GreenFiber Attic Cleaning & Rodent Proofing in New Braunfels: What to Know First
We provide independent GreenFiber attic cleaning and rodent proofing in New Braunfels, with most jobs completed in one to two days and a written price delivered before any work starts. As an independent GreenFiber service provider - not affiliated with or authorized by the manufacturer - we service the full GreenFiber product line including All Borate loose-fill, Sanctuary blow-in, and stabilized cellulose systems found in homes across Comal and Guadalupe counties. Most attic cleanouts with full decontamination and rodent exclusion run between $2,400 and $4,800 depending on contamination level and attic square footage. Call (830) 243-6352 for a free estimate with a written scope; we also review any competing quote at no charge.
How GreenFiber Products Fail - and How We Fix Them
- All Borate loose-fill compresses after rodent nesting activity. GreenFiber’s All Borate line relies on lofted cellulose fiber to achieve its stated R-value; once rodents tunnel through and compact it, the insulation settles below the joist line and thermal performance drops by 30% or more. We remove the contaminated material entirely, sanitize the deck, then reinstall to original depth with fresh product.
- Sanctuary stabilized cellulose wicks moisture from rodent urine. The boric acid treatment in Sanctuary acts as a fire retardant and mold inhibitor, but it does not prevent cellulose from absorbing liquid waste. In New Braunfels homes near the Guadalupe River corridor, we’ve found Sanctuary saturated enough to register above 20% moisture content on a pin meter - that fiber stays out, period.
- GreenFiber’s low-dust formula masks active infestation longer than fiberglass. Because the cellulose binds dust, homeowners often don’t smell or see rodent activity until population pressure forces rats into living spaces. We use UV light scanning to locate urine trails even when the material looks clean, then map entry points with a borescope before touching anything.
- Stabilized products bridge across recessed can lights, creating bypasses. GreenFiber’s adhesive-treated stabilized line can form a crust over non-IC-rated fixtures; rodents exploit these gaps as travel corridors. We pull back all material near electrical penetrations, seal with fire-rated foam and metal flashing, then reinstall - never blow new fiber over unsealed hazards.
- Cellulose around HVAC flex duct attracts roof rats for nesting material. The shredded paper texture is ideal for rat den construction, especially in New Braunfels attics that hit 140°F in July and 30°F in January. We install galvanized hardware cloth barriers at duct penetrations and replace any flex with damage - not tape, not patch, replacement.
Our GreenFiber Attic Cleaning & Rodent Proofing Process
- 1
Written price and scope before arrival. Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. You’ll know exactly what the job includes and what it costs.
- 2
Blower-door test and attic inspection. We pressurize the house to measure CFM50 baseline, then inspect with borescope and UV light to locate contamination, entry points, and air leaks. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
- 3
Contaminated GreenFiber removal and HEPA extraction. All compromised material comes out through sealed chutes; nothing drops into living spaces. We document with photos at this stage.
- 4
Sanitizing, decontamination, and structural repair. Enzyme treatment on decking, replacement of chewed wiring or flex duct, and metal flashing at all penetration points. OEM GreenFiber replacement stock or quality aftermarket per your written scope.
- 5
Air sealing and rodent exclusion. Top plates, can lights, plumbing stacks, and eave gaps sealed before any new insulation goes in. Hardware cloth on vents, concrete patch on foundation gaps, one-way exits where active.
- 6
Reinstall, retest, and documented closeout. Fresh insulation to spec, post-job blower-door reading, photo record delivered. Pre- and post-job numbers printed for your file.

AfterWhat GreenFiber Attic Cleaning & Rodent Proofing Costs in New Braunfels
Most jobs in the New Braunfels area fall into these ranges based on what we find:
| Scenario | Typical Range |

What moves the price: attic square footage, depth of existing GreenFiber, extent of rodent contamination, whether HVAC flex duct needs replacement, and how many entry points require exclusion work. We also service Reflectix radiant barrier systems when those are present and damaged. Every estimate is free, written, and valid for 30 days.

FAQs
No - GreenFiber’s limited warranty covers product defect, not installation or maintenance by independent service providers. As an independent GreenFiber service provider, our work does not affect that product warranty, though damage from unqualified contractors might. We document our process with photos and written scope to protect you if questions arise. Call (830) 243-6352 and we’ll explain what’s covered.
Most jobs complete in one to two days; heavy contamination or large attics may run into a third day. We don’t rush the sanitizing phase - enzyme treatment needs dwell time to neutralize rodent-borne pathogens. You’ll get a written schedule with your price before we start.
Replace any cellulose that has been urinated on or heavily compacted; spot-cleaning leaves odor trails that attract new rodents and doesn’t restore R-value. We recommend full removal and reinstall when contamination exceeds roughly 20% of attic area - the crossover point where partial repair costs nearly as much and performs worse. We’ll show you the UV scan and let you decide.
We stock both OEM GreenFiber products and quality aftermarket cellulose from Knauf and Owens Corning. For warranty-sensitive jobs or color-matching existing stabilized product, we use OEM. For standard re-blow after cleanout, aftermarket often performs identically at lower cost - your written scope specifies which before we start.
We schedule inspections within 24-48 hours for active rodent issues, with same-day availability for severe contamination affecting indoor air quality. Emergency exclusion - sealing active entry points to stop ongoing intrusion - can often be done on the first visit while the full cleanout is scoped. Call (830) 243-6352; a live person answers 24/7.
