GreenFiber Home Energy Audit Nationwide

GreenFiber Home Energy Audit in Boerne: What to Know First

We provide independent GreenFiber home energy audit in Boerne, typically completed same-day with written results delivered before we leave. Most audits run between $280 and $550 depending on home size and test scope, and we publish every blower-door reading so you can verify the finding yourself. This page is for GreenFiber owners in Boerne who want to understand why their insulation isn’t performing the way the bag promised, and what a proper diagnostic looks like before anyone suggests adding more. Call (830) 529-7780 to schedule - a live person answers, 24/7.

How GreenFiber Products Fail - and How We Fix Them

• Low-Slope Settling in SANCTUARY Loose-Fill: SANCTUARY cellulose is marketed at R-3.7 per inch, but in Boerne’s Hill Country heat it can settle 15-20% in the first two summers when installed over an unsealed attic floor. The R-value drops; the homeowner sees a $40-$80 summer bill spike before they notice the insulation looks thinner. We pull back settled SANCTUARY, seal top plates and can-light penetrations with fire-rated foam, then reinstall to proper depth with density verification.
• Moisture Uptake in Humid Crawl Spaces: GreenFiber’s stabilized cellulose contains borate treatment, but in vented crawl spaces around Boerne’s Cibolo Creek basin, seasonal humidity above 70% overwhelms the borate buffer. The material clumps, loses loft, and can support mold on the paper backing of adjacent batts. We encounter this in 1980s ranch homes near River Road Park. Our fix: remove compromised material, install a proper vapor barrier, then switch to closed-cell spray foam or Rockwool if the crawl space can’t be fully encapsulated.
• Thermal Bridging Where SANCTUARY Meets Top Plates: GreenFiber’s loose-fill doesn’t address the wood-to-wood heat path at exterior wall top plates - a 1.5-inch gap that reads 15-20°F colder on our FLIR camera during a Boerne August afternoon. Homeowners blame the cellulose; the real problem is air moving through the plate gap, carrying conditioned air out and attic heat in. We seal with ZypFoam or equivalent fire-rated caulk before any new insulation goes in.
• Duct Contact with GreenFiber in Tight Attics: In Boerne’s older homes near Main Street, flex ducts often rest directly on SANCTUARY at the attic floor. The cellulose compresses to R-2 or less under the duct weight, and the contact point becomes a condensate risk when attic dew points spike. We suspend ducts with proper strapping, replace compressed material, and verify with blower-door that the duct boot isn’t pulling attic air into the supply.
• Insulator-Grade Skipping of Air Sealing: GreenFiber’s installation guidelines specify air sealing first, but we’ve audited three Boerne homes in the last eighteen months where a previous contractor blew SANCTUARY directly over unsealed recessed housings and plumbing stacks. The blower-door numbers barely moved. We extract the new material, seal properly, and reinstall - documenting the before-and-after CFM50 so the homeowner sees exactly what the first crew skipped.

Our GreenFiber Home Energy Audit Process

1. 1
   Schedule and scope confirmation. You call (830) 529-7780; we confirm square footage, year built, and any known comfort complaints. We send a written price range before arrival - Haven Standard Clause 1, no exceptions.
2. 2
   Pre-work blower-door test. We depressurize the house to 50 pascals and record CFM50 - the single number that tells us how much conditioned air is escaping through the envelope. In Boerne’s 1990s subdivisions, we typically see 3,500-5,500 CFM50 before any work.
3. 3
   Thermal imaging and insulation inspection. FLIR scan identifies thermal bypasses: missing insulation at eaves, compressed GreenFiber at duct contact points, unsealed top plates. We photograph everything for the Documented Photo Record.
4. 4
   Duct leakage testing (when indicated). We pressurize the duct system and measure leakage to outside. GreenFiber homes with ducts in vented attics often leak 20-35% of conditioned air - you’re paying to cool your attic.
5. 5
   Written findings and prioritized scope. You get a printed report with blower-door number, thermal images, and a ranked fix list. No generic recommendations - each item ties to a specific finding in your home.
6. 6
   Post-repair verification (if we do the work). After air sealing and any insulation correction, we rerun the blower door and hand you the before-and-after comparison. Seal the envelope first. Then fill it.

What GreenFiber Home Energy Audit Costs in Boerne

Homes near the Cibolo Nature Center with original 1980s construction and no prior air sealing typically land at the higher end of audit and sealing ranges - more penetrations, more bypasses, more hours. We also service Reflectix installations and can compare your GreenFiber performance against radiant barrier alternatives if your roof geometry suits it. Every estimate is free; every price is written before work starts.
