Fast, Reliable Attic Insulation Across Schertz
Most attic insulation jobs in Schertz run $1,800-$4,200 depending on whether we’re topping off settled fiberglass or pulling degraded material and starting fresh. Our crews are typically on-site in Schertz within 24-48 hours of your call, and we bring a written price before anyone sets foot in your attic. Dispatch and scheduling run through our San Antonio office, but the crew that arrives at your door knows Schertz’s subdivisions, its builder-era housing stock, and the specific failure patterns that drive summer electric bills past $350 in this market.

Why Topside Attic Insulation Schertz Is Schertz’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a significant share of those have been in Schertz’s production-builder subdivisions where the original insulation was never adequate for South Central Texas heat. Our Schertz customers leave reviews that specifically mention the blower-door numbers we publish, the photo documentation they received, and the fact that we started with a written price - not a ballpark that changed once the crew arrived.
Response time to Schertz is same-day or next-day for most calls, because our crews work this corridor regularly. We know which Fairhaven streets have the 2006-era DR Horton homes with the thin blown fiberglass, where Belmont Park’s slab-on-grade layouts create tricky attic access, and why Ashley Place homes built during the 2009-2012 rush often need baffles installed before any new insulation goes in. That local knowledge means we don’t waste your time with a generic scope that misses the actual problem in your attic.
Every job is backed by our 365-Day Done Right Promise, and every homeowner gets a written warranty before work starts - Haven Standard Clause 1, no exceptions.
Our Attic Insulation Services in Schertz
Blown-In Attic Insulation
We install blown fiberglass and cellulose to densities that hold their R-value in Schertz’s 140-155°F attics. Our crews use Owens Corning and GreenFiber products, selected for thermal stability in extreme heat rather than just nominal bag coverage. In Schertz, we typically see builder-grade blown fiberglass that was installed to a fluffy, uncompressed R-30 but has since settled to an effective R-18 to R-22. We measure what’s there, air-seal the attic floor first, then blow to a settled R-38 or R-49 depending on your ceiling assembly and energy goals.
Attic Batt Insulation
Batt insulation has a place in Schertz, mostly in new additions or finished attic spaces where blown material won’t perform well. We source Knauf and Johns Manville batts for local jobs, and we install them with proper cavity fill - no compression at electrical boxes, no gaps around framing. In Schertz’s tract homes, batt retrofits are less common than blown top-ups, but when we do use batts, it’s because the application demands it, not because it’s easier to stock.
Attic Insulation Top-Up
This is our most frequent call in Schertz. Homes in Fairhaven, Belmont Park, and Ashley Place were built with minimum-code R-30 blown fiberglass that has degraded over 10-20 years of attic heat cycling. Our crew pulls hatch measurements, photographs the existing depth, and calculates the gap between what’s there and what should be. A typical Schertz top-up runs $1,800-$2,800 for a 1,800-2,400 square foot home, including air sealing of top plates and can lights before the new material goes in. The result is documented with before-and-after photos and, on request, blower-door numbers that show the actual air-leakage reduction.
Attic Insulation Replacement
When existing insulation is contaminated, water-damaged, or degraded beyond recovery, we remove it and start fresh. In Schertz, this is most common after rodent activity in the attic or following roof leaks that saturated the fiberglass. Replacement jobs run $3,200-$4,800 for typical tract-home footprints, including full removal, attic floor air sealing, and new blown fiberglass to R-38 or R-49. We handle the disposal; you get photos of the empty cavity and the finished job.
Attic Baffles & Ventilation Prep
Mid-2000s homes along FM 1518 and FM 3009 were frequently built without soffit baffles, the channels that keep insulation from blocking intake vents at the eaves. Without them, wind washing pulls loose fiberglass away from the edges and chokes the ventilation path. We install proper baffles before any top-up, ensuring your attic can breathe. In Schertz’s climate, a well-ventilated attic with sealed air barriers performs dramatically better than a stuffed, choked cavity - and we document the baffle installation in your photo record.

Trusted Brands We Service in Schertz
We stock Owens Corning, GreenFiber, and Knauf insulation products for Schertz jobs, with no proprietary lock-in that limits your options. Owens Corning blown fiberglass is our standard for attic top-ups in this market because it holds density well in high-heat cavities. GreenFiber cellulose performs well for homeowners prioritizing recycled content and sound dampening. Knauf supplies our batt and dense-pack applications. We source locally through San Antonio distributors, so material lead times don’t delay your job. Every bag is documented in your written scope, and we don’t substitute brands mid-project without your approval in writing.
Common Attic Insulation Problems We See in Schertz Homes
- Settled builder-grade fiberglass below effective R-20. The blown fiberglass installed in Fairhaven, Belmont Park, and Ashley Place during the 2000s-2015 boom was measured loose and fluffy, not settled and compressed. After a decade of attic heat cycling, most of it sits at 6-8 inches - an effective R-18 to R-22, not the R-30 on the builder’s documentation.
- Missing soffit baffles causing wind washing at eaves. Homes along FM 1518 and FM 3009 frequently lack baffles, so intake ventilation is blocked and loose insulation migrates away from the edges. The ceiling gets cold spots, the attic overheats, and the HVAC runs longer.
- Unsealed top plates and can-light penetrations. Even homes with adequate R-value leak conditioned air through gaps at wall top plates, recessed can lights, and plumbing chases. In Schertz’s 100°F summers, that’s direct heat gain and direct energy loss.
- Undetected degradation in short-tenure military rentals. JBSA-Randolph families turn over every 2-4 years, so attics rarely get inspected. The insulation keeps settling, the bills keep climbing, and no one connects the two until a permanent resident finally calls us.

FAQs - Attic Insulation in Schertz
You almost certainly don’t have R-30 anymore, even if the builder’s sticker says so. In Fairhaven, our crew pulled hatch measurements on a 2006 DR Horton single-story and found the original blown fiberglass sitting at about 6 inches - an effective R-18, not the R-30 on the builder’s sticker. We air-sealed the top plates and can lights, dropped in Owens Corning blown fiberglass to R-49, and the homeowner’s July attic probe dropped from 152°F to 128°F. Same story two streets over in Belmont Park, except that one also needed baffles at the soffit vents before we could top off. Call (830) 402-5240 for a free assessment of what’s actually in your attic.
We measure it. Our crew pulls hatch measurements at multiple points, photographs the depth, and calculates effective R-value based on the material type and compression. For Schertz’s 2000s-era blown fiberglass, anything under 10-12 inches settled depth is below current code and well below what South Central Texas heat demands. You’ll also see the symptoms: $350+ summer electric bills, rooms that won’t cool evenly, and ceiling registers blowing warm air in July. We’ll show you exactly what we found and what it means in dollars. Call for a free estimate with written findings.
Yes, because the payback is faster than most homeowners expect. A typical Schertz top-up at $2,200 saves $60-$100 monthly on summer electric bills in this market, meaning full payback in 2-3 cooling seasons. When you sell, documented energy improvements also differentiate your listing in a military-heavy market where buyers compare utility costs carefully. We provide the written scope, photo documentation, and blower-door numbers that transfer cleanly to your buyer’s due diligence. Call (830) 402-5240 to run the numbers for your specific home and timeline.
Attic insulation in Schertz should be evaluated for both extremes, not just summer heat. Uri exposed what South Texas builders had long ignored: R-30 fiberglass in a vented attic doesn’t protect ceiling-mounted ducts or plumbing chases when temperatures drop to 4°F for 72 hours. We address this by air-sealing the attic floor first - stopping the stack effect that pulls warm, moist air into the cavity where it can condense and freeze - then insulating to R-38 or R-49 with material that performs at temperature extremes. The same assembly that keeps 155°F attic heat out in August keeps your conditioned air in during a hard freeze. Call for a scope that addresses both seasons.
Our crew arrives at the scheduled window, confirms the written scope with you, and accesses the attic through the existing hatch. We photograph the existing insulation depth, remove any debris or contamination, air-seal top plates and penetrations with foam and caulk, install baffles at soffit vents if they’re missing, then blow new fiberglass to the specified R-value. For a typical 2,000 square foot Schertz home, the work takes 4-6 hours. You receive a Documented Photo Record, the written warranty, and on request, before-and-after blower-door numbers. No work starts without your approved written price. Call (830) 402-5240 to schedule.
