CertainTeed Attic Insulation: The Fort Worth Owner’s Guide
If you’re looking for CertainTeed attic insulation in Fort Worth, here’s the straight answer: we stock and install CertainTeed InsulSafe and TrueComfort blown-in fiberglass, and most attic jobs run $1,200 – $2,800 depending on square footage and the R-value you need. We can typically get a crew out same week, often same day if you call before noon. Most Fort Worth homeowners figure out their CertainTeed insulation has failed the hard way: the AC runs constantly in August, the upstairs bedrooms stay ten degrees hotter than the living room, or the electric bill jumps $80 a month with no other explanation. Sometimes it’s a roof leak that soaked a section of insulation and compressed it flat. Either way, the fix is usually a removal and re-blow, not a patch job.
Laurel Attic Insulation Fort Worth is an independent insulation contractor. We’re not affiliated with or sponsored by CertainTeed. We just work with their products because they hold up in Texas attics.
Which CertainTeed Models This Applies To
CertainTeed makes two blown-in fiberglass lines you’ll find in Fort Worth attics: InsulSafe and TrueComfort. InsulSafe is the premium line, rated for R-60 in attics and backed by CertainTeed’s 25-year “no shedding, no settling” warranty. TrueComfort is the mid-tier option, still solid, but rated for lower R-values on a per-inch basis. Here’s the compatibility gotcha most people miss: if your home was insulated before 2015, there’s a good chance it’s not actually CertainTeed. It’s often Owens Corning AttiCat or an older Johns Manville product, and mixing blown-in fiberglass brands in the same attic is fine as long as the R-value math works out. But if you’re topping off existing insulation and want to match the brand, you need to check the bag label or the attic card stapled near the hatch. No card? We’ll identify it during a free attic assessment.
We also keep quality aftermarket equivalents on the truck for jobs where matching CertainTeed exactly doesn’t matter for performance, and we stock Reflectix radiant barrier for Fort Worth attics that need a heat-reflective layer under the roof deck.
Signs Your CertainTeed Attic Insulation Is Failing
Insulation doesn’t fail with a bang. It fails quietly, and by the time you notice, you’ve been paying for it for months.
- Upstairs rooms won’t hold temperature. Your AC runs 20 minutes, shuts off, and ten minutes later it’s hot again. This usually means the insulation has settled below its rated R-value, or gaps have opened up around the attic perimeter. CertainTeed InsulSafe is warrantied against settling, but Texas attics with poor ventilation push even the best fiberglass past its limits.
- Your electric bill spiked in a mild month. Fort Worth summers are brutal, but a $400 July bill when you kept the thermostat at 78 usually points to insulation that’s failed or was never enough to begin with. We see R-19, or sometimes just R-11, in homes built before the 1990s. Code now calls for R-38 to R-60 in this climate zone.
- Cold spots on the ceiling in winter. If you can feel cold radiating through the drywall in January, the insulation directly above that spot is compressed, water-damaged, or missing. Fiberglass loses most of its R-value when compressed even half an inch.
- You can see the ceiling joists in your attic. Look up there with a flashlight. If the top of the joists is visible above the insulation line, you’re under-insulated. R-38 of blown fiberglass is roughly 10 to 14 inches deep, depending on the product.
- Evidence of rodents or a past roof leak. Rat tunnels through fiberglass and a single roof leak can turn a 15-square-foot section of CertainTeed into a matted, paper-thin mess. Both require removal and a fresh blow, not more insulation on top.
Replacement Cost & What’s Included
In Fort Worth, full attic insulation replacement with CertainTeed blown-in fiberglass typically runs $1,200 – $2,800 for a standard 1,200-to-2,000-square-foot attic. That includes removal of the old material, air sealing around penetrations, and blowing the new insulation to your target R-value, usually R-38 or R-49. A topper job with no removal runs $700 – $1,400. Here’s what drives the price:
- Access. A tight attic hatch in a ranch-style Fort Worth home is straightforward. A low-slope roof with a scuttle hole in a closet adds labor time.
- Depth of the old insulation. Removal of eight inches of compacted fiberglass takes longer than clearing three inches.
- Air sealing work. Gaps around can lights, bath fans, and top plates leak conditioned air into the attic. We seal them before blowing. Skipping this step is why some homeowners re-insulate and see only a small bill improvement.
Every job includes a written price before work starts, a 365-Day Done Right Promise in writing, and a free second visit if anything’s not right. No door-step surprises. That’s how we’ve run things since 2003.
DIY or Call Us?
You can absolutely check your insulation depth yourself. Grab a flashlight, open the hatch, and look. If the insulation is below the tops of the joists, or you see gaps and bare drywall, you’ve got your answer. What you shouldn’t DIY is removal and re-blow. Blown-in fiberglass is not dangerous to handle the way garage door springs are, but removal without the right equipment and dust control sends glass fibers through your house, and blowing insulation evenly to a specific R-value takes a machine, a second person, and a trained eye. Most Fort Worth homeowners who try it end up with inconsistent depth, clogged soffit vents, and insulation in places it shouldn’t be. We’ll assess your attic, show you the numbers, and give you a written price before any work begins. Call (817) 730-5474 and we’ll come out, no charge for the assessment.
FAQs
CertainTeed InsulSafe carries a 25-year warranty against settling and shedding, and in a properly ventilated Fort Worth attic it should perform well for two decades or more. But Texas heat and humidity, roof leaks, and rodent activity can shorten that lifespan considerably, especially in homes where the attic ventilation was never upgraded.
Yes, if the existing insulation is dry, uncontaminated, and not compressed. We blow new CertainTeed fiberglass directly on top to reach your target R-value. If the old material is water-damaged, moldy, or full of rodent droppings, it needs to come out first. Call us at (817) 730-5474 and we’ll tell you which situation you have, free.
Most Fort Worth attics take four to six hours from start to finish, including removal, air sealing, and the new blow. Larger homes or those needing extensive prep work can run a full day. We give you a live arrival time and before-and-after photos on every job, so you can see exactly what was done.
We stock CertainTeed InsulSafe and TrueComfort blown-in fiberglass on our trucks, plus Reflectix radiant barrier. On the rare occasion we need a specific CertainTeed product we don’t carry, we can usually have it within one to two business days through our Fort Worth suppliers.
