GreenFiber Home Energy Audit Nationwide

GreenFiber Home Energy Audit in Campbell: What to Know First

A GreenFiber home energy audit in Campbell typically runs $280-$520, takes 2.5 to 4 hours on-site, and delivers a written report with blower-door numbers you can use for any contractor - or for us if you choose to move forward. We are an independent GreenFiber service provider; we do not represent the manufacturer. This page is for Campbell homeowners who already have GreenFiber cellulose or stabilized insulation in their attic or walls and want to know whether it is performing, whether it was installed over unsealed leaks, and what it would actually cost to fix the problems the audit finds. Call (831) 534-3206 to schedule; estimates are free, and we bring a written price to every visit.

How GreenFiber Products Fail - and How We Fix Them

• GreenFiber All Borate loose-fill cellulose settling below labeled R-value in Campbell’s variable humidity. The South Bay’s dry summers and winter moisture swings cause cellulose to compact 15-20% over the first three years, especially in older Campbell attics with board sheathing that breathes more than modern OSB. We measure settled depth against the bag label’s design thickness, then calculate whether top-up or removal makes sense. Seal the leaks first. The insulation has nowhere useful to go until you do.
• GreenFiber Stabilized cellulose bridging over unsealed top plates in 1960s-1980s Campbell ranch homes. Stabilized product is sprayed with adhesive to resist settling, but that same binding can create a crust layer that hides gaping air paths at wall top plates - the horizontal framing member where exterior and interior walls meet the ceiling. Our blower-door test pinpoints these leaks; we cut back the crust, seal with fire-rated caulk and rigid blocking, then re-apply.
• GreenFiber Low Dust formula installed directly over recessed can lights without airtight enclosures. Low Dust reduces installer irritation but does not change the fact that old non-IC cans in Campbell’s original housing stock leak conditioned air straight into the attic. We pull back around every fixture, install Tenmat or similar fire-rated covers, seal the penetration, then replace the insulation.
• GreenFiber borate-treated product compromised by rodent activity in crawl spaces near the Los Gatos Creek corridor. Borate resists mold and pests, but persistent roof rat traffic compresses tunnels through the material, destroying its loft and creating uninsulated voids. Our audit includes a documented photo record of compression patterns; we remove contaminated sections, rodent-proof with hardware cloth, then reinstall.
• GreenFiber installed as a dense-pack wall fill without prior air-sealing of electrical penetrations. Dense-pack cellulose in Campbell’s stucco-over-wire-lath walls can perform well, but electricians’ holes for switches and outlets become express lanes for air if not foamed first. We run a thermal imaging scan during the blower-door test to spot these bypasses; remediation means minimal drywall intrusion, not whole-wall teardown.

Our GreenFiber Home Energy Audit Process

1. 1
   Schedule and scope. Call (831) 534-3206; a live person answers. We confirm square footage, insulation type if known, and any symptoms - hot rooms, high bills, dust from vents. You get a named technician and a text when they are en route.
2. 2
   Pre-work blower-door test. We depressurize the house to 50 Pascals and record CFM50 - the cubic feet per minute of air leakage at standard test pressure. This number goes on your report before we touch anything.
3. 3
   Thermal imaging and physical inspection. With the house under pressure, we scan with FLIR for insulation voids, air bypasses, and moisture patterns. We photograph GreenFiber depth, condition, and any installation defects.
4. 4
   Duct leakage test if applicable. If your HVAC runs through the attic, we pressurize the duct system and measure leakage to outside. Campbell homes with flex duct in hot attics often lose 20-30% of conditioned air before it reaches the register.
5. 5
   Written findings and price. Before we leave, you receive a documented photo record, the blower-door reading, and a flat written price for any recommended work. No work starts without it - Haven Standard Clause 1.
6. 6
   Post-repair verification. If you hire us for remediation, we run a second blower-door test and hand you a printed report showing the before-and-after CFM50. Every applicable job gets this.

What GreenFiber Home Energy Audit Costs in Campbell

Homes near the Pruneyard Plaza corridor or in Campbell’s older 95008 pockets often need more time for access through original attic hatches - we price this in, not discover it later.

Why Campbell Homeowners Call Topside Attic Insulation Campbell for GreenFiber Work

We have sealed and insulated 9,000+ homes since 2016, and the ones in Campbell taught us something specific: the 1950s-1970s stock here was built fast, insulated late if ever, and often received GreenFiber or similar blown-in products as a retrofit without the air-sealing step that makes them function. Wes Okafor, our owner, spent his early South Bay years working attic assemblies from San Jose to Los Gatos before focusing on Campbell; he still runs the blower-door tests himself on complex jobs. We publish before-and-after blower-door numbers on every applicable job - not a marketing claim, a printed report you hold. The 365-Day Done Right Promise covers all work. We also service Reflectix and other brands, so our recommendations are not locked to any single manufacturer’s product line. Calls are answered live, 24/7.
