Icynene Blown-In Insulation in West Hollywood: What to Know First
We provide independent Icynene blown-in insulation service in West Hollywood, typically completing most jobs same-day or next-day with a written price before any work starts. Most attic jobs in a home this size run between $1,800 and $4,200 depending on existing conditions, access, and whether air sealing is needed first. We are not affiliated with or authorized by Icynene; we are an independent Icynene service provider that sources materials from Icynene’s product line alongside Owens Corning, Johns Manville, and others.
This page is for West Hollywood homeowners who already have Icynene insulation in place and need blown-in work - whether that’s a top-up where settling has occurred, dense-pack wall insulation for a remodel, or replacement after moisture damage. If you’re seeing uneven temperatures, higher utility bills than last season, or your original Icynene installation was done before 2015, you’re the owner we wrote this for. Call (213) 306-2607 for a free estimate with a written price delivered before we start.
How Icynene Products Fail - and How We Fix Them
- Classic Max settling in vaulted ceilings. Icynene Classic Max, the open-cell spray foam line common in West Hollywood’s 1990s-2000s condo conversions, shrinks up to 2% over time in hot roof assemblies. When we find this in attics off Sunset Plaza or above Santa Monica Boulevard retail spaces, the gap between foam and roof deck creates a convection loop that defeats any blown-in top-up until we cut back the failed foam and re-establish contact. We remove the compromised Classic Max, seal the deck with closed-cell transition, then blow in cellulose to the proper depth.
- MD-R-200 moisture retention in crawl spaces. Icynene’s MD-R-200 medium-density formula was specified in several West Hollywood hillside builds where crawl space humidity runs high. The foam itself doesn’t fail structurally, but it can trap moisture against rim joists if the vapor retarder was omitted. We find this when homeowners report musty odors despite “good” insulation. Our fix: remove the affected MD-R-200, install a proper vapor barrier, then dense-pack the joist bays with treated cellulose that manages moisture through hygroscopic cycling.
- LD-C-50 overspray into soffit vents. The low-density LD-C-50 was popular for quick attic jobs in the 2010s, and we’ve seen it sprayed directly over vented soffits in multiple West Hollywood bungalows. The foam blocks intake airflow, creating attic moisture problems that mimic roof leaks. We cut away the vent-blocking foam, install proper baffles, then blow in fiberglass to maintain the vent channel. Without this step, you’re insulating over a moisture problem that will destroy the new material.
- ProSeal settling at top plates. Icynene ProSeal, the higher-density open-cell product, can pull away from top plates in seismic-active framing if the substrate wasn’t properly cleaned. West Hollywood’s older balloon-framed duplexes are especially prone. The gap at the plate becomes a thermal bypass that blower-door testing catches at 300-800 CFM50. We remove the separated ProSeal, mechanically fasten a seal at the plate with acoustical sealant, then dense-pack the wall cavity to restore the air barrier.
- Water-blown formulations and off-gassing complaints. Early Icynene water-blown foams in pre-2010 West Hollywood installs can emit trace amines if the mix was off-ratio or applied too thick in a lift. Homeowners report a “sweet” odor that persists. We don’t cover this with more insulation. We remove the affected material, ventilate the cavity to completion, then blow in Johns Manville or GreenFiber cellulose - materials with no post-installation emission profile.
Our Icynene Blown-In Insulation Process

- 1
Call and scheduling. A live person answers, 24/7. We schedule a site visit in West Hollywood within 24-48 hours. You’ll get a text when your technician is en route, with a name and photo.
- 2
Inspection and blower-door test. We pressurize the house to 50 pascals - a blower-door test that shows, in one number, how much air your building envelope is losing. We document existing Icynene product type, condition, and any failure modes. You get a Documented Photo Record of what we found.
- 3
Written price and scope. Before any work starts, you receive a flat price, written scope, and written warranty. This is Haven Standard Clause 1. No exceptions. We also offer a Free Second Opinion on any competing written estimate.
- 4
Air sealing first, then insulation. Seal the leaks first. Then insulate. The R-value on the bag assumes you did it in that order. We seal top plates, can lights, and penetrations before a single bag of cellulose or fiberglass goes in.
- 5
Blown-in installation with material selection. For Icynene-compatible work, we select from Icynene’s blown-in line or cross-reference with Owens Corning, Knauf, or GreenFiber depending on your existing system and performance goals. No proprietary lock-in.
- 6
Post-job verification and documentation. We run a second blower-door test and publish the before-and-after numbers. You walk away with the written scope, warranty, photo record, and pressurization readings. Under our 365-Day Done Right Promise, if it’s not done right, we make it right.

AfterWhat Icynene Blown-In Insulation Costs in West Hollywood
Most attic top-up jobs in West Hollywood run $1,800-$2,800 for a 1,000-1,500 square foot footprint with reasonable access. Dense-pack wall insulation in a typical 1,200 square foot bungalow runs $3,200-$4,200, higher if we need to remove failed Icynene foam first. Crawl space work with vapor barrier remediation starts around $2,400.
| Job Type | Typical Range | What Moves the Price |
|---|---|---|
| Attic blown-in top-up (cellulose or fiberglass) | $1,800 - $2,800 | Existing depth, access hatch location, air sealing needed |

| Crawl space with vapor barrier | $2,400 - $3,600 | Moisture damage extent, joist bay access |
| Icynene foam removal + replacement | Add $800 - $1,500 | Foam type, location, disposal requirements |

Wes Okafor learned the building sciences side of this trade at Olive-Harvey College in Chicago, then spent 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.
Our difference is documented, not declared. Every applicable job gets before-and-after blower-door numbers. Every visit gets a Documented Photo Record. Our 365-Day Done Right Promise is backed by a written warranty, not a handshake. We also service Reflectix and other brands, so if your Icynene system needs a hybrid solution, we won’t force a single-manufacturer fix. Calls are answered by a live person, 24/7. Background-checked, uniformed technicians. Named technician, text when they’re on the way.
FAQs
Independent service does not automatically void an Icynene warranty, but coverage is limited to original installation defects and requires documentation many homeowners don’t have. As an independent Icynene service provider, we document our work separately - your written scope and warranty from us stand on their own. Call (213) 306-2607 and we’ll review what you have.
We source from Icynene’s product line when it’s the right choice for the assembly, but we also use Owens Corning, Johns Manville, Knauf, and GreenFiber depending on your existing system and performance goals. We don’t do proprietary lock-in. The material spec is in your written scope before work starts.
Repair is cheaper when the failure is localized - settling at a top plate, a small overspray block, isolated moisture damage. Removal and replacement makes sense when the product is failing across the assembly or was installed with systemic errors like blocked ventilation. We’ll tell you which category you’re in after inspection, with a written price for both paths. Call (213) 306-2607 for a free estimate.
Most jobs are completed same-day or next-day once the written price is accepted. We stock common blown-in materials and our West Hollywood location means we’re not driving from the Valley. Emergency situations - active moisture intrusion, failed insulation exposing conditioned space - get priority scheduling.
You get four things: the written scope you approved, a written warranty under our 365-Day Done Right Promise, a Documented Photo Record of the work area before and after, and on applicable jobs, before-and-after blower-door readings showing the actual air-leakage reduction. Haven Standard: Have it in writing.
