Blown-in insulation is exactly what it sounds like: loose material, usually fiberglass or cellulose, that gets blown through a hose into your attic floor cavities. It settles into a thick, even blanket that fills every gap, crack, and odd-shaped corner that batts and rolls leave behind. In Austin’s climate, where attic temperatures regularly climb past 140 degrees in August, that continuous coverage matters more than most homeowners realize. We’re part of the Attic Insulation in Austin team at Woolsey, and we’ve been insulating attics across Travis County since 2002, so we know exactly what this city’s heat does to a poorly insulated home.

When You Need Blown-In Attic Insulation

Most Austin homeowners don’t think about our Attic Insulation services until something forces them to. Here are the signs we see most often across neighborhoods like Allandale, Crestview, and Mueller:

• Your upstairs rooms are 8 to 12 degrees hotter than downstairs in summer. That’s the classic sign of thin attic insulation. Heat radiates down through the ceiling, and your AC runs constantly trying to fight it.
• Your energy bills spike every July and August. Austin Energy customers routinely report $300 to $500 summer bills when attic insulation sits at R-19 or lower. Upgrading to R-38 or R-49 typically cuts cooling costs by 15 to 20 percent.
• You can see the tops of your ceiling joists. If the existing insulation doesn’t cover the wood framing, you’re under-insulated. In Austin’s climate zone, the Department of Energy recommends R-38 to R-60 for attics.
• Your home was built before 1995. Most pre-1995 Austin homes were insulated to R-19 or R-30 at best. Many older homes in neighborhoods like Hyde Park and Bouldin Creek have settled insulation that’s performing far below its original rating.
• You feel drafts or notice uneven temperatures room to room. Gaps around recessed lights, plumbing penetrations, and bathroom fans let conditioned air escape. Blown-in insulation fills those gaps in a way batts simply can’t.
• You’ve had pest problems in the attic. Rats and squirrels love nesting in old fiberglass batts. Blown-in cellulose, treated with borates, resists pests and actually helps with fire resistance.

Our Blown-In Attic Insulation Process

We follow what we call The Kingswell Way on every single job: say the price, show up in the window, leave it cleaner than you found it, put the guarantee in writing, come back if it fails. Here’s how that plays out for blown-in insulation work in Austin:

1. Free inspection and measurement. We come out, measure your attic’s square footage, check the current insulation depth, and look for air leaks around ductwork, recessed lights, and the attic hatch. This takes about 45 minutes.
2. Written price, every time. Before we leave that first visit, you get a printed quote with the exact cost. No phone-call revisions, no door-step changes. That’s a Woolsey promise backed by the Kingswell Guarantee.
3. Prep work and air sealing. On install day, our background-checked, uniformed technicians seal the obvious air leaks first. We cover recessed lights with proper clearance barriers, dam up the attic hatch, and protect any areas that shouldn’t get insulation.
4. The blow-in, done right. We run the hose up through the attic access and blow the material to the depth we quoted. We install depth markers throughout the attic so you can see exactly what R-value you got, in every section, not just near the access point.
5. Cleanup and walkthrough. We vacuum up any stray material, sweep the area around the attic access, and walk you through what we did. You see the depth markers, you see the receipt, and you get the written guarantee in hand before we leave.

Blown-In Attic Insulation Pricing in Austin

Here’s what we’re seeing across Austin in 2026 for blown-in attic insulation work, based on a typical 1,500 to 2,000 square foot attic:

These ranges assume standard attic access and no major structural issues. Here’s what moves the number up or down:

• Existing insulation depth. The more you already have, the less material we need to add. The less you have, the more we blow in, and the higher the material cost.
• Material choice. Fiberglass loose-fill runs about $0.40 to $0.55 per square foot per R-10. Cellulose runs $0.45 to $0.65. Both are excellent options; we walk you through the tradeoffs honestly. We install GreenFiber cellulose and Owens Corning and Johns Manville fiberglass, so we can recommend what fits your house rather than what’s on the truck.
• Air sealing scope. If your attic has 20 recessed lights and a maze of ductwork, sealing gets more involved. We’ll show you exactly what we’re sealing and why.
• Attic accessibility. A pull-down ladder in a hallway is straightforward. A tiny access hatch in a 1940s Hyde Park bungalow takes more time and care.
• Old insulation removal. If you’ve had pests or water damage, the old material needs to come out first. Removal typically adds $1 to $2 per square foot.

Whatever your attic looks like, you’ll know the exact price before we schedule anything. Call (361) 418-9997 and we’ll come out, measure, and hand you a written quote on the spot. No obligation, no pressure, no surprises at the door.

Why Austin Homeowners Choose Woolsey for Blown-In Insulation

We didn’t start Woolsey to be the biggest insulation company in Texas. We started it to fix what was broken in the trade: contractors who quote one price and charge another, crews who don’t show up, jobs that fail and never get made right. The Kingswell Guarantee is our answer to all of it.

• Written price before any work begins. Every job, no exceptions. You see the number before we touch anything.
• 365-Day Done Right Promise. If your insulation isn’t performing within a year, we come back and fix it. Free. In writing. That’s not a sales line; it’s the guarantee we put on every single job.
• Background-checked, uniformed technicians. You know who’s walking into your home. Verified identity, professional appearance, and the training to do the job without cutting corners.
• A live person answers the phone, 24/7. No voicemail maze, no automated system, no call-back window. You call, we answer. It’s that simple, and it’s how we’ve operated since 2002.
• Material choice that fits your home. We install blown-in fiberglass and cellulose, and we’re not married to one brand. If your attic is better served by GreenFiber cellulose for pest resistance, that’s what we’ll recommend. If Owens Corning fiberglass makes more sense for your budget, we’ll tell you that too.

The Kingswell Guarantee and What It Covers

Wool was the first insulation. Woolsey keeps the idea in the name. We started as part of the Kingswell family of independently owned and operated insulation companies in 2002, and we’ve held ourselves to one standard since day one: do the job right, put every promise in writing, and stand behind it for a full year.

The Kingswell Guarantee covers four things on every blown-in insulation job:

• A written price before work starts. Not an estimate that might change. The price.
• A committed arrival window. We show up when we say we’ll show up. If we’re running late, you’ll know before we’re late.
• A clean job site. We treat your home like we’d want someone to treat ours. No stray insulation in the hallway, no boot prints on the carpet, no mystery debris in the driveway.
• A written guarantee on the work. If your insulation fails within 365 days, we come back and fix it at no charge. A free second visit if anything isn’t right.

That’s the whole thing, in writing, every time. It’s why homeowners in Austin neighborhoods like Circle C, Tarrytown, and Brentwood call us when their attic insulation needs a real fix.

FAQs – Blown-In Attic Insulation

How much does blown-in attic insulation cost in Austin?

Blown-in attic insulation in Austin typically costs between $1,800 and $4,600 depending on attic size, existing insulation depth, and whether air sealing is included. A top-off on a 1,500-square-foot attic usually runs $1,800 to $2,600, while a full removal and re-insulate to R-49 can reach $4,600. We give you the exact written number before any work starts. Call (361) 418-9997 for a free estimate.

Is blown-in insulation better than batts for Austin attics?

For most Austin attics, yes, because blown-in insulation forms a continuous thermal blanket with no gaps at joists, plumbing vents, or odd angles where heat leaks through. Attic Batt Insulation leaves seams and gaps that add up to real heat gain in a Texas summer. Blown-in also makes it far easier to reach the exact R-value depth you need, and it’s faster to install.

How long does blown-in attic insulation last?

Properly installed blown-in insulation lasts 20 to 30 years in Austin, though it can settle slightly over time and lose performance. Fiberglass loose-fill settles more than cellulose in most cases, which is why we install depth markers and account for settling when we quote your target R-value. If your insulation is more than 15 years old, it’s probably worth a free inspection to see how much R-value you’ve actually lost.

Can you blow insulation over existing insulation?

Yes, in most Austin homes we can blow new material directly over existing insulation, as long as the old material isn’t wet, pest-infested, or full of debris. This top-off approach is the most cost-effective way to upgrade from R-19 to R-38 or higher. If there’s old water damage or rodent activity, we’ll recommend removal first and explain exactly why it matters for your home’s health and energy performance. We also handle Attic Baffles & Ventilation Prep to ensure proper airflow before installing new material.

Does blown-in insulation help with Austin’s summer heat?

Yes, it’s the single most effective upgrade for reducing heat gain through your ceiling in Austin’s climate. Attic temperatures here regularly exceed 140 degrees in summer, and without proper insulation depth that heat pushes straight down into your living space. Upgrading from R-19 to R-38 typically cuts upstairs temperatures by 5 to 8 degrees and reduces cooling costs by 15 to 20 percent. We see it every single week in July and August.

Can you come out today for an estimate?

In most cases, yes. Our phones are answered by a live person 24 hours a day, 7 days a week, so you can call (361) 418-9997 right now and we’ll schedule a free inspection at a time that works for you.
