Living in Southeast Idaho means dealing with a wide range of weather conditions—from snowy winters and spring runoff to humid summers. These shifts in temperature and moisture create the perfect environment for mold growth if your home isn’t properly protected. Mold can spread quickly, damage property, and affect indoor air quality, so prevention is key.

At Resto Pro Idaho, we help homeowners throughout Pocatello, Chubbuck, Blackfoot, American Falls, and surrounding areas stay ahead of mold issues. Here are the top mold prevention tips every Southeast Idaho homeowner should know.

1. Control Indoor Humidity Levels

Moisture is the leading cause of mold. Keeping indoor humidity low—ideally between 30% and 50%—helps prevent mold colonies from forming.

What you can do:

• Use dehumidifiers in basements and crawl spaces.

• Run exhaust fans in bathrooms, kitchens, and laundry rooms.

• Keep your home well-ventilated, especially during winter when homes are sealed tight.

2. Fix Water Leaks Immediately

Even small leaks can fuel mold growth behind walls, under flooring, and inside cabinets.

Common sources of mold-causing leaks in Southeast Idaho homes:

• Frozen pipe cracks during winter

• Water heater failures

• Dishwasher and fridge line leaks

• Roof damage from snow and wind

• Leaking window frames in older homes

If you notice staining, soft spots, or musty odors, have the area inspected right away.

3. Keep Crawl Spaces and Basements Dry

Many homes in Southeast Idaho have crawl spaces, which naturally trap moisture from the soil.

Prevention tips:

• Install proper vapor barriers

• Ensure vents are open and functioning

• Use a crawl space dehumidifier if moisture levels are high

• Keep stored items off the floor to allow airflow

Moist crawl spaces are one of the biggest mold hotspots in this region.

4. Improve Interior Airflow

Poor ventilation allows moisture to settle on surfaces, creating an ideal environment for mold growth.

Easy airflow improvements:

• Open windows when weather allows

• Keep interior doors open

• Run ceiling fans

• Avoid blocking air vents with furniture or rugs

Better airflow = less trapped moisture.

5. Maintain Your HVAC System

Your HVAC system plays a major role in controlling moisture and air quality.

Ways to prevent mold through HVAC maintenance:

• Replace filters every 1–2 months

• Have your ductwork inspected annually

• Ensure drip pans and drain lines are clean and flowing

• Consider adding a whole-home dehumidifier

A clean system helps keep mold spores from circulating through your home.

6. Act Quickly After Water Damage

Mold can begin growing within 24–48 hours after water exposure. Immediate action is critical.

If you experience:

• Flooding

• Burst pipes

• Water heater leaks

• Storm water intrusion

• Sewage backups

Call a certified water damage and mold remediation team right away. Rapid drying prevents mold from spreading into walls, floors, and insulation.

7. Schedule Professional Mold Inspections

Even if you can’t see mold, it can still be present in hidden areas. Southeast Idaho’s climate and home styles make professional inspections especially valuable.

A trained technician can check:

• Behind walls

• Under carpets

• Inside crawl spaces

• Around HVAC systems

• Under sinks and appliances

Regular inspections help catch problems early before they become costly.
