Protected Home Performance

Rodent Proofing and Attic Insulation Installation in Chino Hills, CA

At ELM Insulation and Sound Solutions, we recently completed a rodent-proofing and attic insulation project in Chino Hills. The homeowner was dealing with energy loss, inconsistent temperatures, and concerns about rodents entering the attic through exposed vent openings, which compromised insulation performance and indoor air quality.

Our team removed the old blown-in insulation, installed new attic fiberglass insulation, and sealed vulnerable entry points to restore comfort, efficiency, and protection throughout the home.

ELM Insulation and Sound Solutions did an excellent job on our attic. They removed the old insulation, installed new fiberglass, and sealed the vent that rodents were using.

The Concern

The attic’s existing blown-in insulation had become uneven and ineffective, allowing heat to escape in cooler months and enter during warmer periods, which made it harder to maintain consistent indoor temperatures.

In addition, an unsealed attic vent created an access point for rodents, increasing the risk of contamination, damaged insulation, and compromised air quality throughout the home. These combined issues forced the HVAC system to work harder and reduced overall comfort.

The Solution

Our skilled crew began by carefully removing the old blown-in insulation to eliminate debris, contaminants, and nesting material that had accumulated over time.

After clearing the attic, we addressed the rodent issue by sealing the exposed vent opening, preventing rodents from entering the attic and safeguarding the home from future infestations.

We then installed new fiberglass batt insulation throughout the attic, restoring proper R-values and creating a consistent thermal barrier between the living space and the roof structure.

This integrated approach ensured both insulation performance and long-term protection were fully addressed.

The Result

The new attic insulation and rodent proofing immediately improved comfort and efficiency. The homeowner experienced more stable indoor temperatures, reduced HVAC strain, and improved peace of mind knowing rodents could no longer access the attic.
