CertainTeed Blown-In Insulation in Irvine: What to Know First
CertainTeed blown-in insulation in Irvine typically costs $1,800 to $4,200 for a full attic application, with top-up jobs running $900 to $2,100, and most are completed in a single visit. We’re an independent CertainTeed service provider, which means we work on the product because it’s good, not because a manufacturer tells us to. If your CertainTeed insulation has settled, gotten damp, or never performed the way the label promised, call (949) 832-7835 and a live person answers, 24/7. This page is for Irvine homeowners who already have CertainTeed blown-in insulation and need it topped up, removed, or diagnosed, and for those comparing CertainTeed against other blown-in options before committing.
How CertainTeed Products Fail - and How We Fix Them
CertainTeed makes solid insulation. We install it regularly. But every product has failure modes, and after working Irvine attics since 2011, we know exactly where CertainTeed blown-in products show their age or vulnerabilities. Here’s what we see most often:
- Settling in TrueComfort and InsulSafe SP fiberglass: CertainTeed’s blown fiberglass is fluffy and light, which is great for initial coverage but means it settles more than cellulose over time. In Irvine homes built before 2000, we regularly find attics where InsulSafe SP has dropped from R-38 to an effective R-22 or worse in the 15 years since installation. The fix is a density-corrected top-up, usually to the current California Energy Code minimum of R-38. We don’t just blow more on top; we check the existing depth in multiple spots because settling is never uniform across an attic.
- Cellulose moisture wicking in CertainTeed cellulose (GreenChoice): CertainTeed’s recycled-fiber cellulose performs well until a small roof leak or bathroom fan venting into the attic introduces moisture. Cellulose wicks that moisture outward fast, compacts, and loses most of its R-value in the affected area. In Woodbridge and other older Irvine neighborhoods, we’ve seen whole sections of attic insulation turn into damp, matted material from a leak the homeowner never noticed. The fix is removing the compromised material, addressing the moisture source, and reinstalling dry, treated cellulose or fiberglass at the correct density.
- Uneven coverage from DIY or hasty original installs: This isn’t a manufacturing defect, but we see it constantly with CertainTeed products because they’re sold at big-box stores and homeowners blow them in themselves. The center of the attic gets 14 inches, the eaves get 3. CertainTeed’s coverage charts assume even distribution, and that assumption fails in most real-world installs. We fix it with a calibrated machine, baffles at every soffit, and depth markers so the coverage is verifiable, not guesswork.
- Pest intrusion in loose-fill applications: Blown-in insulation, regardless of brand, is a comfortable home for rodents. In Irvine neighborhoods bordering the foothills and golf courses, rats and mice tunnel through CertainTeed blown-in material, creating voids and contaminating the insulation. We address this as part of the job: remove what’s damaged, treat for pests, seal entry points, then blow fresh material. CertainTeed doesn’t sell a rodent-proofing kit, but our attic cleaning and rodent proofing service handles the problem before new insulation goes in.
- Dense-pack wall applications with CertainTeed fiberglass: CertainTeed’s fiberglass can be dense-packed into walls, but it requires a specific blowing pressure and technique. Done wrong, you get voids and thermal bypasses that no amount of attic insulation can compensate for. We’ve corrected several Irvine jobs where an under-pressured dense-pack left entire stud bays with almost no material. The fix is drilling access holes, checking fill density with an IR camera, and re-blowing any deficient cavities to the manufacturer’s specified pounds-per-cubic-foot.
Our CertainTeed Blown-In Insulation Process
Here’s how a typical CertainTeed blown-in job goes from first call to final walkthrough:
- 1
Call and diagnosis: You call (949) 832-7835. A live person answers. We ask about your home’s age, current insulation type (if known), and what you’re experiencing: high bills, hot upstairs rooms, drafty walls. If it makes sense, we schedule a home energy audit to get actual measurements before touching anything.
- 2
Attic assessment: Our technician inspects the existing CertainTeed material, measures depth in multiple locations, checks for moisture, pest activity, and air leaks. We document everything with photos so you see what we see.
- 3
Scope and quote: We give you an upfront, line-item price. No vague “attics start at” language. You know what material, what R-value, and what the total is before we begin.
- 4
Prep and air sealing: We seal top plates, wire penetrations, and recessed can lights where safe, install baffles at soffits for ventilation, and protect any recessed fixtures that need clearance.
- 5
Blow-in at calibrated density: Using a commercial machine, we blow CertainTeed material to the depth that delivers true R-38 or higher, with depth markers placed so the coverage is measurable.
- 6
Test and verify: We re-measure depth across the attic, check for even distribution, and confirm the attic’s ventilation is still working. Then we walk you through what we did. If anything’s not right in 90 days, the 90-Day Done Right Promise means we come back and make it right.
What CertainTeed Blown-In Insulation Costs in Irvine
Pricing on CertainTeed blown-in work in Irvine depends on attic square footage, existing insulation condition, and whether we’re topping up or starting over. Here’s what we typically see:
- Blown-in top-up (existing insulation present): $900 to $2,100. This covers blowing additional CertainTeed fiberglass or cellulose to bring total depth to R-38.
- Full attic blow-in (new or removed-to-bare): $1,800 to $4,200 for a typical 1,200 to 2,200 square-foot Irvine attic. Larger homes with complex rooflines run higher.
- Removal of old or damaged CertainTeed insulation: $1.50 to $3.00 per square foot, depending on depth and condition. Wet, pest-contaminated, or heavily settled material costs more to remove safely.
- Dense-pack wall insulation with CertainTeed fiberglass: $2,500 to $6,500 for exterior wall retrofits, depending on wall area and access difficulty.
What moves the price: existing insulation depth, attic accessibility (low slope or truss-framed roofs take longer), pest remediation, and whether we’re air sealing as part of the job. We recommend air sealing on any full attic job because it doubles the comfort payoff for a modest added cost. Estimates are free. Call (949) 832-7835 for an exact number on your home.

FAQs
No. Topping up an attic with additional blown-in insulation, whether CertainTeed or another brand, does not void a CertainTeed product warranty on existing material. What voids warranties is improper installation, like covering recessed lights that aren’t IC-rated or blocking soffit vents. We install to code and manufacturer specs so your warranty stays intact.
Yes, we can match CertainTeed blown-in fiberglass or cellulose by R-value and material type. Fiberglass and cellulose can be blended in an attic if depths are adjusted correctly, but we typically recommend matching the existing material for consistency. Call (949) 832-7835 and we’ll tell you exactly what you have and what to add.
If your existing CertainTeed material is dry, pest-free, and not heavily settled, topping up is usually the more cost-effective route. If it’s matted, moldy, rodent-contaminated, or more than 30 years old, removal and replacement gives you a clean slate and better long-term performance. We’ll tell you which one your attic needs after we look at it, not before.
Most blown-in attic jobs in Irvine are done in one day, including removal if needed. Dense-pack wall work takes longer depending on house size. A live person answers our phones 24/7, so if you call (949) 832-7835 today, we can often schedule you within the week.
Yes, in most Irvine homes built before 2000, bringing attic insulation from R-19 or less up to R-38 cuts attic-related heat gain in summer and heat loss in winter by 30 to 50 percent. The exact savings depend on your home’s orientation, window area, and HVAC efficiency, but the attic is usually the single biggest weak point in older Irvine homes. A home energy audit gives you a measured baseline so you know what to expect before spending anything.
Yes. We offer $50 off any repair over $250, an $89 seasonal attic tune-up, and a permanent 5% discount for seniors and veterans. These apply to CertainTeed blown-in jobs just like everything else we do. Call (949) 832-7835 and we’ll walk you through what applies to your project.
