Owens Corning Attic Insulation: The Woodland Hills Owner’s Guide
If you’re searching for Owens Corning attic insulation in Woodland Hills, you either need it installed, topped off, or replaced, and you want to know what it’ll actually cost. Installed pricing for Owens Corning fiberglass batt or blown-in insulation in Woodland Hills typically runs $1,400 to $3,800 depending on square footage, current R-value, and whether we’re air-sealing the attic floor first. We stock Owens Corning products on our trucks, and most attic insulation jobs in Woodland Hills are completed same-day.

Here’s how most homeowners land on this page: the upstairs bedrooms won’t hold temperature, the AC runs constantly from June through October, and they’ve finally looked up and realized their attic insulation is compressed, patchy, or practically gone. Sometimes they just bought the house and the inspector flagged it. Either way, the problem is rarely the Owens Corning brand itself. It’s usually the install, the age, or what the Woodland Hills heat did to it over two decades.
Key Takeaways:
- We install and replace Owens Corning fiberglass batts, rolls, and blown-in (ProPink and AttiCat systems)
- Most Woodland Hills jobs finish same-day with a written price before work starts
- Laurel Attic Insulation is an independent contractor, not affiliated with Owens Corning
- Every job includes the 365-Day Done Right Promise and photo proof of the finished attic
Laurel stays green all year, so should your home’s comfort. That’s the idea behind the name.
Which Owens Corning Products This Applies To
We work with the two Owens Corning lines that dominate Woodland Hills attics: ProPink fiberglass batts and rolls (R-13, R-19, R-30, and R-38) and the AttiCat blown-in fiberglass system. If your attic was built or retrofitted any time after the mid-1990s, there’s a strong chance one of these is already up there.
Here’s the compatibility detail most guides skip: Owens Corning batts come in specific widths, 15 inches or 23 inches, meant to friction-fit between standard joist and truss spacing. If a previous contractor crammed a 23-inch batt into 16-inch on-center framing, it’s compressed, and compressed fiberglass loses R-value fast. We see this constantly in Woodland Hills homes, especially the 1960s and 1970s ranch houses south of Ventura Boulevard where joist spacing drifts and previous installers cut corners.
For the AttiCat blown-in system, Owens Corning specs its own AttiCat machine to fluff the fiberglass to the right density. Run it through an older-generation blower at the wrong setting and you get settling within three years, plus all those little gaps that turn a “new” insulation job into a thermal leak. Chase Whitaker, our owner, is known for catching these install mistakes on inspection, especially around recessed light housings and plumbing chases that were never sealed before the insulation went down.
OEM vs aftermarket: When you ask for Owens Corning, we install Owens Corning. We also stock equivalents from Johns Manville, Knauf, CertainTeed, and GreenFiber for homeowners who want a spec-matched option at a different price point. But if the Owens Corning label matters to you, we won’t substitute without asking first and writing the exact product name on your quote.
Signs Your Owens Corning Attic Insulation Is Failing
- Upstairs rooms run 8 to 12 degrees warmer than downstairs. This is the classic symptom of under-insulated attics in Woodland Hills, where summer attic temps regularly hit 140°F and heat pushes straight through a thin insulation layer into the bedrooms below.
- Your insulation looks flat, patchy, or has gaps around the edges. Fiberglass batts settle and compress over time. Once you see bare sheetrock or joist tops showing through, the R-value has dropped well below what Owens Corning rated it for.
- Energy bills climb every summer while the thermostat stays the same. Heat gain through the ceiling is the single biggest driver of cooling cost in Woodland Hills homes. If your usage keeps creeping up, the insulation isn’t doing its job anymore.
- Rodent or pest activity in the attic. Rats and squirrels tunnel through fiberglass, crush it, and leave droppings throughout. The insulation doesn’t just lose R-value, it becomes a health concern and needs removal and replacement.
- Damp, musty attic smell or visible water staining on insulation. Once fiberglass gets wet from a roof leak or condensation, it mats down and loses thermal performance entirely. In Woodland Hills, we see this a lot after heavy winter rain events when roof flashing fails.
If your attic is under-insulated, your AC is just paying rent to the outside air.
Replacement Cost & What’s Included
For a typical 1,200 to 1,800 square foot Woodland Hills home, here’s what you’re looking at:
| Service | Typical Range | What It Includes |
|---|---|---|
| Blown-in AttiCat fiberglass to R-38 | $1,400 – $2,200 | Removal of failed material if needed, air-sealing penetrations, full attic coverage |
| ProPink batt replacement (R-30 or R-38) | $1,800 – $3,200 | Tear-out of old batts, install new Owens Corning batts, sealing around vents and chases |
| Full removal + new insulation + air sealing | $2,600 – $3,800 | Complete attic reset for pest damage, water damage, or code compliance |
What drives the price in Woodland Hills specifically: cathedral ceilings (more common in the hillside homes off Mulholland), how much old material we’re removing and hauling, attic access difficulty, and whether you need rodent remediation before we can safely install. We hand you a written price before any work starts. No door-step surprises.
Every job includes the 365-Day Done Right Promise in writing. If something isn’t right within a year, we come back and fix it, no charge. If our repair fails, the second visit is free, no argument.
DIY or Call Us?
You can absolutely check your attic yourself. Look for bare spots, compressed batts, and any visible gap between insulation and ceiling. Measure your current depth, fiberglass at R-38 should be roughly 12 to 14 inches deep. That’s a safe, useful inspection you can do in ten minutes.
Where DIY goes sideways is the install. Blown-in fiberglass requires a proper machine and respirator, and you’re working in a 130°F attic in Woodland Hills while stepping between joists over a ceiling. One wrong step through the sheetrock and you’ve added a drywall repair bill to your insulation project. Batts are more forgiving, but cutting around recessed lights, wiring, and plumbing without sealing those penetrations first just recreates the problem you’re trying to solve.

FAQs
Fiberglass insulation itself doesn’t expire, but in Woodland Hills conditions, we typically recommend re-evaluating your attic every 15 to 20 years. Compression, moisture, and pest damage degrade performance well before the material technically “fails.” Call (559) 295-5362 and we’ll help you figure out if yours has life left.
Yes, if only a section is damaged, say from a small roof leak or a single rodent entry point, we can patch and top off that area without pulling everything out. If more than about 30% of the attic is compromised, full replacement usually costs less per square foot than extensive piecemeal repair.
Most standard Woodland Hills homes are done in one day, typically four to six hours from arrival to final photo walkthrough. Larger attics, full tear-outs, or rodent remediation can stretch into a second day, and we’ll tell you that upfront in the written quote.
We stock ProPink batts in R-19, R-30, and R-38, plus AttiCat blown-in fiberglass, on our trucks. If you need a specific Owens Corning product we don’t have on hand, we can usually source it within 48 hours. For exact availability and a free quote, call (559) 295-5362.
