Attic Insulation, Rodent Proofing & Attic Cleaning in San Ysidro, CA

San Ysidro’s mix of older single-family homes, townhomes, and multi-unit buildings sits in one of the warmest and busiest border areas in South San Diego. High traffic, nearby commercial zones, and aging construction mean many attics are hot, dusty, and affected by rodent activity. A lot of properties still have original insulation and leaky ductwork that can’t keep up with today’s comfort and energy standards. Attic Shield restores San Ysidro attics with a full system approach — including 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 San Ysidro Homes

Between older roof structures, proximity to commercial corridors, and hot inland-leaning weather, San Ysidro attics face a unique set of issues. In single-family homes, duplexes, and apartments we often find:

• Original or builder-grade insulation that is thin, dirty, or badly settled
• Rodent activity entering from alleys, yards, utility lines, and shared walls
• Unsealed wall tops, wiring holes, and plumbing penetrations leaking conditioned air
• Duct systems that are leaking, kinked, or poorly insulated above living spaces
• Hot attic temperatures radiating heat into bedrooms and living rooms

These problems show up as hot, stuffy rooms, musty or rodent odors, A/C systems that run constantly, and SDG&E bills that feel too high for the size of the home. Attic Shield fixes the attic as a system — not just by throwing new insulation on top of existing problems.

Attic Shield Services for San Ysidro Homeowners

Attic Cleaning & Light Debris Removal

For San Ysidro homes where insulation can be saved but the attic is dusty, cluttered, or lightly contaminated, Attic Shield performs professional attic cleaning. We remove loose debris, old materials, and accessible droppings so the space above your ceilings is cleaner and ready for rodent proofing, air sealing, or future insulation upgrades.

Insulation Removal (Old, Damaged, or Contaminated Insulation)

Many San Ysidro attics still have original or heavily degraded insulation — thin batts, patchy blown-in, or material contaminated by rodents and roof leaks. We remove old insulation using contained, high-powered equipment so dust and fibers stay out of your living space, creating a clean base for sanitization, air sealing, and new insulation installation.

Rodent Proofing for San Ysidro Rooflines & Shared Structures

Dense neighborhoods, alleys, and nearby commercial zones make rodent access a major issue in San Ysidro. Rodents use fences, utility lines, and tight gaps to reach rooflines, then nest in insulation and chew building materials. We inspect vents, eaves, roof intersections, stucco gaps, and penetrations, then seal accessible entry points using rodent-resistant materials for long-term exclusion — not just a quick trapping visit.

Rodent Waste Removal & Sanitization

Rodent droppings, urine, and nesting materials create odors and health concerns — especially when they sit directly above bedrooms and living spaces. Attic Shield removes heavily contaminated material and applies sanitizing products to exposed framing and surfaces to help reduce odor and bacteria in the space above your home.

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

When San Ysidro attics have long-term or severe rodent infestations, full attic sanitization is often the safest, most effective step. This deeper treatment targets framing, sheathing, and other surfaces to help neutralize contamination before new insulation is installed and the attic is sealed properly.

Attic Air Sealing (Stop Drafts & Energy Loss)

Older San Ysidro homes and multi-unit buildings often have big air gaps at wall tops, chases, and penetrations. Those openings allow conditioned air to escape into the attic while pulling hot attic air and outdoor pollutants back into the house. We seal these bypasses so your home holds temperature better, rooms feel more consistent, and your HVAC doesn’t have to run nonstop in the heat.

New Attic Insulation Installation (R-38+ for San Ysidro’s Climate)

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

Duct Repair & Replacement in San Ysidro Attics

Long attic runs, older remodels, and tight mechanical spaces can leave San Ysidro homes with kinked, leaking, or undersized ducts. We repair or replace accessible ductwork, seal all joints, and ensure ducts are properly insulated so more of your cooled or heated air makes it into your rooms — not wasted in a hot attic.

Our San Ysidro Attic Restoration Process

Every San Ysidro project begins with a detailed attic inspection and full photo report. We show you insulation levels, rodent evidence, air leaks, and duct issues, then design a scope of work around your home and budget. A complete attic restoration usually follows this sequence:

1. Protect floors, hallways, 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 San Ysidro’s climate.
7. Repair or replace accessible ductwork if included in your scope.
8. Provide after-photos so you can see the final, restored attic condition.
