GreenFiber Blown-In Insulation Nationwide

GreenFiber Blown-In Insulation in Schertz: What to Know First

We provide independent GreenFiber blown-in insulation service in Schertz, with most attic jobs completed in one day and pricing put in writing before any work starts. A typical GreenFiber cellulose top-up or full replacement in a Schertz home runs between $1,800 and $4,200 depending on attic square footage, existing depth, and whether the attic floor has been properly air-sealed first.

This page is for homeowners in Schertz who already have GreenFiber cellulose or fiberglass in their attic and need to add, replace, or troubleshoot it. We work on GreenFiber products as an independent service provider - we are not affiliated with or authorized by GreenFiber - and we also service Reflectix and other major brands when the job calls for it.

How GreenFiber Products Fail - and How We Fix Them

• GreenFiber All Borate Cellulose settling below labeled depth. The All Borate line is treated with mineral borate for fire resistance, but in Schertz’s high-humidity shoulder seasons, we’ve measured settled depths running 15-20% below the bag’s stated coverage chart. The cellulose compresses where attic dew points spike, especially above bathrooms and kitchen soffits. We fix this by mapping actual depth with a calibrated stick every 16 inches on center, then calculating true R-value recovery rather than simply blowing to the original depth mark.
• GreenFiber Sanctuary blow-in fiberglass stratification in cathedral ceilings. Sanctuary fiberglass - the white, loose-fill product - separates by density in angled assemblies over Schertz’s older ranch-style homes on FM 1518. The heavier glass nodules settle to the low side, leaving bare spots at the ridge. We find this with thermal imaging during our pre-work inspection, then dense-pack the cavity or switch to stabilized cellulose if the geometry won’t hold uniform fill.
• GreenFiber subfloor adhesive failure in raised-floor applications. When GreenFiber is used as crawl-space insulation in Schertz’s clay-heavy soils, the netting or twine support system fails where seasonal soil expansion shifts the floor joists. We see this in 1980s-era homes near the Cibolo Creek basin. Our fix is removing the dropped material, sealing the rim joist with closed-cell foam, then reinstalling with mechanical fastening that doesn’t rely on soil-stable framing.
• GreenFiber All Borate moisture absorption after roof leaks. Borate-treated cellulose wicks water laterally faster than fiberglass, which means a small ridge vent leak can saturate a 6-foot radius before the ceiling stains show. In Schertz, where wind-driven rain hits from the southeast off I-10, we’ve stripped out water-logged All Borate that weighed 4 pounds per square foot - double its dry weight. We remove to substrate, dry the deck with forced air, then replace only after verifying the leak source with a hose test.
• GreenFiber product confusion leading to incompatible top-ups. Homeowners sometimes add new GreenFiber over old material from a different manufacturer, or mix cellulose and fiberglass without understanding the coverage multiplier difference. The GreenFiber bag calls for one machine setting; the existing material may need another. We core-sample the existing insulation, identify it under magnification if necessary, and match the new product or remove the old to avoid density mismatches that reduce effective R-value.

Our GreenFiber Blown-In Insulation Process

1. 1
   Pre-work inspection and blower-door test. We pressurize the house to measure CFM50 - the single number that tells us how much conditioned air is escaping through the attic floor. In Schertz’s older homes near Live Oak Road, we regularly see starting readings above 3,500 CFM50.
2. 2
   Air-sealing before insulation. We seal top plates, wire penetrations, can-light housings, and chimney chases with fire-rated caulk and rigid blocking. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it.
3. 3
   Product selection and written price. We specify GreenFiber by line - All Borate, Sanctuary, or stabilized wall-fill - and note whether we’re using OEM material or a quality aftermarket equivalent with matching thermal specs. You get the written price, scope, and warranty before anyone starts.
4. 4
   Installation with depth verification. The crew blows to marked depth sticks placed every 100 square feet, then photographs each stick for the Documented Photo Record. We verify uniform coverage with thermal imaging before we leave.
5. 5
   Post-install blower-door test and documentation. On applicable jobs, we run the blower door again and publish the before-and-after numbers. You walk away with the photo log, depth verification, and a printed thermal-imaging summary.
6. 6
   Cleanup and 365-Day Done Right Promise activation. The crew vacuums the access path, reinstalls the hatch with weatherstrip if needed, and leaves the written warranty and Done Right Promise terms.

Why Schertz Homeowners Call Topside Attic Insulation Schertz for GreenFiber Work

We’ve been working the Schertz corridor for several years now, including jobs in the Sedona subdivision off FM 1518 where summer attic temps regularly push past 140°F before a single batt goes in. Wes Okafor built this operation on sequencing the work correctly: blower-door test first, air-sealing second, insulation third. Our crews are background-checked and uniformed, and a live person answers calls 24/7 - no voicemail loops, no callback windows measured in business days.

We source GreenFiber, Reflectix, Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and others, so we’re not locked into one manufacturer’s product line when your home needs something different. Every job since 2016 has started with a written price and ended with a documented record. The 365-Day Done Right Promise applies to all completed work - if it’s not done right, we make it right.
