Attic Insulation, Rodent Proofing & Attic Cleaning in Rancho Bernardo, CA

Rancho Bernardo homes experience hot summers, cool nights, and long A/C run times — especially in two-story houses and homes with large attics. Many properties still have original insulation, leaky ducts, and rodent activity in attic corners and along rooflines. Attic Shield helps Rancho Bernardo 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.

Why Rancho Bernardo Attics Get So Hot (and Stay That Way)

Rancho Bernardo sits inland, which means stronger heat, more sun exposure, and higher attic temperatures than many coastal neighborhoods. Without proper insulation and sealing, that attic heat bleeds into bedrooms, hallways, and lofts — especially on the second floor. In Rancho Bernardo attics, we commonly see:

• Original or low R-value insulation that’s thin, patchy, or dirty
• Rodent tunneling and nests in corners and around HVAC equipment
• Unsealed top plates, can lights, and chases leaking air into the attic
• Ductwork that is crushed, disconnected, or leaking at joints
• Dust and debris from multiple rounds of electrical or low-voltage work

When all of that stacks together, your home gets hotter, temperatures vary room to room, and your A/C runs longer than it should. Attic Shield focuses on correcting the attic as a system — not just throwing more insulation on top of existing problems.

Attic Shield Services for Rancho Bernardo Homeowners

Attic Cleaning & Light Debris Removal

Some Rancho Bernardo attics don’t need a full tear-out but are dusty, cluttered, and overdue for a cleanup. Attic Shield removes loose debris, accessible droppings, and surface dust, making the attic space cleaner and preparing it for deeper rodent or insulation work if you choose to move forward.

Old Insulation Removal (Thin, Dirty, or Contaminated)

Many homes in Rancho Bernardo still have insulation from original construction or older remodels. This material is often compressed, contaminated, or far below modern R-value. We remove old insulation using controlled, contained methods so dust and fibers don’t spread into your living space, giving you a clean slate for rebuilding the attic correctly.

Rodent Proofing for Rancho Bernardo Rooflines & Eaves

Rodents use fences, trees, and utility lines to access Rancho Bernardo rooflines. Once inside, they nest in insulation and near ductwork. We carefully inspect eaves, vents, roof intersections, and penetrations, then seal accessible entry points using rodent-resistant materials so new rodents can’t simply move in after cleanup is complete.

Rodent Waste Removal & Sanitization

Rodent droppings, urine, and nests don’t just look bad — they can also smell and contribute to 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 space above your ceilings.

Full Attic Sanitization (Severe or Long-Term Infestations)

When Rancho Bernardo attics have heavy, long-term rodent activity, we recommend full attic sanitization. This deeper process treats framing, sheathing, and other surfaces to help neutralize contamination before we install new insulation and complete the rebuild.

Attic Air Sealing (Stop Conditioned Air from Escaping)

Air leaks at the top of your home allow expensive conditioned air to escape into the attic and pull hot attic air back into your living space. We seal major bypasses — top plates, can lights, chases, and penetrations — so your home holds temperature better and your HVAC system doesn’t have to fight as hard against Rancho Bernardo heat.

New Attic Insulation Installation (R-38+ for Inland Climate)

After cleaning, sanitization, rodent proofing, and air sealing, we install new insulation that meets or exceeds California Title 24 requirements. In Rancho Bernardo, we typically aim for R-38 or higher to help keep second floors, bonus rooms, and lofts more comfortable through hot inland days and cooler nights.

Duct Repair & Replacement in Rancho Bernardo Attics

Duct systems in older or heavily remodeled homes are often kinked, crushed, or leaking at joints. We repair or replace accessible duct runs, seal connections, and ensure ducts are properly insulated so more of your cooled or heated air actually reaches your rooms instead of getting lost in the attic.

Our Rancho Bernardo Attic Restoration Process

Every project in Rancho Bernardo starts with a detailed attic inspection and photos. We walk you through what we see — insulation levels, rodent evidence, air leaks, and duct conditions — and then build a scope of work that fits your home and your budget. A full 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 the roofline, eaves, vents, and penetrations.
5. Air seal major gaps between the living space and 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.
