GreenFiber Attic Cleaning & Rodent Proofing in Schertz: What to Know First
We provide independent GreenFiber attic cleaning and rodent proofing in Schertz, with most jobs completed in one to two days and a written price delivered before any work starts. As an independent GreenFiber service provider, we are not affiliated with or authorized by GreenFiber, but we stock the correct removal equipment and replacement materials for their cellulose blow-in lines. Typical turnaround from inspection to completion runs 48 to 72 hours for standard cleanouts, with same-day emergency response when rodent activity has compromised living-space air quality. This page is for Schertz homeowners who found GreenFiber cellulose in their attic and need it removed, sanitized, and replaced after rodents, moisture, or simple age have degraded it. Call (830) 402-5240 for a free estimate with a written scope.
How GreenFiber Products Fail - and How We Fix Them
- Low Dust and SAN cellulose settling below labeled depth. GreenFiber’s Low Dust and SAN-treated lines compress 15 to 25 percent in Schertz’s heat-cycling attics within five to seven years, creating thermal bypasses where R-value was promised. We remove the settled material, air-seal the top plates and penetrations that the original installer likely skipped, then reinstall to a verified depth with depth-stick documentation.
- Fire-retardant borate washout in humid edge zones. GreenFiber relies on borate treatment for fire resistance, but in Schertz homes near Cibolo Creek or with ridge-vent gaps that pull Gulf moisture, borate leaches toward the attic perimeter and loses effectiveness. We test retained borate levels during inspection; if washout is present, we remove the compromised material rather than leave a fire-code liability in place.
- Rodent nesting in loose-fill cellulose. GreenFiber’s loose-fill consistency is ideal tunneling material for roof rats and mice, especially in older Schertz subdivisions like Sedona where mature oak canopies give roof access. We extract all contaminated cellulose, HEPA-vacuum the substrate, apply enzymatic decontamination, then install rodent-proofing barriers at soffit junctions and pipe penetrations before any new insulation goes in.
- Moisture absorption and compression in unvented or poorly vented attics. GreenFiber cellulose holds moisture at 15 to 20 percent higher rates than fiberglass in Schertz’s spring humidity spikes; once compressed, it dries poorly and supports mold. We identify the ventilation failure, remove the wet pack, remediate framing if needed, and correct intake-exhaust balance before reinstalling.
- Insulator blower inconsistency creating density voids. GreenFiber’s recommended install density is 1.6 to 2.0 pounds per cubic foot, but DIY and discount jobs in Schertz often run light, leaving pockets where rodents travel and heat escapes. We use commercial-grade blowers with inline density meters, and we photograph the depth stick every four feet so the homeowner has a record, not a guess.
Our GreenFiber Attic Cleaning & Rodent Proofing Process

- 1
Inspection and blower-door baseline. We pressurize the house to measure envelope leakage, then thermal-image the attic to locate compressed or missing GreenFiber, moisture staining, and rodent trails. You get the CFM50 number in writing.
- 2
Written scope and price. Under Haven Standard Clause 1, we deliver a flat price, written scope, and written warranty before anyone lifts a tool. No work starts without it.
- 3
GreenFiber removal and HEPA extraction. We bag all compromised cellulose, vacuum the deck with HEPA filtration, and dispose per Texas environmental handling guidelines for borate-treated material.
- 4
Air sealing and rodent exclusion. Top plates, can lights, plumbing chases, and soffit junctions get sealed with fire-rated caulk and metal flashing; rodent barriers go in at all penetration points. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it.
- 5
Sanitizing and substrate treatment. Enzymatic decontamination for rodent waste, borate reapplication to framing if indicated, and moisture-content verification with pin meters.
- 6
Reinstall, test, and document. New GreenFiber or alternative material to verified depth, post-job blower-door test, thermal-imaging summary, and depth-stick photo log delivered before we leave.
What GreenFiber Attic Cleaning & Rodent Proofing Costs in Schertz
| Scenario | Typical Range | What Moves the Price |
|---|---|---|
| Partial cleanout, no rodent damage, reusing accessible GreenFiber | $1,800 - $2,800 | Attic square footage, accessibility, whether original install included air sealing |
| Full removal and replacement, moderate rodent soiling | $3,200 - $4,800 | Volume of contaminated material, extent of decontamination required, soffit repair for exclusion |
| Full restoration with structural remediation, heavy rodent damage | $5,500 - $8,500 | Framing replacement, electrical rerouting, extensive air sealing, multiple return trips |
| Rodent proofing and exclusion only (no insulation work) | $900 - $1,600 | Linear feet of soffit to seal, number of penetration points, roofline complexity |
Most Schertz homes in the 1,800 to 2,400 square-foot range with original GreenFiber installs from the 2015 to 2020 construction wave fall in the $3,200 to $4,800 band. Price moves up with attic temperature damage from our 140°F summer peaks, down if the original installer did proper air sealing that we can verify.

Why Schertz Homeowners Call Topside Attic Insulation Schertz for GreenFiber Work

We’ve been working the Schertz corridor for several years now, including jobs in the Sedona subdivision off FM 1518 where summer attic temps regularly push past 140°F before a single batt goes in. Our 365-Day Done Right Promise applies to every completed job, and we publish before-and-after blower-door numbers so you can verify the air-sealing result yourself. Our technicians are background-checked and uniformed, and calls are answered by a live person 24/7 - no voicemail loops. We also service Reflectix radiant barrier systems, so multi-material attics get coherent treatment rather than patchwork. Every job closes with a Documented Photo Record, not just a receipt.
FAQs
GreenFiber’s limited warranty covers original install defects, not subsequent service work, so professional removal and reinstallation by an independent provider does not inherently void coverage. We document our process with photos and depth readings so any future warranty claim has clear evidence of proper handling. Call (830) 402-5240 if you need help interpreting your original warranty documents.
We source GreenFiber cellulose through standard distribution channels and can match the original product line when specified; we also install quality aftermarket cellulose from Johns Manville, Knauf, and Owens Corning when the homeowner prefers. We do not claim exclusive or preferred status with any brand, and we explain the density and fire-rating equivalencies in writing before you choose.
Spot repair is cheaper only when contamination is localized and the remaining material tests clean for borate retention and moisture content. In Schertz’s climate, we find that partial repairs often fail within two years because rodents return to familiar scent trails or because uncompacted edge zones create new thermal bypasses. We give honest repair-versus-replace guidance based on inspection data, not a default upsell.
Most jobs run one to two days from start to finish; emergency response for active rodent contamination or severe odor issues is typically same-day or next-day. We do not manufacture urgency or claim limited slots - we schedule based on crew availability and job complexity, with a named technician and a text when they are on the way. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
You get a written scope completion checklist, before-and-after blower-door readings on applicable jobs, a printed thermal-imaging summary, a post-install depth-stick photo log, and the written 365-Day Done Right Promise. This is standard on every visit, not available on request - we believe you should know what leaving looks like before we arrive.
