GreenFiber Insulation Removal & Replacement in Schertz: What to Know First
We provide independent GreenFiber insulation removal and replacement in Schertz, typically completing attic jobs in one to two days with same-day assessments available. Most GreenFiber removal and replacement jobs in a home this size run between $2,800 and $5,400 depending on contamination level, attic accessibility, and whether air sealing is required before new material goes in. We do not start work without a written price and a documented scope, and we do not blow new insulation over an unsealed attic floor.
This page is for Schertz homeowners who have GreenFiber cellulose insulation in their attic and are dealing with settling below labeled R-value, moisture damage, rodent contamination, or pre-2010 material that may contain fire-retardant chemicals now degrading into acidic dust. If you’re seeing uneven temperatures between rooms, musty attic air entering the living space, or your energy bills climbing despite the insulation you paid for, the insulation likely needs to come out before anything new goes in.

How GreenFiber Products Fail - and How We Fix Them
- GreenFiber All-Borate Cellulose settling below R-38 in 2×6 rafter cavities. Blown cellulose settles 15-20% from installed depth; in Schertz’s cooling-dominated climate, that gap translates to ceiling hot spots by July when attic temperatures in the Sedona subdivision off FM 1518 push past 140°F. We remove the settled material, air-seal the top plates and penetrations, then reinstall to a depth that accounts for settlement, with a post-install depth-stick photo log.
- GreenFiber Sanctuary insulation absorbing roof-deck moisture after bathroom vent failures. Cellulose wicks water laterally; a single disconnected flex duct can saturate a 6-foot radius before the homeowner smells it. We remove the contaminated batts or loose fill, treat the deck with an antimicrobial if fungal growth is present, repair the vent termination, and replace with new material only after moisture readings drop below 15%.
- Pre-2010 GreenFiber fire-retardant breakdown producing acidic dust. Older borate-ammonium sulfate blends degrade over time in high-heat attics, creating a fine, corrosive dust that migrates through can-light gaps into living spaces. We see this in Schertz homes built during the 2005-2008 boom. Full removal with HEPA containment is non-negotiable; we wear respirators, and so should anyone entering the attic before we arrive.
- GreenFiber loose fill compressed by storage boards or HVAC maintenance traffic. Compressed cellulose loses up to 50% of its R-value; we’ve pulled boards off 8-inch installs flattened to 3 inches. We remove the damaged material, reinforce the joist bays if storage is still needed, and reinstall with proper depth markers visible for future trades.
- Rodent nesting in GreenFiber creating biohazardous contamination. Cellulose is attractive nesting material; roof rat activity in Schertz’s established neighborhoods peaks in late fall. We remove all contaminated insulation with sealed-bag disposal, sanitize the attic deck, install rodent-proofing at entry points, then replace with new GreenFiber or an alternative if the homeowner prefers.
Our GreenFiber Insulation Removal & Replacement Process
- 1
Call and scheduling. A live person answers; we book an attic inspection, usually within 24-48 hours. You receive a text when the technician is en route.
- 2
Attic inspection and blower-door test. We pressurize the house to measure envelope leakage in CFM50 - a single number showing how much conditioned air escapes. In Schertz, we commonly see 3,500-5,500 CFM50 in homes with older GreenFiber and no prior air sealing. We photograph the existing insulation condition, depth, and any contamination or moisture.
- 3
Written price and scope. Before any work starts, you get a flat price, a written scope, and the 365-Day Done Right Promise in writing. Haven Standard Clause 1: no surprises.
- 4
Removal and containment. We set up HEPA-filtered negative air pressure, remove the GreenFiber in sealed bags, and dispose per Texas environmental guidelines. Contaminated jobs get antimicrobial treatment of the attic deck.
- 5
Air sealing and prep. Top plates, wire penetrations, can lights, and chimney chases get sealed with fire-rated foam or caulk. This happens before any new insulation touches the attic. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it.
- 6
Replacement, documentation, and verification. New insulation installed to labeled depth with depth-stick photos. On applicable jobs, a second blower-door test shows the improvement. You leave with a printed thermal-imaging summary, photo log, and written warranty.
What GreenFiber Insulation Removal & Replacement Costs in Schertz
These are real ranges for jobs we’ve completed in the Schertz corridor, including the Selma and Cibolo edges of our service area. Every job gets a flat written price before work starts.
| Scenario | Typical Range | What Moves the Price |
|---|---|---|
| Standard GreenFiber removal + replacement, 1,200 sq ft attic, no contamination | $2,800 - $3,800 | Attic height, joist spacing, need for baffles |
| Contaminated removal (rodent, moisture) + sanitizing + replacement | $3,800 - $5,400 | Extent of contamination, deck repairs, rodent-proofing scope |
| Pre-2010 fire-retardant degradation removal + full air sealing + replacement | $4,200 - $6,200 | Accessibility, number of can lights, chimney chase complexity |
| Partial removal (localized damage) + patch replacement | $1,400 - $2,400 | Area size, matching existing density if not full replacement |
Factors that increase cost: steep roof pitches above 8/12 requiring deck walking boards, attics with less than 30 inches of clearance at the ridge, and homes needing extensive top-plate sealing before new insulation can perform. We also service Reflectix radiant barrier systems if your attic has a hybrid installation requiring coordinated work.

Why Schertz Homeowners Call Topside Attic Insulation Schertz for GreenFiber Work
Wes Okafor and our crew have been working attics in Schertz long enough to know which subdivisions have the 2006-era GreenFiber installs now hitting their degradation window, and which have the newer All-Borate formulations holding up better in our heat. We’re an independent GreenFiber service provider - not affiliated with or authorized by the manufacturer - which means we source materials from GreenFiber, Owens Corning, Johns Manville, Knauf, Rockwool, and others based on what fits your home’s needs, not a proprietary lock-in.
Every job gets the Haven Standard: written price first, documented photo record last, and before-and-after blower-door numbers when air sealing is part of the scope. Our 365-Day Done Right Promise means if the insulation settles below spec or a sealed penetration fails, we return and make it right. Calls are answered by a live person 24/7, and our technicians are background-checked, uniformed, and trained in GreenFiber-specific handling protocols.
FAQs
GreenFiber’s limited warranty applies to original installation performed by authorized applicators; as an independent service provider, our 365-Day Done Right Promise covers our removal and replacement workmanship, not the original product warranty. If you’re concerned about warranty status, we review your documentation during the free estimate and explain what’s covered by our scope versus what isn’t.
Call (830) 402-5240 and we’ll walk through your paperwork with you.
Partial replacement can match density within 10% if the existing GreenFiber is in good condition and we know the original install specs; we test a sample bay during inspection to verify. If the existing material is too degraded or contaminated for reliable matching, we typically recommend full removal and replacement so the attic performs uniformly.
Call (830) 402-5240 for an assessment - estimates are free.
Most standard jobs are scheduled within 3-5 business days of estimate approval; contaminated or large-scale removals may require 7-10 days to coordinate disposal and material delivery. Emergency situations - active roof leaks saturating insulation, for example - get priority scheduling.

Adding over old GreenFiber is cheaper upfront by $800-$1,500, but we rarely recommend it. Settled or contaminated base layers reduce the new insulation’s effective R-value, trap moisture, and void any meaningful performance guarantee. In Schertz’s climate, the payback on proper removal, air sealing, and replacement typically shows in 3-5 years of cooling savings.
We’ll run the numbers both ways during your free estimate so you can decide with the full picture.
You get a printed or emailed packet: before-and-after photos, depth-stick photo log, blower-door test results if air sealing was performed, written scope completion checklist, and your 365-Day Done Right Promise warranty. No receipt-only jobs. Haven Standard: you leave with documentation, not just a bill.
