Our Attic Insulation Services in Selma

Blown-In Attic Insulation

Blown-In Insulation in Selma - loose-fill material blown through a hose to achieve uniform depth and coverage - is what we install most often. The 2000s-2010s production homes here were typically insulated with Owens Corning or Johns Manville blown-in fiberglass at or near minimum Texas code, R-30. After 15-25 years of Selma’s extreme heat cycling, that material has settled to 4-6 inches in most attics we’ve inspected, sometimes delivering an effective R-value in the teens. We blow new material to R-49 or above, per current IECC recommendations for our climate zone, and we never blow over an unsealed attic floor. Air sealing of top plates, can lights, and penetrations comes first - always.

Attic Batt Insulation

Batt insulation - pre-cut fiberglass or mineral wool panels - works well for Selma homes with open attic trusses and clear access, or for targeted repairs where blown-in would overfill a cavity. We stock Knauf and Rockwool batts for Selma jobs requiring specific dimensions or fire-rated assemblies near furnace flues or chimney penetrations. Batts are less common for full attic retrofits here because blown-in achieves more complete coverage around irregular framing and wiring, but we’ll specify batt when the job calls for it and explain why in your written scope.

Attic Insulation Top-Up

This is our most frequent Selma service call. The original insulation hasn’t failed catastrophically; it’s just settled and thinned to the point where your AC runs continuously from June through September. We inspect the existing material for moisture damage or rodent activity, seal attic bypasses, then blow new Owens Corning or Johns Manville fiberglass on top to restore depth and achieve R-49. A typical Selma top-up runs $1,800-$2,800 for a 2,000-square-foot home. We were called out to a 2006-built home in the Mesa Verde subdivision near the I-35/Loop 1604 interchange where the homeowner’s summer electric bills had climbed every year despite a newer AC unit. Our crew found the original builder-grade blown-in fiberglass had settled to roughly 4-5 inches - well below its original R-30 - and we topped it up with Owens Corning blown-in insulation to R-49 while sealing attic bypasses around can lights and the furnace flue. The homeowner reported noticeably shorter AC run times within the first cooling season.

Attic Insulation Replacement

When existing insulation is contaminated, water-damaged, or degraded by rodent activity, we strip it entirely and start fresh. Full replacement in Selma typically runs $3,200-$4,200 for a standard tract home, including removal, disposal, air sealing, and new R-49 blown-in material. We document the cavity condition with photos before and after - part of every job’s Documented Photo Record - so you see what was under the old stuff.

Attic Baffles & Ventilation Prep

Selma’s 150°F+ attic temperatures in July and August will cook any insulation that blocks soffit vents. We install baffles - vent chutes that maintain airflow from eave to ridge - before adding material over vented eaves. This is standard on our Attic Insulation jobs, not an upsell. Proper ventilation prep prevents moisture accumulation and preserves the effective R-value of your new insulation through decades of South Texas heat.

Common Attic Insulation Problems We See in Selma Homes

• Settled builder-grade R-30 fiberglass. The blown-in material installed in Selma’s 2000s-2010s tract homes has compressed and shifted after 15-25 years of extreme heat cycling. What read as adequate at your home inspection now delivers a fraction of its original performance.
• Attic temperatures exceeding 150°F. From June through September, Selma’s unventilated or poorly insulated attics become solar ovens. Without R-49+ insulation and proper air sealing, that radiant heat overwhelms your ceiling plane and forces your cooling system into near-continuous operation.
• Unsealed attic bypasses. Top plates, can lights, bath fan housings, and furnace flue penetrations leak conditioned air directly into the attic in most Selma homes we’ve tested. Blower-door readings before sealing routinely show 3,500-5,500 CFM50 in these houses; after sealing and insulation, we typically cut that by 30-50 percent.
• County-line permit confusion. Selma’s city limits straddle the Bexar-Guadalupe county line, meaning an attic insulation job on one side of the street may require a Guadalupe County permit while the other side goes through Bexar County - with different inspector contacts and processing timelines. Contractors must confirm which county a specific parcel falls in before pulling permits. We verify this in our initial site survey so your job doesn’t stall for paperwork.
