Insulation Company in Round Rock, TX
Insulation in Round Rock has to work against two extremes: attic temperatures that climb past 150°F in July and surprise freezes in January that send cold air through every unsealed gap. Most homes here were built fast between the 1980s and 2000s, and many carry only 6 to 8 inches of settled fiberglass where today’s standards call for R-38 to R-60. That gap shows up as uneven room temperatures, high summer cooling bills, and cold spots in winter. We address it with upgrades matched to your home’s actual construction, not a generic one-size-fits-all approach. Call us at (325) 246-2929 for a written, no-surprise price before any work starts.
Why Round Rock Homes Are Different
Round Rock’s housing stock grew in waves: ranch-style homes from the 1980s, production subdivisions from the 1990s and 2000s, and a smaller number of newer custom builds. The 1990s and 2000s boom is where we see the most consistent problem. Builders in that era insulated to the 1993 energy code, which called for far less attic coverage than today’s recommendations. In neighborhoods like Forest Creek and Stone Canyon, we regularly find fiberglass batts that were installed around trusses and left with gaps at the edges, or blown-in insulation that has settled to a third of its original depth.
High ceilings and west-facing windows make the problem worse. A two-story entry or a family room with vaulted ceilings pulls heat upward all summer, and by late afternoon the west sun has been driving heat into the attic for hours before the air conditioner gets a break. The result is a thermostat that runs constantly while upstairs bedrooms stay five to eight degrees warmer than the rest of the house. Those are exactly the homes where air sealing plus a proper insulation upgrade produces a change you can feel in a single season. Garrett Sloane and our techs have walked enough Round Rock attics to know what the original installers left behind and what needs to be done now.
Our Main Round Rock Services
Round Rock homeowners most often call us for two things: bringing an under-insulated attic up to current standards, and sealing gaps that let conditioned air leak out. Each of the three services below has its own dedicated Round Rock page with full pricing, process details, and local specifics.
Attic Insulation in Round Rock
Most Round Rock attics need more than a top-up. The original install from the 1990s or 2000s usually has gaps at the eaves, settling in the center, and no air sealing around can lights, plumbing penetrations, or the attic hatch. Our approach starts with finding those leaks and addressing them, then bringing the insulation depth up to R-38 or better. In a two-story home with west-facing windows, this alone can level out the temperature difference between floors. The work is covered by our 365-Day Done Right Promise in writing. See full details on our Attic Insulation in Round Rock page.
Spray Foam Insulation in Round Rock
Round Rock’s humid summers push moisture into attics and wall cavities, which is why some homeowners choose closed-cell or open-cell spray foam. It creates an air barrier at the roofline, so the attic stops acting like an oven radiating heat into your ceilings. It also resists the moisture transfer that can lead to condensation problems during winter cold snaps. If the home has a vented attic with older batt insulation, spray foam is a different approach, not always a direct replacement, and we’ll explain which makes sense for your specific roof and HVAC setup. Pricing and a full breakdown live on the Spray Foam Insulation in Round Rock page.
Blown In Insulation in Round Rock
Blown-in insulation, loose fibers blown into the attic cavity to fill every gap, is one of the most common upgrades we do in Round Rock’s production-built homes. It layers over existing settled fiberglass and fills the spaces that batts could never reach. In a ventilated attic with a standard truss roof, we can often complete the job in a single day and you will notice the difference the first hot afternoon. The material choice matters here: humidity and roof heat cycle through the attic daily, so we match product to the specific attic rather than using whatever is on the truck. Learn more about costs and process on the Blown In Insulation in Round Rock page.

Brands We Service in Round Rock
We work with insulation from Owens Corning, Johns Manville, and Demilec, among others, because different attics need different materials. A vented attic over a 1990s ranch gets one product; a tight attic space on a newer two-story gets another. We stock the common options locally and can get specialty material to your Round Rock job quickly. Learn more on our brands page.

What pushes the price up in Round Rock: attic access through a small closet hatch, old wiring that needs to be worked around, and dense blown-in material that has to be removed before new insulation goes in. The written quote you receive upfront accounts for all of those conditions, so there are no post-job surprises. The 365-Day Done Right Promise covers labor and materials for a full year in writing, with a free second visit if the repair fails.
