This page is for Los Angeles homeowners who already have CertainTeed insulation, or are weighing it against other brands, and want straight answers on cost, performance, and what actually works in our specific climate. If your upstairs rooms run ten degrees hotter than your downstairs in August, the problem isn’t your HVAC. It’s what’s between your ceiling and your roof. Neil Ashford has spent over a decade diagnosing exactly that, and we’ll tell you what we’d do if it were our house.

How CertainTeed Products Fail - and How We Fix Them

CertainTeed makes good insulation. But even good products underperform when they’re installed wrong, aged, or paired with a leaky attic floor. Here’s what we actually see in Los Angeles homes, and what we do about it.

• InsulSafe Fiberglass settling and loss of R-value. CertainTeed’s InsulSafe fiberglass loose-fill is designed to maintain its loft, but we regularly find attics where it was blown in below the minimum depth for our zone, or where years of foot traffic and roof leaks have compressed it. A settled 6-inch layer performs like a 4-inch layer, and R-30 becomes R-19 in practice. We check depth with a calibrated gauge, then top up to the correct depth for Los Angeles, which typically means R-38 or better.
• TrueComfort Cellulose and rodent damage. CertainTeed’s TrueComfort cellulose is treated with borates, but rats and squirrels in neighborhoods like Silver Lake and Highland Park don’t read the spec sheet. We’ve pulled out cellulose nests chewed into tunnels, which destroys the thermal barrier and leaves droppings throughout the attic. Our fix includes removal of the compromised material, rodent proofing, and a fresh TrueComfort blow-in, not just patching over the problem.
• Missing fire-blocking around recessed lights and flues. This is an installation failure more than a product failure, but it’s common in older Los Angeles homes where CertainTeed was blown in without proper shielding around can lights and chimney penetrations. It’s a fire risk and a code issue. We install UL-rated covers and maintain proper clearance before any blow-in job.
• Moisture-saturated insulation from flat-roof leaks. CertainTeed fiberglass loses its insulating ability entirely when wet, and L.A.’s flat-roofed mid-century homes are notorious for slow roof leaks that go unnoticed until the insulation is soaked. Wet InsulSafe feels heavy and mats flat against the drywall. We identify the moisture source first, remove the damaged material, and only then blow in fresh insulation. Blowing new over wet is throwing money away.
• Inconsistent coverage from DIY or rushed installs. We see attics where someone blew CertainTeed insulation themselves and left bare spots behind ductwork, around the perimeter of the attic, or over the garage. The brand is fine; the coverage is not. Our techs map the attic floor, mark duct runs and junction boxes, and blow to a consistent, measured depth across the entire space.

Our CertainTeed Blown-In Insulation Process

1. 1
   Call and diagnosis. You call (213) 782-8141 and a live person answers, not a voicemail. We talk through your symptoms: hot rooms, high bills, drafts, critters in the attic. If a home energy audit makes sense, we recommend one, but we’ll never push it if the problem is obvious.
2. 2
   Attic inspection. A background-checked, uniformed technician walks your attic and measures current insulation depth, checks for moisture, rodent activity, air leaks around penetrations, and condition of any existing CertainTeed material. You get photos and plain-English findings, not a sales pitch.
3. 3
   Air sealing first. If the attic floor has gaps around plumbing stacks, wiring, and interior walls, we seal them before any insulation goes in. Blown-in insulation doesn’t stop airflow; air sealing does. This is the step most contractors skip and the step that makes the biggest difference in a Los Angeles summer.
4. 4
   Blow-in installation. We run the hose up and blow CertainTeed InsulSafe or TrueComfort to the agreed depth, using depth markers so coverage is even and consistent. We route around ductwork, shielding recessed lights and keeping proper clearance from flues.
5. 5
   Verification and cleanup. We measure the final depth at multiple points, photograph everything, and clean up completely. Then we walk you through what we did and why.
6. 6
   90-Day Done Right Promise. If anything isn’t right, you call us and we make it right. That’s our written commitment, and we’ve stood behind it since 2011.

What CertainTeed Blown-In Insulation Costs in Los Angeles

Here’s what we quote in the field, based on the jobs we do across Los Angeles from the Palms area up through the Valley and across to the Eastside. These are real ranges; your exact price depends on square footage, depth, access, and condition of your current insulation.

• Full attic blow-in, 1,000-1,500 sq ft home: $1,800-$2,800
• Full attic blow-in, 1,500-2,500 sq ft home: $2,400-$3,800
• Top-up over existing insulation (to R-38): $900-$1,600
• Insulation removal and replacement (rodent damage or moisture): $2,800-$5,000
• Attic air sealing before blow-in: $600-$1,200

What moves the price: attic size, how much old insulation needs removal, whether we’re air sealing, and access difficulty, like a tight crawl-in attic with no walkway. We quote upfront, no surprises, and most jobs are done in one visit. Call (213) 782-8141 for an exact number. The estimate is free, and a real person answers.
