Icynene Blown In Insulation Nationwide

Icynene Blown In Insulation in Los Angeles: What to Know First

Icynene blown in insulation in Los Angeles typically runs $1.80 to $3.40 per square foot installed, and most attic jobs are completed in one day. We’re an independent Icynene service provider, not a manufacturer-authorized dealer, which means we recommend what actually works for your home rather than what a brand program tells us to push. If you own a home with Icynene insulation and you’re noticing uneven temperatures, rising energy bills, or suspect your attic insulation has settled or underperformed, this page will tell you exactly what’s happening and what it costs to fix. Call (213) 376-3824 for a written estimate before any work begins.

This page is for Los Angeles homeowners who already have Icynene in their attic or walls and need to understand their options. You’ll learn how Icynene products age in our specific climate, what failure looks like, and what a proper blown in insulation job should include when paired with existing spray foam.

How Icynene Products Fail – and How We Fix Them

Icynene makes good insulation, but no product is perfect forever. In Los Angeles attics, where summer temperatures regularly push past 140 degrees, we see specific failure patterns. Here’s what actually goes wrong:

• Icynene Classic Plus shrinkage at roof deck seams. The open-cell formula that made this line popular for its sound-dampening properties can shrink slightly at edges where it meets framing. In Los Angeles homes built between roughly 2005 and 2015, we regularly find quarter-inch gaps along rafter bays where conditioned air escapes. The fix is usually a blown in cellulose or fiberglass top-up over the existing foam to seal the thermal boundary, not a full tear-out.
• Icynene ProSeal settling under attic flooring. When closed-cell foam gets covered by plywood decking for storage, homeowners assume it’s fine. But if the original install left voids (common when installers worked around recessed lights or junction boxes), heat finds those gaps fast. We remove the decking section, verify the foam coverage, and blow loose-fill into any cavity that reads below R-value on our thermal imaging pass.
• Rodent intrusion through Icynene open-cell. Rats and mice chew through open-cell foam easily. In neighborhoods like Sherman Oaks, Studio City, and parts of the Valley, we see Icynene Classic Plus torn up by rodents looking for nesting space. Our fix involves removing contaminated foam, sealing entry points with exclusion material, then blowing in fresh insulation treated with a pest deterrent.
• Incomplete original coverage in hard-to-reach eaves. Icynene installs require the foam to reach every corner. In Los Angeles attics with complex rooflines and shallow eaves (common in Spanish Revival and mid-century homes), original installs frequently skipped tight spots. We use blown in fiberglass or cellulose to fill those narrow cavities, which is faster and less invasive than trying to re-spray foam into a cramped space.
• Moisture-compromised Icynene at bathroom exhaust vents. When bathroom fans vent into the attic instead of outside, open-cell Icynene absorbs that moisture. Over a few Los Angeles winters, the foam gets heavy, loses R-value, and can sag. We identify the vent issue first, correct it, then remove and replace the damaged section with blown in material that handles intermittent humidity better.

Our Icynene Blown In Insulation Process

Here’s exactly how a job runs when you call us about your Icynene insulation in Los Angeles:

1. 1
   Call and schedule a walkthrough. A live person answers at (213) 376-3824, day or night. You’ll get the technician’s name and photo before the visit, so you know who’s coming to your door.
2. 2
   Attic inspection and thermal imaging. We check the existing Icynene coverage, look for gaps, settling, moisture damage, and rodent activity. Garrett Sloane and the team verify actual R-values rather than guessing.
3. 3
   Written price, no surprises. You get a line-item quote before any work starts. It covers what we’ll remove, what we’ll add, and what it costs. No post-job add-ons.
4. 4
   Parts and materials decision. If we’re topping up or filling gaps, we match the blown in material to your existing Icynene setup. Sometimes that’s fiberglass for attic floors, sometimes cellulose for sidewall cavities. We carry stock from eight brands: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so the right material goes in, not just whatever’s on the truck.
5. 5
   Installation and cleanup. We blow the insulation to the specified depth, verify coverage with a second thermal pass, and leave your attic cleaner than we found it. Drop cloths go down, debris goes out with us.
6. 6
   365-Day Done Right Promise. Every job carries a written guarantee covering labor and materials for a full year. If it’s not done right, we make it right. Free second visit if anything fails.

What moves the price? Attic accessibility, whether existing foam needs removal, the depth required to hit Los Angeles code minimums (R-30 for attics), and whether we’re working around stored belongings.
