Attic Cleaning & Rodent Proofing in Seguin - Same-Day Service, Done Right the First Time

Trusted Attic Cleaning & Rodent Proofing for Seguin Homeowners

Attic Cleaning & Rodent Proofing - Seguin typically costs between $1,200 and $3,800 depending on contamination level and attic size, and most jobs are completed in one to two days. If you’re hearing scratching above the ceiling, noticing a musty smell, or finding droppings in the attic, you’re dealing with a problem that gets more expensive the longer it waits. We’ve been serving Seguin homeowners since 2016, and our crews are background-checked, uniformed, and trained to handle everything from light cleanouts to full attic restoration after a rodent infestation.

Seguin’s climate doesn’t help. Hot, humid summers and mild winters mean attics here stay warm enough for rodents to breed year-round, and the combination of older homes in the historic district near Court Street plus newer construction in the Mill Creek and Copper Ridge areas creates two very different attic environments we see regularly. In the older homes, we often find original insulation compacted with decades of rodent activity; in newer builds, we see gaps around plumbing and electrical penetrations that builders missed, creating entry highways before the first homeowner moves in. Either way, we start with a written price before any work starts, documented with photos, and we don’t leave until the attic is clean, sanitized, and sealed against future intrusion.

What Our Attic Cleaning & Rodent Proofing Service Includes

Attic Cleanout

An attic cleanout is the removal of all contaminated insulation, debris, and rodent nesting material down to the ceiling deck. You’ll need this when droppings, urine-soaked insulation, or shredded nesting material have compromised the space to the point where new insulation cannot be installed safely on top. In Seguin, we regularly see this condition in homes near the Guadalupe River where roof rats have established travel routes, and in attics where homeowners stored cardboard boxes that became nesting material. Our crew removes everything using HEPA-filtered vacuums and proper PPE, bags it for safe disposal, and documents the empty attic with photos before any restoration work begins. You receive that photo record as part of your job file.

Attic Sanitizing & Decontamination

Attic sanitizing and decontamination is the application of hospital-grade enzymatic cleaners and disinfectants to eliminate rodent-borne pathogens, neutralize urine odor, and break down organic contamination left after the physical cleanout. You need this step because rodent urine and feces can carry hantavirus, leptospirosis, and salmonella, and simply removing the visible material doesn’t address what soaked into the wood. In Seguin’s humidity, we’ve found that untreated contamination leads to persistent odor problems that penetrate ceiling drywall and affect indoor air quality. Our process includes a full-surface treatment of the attic deck, top plates, and accessible framing, followed by a second application in heavily affected areas. We use products rated for biohazard remediation, not consumer-grade sprays, and we document the treated surfaces with before-and-after photos.

Rodent Proofing & Exclusion

Rodent proofing and exclusion is the systematic sealing of all entry points larger than one-quarter inch, the installation of physical barriers at common breach points, and the creation of a complete perimeter defense. This is the critical step that separates a temporary fix from a permanent solution; without it, new rodents simply replace the ones removed. In Seguin, our inspection protocol focuses on roof-to-wall intersections, gable vent screens, plumbing and electrical penetrations, and the gap between the fascia and roof decking where squirrels and roof rats commonly enter. We use galvanized steel mesh, concrete patching compound, and specialized exclusion hardware that withstands chewing and weather exposure. Every sealed point is photographed and noted in your written scope. Under our 365-Day Done Right Promise, if rodents re-enter through any area we sealed, we return and make it right.

Attic Restoration

Attic restoration is the complete rebuild of the attic environment after cleanout and sanitizing, including the installation of new insulation to the appropriate R-value for Seguin’s climate zone, baffles for proper ventilation, and any necessary air sealing of the attic floor. You’ll need this when the original insulation was removed due to contamination, or when it was inadequate to begin with. We never blow new insulation over an unsealed attic floor; our protocol requires air sealing of top plates, can lights, and penetrations first, using blower-door guidance to verify the seal. For Seguin homes, we typically install blown-in fiberglass from Owens Corning or mineral wool from Rockwool to R-38 or R-49 depending on the structure and your energy goals. The job closes with a Documented Photo Record of the completed work, and on applicable jobs, before-and-after blower-door numbers showing the actual air-leakage reduction you paid for.

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 loose-fill products. In Seguin attics where we’re restoring after rodent damage, we often specify Owens Corning because their formaldehyde-free formulation holds up well in our humidity, and we can match existing insulation profiles when we’re doing partial restoration rather than full removal.

We also install Icynene open-cell spray foam for air sealing and insulation in complex attic geometries, and GreenFiber cellulose for homeowners who prefer a recycled-content option. Our crews are trained in the handling requirements for each material, and we source from Johns Manville, Knauf, and CertainTeed as well when the job specification calls for it. Whether your existing attic contains Owens Corning, Icynene, GreenFiber, or any other make, we can assess its condition, remove it if contaminated, and restore with the right product for your home’s envelope and your budget.

Signs You Need Attic Cleaning & Rodent Proofing Right Now

• Nocturnal scratching or scurrying sounds above the ceiling. Rodents are primarily active at night, and the sound of claws on drywall or movement through insulation is often the first sign homeowners notice. In Seguin’s established neighborhoods like Kingsbury and McQueeney, we’ve found that roof rats can travel tree-to-roof without ever touching the ground, making attic infestation possible even in well-maintained homes.
• Visible droppings or urine stains in the attic or around ceiling fixtures. Rodent droppings are dark, pellet-shaped, and typically concentrated near nesting sites or along travel paths. Finding them means active or recent infestation, and the associated pathogens require professional remediation rather than DIY cleanup, especially in enclosed attic spaces where disturbance can aerosolize contaminants.
• Unexplained musty or ammonia-like odors, especially in summer. The combination of Seguin’s heat and humidity accelerates the decomposition of rodent waste, producing odors that penetrate ceiling drywall and HVAC systems. If you smell something persistent that doesn’t resolve with standard cleaning, the source may be above the ceiling.
• Insulation that appears disturbed, compressed, or stained. Rodents tunnel through insulation to create nests, compressing it and reducing its R-value; urine staining is often visible as yellowed or darkened patches. In attics we’ve inspected near Seguin High School and throughout the Guadalupe County area, we’ve measured insulation that performed at less than half its rated value due to rodent damage and compaction.
• Chewed wiring, ductwork, or structural wood. Rodents gnaw continuously to keep their incisors trimmed, and attic wiring is a common target. This creates genuine fire risk, and we’ve documented cases in Seguin where exposed conductors were found during our initial inspection. Any sign of chewing warrants immediate professional assessment.

Our Attic Cleaning & Rodent Proofing Process - Step by Step

1. 1
   On-site inspection and written scope. We arrive on schedule, introduce the named technician who will lead your job, and conduct a full attic inspection including entry point identification, contamination mapping, and insulation condition assessment. We photograph everything and provide a written price before any work starts, with the scope, timeline, and warranty documented under Haven Standard Clause 1.
2. 2
   Physical cleanout and safe disposal. Our crew sets up containment to prevent cross-contamination, removes all compromised insulation and debris using HEPA-filtered extraction equipment, and bags everything for disposal according to Texas environmental regulations. The attic is swept to the deck, and you receive photos of the emptied space.
3. 3
   Sanitizing and decontamination. We apply professional-grade enzymatic treatment to all affected surfaces, allowing proper dwell time for the chemistry to work before any restoration begins. In Seguin’s humid climate, we pay particular attention to the attic deck and top plates where moisture can trap residual contamination.
4. 4
   Rodent proofing and exclusion. Using the entry point map from our inspection, we seal every breach with materials rated for rodent exclusion: galvanized steel mesh, concrete patch, and specialized hardware at vents and roof intersections. We verify the seal with a final walkthrough and document each repair with photos.
5. 5
   Restoration and final documentation. We air seal the attic floor, install baffles for ventilation, and place new insulation to the specified R-value. The job closes with a Documented Photo Record, your written warranty under the 365-Day Done Right Promise, and on applicable jobs, before-and-after blower-door readings showing the actual performance change.
