Most homeowners have never hired a mold company before, so it is hard to know what a proper job looks like or how to compare estimates. This guide walks through the process we follow on residential mold jobs in Marietta and across Cobb County, based on the IICRC S520 standard for professional mold remediation.

Step 1: Inspection and Moisture Mapping

Mold is a moisture problem first. We use moisture meters and thermal imaging to find where water is coming from and how far it has spread behind walls, under floors and in cabinets. Where it makes sense, we recommend independent air or surface testing so you have an unbiased baseline. You get photos and a written scope, not a guess.

Step 2: Stop the Water Source

A leaking supply line, a failed shower pan, a roof flashing gap, poor crawl space drainage. If the source is not fixed, the mold comes back. Because we also do full remodeling, we can repair the cause instead of sending you to find another trade.

Step 3: Containment and Air Filtration

We seal the work area with plastic sheeting and zipper doors and run HEPA air scrubbers under negative pressure. This keeps spores from traveling to clean rooms while materials are being removed. Your HVAC in that zone is shut down or isolated during the work.

Step 4: Removal and Cleaning

Porous materials with mold growth, like drywall, insulation and carpet pad, are cut out and bagged. Framing and other structural materials are HEPA-vacuumed, cleaned and treated. The goal is physical removal of the growth, not just killing it or painting over it.

Step 5: Drying and Verification

Dehumidifiers and air movers bring the structure back to normal moisture levels, and we document the readings. When requested, a third-party clearance test confirms the area is ready before anything is closed up.

Step 6: Rebuild

This is where many mold companies hand you off. We put the room back together: drywall, paint, flooring, cabinets, tile, even a full bathroom or kitchen remodel if you want to upgrade while the walls are open. One company, one schedule, one point of contact.

5 Questions to Ask Any Mold Company

Are you IICRC certified and insured?
How will you find and fix the moisture source?
What containment and air filtration will you use?
Is the rebuild included, or will I need another contractor?
Will you document the job for my insurance claim?
