Attic Batt Insulation in Schertz, TX

Attic Batt Insulation in Schertz, TX

Attic Insulation services in Schertz typically run between $1.50 and $3.20 per square foot installed, depending on the R-value specified and whether air sealing is completed first. Most single-story homes in the Schertz area fall in the $900 to $2,800 range for a full attic batt job. Work is scheduled within the week and completed in a single visit on most projects.

Batt insulation – pre-cut fiberglass or mineral wool panels fitted between joists and rafters – is one of the cleaner installation methods available for attics with standard framing. When the bays are laid out evenly and the batt thickness matches the R-value the home actually needs, it performs well for decades. The problem we see most often in Schertz is not the batts themselves. It’s that they were laid over an attic floor that was never properly air sealed, which means conditioned air is still flowing freely into the attic through gaps around top plates, can lights, and plumbing penetrations before it ever hits the insulation.

At Topside Attic Insulation Schertz, we don’t start installing batts until the attic floor is sealed. That’s the order of operations, and it doesn’t change. Air sealing is completed first – every top plate gap, every recessed light boot, every wire and pipe penetration – and then we install the insulation on top of a sealed envelope. If you’d like to understand what that process looks like across all attic insulation methods, our Attic Insulation in Schertz page covers the full picture. And if you have a competing estimate already in hand, call us at (830) 402-5240 – we’ll read it with you and give you a written price of our own before anyone touches your attic.

We’ve been operating under The Haven Standard since 2016, which means every job begins with a written scope and a flat price, and closes with a documented photo record. No work starts without both. That’s Haven Standard Clause 1, and it’s not optional.

When You Need Attic Batt Insulation

• Your second floor stays 5 to 8 degrees warmer than the first, even with the AC running. This is one of the most common complaints we hear from homeowners in Schertz subdivisions like Greenshire Estates and Crossvine. In a Central Texas summer, an attic sitting at 140°F with inadequate batt coverage underneath radiates heat directly into the living space above.
• Your attic has old, compressed, or missing batts. Fiberglass batts lose effective R-value when they’re compressed, wet, or have shifted away from the framing bays. If you can see exposed joists or daylight between sections, the insulation is no longer performing as rated.
• Your energy bills have climbed year-over-year without a change in usage habits. A blower-door test – a pressurization reading that shows, in one number, how much air your building envelope is losing – often reveals that the attic is the primary source. Batts alone don’t fix this, but properly installed batts over a sealed floor will.
• You’re finishing a room addition or converting a bonus room. New framing in Schertz homes often sits above unconditioned attic space. Getting the correct batt R-value specified before drywall goes up is much easier than correcting it afterward.
• You had spray foam quoted but the space doesn’t require it. Open-cell spray foam like Icynene is excellent for cathedral ceilings and irregular framing, but for a standard vented attic floor with consistent joist spacing, batts deliver comparable thermal performance at a lower installed cost. Not every attic needs the most expensive product, and we’ll tell you which one fits.
• Your home was built between 1985 and 2005 and has never had an insulation update. A large share of the older housing stock in Schertz was built to code minimums that are now well below current energy standards. The IRC currently calls for R-38 to R-60 in Climate Zone 2, which covers Guadalupe County – many of these homes were finished with R-19 or less.

Our Attic Batt Insulation Process

1. Written scope and price before any work starts. We measure the attic – square footage, joist spacing, existing insulation depth and condition – and give you a flat written price the same day. Haven Standard Clause 1 is non-negotiable: you have the price, scope, and warranty in writing before we schedule the install. No surprises when the crew arrives.
2. Blower-door baseline reading. Before we touch anything, we run a blower-door test to establish how much air the home is losing through the envelope. This number – measured in CFM50, cubic feet per minute at 50 pascals of pressure – becomes the “before” figure in your documented record. On attics we’ve tested in Schertz, we regularly see readings between 3,500 and 5,800 CFM50 in homes that haven’t been air sealed. You get this number in writing.
3. Attic floor air sealing – sealed first, before any insulation goes in. Every top plate gap is sealed with two-part foam. Every recessed light boot, every plumbing stack, every wire penetration gets sealed and documented with photos. This step is not optional and it’s not an upsell. Laying batts over an unsealed floor is, in our view, an incomplete job, and we won’t do it that way.
4. Post-sealing blower-door reading. After air sealing is complete, we run the test again. The “after” number goes into your documented record alongside the “before” reading. We’ve seen properly sealed attic floors drop whole-home air leakage by 30 to 50 percent on their own, before a single batt is installed. You see that number. We publish it.
5. Batt installation to specified R-value. We cut and fit Owens Corning batts – or another product from our supply line, depending on availability and project spec – to fill each joist bay flush and continuous. No gaps at the edges, no compression at obstructions, no voids around cross-bracing. If the spec calls for a double layer to reach R-38 or R-49, the layers run perpendicular to each other so the seams don’t align. Every section is photographed.
6. Documented photo record delivered at close-out. Before we leave your property, you receive a photo record of the completed attic floor – including the sealed penetrations, the installed batt coverage, and the blower-door readings. This is included on every job. You’re not requesting it; we’re providing it because that’s what leaving looks like under the Haven Standard.

Attic Batt Insulation Pricing in Schertz

Attic batt insulation in Schertz runs between $1.50 and $3.20 per square foot installed for the insulation itself. Air sealing – which we complete as a hard prerequisite on every job – is priced separately and typically adds $350 to $850 depending on attic complexity and the number of penetrations. Here’s how most projects break out:

Several factors shift the final number up or down. Attics with many recessed lights – common in Schertz homes built in the early 2000s – take longer to seal properly and that’s reflected in the price. Homes requiring removal of old, damaged batts before new installation add a disposal cost, typically $0.30 to $0.60 per square foot for removal. Reaching R-49 or R-60 (the upper end of what Climate Zone 2 code supports) requires a double layer, which adds material and labor.

We don’t quote over the phone because a number given without a measurement isn’t a price – it’s a guess that sets you up for a change order conversation later. Under Haven Standard Clause 1, you get a flat written price after we’ve seen the attic. Call (830) 402-5240 to schedule a free estimate – we measure, we price it in writing, and you decide.

FAQs – Attic Batt Insulation in Schertz

What R-value do I need for attic batt insulation in Schertz, TX?

Schertz sits in IECC Climate Zone 2, and the current energy code for that zone calls for R-38 minimum in attic floors, with R-49 to R-60 recommended for new construction and upgrades. Most older homes in Schertz were built to R-19 or R-25 – well below current minimums. When we inspect an attic, we measure the existing depth, calculate the actual R-value in place, and specify exactly what’s needed to reach the target. You’ll see those numbers in your written scope before we install anything. Call (830) 402-5240 to schedule a free measurement.

How long does attic batt insulation installation take?

Most attic batt installations in Schertz are completed in a single day. A standard single-story home with 1,000 to 1,400 square feet of attic space – including the air sealing phase and both blower-door readings – typically runs 4 to 7 hours for a two-person crew. Larger two-story homes, or attics with significant existing material to work around, can extend into a second day. We’ll tell you the expected timeline in the written scope before we schedule.

Is it cheaper to repair or replace damaged attic batts?

Attic Insulation Replacement is cheaper when only partial and the damage is isolated – a section that got wet from a roof leak, for example, or a few bays where batts were disturbed during HVAC work. Full replacement makes more sense when the existing material is widespread, compressed below useful R-value, or contaminated (rodent activity, mold). We’ll photograph the existing condition during the estimate visit and show you exactly what we found. In Schertz attics we inspect regularly, partial repairs in homes from the 1990s often reveal that the surrounding batts are also degraded once we start pulling sections, so we document everything before the job so there’s no ambiguity about what was pre-existing. Call (830) 402-5240 and we’ll give you an honest written assessment.

Can you install batt insulation without air sealing the attic first?

We won’t. Air sealing and batt installation are not interchangeable – they do different things. Batts slow heat transfer through conduction. Air sealing stops conditioned air from escaping through gaps in the building envelope. Without sealing first, every gap around a top plate or recessed light becomes a bypass that defeats the insulation above it. Our blower-door readings from Schertz attics show consistently that air sealing alone can cut whole-home air leakage by 30 to 50 percent before a single batt goes in. Skipping that step and installing batts over unsealed gaps is an incomplete job. We’ve been doing it in the correct order since 2016, and that’s not going to change.
