What Our Attic Cleaning & Rodent Proofing Service Includes
Most Fullerton attics we open have a mix of problems: old insulation packed with droppings, gnawed wiring, torn ducting, and entry points the rodents have been using for months. We treat the whole space as one job, not a series of upsells. Here’s exactly what we do when we clean and rodent-proof an attic in Fullerton.
Attic Cleanout
We remove everything that shouldn’t be there: contaminated insulation, old rodent nests, droppings, food caches, dead rodents, and whatever else has accumulated over the years. In Fullerton homes built in the 1950s through the 1980s – especially around the Maple and Raymond Hills neighborhoods – we regularly pull out rock wool and fiberglass batts that have been shredded into nesting material. Once the space is empty, we can actually see what’s happening: where the entries are, what damage has been done, and whether your ductwork or framing needs attention. The cleanout is the foundation of everything else.
Attic Sanitizing & Decontamination
After the debris is gone, we sanitize the entire attic. We use an EPA-registered disinfectant applied through a fogging system that reaches corners and cavities where rodents have been nesting. This neutralizes urine, feces, and the pheromone trails that attract new rodents into the same space. It also helps with the smell that creeps into your living areas during Fullerton’s warmer months when attic temperatures climb past 120 degrees. You can’t just vacuum droppings and call it done; the pathogens and the scent markers have to be neutralized or the problem comes back.
Rodent Proofing & Exclusion
This is the part that actually ends the problem. We identify every entry point a rodent is using – roof gaps, vent openings, pipe penetrations, soffit gaps, and especially the gaps where gable vents and eaves meet. Fullerton squirrels and roof rats are persistent; if there’s a hole the size of a quarter, they’ll use it. We seal entries with steel mesh, galvanized metal flashing, and exclusion-grade sealants that rodents can’t chew through. Caulk and spray foam alone won’t stop them; they’ll gnaw right through. We build the fixes to last, and we don’t call the job done until we’ve checked every linear foot of the attic perimeter.
Attic Restoration
Once the space is clean and sealed, we bring it back to a healthy, functional condition. That usually means blowing in fresh insulation – we work with Owens Corning and GreenFiber products because they hold up well in Fullerton’s dry heat and we know exactly how they perform over time. We also repair or replace damaged ducting, check that vents are open and functioning, and make sure the attic is properly ventilated. The goal is an attic you don’t have to think about again. That’s the standard we’ve held for over 25 years, and it’s what the Done Right Promise covers.

Signs You Need Attic Cleaning & Rodent Proofing Right Now
- Scratching or scurrying sounds in the ceiling, especially at night. Roof rats and mice are nocturnal. If you hear movement in your attic after sunset around Fullerton, something is living up there right now. Rodents don’t leave on their own; they’ve found food, warmth, and safety. The longer they stay, the more damage they do.
- Droppings in the attic or around your garage. Rat droppings look like dark grains of rice; mouse droppings are smaller and pointed at both ends. Finding them means there’s active rodent traffic. It also means the insulation above your ceiling is slowly being contaminated, which affects your indoor air quality every time your HVAC system pulls air through the attic.
- A strong ammonia or musty smell in the hallways or bedrooms. Rodent urine has a distinct, sharp smell that seeps through ceiling drywall over time. In Fullerton’s summer heat, that odor gets stronger as the attic bakes. If you notice it in one room but not another, the nesting site is usually directly above that room.
- Chewed wiring or gnaw marks on wood and ducting. Rodents chew constantly to keep their teeth from overgrowing. In attics across Fullerton, we’ve found Romex sheathing stripped, AC line sets damaged, and ducts chewed open. This is a fire hazard and an efficiency killer. If you spot gnaw marks during a visual check, don’t wait.
- Insulation that looks matted, compressed, or disturbed. Healthy blown-in insulation sits evenly and fluffy. When rodents are active, you’ll see trails, tunnels, and flattened nesting areas. That damage reduces your insulation’s R-value, which means higher cooling bills in Fullerton’s long warm season and an attic that’s working against you.
Our Attic Cleaning & Rodent Proofing Process - Step by Step
- 1
Free attic inspection and honest assessment. We start by getting into your attic and looking at everything: insulation condition, rodent evidence, entry points, ventilation, and wiring. We take photos so you can see exactly what we’re seeing. Then we give you a straight recommendation with a firm price. If you’ve already got a written estimate from another company, we’ll give you a free second opinion. No trip charge inside the service county.
- 2
Full containment and safety setup. Before we start pulling contaminated insulation, we set up a HEPA-filtered containment system so dust, droppings, and insulation fibers don’t spread through your home. Our technicians are uniformed, background-checked, and trained in safe removal practices. We protect your floors with drop cloths, and we keep the whole job contained.
- 3
Insulation removal and debris extraction. We use commercial-grade extraction equipment to remove the old insulation, nesting material, and debris. Every bit of contaminant gets bagged and removed from the property properly. In most Fullerton homes, this takes two to four hours. This is the point where we can fully assess what’s underneath: the framing, wiring, and any hidden structural issues.
- 4
Sanitizing, sealing, and exclusion. With the attic empty, we fog the entire space with an EPA-registered disinfectant to kill pathogens and neutralize odor. Then we close every entry point we’ve identified with steel mesh, metal flashing, and rodent-proof sealants. We check the roof line, the soffits, the gable vents, and every penetration. If a rodent has a way back in, this is where we eliminate it.
- 5
Fresh insulation and final verification. We blow in new insulation – typically Owens Corning AttiCat or GreenFiber cellulose, depending on your home’s needs and budget – and restore the attic to full efficiency. Then we do a final walkthrough with you, show you the before-and-after photos, and confirm the work is complete. Every job carries the Done Right Promise for life. If something’s not right, we come back and make it right. No fine print, no runaround.
How Much Does Attic Cleaning & Rodent Proofing Cost in Fullerton?
A typical attic insulation removal and cleaning for a 1,200-square-foot Fullerton ranch costs between $450 and $900, while our Attic Cleaning & Rodent Proofing - Fullerton service with full exclusion on the same home typically adds $400 to $600 depending on how many entry points need sealing. For larger two-story homes in neighborhoods like Coyote Hills or around Laguna Lake, a complete cleanout, sanitizing, and full exclusion package usually lands between $1,000 and $1,400. If you need fresh insulation blown in afterward, that’s priced separately based on square footage and the R-value we’re targeting for Orange County’s climate zone.
Several factors move the price up or down. The size of the attic and the depth of the existing insulation are the big ones, because removal time drives labor. Severe infestations with extensive contamination, damaged ductwork, or chewed wiring add time and materials. The number of entry points matters too; older Fullerton homes with original wood soffits and gable vents tend to have more gaps than newer construction. The best way to avoid overpaying is to get a clear, line-item estimate from someone who has actually been in your attic, not a phone quote. Our estimates are free, and we’ll walk you through exactly what you’re paying for before any work starts. Call (657) 216-9948 and we’ll schedule the inspection.
