Trusted Attic Cleaning & Rodent Proofing for West Hollywood Homeowners
Attic Cleaning & Rodent Proofing - West Hollywood typically costs between $1,200 and $4,500 depending on contamination level, attic square footage, and whether structural repairs are needed. Most projects are completed in 1-3 days, and we can often start within 48 hours of your call. Topside Attic Insulation West Hollywood has handled attic cleanouts and rodent exclusions in this market since 2016, from compact 1920s Spanish bungalows near Santa Monica Boulevard to multi-level homes in the Hills.
We’re the local team that treats air sealing as a hard prerequisite, not an upsell. Before we add any new insulation, we seal top plates, can lights, and penetrations so rodents can’t re-enter and conditioned air stays where it belongs. Every job starts with a written price and ends with a Documented Photo Record. Call (213) 306-2607 to schedule your free estimate.
What Our Attic Cleaning & Rodent Proofing Service Includes
Attic Cleanout
An attic cleanout is the removal of contaminated insulation, rodent droppings, nesting material, and debris that accumulates over years of pest activity. In West Hollywood, we regularly find this problem in homes between Laurel Canyon and Fountain Avenue where mature trees provide roof access for rats and squirrels. Our crew removes all unsalvageable material down to the attic floor, then bags and hauls it according to Los Angeles County biohazard disposal protocols. You’ll receive before-and-after photos showing the full extent of the removal.

Attic Sanitizing & Decontamination
Attic sanitizing and decontamination applies EPA-registered disinfectants to eliminate hantavirus, leptospirosis, and salmonella risks left behind by rodent waste. This step is non-negotiable after any confirmed infestation, even if the droppings appear old or dry. We use a commercial fogging system that reaches joist bays and eave corners where hand-wiping can’t, then apply an enzymatic treatment that breaks down organic matter at the molecular level. The attic is ventilated and moisture-tested before any new materials go in.

Rodent Proofing & Exclusion
Rodent proofing and exclusion means sealing every entry point larger than 1/4 inch, the gap width a young rat can squeeze through. We inspect roof junctions, vent screens, soffit gaps, plumbing penetrations, and the garage-to-attic chase common in West Hollywood’s mid-century apartment conversions and single-family homes. Our crews use galvanized steel mesh, concrete patching, and chew-resistant sealants, not spray foam that rodents can tunnel through in weeks. Every exclusion includes a 365-Day Done Right Promise under Haven Standard: if they get back in, we come back out.

Attic Restoration
Attic restoration rebuilds your thermal and air barrier after contamination has been removed and entry points sealed. This typically means installing new blown-in insulation, often Owens Corning or Johns Manville fiberglass, at R-38 to R-49 depth per California Title 24 requirements for West Hollywood’s climate zone. We complete blower-door-guided air sealing first, then insulate, then run a final blower-door test so you see the pressurization improvement in one number. The written scope, warranty, and photo record are delivered before the crew leaves.

Signs You Need Attic Cleaning & Rodent Proofing Right Now

- Scratching or scurrying sounds during early morning or evening hours. Rodents are crepuscular, meaning most active at dawn and dusk. If you’re hearing movement overhead while you’re still in bed or just getting home from work on the Sunset Strip, you likely have active tenants. The longer they stay, the more insulation they compress and contaminate.
- Urine stains or droppings on attic access panels or in ceiling fixtures. Rat droppings are spindle-shaped, roughly 1/2 to 3/4 inch long; mouse droppings are smaller and rod-shaped. Finding these near recessed can lights is especially common in West Hollywood’s flat-roofed modern homes where attic space is minimal and rodents travel along electrical runs. This contamination circulates through your HVAC if the air handler is in the attic.
- Sudden spikes in heating or cooling bills without equipment changes. Compressed or displaced insulation loses R-value fast. A rodent nest the size of a football can flatten batt insulation across several square feet, creating thermal bypasses that your system works overtime to overcome. We’ve measured attic floors in the Norma Triangle where 40% of the insulation volume had been tunneled through.
- Visible daylight through roof gaps or chewed vent screens from inside the attic. These are active entry points, not just old damage. West Hollywood’s combination of mature ficus canopy, tile roofs with broken or shifted pieces, and close-set neighboring structures gives rodents multiple highway options. Every gap you can see from inside is one they already know about.
- Unexplained odors that worsen on hot days. Decomposing rodent waste and, in worst cases, carcasses produce ammonia and sulfur compounds that intensify as attic temperatures climb past 120°F in August. If your second floor smells musty or sour and the source isn’t plumbing, the attic is the next place to check. This odor also indicates active bacterial breakdown that affects indoor air quality.
Before
AfterOur Attic Cleaning & Rodent Proofing Process - Step by Step
- 1
On-site inspection and written price. We arrive with a ladder, respirator, and camera. The technician photographs contamination, measures attic square footage, identifies entry points, and runs a moisture meter on any stained decking. Within 24 hours you receive a flat written price with scope, warranty, and timeline. No work starts without it. Haven Standard Clause 1.
- 2
Attic cleanout and hazardous material removal. Crews in full PPE remove all contaminated insulation, droppings, nests, and debris. We use HEPA-filtered vacuums and negative air machines when contamination is extensive. Material is double-bagged and disposed of through licensed biohazard haulers. You get photos of the empty attic deck before sanitizing begins.
- 3
Sanitizing, decontamination, and drying. Commercial fogger applies disinfectant to all surfaces including sheathing, joists, and ductwork. Enzymatic treatment follows for heavy organic loading. We run axial fans until moisture content reads below 19% on the wood, preventing mold growth before new insulation goes in.
- 4
Rodent proofing and exclusion. Every gap 1/4 inch or larger is sealed with appropriate materials: 1/2-inch hardware cloth for vents, concrete patch for masonry gaps, galvanized flashing for roof junctions, chew-resistant sealants for irregular penetrations. We pay special attention to the chimney chase and kitchen vent stacks where West Hollywood’s older homes often have deteriorated flashing.
- 5
Air sealing, insulation, and documentation. Top plates, wire penetrations, and can light boxes are sealed with fire-rated foam and tape. New insulation is installed to specified depth. On applicable jobs, we run before-and-after blower-door tests and publish the CFM50 readings so you can verify the air-sealing result. The Documented Photo Record, written warranty, and final invoice are delivered before we leave.
How Much Does Attic Cleaning & Rodent Proofing Cost in West Hollywood?

A typical attic cleanout and sanitizing in West Hollywood runs $1,200-$2,800 for a 1,000-1,500 square foot attic with moderate contamination; see our Attic Cleaning & Rodent Proofing pricing page for more detail. Add rodent proofing and exclusion, and most projects fall between $2,400-$4,500 total. Attic restoration with new insulation adds $1.80-$3.20 per square foot depending on material, Owens Corning fiberglass blown-in at R-38 being the most common choice in this market.
What moves the price:
- Contamination severity. Light droppings confined to one corner clean faster than saturated insulation requiring full removal.
- Attic accessibility. West Hollywood’s hillside homes on streets like Rising Glen or Kirkwood often have hatches too small for standard equipment, requiring hand-carry or crane rental.
- Entry point complexity. A single chewed vent screen is straightforward; multiple roof-level gaps on a multi-plane tile roof take longer to seal properly.
- Structural damage. Urine-soaked decking that has delaminated requires replacement before new insulation can be installed.
How to avoid overpaying: get a written scope that specifies square footage, material type by brand name, and whether air sealing is included. Some competitors in the West Hollywood market quote low on cleanout, then treat sealing as a separate line item. Our price covers the complete envelope repair.
