Rockwool Home Energy Audit Nationwide

Rockwool Home Energy Audit in Morgan Hill: What to Know First

We provide independent Rockwool home energy audit in Morgan Hill, typically completed same-day with written results delivered before we leave. Most audits run between $280 and $550 depending on home size and test complexity, and we publish before-and-after blower-door numbers on every job where air sealing is part of the scope. This page is for Rockwool owners in Morgan Hill who want to know whether their Comfortbatt or AFB insulation is performing as specified, or whether gaps in the building envelope are making that R-value meaningless.

How Rockwool Products Fail - and How We Fix Them

• Comfortbatt settling in kneewalls and bonus rooms. Comfortbatt’s semi-rigid batts rely on friction fit against stud bays; in Morgan Hill’s older hillside homes near Oakwood Avenue, seasonal humidity swings cause wood framing to expand and contract, loosening the batt edge and creating a convection channel. We find this with thermal imaging and fix it with compression-correct reinstall plus targeted air sealing at the perimeter, not by stuffing more material into a gap that will just reopen.
• AFB (Acoustical Fire Batts) moisture uptake in crawl spaces. AFB is hydrophobic but not waterproof; in Morgan Hill’s clay-heavy soils where crawl space vapor pressure runs high in spring, we’ve seen AFB batts wick moisture from liquid contact at the sill plate rather than vapor diffusion. The fix is never “dry it out and reinstall.” We replace affected sections, install a proper vapor barrier on the ground, and seal rim joists before any new insulation goes in.
• Rockwool cavity fill incomplete at electrical penetrations. Rockwool’s density makes it less forgiving than fiberglass around romex runs and outlet boxes. Our blower-door tests regularly show thermal bypasses at these points in Morgan Hill’s 1990s-era tract homes off East Main, where electricians cut batts to fit rather than splitting around wires. We pull, seal the penetration with fire-rated caulk, and reinstall with proper technique.
• Top-plate gaps invisible above Rockwool attic layers. Homeowners see a full blanket of Rockwool Comfortbatt or blown-in Granulated Rockwool and assume the attic is done. But the top plates - where interior walls meet the ceiling drywall - are often unsealed beneath that layer. Our blower-door test catches this: a reading above 3,500 CFM50 in a 2,000-square-foot Morgan Hill home almost always points to this detail. We lift the Rockwool, seal the plates with foam, and replace the insulation undisturbed.
• Granulated Rockwool displacement from wind-washing at soffit vents. In Morgan Hill’s wind-prone canyon locations, we’ve measured attic air speeds that shift loose-fill Rockwool away from eaves, creating bare spots the homeowner can’t see from the hatch. Our fix includes proper baffles, re-leveling the granulated fill, and verifying with thermal imaging that the R-value is continuous to the edge.

Our Rockwool Home Energy Audit Process

1. 1
   Call and scope. A live person answers, 24/7. We ask square footage, year built, and any known comfort issues. You’ll get a written price range by text or email before we schedule.
2. 2
   Arrival and walkthrough. Our technician texts when en route. We inspect the Rockwool installation visible in attic, crawl, and walls, noting product line and installation quality without disturbing it yet.
3. 3
   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. In Morgan Hill’s 1970s-1990s housing stock, we typically see 3,800-5,200 CFM50 before any sealing work.
4. 4
   Thermal imaging and duct blaster (if ducts are accessible). We map insulation gaps, air leaks, and duct leakage with FLIR imaging. For Rockwool homes with ducting in unconditioned attics, we add a duct leakage test to the scope.
5. 5
   Written findings and next steps. You get a documented photo record, the blower-door number, and a flat-price proposal for any air sealing or insulation correction. No work starts without your written approval.
6. 6
   Completion and verification. If we perform sealing work, we rerun the blower door and publish the before-and-after so you can verify the change you paid for.

• Basic audit (blower door + thermal imaging): $280-$380 for homes under 2,500 square feet with accessible attics.
• Full audit with duct leakage test: $420-$550 for homes with HVAC ducting in unconditioned space, common in Morgan Hill’s hillside builds.
• Multi-zone or complex geometry: Add $80-$150 for homes with conditioned bonus rooms, multiple attic hatches, or crawl space access restrictions.
