What health symptoms are linked to indoor mold exposure?

Answered by Moe Bedard, founder of Mold Safe Solutions — San Diego's mold-only removal company

Short answer

Commonly reported symptoms include nasal congestion, coughing, wheezing, eye and throat irritation, headaches, skin irritation and fatigue, with stronger effects in people who have asthma, allergies or compromised immune systems.

The pattern that points at a building rather than a virus is symptoms that ease within a day or two away from home and return within hours of coming back.

We are inspectors, not physicians, and we do not diagnose. What we can do is tell you objectively whether the building has a moisture and mold problem, so your doctor is working from evidence rather than suspicion.

Why it matters in San Diego

Many San Diego families notice symptoms get worse during the marine-layer months (May Gray, June Gloom) or after winter rain, when indoor humidity spikes. Symptoms that ease when you leave the house are a clue.

How we handle it

We're mold removal experts, not doctors. Talk to your physician about symptoms. Our job is to find and remove the source. If your doctor wants data, optional lab testing gives a written report.

Signs it's time to call us

  • Congestion, sneezing, coughing or itchy eyes at home
  • Asthma that's worse indoors
  • Symptoms that improve when you're away
  • A musty smell in one room

Mistakes to avoid

  • Treating symptoms but ignoring a known leak
  • Using air fresheners to hide the smell
