After 45 years helping Palos Verdes families buy, sell, and care for their homes, I’ve learned that a healthy house is just as important as a beautiful one. If you’re feeling under the weather and can’t quite pinpoint why, it’s worth asking a gentle but important question: could something about your home be contributing to your symptoms?
Below I’ll walk you through the most common household triggers I see in our coastal market, how to spot them, and simple, homeowner‑friendly steps to fix them. I’ve also included two real court‑proven cases where people became ill because of conditions in their homes—so you can see exactly how these issues play out in real life and why early attention matters.
Is Your Indoor Humidity in the “Comfort Zone”?
- Why it matters: Above about 60% relative humidity, moisture lingers and becomes a starter kit for mold. Below about 40%, air gets too dry and can irritate your airways.
Pick up an inexpensive hygrometer and aim for 40–60%. Run bath and kitchen exhausts during and 20–30 minutes after use, keep window sashes cracked when weather allows, and consider a dehumidifier in damp areas.
Real‑world case that fits this issue
- A California jury verdict in 2023 linked water intrusion and mold in a rental home to a tenant’s medical problems, awarding over $2 million for relocation, medical costs, and pain and suffering. The case turned on moisture that wasn’t addressed and mold that followed—classic “humidity too high” dynamics you can prevent with early detection and ventilation. Source: [Lawyers.com – Ghafouri v. Daftary (Cal. Super. 2023)](https://legal-info.lawyers.com/personal-injury/types-of-personal-injury-claims/filing-a-toxic-mold-lawsuit.html)
How to correct course fast:
- Ventilate while cooking/showering; set bathroom fans to a timer.
- Seal and repair roof, window, or plumbing leaks promptly.
- If indoor humidity won’t drop, add a dehumidifier or talk with an HVAC pro
about whole‑home solutions.
Excessive Dust: Small Particles, Big Irritation
- What happens: Dust collects pollen, outdoor pollutants, and can harbor dust mites. Result: irritated eyes, stuffy nose, sleep disruption, and immune stress—especially for those with allergies or asthma.
- What to do:
- Vacuum with a sealed HEPA unit 2–3 times/week; empty the bin outside.
- Add a high‑MERV or HEPA media filter to your HVAC and change it on schedule.
- Wash bedding weekly in hot water; don’t forget drapes and plush items.
- Adopt a no‑shoes‑indoors routine to keep outdoor contaminants outside.
Heating and Cooling Systems: Comfort…or a Hidden Moisture Source?
- Problem pattern I see: An A/C that cools well but leaves condensation in ducts or air handlers can seed mold growth. That growth then circulates through the house and can trigger coughing, headaches, allergies, and asthma flare‑ups.
- Maintenance rhythm:
- Service HVAC seasonally; keep condensate drains clear.
- Clean or replace
filters regularly; consider duct inspection/cleaning every few years, especially after leaks or construction.
- Keep supply and return vents unblocked for good airflow.
Real‑world case aligned with HVAC/moisture
- In Alabama, condo owners developed significant respiratory problems—migraine strokes, pneumonia, and breathing issues—after mold exposure traced to building moisture issues; a court awarded $600,000, including medical and relocation costs. Proper ventilation and moisture management would likely have prevented the health fallout. Source: [Lawyers.com – McClellan v. Holiday Isle Owners Ass’n (Ala. Cir. Ct. 2021)](https://legal-info.lawyers.com/personal-injury/types-of-personal-injury-claims/filing-a-toxic-mold-lawsuit.html)
Damp Areas: Basements, Bathrooms, and “That One Closet”
- Why Palos Verdes owners should care: Our coastal microclimate and marine layers can keep materials damp longer. Basements, under‑stairs closets, and behind‑tile areas are frequent hot spots.
- Simple checks:
- Make sure gutters and downspouts carry water far from the foundation.
- Inspect caulking, supply lines, traps, and shut‑offs; fix drips early.
- Watch for “musty” odors—your nose often finds problems before your eyes.
- Keep an eye on that hygrometer; a sudden bump is a clue.
Ventilation: Tight Is Energy‑Smart—But Air Still Needs to Move
- Balanced approach:
- Open windows when the weather behaves.
- Use range hoods and bath fans that vent outdoors.
- In stuffy homes, ask your HVAC pro about an energy‑recovery ventilator (ERV) to bring in fresh air without losing comfort.
Toxic or Irritating Household Products
- Where they hide: Carpets, manufactured wood, some upholstery foams, and certain cleaning supplies can off‑gas or contribute to indoor air irritation.
- What to do:
- Choose low‑ or zero‑VOC paints and adhesives.
- Read labels on cleaners; avoid mixing chemicals and keep lids tight.
- When replacing floors or cabinets, ask about formaldehyde‑free and low‑emission options; ventilate well during and after installations.
Putting It All Together: A Veteran Realtor’s Healthy‑Home Checklist
- Measure: Hygrometer in main living area and lowest level; target 40–60%.
- Move air: Exhaust fans for cooking/bathing, windows as weather allows.
- Maintain: Seasonal HVAC service; change filters; clear condensate drains.
- Monitor moisture: Fix roof/window/plumbing leaks fast; keep gutters flowing away from the house.
- Manage dust: HEPA vacuuming; washable doormats; no shoes inside.
- Mind materials: Favor low‑VOC finishes and smart, breathable building products.
Why I Share These Stories
I’m not here to alarm you—only to guide you. Over the decades, I’ve seen families feel “off” for months until a modest fix brought relief. I’ve also seen delays escalate into major health and financial headaches. The two cases above show courts recognizing a clear connection between home conditions and illness when moisture and ventilation issues weren’t addressed. Acting early is almost always easier and cheaper.
If you’re noticing persistent symptoms at home—especially headaches, sinus issues, coughing, or worsening asthma—start with humidity and ventilation. If you need referrals to reputable local inspectors, remediators, or HVAC pros who understand our Palos Verdes climate and construction styles, I’m happy to connect you.
