How CertainTeed Products Fail - and How We Fix Them

CertainTeed makes solid insulation products. But every material has weak points, and after 25 years in Fullerton attics we’ve seen exactly where CertainTeed blown-in products lose performance. Here’s what actually happens, and what we do about it:

• CertainTeed InsulSafe® fiberglass settles more than the bag suggests in vented Fullerton attics. InsulSafe is a great loose-fill fiberglass, but Fullerton’s dry heat cycles cause it to compact faster than you’d expect, especially in older homes where the original install was light. We regularly find R-38 attics that have settled to R-25 or worse within a decade. Our fix is a measured top-up with InsulSafe to true depth, not a guess based on bag count.
• CertainTeed TrueComfort® cellulose loses its fire-retardant treatment over time in high-heat attics. TrueComfort is a borate-treated cellulose, and the treatment does degrade under sustained attic temperatures above 130°F, which Fullerton attics hit regularly from June through September. When we pull samples and the treatment is spent, we don’t just top it up. We remove the compromised material and blow in fresh product so your home isn’t sitting with insulation that isn’t doing its full fire-safety job.
• Dense-pack CertainTeed fiberglass around can lights creates hot spots when the original installer skipped baffles. We see this in Fullerton’s older ranch-style homes near the Arboretum. The insulation gets packed tight against non-IC-rated fixtures, which is a fire hazard and kills airflow. We pull the material back, install proper baffles, and re-blow at the right density. It’s a detail a lot of crews miss.
• CertainTeed Optima® blow-in-blanket systems sag in the wall cavities of homes built in the 1990s and early 2000s. Optima is a hybrid system that works well when installed perfectly, but Fullerton homes built during that era often have improper netting tension. The result is voids at the top of wall cavities that no one sees until the drywall comes off. When we do dense-pack or retrofit work on those homes, we inspect for sag and correct the density before it becomes an energy bill problem.
• Blown-in CertainTeed fiberglass over old rodent-damaged material masks the damage until it’s a health issue. Fullerton’s older neighborhoods, especially around downtown and the neighborhoods east of Harbor Boulevard, have attics with decades of rodent activity. Blowing fresh CertainTeed material over contaminated insulation doesn’t fix the problem. We offer attic cleaning and rodent proofing before new insulation so you’re not paying to insulate a problem.

Our CertainTeed Blown-In Insulation Process

Here’s what a CertainTeed blown-in job looks like when you call Walt’s Insulation. No mystery, no surprises.

1. 1
   The call. You reach a live person at (657) 216-9948, day or night. Walt Brenner or one of our senior techs asks about your home, square footage, and what’s going on with your comfort and bills.
2. 2
   Free inspection. We come out, go into the attic, and measure actual depth, check for air leaks, look for rodent damage, and assess whether your existing CertainTeed material is still doing its job. You get a written assessment and a firm quote before any work is scheduled.
3. 3
   Prep and air sealing. We air seal can light gaps, top plates, and plumbing penetrations before blowing anything. Insulation only works if air isn’t moving through it.
4. 4
   The blow. We run the CertainTeed material through calibrated hoses at the manufacturer’s specified depth and density. For top-ups, we blow to R-38 or R-49 depending on your home and budget. For full installs, we remove old material when needed and start clean.
5. 5
   Verification. We show you the before-and-after depth readings, check for even coverage across all corners, and make sure the baffles are clear. Your attic gets photographed and documented.
6. 6
   The guarantee. Every job is covered by our Done Right Promise for life. If the insulation settles or the job isn’t right, we come back and fix it. No runaround, no expiration.
