CertainTeed Blown-In Insulation in New Braunfels: What to Know First
We provide independent CertainTeed blown-in insulation service in New Braunfels, typically completing attic jobs in one day with a written price delivered before any work starts. Most CertainTeed blown-in cellulose or fiberglass top-ups in our market run between $1.40 and $2.10 per square foot depending on existing depth and access, with dense-pack wall jobs starting higher due to the prep work involved. This page is for homeowners who’ve found CertainTeed insulation in their attic, are seeing uneven temperatures or energy bills climbing, and want a contractor who will test the house before and after rather than just blow material and leave. Call (830) 243-6352 for a free estimate with a written scope.
How CertainTeed Products Fail - and How We Fix Them
- InsulSafe SP settling in vented attics. CertainTeed’s blown fiberglass InsulSafe SP can lose 10-15% of its labeled R-value within five years in New Braunfels homes where attic ventilation pulls humid Gulf air through the insulation layer. The fibers compress and the thermal barrier thins, especially near the eaves where wind washing is strongest. We remove the settled material, air-seal the deck and top plates first, then reinstall to a stable, higher density with documented depth markers.
- TrueComfort cellulose bridging over irregular joist bays. TrueComfort blown cellulose, when installed too quickly in older New Braunfels homes with mixed 2×4 and 2×6 framing, bridges across joist tops and leaves voids underneath. The homeowner feels cold spots on the ceiling below. We break up bridging with controlled hose work, use depth gauges in every bay, and verify with thermal imaging before we close the hatch.
- Optima dense-pack settling in balloon-framed walls. Optima, CertainTeed’s dense-pack cellulose product, can settle in the tall, unblocked stud cavities common in pre-1980 New Braunfels construction near the historic district. The gap forms at the top of the wall, creating a direct thermal bypass. We dense-pack to 3.5 pounds per cubic foot minimum, use inspection ports to verify fill, and won’t sign off until the wall cavity is confirmed full.
- MemBrain vapor retarder failure in humid attics. When CertainTeed’s MemBrain smart vapor retarder is installed over unsealed ceiling penetrations, attic moisture migrates through the leaks and condenses on the cool side of the retarder. The facing delaminates and the insulation beneath it mats. We find the leaks with a blower-door test, seal them with fire-rated foam and tape, then replace the damaged sections with properly detailed MemBrain or an alternative suited to the specific assembly.
- SpeedyBag system clogs with Gulf Coast moisture. CertainTeed’s SpeedyBag packaging, while convenient for the installer, can absorb enough humidity during a typical New Braunfels summer morning to cause clumping in the hopper. The clogs waste material and create inconsistent density. We stage bags inside the conditioned space before opening, monitor hopper moisture, and switch to loose-fill delivery from our truck-mounted system when conditions warrant.
Our CertainTeed Blown-In Insulation Process
- 1
Call and schedule. A live person answers, collects the basics, and books a diagnostic visit. We text when the technician is en route.
- 2
Blower-door test and attic inspection. We pressurize the house and measure CFM50, then photograph every penetration, top plate gap, and can light. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
- 3
Written price and scope. Before any work starts, you receive a flat price, a written scope of work, and our warranty terms. No work begins without your signature.
- 4
Air sealing first, then insulation. We seal all accessible leaks with fire-rated foam, tape, and gasketed covers. Only after the blower-door retest shows improvement do we begin blowing CertainTeed material.
- 5
Installation to spec. We install to the density and depth specified for the product, whether that’s TrueComfort at settled density, InsulSafe SP at full loft, or Optima at dense-pack pressure. Depth markers and thermal images document coverage.
- 6
Final blower-door test, photo record, and walkthrough. You receive printed pre- and post-job CFM50 readings, a photo record of the completed work, and our 365-Day Done Right Promise in writing.

Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for CertainTeed Work
We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of the attics we enter in New Braunfels already contain CertainTeed products. Wes Okafor and our crew know the difference between InsulSafe SP settling and a true installation error, and we won’t sell you new insulation until we’ve proven whether the old material failed or the air sealing was never done in the first place.
Our before-and-after blower-door numbers are printed and filed by address, which has helped more than one homeowner in the River Road corridor satisfy a buyer’s inspector during resale. We also work with Reflectix and other brands when a hybrid solution makes more sense than sticking with one manufacturer. Calls are answered by a live person 24/7. The 365-Day Done Right Promise applies to every completed job, backed by a written scope and warranty delivered before anyone lifts a tool.
FAQs
No. CertainTeed’s product warranties cover manufacturing defects and are not contingent on using a manufacturer-authorized installer for service or additions. We document the existing product line, lot numbers where visible, and our installation details so any future warranty claim has the paperwork it needs. Call (830) 243-6352 if you’d like us to review what’s in your attic.
Usually yes, though matching the exact vintage isn’t always necessary or desirable. We stock current InsulSafe SP, TrueComfort, and Optima products, and when we top up an existing layer we match the fiber type - fiberglass over fiberglass, cellulose over cellulose - to avoid compression or moisture-trapping issues. If your existing CertainTeed product has been discontinued, we’ll explain the compatible alternative in the written scope before you decide.
Repair, meaning breaking up settled areas and adding new material to reach target depth, typically costs 40-60% less than full removal and replacement. But repair only makes sense if the existing insulation is dry, uncontaminated, and the air sealing is already complete. We test for moisture and run the blower-door before recommending either path. Call (830) 243-6352 and we’ll show you what we found.
Most attic top-ups and air-sealing combos are completed in one day. Dense-pack wall work or full attic removals with old insulation extraction typically take two days. We schedule within a week of your approved written price, and we don’t book more than we can finish. Call (830) 243-6352 for current availability.
You get a printed blower-door report with pre- and post-job CFM50 readings, a photo record of the completed work, a copy of the signed written scope, and the 365-Day Done Right Promise warranty. We keep a duplicate file by address. When Wes Okafor started this practice, it was because he’d seen too many homeowners left with nothing but a receipt and a handshake. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
