Mold & Indoor Air Quality

Mold Exposure and the High Cost of Neglect

Indoor air should be safe. But when mold growth, water damage, or ventilation failures contaminate a home, workplace, school, or care facility, the results can be devastating, especially for children, older adults, and anyone with underlying respiratory or immune conditions.

McEldrew Purtell represents individuals and families in catastrophic injury and wrongful death claims involving toxic exposure from mold and other indoor air hazards. We focus on accountability: who knew, who ignored it, and what it cost.

When Mold Exposure Becomes a Catastrophic Injury Case

Mold isn’t always visible. It can thrive behind walls, above ceiling tiles, under flooring, inside HVAC systems, and in damp basements or crawlspaces. Ongoing exposure may contribute to serious conditions, including:

  • Severe asthma attacks and permanent worsening of respiratory disease
  • Hypersensitivity pneumonitis and chronic lung inflammation
  • Serious infections in immunocompromised individuals
  • Neurological symptoms that disrupt daily function (in some cases)
  • Complications that lead to hospitalization, long-term disability, or death

If a property owner, employer, contractor, or facility had the ability and legal duty to correct known moisture or ventilation problems but failed to act, the consequences can be actionable.

Not Just a “Maintenance Issue”

Mold and indoor air quality cases often come down to preventable failures, such as:

Water intrusion that wasn’t fixed


Roof leaks, plumbing failures, flooding, and foundation seepage that were patched over or ignored.

Improper remediation


“Cleanups” that spread contamination, fail to remove damaged materials, or don’t address the moisture source.

HVAC and ventilation problems


Poor filtration, negative pressure issues, blocked fresh-air intake, or contaminated ductwork.

Building design or construction defects


Materials and systems that trap moisture or allow chronic condensation.

Institutional neglect


Conditions in schools, hospitals, nursing homes, or public housing that persist despite complaints, reports, or prior incidents.

Ignored warnings and complaints


Maintenance requests, tenant reports, employee complaints, or internal inspection findings that flagged moisture, mold, or air quality problems—but were dismissed, delayed, or deliberately minimized until serious harm occurred.

Where These Exposures Happen

We investigate serious injury and wrongful death claims tied to mold and indoor air hazards in places like:

  • Apartment buildings and rental properties
  • Hotels and short-term rentals
  • Schools and daycare centers
  • Offices and industrial workplaces
  • Hospitals, rehab facilities, and nursing homes
  • Public buildings and government facilities

Who May Be Responsible

Depending on the facts, liability may involve:

  • Landlords and property managers
  • Employers and building owners
  • General contractors and remediation companies
  • Engineers, architects, or developers
  • Maintenance vendors and HVAC contractors
  • Government agencies or housing authorities

We look for the paper trail—inspection records, complaint logs, work orders, remediation invoices, air sampling, moisture mapping, and the timeline that shows what was known and when.

How we build Mold and IAQ Cases

These cases aren’t won with assumptions. They’re won with evidence.

Our approach typically includes:

  • Rapid preservation of building conditions and documentation
  • Investigation into moisture sources and repair histories
  • Coordination with qualified experts when needed (industrial hygiene, building science, medical causation)
  • A clear damages story that connects exposure to real-world harm, medical crisis, disability, lost income, and the family’s losses in a wrongful death claim

Signs a Mold/Indoor Air Case May Be More Serious Than You’ve Been Told

You may want legal guidance if:

  • Symptoms escalated after moving into a building or returning after “repairs”
  • Multiple occupants became ill in the same environment
  • There’s a history of leaks, flooding, or recurring water damage
  • Management dismissed complaints or discouraged testing
  • A vulnerable person suffered hospitalization, respiratory failure, or fatal complications

Talk to a Toxic Tort Team That Investigates the “Why”

If mold exposure or dangerous indoor air contributed to a severe injury, or you lost a loved one after prolonged exposure, your family deserves a serious investigation, not a brush-off.
