At Ness Restoration & Remediation Inc., we’ve seen a noticeable increase in calls from Boise, Nampa and Caldwell homeowners worried about musty crawl spaces, allergy symptoms and possible mold behind walls or under floors.

In this article, we’ll explain why mold has become such a major topic in 2025 and what you can do to protect your home and your family’s health.

Treasure Valley Homeowners Are More Concerned About Mold and Air Quality Than Ever Before

1. Modern Homes Are Built Tighter, Which Traps Moisture

Today’s homes are designed to be more energy-efficient. That’s good news for utility bills, but it can be bad news for ventilation.

Airtight construction can trap humidity from everyday activities like:

• Showers and baths
• Cooking and boiling water
• Running humidifiers
• Drying clothes indoors

When warm, moist air can’t escape, it often ends up condensing on cooler surfaces — inside walls, in crawl spaces or on window frames.

Over time, that moisture can create the perfect environment for mold to grow.

2. More People Work From Home and Notice Problems Sooner

Since 2020, more Treasure Valley homeowners are working from home at least part of the week. That means people are spending more hours inside their living spaces and noticing things they may have ignored before, such as:

• Musty or “earthy” smells, especially in certain rooms or near the crawl space
• Condensation forming on windows in the morning
• Allergy or asthma symptoms that seem worse at home
• Doors that swell or stick when humidity is high

These small signs can sometimes point to hidden moisture problems that, if left alone, may turn into active mold growth.

3. Social Media Has Raised Awareness About Mold and Indoor Air Quality

Mold is a popular topic on TikTok, Instagram and other social platforms. From “mold horror stories” in rentals to DIY testing kits and before-and-after remediation videos, homeowners are seeing real examples of how serious mold can become when it’s ignored.

This constant exposure has made people more aware of mold risks and more likely to ask, “Could that be happening in my home?” As a result, Ness Restoration has seen a rise in calls from homeowners looking for professional inspections
and honest answers.

4. Idaho’s Dry Climate Doesn’t Always Prevent Mold

Many Idaho homeowners assume the dry climate will protect them from mold, but that isn’t always the case. We frequently find mold in:

• Poorly ventilated crawl spaces
• Areas with plumbing leaks or past water damage
• Basements and lower levels with high humidity
• Attics with improper ventilation

Snowmelt, temperature swings and ground moisture can all contribute to dampness under homes in the Treasure Valley. When moisture is combined with organic material like wood framing or subflooring, mold can grow even in an otherwise “dry” region.

5. Post-COVID, Families Are More Focused on Health and Air Quality

One of the biggest changes we’ve seen is how seriously families now take indoor air quality. After the COVID-19 pandemic, people are more aware of what they are breathing and how their environment affects their health.

Mold and poor indoor air quality can be linked to:

• Worsening allergies and asthma
• Chronic cough or throat irritation
• Headaches and fatigue
• Eye and sinus irritation

While not every symptom is caused by mold, it is important to rule out mold growth and moisture issues when health problems seem to flare up at home.

Frequently Asked Questions About Mold and Air Quality

Is mold common in Idaho homes?

Yes. Even though Idaho has a dry climate, we frequently find mold in crawl spaces, basements, attics and areas with past water damage or plumbing leaks. Poor ventilation and trapped moisture are the biggest contributors.

Can I clean mold myself?

Small surface spots can sometimes be cleaned, but if the area is larger than a few square feet, keeps coming back or is connected to a leak or moisture issue, it’s best to call a professional to prevent spreading spores and making the problem worse.

Does homeowners insurance cover mold?

Coverage depends on your policy and the cause of the damage. Some insurance companies have strict limitations on mold coverage. Ness Restoration can help document the damage and provide information you can share with your insurance company.
