Attic Insulation, Rodent Proofing & Duct Work in San Diego, CA

AtticShield is a licensed and insured attic & crawl space contractor serving homeowners throughout San Diego. We handle everything from attic cleaning and insulation removal to rodent proofing, rodent waste removal, attic sanitization, air sealing, new insulation installation, and duct repair & replacement.

Serving Every Corner of San Diego

From coastal neighborhoods like Pacific Beach, Ocean Beach, and La Jolla to inland areas such as Mira Mesa, Rancho Bernardo, Clairemont, and greater San Diego, your attic takes the full hit of heat, humidity, and rodent pressure. Attic temperatures can climb past 130°F in summer, baking old insulation and pulling hot, dusty air into your home.

Our technicians follow a step-by-step process — inspection, documentation, removal, sanitization, rodent proofing, air sealing, insulation, and duct repair — so you’re not just “covering up” problems with more insulation. You’re actually fixing the source of the issue.

Attic Cleaning & Light Decontamination

For attics with light rodent activity, dust, and surface debris, we provide professional attic cleaning to remove loose droppings, dirt, and contaminants from accessible areas. This is often the first step before deeper rodent work or insulation upgrades.

Attic Insulation Removal (Old or Contaminated)

Many San Diego homes still have original insulation that’s thin, dirty, or contaminated with rodent urine and droppings. We remove it using controlled methods and sealed bags to prepare the space for proper sanitization, rodent proofing, and new insulation.

Rodent Proofing for Attics & Rooflines

Roof rats love San Diego. We inspect your roofline, eaves, vents, pipes, and construction gaps, then seal entry points with rodent-resistant materials. The goal is to stop new rodents from getting back in after cleanup.

Rodent Waste Removal & Sanitization

When there’s heavy activity, droppings and urine don’t just smell — they affect air quality. We remove nests and contaminated material and apply EPA-approved disinfectants to help neutralize bacteria, odors, and allergens from rodent contamination.

Full Attic Sanitization & Decontamination

For severe contamination, we perform deeper attic sanitization, treating exposed framing and sheathing. This step is critical before reinstalling insulation so you’re not trapping odors and bacteria under new material.

Attic Air Sealing (Energy Efficiency Upgrade)

We seal gaps, top plates, chases, around lights, and other penetrations to reduce air leakage between your living space and attic. This helps keep conditioned air where it belongs and reduces hot/cold spots throughout the home.

New Attic Insulation Installation (R-38+)

Once the attic is cleaned, sealed, and rodent proofed, we install new insulation to meet or exceed California Title 24 recommendations — typically R-38 or higher in the San Diego area. We use quality materials designed for long-term performance.

Duct Repair & Replacement

Leaky or crushed ducts waste energy by dumping cooled or heated air into the attic instead of your rooms. We repair or replace damaged duct runs, seal joints, and ensure ducts are properly insulated so your HVAC system can do its job.

FAQ – Attic & Duct Work in San Diego

Do you offer free inspections in San Diego?

Yes. We offer free inspections with photos and a detailed quote so you can see exactly what’s happening in your attic before you decide on any work.

How long does a full attic project usually take?

Most homes take around 1–2 days for insulation removal, sanitization, rodent proofing, air sealing, and new insulation installation. Duct work or very large homes may take a bit longer.

Can you just blow new insulation over my old insulation?

If there’s rodent contamination or very old material, we do not recommend blowing new insulation over the top. The right way is to address removal, sanitation, and rodent proofing first, then install new insulation on a clean base.
