Attic Insulation, Rodent Proofing & Attic Cleaning in Otay Mesa, CA

Otay Mesa combines residential neighborhoods, townhomes, and industrial areas with some of the hottest inland temperatures in South Bay. Older insulation, rodent entry points around rooflines, and leaky ducts are common in homes that were never updated for today’s energy standards. Attic Shield helps Otay Mesa homeowners restore and upgrade 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 Otay Mesa Homes

Otay Mesa’s inland heat, sun-exposed roofs, and mix of older and newer construction create predictable attic issues. In single-family homes, townhomes, and duplexes we often find:

• Original or builder-grade insulation that’s thin, dirty, or heavily settled
• Rodent nests, droppings, and trails through insulation and along framing
• Unsealed wall tops, can lights, and chases leaking conditioned air into the attic
• Duct systems that are kinked, leaking, undersized, or poorly insulated
• Very hot attic temperatures pushing heat back into bedrooms and living areas

These issues show up as hot rooms, musty attic odors, A/C systems that never catch up, and spiking SDG&E bills. Attic Shield addresses the causes — not just the symptoms — with a full attic restoration approach.

Attic Shield Services for Otay Mesa Homeowners

Attic Cleaning & Light Debris Removal

For Otay Mesa homes where insulation is mostly intact but dust, debris, or light rodent traces are present, Attic Shield performs 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, or new insulation if needed.

Insulation Removal (Old, Damaged, or Contaminated Material)

Many Otay Mesa homes still have insulation from when they were built — flattened fiberglass batts, patchy blown-in material, or sections contaminated by rodents or roof leaks. We remove old insulation using contained, high-powered systems so dust and fibers don’t spread into your home, creating a clean base for sanitization, air sealing, and new insulation installation.

Rodent Proofing for Otay Mesa Rooflines & Eaves

Open lots, fences, and exterior utilities give rodents easy routes to Otay Mesa rooflines. Once inside, they tunnel through insulation, chew materials, and nest near ducts and wiring. We inspect eaves, vents, roof intersections, stucco gaps, and penetrations, then seal accessible entry points using rodent-resistant materials for long-term exclusion, not just a temporary trapping visit.

Rodent Waste Removal & Sanitization

Rodent droppings, urine, and nesting materials create strong odors and unhealthy attic conditions. 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 living areas.

Full Attic Sanitization (Severe or Long-Term Activity)

When Otay Mesa attics have long-term or severe rodent infestations, we recommend full attic sanitization. This deeper treatment targets framing, sheathing, and other surfaces to help neutralize contamination before we rebuild the attic with air sealing and new insulation.

Attic Air Sealing (Stop Energy Loss & Hot Spots)

Gaps at the top of walls, around recessed lights, and at plumbing or wiring penetrations allow conditioned air to escape into the attic while pulling very hot attic air back into the home. We seal these bypasses so your Otay Mesa home holds temperature better and your HVAC system doesn’t have to work as hard during inland heat waves.

New Attic Insulation Installation (R-38+ for Otay Mesa’s Climate)

After cleaning, sanitization, rodent proofing, and air sealing, we install new insulation that meets or exceeds California Title 24 requirements. In Otay Mesa, we typically bring attics up to R-38 or higher to help bedrooms, living rooms, and upstairs spaces stay more comfortable through hot days and cooler nights.

Duct Repair & Replacement in Otay Mesa Attics

Older duct systems, remodels, and DIY changes can leave Otay Mesa homes with leaking, kinked, or poorly insulated ducts. 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 a super-heated attic.

Our Otay Mesa Attic Restoration Process

Every project in Otay Mesa starts with a detailed attic inspection and full photo documentation. We show you exactly what we see — insulation levels, rodent evidence, air leaks, and duct issues — and then design a scope of work around your home and budget. A complete 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 inland 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.
