We’ve pulled insulation saturated with raccoon waste from attics in Startzville and sealed entry points in homes overlooking the lake where roof rats had chewed through soffit vents. Every job starts with a written price and ends with a Documented Photo Record showing what we found, what we removed, and what we sealed. Under The Haven Standard, we don’t perform attic cleaning over unsealed air leaks; if your attic floor needs sealing, we complete that work first so new insulation isn’t contaminated by the same airflow patterns that attracted pests.

What Our Attic Cleaning & Rodent Proofing Service Includes

Attic Cleanout

An attic cleanout is the complete removal of contaminated insulation, debris, and organic waste so the space can be properly sanitized and reconditioned. In Canyon Lake, we regularly find attics packed with decades of blown-in fiberglass mixed with rodent nesting material, especially in homes built during the 1980s lake-area expansion that never received proper air sealing. Our crew removes everything down to the deck, bags it for proper disposal, and hauls it away so you’re not left with a dumpster in your driveway.

We typically recommend a full cleanout when insulation has been compressed below R-30, when visible fecal matter covers more than 10% of the surface area, or when the homeowner reports persistent odors reaching the living space through recessed can lights. After cleanout, we photograph the bare attic deck and share these images with you before any restoration work begins.

Attic Sanitizing & Decontamination

Attic sanitizing applies EPA-registered disinfectants and enzymatic treatments to neutralize pathogens left by rodents, bats, or raccoons, including hantavirus, leptospirosis, and histoplasmosis spores that can become airborne during disturbance. In Canyon Lake’s humid subtropical climate, microbial growth accelerates in attics with poor ventilation, particularly in lake-adjacent neighborhoods where morning fog traps moisture against roof decks until mid-morning. We treat all exposed framing, decking, and ductwork with commercial-grade sanitizer, then apply a deodorizing encapsulant where heavy contamination existed.

This step is non-negotiable after rodent activity; vacuuming alone doesn’t deactivate the proteins in urine that trigger allergic responses or the bacteria in droppings that become airborne when new insulation is disturbed. We document sanitizing coverage with photos and note any structural damage requiring repair before insulation replacement.

Rodent Proofing & Exclusion

Rodent proofing, also called exclusion, is the systematic sealing of every entry point larger than 1/4 inch - the width a juvenile roof rat needs to access your attic. In Canyon Lake, the most common entry routes we find are gaps where stucco meets roof fascia, unscreened gable vents, plumbing stack penetrations, and the corners where ridge vents terminate. We seal with galvanized steel mesh, copper wool, and professional-grade sealants that rodents can’t chew through, unlike the spray foam homeowners often try first.

Our exclusion work includes a perimeter inspection of the roofline, soffits, foundation, and any attached structures like boat docks or lake-facing pergolas that create roof access. We provide a written map of every entry point found and sealed, with photos, so you know exactly what was addressed. Without thorough exclusion, new rodents will replace the old ones within weeks.

Attic Restoration

Attic restoration returns the space to a clean, thermally functional condition after contamination or damage, combining new insulation with the air sealing that should have preceded the original installation. In Canyon Lake homes, we frequently discover top plates, wire penetrations, and chimney chases that were never sealed during construction, creating both energy loss and scent highways that guide rodents to living spaces below. We air seal every penetration with fire-rated caulk and foam, then install new insulation to the appropriate R-value for our climate zone.

Restoration includes replacing damaged baffles, repairing ductwork where rodents have chewed flex lines, and installing proper vent chutes where soffit intake was blocked by old insulation. On every restoration job, 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 publish the before-and-after results so you can verify the performance change.

Brands We Service for Attic Cleaning & Rodent Proofing

We’ve worked extensively with Owens Corning insulation systems, including their AttiCat blown-in fiberglass and ProPink Loosefill products commonly found in Canyon Lake homes from the 1990s forward. When we encounter Owens Corning insulation contaminated by rodents, we know its density characteristics and can accurately estimate removal time and replacement volume, which keeps our written prices accurate rather than inflated with guesswork.

Johns Manville blown-in fiberglass and mineral wool are also frequent finds in local attics, particularly in custom homes where builders specified higher-density products for sound control between living levels. Our crews are trained in the handling requirements for both JM’s fiberglass and their Spider custom-blown system, which requires specific equipment settings we maintain on our trucks.

We’ve also removed and replaced Knauf EcoFill and Jet Stream products, as well as GreenFiber cellulose - the latter especially common in energy-efficient builds from the late 2000s where builders prioritized recycled content. Whether your attic contains Owens Corning, Johns Manville, Knauf, GreenFiber, or any other make, we can assess its condition, remove it safely, and specify appropriate replacement materials.

Signs You Need Attic Cleaning & Rodent Proofing Right Now

• Nocturnal scratching or scurrying sounds above ceiling drywall. Roof rats and squirrels are most active between 10 PM and 4 AM, and Canyon Lake’s mature oak canopy provides continuous aerial highways from tree branches to rooflines. If you’re hearing movement, the animals have already established scent trails that will attract others even after the current occupants are removed.
• Visible droppings or urine stains around recessed can lights or attic access hatches. Rodent waste contains pheromones that signal “safe harbor” to other animals, and the proteins in dried urine become airborne when disturbed by HVAC airflow. We find this most often in homes near the lake where roof rats travel along utility lines and drop into attics from overhanging branches.
• Insulation that appears flattened, tunneled, or discolored in patches. Healthy blown-in insulation maintains loft and uniform color; dark trails or compressed pathways indicate rodent traffic, while gray or black staining suggests urine saturation. In Canyon Lake’s heat, contaminated insulation becomes a source of odor that migrates downward through ceiling penetrations.
• Unexplained increases in cooling costs during summer months. Rodent-damaged insulation loses R-value, but more critically, the air leaks rodents create or enlarge allow conditioned air to escape while pulling attic heat and humidity into living spaces. We’ve measured attic floors in Canyon Lake homes where rodent activity had increased cooling load by 30% before the homeowner connected the symptoms.
• Dead animal odor that persists for more than 48 hours. A single decomposing rodent can foul 2,000 square feet of living space for two weeks in summer heat, and the carcass is rarely accessible without removing insulation. If you smell decay from above, there’s likely a larger population you’re not seeing, and the biological load in your attic requires professional remediation.

Our Attic Cleaning & Rodent Proofing Process - Step by Step

1. 1
   On-site assessment and written scope. We arrive at your Canyon Lake home with a named technician who texts when en route. They inspect the attic through the access hatch first, documenting contamination extent with photos, then walk the exterior perimeter to identify entry points. You’ll receive a flat written price with scope details before any work begins - Haven Standard Clause 1, no exceptions.
2. 2
   Containment and negative air setup. Before disturbing contaminated material, we seal the attic access and establish negative air pressure to prevent biological particles from migrating into living spaces. Our HEPA filtration captures particles down to 0.3 microns. We also cover floors and furniture below the work area with protective sheeting, particularly important in Canyon Lake homes with open-concept designs where attic access opens directly into hallways or closets.
3. 3
   Complete removal and disposal. We remove all contaminated insulation, debris, and organic material using commercial vacuums with HEPA filtration, bagging waste for proper disposal per Texas environmental regulations. For heavy contamination, we remove material in controlled sections to maintain containment. The attic deck is then scraped and vacuumed to bare wood or existing radiant barrier.
4. 4
   Sanitizing, deodorizing, and structural repair. We apply EPA-registered disinfectant to all surfaces, followed by enzymatic treatment that breaks down urine proteins and organic odors. Where rodents have chewed wiring, ductwork, or structural members, we document damage with photos and can coordinate licensed repair contractors. We then air seal all penetrations, top plates, and chases with fire-rated materials before any new insulation enters the space.
5. 5
   Exclusion sealing and final documentation. Every entry point 1/4 inch or larger is sealed with rodent-proof materials - steel mesh, copper wool, and professional sealants - and we photograph each location. We restore insulation to appropriate R-value, run a blower-door test on applicable jobs, and deliver your Documented Photo Record showing before, during, and after conditions. The 365-Day Done Right Promise covers all completed work.
