How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes solid insulation products, but Los Angeles attics are brutal on any blown-in material. Here’s what we actually see when we open up an LA attic, product line by product line.
- InsulSafe SP settling below R-value after rodent or water damage. InsulSafe SP is a fiberglass blown-in product that performs well until something disturbs it. Rats love to tunnel through it; roof leaks mat it down. In Los Angeles, where the roof-to-attic temperature swing can hit 90 degrees in a single day, matted fiberglass loses loft fast. We remove the damaged sections, inspect the decking and baffles, then blow fresh material to the depth required for the R-value your home needs.
- TrueComfort blown-in fiberglass shifting away from eaves. TrueComfort is common in Los Angeles homes built in the 1990s and 2000s. The weak point is eave coverage: installers often under-fill the outer edges to keep soffit vents clear, then wind-driven air from Santa Anas pushes the loose fibers inward. We verify baffle placement and fill to the full depth at the perimeter, which is where most heat enters in the first place.
- CertainTeed cellulose absorbing moisture in poorly ventilated attics. CertainTeed’s cellulose products (often installed under the InsulSafe brand in some years) hold moisture when attic ventilation is inadequate. In neighborhoods like Van Nuys, Northridge, and the San Fernando Valley, we regularly see attics where the only ventilation is a single gable vent. That cellulose gets heavy, loses R-value, and eventually supports mold. Our fix includes assessing ventilation before we add material; no point blowing in new insulation into an attic that can’t breathe.
- Mixed-material attics from previous contractors. We find a lot of Los Angeles attics with a layer of old batt insulation under a layer of blown-in CertainTeed. The thermal boundary is uneven, and the batts compress under the loose fill. You paid for R-38 and you’re getting R-25 in practice. We remove or re-level the existing material and blow one consistent layer of CertainTeed product at the correct depth, measured with depth markers so you can verify it yourself.
- Air sealing gaps under old CertainTeed blown-in. CertainTeed’s own installation guides assume the attic floor is sealed before blowing. In our experience across Los Angeles, about seven in ten attics we inspect have open top plates, unsealed can light housings, or bare duct penetrations. Insulation over a hole is just a filter. We air seal as part of the job, then blow the material. That’s the difference between “insulated” and actually comfortable.
Our CertainTeed Blown In Insulation Process
Here’s exactly what happens when you call us for CertainTeed blown-in insulation in Los Angeles.
- 1
Call and talk to a person. A live human answers, 24/7. You tell us what’s going on: too hot upstairs, high bills, a rat problem, or you’re replacing old insulation. We schedule a walkthrough.
- 2
We inspect and diagnose. A background-checked, uniformed technician arrives with photo ID and a marked truck. We measure attic depth, check ventilation, identify your current material, and look for air leaks. You get a full explanation, not a sales pitch.
- 3
Written price before work starts. We tell you exactly what CertainTeed product we recommend, how many bags, what depth, and what it costs. The number is written down before any equipment comes off the truck. No post-job surprises, ever.
- 4
Prep and air seal. We seal the gaps that actually matter: top plates, wire penetrations, can light housings, duct boots. Then we set depth markers so you can verify the R-value with your own eyes.
- 5
Blow the CertainTeed material. Using calibrated equipment, we blow the material to the specified depth, working around baffles to protect ventilation. The machine stays outside; the mess stays in the attic.
- 6
Cleanup and the written guarantee. We walk the attic with you, confirm the depth and coverage, and hand you the 365-Day Done Right Promise in writing. If it’s not done right within a year, we come back and make it right at no charge.
What CertainTeed Blown In Insulation Costs in Los Angeles
Here are honest ranges for the CertainTeed blown-in jobs we do most often in Los Angeles. These are real numbers based on this market, not national averages.
| Job Type | Typical Range |
|---|---|
| Blow CertainTeed InsulSafe SP over existing insulation, 1,200 sq ft attic | $1,800 – $2,600 |
| Remove old insulation, air seal, blow CertainTeed TrueComfort to R-38, 1,200 sq ft | $3,200 – $4,200 |

What moves the price: attic access (scuttle holes vs. pull-down stairs), the condition of your existing insulation, whether air sealing is needed, and how much ventilation correction we have to make. If the price feels high, remember you’re not just buying fiberglass; you’re buying the person who knows where to put it and stands behind it for a year. Call (213) 376-3824 for an exact quote. Estimates are free, and the number we give you is the number you pay.
Why Los Angeles Homeowners Call Aspen Attic Insulation Los Angeles for CertainTeed Work
Plenty of insulation companies in Los Angeles will blow CertainTeed material into your attic. Few of them will put their name, face, and price in writing before the work starts.

FAQs
No, as an independent CertainTeed service provider, we install to the manufacturer’s specified depths and densities, which keeps any product warranty intact. We don’t cut corners on coverage, because a warranty claim that fails due to thin insulation is the homeowner’s problem, not CertainTeed’s. Call (213) 376-3824 and we’ll verify your warranty requirements before we quote.
We schedule most CertainTeed blown-in insulation jobs within three to five business days in Los Angeles, and same-week appointments are often available for simple top-ups. Our technicians arrive in a marked uniform with photo ID, and you’ll see their name and photo before they arrive.
Technically yes, but the machine rental, material cost, and air sealing work mean you’re usually saving less than $800 on a job that a trained crew can do in a day. We’ve fixed enough DIY attics to know that an uneven layer with missed air leaks costs more to correct than the original job would have. Call us for a written estimate first; you can always decide the savings aren’t worth the hassle.
For most Los Angeles attics, yes. Blown-in fiberglass fills gaps, covers irregular joist spacing, and reaches under low eaves that batts miss. CertainTeed’s InsulSafe SP and TrueComfort lines perform well in our climate, but the real factor is installation quality. A perfectly installed batt beats a badly blown product every time. We’ll tell you which one fits your attic and why.
We carry eight brands: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, plus Reflectix for radiant barrier applications. If CertainTeed is the right product for your attic, that’s what we’ll recommend. If another material fits better, we’ll tell you that too, with the price difference in writing. Call (213) 376-3824 for a free estimate.
