Rodent Prevention and Air Duct Replacement in San Jose, CA by Attic Bros, Inc.

For homeowners dealing with pests and poor indoor air quality, combining rodent prevention and air duct replacement is the most effective way to restore a safe environment. This process involves sealing exterior entry points, removing contaminated insulation, and installing new, clean ductwork. We recently completed a rodent prevention, re-insulation, and air duct replacement project for a local client in San Jose, CA to solve these exact issues. Here is what the client shared about the experience:

“Great and professional service doing rodent prevention reinsulation and duct work. Thorough and confident job done for me. Love these good people doing an excellent job.” – Lori Wong

This feedback reflects our team’s focus on clear results, strong workmanship, and peace of mind.

Homes in the Santa Clara Valley face year-round pest pressure. Our mild climate keeps rodents active, and structural settling in older San Jose neighborhoods creates small gaps where roof rats and mice enter. Once inside the attic, rodents damage insulation and chew through HVAC ductwork. This creates health risks and reduces your system’s efficiency.

Air duct replacement is necessary when rodents tear or contaminate the flexible lines. Clean, sealed ducts improve your airflow and lower energy costs. Because the EPA notes that indoor air pollutants are often significantly higher than outdoor levels, maintaining clean ductwork is essential for your health.

At Attic Bros, Inc., we fix the pest intrusion and the duct damage together for lasting protection.

The homeowner called us after noticing signs of rodent activity in the attic. They heard scratching noises, smelled bad odors, and felt weak airflow from their vents.

During our inspection, we found:

• Rodent droppings and nesting materials
• Contaminated and compressed insulation
• Air ducts with chew holes and debris
• Entry points along the roofline and vents

These issues proved that the home required immediate rodent exclusion and new ductwork.

We built a straightforward plan to restore the attic:

1. Seal exterior rodent entry points
2. Remove all contaminated insulation
3. Clean and sanitize the attic floor
4. Replace torn air ducts with sealed units
5. Install fresh fiberglass insulation
6. Apply permanent rodent-proofing materials

This strategy addressed the active infestation and repaired the structural damage.

We started by removing the ruined insulation. This step eliminates the urine odors and bacteria that attract more rodents. According to the CDC, rodents spread diseases directly through their droppings and urine, making safe removal critical.

Next, we cleaned and sanitized the attic to prepare a safe work surface. We then sealed all exterior entry points. We secured every roof gap and vent with heavy-duty wire mesh to block future pests.

With the attic secure, we replaced the damaged HVAC ducts. We installed new, insulated lines and sealed the connections to ensure strong airflow. Finally, we blew in fresh insulation to restore the home’s thermal barrier.

The project resulted in a clean attic, proper HVAC function, and a rodent-free environment.

Clear communication drives our process. During this project, we:

• Explained the attic inspection findings clearly
• Walked the homeowner through the repair plan
• Provided daily progress updates
• Answered questions about HVAC maintenance

We also shared tips on how to monitor for future rodent activity and maintain a healthy attic.

Fixing duct damage without stopping the rodents guarantees future problems. By tackling rodent prevention and air duct replacement at the same time, we completely resolved the issue. The home now has safe air, consistent heating and cooling, and structural protection against pests.

Look for scratching noises at night, visible droppings, chewed wires, and bad odors. Weak airflow from your vents also indicates torn ducts.

Yes. Rodents contaminate ducts with urine and feces. They also chew holes that waste conditioned air. Replacement ensures your indoor air is clean and your HVAC runs efficiently.

Professional exclusion lasts for years. We use steel mesh and durable sealants that rodents cannot chew through.

Yes. Clean, properly installed insulation traps your conditioned air inside, which lowers your monthly utility bills.

If all gaps are correctly sealed, the risk is minimal. Routine exterior checks help maintain this protection.
