Trusted Attic Cleaning & Rodent Proofing for Pomona Homeowners
Pomona Attic Cleaning & Rodent Proofing typically costs between $450 and $1,800 depending on attic size, contamination level, and whether full exclusion work is needed. Most jobs are completed in a single visit. If you’re hearing scratching sounds after sunset or noticing droppings near your attic access hatch, you’re dealing with a problem that won’t resolve itself, and the damage compounds every week you wait.
Warmline Insulation Co. has been cleaning and sealing attics across Pomona since 2011. Our technicians are background-checked, uniformed, and trained to handle everything from light debris removal to full decontamination and rodent exclusion. We’re led by Neil Ashford, who built this company on a simple promise: if it’s not done right, we make it right, in writing, for 90 days. Call (626) 341-0830 and a live person answers, 24/7. No voicemail, no answering service, no runaround.
What Our Attic Cleaning & Rodent Proofing Service Includes
This isn’t a one-size-fits-all service. We scope every Pomona attic based on what’s actually up there: the age of the insulation, the extent of animal activity, the condition of your ductwork and framing. Then we build a plan that covers exactly what your attic needs. Here’s what falls under this service, one piece at a time.
Attic Cleanout
An attic cleanout means removing everything that shouldn’t be in your attic: old insulation, rodent nesting material, debris from construction or previous remodels, dead pests, and years of accumulated dust. In Pomona’s older neighborhoods, like Lincoln Park and Wilton Heights, we regularly pull out insulation that’s been in place since the 1960s or 70s and has been compromised by rodent traffic. We haul it all away, leaving a clean deck ready for whatever comes next, whether that’s new insulation, air sealing, or both. Our team brings commercial-grade vacuums and disposal equipment into your home carefully, protecting floors and walls along the path to the attic.
Attic Sanitizing & Decontamination
Rodent droppings and urine aren’t just unpleasant, they’re a health hazard. Attic sanitizing removes the biohazardous material left behind after an infestation, treating the affected surfaces with antimicrobial and enzyme-based cleaning agents that break down waste, neutralize odors, and reduce the risk of airborne pathogens circulating through your home. In Pomona’s hot summers, attic temperatures can exceed 130°F, which bakes those contaminants and pulls them into your living space through ceiling penetrations. We fog, spray, and wipe down surfaces after the cleanout, so the attic isn’t just empty, it’s actually clean.
Rodent Proofing & Exclusion
Cleaning an attic without sealing the entry points is a temporary fix, because the rodents that found their way in will find their way back. Rodent proofing means identifying every possible access point, from roof vents and eave gaps to plumbing stacks and utility penetrations, then sealing them with materials rodents cannot chew through: steel mesh, metal flashing, and sealants rated for pest exclusion. We’ve seen Pomona attics where rats were entering through gaps as small as a quarter inch. Our exclusion work closes those gaps and includes a post-seal inspection to verify nothing is still active inside before we call the job done.
Attic Restoration
After cleanout and exclusion, many Pomona attics need restoration work to get back to a healthy state. That means replacing damaged insulation, repairing chewed wiring or ductwork, addressing moisture issues from roof leaks or condensation, and installing new insulation where the old material was removed. Warmline Insulation Co. handles restoration in-house, so you’re not coordinating multiple contractors. We install products from CertainTeed, Icynene, and GreenFiber, matched to your attic’s ventilation profile and Pomona’s climate needs. One crew, one visit, a fully restored attic.

Brands We Service for Attic Cleaning & Rodent Proofing
We work with insulation and building material brands that have proven themselves in Southern California attics, and we service all of them. If your attic has CertainTeed insulation that’s been compromised by rodent activity, we know how to assess what’s salvageable and what needs replacement, and we stock their paired products so the new material integrates cleanly with what remains. We’ve restored hundreds of Pomona attics with CertainTeed batt and blown-in products, and we’re familiar with their density and coverage specifications so your R-value stays consistent.
For homeowners with spray foam insulation from Icynene or Demilec, the cleaning and exclusion process requires a different approach. Foam doesn’t get replaced as easily as batt insulation, so our technicians are trained to remove contaminated sections surgically and re-foam only where needed, saving you money versus a full tear-out. GreenFiber blown-in cellulose is common in Pomona homes from the 1990s and 2000s, and our teams know how to vacuum out the contaminated top layer, sanitize the space, and blow in fresh material on the same visit. Whether you have these brands or any other, we can service your attic correctly.
Signs You Need Attic Cleaning & Rodent Proofing Right Now
Attic problems rarely announce themselves politely. Here’s what Pomona homeowners notice before they call us, and what each sign actually means.
- Scratching, scurrying, or thumping sounds in the ceiling at dusk and dawn. Rats and mice are most active in the hours around sunset and sunrise. If you hear movement in the ceiling right as it gets dark, you have an active infestation, not a “maybe.” Those sounds mean rodents are nesting, breeding, and damage is accumulating.
- Droppings near the attic access hatch, in the garage, or along fence lines. Rodents leave a trail. Finding droppings in your garage or near your attic ladder means they’re using your home as a highway. Those droppings can carry hantavirus and salmonella, and they break down into airborne dust that circulates through your HVAC system.
- A sharp, musty odor upstairs that gets worse when the AC kicks on. Rodent urine and nesting materials have a distinct smell that lingers. When your air handler pulls air through ceiling penetrations, it draws attic odors into your living space. If the smell is concentrated around vents or the attic hatch, the source is above you.
- Damaged or chewed wiring, ductwork, or roof decking visible in the attic. Rats and mice chew constantly to keep their teeth from overgrowing. They gnaw wires, which creates a fire risk, and they tear through flexible ducts, which wastes conditioned air and drives up your energy bills. If you see chew marks, the problem is active and structural.
- Insulation that looks matted, uneven, or compressed in patches. Rodents create trails and nests inside insulation. Matted down areas are their highways. Fluffy, consistent insulation should have uniform loft, not trails carved through it. Matted insulation loses its R-value, which is why rodent damage and higher cooling bills in Pomona summers often go together.
If any of these signs ring true, don’t wait. Rodent populations double fast, and the longer an infestation runs, the more expensive the cleanup gets. Call (626) 341-0830 and we can have a technician at your Pomona home quickly.
Our Attic Cleaning & Rodent Proofing Process - Step by Step
We don’t show up and wing it. Every Pomona attic job follows a process built over 15 years of work, and we’re transparent about each step so you know what to expect.
- 1
Inspection and assessment. We start with a full attic inspection: entry points, contamination zones, insulation type and depth, ventilation, and any signs of active infestation. We photograph everything so you can see what we see. Neil Ashford built this company on honest diagnosis, and that starts with showing you the problem before we quote the fix.
- 2
Containment prep. Before we disturb anything, we contain the work zone. That means sealing off the attic access, protecting your floors and walls, and setting up negative air pressure where needed so contaminated dust doesn’t migrate into your living space. We treat your home like our own, because we’re guests in it.
- 3
Cleanout and removal. We remove all contaminated insulation, nesting material, droppings, and debris. Our commercial vacuums handle fine particulate, and we bag everything for proper disposal. In most Pomona attics, this takes a few hours. For heavily infested spaces, we may schedule two visits to ensure thoroughness without rushing.
- 4
Sanitizing and decontamination. After the physical removal, we apply enzyme-based cleaners and antimicrobial treatments to all affected surfaces. This step kills odor-causing bacteria, breaks down remaining organic residue, and makes the attic safe to enter. We also check for moisture and treat any areas where condensation or minor leaks have promoted mold growth.
- 5
Exclusion, sealing, and restoration. The final step is making sure the problem stays solved. We seal every entry point with rodent-proof materials, repair or replace damaged insulation, and restore your attic to proper condition. For most Pomona jobs, this all happens in a single visit. We walk through what we did, show you the sealed points, and back the work with our 90-Day Done Right Promise.
How Much Does Attic Cleaning & Rodent Proofing Cost in Pomona?
A typical Attic Cleaning & Rodent Proofing pricing project in Pomona runs between $450 and $1,800. A small attic with light contamination and a few entry points to seal might come in around $450 to $700. A larger attic with heavy rodent activity, multiple entry points, and full insulation replacement runs $1,200 to $1,800 or more. The range is wide because every attic tells a different story.
What affects the price: square footage of the attic, severity of contamination, how many access points need sealing, whether insulation needs partial or full replacement, and accessibility. Attics with steep access, low clearance, or extensive old wiring take longer. Here’s how to avoid overpaying: get a detailed written quote that separates labor from materials, ask what specific exclusion points they found during inspection, and make sure the quote includes sanitizing, not just vacuuming. A cheap quote that skips decontamination leaves you with odors and health risk. Our estimates are free, transparent, and itemized. Most jobs are completed in a single visit, and we offer $50 off any repair over $250, an $89 seasonal tune-up, and a permanent 5% senior and veteran discount.
