Blown-In Attic Insulation in Austin, TX
Blown-in attic insulation in Austin typically costs $1,200 to $3,800 for a full attic, depending on square footage, current insulation depth, and the R-value you’re targeting. Most homes in Austin need between R-38 and R-60, which translates to roughly 12 to 18 inches of blown-in fiberglass or cellulose. We complete most blown-in jobs in a single day, and every project starts with a written price before any work begins.

Blown-in insulation is loose-fill material (fiberglass or cellulose) that gets pneumatically blown into your attic floor cavities using a commercial blower machine. It’s the most common retrofit method for existing homes because it works around existing framing, electrical, and ductwork without tearing anything apart. As part of our larger Attic Insulation service area, blown-in is what we recommend for roughly 80% of Austin homes built before 2010 that still have their original insulation or only a thin layer of batting.
At Laurel Attic Insulation Austin, we run blown-in insulation differently than most crews in town. Every job includes the Relay Visibility Guarantee: a written price before work starts, live technician tracking so you know when we’ll arrive, and before-and-after photo proof of every square foot we cover. Our technicians are background-checked, uniformed, and they don’t do door-step surprises. The written price is the price. That’s how we’ve operated since 2003 as part of the Relay Home Co. family, and Chase Whitaker runs our Austin operation with one rule: if it’s not in writing, it didn’t happen.

When You Need Blown-In Attic Insulation
Most Austin homeowners don’t think about attic insulation until something forces them to. Here are the situations we see most often across neighborhoods like Allandale, Mueller, Circle C, and Hyde Park:
- Your upstairs rooms run 8 – 12 degrees hotter than downstairs. This is the number-one complaint in Austin’s older two-story homes, especially in neighborhoods like Brentwood or Crestview with 1960s – 1980s construction. The attic floor simply doesn’t have enough insulation to stop radiant heat from baking the ceiling below.
- Your energy bills spike every July and August. Austin’s summer heat is brutal, and if your attic insulation has settled to R-19 or less (common in homes built before 2000), your AC is working against a thermal hole above your head. Blown-in insulation added over existing batting is the fastest fix.
- You can see the tops of your ceiling joists. Walk up to your attic and look down at the floor. If the joists stick up above the insulation level, you don’t have enough. In Austin’s climate, we want insulation covering the joists completely and then some.
- Your existing insulation is compressed, water-stained, or has rodent damage. Blown-in fiberglass and cellulose lose R-value when they get compacted. If a roof leak or critter got in, that section needs to be removed and replaced. We handle insulation removal before blowing in fresh material.
- You’re buying an older home and want to negotiate a realistic repair credit. We provide attic inspections with square footage, current R-value, and a written quote you can use during your option period.
- You want to qualify for Austin Energy rebates. Austin Energy’s weatherization program has R-value requirements. We’ll tell you honestly if blown-in alone gets you there or if you need air sealing first.
The common thread: if your attic insulation is less than 10 inches deep, you’re paying more to cool your home than you need to, and Austin summers are only getting longer. Adding blown-in insulation is the single highest-ROI home improvement for comfort in this city.
Our Blown-In Attic Insulation Process
We run every blown-in attic insulation job in Austin the same way, and we put it in writing before we start. Here’s the exact process:
- Attic assessment and measurement. We inspect your current insulation depth, check for moisture, vents, wiring, and air leaks, and measure the actual square footage of your attic floor. We also look at your soffit ventilation to make sure adding more insulation won’t choke off airflow. This takes about 45 minutes.
- Written quote with R-value target. You get a line-item price before any work is approved. The quote states the material type (fiberglass or cellulose), the target R-value, the number of bags we’ll blow, and the final depth in inches. No verbal estimates that shift later. No “we’ll see how it goes.”
- Prep and air sealing. We seal penetrations around ceiling fans, recessed lights, and plumbing stacks where conditioned air escapes into the attic. We also install or repair baffles at the eaves so your soffit vents keep working. This step is often skipped by other crews, and it’s why their insulation underperforms.
- Blown-in installation. Our technician runs the blower hose into the attic and applies loose-fill insulation evenly to the specified depth. We use depth markers throughout the attic so you can see exactly how many inches went down. Materials come from brands we trust for performance in Austin’s heat, including Owens Corning fiberglass and GreenFiber cellulose.
- Photo documentation and final walkthrough. Before-and-after photos are sent to you through our Relay tracking link. You see the attic floor before, during, and after, along with the final depth measurements. Pay from the same link, and your written guarantee arrives with the digital invoice.
The whole process usually takes 3 to 6 hours depending on attic access and square footage. Attics in very old homes, say a 1920s bungalow in Travis Heights, take longer because the framing is tighter and we have to work more carefully around old knob-and-tube wiring situations. We’d rather go slow and do it right than damage something.
Materials We Use for Blown-In Insulation
We match material to the home, not to whatever is on the truck. For most Austin attics, we recommend Owens Corning AttiCat blown-in fiberglass because it resists moisture and doesn’t settle as much as older fiberglass products. For homes where attic baffles and ventilation prep are a priority or the homeowner wants better sound dampening, we recommend GreenFiber cellulose, which is made from recycled paper and packs more densely into wall cavities. In some high-humidity situations, we’ll use Johns Manville blown-in fiberglass with a slightly different binder that handles moisture better in older Austin homes with less-than-ideal ventilation.
You don’t need to know which material to choose. We’ll tell you what we’d put in our own home and why, and the written quote will show exactly what you’re getting.
Blown-In Attic Insulation Pricing in Austin
Here’s what attic insulation costs in Austin (2026 price guide), based on actual jobs we’ve done across the city. These are real numbers, not teaser rates:
| Attic Size | Target R-Value | Typical Cost |
|---|---|---|
| 800 – 1,200 sq ft attic | R-38 (14 – 16 in. fiberglass) | $1,200 – $1,900 |
| 1,200 – 1,800 sq ft attic | R-38 to R-49 | $1,800 – $2,700 |
| 1,800 – 2,500 sq ft attic | R-49 to R-60 | $2,600 – $3,800 |
| Small attic or room addition | R-38 | $700 – $1,200 |
What changes the price more than anything is the current state of your attic. If we need to remove old, water-damaged insulation first, that adds $1.50 to $2.50 per square foot for the removal. If your attic has no walkway or is hard to access, there may be an access fee. If you need air sealing, that’s usually $400 to $900 depending on how many penetrations we find. We’ll tell you all of this before you approve anything, and the quoted price is the price you pay.
We don’t do “free inspection, surprise invoice” games. The estimate is free, it’s in writing, and it’s yours to keep even if you decide to wait a year. Call (361) 321-0817 and we’ll schedule a time that works, not a four-hour window.
FAQs – Blown-In Attic Insulation
How much does blown-in attic insulation cost in Austin?
Blown-in attic insulation in Austin typically costs between $1,200 and $3,800 for a full attic, with most homes landing around $1,800 to $2,500 for R-38 coverage. The final price depends on attic square footage, current insulation depth, whether old insulation needs removal, and the target R-value. Our written quote before work starts means you’ll know your exact number before you decide anything. Call (361) 321-0817 for a free estimate.
Is blown-in insulation better than batting for an Austin attic?
For Austin retrofits, blown-in insulation is usually better than batting because it fills irregular spaces completely and doesn’t leave gaps around framing, ductwork, and wiring. Attic batt insulation works well in new construction when the attic is empty and accessible, but most existing Austin homes have obstacles in the attic that make blown-in faster, cleaner, and more effective at hitting the target R-value.
How long does blown-in attic insulation last?
Blown-in fiberglass and cellulose insulation in an Austin attic typically lasts 20 to 30 years before you need to add more, but that depends on roof leaks, pest activity, and how much the material originally settled. We see many 1990s-era Austin homes where the original blown-in fiberglass has settled from R-30 down to R-19 or less, and those attics are due for a top-up. Our 365-Day Done Right Promise covers the workmanship, and if anything is wrong with the install, we come back free.
Can you install blown-in insulation in one day?
Yes. Most blown-in attic insulation jobs in Austin are completed in a single day, usually 3 to 6 hours from setup to final photos. Larger attics or jobs that include insulation removal or extensive air sealing may take a second day, but we’ll tell you that upfront in the written quote. Call (361) 321-0817 and we’ll give you a straight answer on timing.
Do I need a permit for blown-in attic insulation in Austin?
In most cases, no. Adding blown-in insulation to an existing attic in Austin does not require a building permit, as long as no structural changes are made and the work stays within the attic envelope. If you’re also adding a new attic access or changing ventilation, that’s different, and we’ll flag it during the assessment. We handle every job to current Austin building code for attic ventilation and fire safety.
Why Choose Laurel Attic Insulation Austin for Blown-In Insulation
Laurel stays green all year, and so should your home’s comfort. That’s the idea behind the name, and it’s the practical benchmark we use on every job. We were founded in 2003 as part of the Relay Home Co. family, and we’ve built our reputation around one simple principle: make insulation transparent.
Few insulation contractors in Austin do that. Our customers are people who book everything on their phones, and they don’t have patience for a contractor who won’t pick up the phone or who hands them a different price at the door. That’s why calls to (361) 321-0817 are answered by a live person, 24/7. That’s why the Relay Standard exists: book in a tap, get a live arrival time, receive before-and-after photos, pay from the link. That’s why our 365-Day Done Right Promise is in writing on every job, not just mentioned in a sales pitch.
We’re also picky about materials. We work with eight leading insulation brands, and for blown-in attic jobs in Austin, we most often specify Owens Corning, GreenFiber, or Johns Manville. The brand gets matched to your attic’s specific needs, not to whatever is already loaded on the truck. That matters when you’re asking insulation to perform through 100-degree attic temperatures in July.
If you’re not sure where to start, we’ll help you figure it out during the free assessment. If you know what you need, even better. Either way, the next step is a call: (361) 321-0817.
