This page is for homeowners who already have GreenFiber cellulose in their attic and need more of it, or who are comparing GreenFiber against other blown-in options for a first install. We are not affiliated with or authorized by GreenFiber. We are an independent service provider who sources GreenFiber through normal distribution channels and installs it to the manufacturer’s density and coverage specs.

How GreenFiber Products Fail - and How We Fix Them

• Sanctuary settled below labeled R-value. GreenFiber’s Sanctuary line is common in Converse homes built 2015-2020, and we find it settled to 60-70% of its original depth after 5-7 years in our heat. The cellulose compresses where attic temperatures regularly hit 140°F in July, creating thermal valleys over hallway ceilings and master bedrooms. We remove the settled material, air-seal the attic floor properly, then reinstall to true labeled depth with a density check every 100 square feet.
• Low Dust formula clumping around bath fan penetrations. GreenFiber Low Dust cellulose resists airborne particles during install, but in Converse’s humidity swings it can clump where bathroom exhaust fans vent into attic space rather than through the roof. The clumped material holds moisture and compresses to half its R-value. We relocate the vent to proper termination, seal the penetration with fire-rated foam, then replace the clumped section with fresh material at manufacturer-specified density.
• Cocoon settling away from kneewall edges. GreenFiber Cocoon, the stabilized cellulose line, relies on a water-activated binder that cures in place. In older Converse ranch homes near Foster Road, we see binder breakdown where roof leaks or condensation have introduced moisture before our arrival. The material pulls back from vertical kneewalls and creates a 6-8 inch gap. We document the moisture source, repair it, remove the degraded Cocoon, and reinstall with a vapor retarder where building code requires it.
• Insulator GF machine-applied density inconsistencies. The GreenFiber Insulator GF system is designed for machine-blowing at 1.6 lbs per cubic foot, but rental machines in the San Antonio market are often calibrated for generic cellulose at 1.2 lbs. We see Converse homeowners who had a “good deal” blow-in that settled 25% in the first year because the material was under-densified. We strip and reinstall at proper density, measured with a scale and box test, not eye-balled.
• Fire-resistant treated cellulose dusting through recessed can lights. GreenFiber’s borate fire treatment is stable, but when it’s blown over unsealed IC-rated can lights the fine particles migrate through housing gaps into living space. We see this in Converse homes with 1980s-1990s remodels where original fixtures were never properly sealed. We remove material around each fixture, seal with fire-rated covers and caulk, then reinstall - keeping the borate where it belongs.

Our GreenFiber Blown-In Insulation Process

1. 1
   Call and scheduling. A live person answers, or you text us. We schedule a site visit with a named technician and text when they’re en route - Haven Standard: Arrive on schedule.
2. 2
   Attic inspection and blower-door test. We pressurize the house to 50 pascals and measure air leakage in CFM50. Wes Okafor started running these tests before and after every job because a picture of a thermal bridge caught on infrared is easier to explain than a paragraph, but the number is what holds us accountable.
3. 3
   Written price and scope. You get a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1. No exceptions.
4. 4
   Air sealing first. We seal top plates, can lights, penetrations, and chimney chases with fire-rated materials. We do not blow insulation over an unsealed attic floor. Seal the leaks first. Then insulate. The numbers will tell you if it worked.
5. 5
   GreenFiber installation to spec. We calculate required bags from manufacturer coverage charts, verify machine calibration, and check density with a scale and test box. OEM GreenFiber or quality equivalent - no proprietary lock-in.
6. 6
   Post-test, photo record, and cleanup. Second blower-door test shows the improvement. You get printed CFM50 before-and-after, a Documented Photo Record of the work, and a clean attic. The 365-Day Done Right Promise applies from that moment.

What GreenFiber Blown-In Insulation Costs in Converse

These ranges reflect what we see in Converse homes - from 1,400 square foot ranches near FM 78 to newer two-story builds in Woodlake. The price goes up when we find unsealed top-plate penetrations, the gaps where walls meet the attic floor, that were bleeding conditioned air long before anyone touched the blown-in cellulose. We tell you before we start, not after. Call (830) 420-0953 for a written estimate - free, no obligation.
