Do this now: mold in an Indianapolis home

  1. Find and stop the water first, then dry the area. The EPA says wet materials dried within 24 to 48 hours usually will not grow mold.
  2. Do not run the HVAC system if you suspect it is contaminated with mold, the EPA says.
  3. Photograph the area and the leak before cleanup, and call your insurer if a sudden leak caused it.
  4. Under about 10 square feet, the EPA says you can usually clean it yourself; larger areas call for its professional remediation guidance.
  5. Renting? Report it to your landlord in writing and to the Marion County Public Health Department.
Definition

Mold removal in Indianapolis is cleanup and removal of mold growth plus the moisture source behind it; HomeAdvisor's 2026 national range is $1,223 to $3,757, about $10 to $25 a square foot.

Is it urgent? When mold needs a remediation company now

Mold covering more than about 10 square feet, or mold after a lot of water damage, calls for the EPA's professional remediation guidance. A musty smell with no visible source can mean hidden mold behind drywall, inside walls around pipes or inside ductwork, the EPA says. If the water is still coming in, start with an emergency plumber in Indianapolis. The CDC does not recommend testing to identify the type of mold; any visible growth should be removed.

Mold complaints in Marion County

Mold drove about half of housing complaints in Marion County in 2017. The Marion County Public Health Department told WRTV in 2017 that "about 50 percent of the calls we receive for housing-related issues are for mold." WRTV reported in 2020 that the department normally inspects non-emergency housing complaints within three days and can cite landlords for mold among other code violations. Tenants should report mold to the department and keep copies of every request to the landlord.

Why Indianapolis homes get mold

Most mold traces to a plumbing leak, a roof leak or a wet basement. Indianapolis's median home was built in 1973, and 59.2% of homes predate 1980, the Census Bureau's 2020 to 2024 survey shows, so many have original supply lines, drains and roofs. If a leak or sewer backup started the mold and you qualify, Citizens' Home Infrastructure Program repairs inside and outside water leaks and sewer or drain backups for owner-occupants under 70% of state median income (317-924-3311). Fix that first, or the mold returns. See roof repair in Indianapolis for roof leaks.

Selling an Indianapolis home with past mold

Indiana's seller disclosure form must cover known mold and moisture problems, the Environmental Law Institute's 2024 summary of state mold laws notes. Keep the remediation invoice and any clearance photos; buyers and their inspectors will ask.

Call your insurer too, photograph the damage before anything is moved, and do not sign an assignment of benefits or any contract that hands your claim to a contractor.
