GreenFiber Insulation Removal & Replacement in Boerne: What to Know First
We provide independent GreenFiber insulation removal and replacement in Boerne, typically completing attic jobs in one to two days with a written price delivered before any work starts. Most GreenFiber cellulose removals in this market run $2.40-$4.20 per square foot depending on contamination level and attic accessibility, with replacement pricing following a separate written scope. This page is for Boerne homeowners who found GreenFiber in their attic, suspect it’s compromised, and want to know what honest remediation looks like without a sales pitch. Call (830) 529-7780 - a live person answers, 24/7.
How GreenFiber Products Fail - and How We Fix Them
- GreenFiber Sanctuary settled below grade in attic floors. The loose-fill cellulose compresses over 8-12 years in Boerne’s heat-cycling climate, dropping from an installed R-38 to an effective R-22 or lower. We remove the compacted material, seal top plates and can-light penetrations, then reinstall to true depth with fresh cellulose or an alternative if the homeowner prefers.
- GreenFiber All Borate fire-retardant treatment leached out near roof leaks. The borate salts that give cellulose its Class 1 fire rating wash toward eaves when attics take on water, leaving pockets of untreated, grayed material. We spot-test with a boric acid reagent strip during removal, document the leach zones with photos, and only reinstall after the roof leak source is verified fixed.
- GreenFiber stabilized cellulose clumped from humidity in unvented Boerne attics. The acrylic binder meant to reduce dust during install turns gummy when relative humidity stays above 70% for extended periods, common in Hill Country shoulder seasons. We scrape and vacuum the clumps, then recommend adding ridge venting or switching to a non-stabilized product if the attic moisture source can’t be eliminated.
- GreenFiber subflooring installed over unsealed bypasses in pre-2000 Boerne homes. We see this near the Cibolo Nature Center area - cellulose blown over open chases around brick chimneys and plumbing stacks, creating a filter that traps humidity against framing. We remove the contaminated material, seal the bypasses with fire-rated foam and rigid baffles, then reinsulate. Seal the envelope first. Then fill it.
- GreenFiber contaminated by rodent activity in prolonged vacancy. Cellulose holds urine and organic matter more tenaciously than fiberglass, and the paper-based material supports fungal growth when soiled. We perform full removal with HEPA containment, treat the decking with an enzyme cleaner, and can rodent-proof before reinstalling - documented with photos at each stage.
Our GreenFiber Insulation Removal & Replacement Process
- 1
Site visit and written price. We inspect the attic access, measure square footage, test for asbestos if the home was built before 1990, and deliver a flat price with scope and warranty in writing - Haven Standard Clause 1. No work starts without it.
- 2
Blower-door baseline. On applicable jobs, we run a pressurization test - a reading that shows, in one number, how much conditioned air the building envelope is losing. This gives us a CFM50 figure before we disturb anything.
- 3
Containment and removal. We isolate the attic hatch with plastic sheeting, run negative air if contamination is present, and vacuum GreenFiber material with a high-capacity gas-powered collector. All debris is bagged and hauled.
- 4
Air sealing and substrate repair. Before any new insulation goes in, we seal top plates, wire penetrations, can lights, and chimney chases. We also replace degraded baffles and repair decking as needed.
- 5
Replacement and verification. We install the chosen replacement material to the specified R-value, then rerun the blower-door test. The homeowner receives printed pressure-differential reports in pascals, plus a Documented Photo Record of the sealed attic and installed insulation.
- 6
Written warranty and 365-Day Done Right Promise. The job closes with a written scope, warranty, and our promise: if it’s not done right, we make it right.

Boerne’s limestone substrate and older homes near the historic district often require longer hose runs and manual bagging, which adds labor but not surprises - it’s in the written price from day one.

Why Boerne Homeowners Call Topside Attic Insulation Boerne for GreenFiber Work
We’ve removed GreenFiber from attics across the Hill Country since 2016, and we’ve learned that cellulose jobs fail when the crew treats removal as demolition instead of diagnostics. Wes Okafor runs a blower-door test before and after every applicable job, then hands the homeowner a printed pressure-differential report so the numbers are on paper and not just a claim. Our technicians are background-checked and uniformed; calls are answered by a live person, 24/7. We also service Reflectix and other brands, so if your GreenFiber replacement makes sense as part of a multi-system upgrade, we can scope it together without bringing in another contractor. The 365-Day Done Right Promise applies to all completed work, and every job ends with a Documented Photo Record - included, not available on request.
FAQs
No - GreenFiber’s limited warranty applies to product defect, not to removal by an independent service provider. As an independent GreenFiber service provider, we document the original install condition with photos before removal, which actually protects you if a product defect claim ever arises. Call (830) 529-7780 if you want us to review your install documentation with you.
Yes - R-value is a standardized measurement, and we source from Owens Corning, Johns Manville, Knauf, Rockwool, and other manufacturers to hit your target without product lock-in. We’ll pull the ACCA Manual J from the truck and walk through why R-38 in an attic floor performs differently than R-38 in a cathedral ceiling if you want to understand the trade-offs.
Most clean removals with same-day replacement finish in one to two days; contaminated jobs requiring HEPA containment and substrate treatment typically run two to three days. We don’t schedule until the written price is accepted, and we text you when your named technician is en route.
Spot repair is rarely cost-effective with cellulose - once it’s settled, contaminated, or leached, the material can’t be restored to original performance. Removal and replacement with sealed bypasses upfront almost always yields lower utility bills and better indoor air quality than patching over compromised material. We’ll show you the blower-door numbers so you can see the difference.
We don’t stock proprietary GreenFiber inventory - we source cellulose and alternative materials from multiple suppliers, which means no back-order delays and no pressure to use a specific product. Your written scope names the exact material, R-value, and installed depth before work starts.
