How Spray Foam Prevents Moisture & Mold in Ohio Homes

Moisture is one of the biggest threats to a home’s structural integrity — and to your family’s health. In Ohio's humid summers and snowy winters, unwanted moisture can creep in through gaps and cracks, leading to mold growth and costly damage. Spray foam insulation is one of the most effective tools for keeping that moisture out.

Why moisture control is essential in Avon

Our climate offers plenty of opportunities for condensation: warm, humid outdoor air meets cool indoor surfaces, or vice versa. If moisture gets trapped inside walls, attics, or crawl spaces, it can:

• Feed mold spores.
   
• Rot wood framing.
   
• Reduce the effectiveness of insulation.
   
• Create musty odors and poor indoor air quality.
   

How spray foam insulation works

Spray foam is applied as a liquid that expands into every gap and crack, hardening into an airtight, moisture-resistant barrier.

• Closed-cell spray foam: Offers the highest R-value per inch and is impermeable to water, making it ideal for basements, crawl spaces, and exterior walls.
   
• Open-cell spray foam: While more vapor-permeable, it still provides an excellent air seal and is great for interior applications.
   

Spray foam vs. traditional insulation for moisture control

• Fiberglass and cellulose can absorb moisture, reducing their effectiveness and creating a breeding ground for mold.
   
• Spray foam doesn’t sag, settle, or absorb water, and its continuous seal prevents humid air from infiltrating.
   

Additional benefits of spray foam in Ohio homes

• Energy savings: Reduces heating and cooling costs by up to 50%.
   
• Sound dampening: Creates a quieter indoor environment.
   
• Structural strength: Closed-cell foam can add rigidity to walls and roofs.
   

Where to use spray foam for best results

• Basements and crawl spaces: Stop moisture from seeping through foundation walls.
   
• Attics and rooflines: Prevent condensation from warm air leaks in winter.
   
• Exterior walls: Block wind-driven rain and humid summer air.
