Trusted Attic Cleaning & Rodent Proofing for Glendale Homeowners
Attic Cleaning & Rodent Proofing pricing in Glendale typically runs between $1,200 and $4,500 depending on contamination level and attic size, with most jobs completed in one to two days. At Topside Attic Insulation Glendale, we’ve cleaned, sanitized, and sealed more than 9,000 attics across Los Angeles County since 2016, and we answer calls live at (213) 474-3828 around the clock. If you’re hearing scratching at night, finding droppings in storage boxes, or noticing a persistent ammonia smell from your ceiling, we can usually inspect same-day and start work within 48 hours.
Glendale Attic Cleaning & Rodent Proofing addresses the distinct problems created by our mix of 1920s bungalows in Adams Hill, mid-century ranch homes in Glenoaks Canyon, and newer construction in Verdugo Woodlands. Older homes often have decades of accumulated debris, failed insulation, and multiple rodent entry points where stucco meets wood framing. Newer homes aren’t immune - we’ve found roof rats in attics built in 2019 where builder-grade vent screens failed within two years. The warm, dry climate means rodents breed year-round, and the proximity to the Verdugo Mountains gives roof rats easy highway access to neighborhoods from Montrose to Tropico.
We don’t just clean and trap. Every job starts with a written price before any work starts, includes a documented photo record, and ends with rodent-proofing that addresses how the animals actually got in. Our 365-Day Done Right Promise means if they come back through our work, we return and fix it at no charge. That’s Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool.
What Our Attic Cleaning & Rodent Proofing Service Includes
Attic Cleanout
An attic cleanout is the removal of all contaminated insulation, debris, rodent nesting material, and accumulated storage waste down to the bare ceiling joists. You’ll need this when droppings are visible, insulation is compressed or urine-stained, or when decades of forgotten items have created fire hazards and blocked ventilation channels. At Topside Attic Insulation Glendale, our crews use HEPA-filtered vacuums and sealed containment bags, not shop vacs that recirculate particulates through your home. We document the before condition with photos you’ll receive, and we haul everything to licensed waste facilities - no dumpsters left in your driveway overnight.

Attic Sanitizing & Decontamination
Attic sanitizing applies EPA-registered disinfectants to neutralize hantavirus, leptospirosis, salmonella, and other pathogens present in rodent waste. You need this after any confirmed rodent activity, not just visible droppings, because urine traces fluoresce under UV light even when surfaces look clean. We use enzyme-based cleaners followed by botanical disinfectants where homeowners have chemical sensitivities, and we treat every surface including the inaccessible corners where roof rats establish latrines. Our documented photo record includes UV-light documentation so you can see what was treated, not just what we say was treated.

Rodent Proofing & Exclusion
Rodent proofing, also called exclusion, is the sealing of all entry points larger than one-quarter inch - the width a juvenile roof rat needs to squeeze through. You need this after trapping and cleaning, or better yet, before rodents ever access your attic, because trapping without sealing simply creates a revolving door. Our Attic Cleaning & Rodent Proofing - Burbank technicians use the same galvanized steel mesh, concrete patching, and copper wool at pipe penetrations; we never use spray foam alone, which rats chew through in days. We inspect rooflines, eave gaps, chimney flues, garage attic transitions, and the often-overlooked gaps where HVAC lines enter through soffits. Every sealed point is photographed and noted in your written scope.

Attic Restoration
Attic restoration is the complete rebuild after contamination: cleanout, sanitizing, structural repairs, and new insulation installed to current Title 24 standards. You’ll need this when contamination is widespread, when insulation has lost its R-value due to compression or moisture, or when you’re preparing to sell and need documentation of professional remediation. We install Owens Corning or Johns Manville insulation products matched to your home’s needs, and we never blow new material over an unsealed attic floor - air sealing of top plates, can lights, and penetrations comes first. Your final documentation includes before-and-after photos, the written warranty, and blower-door readings where applicable so you can verify the performance change.

Brands We Service for Attic Cleaning & Rodent Proofing

We’ve worked extensively with Owens Corning insulation systems, particularly their AttiCat blown-in fiberglass and ProPink Loosefill products that we install in Glendale homes after cleanout and sealing. Their formaldehyde-free composition holds up well in our dry climate, and we stock their baffles and vent chutes for proper attic ventilation after restoration. We’ve also installed Johns Manville Climate Pro blow-in fiberglass in hundreds of local attics; their binder technology resists settling in the temperature swings that Glendale attics experience between 110°F summer afternoons and 45°F winter nights.
Whether your attic currently contains Owens Corning, Johns Manville, GreenFiber, Demilec, or any other insulation brand - or a patchwork of materials installed by previous owners over decades - we can assess, remove, and replace with products matched to your home’s specific thermal needs. We carry no proprietary lock-in; our material recommendations are based on your attic’s condition, your budget, and the written scope we deliver before work begins.
Before
AfterSigns You Need Attic Cleaning & Rodent Proofing Right Now
- Nocturnal scratching or scurrying sounds above ceiling drywall. Roof rats are most active between 10 p.m. and 4 a.m., and Glendale’s mature tree canopy gives them continuous overhead travel routes into attic vents and eave gaps. If you’re hearing regular movement, you likely have an established colony rather than a single intruder, which means contamination is accumulating and entry points are being actively used.
- Visible droppings or urine stains on attic insulation or stored items. Rat droppings are spindle-shaped and roughly half an inch long; mouse droppings are smaller and rod-shaped. Both contain pathogens that become airborne when disturbed, which is why we use HEPA containment during cleanout. In Glendale’s dry climate, old droppings desiccate and crumble, increasing inhalation risk during any attic access.
- Ammonia or musky odor that intensifies in warm weather. Rodent urine crystallizes and reactivates with heat, which means Glendale’s August afternoons can make a contained attic problem suddenly noticeable throughout the house. If you smell it in a second-story hallway or near ceiling light fixtures, the contamination layer is likely extensive enough to require full cleanout.
- Insulation that appears tunneled, compressed, or discolored. Roof rats create runways through fiberglass batts and use shredded material for nesting, reducing your insulation’s effective R-value by 30% or more in affected areas. We see this frequently in Glendale’s 1950s ranch homes where original insulation has never been replaced and has become both habitat and highway.
- Daylight visible through roof or eave gaps from inside the attic. Any gap that passes light passes rodents, and Glendale’s combination of seismic settling, sun-degraded flashing, and original construction shortcuts creates more of these than most homeowners realize. We document every penetration during inspection and seal with materials rated for the specific location - not caulk that cracks, not foam that chews.
Our Attic Cleaning & Rodent Proofing Process - Step by Step

- 1
Inspection and written scope. We arrive with UV lights, moisture meters, and inspection cameras to assess contamination extent, identify all entry points, and photograph conditions. Within 24 hours, you receive a written price with line-item breakdown - cleanout, sanitizing, exclusion, restoration - and no work starts until you approve in writing. This is Haven Standard Clause 1, non-negotiable.
- 2
Containment and HEPA cleanout. Our crew seals attic access points to your living space with plastic sheeting and negative-air machines, then removes all contaminated material using HEPA-filtered vacuums and double-bagged containment. We work methodically from the far corner toward the access hatch to avoid tracking contamination through your home. Every bag is sealed and transported to licensed waste facilities.
- 3
Structural sanitizing and deodorizing. We apply EPA-registered disinfectants to all wood surfaces, joist bays, and ductwork using low-pressure sprayers that saturate without overspray. Enzyme treatments break down organic matter in porous wood; botanical alternatives are available for chemically sensitive households. UV-light verification confirms coverage before we proceed.
- 4
Rodent exclusion and air sealing. Using galvanized steel mesh, concrete patch, copper wool, and rigid flashing, we seal every entry point identified during inspection. We also complete air sealing of top plates, can lights, and plumbing/electrical penetrations - the same gaps that leak conditioned air also admit rodents. This dual-purpose work is documented with photos of each sealed location.
- 5
Restoration, final documentation, and warranty delivery. Where restoration is included, we install new insulation to Title 24 compliance after air sealing is complete. You receive your documented photo record, written warranty under our 365-Day Done Right Promise, and where applicable, before-and-after blower-door readings showing the measurable change in envelope leakage. Wes Okafor reviews every documentation packet before it leaves our office.
How Much Does Attic Cleaning & Rodent Proofing Cost in Glendale?
A typical attic cleanout and sanitizing in Glendale runs $1,200-$2,400 for attics under 1,000 square feet with moderate contamination. Rodent proofing and exclusion for a single-family home with standard roofline complexity adds $800-$1,800. Full attic restoration - cleanout, sanitizing, exclusion, plus new insulation installation - typically ranges from $3,500 to $6,500 depending on attic size, insulation type, and whether structural repairs are needed.
Several factors move these numbers. Attic accessibility matters: a hatch in a closet versus a pull-down stair versus a cut-in access through drywall each affects labor hours. Contamination depth determines whether surface sanitizing suffices or full removal is required - we’ve found attics in the Rossmoyne Historic District with four layers of degraded insulation dating to 1947. Roof complexity affects exclusion pricing; a simple gable roof has fewer entry vectors than a multi-plane design with dormers and multiple vent types. And the insulation you choose for replacement - Owens Corning fiberglass, Johns Manville, or GreenFiber cellulose - has different material costs per square foot at equivalent R-values.
To avoid overpaying, get any competing estimate in writing and bring it to us for a Free Second Opinion. We’ll read it with you line by line and flag scope gaps we’ve seen from other Glendale contractors - common ones include quoting cleanout without exclusion (the rats return), or quoting insulation replacement without air sealing (you pay for R-value you don’t actually get because air is still moving freely). Our estimate includes everything needed to solve the problem completely, with no surprise add-ons after work begins.
Every estimate is free, delivered in writing, and valid for 30 days. Call (213) 474-3828 to schedule.
