Attic Insulation Removal & Replacement in Thousand Oaks, CA

Attic insulation removal, sanitation, install R-38 batts

Thousand Oaks, California July 2025 Client: Lisa Janke

Poor thermal performance and air-quality concerns

Our solution

Industrial-grade vacuuming of dust and contaminants
Sanitized the attic to eliminate bacteria and rodent odors
Installed R-38 batt insulation (16″) across the attic floor and walls

Results achieved

Recommended R-38 level reached — reduced heat loss/gain
Even temperatures year-round
Rodent contamination eliminated; healthier air
Added soundproofing benefit from new insulation

Expert note

Attics with rodent activity always require full removal and sanitation. Simply adding new insulation on top of contaminated material risks odor, health hazards, and reduced efficiency.

The difference is amazing. My attic was a mess before, but now it feels fresh and clean. I'm already seeing improvements in how the house holds temperature. The team worked efficiently and left everything spotless.

— Lydia Hom Riotoc

Expert note

Rodent-damaged insulation should never be left in place, even if only small areas are affected — contaminated insulation can spread bacteria and odor throughout a home.

Air Duct & HVAC System Cleaning in Pasadena, CA

9 supply ducts + 1 return, system cleaning for furnace & condenser

Pasadena, California April 2025 Client: Socorro Bayan

Nine supply ducts and one return packed with dust and debris
Uneven cooling and heating inside the home
Furnace and condenser working harder than normal
Old sealant leaks — gaps in duct joints losing air

Our solution

Cleared dust and debris from furnace and condenser
Sealed leaks at joints and connections
Decontaminated ducts to reduce allergens

Results achieved

Cleaner air circulation, less dust in living spaces
Even airflow restored across all rooms

The difference was noticeable right away. The air feels cleaner, and my system doesn't run as long to keep the house comfortable. I'm glad I invested in this service.

— Socorro Bayan

Expert note

Dirty or leaky ducts can waste up to 30% of conditioned air in a home. Even without rodents, dust, allergens, and leaks affect both comfort and health.
