Call (737) 227-6219

We serve Kirby from our San Antonio dispatch office, and crews are usually on-site in Kirby within 45 minutes of the scheduled window. That matters here more than most places, because Kirby is a self-governing enclave entirely surrounded by San Antonio, and out-of-town insulation contractors routinely file permits with the wrong city hall. We’ve pulled permits through Kirby City Hall enough times to know the inspector’s schedule and the exact documentation they want to see first.

Why Topside Attic Insulation Canyon Lake Is Kirby’s Preferred Blown-In Insulation Company

Kirby homeowners research thoroughly before they call. They read three-star reviews as carefully as five-star ones, and they want documentation, not promises. We’ve sealed and insulated over 9,000 homes since 2016, and every job starts with a written price and ends with a Documented Photo Record. On air-sealing jobs, we publish before-and-after blower-door numbers so you can verify the result in a single figure.

Our Kirby customers specifically mention two things in reviews: the text they receive when their technician is en route, and the written scope they sign before anyone lifts a tool. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way. No voicemail loops, no callback windows measured in business days.

Response time to Kirby averages under an hour because we stage materials and crews for Bexar County work daily. We also know which Kirby neighborhoods sit on Blackland clay versus more stable soils, and that changes what we inspect before we quote.

Our Blown-In Insulation Services in Kirby

Blown-In Cellulose

We blow GreenFiber cellulose in most Kirby attics. Cellulose handles the 145°F summer attic temperatures better than older fiberglass products, and it packs well into the shallow cavities common in Kirby’s low-pitch GI Bill-era roofs. A typical Kirby attic cellulose job runs $2,200-$3,800 for full remediation, or $1,800-$2,800 for a top-up over existing batts. We seal top plates, can lights, and penetrations first. Always. Blowing insulation over an unsealed attic floor is something we don’t do.

Blown-In Fiberglass

Knauf and Owens Corning loose-fill fiberglass works well in Kirby homes where moisture management is already solid and the homeowner wants a lighter material that won’t settle as aggressively over decades. We see this choice most often in slab-on-grade homes near FM 78, where there’s no crawlspace to complicate the envelope picture. Full fiberglass remediation in Kirby typically runs $2,400-$4,000. We still air-seal first. The Haven Standard doesn’t change because the material does.

Dense-Pack Wall Insulation

Kirby’s 1950s-1960s tract homes were built with empty wall cavities or thin batts that have slipped and compressed. Dense-packing cellulose into those walls from the exterior or interior is often the only way to hit R-13 or R-15 in the walls without tearing out drywall. This is labor-intensive work, and in Kirby it typically runs $3,500-$5,500 for a full home depending on cavity count and access. We dense-packed the walls on that 1962 pier-and-beam home off Old Seguin Road after Blackland-clay foundation movement had shifted floor batts open under the house. The attic’s original R-8 fiberglass was no longer the whole story. After pulling the Kirby city permit, we dense-packed the wall cavities, blew GreenFiber cellulose over the existing joists to top out the attic, and reset the displaced under-floor batts before adding a radiant barrier to cut the 145°F summer attic load. The homeowner’s HVAC runtime dropped enough that the system stopped short-cycling by late afternoon.

Blown-In Top-Up

Not every Kirby attic needs full removal. If your existing batts are intact but compressed, a blown-in top-up of cellulose or fiberglass can bridge the gap to R-38 for $1,800-$2,800. We inspect first. If the original insulation is degraded, water-stained, or rodent-compromised, we’ll tell you and quote removal plus replacement. No top-up goes in without a written scope that says exactly what we’re adding and what the finished depth will be.

Trusted Brands We Service in Kirby

We source materials from Owens Corning, Johns Manville, Knauf, and others. No proprietary lock-in means we specify what performs for your specific envelope, not what moves a particular product line. For Kirby’s climate zone, that usually means GreenFiber cellulose or Knauf fiberglass for attic work, with Rockwool reserved for specific fire-blocking or sound-dampening applications. We stock common densities and blower configurations locally, so most Kirby jobs don’t wait on material delivery.

Common Blown-In Insulation Problems We See in Kirby Homes

• Baked-out original batts. Kirby’s 1950s-1960s attics have held R-7 to R-11 fiberglass at 140-160°F for sixty-plus years. The material has compressed and lost loft until it’s thin enough that heat pours straight through to the ceiling. Homeowners feel it as “the AC can’t keep up after 2 PM.”
• Blackland clay foundation gaps. Bexar County’s expansive black-clay soils cause chronic foundation movement in Kirby’s pier-and-beam homes. Seasonal shifting opens gaps between under-floor batts, creating slow air infiltration that homeowners blame on the HVAC. A crawlspace inspection almost always reveals displaced floor insulation.
• Shallow cavities, poorly sealed. Low-pitch roofs and shallow attic cavities leave little clearance. Crews that skip dense-packing wall cavities or don’t seal pipe chases leave air-infiltration paths that defeat whatever blown-in layer they add.
• Post-Uri cold-weather exposure. The February 2021 Winter Storm Uri froze unprotected pipe chases in under-insulated Kirby attics. We’re still doing whole-home assessments for homeowners who realized their envelope failed when it mattered most.
