GreenFiber Attic Cleaning & Rodent Proofing in Boerne: What to Know First
We provide independent GreenFiber attic cleaning and rodent proofing in Boerne, typically completing most jobs in one to two days with a written price before any work starts. Most GreenFiber attic cleanouts with rodent exclusion run between $1,800 and $4,200 depending on contamination level and access complexity.

This page is for Boerne homeowners who installed GreenFiber cellulose insulation, or bought a home with it already in place, and now face rodent damage, soiled insulation, or compromised thermal performance. We’re an independent GreenFiber service provider, not affiliated with or authorized by the manufacturer. Our crews work across the Hill Country, including the older homes near the Cibolo Nature Center where stack-effect air leakage was eating through cooling bills before a single batt ever went in.
How GreenFiber Products Fail - and How We Fix Them
- Low Dust cellulose compression from rodent tunneling. GreenFiber’s Low Dust series is treated with borates for fire resistance, but that same chemistry makes it brittle once rodents have compacted it into runways. We remove the compressed material entirely, it cannot be fluffed back to original R-value, and replace it with fresh cellulose after sealing entry points.
- All Borate loose-fill saturation from roof leaks in Boerne’s spring storm cycles. The borate treatment leaches out when wet, leaving gray clumps that read as R-3 or R-4 per inch instead of the rated R-3.7. We see this most in homes off Balcones Creek where wind-driven rain finds lifted shingles. The fix is full removal, deck inspection, and reinstall after the roof is sound.
- Insulated Siding product misapplication in attic knee walls. Some Boerne contractors used GreenFiber’s Insulated Siding product in attic spaces where it was never specified, creating a vapor-permeable sandwich that traps Hill Country humidity against sheathing. We remove it, install proper kraft-faced batts or dense-pack cellulose, and detail the air barrier at the top plate.
- Stabilized cellulose settling around can lights and chase openings. GreenFiber’s stabilized formula resists settling better than standard cellulose, but it still migrates away from thermal bypasses over years of attic traffic and vibration. We rake it back, seal the penetrations with fire-rated foam and metal, then redistribute or supplement as needed.
- Rodent urine crystallization on borate-treated fibers. The alkaline borates react with uric acid over time, creating a hardened crust that standard vacuum equipment won’t lift. We use HEPA-filtered commercial extraction with agitation brushes, then apply enzyme treatment before any new insulation goes in. This is a GreenFiber-specific protocol, generic attic cleaners often miss the chemistry.
Our GreenFiber Attic Cleaning & Rodent Proofing Process

- 1
Call and schedule. A live person answers, 24/7. We book a site visit, not a sales pitch.
- 2
On-site assessment with photo documentation. We inspect the GreenFiber installation, identify the series, map rodent pathways, and test for active entry points. You get a written price before any work starts, Haven Standard Clause 1.
- 3
Removal and containment. Contaminated GreenFiber comes out under negative air pressure. We bag it, we don’t blow it around your soffits.
- 4
Structural repair and air sealing. Entry points get 1/4-inch hardware cloth or copper mesh where rodents gnaw, plus foam or metal flashing at penetrations. Top plates and can lights are sealed before any new insulation.
- 5
Sanitizing and deodorizing. Enzyme treatment on substrate, then a documented photo record of the clean deck.
- 6
Reinstall and verify. New GreenFiber or alternative product per your choice, with before-and-after blower-door numbers if air sealing was part of the scope. Seal the envelope first. Then fill it.
What GreenFiber Attic Cleaning & Rodent Proofing Costs in Boerne
| Scenario | Typical Range |
|---|---|
| Light cleanout, no rodent damage, re-fluff existing GreenFiber | $1,200 - $1,800 |
| Moderate contamination, partial removal, spot rodent exclusion | $2,400 - $3,600 |
| Full removal, heavy rodent damage, deck repair, complete reinstallation | $3,800 - $5,500 |
| Addition of air sealing and blower-door verification | Add $800 - $1,400 |
What moves the price: square footage, depth of existing insulation, extent of rodent contamination (guano requires PPE and disposal protocols), accessibility (cape cod kneewalls versus open attic), and whether the roof deck needs repair before new material goes in. We also service Reflectix radiant barrier systems if your attic has mixed materials.

Wes Okafor keeps a well-used copy of the ACCA Manual J on his truck and has been known to pull it out at a kitchen table when a homeowner wants to understand why R-38 in an attic floor matters differently than R-38 in a cathedral ceiling.

FAQs
No, GreenFiber’s warranty covers product defect, not installation or subsequent service work. As an independent GreenFiber service provider, we document our process with photos so any future claim can show the product was handled per specification. Call (830) 529-7780 if you need help interpreting your original warranty language.
We can source fresh GreenFiber cellulose through standard distribution channels, though we don’t represent ourselves as an authorized dealer. We also install Johns Manville, Knauf, and other borate-treated cellulose products that match GreenFiber’s performance specs. The choice is yours, and we quote both.
If the GreenFiber is compressed below 50% of original depth, contaminated with rodent waste, or has been wet and dried more than once, removal and replacement is the only code-compliant path. We test a sample area during our free estimate and show you the photo evidence. Call (830) 529-7780 to schedule.
Most jobs are scheduled within 3-5 business days and completed in one to two working days. Emergency situations, active rodent infestations with interior access, can sometimes be prioritized. A live person answers calls 24/7 to check availability.
We don’t price-match, we provide a free second opinion on any written estimate. Bring us a competing quote and we’ll read it with you, line by line, to compare scope, materials, and what’s actually included. Often the lower number omits air sealing, disposal, or proper PPE protocols.
