What Our Attic Cleaning & Rodent Proofing Service Includes
Attic Cleanout
An attic cleanout is the removal of contaminated insulation, rodent droppings, nesting debris, and any stored items that block access or harbor pests. In Attic Cleaning & Rodent Proofing in Atherton and Menlo Park, we regularly find that homes built before 1980 - common in the downtown and Felton Gable neighborhoods - have original insulation mixed with decades of rodent activity that homeowners never knew existed. Our crew removes all debris using HEPA-filtered vacuums and proper PPE, then hauls everything away so the space is ready for sanitizing or re-insulation. We document the condition with photos before we touch anything, and those images are included in your job record.
Attic Sanitizing & Decontamination
Attic sanitizing and decontamination eliminates the bacteria, viruses, and pheromones left behind by rodents, which otherwise attract new pests even after the original infestation is gone. We apply an EPA-registered disinfectant to all affected surfaces, including joists, decking, and ductwork, and we pay special attention to Menlo Park’s frequent issue: flexible duct runs in older ranch homes that rodents use as highways between attic zones. The sanitizing step also neutralizes the urine proteins that trigger allergies and asthma, a documented concern in homes with children. Your crew lead will note which areas required heavy treatment and photograph the completed work.
Rodent Proofing & Exclusion
Rodent proofing and exclusion means sealing every entry point larger than 1/4 inch - the width a mouse needs - and installing barriers at common breach points like roof vents, eave gaps, and plumbing penetrations. In Menlo Park and nearby Attic Cleaning & Rodent Proofing in Stanford, we see consistent patterns: Spanish tile roofs in the Sharon Heights area create gap networks that roof rats exploit, while the mature oak canopy in Allied Arts provides highway access to eaves that homeowners never inspect. We use steel mesh, concrete patching, and purpose-built exclusion hardware, never spray foam alone (rodents chew through it). Every sealed point is photographed and mapped on your job documentation.
Attic Restoration
Attic restoration returns your attic to a clean, thermally functional state after contamination or damage has been removed and entry points sealed. For Menlo Park homes, this often means reinstalling insulation to current Title 24 standards, which we verify with a blower-door test - a pressurization reading that shows, in one number, how much conditioned air your building envelope was losing before and after our work. We source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so your replacement insulation matches your performance goals and budget without proprietary lock-in. The restoration phase ends with a written scope completion sign-off and your Documented Photo Record.

Brands We Service for Attic Cleaning & Rodent Proofing
We’ve worked extensively with Rockwool insulation products in Menlo Park attics, particularly in homes where fire resistance and sound dampening are priorities alongside thermal performance. Rockwool’s mineral wool composition handles the high-density reinstalls common in restoration jobs without settling, and our crews are trained in its specific handling requirements for both removal and reinstallation. We’ve also specified CertainTeed fiberglass systems for homeowners who want a cost-effective replacement with proven vapor management in Menlo Park’s marine-influenced climate.
For spray foam restoration applications, we regularly install Icynene open-cell systems in Menlo Park’s newer construction and selective Demilec closed-cell products where moisture control and structural rigidity are both required, such as in converted attics with limited ventilation. Whether your original insulation was Rockwool, CertainTeed, Icynene, Demilec, or any other make, we can match or upgrade the system based on what your attic actually needs. We carry no exclusive brand relationships - the material choice follows the building science, not a sales quota.
Before
AfterSigns You Need Attic Cleaning & Rodent Proofing Right Now
- Insulation appears flattened, tunneled, or displaced. Rodents compress and redistribute insulation to create nesting cavities, which destroys the material’s R-value and creates uneven temperature zones in your living space. In Menlo Park’s Eichler and ranch-style homes with open attics, this damage spreads quickly because there’s no vertical barrier to contain it.
- You hear scratching or movement overhead, especially at dusk or dawn. Roof rats and mice are crepuscular, meaning they’re most active during twilight hours, and attics provide ideal nesting territory away from human activity. Ignoring these sounds typically leads to breeding populations and exponentially more contamination within 60-90 days.
- Musty or ammonia-like odors are noticeable indoors, particularly when the HVAC runs. Rodent urine contains volatile compounds that penetrate flexible ductwork and seep through ceiling penetrations, especially in homes with central returns located in the attic plenum. This is a health concern, not merely an odor problem.
- Droppings are visible in the attic, around the perimeter of the house, or near entry points. Fresh droppings are dark and moist; older ones are gray and crumbly. Finding either means active or recent infestation, and the location pattern tells us where rodents are traveling and potentially entering.
- Your energy bills have risen without explanation or rooms feel drafty despite closed windows. Compromised insulation and air leaks created by rodent damage allow conditioned air to escape and unconditioned attic air to infiltrate. A blower-door test can quantify this loss precisely, and we provide those numbers on applicable jobs.
Our Attic Cleaning & Rodent Proofing Process - Step by Step
- 1
Inspection and documentation. We photograph your attic’s current condition, identify contamination zones, map active and potential rodent entry points, and test for airborne particulates if heavy droppings are present. You receive a written scope and flat price before any work begins - Haven Standard Clause 1, no exceptions.
- 2
Contaminant removal and cleanout. Using HEPA-filtered vacuums and sealed disposal containers, we remove all contaminated insulation, droppings, carcasses, and nesting material. In Menlo Park’s older homes with original blown-in fiberglass, this step often reveals hidden leaks around chimneys and top plates that we note for the air-sealing phase.
- 3
Sanitizing and decontamination. We apply EPA-registered disinfectant to all affected structural surfaces, with extended dwell time in heavily contaminated zones. Flexible ductwork is inspected for damage; if rodents have breached the interior, we flag replacement needs in your written scope rather than conceal the problem.
- 4
Exclusion and rodent proofing. Every gap 1/4 inch or larger is sealed with rodent-resistant materials: steel mesh for weep holes and vents, concrete or metal flashing for larger breaches, and hardware cloth for vent screens. We focus on the roofline, eave junctions, and utility penetrations where Menlo Park’s mature tree canopy provides access.
- 5
Restoration, testing, and documentation. Insulation is reinstalled to specified depth and density; on jobs including air sealing, we run a blower-door test and publish the before-and-after CFM50 reading. You receive a Documented Photo Record of all work phases, a written warranty, and your 365-Day Done Right Promise documentation.
How Much Does Attic Cleaning & Rodent Proofing Cost in Menlo Park?
A typical attic cleanout and sanitizing in Menlo Park runs $1,800-$2,800 for attics under 1,200 square feet with moderate contamination. Adding full rodent proofing and exclusion brings most jobs to $2,800-$4,000, depending on roof complexity and the number of entry points we identify. Complete attic restoration - cleanout, sanitizing, exclusion, and insulation replacement - typically ranges from $3,500-$4,500 for standard Menlo Park ranch and Eichler footprints, with larger or heavily contaminated attics extending toward $6,000.
Several factors move the price: attic accessibility (some Menlo Park hillside homes have hatches too small for standard equipment), the type and depth of existing insulation, whether HVAC ductwork has been breached and requires replacement, and the extent of air sealing needed before new insulation goes in. We never blow insulation over an unsealed attic floor - our crews seal top plates, can lights, and penetrations first, then insulate. That sequencing adds labor but prevents the trapped moisture and thermal bypass problems that require rework later.
Every estimate we provide is a written, flat price with a detailed scope - no open-ended hourly rates, no material markups revealed mid-job. We also offer a Free Second Opinion on any written estimate from another contractor; bring us their scope and we’ll review it line by line. To avoid overpaying, get at least one competing quote in writing, verify that sanitizing is included (not just removal), and confirm that exclusion work carries its own warranty period separate from any insulation warranty.

Attic cleaning and rodent proofing is a multi-phase service that removes contaminated materials, sanitizes the space, seals all rodent entry points, and restores thermal performance.

Your crew lead will call or text when en route, under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
