Icynene Wall Insulation in West Hollywood: What to Know First
We provide independent Icynene wall insulation service in West Hollywood, typically scheduling within 48 hours and completing most jobs in a single day. Most Icynene injection foam or drill-and-fill wall projects in a West Hollywood home this size run between $2,800 and $5,400, and we deliver a written price before any work starts. This page is for homeowners who already have Icynene products in their walls and need to know whether the existing foam can be supplemented, replaced, or paired with new material to hit target R-value. If you’re seeing cold spots along exterior walls in your 1920s Spanish or your 1960s courtyard apartment off Melrose, call (213) 306-2607 for a free estimate and a written scope.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max shrinks in West Hollywood’s dry heat cycles. The open-cell formulation can pull back from studs after repeated seasonal expansion and contraction, leaving thin channels where air bypasses the insulation entirely. We diagnose this with thermal imaging, then drill-and-fill the gaps with compatible open-cell foam or switch to a closed-cell injection depending on wall cavity depth.
- Icynene MD-R-200 (medium-density closed cell) develops adhesion failure on stucco exteriors common north of Santa Monica Boulevard. The rigid foam separates from the substrate when moisture drives through old portland cement plaster with no drainage plane. We remove the failed sections, install a vapor-smart barrier where code allows, and re-inject with matching density so the wall breathes correctly for this climate.
- Icynene H2Foam Lite absorbs moisture in unvented rainscreen assemblies. That half-pound open cell was never meant to sit against a wet sheathing plane without drying potential. We find the water source first - usually failed flashing at a deck ledger or window head - seal it, then replace saturated foam and upgrade to a closed-cell system if the assembly permits.
- Icynene LD-C-50 (low-density open cell) sags in tall wall cavities. In West Hollywood’s vertical additions and two-story townhomes, the lightweight foam can settle several inches over five to seven years, creating an uninsulated cap at the top plate. We access through minimal interior drywall cuts, remove the settled material, and re-install with proper cavity fill depth confirmed by borescope inspection.
- Icynene spray foam installed over unsealed top plates leaks conditioned air regardless of R-value. The foam itself is intact, but air whistles past electrical penetrations and plate gaps the original installer skipped. We pull back where needed, seal with acoustic sealant and gasketed boxes, then restore the thermal boundary. Seal the leaks first. Then insulate. The R-value on the bag assumes you did it in that order.
Our Icynene Wall Insulation Process
- 1
Call and schedule. A live person answers 24/7. We book a site visit, usually within 48 hours in West Hollywood.
- 2
On-site assessment with thermal imaging and borescope. We identify the Icynene product line, measure remaining foam depth, and locate air bypass paths. You get a written price before any work starts - Haven Standard Clause 1.
- 3
Parts decision: OEM Icynene or compatible aftermarket. We stock Demilec and CertainTeed closed-cell products that interface correctly with existing Icynene when OEM lead times run long, and we document the compatibility rationale in writing.
- 4
Air sealing first, then insulation. Top plates, electrical penetrations, and any cavity openings get sealed before new material goes in. We pressurize to 50 pascals with a blower door to verify the seal.
- 5
Injection or drill-and-fill with depth verification. Every cavity gets confirmed full by borescope. We photograph before, during, and after.
- 6
Final blower-door test and documentation. You receive the pre- and post-job CFM50 readings, the photo record, and the written warranty under our 365-Day Done Right Promise.

West Hollywood’s mix of R-1 zoning bungalows and denser courtyard housing means cavity depths vary from 3.5 inches to 5.5 inches after furring - that single variable changes material volume by 40 percent. We measure before we quote. Call (213) 306-2607 for an exact written price - estimates are free, and we offer a Free Second Opinion on any competing written estimate.
Why West Hollywood Homeowners Call Topside Attic Insulation West Hollywood for Icynene Work
We’ve been inside walls from the Norma Triangle to West Hollywood Heights, and we’ve learned that Icynene jobs fail when the installer treats foam as a substitute for air sealing rather than a complement to it. Our crew includes technicians who trained on Icynene’s own product data before working with the broader open-cell and closed-cell market - including Reflectix radiant barrier systems when a hybrid assembly makes more sense for a south-facing stucco wall in July.
Every job closes with a Documented Photo Record and, on applicable work, before-and-after blower-door numbers you can compare to your next utility bill. The 365-Day Done Right Promise is in writing before anyone starts. Background-checked, uniformed technicians. Calls answered by a live person, 24/7. No voicemail loops.
FAQs
Icynene’s product warranty covers manufacturing defects regardless of who installs it, but workmanship coverage requires an Icynene-certified contractor. As an independent Icynene service provider, we document our material batch numbers and installation conditions so you have a clear chain of evidence if a product claim arises. We also provide our own 365-Day Done Right Promise on labor. Call (213) 306-2607 to review warranty specifics for your product line.
Yes - we regularly source compatible closed-cell foam from Demilec and CertainTeed with matching density and R-value per inch, and we verify thermal performance with post-install testing. We never substitute without written approval and documented compatibility data. For a free second opinion on material options, call (213) 306-2607.
Spot injection into settled or shrunken Icynene runs 40 to 60 percent less than full removal and replacement, but only if the remaining foam is dry and well-adhered. Saturated or chemically degraded foam must come out - there’s no reliable way to bond new material to compromised old. We borescope first and give you both options in writing. Call (213) 306-2607 for an assessment.
Most jobs schedule within 48 hours and finish in one day. Two-day timelines apply for full removal jobs requiring drywall repair or stucco cut-and-patch. We don’t start without a written price, so the scope is fixed before the crew arrives. Call (213) 306-2607 to check current availability.
Yes - we’ve done Icynene injection and soundproofing work in West Hollywood’s 1960s courtyard apartments and newer TIC conversions. Multi-family jobs require HOA or property management coordination on wall assemblies, and we provide the documented photo record and written scope that most boards require for approval. Call (213) 306-2607 to discuss your building.
