Trusted Attic Insulation for Schertz Homeowners
Most attic insulation jobs in Schertz run between $1,800 and $4,500 depending on square footage, existing insulation condition, and whether air sealing is needed first. We’re typically on-site within 24 to 48 hours of your call, and same-day service is available for homes with no insulation or failed insulation creating immediate comfort or moisture issues. Call (830) 402-5240 to get a written price before any work starts.
We’ve sealed and insulated more than 9,000 homes since 2016, and we’ve learned that insulation without air sealing is just expensive padding. In Schertz, where summer attic temperatures regularly hit 140°F and winter cold fronts drop overnight lows into the 20s, your attic is the single largest thermal weak point in your building envelope. The homes we see in neighborhoods like The Crossvine, Copper Ridge, and Willow Grove often have original insulation that was adequate for 1990s building codes but falls short of what the 2021 IECC recommends for this climate zone. We don’t guess at the problem. Every attic job starts with a visual assessment and, when applicable, a blower-door test - a pressurization reading that shows, in one number, how much conditioned air your building envelope is losing. You get the number in writing before we propose anything.
What Our Attic Insulation Service Includes
Blown-In Attic Insulation
Blown-in insulation - loose-fill fiberglass or cellulose applied with a hose and blower - fills irregular joist cavities and covers existing insulation without the gaps that batt insulation leaves behind. In Schertz, we typically recommend blown-in for homes with standard truss attics, especially when the existing insulation has settled below the joist tops or has uneven coverage from prior DIY attempts. We use Owens Corning AttiCat and GreenFiber cellulose systems, and we never blow new material over an unsealed attic floor. Our crews seal top plates, electrical penetrations, and can-light housings first, then install to the R-value specified in your written scope.
Attic Batt Insulation
Batt insulation - pre-cut fiberglass or mineral wool panels - works best in attics with regular joist spacing, clear access, and minimal obstructions like ductwork or vaulted ceilings. We install Attic Batt Insulation in Schertz homes where the homeowner needs selective replacement, such as after rodent damage in a contained area, or where blown-in would interfere with future electrical or HVAC access. Our batts are cut to fit without compression, which is critical because compressed fiberglass loses up to 50% of its rated R-value. Every batt installation includes a photo record of the joist cavity before and after, so you can verify there are no gaps at the eaves or around penetrations.
Attic Insulation Top-Up
An Attic Insulation Top-Up adds loose-fill or batt insulation over existing material to reach current code levels without removing what’s already there. This is the most common attic service we perform in Schertz, particularly in homes built between 2000 and 2015 that started with R-30 or R-38 and now need R-49 or R-60 per current standards. We only recommend top-ups after verifying the existing insulation is dry, uncontaminated, and the attic floor is sealed. If your current insulation has been compressed by storage traffic, stained by roof leaks, or disturbed by rodents, we’ll document that and recommend removal and replacement instead. The written price you receive distinguishes between these scenarios so you know exactly what you’re paying for.
Attic Insulation Replacement
Attic Insulation Replacement means removing existing insulation, addressing any underlying air leaks or moisture damage, and installing new material to spec. We perform this service in Schertz homes with water-damaged insulation, heavy rodent contamination, or original material that has degraded past the point of effective performance. The removal process includes HEPA-filtered vacuum collection, disposal per local code, and a complete photo record of the bare deck before we seal and reinsulate. Replacement jobs always include our full air-sealing protocol - top plates, wire and pipe penetrations, recessed light housings, and chimney chases - because there’s no better opportunity to fix the envelope than when the attic floor is exposed.
Attic Baffles & Ventilation Prep
Baffles - also called vent chutes or rafter vents - are rigid channels that maintain airflow from soffit vents up through the attic space, preventing insulation from blocking intake vents and causing moisture buildup. In Schertz’s humid subtropical climate, blocked soffit ventilation is a leading cause of attic mold and premature shingle failure. We install baffles as part of our Attic Baffles & Ventilation Prep on any insulation job where soffit vents exist, and we assess whether your current intake and exhaust ventilation is balanced. A poorly ventilated attic in July here can reach 160°F, cooking your shingles from below and forcing your HVAC system to work against a radiant ceiling. Our written scope specifies baffle count and placement, and the photo record shows each one installed.

Brands We Service for Attic Insulation
We source and install materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in that limits your options or inflates your price. Our crews are trained on the specific handling requirements of each product. Owens Corning fiberglass systems, for instance, require particular attention to density and coverage uniformity to achieve labeled R-value, while Demilec open-cell spray foam demands precise substrate temperature and mixing ratios during application. We’ve installed Icynene spray foam in Schertz attics with complex geometries where loose-fill would be impractical, and we’ve used GreenFiber cellulose in homes where the homeowner prioritized recycled content and sound attenuation. Whether you have a preference for a specific brand or need guidance on what performs best for your attic’s condition and your budget, we can help.
We don’t claim exclusive or preferred status with any manufacturer. What we do guarantee is that the material specified in your written scope is the material installed, documented in the photo record, and covered by the manufacturer’s warranty plus our 365-Day Done Right Promise. If a product substitution is ever necessary due to supply constraints, you’ll approve it in writing before it reaches your attic.
Signs You Need Attic Insulation Right Now
- Your upstairs rooms are 8-15 degrees hotter than downstairs in summer. This is the most common complaint we hear from Schertz homeowners, especially in two-story homes with inadequate attic insulation or missing air sealing at the top plates. The temperature differential isn’t just uncomfortable - it’s a measurable sign that conditioned air is escaping into the attic faster than your HVAC can replace it.
- Your energy bills spike every July and August despite consistent thermostat settings. When attic insulation is thin, settled, or bypassed by air leaks, your air conditioner runs longer cycles to maintain setpoint. We regularly see Schertz homes where the attic accounts for 25-35% of total cooling load, and proper sealing and insulation cuts that by half.
- You can see the ceiling joists through your existing insulation. Fiberglass and cellulose settle over time, and if the insulation layer has compressed below the joist tops, you’ve lost effective R-value. In homes near the Guadalupe River floodplain with higher humidity, we’ve also seen insulation clump and settle unevenly due to moisture cycling.
- Ice dams formed on your roof during the February 2021 freeze or subsequent winter events. Ice dams occur when heat escapes through the attic, melts snow on the roof, and the water refreezes at the eaves. They’re rare in Central Texas but devastating when they happen, and they’re a definitive indicator of attic heat loss. Even one event means your envelope needs attention.
- You’ve had roof leaks, plumbing leaks, or rodent activity in the attic. Wet insulation doesn’t dry effectively in a ventilated attic - it compacts, grows mold, and loses thermal performance permanently. Rodents tunnel through fiberglass and contaminate it with waste. Both conditions require removal, deck sanitization, and replacement, not a top-up.
Our Attic Insulation Process - Step by Step
- 1
Schedule and arrival confirmation. When you call (830) 402-5240, a live person answers - no voicemail loops, no callback windows measured in business days. We schedule a specific arrival window, and you get a text when your technician is en route. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
- 2
Attic assessment and blower-door test. Your technician inspects the attic for existing insulation depth, condition, moisture damage, and ventilation status. On applicable jobs, we run a blower-door test to establish your home’s baseline air leakage rate in CFM50 - cubic feet per minute at 50 pascals of pressure. This number tells us whether air sealing should precede insulation, and it gives us a target for improvement.
- 3
Written scope and price. Before any work begins, you receive a written document specifying the insulation type, target R-value, air-sealing details, baffle count if needed, and total price. Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No surprises, no scope expansion after you approve.
- 4
Air sealing first, then insulation. Our crews seal all accessible leaks on the attic floor - top plates, electrical boxes, pipe and wire penetrations, recessed light housings, chimney chases, and duct boots. We verify the seal with a mid-process blower-door test on full replacement jobs. Only after the envelope is sealed do we install insulation to the specified depth and density.
- 5
Final test, documentation, and walkthrough. Where applicable, we run a final blower-door test and publish the before-and-after numbers so you can verify the air-sealing result. You receive a Documented Photo Record of the completed work, the written warranty, and a walkthrough of what was done and where. The 365-Day Done Right Promise applies from this moment - if it’s not done right, we make it right.
How Much Does Attic Insulation Cost in Schertz?
A typical attic insulation top-up in a 2,000-square-foot Schertz home runs $1,800-$2,800 depending on current insulation depth and the R-value needed to reach code. Full removal and replacement with air sealing typically ranges from $3,200-$4,500 for the same footprint, with larger homes in The Crossvine or Legacy of Schertz sometimes reaching $5,500-$6,800 if spray foam is specified for conditioned attic applications. Blown-in fiberglass generally costs 15-20% less than cellulose per square foot, while batt installation falls between the two but requires more labor for complex layouts.
Several factors move the price: attic accessibility (scuttle vs. pull-down stairs vs. walk-up), existing insulation condition, whether baffles and ventilation corrections are needed, and the presence of HVAC equipment or storage platforms that require detailed cutting and fitting. Homes in older Schertz neighborhoods like Old Town Schertz or Green Valley often need more extensive air sealing because construction practices in the 1970s and 1980s paid minimal attention to envelope tightness.
The most common way homeowners overpay is accepting a quote for insulation without air sealing, then discovering later that the new material isn’t performing because conditioned air is still escaping through the attic floor. We provide a Free Second Opinion on any written estimate - bring us a competing quote and we’ll read it with you, line by line, and explain where the scope differs from ours. Our written price includes all labor, materials, disposal, the photo record, and the blower-door testing. No line-item surprises.

Frequently Asked Questions - Attic Insulation in Schertz
Attic insulation is a thermal barrier installed between your conditioned living space and the unconditioned attic, reducing heat transfer that would otherwise force your HVAC system to work harder. In Schertz’s climate, proper attic insulation cuts cooling costs by 15-25% and eliminates the hot-second-floor problem that plagues homes with inadequate or degraded material. Without it, you’re paying to cool air that escapes into a 140°F attic in July.
Most attic top-ups and batt installations in Schertz are completed in a single day, typically 4-6 hours for a standard 2,000-square-foot home. Full removal, air sealing, and replacement takes 1-2 days depending on attic size, contamination level, and whether spray foam curing time is required. We specify the timeline in your written scope before work begins, and we don’t leave until the photo record and documentation are complete.
Attic insulation in Schertz typically costs $1,800-$4,500 for most homes, with top-ups at the lower end and full replacement with air sealing at the upper end. Spray foam applications or conditioned attic conversions can exceed this range. The exact price depends on your home’s square footage, attic accessibility, existing insulation condition, and whether ventilation corrections are needed. Call (830) 402-5240 for a written estimate - estimates are free, and you’ll have the price before any work starts.
