Call (737) 252-7159 for a written price before any work starts.

We’ve insulated attics in Oak Creek, Old Round Rock, and across the Dell-boom subdivisions east of I-35. The tract homes built between 1993 and 2015 - Behrens Ranch, Eagle Ridge, Chandler Crossing - share a common problem: original insulation installed to minimum code that has degraded through two decades of Central Texas heat cycles. We know what we’ll find before we pull down the attic ladder.

Why Topside Attic Insulation Leander Is Round Rock’s Preferred Attic Insulation Company

Our reputation in Round Rock is built on documentation, not promises. We’ve completed attic insulation and air-sealing work in ZIP codes 78660, 78664, 78665, and 78681, and our Round Rock customers receive before-and-after blower-door numbers on every applicable job - a pressurization reading that shows, in one figure, how much conditioned air the home was losing before and after the work.

Response time to Round Rock is typically same-day or next-day. Our dispatch operates from the Austin office, but crews are routed locally and carry Owens Corning, GreenFiber, and Icynene materials on the truck. That matters for acreage properties around Indian Ridge or Behrens Ranch where a detached workshop insulation job can’t wait on a second delivery.

Round Rock homeowners read reviews carefully. We get that. Our three-star reviews are public, and we respond to every one. The pattern we see: customers who value the written scope, the photo documentation, and the 365-Day Done Right Promise. Under Haven Standard: Have it in writing. Every job gets one.

Blown-In Attic Insulation

Blown-In Insulation - Round Rock - loose-fill fiberglass or cellulose blown through a hose to fill irregular joist cavities - is what most Round Rock homes need. The Dell-boom tract homes in Fern Bluff and Lake Forest were built with R-30 fiberglass batts that have compressed to R-11 or lower under years of 150°F+ attic temperatures. We remove or cap the degraded material and blow high-density Owens Corning or GreenFiber to R-49, the current IECC standard for this climate zone. For west-facing rooflines in ZIP 78664 and 78665, we pair this with radiant barrier installation in the same visit.

Blown-In Attic Insulation

Attic Batt Insulation

Batt insulation - pre-cut fiberglass or mineral wool panels - still has a place in Round Rock, particularly in new additions, knee-wall spaces, or outbuildings with regular joist spacing. We stock Johns Manville and Owens Corning batts and install them after air sealing of top plates and penetrations is complete. We don’t blow insulation over an unsealed attic floor. Sealed first, then insulated. In that order.

Attic Insulation Top-Up

The top-up is our most common Round Rock service. Homeowners in Cimarron and Eagle Ridge call when their August electric bill spikes or the upstairs bedrooms won’t cool below 78°F. We assess what’s there, measure settled depth, and calculate the gap to R-49. Most top-ups run $1,800-$3,200 for a 2,000-square-foot footprint. We recently topped up a 2004 tract home in Chandler Crossing where the original R-30 fiberglass had settled to about R-11 and the west-facing attic hit 158°F by mid-afternoon. Our crew installed high-density blown-in Owens Corning insulation to R-49 and added a radiant barrier to the west roof deck in one trip. The homeowner’s August electric bill dropped noticeably, and the attic stayed cool enough to store holiday decorations without melting the plastic bins.

Attic Insulation Replacement

Full replacement is necessary when existing insulation is contaminated, water-damaged, or so degraded that topping up is throwing good material after bad. In Round Rock Glen and older sections of Old Round Rock, we’ve pulled out insulation compromised by roof leaks, rodent activity, or decades of dust loading. Replacement includes removal, disposal, air sealing, and new installation to R-49 with a documented photo record at each stage. Typical range: $3,200-$5,800.

Attic Insulation Replacement

Attic Baffles & Ventilation Prep

Attic baffles - cardboard or foam channels that maintain airflow from soffit vents up the roof deck - are critical in Round Rock’s low-pitched ranch and two-story designs. Without them, blown-in insulation blocks soffit intake and creates moisture traps. We install baffles at every soffit bay before insulating, ensuring the ventilation path is preserved. This is standard on every blown-in job, not an add-on.

Common Attic Insulation Problems We See in Round Rock Homes

Professional cutting pink fiberglass attic insulation with utility knife and guide
Common Attic Insulation Problems We See in Round Rock Homes
  • Compressed builder-grade batts in 1990s-2000s tract homes. In Eagle Ridge and Cimarron, the original fiberglass batts have compressed under 150°F+ attic heat, creating convective loops that let summer heat radiate straight into living spaces. The insulation is still there. It just doesn’t work anymore.
  • Missing radiant barriers on west-facing rooflines. In ZIP 78664 and 78665, builders commonly skipped radiant barriers to hit price points. Attics in Fern Bluff and Lake Forest routinely exceed 155°F, cooking HVAC ducts and forcing the system to run longer than it should.
  • Detached workshops with no thermal envelope. Acreage properties in Indian Ridge and Behrens Ranch often have outbuildings where insulation was never considered. These structures become unusable in summer and freeze-risk points in winter.
  • Attic ventilation choked by added insulation. Well-meaning homeowners or prior contractors blew insulation without baffles, blocking soffit intake. Moisture builds. Roof deck life shortens. We see this in older Round Rock Glen ranches where the attic was “improved” without understanding the airflow.

What Round Rock Customers Say

Trusted by homeowners across Round Rock and surrounding areas.

★★★★★

"Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."

Clifford E. · Verified customer
★★★★★

"The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."

Genevieve R. · Verified customer
★★★★★

"Crawl space encapsulation done properly. Photographs of the vapour barrier at every seam, and the damp smell in the hallway is gone."
