GreenFiber Insulation Removal & Replacement in Seguin: What to Know First
We provide independent GreenFiber insulation removal and replacement in Seguin, with most attic jobs completed in one day and a written price delivered before any work starts. Typical GreenFiber removal and replacement in a Seguin home runs between $2,800 and $5,400 depending on attic square footage, contamination level, and whether the original install skipped air sealing. This page is for homeowners who know they’ve got GreenFiber cellulose in their attic and need it out, whether it’s settled, contaminated, or simply past its useful life. Call us at (830) 549-6646 for a free estimate with a written scope.
How GreenFiber Products Fail - and How We Fix Them
- GreenFiber All Borate loose-fill cellulose settling below R-value. In Seguins heat and humidity cycles, All Borate can settle 15-20% over its first decade, creating thin spots near eaves and over top plates where thermal imaging shows blue. We remove the settled material, seal the attic floor properly, then reinstall to a measured, even depth with density-checked blowing.
- GreenFiber Sanctuary blown-in wool/cellulose blend absorbing moisture in unvented cathedral ceilings. The Sanctuary line performs well in dry assemblies, but in Seguins older homes with ridge vent blockages or bathroom fans vented into attics, the wool content holds moisture against drywall. We remove the compromised material, diagnose and fix the moisture source, then replace with a material suited to the actual assembly conditions.
- GreenFiber stabilized cellulose losing fire-retardant borate treatment after rodent contamination. When rodents nest in stabilized cellulose, their urine neutralizes the borate salts that provide fire resistance and pest deterrence. We remove all contaminated material, sanitize the substrate, rodent-proof the attic with steel mesh at penetration points, then install fresh insulation with restored chemical protection.
- GreenFiber subfloor insulation in crawl spaces falling from moisture and pest activity. The subfloor batts GreenFiber produced for crawl space use sag and detach when humidity exceeds 70% for extended periods, common in Seguin crawl spaces during spring and fall. We remove the fallen material, install a proper vapor barrier if absent, then replace with a moisture-tolerant solution.
- Original GreenFiber installs blown over unsealed top plates and can lights. This is not a product failure but an installation failure we see constantly in Seguin homes built 1995-2010: GreenFiber was blown in without first sealing the thermal bypasses. The insulation appears intact but performs poorly. We remove enough material to access and seal all top plates, electrical penetrations, and fixture boxes with fire-rated caulk and rigid foam, then reinstall.
Our GreenFiber Insulation Removal & Replacement Process

- 1
Call and scheduling. A live person answers, or you can text. We schedule a site visit in Seguin, typically within 48 hours.
- 2
Attic inspection and blower-door test. We run a blower-door test - a pressurization reading that shows, in one number, how much conditioned air your building envelope is losing. We document existing GreenFiber type, depth, condition, and all thermal bypasses with photos.
- 3
Written scope and price. You get a flat price, written scope, and written warranty before anyone lifts a tool. This is Haven Standard Clause 1, no exceptions.
- 4
Removal and air sealing. We remove GreenFiber material using HEPA-contained vacuums, then seal all top plates, wire penetrations, can lights, and chimney chases with appropriate fire-rated materials.
- 5
Replacement and verification. We install replacement insulation to specified depth and density, then run a second blower-door test. The report goes home with you - the numbers do the talking.
- 6
Cleanup and documentation. We deliver your Documented Photo Record and the printed pre- and post-installation report with ACH50 numbers. The 365-Day Done Right Promise begins.
Before
AfterWhat GreenFiber Insulation Removal & Replacement Costs in Seguin
Most GreenFiber removal and replacement jobs in Seguin fall between these ranges:
| Scenario | Typical Range |
|---|---|
| Partial removal, localized contamination (1-2 areas) | $1,800 - $2,800 |
| Full attic removal and replacement, standard ranch | $2,800 - $4,200 |

| Crawl space removal and encapsulation add-on | $2,200 - $3,600 additional |
What moves the price: attic square footage, accessibility (truss height and hatch size), contamination requiring HEPA protocols, extent of air sealing needed, and whether the original install included a proper vapor barrier. We also service Reflectix products if your assembly includes radiant barrier components that need attention during the same project.

Why Seguin Homeowners Call Topside Attic Insulation Seguin for GreenFiber Work

We’ve sealed and insulated over 9,000 homes since 2016, and the ones in Seguin keep teaching us something. The Hill Country edge has specific conditions: limestone substrate that shifts framing, humidity that finds every gap, and older neighborhoods near Guadalupe Regional Medical Center where balloon framing and unsealed top plates are the rule, not the exception. Wes Okafor learned the building science side of this trade at Triton College in River Grove, IL, and that foundation means we don’t blow insulation over problems - we document them, fix them, then prove the fix with before-and-after blower-door numbers. Background-checked, uniformed technicians. Live person on the phone, 24/7. Written price before any work starts. The report goes home with you.
FAQs
GreenFiber’s product warranty covers manufacturing defects, not installation or removal by third parties. As an independent GreenFiber service provider, we document the condition of existing material with photos before removal, so any valid manufacturing claim can still be pursued. If you’re concerned about warranty status, call us at (830) 549-6646 and we’ll review your documentation during the free estimate.
Yes. We source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber itself - no proprietary lock-in. We specify replacement R-value based on your attic’s actual geometry and Seguins climate zone requirements, not just matching a bag label. Call (830) 549-6646 for the exact specification we’ll use in your home.
Spot repairs are cheaper upfront but rarely solve the underlying problem. In Seguin, we most often find that GreenFiber issues trace back to unsealed air leaks or moisture sources that make partial repairs a short-term fix. We quote both options when feasible, but our written scope will flag why the cheaper path may cost more over time. Call (830) 549-6646 for a free estimate with both approaches priced out.
Most GreenFiber removal and replacement jobs in Seguin are completed in one day once scheduled. We typically inspect within 48 hours of contact and schedule work within one week. Same-week availability happens when a crew is already in your neighborhood. Call (830) 549-6646 to check current scheduling.
We can reinstall GreenFiber products or specify an alternative based on your attic’s conditions and your preference. In Seguin homes with chronic moisture issues, we often recommend Rockwool or a spray foam hybrid for specific assemblies where cellulose has underperformed. No proprietary lock-in means the material choice is based on performance, not brand obligation. Call (830) 549-6646 to discuss options during your free estimate.
