GreenFiber Home Energy Audit Nationwide

GreenFiber Home Energy Audit in Mountain View: What to Know First

We provide independent GreenFiber home energy audit in Mountain View, typically scheduling within 48 hours and completing the full diagnostic same day. Most audits run $280-$450 depending on home size and test scope, and you’ll get a written price before we start - no exceptions. This page is for GreenFiber owners in Mountain View, Los Altos, and Sunnyvale who want to know whether their cellulose insulation is performing as specified, or whether air leaks are undermining the R-value they paid for.

How GreenFiber Products Fail - and How We Fix Them

• Low-Spray stabilized cellulose settling in vaulted ceilings. GreenFiber’s Low-Spray series, common in Mountain View’s Eichler and post-war ranch stock, can drop 15-20% from its installed depth within five years when moisture cycling from Pacific fog pushes through inadequate soffit ventilation. We measure settled depth with a probe, calculate the effective R-value loss, and recommend either top-dressing with fresh GreenFiber All Borate or switching to a denser pack if the cavity allows.
• All Borate treated cellulose losing fire-retardant salts to roof leaks. The borate chemistry that gives GreenFiber its Class 1 fire rating washes out slowly from pinhole leaks around chimney flashings or failed tile underlayment - something we see regularly in Mountain View’s older Rex Manor and Monta Loma roofs. Our thermal camera spots the salt-depleted zones as cooler patches, and we mark them for spot replacement rather than full removal.
• Insulation Shield baffles compressed by blown-in depth. GreenFiber’s own vent baffles, installed to keep soffit intakes clear, get crushed when subsequent contractors add insulation without checking. We pull back material, reinstall or replace baffles with rigid proper vents, and re-blow to the correct depth - usually 10-14 inches for R-38 in this climate zone.
• Cocoon cellulose bridging over irregular joist bays. In the kneewalls and dropped soffits common to Mountain View’s second-story additions, Cocoon can leave voids where it doesn’t contact the sheathing. Our blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - catches these voids as unexpected leakage paths, and we dense-pack them with a hose extension.
• GreenFiber installed over unsealed top plates and can lights. This isn’t a product failure; it’s a sequencing failure we correct. We’ve found original GreenFiber installations in Mountain View’s 1950s-1970s stock where the attic floor was never sealed first. The insulation has nowhere to go if the air does. We pull back material, seal every penetration with fire-rated caulk and rigid foam, then replace the cellulose.

Our GreenFiber Home Energy Audit Process

1. 1
   Call and schedule. A live person answers 24/7. We book a two-hour window and text when our technician is en route.
2. 2
   Visual and thermal inspection. We walk the attic with a FLIR camera, probe GreenFiber depth at six or more locations, and photograph every anomaly. You get these photos.
3. 3
   Blower-door test. We depressurize the house to 50 pascals and record the CFM50 reading - the baseline. Then we use a smoke pencil to locate the largest leakage paths.
4. 4
   Duct blaster if indicated. When flex duct runs through the attic, we test for leakage to outside. GreenFiber performance depends on conditioned air actually reaching the rooms.
5. 5
   Written scope and price. Before any work starts, you receive a flat price, written warranty, and documented photo record. Haven Standard Clause 1: no exceptions.
6. 6
   Air sealing first, then insulation. We seal, re-test to verify reduction, then add or replace GreenFiber as specified. The after blower-door number goes on your invoice.

What GreenFiber Home Energy Audit Costs in Mountain View

What moves the price: attic accessibility (scuttle vs. pull-down stairs), presence of active rodent contamination requiring cleaning, and whether we find failed baffles or compromised fire-retardant zones that need addressing. We also service Reflectix radiant barrier systems when they’re part of the same envelope. Call (669) 259-0406 for a free estimate - we’ll read any competing written quote with you.

Why Mountain View Homeowners Call Topside Attic Insulation Mountain View for GreenFiber Work

We’ve been in Mountain View’s Rex Manor neighborhood pulling out compacted fiberglass batts and replacing them with properly staged blown-in cellulose - the kind of job where the before-and-after blower-door numbers tell the whole story. Wes Okafor, our owner and lead technician, grew up on Chicago’s South Side and picked up his trade fundamentals at Richard J. Daley College before spending the better part of two decades working insulation jobs up and down the San Francisco Peninsula. His crew sequences every job the same way: air-seal every penetration at the attic floor before a single pound of insulation goes in, then hand the homeowner a written report showing the pre- and post-job ACH50 figure. The 365-Day Done Right Promise applies to all work, and we publish blower-door numbers on every applicable job so you can verify the performance change you paid for. We’re an independent GreenFiber service provider - not affiliated with or authorized by the manufacturer - which means we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber with no proprietary lock-in.
