What makes our Attic Cleaning & Rodent Proofing in Los Angeles address rodent problems differently? Warm, dry summers push rats and mice to seek cooler nesting spots, and the mature landscaping common in neighborhoods like Los Feliz, Encino, and Silver Lake gives them easy routes to your roofline. Once inside, rodents shred insulation, soak it with urine, and chew through wiring. A family of roof rats can destroy an attic in a single season, and most of the damage sits above the living space where you never see it. The fix is methodical: remove what’s contaminated, sanitize what’s left, and seal the structure so they can’t return.
We’re not a pest control company that also does insulation, and we’re not a generalist contractor who treats this as a side job. Attic restoration is one of our ten core services, backed by our 90-Day Done Right Promise. If the work isn’t right, we make it right. Written, not implied. Neil Ashford founded Warmline Insulation Co. on a simple read of the Los Angeles market: homeowners need one contractor who understands the connection between pest damage, air quality, and thermal performance. We’ve spent 15 years becoming exactly that.
What Our Attic Cleaning & Rodent Proofing Service Includes
Attic Cleanout
Attic cleanout means removing everything that shouldn’t be in your attic: old insulation, rodent nests, droppings, food caches, torn duct wrap, dead rodents, and decades of dust and debris. In Los Angeles homes built before 1990, we regularly find multiple layers of material that should have been removed years ago. Our crew vacuums the attic to the decking using commercial HEPA-filtered equipment, not a shop vac. Every bag of contaminated material leaves the property in sealed, labeled containers. The result is a clean substrate that allows us to see the attic structure clearly and plan the rest of the work.

Attic Sanitizing & Decontamination
Once the attic is empty, we sanitize. Rodent urine and feces carry hantavirus, leptospirosis, and salmonella, and dried droppings aerosolize into airborne particles that drift through ceiling gaps into your living space. We apply an EPA-registered antimicrobial treatment to every surface: decking, trusses, rafters, and the interior side of the roof sheathing. In homes near the coast in Manhattan Beach or El Segundo, we also check for mold growth and treat it at this stage. After sanitizing, we install fresh insulation, so you’re not blowing new material over contaminated wood.

Rodent Proofing & Exclusion
Rodent proofing is the difference between a one-time cleanup and a recurring problem. We seal every opening larger than a quarter inch along the roofline, eave vents, gable vents, pipe penetrations, and the attic hatch. Materials vary by the gap: galvanized steel mesh, metal flashing, pest-block expanding foam, and weatherproof sealants. A professional has to understand rodent behavior to find entry points that a quick visual inspection misses, especially along intersections of roof planes where gaps often hide. Los Angeles roof rats can compress their bodies through openings smaller than a dime, and squirrels will gnaw through plastic vents, so every seal has to be robust.

Attic Restoration
Attic restoration is the full reassembly after cleaning and exclusion: new insulation installed to the proper R-value for Los Angeles’ climate zone, air sealing around light fixtures and partition walls, and replacement baffles at the eaves. Blown-in fiberglass from Owens Corning or GreenFiber is a frequent choice for open attics, giving consistent coverage and good thermal performance. We might recommend a radiant barrier for homes in the Valley where summer attic temperatures hit 140°F. The finished attic is clean, sealed, properly insulated, and frustratingly difficult for any future rodent to breach.

Brands We Service for Attic Cleaning & Rodent Proofing
We install and work around all major insulation brands, and our crews are trained on the specific characteristics of Owens Corning, GreenFiber, and Johns Manville products. When you choose Owens Corning blown-in fiberglass, the pink material you see in our trucks meets the strict specification Owens Corning sets for its certified installers. We’ve handled thousands of attics with these materials, and our team knows how to restore them without damaging the roof structure.
GreenFiber is a sanctuaries-certified cellulose made from recycled paper, and it’s a smart choice for Los Angeles homeowners who want maximum coverage in tight attic spaces where a hose-fed product reaches odd corners fiberglass sometimes misses. We’ve completed hundreds of GreenFiber installs in older hillside homes where the attics have irregular joist spacing. Whether you have Owens Corning, GreenFiber, Johns Manville, or any other make, we can clean, sanitize, and re-insulate the space.
Signs You Need Attic Cleaning & Rodent Proofing Right Now
- You hear scratching or running sounds in the ceiling at dusk. Roof rats and mice are crepuscular, meaning they’re most active just after sunset and just before sunrise. If you hear scampering above your bedroom between 6 and 10 PM, you have an active infestation. Rodents never leave on their own; they expand.
- Your energy bills climbed without a change in usage. Rodents mat down and shred insulation, destroying its R-value. A 2,000-square-foot home in Los Angeles that loses attic insulation can see cooling costs rise $40 to $80 per month in summer. The rodents are literally throwing away the money you spent on insulation.
- You smell a musty, ammonia-like odor in the upstairs hallway. That’s rodent urine. A single rat produces 40 to 50 droppings per day and urinates continuously as it travels. Once the odor reaches the living space, the contamination level in the attic is severe. It’s not a cleaning problem; it’s a health hazard.
- You found droppings in the attic, garage, or pantry. Fresh droppings are dark and moist; old droppings are gray and crumble easily. If you see droppings anywhere, the attic is the source. Rodents follow food trails down interior wall cavities, and every path they use is another gap we need to seal.
- You’ve had pest control out before, and the rodents came back. Trapping removes animals, not access. If entry points stay open, new rodents move in within weeks. A proper exclusion job has to accompany any trapping effort, and that’s exactly what our rodent proofing does.
Our Attic Cleaning & Rodent Proofing Process - Step by Step
Here’s exactly what happens when you call us. The process is transparent, and most jobs are completed in a single visit, so you won’t be juggling multiple contractors or waiting weeks between phases.
- 1
Inspection and quote. We walk the attic with you if you want, or we send you photos while we work. We check insulation depth, rodent activity, entry points, and ventilation. Then we give you an upfront, line-item price before any work begins. No hourly billing, no surprise fees.
- 2
Removal of contaminated insulation and debris. Using commercial HEPA vacuums and sealed bags, we remove all existing insulation, nests, droppings, and debris. The attic is worked clean to the decking. This is the stage where we also remove any dead rodents and catalog the extent of wire damage.
- 3
Sanitizing and decontamination. Every surface gets an EPA-registered antimicrobial treatment. We pay special attention to areas where rodent urine has soaked into wood, because that’s where the smell and bacteria linger. Attics in humid zones near Marina del Rey sometimes need a second pass.
- 4
Rodent proofing and exclusion. We seal every entry point from the inside and outside. That includes eave gaps, construction joints, pipe chases, vent screens, and any tunneled entry along the roof deck. We use steel mesh for large gaps and professional-grade sealants for small ones. Rodents don’t chew through steel.
- 5
Re-insulation and final inspection. We install fresh insulation to the correct depth for your home’s need, then run a thermal check to confirm coverage is uniform. We walk the attic with you or send a photo report. If anything looks wrong in the next 90 days, we come back and fix it under the 90-Day Done Right Promise.
How Much Does Attic Cleaning & Rodent Proofing Cost in Los Angeles?
A typical attic cleanout with sanitizing in Los Angeles runs $450 to $950 for homes up to 1,500 square feet. For a full breakdown, see our Attic Cleaning & Rodent Proofing pricing page. Rodent proofing and exclusion adds $250 to $700 depending on how many entry points we need to seal. Full attic restoration, meaning cleanout, sanitizing, exclusion, and new insulation, starts around $1,200 and can reach $1,800 or more for larger homes with heavy contamination or multiple roof intersections. Every job is priced differently because every attic is different.
What affects the price? The size of the attic, the depth and type of existing insulation, the number of entry points, accessibility, and whether we’re also replacing damaged ductwork or vent screens. A one-story ranch in Hawthorne is simpler than a three-story craftsman in View Park-Windsor Hills with a steep roof and tight eaves. You avoid overpaying by working with a company that gives you a written, line-item quote before work starts, not after. Our estimates are free, and we have three standing offers that apply: $50 off any repair over $250, an $89 seasonal tune-up, and a permanent 5% discount for seniors and veterans. Call (213) 782-8141 for an exact quote, and remember that a live person answers every call, day or night.
