How Owens Corning Products Fail - and How We Fix Them

Owens Corning makes dependable insulation, but every product has its weak spots. Here’s what we see across Inglewood attics, crawl spaces, and rim joists:

• Foamular XPS boards delaminating at seams near the roof deck. In Inglewood’s marine-layer dampness, exterior-facing rigid foam that wasn’t taped and sealed properly starts pulling apart within four to six years. We remove the failing section, re-cut the seam, and seal it with closed-cell spray foam before re-flashing. The fix outlasts the original installation because the foam bonds where tape alone couldn’t.
• AttiCat blown-in fiberglass settling next to open-cell spray foam. We regularly open up attics where someone combined Owens Corning AttiCat blown-in with a partial spray foam job. The blown-in material settles up to 30% over five years, especially near bathroom vents, leaving the spray foam doing all the work. We remove the settled material, verify the foam thickness, and re-insulate to an even R-value across the whole surface.
• Unfaced EcoTouch batts going limp in damp crawl spaces. EcoTouch fiberglass batts lose their loft when Inglewood humidity works its way into a vented crawl space. Homeowners complain floors feel cold and musty. We pull the tired batts, address the moisture path with vapor barrier or closed-cell spray foam on the rim joist, and re-insulate. The difference in floor temperature is noticeable the same week.
• Thermafiber mineral wool sagging behind stucco walls. On older Inglewood homes, Thermafiber UltraBatt installed behind original stucco sometimes sags away from the framing after decades of settling. That creates a thermal gap you can feel from inside at the wall’s top plate. We inject open-cell spray foam into the void from the attic side. It expands to fill the gap without tearing out your stucco.
• Spray foam shrinkage around electrical boxes and plumbing penetrations. We’ve traced enough air leaks in SoFi-adjacent neighborhoods to know this one well: even properly installed spray foam can gap around boxes and pipes after the house moves through a few hot, dry summers. Our techs re-seal every penetration with a low-expansion foam, then verify the fix with a blower-door test. A 1/8-inch gap around an electrical box can move more air than you’d believe.

Our Owens Corning Spray Foam Insulation Process

Here’s what a typical Owens Corning spray foam job looks like when you call Warmline, from first phone call to final cleanup:

1. 1
   You call (424) 622-5846. A live person answers, no voicemail tree. We ask about your symptoms: hot rooms, cold floors, high bills, damp smells. We’ll tell you over the phone whether spray foam is even the right tool for your situation.
2. 2
   A technician comes out and looks. We don’t quote over the phone. We need to see your attic, rim joist, or crawl space. Expect a diagnostic walkthrough, not a sales pitch. Our techs are background-checked, uniformed, and they don’t recommend work your house doesn’t need.
3. 3
   You get a written, itemized estimate. We use Owens Corning product lines where they serve the job, and we’ll tell you if an off-brand alternative does the same thing for less. No scare tactics, no mystery surcharges at the end.
4. 4
   We do the work in one visit. Prep includes masking and covering your floors and belongings. We spray to the exact thickness the project requires, not “close enough.” Then we trim, clean, and inspect every inch.
5. 5
   We test, you feel the difference. If the job warrants it, we run a blower-door test before and after. You’ll see the air-leakage number drop on paper, and you’ll feel it inside the house that same night.
6. 6
   We hand you a written guarantee. Our 90-Day Done Right Promise covers the work. If it’s not right, we make it right. Period.

What Owens Corning Spray Foam Insulation Costs in Inglewood

Straight numbers, because you deserve them:

• Rim joist spray foam in a typical 1,200 sq ft Inglewood home: $1,400 to $3,200
• Open-cell spray foam in an attic (R-38, roughly 10.5 inches): $2,800 to $5,400 depending on square footage and access
• Closed-cell spray foam on a roof deck (R-21, roughly 3 inches): $4,200 to $8,600, with steep-roof or low-clearance work at the higher end
• Garage ceiling spray foam above a finished living space: $1,100 to $2,700

What moves the price: access (crawl spaces and low attics add labor), total square footage, existing insulation removal, and whether we’re sealing ductwork at the same time. You’ll get a fixed, line-item price before we start, and most jobs wrap the same day. Call (424) 622-5846 for a free estimate, and ask about the $50 Off Any Repair Over $250 credit if you’re also fixing an air-sealing issue.
