CertainTeed Blown In Insulation in Dallas: What to Know First
We install and service CertainTeed blown-in insulation throughout Dallas, and most jobs are done in a single day. Blown-in insulation means loose fiberglass or cellulose blown into your attic cavity under pressure, filling every gap and void that batts leave behind. We’re an independent CertainTeed service provider, not a factory-authorized dealer, which means we can tell you straight when CertainTeed is the right call and when another material would serve your house better.
This page is for Dallas homeowners who already have CertainTeed insulation or are weighing it against other brands. If you want a written price before anyone sets foot in your attic, call (361) 607-0906. A live person answers, day or night.
How CertainTeed Products Fail – and How We Fix Them
- CertainTeed InsulSafe SP settling after storm season. Dallas gets violent spring storms, and the humidity that follows compresses loose-fill fiberglass faster than people expect. InsulSafe SP is a solid product, but after five or six years in a Dallas attic, we regularly find it has settled 20 to 30 percent, leaving the top six inches of the attic cavity nearly empty. The fix is a density re-blow over the settled material, not a full removal. We map the existing depth, calculate the R-value loss, and top it off to restore the original spec.
- CertainTeed TrueComfort batts installed by a previous contractor, now leaving gaps. We see a lot of older Dallas homes where someone laid TrueComfort batts between joists but never addressed the perimeter gaps, soffit areas, or around recessed lights. The homeowner thinks they have insulation, but the thermal camera shows heat streaming through the edges. Our fix is blowing CertainTeed loose-fill into those voids on top of the batt layer, which seals the bypass points without pulling everything out.
- Air infiltration through the attic floor, not a product failure at all. CertainTeed fiberglass does exactly what it’s designed to do, but if the attic floor isn’t air-sealed first, even the best blown-in insulation underperforms. In older Dallas neighborhoods around Lakewood and East Dallas, we routinely find unsealed top plates, open wall cavities, and plumbing chases that dump conditioned air straight into the attic. We air-seal first, then blow over it. That’s the order that works.
- Rodent and pest damage in CertainTeed blown-in material. Squirrels and roof rats love tunneling through loose-fill insulation, and a Dallas attic is prime habitat. If you hear scratching overhead at night, the insulation has likely been matted down and contaminated in the nest areas. We remove the affected zones, treat the entry points, and re-blow with fresh CertainTeed material. Leaving contaminated insulation in place is a health issue, not just a comfort one.
- Undersized R-value from a builder-grade blow, especially in post-2010 construction. Many Dallas production builders in the 2010s installed the minimum code requirement, which at the time was R-30 for attics. CertainTeed material was often used, but the depth was inadequate for a Dallas summer. We routinely re-blow these attics to R-38 or R-49, which is the honest fix for a house that can’t keep up with August heat. The material was never the problem. The original depth was.
Our CertainTeed Blown In Insulation Process
- 1
You call, a person answers. We ask about square footage, the age of the house, and what you’ve noticed: hot rooms, high bills, noise. We book a time that works and send you the tech’s name and photo before we arrive.
- 2
We inspect the attic properly. Headlamp, respirator, thermal camera. We measure existing depth, check for air leaks, moisture, wiring issues, and any signs of pest activity. We look at the whole attic floor, not just the access point.
- 3
We give you a written price before work starts. No verbal estimate that inflates later. The price covers material, labor, cleanup, and the specific R-value we’re installing. You approve it or you don’t. No pressure.
- 4
We prep the attic. Air-sealing first where needed, baffles at the soffits to protect ventilation, and protective covers on recessed lights and bathroom fans where code requires it. Then we run the hose and start blowing.
- 5
We blow CertainTeed to the agreed depth. We use depth markers so you can see exactly what R-value was installed, and we check density as we go. A proper blown-in job has consistent coverage, not hills and valleys.
- 6
We walk you through it, then we hand you the written guarantee. Three hundred sixty-five days, in writing, covering labor and materials. If something isn’t right, we come back at no charge. That’s the whole promise.
What CertainTeed Blown In Insulation Costs in Dallas
For a typical 1,500 to 2,000 square foot Dallas home, blowing CertainTeed InsulSafe SP to R-38 from bare joists runs roughly $1,800 to $2,600. If your attic already has settled material and we’re topping it off to restore depth, expect $900 to $1,500. Full removal of contaminated or rodent-damaged insulation, plus re-blow, lands between $3,000 and $5,000 depending on attic access and how much has to come out. Older homes near White Rock Lake with low-pitch roofs and tight access points will sit at the higher end.
| Scenario | Price Range |
|---|---|
| Blown-in to R-38, bare joists, typical 1,500 – 2,000 sq ft | $1,800 – $2,600 |
| Top-off / density re-blow over settled insulation | $900 – $1,500 |
| Full removal of contaminated insulation + re-blow | $3,000 – $5,000 |
| Air-sealing before blow (typical attic) | $600 – $1,200 |
What moves the price: access, the depth you want, whether we’re hauling out old material, and whether air-sealing is needed first. Call (361) 607-0906 and we’ll give you a written quote based on your attic, not a spreadsheet guess.
Why Dallas Homeowners Call Aspen Attic Insulation Dallas for CertainTeed Work
Because we tell you who’s coming before they arrive. Every tech is background-checked, identity-verified, and shows up in a marked uniform with a photo ID badge. You get their name and picture before the visit. If the person at your door doesn’t match, the visit is free and we make it right. That’s the Threshold Standard we operate under, and we’ve held to it since 2002.
We also don’t push one brand. We stock materials from eight manufacturers, including CertainTeed and Reflectix, so if CertainTeed is genuinely the right product for your attic, that’s what goes in. If another material fits better, we’ll tell you and show you the price difference in writing. Garrett Sloane has been running insulation crews in Dallas long enough to know that quoting straight is faster for everyone. If your attic is working against you, your AC never had a chance.
FAQs
No. Blown-in insulation installed by any contractor does not void a product warranty on the insulation itself. CertainTeed warrants its loose-fill products against defects in manufacturing, not against installation. What matters is that the material is installed to the depth and density stated on the bag. We install to manufacturer spec and document the depth with photos before we leave.
Topping off is almost always cheaper, usually half to a third of the cost of full removal and replacement. The exception is when the existing material has been contaminated by rodents, water, or fire damage. In those cases, blowing new insulation over a problem just buries the problem. Call us and we’ll tell you which situation you have.
Most attics are done in a single day, from inspection to cleanup. Larger homes or jobs that require full removal of old material can take two days. We’ll give you a written schedule with your written price, so you know exactly when we’re coming and when we’ll be done.
Yes. Blown-in insulation work is contained to the attic and we run our hoses through a window or door with drop cloths in place. There’s some noise from the blower for a few hours, but the living space stays clean. If you have a child napping or a work call, let us know and we’ll work around it.
We do. Reflectix works as a radiant barrier under the roof deck, and it pairs well with blown-in CertainTeed on the attic floor. They do different jobs: Reflectix reflects radiant heat, CertainTeed traps conductive heat. In a Dallas attic, the combination can make a noticeable difference in upstairs bedroom temperatures during July and August.
