CertainTeed Blown-In Insulation in West Hollywood: What to Know First
We provide independent CertainTeed blown-in insulation service in West Hollywood, typically completing attic jobs in one day with a written price delivered before any work starts. Most CertainTeed blown-in cellulose or fiberglass top-ups in West Hollywood run between $1,800 and $3,400 for a typical 1,200-1,800 square foot attic, depending on whether air sealing is needed first. Call (213) 306-2607 for a free estimate with a written scope.
This page is for homeowners who already have CertainTeed insulation in their attic or walls and need more of it, different performance from it, or help with what’s failing. If you’re researching blown-in insulation brands and landed here, you’re also in the right place. We work with CertainTeed products daily in West Hollywood, from the bungalows south of Santa Monica Boulevard to the multi-family conversions near Melrose.
How CertainTeed Products Fail - and How We Fix Them
- InsulSafe SP settling in cathedral ceilings. This blown fiberglass is common in West Hollywood’s 1960s-1980s pitched roofs, and we’ve found it packed to half its labeled depth where roof pitch exceeds 6:12. The product didn’t fail; gravity won. We remove the settled material, install vent baffles to maintain the air gap the manufacturer requires, then reblow to true depth with a depth marker photo in your documented record.
- TrueComfort cellulose bridging over irregular joist bays. In the older West Hollywood stock with true 2×6 or 2×8 joists spaced at odd intervals, TrueComfort can bridge across gaps rather than filling them, leaving thermal bypasses. We dense-pack these bays with a hose technique that breaks the bridge, or switch to dense-pack wall methodology in attics with severe irregularity. The blower-door test afterward proves the bypass is gone.
- Optima GreenSeal losing R-value after rodent activity. West Hollywood’s mature tree canopy and alley access mean roof rats find attics seasonally. Optima’s borate treatment deters them, but disturbed cellulose compacts where they tunnel. We don’t just add more on top; we remove contaminated sections, seal entry points with steel mesh, then reblow. Adding fresh insulation over compacted, soiled material is how you get a 30% performance loss in two years.
- CertainTeed membrane-style attic covers degrading in heat. The reflective membrane products CertainTeed distributed in the 2010s (often paired with blown-in underneath) delaminate in West Hollywood’s attic temperatures, which regularly exceed 140°F in August. We remove the failed membrane, verify the blown-in below is still performing, and replace with a current radiant barrier solution or additional blown-in to compensate if the membrane was doing actual work.
- Density failures in originally contractor-installed blown-in. CertainTeed specifies 0.5 pounds per cubic foot minimum for wall dense-pack and 0.3 for open attic. West Hollywood retrofits from the 2000s often test below this, especially where installers rushed to finish before a rain forecast. We core-sample existing insulation with a tube cutter, weigh it, and document the density. If it’s low, we extract and reblow to spec, or note in writing that the existing material meets density and focus on air sealing instead.
Our CertainTeed Blown-In Insulation Process
- 1
Call and scheduling. A live person answers (213) 306-2607 24/7. We schedule a site visit in West Hollywood, usually within 48 hours. You receive a text with the technician’s name when they’re en route - Haven Standard: Arrive on schedule.
- 2
Attic 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) and enter the attic with a photo rig. We note CertainTeed product type, depth, density where questionable, and all air leakage paths: top plates, can lights, chimney chases, duct boots.
- 3
Written price and scope. Before any work starts, you get a flat price, written scope, and written warranty. This is Haven Standard Clause 1. No exceptions. If you have a competing estimate, we provide a free second opinion and read it with you.
- 4
Air sealing first. Seal the leaks first. Then insulate. The R-value on the bag assumes you did it in that order. We seal all accessible penetrations with fire-rated caulk, foam, or metal flashing as code requires. The blower-door test repeats after sealing; you get both numbers.
- 5
Blown-in installation to CertainTeed spec. We install your specified CertainTeed product - InsulSafe SP, TrueComfort, Optima - to labeled depth and density, with depth markers and photos. If we’re topping existing CertainTeed, we verify compatibility and document the interface.
- 6
Final test, photo record, and walkthrough. Applicable jobs get a post-work blower-door reading. Every job gets a Documented Photo Record delivered digitally. We walk you through what was done, what the numbers mean, and what to expect on your next utility bill.

Why West Hollywood Homeowners Call Topside Attic Insulation West Hollywood for CertainTeed 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. Wes Okafor built this operation on blower-door testing and written documentation, not on how long we’ve been around. The 365-Day Done Right Promise applies to every CertainTeed job: if it’s not done right, we make it right, backed by the written scope and warranty you already have in hand.
We also work with Reflectix and other brands, so if your CertainTeed product has been discontinued or a different material suits your assembly better, we’ll say so and show you why. No proprietary lock-in. Background-checked, uniformed technicians. Calls answered by a live person, 24/7.
FAQs
No. CertainTeed’s product warranties cover material defects, not who installed them, provided installation met manufacturer specifications. We install to CertainTeed’s published density and depth requirements and document both, so your warranty position is protected. If you have a specific warranty concern, call us at (213) 306-2607 and we’ll review your documentation with you.
We stock InsulSafe SP and TrueComfort for same-day completion on most West Hollywood jobs. Optima and specialty blends typically arrive next business day from the regional distributor in Vernon. We’ll tell you exactly which product is available when during your estimate, not after we’ve started.
Repair is cheaper when the existing material is dry, uncontaminated, and at or near specified density. Removal and replacement is necessary when there’s rodent activity, water staining, or density failure below 0.3 pcf in attics or 0.5 pcf in walls. We core-sample and give you a real number, not a guess. Call (213) 306-2607 for a free assessment.
Usually yes, and when we can’t - certain Optima blends were regionally limited in the 2010s - we document the interface and use a compatible product with equal or better R-value per inch. We never bury incompatible materials without noting it in writing.
Yes, on every job where air sealing is performed. You get the pre-work CFM50, the post-sealing CFM50, and the post-insulation CFM50 if we ran a third test. It’s the single figure that shows whether the work actually reduced infiltration. Wes Okafor started this practice because customers told him they wanted proof, not promises.
