Fast, Reliable Attic Insulation Across Selma
Attic insulation in Selma typically runs $1,800-$4,200 for most homes, with same-day assessments available and crews dispatched from our San Antonio office. If your home was built during Selma’s 1990s-2010s development wave along Loop 1604 and I-35, there’s a strong chance your original blown-in insulation has settled to a fraction of its labeled R-value after decades of extreme attic heat cycling.
We’re familiar with the tract-home neighborhoods that define Selma’s residential map - from the early builds near Evans Road to the later phases around Retama Parkway and the Forum shopping corridor. Our Attic Insulation crews work these attics regularly. Call (830) 402-5240 to schedule a free assessment with a written price before any work starts.
Why Topside Attic Insulation Schertz Is Selma’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a significant portion of that work has been in the San Antonio metro’s northeast corridor - including Selma’s brick-veneer tracts, Cibolo’s newer subdivisions, and the mixed-era housing in Schertz. Our reviews from Selma customers consistently mention two things: the blower-door numbers we leave behind, and the fact that we air-seal before we insulate, not after.
Response time to Selma is typically same-day or next-day for assessments, with crews already routing through the Loop 1604/I-35 corridor for jobs in this cluster of cities. When you call (830) 402-5240, a live person answers - no voicemail loops, no callback windows measured in business days.
Our local knowledge matters because Selma’s housing stock is unusually uniform in its problems. The pre-IECC 2009 code minimums that governed original construction here created a predictable failure pattern: settled blown fiberglass, unsealed top plates, and soffit vents choked by decades of well-meaning but poorly executed top-offs. We don’t guess at what’s in your attic. We inspect, photograph, test, and write it down.
Our Attic Insulation Services in Selma
Blown-In Attic Insulation
Blown-in fiberglass or cellulose is the right fit for most Selma attics - especially the vented, truss-framed spaces common in 1990s-2000s tract construction. We source Owens Corning and GreenFiber products, measured and installed to target depth with marked rulers visible across the attic floor. A typical full-coverage blown-in job in a 1,800-2,400 square foot Selma home runs $2,400-$3,800, including prep and baffle installation at the soffits.
Attic Batt Insulation
Batt insulation has a narrower application in Selma’s housing stock, but it’s the right choice for certain knee-wall spaces, attic storage platforms, and the occasional cathedral ceiling found in bonus-room additions off Evans Road and Retama Parkway builds. We use Johns Manville batts cut to fit - not compressed into gaps, which destroys the R-value you paid for. Batt-only jobs in Selma typically fall between $1,800-$2,800.
Attic Insulation Top-Up
This is the defining job in Selma. Because the vast majority of local homes were built to pre-IECC 2009 minimum insulation standards, original blown-in has settled and compressed after 25-plus years of attic temperatures that routinely exceed 140°F. A typical Selma attic top-off - air-sealing first, then adding blown fiberglass to restore target R-value - runs $1,800-$3,200 for most homes in the 1,600-2,500 square foot range.
We pulled a job off a 1998 brick-veneer tract home near the Loop 1604/I-35 interchange where the original blown fiberglass had settled to roughly a third of its labeled depth, leaving the ceiling plane at bare drywall in spots near the attic access. Our tech ran a blower-door-guided air-seal on the top plates and can lights first, then topped up with Owens Corning blown fiberglass to restore the target R-value and added attic baffles at the soffit vents so the new depth wouldn’t block intake airflow. The homeowner’s summer cooling runtime dropped noticeably the first billing cycle after the top-off.
Attic Insulation Replacement
When existing insulation is contaminated, water-damaged, or distributed so unevenly that a top-off won’t achieve consistent coverage, we remove and replace. This is more common in Selma homes that have had roof leaks, rodent activity, or previous DIY attempts that compacted the existing material. Full removal, disposal, air-sealing, and re-insulation typically runs $3,200-$5,400 depending on attic square footage and accessibility.
Attic Baffles & Ventilation Prep
Selma’s vented soffit-and-ridge attic designs only work if intake airflow at the eaves stays clear. Without baffles, blown-in insulation drifts into the soffit vents and chokes the system. We install propper or equivalent baffles at every rafter bay before adding insulation, ensuring the attic can breathe. Baffle installation as a standalone prep service runs $400-$800; it’s included in our standard blown-in and top-up quotes.

Trusted Brands We Service in Selma
We don’t lock you into proprietary products. Our Selma jobs pull from Owens Corning, Johns Manville, GreenFiber, and Demilec materials - sourced through regional distributors with next-day availability for most items. That means no extended lead times because a specific SKU is back-ordered, and no pressure to accept a substitute you didn’t specify. If your home already has Owens Corning blown fiberglass and you want to match the existing product for a seamless top-off, we can do that. If you’re interested in the density and air-sealing performance of Demilec open-cell spray foam for a specific application - a bonus room over the garage, for instance - we’ll spec it and show you the blower-door difference.
Common Attic Insulation Problems We See in Selma Homes
- Settled original blown-in falling below effective R-value. That 1998 tract home near Retama Parkway probably left the builder with R-19 fiberglass labeled at full depth. After 25 years of 140°F attic cycling, it’s performing closer to R-8 or R-11. The ceiling plane is thermally thin exactly where San Antonio’s summer heat load hits hardest.
- Unsealed top plates and penetrations bypassing insulation entirely. Pre-IECC 2009 construction in Selma typically skipped air-sealing at the wall-to-attic junction. Heat and humidity migrate through can lights, wire penetrations, bath fan housings, and the attic hatch into your conditioned envelope - regardless of how many inches of insulation sit above them.
- Soffit vents choked by insulation drift, killing attic airflow. Vented soffit-and-ridge designs are standard in Selma’s tract homes, but without baffles, every blown-in top-off pushes material toward the eaves. Intake airflow dies. Attic temperatures climb higher. Sheathing cooks. We’ve seen this pattern repeat across neighborhoods from the original Evans Road builds to the later Forum-area phases.
- Post-Winter Storm Uri thermal envelope failures driving emergency calls. The February 2021 freeze exposed how thin many Selma tract-home envelopes really are. Pipe freezes in exterior walls, ice damming at the eaves, and extended furnace runtimes all traced back to insulation that had settled below code minimums decades earlier. We’re still doing assessment-driven replacement and upgrade work from that wake-up call.

What moves you within these ranges? Attic square footage is the big variable - a 1,400 square foot footprint with simple trusses sits at the low end, while a 2,800 square foot home with multiple HVAC platforms, vaulted sections, and limited access points pushes higher. Existing insulation condition matters too: removal and disposal adds labor and bag fees. Accessibility is the third factor - steep pitches, tight scuttle holes, or active storage in the attic space slow the crew and extend the day rate.

FAQs - Attic Insulation in Selma
Same-day or next-day scheduling is typical for Selma, with crews already routing through the Loop 1604/I-35 corridor. Call (830) 402-5240 - a live person answers 24/7, and we’ll give you a specific window, not a callback queue.
Yes. We work the original Evans Road tract homes, the Retama Parkway and Forum corridor builds, and the later phases near Cibolo Creek. The housing stock varies slightly by era - mid-1990s builds versus late-2000s construction - but the underlying pattern of settled pre-IECC 2009 insulation is consistent across Selma’s residential map.
We don’t treat insulation as an emergency trade - it’s not a burst pipe - but we do prioritize calls where thermal failure has created an immediate problem: post-storm water intrusion into attic insulation, rodent contamination requiring removal before occupancy, or extreme energy bills traced to identifiable envelope failure. In those cases, we can often assess within 24 hours and start work within 48. Call (830) 402-5240 to describe the situation.
Not meaningfully. Selma, Schertz, Cibolo, Universal City, and Converse all fall within the same regional pricing band. The bigger cost driver is housing era: a 1998 Selma tract home with settled original insulation and unsealed top plates needs more prep work than a 2018 Cibolo build that started with better code minimums. We price by what we find, not by ZIP code.
We most commonly use Owens Corning blown fiberglass for Selma attic top-offs - it matches the existing material in many local homes, maintains R-value stability across our extreme temperature range, and is readily available through regional distributors without extended lead times. For homeowners interested in cellulose, we also spec GreenFiber. We don’t push proprietary products or lock you into a single brand. The spec depends on your attic condition, your target R-value, and whether you’re matching existing material. Call (830) 402-5240 and we’ll walk through the options with a written price before any work starts.
All completed work is covered by our 365-Day Done Right Promise - if it’s not done right, we make it right. You also receive a written scope, written warranty, and Documented Photo Record before the crew leaves. On applicable jobs, before-and-after blower-door numbers are included so you can verify the air-sealing result in a single figure. Haven Standard: Have it in writing.
