Mold and health — at a glance
- Most people: cold-like symptoms with chronic exposure — stuffy nose, cough, watery eyes, skin irritation.
- Allergy-prone people: stronger allergic reactions — sneezing, wheezing, worsening asthma.
- Immunocompromised or lung disease: higher infection risk from mold spores. Consult a doctor if symptoms persist.
- Infants, elderly, pregnant: extra caution — don’t wait on mold work in those households.
- This page is not medical advice. If symptoms persist, see a doctor. Vault handles the mold removal; your doctor handles the diagnosis.
- Suspect hidden mold? $349 air sampling + lab analysis. (385) 250-2825.
What the EPA and CDC say
Both agencies agree on the basics: mold is everywhere, but concentrated indoor mold growth can cause health problems. Nasal congestion, throat irritation, cough, eye irritation, and skin irritation are the most commonly reported symptoms. People with mold allergies, asthma, or weakened immune systems may react more strongly.
Neither agency recommends routine mold testing for “health” purposes alone — the fix is the same regardless of species: find the moisture source, remove the growth, and prevent recurrence.
Common symptoms linked to indoor mold
- Nasal and sinus congestion that doesn’t track with pollen season.
- Cough or wheezing that improves when you leave the house.
- Red, watery, itchy eyes.
- Skin irritation or rash.
- Headaches and fatigue in a specific room or basement.
- Worsening asthma symptoms.
The “improves when you leave” test is informative. If symptoms consistently ease away from home and return within hours of coming back, indoor air quality is the first thing to check.
Who should be extra cautious
- Infants and small children — developing lungs are more reactive.
- Elderly adults — immune and respiratory reserves are smaller.
- Pregnant women — avoid DIY mold remediation; call a pro.
- Asthma, COPD, or allergies — mold is a known trigger.
- Immunocompromised — chemotherapy, transplant, HIV, autoimmune — some molds (Aspergillus, Fusarium) can cause serious infection.
If anyone in these groups lives in the home, don’t wait to see if the mold “gets worse.” Call for an inspection.
The “black mold” question
Stachybotrys chartarum is what people mean by “toxic black mold.” It’s one of several molds that can produce mycotoxins under certain conditions. It’s also not the only black-colored mold, and most black mold found in Utah homes is Cladosporium or Alternaria, which are less concerning but still shouldn’t be living on your drywall.
Point: you cannot identify the species by looking at it. If you’re worried enough to care which species it is, that’s enough reason to have air samples analyzed. Vault’s $349 inspection tier includes lab-analyzed air samples through Sporecyte lab.
What to do if you think you have a mold problem
- Don’t disturb visible growth. Sweeping, wiping, or spraying bleach on mold can release spores and make the problem worse. Stop the moisture source first.
- Ventilate and limit exposure. Close doors to affected rooms if possible. Keep immunocompromised residents away.
- Document. Photos of visible growth, the water source if you can identify it, and any health symptoms you’ve noticed.
- Call Vault at (385) 250-2825. We’ll walk you through what to do before the inspection, and schedule based on urgency.
- See your doctor about symptoms. Mold-related health work-up is their job — ours is making sure the mold is gone.
