Trusted Attic Cleaning & Rodent Proofing for West Hollywood Homeowners
Attic cleaning and rodent proofing in West Hollywood typically costs between $850 and $2,400 depending on attic size, severity of contamination, and how much exclusion work is needed. Most jobs in West Hollywood are completed in one day, and homeowners who call (213) 527-4062 get a live person on the line, not a voicemail. Walt’s Insulation has been cleaning attics and sealing rodents out of homes since 2000, and Walt Brenner still runs the company himself.
If you hear scratching above your ceiling at night in the Norma Triangle or noticed droppings in your insulation near the Design District, you’re dealing with a problem that won’t fix itself. Rats, mice, and squirrels tear through insulation, chew wiring, and leave behind waste that makes the air you breathe inside your home worse than the air outside. We handle the full job: cleanout, sanitizing, proofing, and restoration. Same-day and next-day appointments are available throughout West Hollywood.
What Our Attic Cleaning & Rodent Proofing Service Includes
Every attic we service in West Hollywood gets a complete inspection first. We look at the insulation, the wiring, the ductwork, the roof decking, and every possible entry point. Then we give you a straightforward plan with upfront pricing, not a vague estimate that balloons after the work starts. Here is exactly what each part of the job covers.
Attic Cleanout
An attic cleanout means removing contaminated insulation, old nesting material, droppings, and whatever else rodents dragged in. In West Hollywood, where many homes were built between the 1920s and 1960s, we often find old fiberglass batts mixed with rat tunnels and years of accumulated dust. We bag everything, vacuum the entire attic floor with HEPA filtration, and haul it all away so nothing contaminated stays in your house.
You need a full cleanout when droppings are visible, when insulation has been flattened into greasy runways, or when you smell a musky odor that gets stronger on warm days. This is not a surface-level tidy-up. We take the attic down to the decking in most cases so the sanitizing step actually works. Skipping the cleanout and just laying fresh insulation over the mess is something we refuse to do, because it locks the problem in.
Walt’s Insulation sends background-checked, uniformed technicians to do the work, so the people in your attic are people you can trust. We protect your home during the job with floor runners and plastic barriers. When we leave, the attic is empty, swept, and ready for the next step.
Attic Sanitizing & Decontamination
Sanitizing is where the health benefit really comes in. Rodent urine and feces carry pathogens that become airborne when they dry out and get pulled into your living space through ceiling gaps and recessed lights. We apply an enzyme-based treatment that breaks down organic waste rather than just covering the odor with fragrance. That matters for anyone in the house with allergies, asthma, or a sensitive immune system.
In West Hollywood’s dry climate, attic dust hangs around longer and gets pulled through the house every time your HVAC cycles. A proper decontamination means treating the decking, the rafters, the ducts’ outer surfaces, and any interior wall cavities where nesting existed. We also check the insulation in adjacent areas to make sure contamination did not spread beyond the obvious spots.
This step is part of a bigger commitment: our Done Right Promise. If we sanitize your attic and the odor comes back because we missed something, we come back and fix it. That guarantee is lifetime and it is in writing. Walt Brenner has never backed away from a callback in over 25 years.
Rodent Proofing & Exclusion
Cleaning and sanitizing without sealing the entry points just sets the table for the next family of rats to move in. Exclusion, done right, means finding every gap that a rodent could fit through, which is anything the width of a dime or larger. We inspect the roofline, the eaves, the vent screens, the pipe penetrations, the AC line chases, and the gaps around brick and stucco.
Most West Hollywood homes have vulnerabilities at the transition between the roof and the walls, especially on older Spanish and Mediterranean styles where clay tile roofs leave gaps at the edges. We seal these with professional-grade materials: galvanized steel mesh, metal flashing, and pest-blocking sealants. We do not use spray foam as a primary rodent barrier, because rodents chew through it. The materials we use last, which is why our work carries the same Done Right Promise.
Once the entry points are sealed, we do a final sweep to confirm nothing is trapped inside. The last thing you want is a sealed-in rodent dying in a wall cavity. If there is any sign of active activity, we set professional traps and return to check them before closing the job.
Attic Restoration
Restoration is about returning your attic to a clean, functional, and efficient state. After the cleanout, sanitizing, and exclusion, we install fresh insulation to bring the attic up to current standards. This is where the brands we work with come in. Whether we’re blowing in Owens Corning fiberglass or installing Rockwool batts, the material goes in correctly, at the right depth, with proper ventilation maintained.
For many West Hollywood homes, we recommend air sealing alongside the new insulation. Light fixture boxes, top plates, and plumbing penetrations leak conditioned air into the attic year-round. Sealing those gaps makes a measurable difference in your energy bill and keeps the attic from pulling dusty air through your ceiling.
The result is an attic you could walk through barefoot, no contaminants, no animal smells, no sagging insulation, and no way for rodents to get back in. That is the standard we’ve held since 2000, and it is why homeowners from the Sunset Strip to the Beverly Hills border call us back when they move to a new house.

Brands We Service for Attic Cleaning & Rodent Proofing
We’ve worked with Owens Corning insulation in hundreds of West Hollywood attics over the past 25 years. Their blown-in fiberglass is what we install most often after a cleanout because it settles evenly, resists moisture, and performs consistently in Southern California’s heat. We spec the right R-value for your attic based on Department of Energy guidelines for the West Hollywood climate zone, and we install it at the correct density so you get the performance the material is rated for.
Rockwool batts are another common choice, especially for homeowners who want fire-resistant insulation in the attic. Stone wool does not burn, which is a meaningful safety feature in older West Hollywood homes where wiring may be dated. And when moisture is a concern, we turn to Johns Manville products, which hold up well in attic spaces with limited ventilation. No matter what brand is currently in your attic, or what you want installed after the cleanout, we have hands-on experience with it. If you have a different material you prefer, we will work with that too.
Attic Cleaning & Rodent Proofing in West Hollywood is one of the core services we built our reputation on. It also pairs naturally with home energy improvements that save you money year after year.
Signs You Need Attic Cleaning & Rodent Proofing Right Now
- Scratching, scurrying, or thumping sounds at night. Rodents are nocturnal, so the noise tends to start right after sunset. In West Hollywood, roof rats are the most common culprit, and they prefer upper levels and attics. The sound may come from directly above your bedroom or travel through wall cavities. This is the most reliable early sign, and the earlier you respond, the less damage you are dealing with.
- Droppings in the attic or around exterior entry points. Rat droppings are about the size of a raisin and dark with pointed ends. Mouse droppings are smaller, like a grain of rice. You might find them along the attic perimeter, near stored boxes, or on top of the insulation. Droppings mean active occupation, not a one-time visitor.
- Greasy rub marks and flattened insulation runways. Rodents travel the same paths over and over, leaving oil from their fur along beams, pipes, and junction boxes. You will see dark smudges where they squeeze through gaps. Insulation that looks trampled in lines is a signature of rodent traffic, not normal settling.
- An unexplained musky or ammonia-like smell in the hallway or bedrooms. Urine and nest materials have a distinct smell that intensifies with heat. On hot Santa Ana days, many West Hollywood homeowners first notice the odor from attic contamination because the heat bakes the waste. If air fresheners are not fixing the smell, the source is probably above you.
- Chewed wires, damaged ductwork, or missing insulation patches. Rodents gnaw constantly to keep their teeth from overgrowing, and electrical wire insulation is a favorite target. This is a fire hazard, plain and simple. If you see exposed copper or insulation that looks shredded, do not wait. This is the point where a cleaning service becomes an urgent safety repair.
Our Attic Cleaning & Rodent Proofing Process - Step by Step
- 1
Inspection and written estimate. We start by walking the attic, the roof, and the property perimeter. Walt or one of our lead technicians looks at every entry point, checks for active nesting, assesses the insulation’s condition, and takes photos you can see. Then you get a written estimate with a clear price before you agree to anything. No vague range, no surprise fees.
- 2
Cleanout and removal. On the scheduled day, we protect the interior walkways with floor runners, set up containment barriers, and remove all contaminated insulation, nesting, droppings, and debris. We use commercial HEPA vacuums to clean the decking and all horizontal surfaces. Every bag of waste is removed from your property the same day, not left by the curb for you to deal with.
- 3
Sanitizing and decontamination. Once the attic is empty, we apply our enzyme-based sanitizing treatment to all affected surfaces. This step neutralizes odor at the source and reduces the pathogen load from dried urine and feces. We let the treatment dwell for the correct amount of time to do its job, then verify the attic is clean and dry before moving on.
- 4
Exclusion and sealing. Now we close every opening we found during inspection, using steel mesh, flashing, and professional sealants. This step is what separates a real rodent proofing job from a cleaning that just buys you six months. Every vent, gap, and crack gets sealed properly, and any active entry point is trapped and monitored before the final closure.
- 5
Restoration and final walkthrough. We install new insulation to the correct R-value, air seal the attic floor where needed, and reset any displaced venting. Then we walk the attic with you or send photos so you can see the finished work. You get a clear explanation of everything we did and the lifetime Done Right Promise on workmanship.
How Much Does Attic Cleaning & Rodent Proofing Cost in West Hollywood?
A typical attic cleanout with sanitizing and basic Attic Cleaning & Rodent Proofing pricing in West Hollywood runs between $850 and $1,800 for a standard single-family home. If full exclusion is needed because the roof has multiple entry points, or if the attic is large and heavily contaminated, the total can be $2,000 to $2,400. Restoration with new insulation typically runs $1,200 to $3,800 on top, depending on the attic’s square footage and the R-value you choose.
| Service | Typical Cost in West Hollywood |
|---|---|
| Attic cleanout only | $500-$900 |
| Sanitizing & decontamination | $300-$500 |
| Rodent proofing & exclusion | $400-$1,200 |
| Attic restoration with new insulation | $1,200-$3,800 |
What affects the price most is the size of the attic, how long the rodents have been in there, and how many entry points need sealing. A 1,200-square-foot attic with light contamination is a half-day job. A 2,500-square-foot attic with years of nesting and six open entry points takes longer and costs more, for good reason. You avoid overpaying by getting a written estimate with a clear scope of work, which is exactly what we give you. Our estimates are free, and we offer a free second opinion on any written estimate you have. There is no trip charge inside our service county, and seniors and veterans always get 10% off.

Frequently Asked Questions - Attic Cleaning & Rodent Proofing in West Hollywood
Attic cleaning and rodent proofing is the process of removing contaminated insulation and animal waste from your attic, sanitizing the space, sealing every entry point rodents can use, and restoring the attic with fresh insulation. It is a health and safety service as much as a pest control service. In West Hollywood, where roof rats are common and homes are close together, the exclusion step is what keeps the problem from returning. The full job leaves your attic clean, sealed, and properly insulated.
Most attic cleaning and rodent proofing jobs in West Hollywood are completed in one day, though heavily contaminated or larger attics may take two. A typical 1,500-square-foot attic with moderate contamination takes our crew about six to eight hours including cleanup.
