Attic Insulation, Rodent Proofing & Attic Cleaning in National City, CA

National City has some of the oldest residential construction in South Bay and some of the warmest attic temperatures due to low-slope roofs, aging insulation, and older ventilation systems. Many homes still have original insulation, active rodent activity, leaking ducts, and unsealed attic gaps that drive energy bills up and reduce comfort. Attic Shield provides complete attic restoration for National City homeowners, including attic cleaning, insulation removal, rodent proofing, rodent waste removal, sanitization, air sealing, insulation installation, and duct repair & replacement.

Common Attic Problems in National City Homes

National City’s combination of older housing stock, flat roof sections, and warm climate creates unique attic challenges. Common issues include:

• Old or original insulation, often contaminated or severely compressed
• Rodent nests, droppings, and chew damage throughout the attic
• Air leaks around wall tops, wiring holes, and recessed lighting
• Leaking, sagging, or disconnected ductwork
• Extremely hot attic temperatures due to limited ventilation

These issues commonly show up as warm bedrooms, high SDG&E bills, strong odors, excessive dust, and A/C units that run constantly. Attic Shield targets the root of each issue to rebuild the attic system from the ground up.

Attic Cleaning

Great for homes with dust, light debris, or minor rodent traces. We clean the attic and prepare it for insulation upgrades or rodent proofing.

Insulation Removal

Many National City homes still have insulation from decades ago. We remove contaminated or ineffective material to create a clean, safe space for new insulation.
