GreenFiber Home Energy Audit in West Hollywood: What to Know First
We provide independent GreenFiber home energy audit in West Hollywood, typically scheduling within 48 hours and completing the full diagnostic same-day. Most audits run between $280 and $520 depending on square footage and whether duct leakage testing is included. We are not affiliated with or authorized by GreenFiber - we are an independent GreenFiber service provider - which means we diagnose without a sales quota for replacement products.
This page is for homeowners in West Hollywood who have GreenFiber cellulose insulation in their attic or walls and need to know why their upstairs still runs hot, why their PG&E bill spiked after a mild month, or whether their insulation was installed correctly in the first place. We audit GreenFiber systems specifically: Low Dust, Sanctuary, and the older stabilized cellulose lines common in 2015-2020 retrofits around the Norma Triangle and West Hollywood West. Call (213) 306-2607 for a written price before any work starts.
How GreenFiber Products Fail - and How We Fix Them
- Low Dust settling in unsealed attics. GreenFiber Low Dust is engineered for reduced airborne particulate during installation, but in West Hollywood’s dry Santa Ana seasons it settles faster when blown over unsealed top plates. We find 15-20% thickness loss in five-year-old jobs near Melrose Heights. Our fix: pull back the cellulose, seal every penetration with fire-rated caulk and rigid baffles, then reinstall to labeled depth.
- Sanctuary line moisture retention in wall cavities. GreenFiber Sanctuary is treated with borate for pest resistance, yet its higher borate load can wick moisture when paired with vinyl siding and no rainscreen - common on 1960s duplexes along Santa Monica Boulevard. We identify this with thermal imaging and recommend either exterior remediation or a switch to a hydrophobic alternative like Rockwool if the wall cannot breathe.
- Stabilized cellulose binder breakdown in roof pitches. Pre-2018 GreenFiber stabilized cellulose used a water-activated adhesive that degrades with repeated attic heat cycling above 140°F - routine under dark composition shingles in West Hollywood summers. The material slumps off pitched ceiling joists, creating voids we map with borescope inspection. We remove the failed pack, re-secure with netting and proper vent chutes, then reinsulate.
- GreenFiber over can lights without ten-minute fire enclosures. GreenFiber is Class A fire-rated, but California Title 24 still requires ten-minute fire-rated enclosures or IC-rated fixtures before contact. We find this violated in roughly a third of West Hollywood audits, especially on quick flips near the Design District. We install proper enclosures, air-seal the housing, then replace the cellulose - never the reverse order.
- Compression from storage decking installed post-insulation. Homeowners add plywood platforms for holiday storage, compressing GreenFiber to half its labeled R-value. In West Hollywood’s small-lot homes where attic storage is precious, we build raised framing systems that maintain full depth beneath the deck, then supplement with additional cellulose or a hybrid layer of Reflectix radiant barrier where appropriate.
Our GreenFiber Home Energy Audit Process
- 1
Written price before arrival. We review your home’s age, square footage, and any prior insulation receipts by email or text. You get a flat audit price with scope in writing. No work starts without it - Haven Standard Clause 1.
- 2
Blower-door test - baseline. We pressurize the house to 50 pascals (a standard measurement of air leakage rate) and record the CFM50 reading. Most pre-1980 West Hollywood homes start between 3,500 and 6,000 CFM50.
- 3
Thermal imaging and insulation mapping. Our FLIR camera identifies GreenFiber voids, compressed areas, and thermal bypasses. We borescope wall cavities where settlement is suspected.
- 4
Duct leakage testing if applicable. We seal registers and pressurize the duct system to 25 pascals, measuring leakage to outside. In West Hollywood’s tight lots, leaky ducts in vented attics often lose 20-30% of conditioned air.
- 5
Written report with photo documentation. You receive a Documented Photo Record, the blower-door number, thermal images with annotations, and a prioritized scope with flat pricing for any remediation. If we do the work, we publish before-and-after blower-door numbers so you can verify the result.
- 6
365-Day Done Right Promise. If the performance doesn’t match the report, we return. Under Haven Standard: Have it in writing.
Before
AfterWhat GreenFiber Home Energy Audit Costs in West Hollywood
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Basic home energy audit (blower door + thermal imaging) | $280 - $380 | Home size under 1,500 sq ft vs. over; access difficulty in tight attics |
| Audit with duct leakage test | $380 - $520 | Number of HVAC systems; duct accessibility in crawl space or soffit |
| GreenFiber-specific borescope inspection (wall cavities) | $150 - $220 add-on | Number of test holes; plaster vs. drywall repair |
| Written remediation scope (included with audit) | No charge | - |
Factors that increase cost: homes over 3,000 square feet, multiple attic zones separated by firewalls (common in West Hollywood’s converted duplexes), and active rodent contamination requiring cleaning before insulation assessment.

Why West Hollywood Homeowners Call Topside Attic Insulation West Hollywood for GreenFiber Work
We’ve been inside more than a few bungalows off Santa Monica Boulevard - air-sealing the top plates before a single bag of cellulose goes in, because that’s the sequence that actually holds an R-value. Seal the leaks first. Then insulate. The R-value on the bag assumes you did it in that order.
Wes Okafor learned the building sciences side of this trade at Olive-Harvey College in Chicago before spending the better part of two decades doing attic work across the LA basin. His crew keeps a worn copy of the California Energy Code on the truck seat. We source GreenFiber when it fits the application, but we’re not locked to it - we also work with Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and Reflectix. Every job gets a written scope, a Documented Photo Record, and on air-sealing work, before-and-after blower-door numbers you can reference when your utility bill arrives. Calls are answered by a live person, 24/7.
FAQs
Will a GreenFiber audit void my insulation warranty?
No. GreenFiber’s limited warranty covers product defect, not installation error - and our audit documents condition without altering the material. If we find an installation issue (insufficient depth, missing air sealing), that documentation actually supports any claim you file with the original installer. Call (213) 306-2607 and we’ll review your warranty paperwork with you - estimates are free.
Can you get GreenFiber parts if my insulation needs supplementing?
Yes. GreenFiber Low Dust, Sanctuary, and stabilized cellulose are available through regional distributors in LA County. We are not a GreenFiber dealer - we are an independent service provider - so we source at wholesale and pass through without markup. If your home needs a different product to solve the actual problem, we’ll say so. Call for a written scope.
Is it cheaper to repair my GreenFiber installation or start over?
Repair is usually 40-60% less than full removal and replacement, but only if the existing cellulose is dry, uncontaminated, and accessible. In West Hollywood, we find repairable GreenFiber in about two-thirds of audits - the other third has rodent damage, moisture staining, or was installed at half the labeled depth. We give you both numbers in writing before you decide. Call (213) 306-2607 for an exact quote.
How fast can you audit a GreenFiber system in West Hollywood?
We typically schedule within 48 hours and complete the audit in 2-3 hours on site. Same-day emergency scheduling is available for active moisture intrusion or post-rodent situations where insulation compromise is suspected. You’ll have the written report and photo record within 24 hours. Call (213) 306-2607 - a live person answers.
Do you also service Reflectix insulation?
Yes. We audit and install Reflectix radiant barrier products alongside or in place of GreenFiber where the thermal profile calls for it - typically in West Hollywood’s unvented attics or where HVAC ducts run through the roofline. We are independent of Reflectix as well. Call for a written price on hybrid or alternative systems.
