Trusted Attic Cleaning & Rodent Proofing for Leander Homeowners
Attic cleaning and rodent proofing in Leander typically costs $1,200-$3,800 depending on contamination level, attic square footage, and whether structural repairs are needed. Most jobs take one to three days, and we can often start within 48 hours of your call. Call (737) 252-7159 for a written estimate with no obligation.
We’ve been in Leander attics since 2016, and the pattern is consistent: homeowners smell something off in the hallway, find insulation scattered in odd places, or hear scratching above the bedroom ceiling at 3 a.m. By the time most people call, rodents have already compressed insulation trails through the fiberglass, left urine saturation in the bays above master bedrooms, and chewed wiring runs near the HVAC air handler. We’re Envelope Insulation Co., operating under The Haven Standard, and we don’t just trap and leave. We clean out the debris, sanitize the surfaces, seal every entry point larger than a quarter-inch, and restore the thermal boundary so your attic performs the way it was designed to. Every job starts with a written price and ends with a Documented Photo Record. On homes where air sealing is part of the scope, you’ll also get before-and-after blower-door numbers, a pressurization reading that shows, in one figure, how much conditioned air your home was losing before and after our crew finished.
What Our Attic Cleaning & Rodent Proofing Service Includes
Attic Cleanout
An attic cleanout is the removal of all contaminated insulation, rodent nesting material, droppings, and debris down to the drywall or plank ceiling below. You need this when your insulation has been tunneled through, compressed below its original R-value, or mixed with organic matter that can’t be separated. In Leander - Attic Cleaning & Rodent Proofing, we see this most often in homes built between 2005 and 2015 in neighborhoods like Crystal Falls and Travisso, where builder-grade blown-in fiberglass was installed with minimal air sealing and rodents found easy access through gable vents and roof-wall junctions. Our crew removes everything with HEPA-contained vacuums, bags it for proper disposal, and leaves the attic floor ready for inspection and treatment. You’ll receive photos of the empty attic deck before any next step begins.

Attic Sanitizing & Decontamination
Attic sanitizing and decontamination is the application of EPA-registered antimicrobial treatments to kill bacteria, neutralize odors, and break down organic contamination left by rodents or long-term moisture intrusion. You need this after any rodent activity, because hantavirus and leptospirosis don’t require live animals to present a risk, dried droppings become aerosolized when disturbed. In Leander’s climate, where summer attic temperatures exceed 140°F, urine proteins bond to wood and drywall more aggressively than in cooler markets. We apply a two-stage treatment: enzyme breakdown first, then antimicrobial fogging that penetrates into porous framing. The product we use is rated for residential occupied spaces and leaves no residual odor. We document application points in your photo record.

Rodent Proofing & Exclusion
Rodent proofing and exclusion is the physical sealing of all entry points, gaps, and construction flaws that allow mice, rats, squirrels, and raccoons to access your attic. You need this after removal and cleaning, because without it, you’re funding a recurring service, not solving a problem. Our crews in Leander find that roughly 60% of entries are within 18 inches of the roofline: torn soffit screens, gaps where dormers meet the main roof, and pipe penetrations through gable ends that were never sealed during original construction. We use galvanized steel mesh, concrete patching compound, and specialized sealants rated for expansion and UV exposure. Every sealed point is photographed and mapped to your home’s exterior so you know what was found and how it was fixed.

Attic Restoration
Attic restoration is the rebuilding of your thermal and air barriers after contamination has been removed and entry points sealed. You need this when your insulation is gone, damaged, or no longer performing to its labeled R-value. In Leander, code minimum for attic insulation is R-38, but many homes we restore in the Cedar Park-Leander corridor were originally built to R-30 or less and have since degraded through compression and moisture cycling. For homeowners looking for our Attic Cleaning & Rodent Proofing in Cedar Park, we apply the same restoration standards. We air seal first, then insulate, in that order, Envelope will never blow new material over an unsealed attic floor. Top plates, can lights, and penetrations are sealed before any insulation is added. We install Owens Corning blown-in fiberglass, GreenFiber cellulose, or Icynene open-cell spray foam depending on your roof configuration and budget. Every restoration job includes a written scope, a written warranty, and on applicable jobs, before-and-after blower-door readings so you can verify the performance change.

Brands We Service for Attic Cleaning & Rodent Proofing

We work with the insulation and air-sealing materials your home already has, or we specify new product from manufacturers we trust. Owens Corning blown-in fiberglass is what we install most often in Leander restorations, their AttiCat system lets us achieve consistent density and full coverage in truss bays with limited access. We’ve also used Icynene open-cell spray foam extensively in homes with conditioned attic assemblies or complex rooflines where batts and blown-in can’t seal effectively. For homeowners who prefer cellulose, GreenFiber provides a treated, recycled-content option that performs well in Leander’s mixed-humid climate when paired with proper air sealing and ventilation.
Whether your attic currently contains Owens Corning, Icynene, GreenFiber, Demilec, or any other manufacturer, we can assess its condition, remove it if contaminated, and specify replacement that matches your performance goals and budget. We carry no exclusive agreements, no proprietary product lock-in. Our material recommendations are based on what your specific roof deck, ventilation, and air-leakage profile require.
Before
AfterSigns You Need Attic Cleaning & Rodent Proofing Right Now
- Insulation displacement or trails. If your attic insulation looks like someone dragged a rake through it, that’s not settling. Rodents tunnel through fiberglass to create runways between nesting sites and food sources. Compressed insulation loses up to 50% of its R-value, and the displaced material often blocks soffit vents, creating moisture problems that compound the original damage.
- Urine odor or staining on ceiling drywall. That ammonia smell in your hallway or closet ceiling indicates active or recent rodent presence. In Leander’s hard-water areas, urine salts can also leave crystalline staining that bleeds through paint even after the animals are gone. The odor won’t dissipate without removal of contaminated material and enzyme treatment of the substrate.
- Scratching or movement sounds during quiet hours. Nocturnal scratching above bedrooms or in wall cavities typically means mice or rats. Squirrels are active dawn and dusk. Either way, the longer they remain, the more wiring they chew, the more insulation they destroy, and the more entry points they create for other pests. We’ve found chewed Romex in Leander homes that presented fire risks the homeowner never suspected.
- Droppings in attic corners, along beams, or near the hatch. Rodent droppings are the most definitive sign of activity. Fresh droppings are dark and moist; old ones are gray and crumbly. Both require HEPA vacuum removal and surface sanitizing. Never sweep or vacuum droppings with a standard household vacuum, the aerosolized particles are a documented hantavirus transmission pathway.
- Sudden increase in energy bills without HVAC changes. If your summer cooling costs in Leander jumped 20% or more and your AC unit checks out, compromised attic insulation is a likely culprit. Rodent tunnels create convection pathways that bypass your thermal barrier. Air leaks from chewed penetrations add direct infiltration load. We’ve measured blower-door reductions of 1,500 CFM50 or more after sealing rodent-created gaps in otherwise intact envelopes.
Our Attic Cleaning & Rodent Proofing Process - Step by Step

- 1
On-site inspection and written scope. We arrive on schedule, you get a named technician and a text when they are on the way. Under Haven Standard: Arrive on schedule. The technician inspects your attic access, documents contamination with photos, identifies entry points from both interior and exterior, and measures attic square footage and insulation depth. You receive a written price before any work starts, flat price, written scope, written warranty. No exceptions.
- 2
Containment and removal. We seal your living space from the work zone with plastic sheeting and negative-air setup where contamination is severe. All contaminated insulation, droppings, nesting material, and debris are HEPA-vacuumed and bagged for disposal at licensed facilities. The attic deck is swept to bare substrate. You receive photos of the cleaned space before any treatment begins.
- 3
Sanitizing and decontamination. We apply enzyme treatment to break down urine proteins and organic matter, followed by antimicrobial fogging that penetrates framing, sheathing, and masonry surfaces. The product is EPA-registered for residential use and requires a brief drying period before restoration work begins. Application points are documented in your photo record.
- 4
Exclusion and air sealing. Every entry point quarter-inch or larger is sealed with rodent-proof materials: galvanized steel mesh, concrete patch, specialized sealants. We also air seal top plates, can lights, pipe penetrations, and chimney chases, the same defects that let rodents in also let conditioned air out. On applicable jobs, we run a blower-door test before and after to quantify the improvement.
- 5
Restoration and final documentation. We install replacement insulation to the specified R-value, verify ventilation pathways are clear, and conduct a final walkthrough with you. You receive your Documented Photo Record, written warranty, and on air-sealing jobs, the before-and-after blower-door readings. The 365-Day Done Right Promise applies: if it’s not done right, we make it right.
How Much Does Attic Cleaning & Rodent Proofing Cost in Leander?
A typical Attic Cleaning & Rodent Proofing pricing for a cleanout and sanitizing in Leander runs $1,200-$2,400 for a 1,500-square-foot attic with moderate contamination. Full restoration including removal, decontamination, exclusion, and new insulation installation ranges $2,800-$3,800 for the same footprint. Smaller partial cleanouts with limited contamination may fall below $1,200; larger homes in Crystal Falls or Travisso with complex rooflines and severe damage can exceed $4,500.
Several factors move the price. Attic square footage is the largest driver, more space means more material to remove and replace. Contamination severity affects labor hours: light droppings versus saturated decking requiring replacement. Accessibility matters too, attics with limited hatch size, steep pitches, or buried HVAC equipment take longer to work in. The type of replacement insulation you choose also shifts cost: blown-in fiberglass from Owens Corning or GreenFiber cellulose typically runs less than Icynene or Demilec spray foam applications.

Attic Cleaning & Rodent Proofing in Georgetown and surrounding areas involves the complete removal of contaminated insulation and debris, sanitizing of affected surfaces, sealing of all animal entry points, and restoration of the attic’s thermal performance. It’s needed when rodents, squirrels, or other pests have compromised your insulation, created odor or health hazards, or damaged air-sealing details.
