Attic cleaning and rodent proofing in Mountain View typically costs between $1,800 and $4,500 depending on contamination level and attic size, with most projects completed in one to three days. We remove soiled insulation, sanitize affected areas, seal all entry points, and restore your attic to a clean, efficient condition. Call (669) 259-0406 for a written estimate before any work starts.
We’ve provided Attic Cleaning & Rodent Proofing - Mountain View since 2016, from the Eichler neighborhoods off Cuesta Drive to the newer builds near North Bayshore. The combination of mild winters, mature oak and fruit trees, and homes with raised foundation vents creates conditions where roof rats and mice find their way into attics year-round. Once inside, they compress insulation, leave droppings that degrade air quality, and chew wiring that creates fire risk. Our crews are background-checked, uniformed, and arrive with a written scope, a flat price, and a documented photo record. We’re independently owned and operated under The Haven Standard, and a live person answers our phones 24/7.
What Our Attic Cleaning & Rodent Proofing Service Includes
Attic Cleanout
An attic cleanout is the physical removal of contaminated insulation, debris, and organic waste that rodents leave behind. In Mountain View, we commonly find this problem in homes near the Permanente Creek corridor and the older neighborhoods off Central Expressway, where mature tree canopies give roof rats easy access to eaves and roof lines. Our crew vacuums out all loose-fill and batt insulation using commercial HEPA-filtered extraction equipment, bags it for proper disposal, and hauls it away. You receive before-and-after photos showing the full extent of what was removed and the clean substrate beneath.
Attic Sanitizing & Decontamination
Attic sanitizing applies EPA-registered disinfectants to kill bacteria, viruses, and parasites carried in rodent urine and droppings, including the hantavirus and leptospirosis risks present in Santa Clara County. We use atomizing foggers and direct-contact application to reach every joist bay, duct surface, and top plate in the attic. The process matters because disturbed droppings without proper wetting and disinfection can become airborne during re-insulation. Our Mountain View crews complete this step with documented photo verification before any new materials go in, and we provide a written clearance note for your records.
Rodent Proofing & Exclusion
Rodent proofing, also called exclusion, is the sealing of every entry point larger than one-quarter inch, the gap a mouse needs, or one-half inch for a young rat. We inspect roof junctions, vent screens, pipe penetrations, eave gaps, and foundation vents, replacing deteriorated materials with galvanized steel mesh, concrete patching, and rigid metal flashing where appropriate. In Mountain View’s hilly terrain near Monta Loma and the slopes above Rengstorff Park, settling foundations often open new gaps that original construction never anticipated. Our exclusion work carries a written warranty, and we document every sealed point with photos mapped to your home’s layout.
Attic Restoration
Attic restoration returns the space to a thermally effective, code-compliant condition after cleaning and exclusion are complete. We install new insulation to the specified R-value, currently R-38 to R-60 for attics in Climate Zone 3 where Mountain View sits, using blown-in fiberglass or cellulose from manufacturers like Owens Corning and Johns Manville. Because we treat air sealing as a hard prerequisite, not an upsell, we seal top plates, can light housings, and all penetrations with fire-rated caulk and rigid foam before any insulation goes in. You receive a written scope, a flat price, and on applicable jobs, before-and-after blower-door numbers showing the actual air-leakage reduction.

Brands We Service for Attic Cleaning & Rodent Proofing
We work with insulation and building envelope materials from Owens Corning, Johns Manville, Knauf, and Rockwool, among others. Owens Corning’s blown-in fiberglass, particularly the ProCat line, handles well in the tight joist bays common in Mountain View’s mid-century homes and resists compression if rodents return before exclusion is complete. We’ve installed thousands of bags across Santa Clara County and stock it for same-day restoration starts.
Johns Manville’s Spider blown-in fiberglass bonds on contact and fills irregular cavities without settling, which matters in older Mountain View attics where framing isn’t always on standard centers. Rockwool’s mineral wool batts go in where we need rigid, cut-to-fit pieces around recessed lighting or chimney chases. Whether your existing insulation is Owens Corning, Johns Manville, Knauf, Rockwool, or any other make, we can remove it safely, assess what remains, and specify replacement that matches your home’s needs and your budget.
Signs You Need Attic Cleaning & Rodent Proofing Right Now
- Nocturnal scratching or scurrying sounds above ceiling drywall. Roof rats are most active between dusk and dawn, and Mountain View’s mild climate means they don’t slow down in winter the way they do in colder regions. If you hear movement in the attic after dark, you likely have active inhabitants that are compressing insulation, contaminating air handlers, and widening entry gaps with constant gnawing.
- Visible droppings or urine stains on insulation or framing. Rodent droppings resemble dark rice grains, and fresh ones are soft enough to indent under light pressure. In attics with ducted HVAC systems, contaminated air can pull particulates through ceiling penetrations and into living spaces, degrading indoor air quality in ways standard filters won’t catch.
- Insulation that appears flattened, tunneled, or displaced from uniform coverage. Rats and mice travel the same paths repeatedly, creating visible runways through loose-fill or compressed channels in batt insulation. This destroys the thermal boundary your home depends on, and in Mountain View’s variable climate, that means higher cooling loads in summer and heat loss on foggy winter mornings.
- Chewed wiring, PVC vent pipes, or wood framing with fresh sawdust below. Rodent incisors grow continuously, and gnawing is how they file them down. Exposed wiring with compromised sheathing is a documented fire hazard, and we’ve found chewed condensate drain lines in Mountain View attics that caused ceiling water damage before the homeowner knew rodents were present.
- Unexplained increases in heating or cooling costs with no equipment changes. When insulation is compressed or displaced, your HVAC system runs longer to maintain setpoint. If your Pacific Gas & Electric bill has climbed without rate changes or thermostat adjustments, a compromised attic thermal boundary is a likely contributor, especially in homes built before 1990 with original insulation.
Our Attic Cleaning & Rodent Proofing Process - Step by Step
- 1
On-site inspection with written scope and flat price. We arrive at your Mountain View home, access the attic, and document contamination level, insulation condition, wiring status, and all visible entry points. Within 24 hours, you receive a written scope with line-item pricing, a completion timeline, and our 365-Day Done Right Promise. No work starts without your signed approval of that written price.
- 2
HEPA-filtered removal of contaminated materials. Our crew sets up containment, negative air pressure where needed, and vacuums out all soiled insulation and debris using commercial extraction equipment. We bag everything on-site and haul it for proper disposal. You receive a documented photo record showing the attic at full contamination and after complete removal.
- 3
Sanitizing and decontamination of all surfaces. We apply EPA-registered disinfectant to joists, decking, ductwork, and penetrations using atomizing equipment that reaches cavities manual spraying misses. The product dwells per manufacturer specification, then we verify coverage with UV-trace inspection. This step is documented and must read clear before restoration begins.
- 4
Comprehensive rodent exclusion and air sealing. We seal every entry point with materials rodents cannot chew: galvanized steel mesh for vents and gaps, concrete patch for foundation breaches, fire-rated caulk and rigid foam for top plates and penetrations. In Mountain View, we pay particular attention to eave gaps opened by seismic settling and to vent screens degraded by salt air from the Bay. 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, and we seal until that number drops.
- 5
Insulation restoration with documented completion. We install new insulation to code-specified R-value for Climate Zone 3, with air sealing completed first per our standard. You receive a final documented photo record, written warranty, and on jobs where blower-door testing applies, before-and-after readings showing your actual performance improvement. The crew cleans the work area, and we follow up within 30 days to confirm satisfaction.
How Much Does Attic Cleaning & Rodent Proofing Cost in Mountain View?
A typical Attic Cleaning & Rodent Proofing pricing in Mountain View starts with cleanout and sanitizing at $1,800 to $2,800 for attics under 1,200 square feet with moderate contamination. Rodent proofing and exclusion adds $800 to $1,600 depending on entry point count, roof complexity, and whether foundation vent replacement is needed. Full attic restoration with new insulation ranges from $3,200 to $4,500 for standard joist-bay blown-in fiberglass, and can reach $5,500 to $7,000 if spray foam air sealing or higher R-values are specified.
Several factors move these numbers. Attic accessibility matters: a hatch in a closet versus a pull-down stair changes crew efficiency. Contamination depth affects disposal volume and sanitizing time. Roof pitch and height determine how safely we can work at eave edges for exclusion. And the condition of existing air sealing, if any, determines how much prep work precedes insulation replacement.
