Owens Corning Attic Insulation: The Long Beach Owner’s Guide
We stock and install Owens Corning blown-in fiberglass and batt insulation in Long Beach every week. A typical attic insulation job runs $1,800 to $3,400 depending on square footage, current R-value, and access. Most homeowners don’t know their insulation has failed until the upstairs rooms won’t hold temperature or the July AC bill jumps 40%. You feel it before you see it: the bedroom over the garage is ten degrees hotter than the rest of the house, the hallway ceiling feels warm at night, or you can stand in the kitchen and feel a draft from the attic hatch. When Owens Corning insulation was installed correctly, it lasts decades. When it gets compacted by foot traffic, soaked by a roof leak, or chewed through by Long Beach roof rats, it stops doing its job quietly and starts costing you money every single month.
Which Owens Corning Models This Applies To
Our crews in Long Beach work with the full Owens Corning residential attic lineup: ProPink blown-in fiberglass, AttiCat Expanding Blown-In Insulation, EcoTouch batts, and the PROPINK line in R-30, R-38, R-49, and R-60. Each has a different use. AttiCat is what we blow into open attics with uneven joist spacing; EcoTouch batts go into clean, standard-framed cavities. Here’s the compatibility gotcha most homeowners miss: blown-in fiberglass settles and loses R-value when humidity drives moisture into the attic, and Long Beach’s marine layer means attics here run wetter than inland. A bag rated R-30 at installation will not be R-30 five years later if the attic isn’t vented right. We check and bring the attic to current code. One checkable spec: Owens Corning’s own data shows blown-in fiberglass can lose 20% of its R-value when compressed or settled, which is why we measure depth, not assume. Alden Insulation Long Beach is an independent installer, not affiliated with Owens Corning, so we recommend the right Owens Corning product for your attic rather than pushing one line for its own sake.
Signs Your Owens Corning Attic Insulation Is Failing
- Upstairs rooms won’t match the thermostat. The AC runs constantly and the second floor still feels five to eight degrees warmer. Your insulation has settled below its rated depth or gotten compacted. The air gap at the top of the wall lets heat pour in through the ceiling.
- Your summer electric bill jumped without a rate change. Southern California Edison raised rates, yes, but a 30% jump month over month usually means the attic insulation stopped doing its job. Heat gain through the attic is the single biggest driver of cooling cost in Long Beach single-story ranches.
- Damp or musty smell near the attic hatch. Fiberglass doesn’t rot, but when roof leaks or bathroom fans vent into the attic instead of outside, moisture soaks the batts. Wet fiberglass loses R-value fast and holds that moisture against the ceiling drywall.
- Rodent trails, tunnels, or droppings in the insulation. Long Beach roof rats love fiberglass. They tunnel through it, compress it, and leave waste that makes the attic smell. Chewed-through insulation means the R-value is gone in those channels and needs full removal and replacement, not a patch.
- You can see the ceiling joists from inside the attic. If the joists are exposed, your insulation is at or below the top of the framing. That means you’re at R-11 or less in a city that calls for R-38 to R-49. You’re paying for heating and cooling that’s leaving through the roof.
Replacement Cost & What’s Included
In Long Beach, expect $1,800 to $3,400 for a full Owens Corning attic insulation replacement on a 1,200 to 1,800 square foot home. Smaller attics under 1,000 square feet with good access and no rodent damage run closer to $1,500. Larger homes, steep pitch, or attics needing complete removal of old, contaminated insulation push the number up. The price includes removal of failed or damaged material, air sealing around penetrations, new Owens Corning blown-in or batt insulation to the R-value the attic calls for, and full cleanup with a written price before we start. No numbers change at the door. The work is covered by our 365-Day Done Right Promise: if it fails within a year, we come back and make it right at no charge, in writing. Bryce Holloway built this company on exactly that point: you should never have to haggle for a contractor to honor their own work.
DIY or Call Us?
You can check your insulation depth yourself with a tape measure: less than 11 inches of fiberglass in a Long Beach attic means you’re under-insulated, full stop. You can also check for obvious signs: visible joists, damp spots, rodent trails. What you should not do is climb into a hot attic in July or crawl through fiberglass without a respirator and full sleeves. Blown-in fiberglass releases fine particles that irritate your lungs and skin. And removing contaminated insulation, the kind with rat droppings or wet matting, is a job for a crew with protective gear and a HEPA vacuum. If the inspection is simple, do it. If the fix involves removal, air sealing, or climbing around in 130-degree attic heat, call us at (562) 317-6204 and let a background-checked, uniformed crew handle it. We’ll give you the written price before a single tool comes off the truck.
FAQs
Owens Corning fiberglass doesn’t break down chemically, so the material itself lasts decades, but its performance in Long Beach attics usually degrades after 20 to 25 years due to settling, moisture from the marine layer, and rodent activity. Most attics we inspect need replacement not because the fiberglass failed but because it compacted below the recommended depth for R-38. Call (562) 317-6204 and we’ll measure your attic’s actual R-value in about 30 minutes.
In some cases, yes: if the issue is low depth with no water or rodent damage, blowing additional Owens Corning AttiCat on top brings the attic to the right R-value. But if the existing insulation is wet, compacted solid, or contaminated with droppings, the correct fix is full removal and fresh install. Patching over failed insulation earns you a higher electric bill, not a lower one.
A standard one-attic insulation removal and replacement in Long Beach takes four to six hours with a two-person crew. Larger attics, heavy contamination, or older homes with tight access can push it to a full day. The written quote includes a clean finish: no debris left in the attic, the hatch closed and sealed, and your driveway swept before we leave.
Yes. Our Long Beach crews carry Owens Corning AttiCat blown-in fiberglass, EcoTouch batts in the common R-values, and the equipment for air sealing in the same visit. We also stock Reflectix radiant barrier for attics where heat gain from the roof deck is the bigger issue. The truck leaves our yard loaded for the job, so there’s no second appointment to get materials.
