GreenFiber Home Energy Audit in Morgan Hill: What to Know First
We provide independent GreenFiber home energy audit in Morgan Hill, typically completed same-day with written results delivered before we leave. Most audits run between $280 and $450 depending on home size and test scope, and you’ll get a written price before we start - no exceptions. This page is for Morgan Hill homeowners who have GreenFiber insulation or are considering it and need to know exactly how their building envelope is performing. Call (669) 280-8103 to schedule or get a free second opinion on any written estimate you’ve already received.
How GreenFiber Products Fail - and How We Fix Them
- Low-Settle Formula settling below labeled R-value in older Morgan Hill ranch homes. GreenFiber’s Low-Settle cellulose can lose 10-15% of its installed thickness over 7-10 years, especially in the dry Santa Clara County climate where thermal cycling is aggressive. We measure actual depth against the bag count and settled density, then calculate whether you’re still getting the R-38 or R-49 you paid for. If not, we remove the settled material or supplement with fresh blown-in, but only after sealing the attic floor - adding new fiber over a leaky deck just accelerates the next settlement cycle.
- Sanctuary blown-in bridging over top plates and electrical chases. GreenFiber’s Sanctuary line, common in Morgan Hill’s 2015-2020 builds off East Main, is marketed as pest-resistant but doesn’t stop air movement. We’ve found blower-door readings 800-1,200 CFM50 higher than they should be because the installer blew right over unsealed top plates. Our fix: pull back the fiber, seal every penetration with fire-rated caulk and foam, then reinstall. The insulation holds what you’ve already captured.
- All Borate fire retardant degrading in high-moisture crawl spaces. GreenFiber uses all-borate treatment, which is effective until relative humidity stays above 70% - something we see in Morgan Hill homes with crawl space vapor barriers that failed or were never installed. The borate doesn’t “fail” visibly, but the cellulose compresses and its thermal resistance drops. We test with a moisture probe and thermal camera, then recommend encapsulation before reinsulating. Installing fresh GreenFiber over a damp crawl space is expensive decoration.
- Loose-fill density inconsistencies from DIY or non-specialist installation. GreenFiber loose-fill requires 1.6-1.8 lbs per cubic foot for rated performance. In the Oakwood Avenue area, we’ve opened attics where the previous crew clearly varied the machine settings, creating thermal stripes visible on our FLIR camera. We map the attic with density probes, mark the thin spots, and reinstall to spec - again, after sealing.
- Wall-Spray shrinking away from studs in two-story Morgan Hill townhomes. GreenFiber’s damp-spray wall product can shrink 3-5% as it dries, leaving gaps at stud edges that become thermal bypasses. We find these with blower-door-directed infrared: depressurize the house, scan the walls, watch the cold stripes appear. The fix is targeted dense-pack retrofit, not another layer of spray.
Our GreenFiber Home Energy Audit Process
- 1
Call and scope. A live person answers, asks square footage, year built, and any known issues. We schedule a two-hour window and text when the technician is en route - Haven Standard: Arrive on schedule.
- 2
Blower-door test first. We install the calibrated fan in an exterior door and measure CFM50 - the cubic feet per minute of air leakage at 50 pascals of pressure. This single number tells us how much conditioned air your Morgan Hill home is hemorrhaging before we open the attic hatch.
- 3
Thermal imaging under pressure. With the house depressurized, we scan walls, ceilings, and rim joists with a FLIR camera. On GreenFiber jobs, we’re looking specifically for settlement patterns, density gaps, and the telltale cold stripes that mean air is moving through or around the insulation.
- 4
Insulation inspection and density check. We probe actual depth, check for moisture staining or pest intrusion, and photograph everything. If it’s GreenFiber, we note the product line and compare installed depth against the labeled settle-corrected thickness.
- 5
Written findings and price. You get a Documented Photo Record, the blower-door number, and a flat-price proposal before any work starts. If the fix is outside our scope - say, duct replacement or HVAC sizing - we say so plainly.
- 6
Work and re-test. On applicable jobs, we run the blower door again after sealing and document the CFM50 reduction. Most Morgan Hill homes drop 25-40% after proper air sealing.
What GreenFiber Home Energy Audit Costs in Morgan Hill
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Standard home energy audit (blower door + thermal imaging + insulation inspection) | $280-$350 | Home size under 2,500 sq ft, single attic, accessible crawl |
| Extended audit with duct leakage testing | $380-$450 | Two HVAC systems, hard-to-access duct runs, zoned systems |
| GreenFiber-specific density verification and supplementation | $180-$320 additional | Depth shortfall, area coverage, access difficulty |
| Crawl space moisture assessment with encapsulation quote | $150-$220 additional | Crawl size, existing vapor barrier condition, standing water |
Homes above 3,500 square feet or with multiple attic spaces run higher. We don’t estimate over the phone for complex jobs - we estimate in person, in writing, for free. Bring us any written estimate you’ve received; we’ll read it with you. Call (669) 280-8103.
Why Morgan Hill Homeowners Call Topside Attic Insulation Morgan Hill for GreenFiber Work
We’ve logged jobs in Morgan Hill neighborhoods from the older homes near Oakwood Avenue to the newer construction off East Main, and we’ve seen how GreenFiber performs in both. Wes Okafor, our owner and lead technician, learned blower-door diagnostics at Olive-Harvey College in Chicago before touching a bag of cellulose - that sequence matters. We don’t blow insulation over unsealed attics. We publish before-and-after blower-door numbers on every applicable job. Our 365-Day Done Right Promise applies to all work, and our materials include GreenFiber, Owens Corning, Johns Manville, Knauf, Rockwool, and Reflectix - no proprietary lock-in means we recommend what’s right for your house, not our supplier contract. Calls are answered live, 24/7.
FAQs
No. GreenFiber’s product warranty covers manufacturing defects, not diagnostic testing. As an independent GreenFiber service provider with no manufacturer affiliation, our audit doesn’t trigger any warranty clause - we’re inspecting performance, not making product claims. If we find an installation issue that should fall under your builder’s or original installer’s warranty, we document it with photos and blower-door data you can use in that conversation. Call (669) 280-8103 if you need help interpreting what we find against your paperwork.
Most Morgan Hill homeowners get an appointment within 48 hours, and the audit itself takes 2-3 hours. Same-day scheduling happens when our calendar allows - call (669) 280-8103 and we’ll tell you honestly what’s open. We don’t do callback windows measured in business days; a live person answers and books you.
Repair and supplement if the fiber is dry, uncontaminated, and settled less than 20% below labeled thickness. Remove and replace if we find moisture damage, rodent intrusion, or fire-retardant degradation - common in Morgan Hill crawl spaces with failed vapor barriers. The audit gives you the numbers to decide: actual R-value remaining, air leakage rate, and moisture content. We’ll show you the thermal images and explain both paths with flat prices for each.
GreenFiber doesn’t make “parts” in the traditional sense - it’s a loose-fill or damp-spray cellulose product. For supplementation, we can match GreenFiber’s specifications exactly or specify an equivalent from Owens Corning, Johns Manville, or Knauf if your job benefits from different density or fire-retardant chemistry. We don’t claim exclusive or preferred status with any brand. The choice is documented in your written scope before work starts.
A Documented Photo Record of all accessible areas, your before blower-door CFM50 reading, a thermal image summary with problem areas marked, a written scope with flat price for any recommended work, and a written warranty if you proceed. Haven Standard: Have it in writing. No report is “available on request” - it’s delivered before we leave or emailed same day.
