Attic Insulation, Rodent Proofing & Attic Cleaning in Bostonia, CA

Bostonia sits right between El Cajon and Lakeside, with many homes built decades ago and upgraded over time. Behind the drywall, a lot of attics still have old insulation, rodent tunnels, leaky ducts, and unsealed penetrations that make rooms hot, drafty, and harder to keep comfortable. Attic Shield helps Bostonia homeowners restore their attics with attic cleaning, insulation removal, rodent proofing, rodent waste removal, attic sanitization, attic air sealing, insulation installation, and duct repair & replacement.

Attic Problems We See in Bostonia Homes

Bostonia has a mix of older single-story homes, additions, and small multifamily properties. The hot East County climate and older construction details create a lot of recurring attic issues, including:

• Old or original insulation that’s thin, dirty, or compressed from age
• Rodent nests, droppings, and tunnel paths through insulation
• Unsealed wall tops, can lights, and chases leaking cool air into the attic
• Leaky or crushed ductwork that kills airflow to certain rooms
• Very hot attic temperatures that push heat back down into bedrooms and hallways

All of this leads to hot rooms, dusty odors, noisy A/C cycles, and high SDG&E bills. Attic Shield doesn’t just throw more insulation on top — we fix the whole attic system.

Attic Shield Services for Bostonia Homeowners

Attic Cleaning & Light Debris Removal

If your attic is mostly intact but full of dust, debris, and light rodent evidence, Attic Shield can perform a professional attic cleaning. We remove loose debris, accessible droppings, and surface dust so the space above your ceilings is cleaner and ready for rodent proofing, air sealing, and future insulation upgrades if needed.

Insulation Removal (Old, Damaged, or Contaminated Material)

Many Bostonia homes still have insulation from the 70s, 80s, or 90s. It’s often flattened, dirty, or contaminated by years of rodent activity. We remove old insulation using controlled, contained methods so dust and fibers don’t spread into your home, giving us a clean base for sanitization and new insulation installation.

Rodent Proofing for Bostonia Rooflines & Eaves

In older East County neighborhoods, rodents use fences, trees, and utility lines to reach rooflines. Once in the attic, they tunnel through insulation and nest near ducts and wires. We inspect eaves, vents, roof intersections, and penetrations, then seal accessible entry points using rodent-resistant materials for long-term exclusion, not just a quick trap-and-hope fix.

Rodent Waste Removal & Sanitization

Rodent droppings, urine, and nesting materials produce strong odors and an unhealthy attic environment. Attic Shield removes heavily contaminated material and applies sanitizing products to exposed surfaces to help reduce odor and bacteria in the attic space above your home.

Full Attic Sanitization (For Severe or Long-Term Activity)

When Bostonia attics have heavy or long-running rodent activity, we recommend full attic sanitization. This deeper treatment targets framing, sheathing, and other surfaces to help neutralize contamination before we rebuild the attic with sealing and new insulation.

Attic Air Sealing (Stop Energy Loss & Drafts)

Gaps at the top of walls, around can lights, and at plumbing or wiring penetrations allow conditioned air to escape into the attic while pulling super-hot attic air back into your home. We seal these bypasses so your Bostonia home holds temperature better and your HVAC system doesn’t have to run as long or as hard in summer heat.

New Attic Insulation Installation (R-38+ for Bostonia)

After cleaning, sanitization, rodent proofing, and air sealing, we install new insulation that meets or exceeds California Title 24 requirements. In Bostonia, we typically bring attics up to R-38 or higher to help bedrooms, hallways, and living areas stay more comfortable during East County heat waves.

Duct Repair & Replacement in Bostonia Attics

Older homes and remodels often have duct systems that were patched together over time. We repair or replace accessible duct runs, seal joints, and ensure ducts are properly insulated so more of your cooled or heated air reaches the rooms where you actually need it instead of being lost in the attic.

Our Bostonia Attic Restoration Process

Every project in Bostonia starts with a detailed attic inspection and photo documentation. We show you exactly what we see — insulation levels, rodent activity, air leaks, and duct issues — and then build a scope of work around your home and budget. A full attic restoration usually follows this sequence:

1. Protect floors, stairs, and attic access with coverings.
2. Remove old, damaged, or contaminated insulation where necessary.
3. Perform rodent waste removal and apply sanitization products.
4. Seal rodent entry points along rooflines, eaves, vents, and penetrations.
5. Air seal major gaps between your living space and the attic.
6. Install new attic insulation to the proper R-value for the East County climate.
7. Repair or replace accessible ductwork if included in your scope.
8. Provide after-photos so you can see the finished condition of your attic.
