If you have found mold in your home, the first question is: how much is this going to cost? Getting a real answer before you call anyone puts you in a much stronger position. Here is an honest local pricing breakdown for mold remediation in Marietta, Smyrna, Kennesaw, and all of Cobb County.

Mold Remediation Cost by Job Type in Cobb County (2026)

Bathroom mold (small area): $500 to $1,500. Covers containment, removal of affected drywall or grout, antimicrobial treatment, and air scrubbing. Common cause: poor ventilation or a slow leak behind the wall.

Crawl space mold: $1,500 to $4,000. Crawl spaces in Georgia trap humidity year-round and mold here often goes undetected for months. May include encapsulation and vapor barrier replacement.

Basement mold: $2,000 to $8,000. The most extensive type, often involving foundation moisture, multiple materials, and structural components. Georgia clay soil and drainage issues make this common in Cobb County.

HVAC and duct mold: $1,000 to $3,500. Mold inside ductwork circulates spores through every room. Includes full duct cleaning, antimicrobial fogging, and air handler inspection.

Attic mold: $1,500 to $5,000. Almost always caused by inadequate ventilation or a roof leak. Includes HEPA vacuuming, wire brushing of rafters, antimicrobial treatment, and sealing the moisture source.

Whole-house or multi-room mold: $5,000 to $15,000 and up. Large-scale infestations that have spread through multiple rooms or into structural framing require full containment, selective demolition, and complete reconstruction.

Why a Phone Quote Means Nothing

Any company that gives you a firm price without inspecting your home has not seen enough mold. A bathroom that looks like a $700 job can open into $4,000 of wall cavity mold once the drywall comes down. A legitimate company always does an on-site assessment first. We do ours free of charge.

Does Homeowner Insurance Cover Mold in Georgia?

Yes, under the right conditions. Georgia homeowner policies typically cover mold remediation when the mold came from a sudden accidental event: a burst pipe, appliance failure, or storm damage. Mold from a slow leak that was ignored is typically denied. Many Georgia policies also cap mold coverage at $5,000 to $10,000, so ask your insurer about the cap before work begins.

House of Remodeling is Xactimate certified, the same software insurance adjusters use. We document your damage thoroughly, prepare estimates in the format your insurer needs, and communicate directly with your adjuster to maximize your covered scope.

What to Demand from Any Mold Company You Hire

Before hiring anyone in Cobb County for mold work, confirm: IICRC certification, a written itemized estimate breaking down containment, removal, treatment, disposal, and post-testing, proof of liability insurance, and verifiable local reviews. Never hire a company that skips finding the moisture source. Without fixing the source, the mold returns within weeks.
