How Owens Corning Products Fail - and How We Fix Them

Owens Corning makes solid insulation products. But nothing lasts forever, especially in Mission Viejo attics where summer heat pushes 140 degrees and winter nights drop into the 40s. Here’s what we actually see on service calls:

• Atticat blown-in fiberglass settling below code depth. Owens Corning AttiCat fiberglass can settle up to 20% over a decade, especially in Mission Viejo homes where attic ventilation pulls air through the loose fill. We see attics in the Aegean Hills area that measured R-30 when installed and now test at R-19. We top up with fresh AttiCat to restore R-38, which is the current California Title 24 minimum for attics.
• ProPink blown-in fiberglass clumping from moisture. In homes near Lake Mission Viejo, we regularly find Owens Corning ProPink blown-in fiberglass that’s matted and clumped because bathroom exhaust fans vent into the attic instead of outside. Wet insulation loses most of its thermal value. We find and fix the moisture source first, then remove the compromised material and blow in fresh insulation. If we don’t fix the moisture problem, we’re just renting you a temporary attic.
• Old batt insulation left in place under new blown-in. This is a Mission Viejo classic in homes built before 1990. Someone blew Owens Corning loose-fill right over old compressed fiberglass batts. The batts trap air pockets, the loose fill settles unevenly, and you end up with cold spots over the bedrooms. We remove the old batts and do a clean blow, which gets you consistent coverage and an honest R-value.
• AttiCat installation done without air sealing. Blown-in fiberglass filters air, but it doesn’t stop it. In Mission Viejo homes near the 5 freeway corridor, we see attics where Owens Corning AttiCat was installed years ago with no air sealing at can lights, top plates, or the attic hatch. Heated air still leaks out, dust from the attic still gets in, and the homeowner thinks the insulation failed. It didn’t. The prep was skipped. We air seal before we blow, every single time.
• Owens Corning blown-in cellulose in older Mission Viejo attics. Some older Mission Viejo homes have Owens Corning cellulose from the 90s or early 2000s. Over time, cellulose absorbs humidity and compacts, dropping from R-38 to something closer to R-22. Worse, we sometimes find it’s hiding rodent activity or old electrical issues. We remove it, inspect what’s underneath, and blow in fresh material rated for today’s climate.

Our Owens Corning Blown-In Insulation Process

Every Owens Corning insulation job in Mission Viejo follows the same six steps. We don’t send a salesperson to your house. We send someone who actually does the work.

1. 1
   Call and talk to a real person. You call (949) 528-8707, a live person answers, and we schedule a visit that fits your day. No call centers, no “we’ll get back to you within 48 hours.”
2. 2
   Attic inspection. We get into the attic and measure current depth, check for moisture, animal activity, air leaks, and electrical issues. This is where we find out if you need a top-up or a full removal and re-blow.
3. 3
   Straightforward pricing. We give you one written number that covers prep, material, installation, and cleanup. No surprise add-ons when the crew shows up. We’ll also give you a free second opinion on any competitor’s written estimate.
4. 4
   Prep work. We seal air leaks around recessed lights, top plates, plumbing penetrations, and the attic hatch. We address any moisture issues. We protect your floors and furniture from the work area.
5. 5
   The blow. We install Owens Corning blown-in insulation to the R-value your home needs, whether that’s AttiCat fiberglass for a standard attic or a dense-pack application for enclosed cavities. We measure as we go so you’re not guessing how much depth you got.
6. 6
   Cleanup and a final look. We vacuum up stray material, put things back where we found them, and walk you through what we did. Then we stand behind it. Every job is covered by the Done Right Promise: if it’s not done right, we make it right. Lifetime. No fine print.

And if we get up there and find that your Owens Corning insulation is actually fine, we’ll tell you that too. Walt Brenner has always had a rule: if you don’t need the work, we don’t sell it.
