Trusted Attic Cleaning & Rodent Proofing for Palo Alto Homeowners
Attic Cleaning & Rodent Proofing pricing in Palo Alto typically runs $1,800-$4,500 for a complete service including cleanout, sanitizing, exclusion, and restoration, with most jobs completed in one to three days. We answer calls live 24/7 at (650) 352-3577, and same-day appointments are often available across Palo Alto and neighboring communities.
We’ve been operating under The Haven Standard since 2016, and in that time we’ve cleaned, sealed, and restored attics in more than 9,000 homes. Attic Cleaning & Rodent Proofing in Palo Alto presents specific challenges: the mature oak canopy in neighborhoods like Old Palo Alto and Professorville supports robust roof rat populations, while the mid-century ranches in Green Acres and the Eichlers in Fairmeadow have construction details that create predictable entry points most contractors miss. Our crews are background-checked, uniformed, and trained to document every job with photos and a written scope before any work begins. We don’t start without a written price, and we don’t leave without a documented record.
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 after an infestation or years of neglect. In Palo Alto, we regularly find that homes built before 1980, common in neighborhoods like Downtown North and Southgate, contain original cellulose or early fiberglass that has compressed and harbored multiple generations of rodent activity. Our crew removes all contaminated material using HEPA-filtered vacuums and proper PPE, then hauls it away for appropriate disposal. You’ll receive photos of the empty attic deck before we proceed to the next phase.

Attic Sanitizing & Decontamination
Attic sanitizing applies EPA-registered disinfectants and enzymatic treatments to neutralize rodent urine, feces, and the pheromone trails that attract new rodents to the same locations. This step matters because roof rats in Palo Alto, particularly in areas near the Baylands and the tree corridors along San Francisquito Creek, establish scent paths that persist even after physical removal. We fog and hand-treat all surfaces, including the inaccessible corners where joists meet top plates. The product we use breaks down organic matter without leaving residual odor that would signal a chemical cover-up rather than actual decontamination.

Rodent Proofing & Exclusion
Rodent proofing, also called exclusion, is the sealing of all entry points larger than one-quarter inch with materials rodents cannot chew through: steel mesh, copper flashing, concrete patch, and rigid metal. Our crews in Palo Alto have learned to look for the less obvious breaches: the gap where a two-story Eichler’s roof meets its atrium wall, the unscreened vent in a Spanish Colonial tile roof near Crescent Park, the utility penetration in a ranch home’s soffit in Midtown. We also install proper vent screening and door sweeps where needed. Every exclusion job includes a written map of all entry points found and sealed, with photos.

Attic Restoration
Attic restoration replaces what was removed and improves what was there before, typically with new insulation installed only after complete air sealing of the attic floor. In Palo Alto’s climate zone, where summer attic temperatures exceed 140°F and winter nights drop into the 30s, the sequence matters: we seal first, then insulate. We use materials from Owens Corning, Johns Manville, Knauf, and others depending on your home’s needs and your preferences. On applicable jobs, we run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope was losing before and after our work - and we publish those numbers in your documented record.

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, which we install in many Palo Alto homes where the original insulation was removed due to contamination. Their product line integrates well with the air-sealing approach we take, and we stock the full range of R-values appropriate for California Title 24 requirements. We’ve also completed numerous restorations using Johns Manville formaldehyde-free fiberglass and mineral wool products, which perform well in the humidity variations seen near Palo Alto’s bayfront properties.
For homeowners seeking sustainable options, we regularly specify GreenFiber cellulose insulation, made from recycled paper with borate fire retardant, which we can blow into attics after our sealing work is complete and verified. Whether you have a preference for Owens Corning, Johns Manville, GreenFiber, or any other manufacturer, we source without proprietary lock-in and install to the same documented standard. Our home page details our full building-envelope service line.
Signs You Need Attic Cleaning & Rodent Proofing Right Now
- Nocturnal scratching or scurrying sounds above ceiling planes. Roof rats are active at night, and Palo Alto’s mature tree canopy provides highway access directly to your roofline. If you hear movement after dark, particularly in older homes with unscreened eave vents, you likely have active rodents that are compressing insulation, contaminating air handlers, and chewing wiring.
- Visible droppings or urine stains in attic access areas. Rodent feces carry hantavirus, leptospirosis, and salmonella; disturbing them without proper PPE and HEPA containment aerosolizes particles into living spaces. We treat this as a biohazard remediation, not a simple cleaning job.
- Uneven temperatures or rising energy bills without explanation. When rodents tunnel through insulation, they create voids that defeat the thermal barrier. In Palo Alto’s climate, where PG&E rates are among the nation’s highest, a compromised attic can add 20-30% to heating and cooling costs.
- Unpleasant odors that intensify in warm weather. Decomposing organic matter in an attic produces ammonia and sulfur compounds that penetrate drywall through light fixtures and gaps around registers. The smell often peaks in late summer when Palo Alto attics reach their highest temperatures.
- Daylight visible through roof penetrations from inside the attic. Any opening that admits light admits rodents, and roof rats need only a half-inch gap. We document every penetration during our initial inspection, whether it’s a plumbing vent boot, a deteriorated fascia joint, or an unsealed chimney chase.
Our Attic Cleaning & Rodent Proofing Process - Step by Step

- 1
Written price and scope before any work starts. We inspect your attic, identify contamination extent, map entry points, and deliver a flat price with a written scope and written warranty. This is Haven Standard Clause 1: no work begins until you have all three documents in hand. The inspection itself is free, and we offer a Free Second Opinion on any written estimate you’ve received from another contractor.
- 2
Containment and removal of contaminated materials. Our crew establishes negative air pressure where possible, wears respirators and Tyvek suits, and removes all soiled insulation, droppings, and nesting material using HEPA vacuums. We haul everything away; nothing goes in your household trash. Photos are taken every fifteen minutes of active removal.
- 3
Sanitizing and decontamination of all surfaces. We apply enzymatic treatment followed by EPA-registered disinfectant, with dwell times observed per manufacturer specification. This neutralizes pheromone trails that would otherwise draw new rodents to the same attic. We then verify with UV light inspection to identify any missed organic residue.
- 4
Air sealing and rodent exclusion. Before any new insulation goes in, we seal the attic floor: top plates, can lights, plumbing and electrical penetrations, and chimney chases. Simultaneously, we seal all exterior entry points with rodent-proof materials. On applicable jobs, we run a blower-door test to quantify the air-sealing result and publish before-and-after CFM50 readings in your documented record.
- 5
Restoration with new insulation and final documentation. We install your selected insulation to the specified depth and R-value, verify even coverage, and conduct a final walkthrough with you. You receive a Documented Photo Record of the entire job, your written warranty, and our 365-Day Done Right Promise: if it’s not done right, we make it right.
How Much Does Attic Cleaning & Rodent Proofing Cost in Palo Alto?
A typical attic cleanout and sanitizing in a 1,200-1,800 square foot Palo Alto home runs $1,800-$2,800. Adding complete rodent exclusion with entry-point sealing brings most jobs to $2,800-$4,000. Full restoration including new insulation installation after cleanout, sanitizing, and sealing typically ranges from $3,500-$4,500, with larger homes in areas like Old Palo Alto or the Professorville district sometimes exceeding this range based on attic complexity and accessibility.
Several factors move the price: attic square footage and accessibility (Eichler atriums and low-slope roofs take longer), the extent of contamination and structural damage, whether active electrical or HVAC work is needed before we restore, and the insulation type you select. We use materials from Owens Corning, Johns Manville, Knauf, and GreenFiber, and your written price specifies exactly which product and R-value you’re paying for.
To avoid overpaying, get any competing quote in writing and bring it to us for a Free Second Opinion. We’ll read it with you line by line. Our price is flat - no change orders for “surprise” contamination we should have identified in inspection. Everything is in the written scope before anyone lifts a tool.
