This page is for Thousand Oaks homeowners who want to know exactly what goes into an Owens Corning blown in insulation job, what it costs here, and who’s showing up to do the work.

How Owens Corning Products Fail – and How We Fix Them

Owens Corning makes solid insulation, but nothing lasts forever in a Thousand Oaks attic. Here’s what we see on service calls across the Conejo Valley.

• Pink fiberglass batts compressing to half their rated R-value. The Owens Corning R-30 batts you may have in your attic lose loft after years of heat cycling between the Thousand Oaks summer sun and cool marine-layer nights. Compressed insulation insulates less, plain and simple. We blow Owens Corning AttiCat fiberglass over the top to restore the full R-value without tearing out the old batts.
• Settled blown in fiberglass from older installs. If a previous contractor blew in Owens Corning insulation below the recommended depth, it settles into low pockets that leave bare spots near the eaves. In Thousand Oaks ranch homes near the Conejo Valley Botanic Garden, we regularly find attics with 8 to 10 inches where code calls for 14. We top it off and level it out.
• Attic air leaks negating the insulation entirely. Owens Corning insulation only works if the attic is sealed. In homes off Lynn Road and Westlake Boulevard, we find recessed light housings, bathroom fan vents, and plumbing chases that let conditioned air pour into the attic. The insulation isn’t failing, the envelope is. We seal the bypasses before we blow in new insulation, because blowing fiberglass over a leak just hides it.
• Moisture damage from a poorly vented attic. Owens Corning fiberglass loses thermal performance when it gets damp, and Thousand Oaks’ marine layer can keep attics humid for weeks at a time in June and July. If your blown in insulation feels matted or your attic smells musty, the venting needs attention before new insulation goes in. We check soffit and ridge vents on every job before we blow a single bag.
• Pest activity in existing Owens Corning insulation. Rodents tunnel through fiberglass and leave droppings, but honestly, we see less of that in Thousand Oaks than in the Valley. What we do see more of is roof rat nesting near the foothills, especially in homes near Wildwood Park. We inspect for contamination and recommend removal in affected zones before blowing in fresh Owens Corning insulation, because you don’t want to trap that mess under a new layer.

Our Owens Corning Blown In Insulation Process

Here’s exactly how a blown in insulation job goes with us, from the first call to the final walkthrough.

1. 1
   You call (805) 309-1610. A live person answers, any time, any day. You tell us what you’re dealing with, and we schedule a visit. Before the appointment, you get the technician’s name and photo so you know who’s walking up your driveway.
2. 2
   The technician arrives and shows ID. Background-checked, uniformed, and photo-badged. Every time, no exceptions. That’s the Threshold Standard we operate under.
3. 3
   We measure and inspect. We measure square footage, check current insulation depth, look at venting, and identify air leaks. We also check for any wiring issues or old knob-and-tube that changes the approach.
4. 4
   You get a written price. Before we touch anything, you see exactly what the job costs. The full number, in writing. No “we’ll see how it goes” and no surprise line items at the end.
5. 5
   We blow in the Owens Corning AttiCat fiberglass. We use a calibrated machine and track bag count so you get the R-value you paid for, not an estimate. We install rulers in the attic so you can see the depth yourself.
6. 6
   Cleanup and a 365-day guarantee. We leave the work area clean, walk you through what was done, and hand you the written 365-Day Done Right Promise. If any repair fails within that year, the second visit is free.
