GreenFiber Home Energy Audit in Costa Mesa: What to Know First
We perform independent GreenFiber home energy audits in Costa Mesa, typically completing the full diagnostic in 60 to 90 minutes with a written report in hand before we leave. Most audits run between $199 and $349 depending on home size and how many tests you want included. You’ll get real numbers showing exactly where your house is leaking, plus plain-English recommendations you can act on now or phase in over time. This page is for Costa Mesa homeowners who already have GreenFiber insulation (or are thinking about it) and want to know if it’s actually doing its job. Call (657) 224-2897 and a live person answers, 24/7. No voicemail, no call center.
How GreenFiber Products Fail - and How We Find It
GreenFiber makes quality cellulose insulation. We’ve worked with it in Costa Mesa homes for over a decade, and when it underperforms, the cause is rarely the material itself. It’s almost always how it was installed, how it’s settled, or what’s happened to the house around it. Here’s what we see most often in audits:
- GreenFiber SANCTUARY settling below the intended depth. Cellulose settles. That’s normal. But in Costa Mesa attics with dramatic temperature swings between coastal fog mornings and 90-degree inland afternoons, we regularly find SANCTUARY blown-in insulation that has compacted well below the labeled R-value. A 12-inch install meant to deliver R-60 can settle to R-38 within five years if it was fluffed during installation rather than dense-packed. Our thermal imaging catches this immediately. Without it, you’d never know until your July electric bill tells you.
- GreenFiber Insulation Plus bridging at the soffit line. This is the single most common failure we document in Costa Mesa ranch homes from the 1960s and 70s. Installers blow to the edge, blocking soffit vents, and the attic stops breathing. Then you get condensation, then you get mold on the roof deck. The fix isn’t more insulation. It’s pulling it back, installing proper baffles, and re-blowing to the right density. We’ve done this on more than 200 Costa Mesa homes.
- Moisture migration into GreenFiber R-60 in cathedral ceilings. Costa Mesa’s marine layer isn’t just a morning nuisance. It’s a humidity source that moves into improperly air-sealed ceiling cavities. When GreenFiber gets damp, its R-value collapses and it stops recovering. Our blower door test paired with thermal imaging pinpoints the exact air channels letting that moisture in, usually around recessed can lights and bathroom fan housings.
- Pest intrusion into loose-fill GreenFiber in crawl spaces. Rats and mice love the stuff. In Costa Mesa neighborhoods near Fairview Park and along the Santa Ana River corridor, we regularly discover tunnels through GreenFiber that have completely compromised the thermal barrier. An audit identifies the trampled zones, and our rodent proofing plus removal and replacement service handles the rest. Material partners include Owens Corning and Rockwool if you want to switch to something less rodent-friendly.
- GreenFiber Insulation Star installed over old, degraded fiberglass. We see this in Costa Mesa homes where a previous owner got a “great deal” on a quick energy upgrade. New cellulose gets blown directly over old fiberglass batts that have compressed to R-11. The result is worse than either material alone. Our audit separates what’s actually performing from what’s just occupying space, and the fix is usually full removal and rebute with GreenFiber SANCTUARY.
Our GreenFiber Home Energy Audit Process
Every audit follows the same sequence, whether it’s a 900-square-foot bungalow near Wilson Street or a two-story near South Coast Plaza. Here’s what happens from first call to final report:
- 1
The call. You reach a live person. We ask about your home’s age, square footage, and what’s driving the audit: high bills, cold rooms, drafts, pests, or just wanting to know. We schedule a time that works, often same-week in Costa Mesa.
- 2
The walkthrough. Neil Ashford or one of our background-checked, uniformed technicians walks the property with you, inside and out. We look at attic access, crawl space condition, visible ductwork, and the age of your HVAC. We also note whether your GreenFiber is the SANCTUARY, Insulation Plus, or Insulation Star line, because it matters for what we expect to find.
- 3
The blower door test. We mount the calibrated fan in your front door and depressurize the house to 50 pascals. This tells us your exact air changes per hour, the number every energy code and utility rebate is built around. Most Costa Mesa homes built before 1990 test between 0.8 and 1.2 ACH50. Tight new construction runs closer to 0.2. We tell you your number and what it means in dollars.
- 4
Thermal imaging and duct leakage testing. We scan every wall, ceiling, and floor with an infrared camera while the house is depressurized. This reveals exactly where conditioned air is escaping and where insulation has failed. If you want duct numbers, we run a duct blaster test that quantifies how much conditioned air your ducts are losing, which in a Costa Mesa home with a 20-year-old HVAC system is often 25 to 40 percent.
- 5
The report. You get a room-by-room breakdown with thermal images, your infiltration number, your duct loss percentage, and a prioritized list ranked by what delivers the biggest comfort and bill impact per dollar spent. We tell you what needs doing now and what can wait. No scare tactics and no unnecessary upsells. If the audit shows your GreenFiber is fine, we say so.
- 6
The follow-up. Everything we recommend and then perform is covered by our 90-Day Done Right Promise. If it’s not right, we make it right. Most repair jobs that come out of an audit are completed in a single visit.

FAQs
Yes, and it’s exactly what we do on most Costa Mesa audits. We measure settled depth, check for moisture using a probe meter, scan with thermal imaging for voids and bridging, and use the blower door to measure how well the whole assembly is holding your conditioned air inside. You get a pass-or-fail verdict with numbers behind it. Call (657) 224-2897 to schedule and we’ll have a tech out this week.
In Costa Mesa, adding more GreenFiber SANCTUARY over existing dry, pest-free cellulose usually costs $1.50 to $2.50 per square foot, while full removal and replacement runs $3 to $5 per square foot. The deciding factors are moisture, mold, and rodent damage. If the existing material is contaminated, adding more locks the problem in. We’ll tell you which route your house actually needs after the audit. Estimates are free.
Most audits are scheduled within the same week, and we reserve several slots each week for Costa Mesa homeowners with an active problem like a wet attic or visible rodent damage. Emergency calls are answered by a live person 24/7, and if you have a situation that can’t wait, we’ll make time. Call (657) 224-2897 and we’ll get you on the schedule today.
No. Adding GreenFiber over existing insulation does not void any manufacturer warranty on the existing material, provided the existing insulation is dry and the attic ventilation remains intact. What does cause problems is blowing over damp or moldy material, which is why we always inspect before we recommend. Our audit gives you the full picture before a single bundle of anything gets moved.
Will the audit help me qualify for Costa Mesa or Southern California energy rebates?
It can. Several utility rebate programs in Southern California require documented blower door and duct leakage numbers before approving insulation or air sealing upgrades. Our full audit at $299 or $349 gives you exactly the documentation they ask for, with your name, address, and test results on a professiona
