerful machines remove hundreds of gallons of water fast. They cut drying time and reduce mold risk.
Dri-Eaz and Phoenix Dehumidifiers
We use commercial-grade dehumidifiers to pull moisture from the air and materials. These units dry basements faster than consumer models.
EPA-Registered Disinfectants
We apply hospital-grade disinfectants that kill bacteria, viruses, and mold on contact. We follow label directions for dilution and contact time.
Hydroxyl Generators
These machines neutralize odors and kill airborne pathogens. They are safe for occupied spaces and leave no chemical residue.
