When You Need Blown-In Attic Insulation

Blown-in insulation uses loose fibers, either fiberglass or cellulose, that are blown into the attic cavity to fill every gap, corner, and irregular space. In Austin’s older housing stock, especially homes built before 1990 in neighborhoods like Hyde Park, Allandale, and Brentwood, original attic insulation is often thin, compacted, or missing entirely. Here’s what tips homeowners off that it’s time to add or replace blown-in insulation:

• Your upstairs rooms run 6 – 10°F warmer than downstairs in summer. That’s the classic sign of an under-insulated attic. Heat radiates through the ceiling all day, and your AC never catches up.
• Your electric bill spikes from June through September. Austin Energy customers with poor attic insulation can see cooling costs climb 30 – 40% above what a properly insulated home should cost. We hear this constantly from customers in Round Rock and Cedar Park too.
• You can see the tops of your ceiling joists. In many Austin attics, you’ll find 3 – 4 inches of old, flattened fiberglass batts. If you can see the joists, you’re dramatically under-insulated. Current Department of Energy guidance for Central Texas calls for R-38 to R-60, which translates to roughly 13 – 18 inches of blown-in material.
• Your attic has weird gaps, angles, or a tight pitch. Batts work fine in open rectangular attics, but they leave gaps around plumbing vents, recessed lights, chimneys, and knee walls. Blown-in insulation flows around obstructions and fills those gaps properly.
• You find rodent droppings or old pest damage in the attic. Rats and squirrels love nesting in fiberglass batts. Blown-in cellulose treated with borate is less inviting to pests and adds a measure of fire resistance.
• You’re prepping an older home for sale or a rental inspection. Buyers and inspectors in Austin now routinely check attic insulation levels. A home with R-13 in the attic is a negotiation problem waiting to happen.

Our Blown-In Attic Insulation Process

Garrett Sloane built Aspen Attic Insulation Austin around a simple idea: you should know exactly who’s coming to your home and exactly what you’ll pay before our Attic Insulation services start. That’s the Threshold Standard, and it applies to every blown-in insulation job we do.

1. You call and speak to a live person. Not a voicemail tree, not a call-back in 48 hours. Someone answers 24/7, takes your basic information, and schedules a free attic assessment at a time that works for you.
2. You receive your technician’s name and photo before the visit. We send it by text or email. When the doorbell rings, you know exactly who should be standing there. If anyone else arrives claiming to be from Aspen, the visit is free and we make it right. Every tech is background-checked, identity-verified, and arrives in a clean marked uniform with a photo ID badge.
3. We inspect the attic and measure. We check current insulation depth, look for air leaks around penetrations, assess ventilation, and identify any issues that need attention before insulation goes in, like recessed light clearances or bath fan venting.
4. You get a written price before any work starts. We hand you a line-item quote covering material, labor, and any prep work. That price does not change unless you change the scope. No surprise line items, no “we discovered something” phone calls mid-job.
5. We blow the insulation to the specified R-value. We use specialized equipment to install loose fibers evenly and to the depth we quoted. Material is matched to your attic: fiberglass from Owens Corning or Johns Manville for most homes, GreenFiber cellulose when you want the added fire and pest resistance. We never push one product because it’s what we have in the truck.
6. We walk you through the finished job. You see the depth, you see the even coverage, and we hand you a written copy of the 365-Day Done Right Promise. If anything fails within a year, the second visit is free.

Blown-In Attic Insulation Pricing in Austin

How Much Does Attic Insulation Cost? (2026 Price Guide) - Austin, TX: blown-in attic insulation typically runs $1.20 to $2.10 per square foot installed. For a 1,500-square-foot attic, that’s $1,800 to $3,150. Smaller attics in bungalows around Travis Heights or Rosedale often come in closer to $1,200 to $1,800 total, while large two-story homes in Avery Ranch or Steiner Ranch with 2,500-square-foot attics can run $3,500 to $5,000 depending on depth and prep work.

What moves the number:

• Target R-value. R-38 is the common baseline for Central Texas. Going to R-49 or R-60 means more material and more labor. The difference is usually 15 – 25% in total cost.
• Material choice. Cellulose runs slightly higher than fiberglass per square foot, but it settles into gaps more densely and offers better sound damping. We stock both and match the material to your attic, not our inventory.
• Old insulation removal. If your attic has pest-damaged, water-damaged, or moldy insulation, it has to come out first. That adds $1 – $2 per square foot for removal and disposal.
• Air sealing. Blowing insulation over unsealed penetrations loses real efficiency. We recommend air sealing can lights, top plates, and plumbing stacks in most older Austin homes. It typically adds $600 to $1,000 depending on the number of penetrations.
• Access and obstructions. Tight attics, low pitches, and half-story rooms in older Mueller or Crestview homes take longer. Labor is not a hidden fee; it shows up clearly on your written quote before we start.

Austin Energy runs a rebate program for attic insulation upgrades that can offset $400 to $1,200 of your project cost depending on the pre-existing R-value and total square footage insulated. Eligibility changes periodically, and we’ll tell you honestly whether your job qualifies. Call (325) 246-2929 and we’ll walk you through it. Estimates are free, and the written price you get is the price you pay.

FAQs – Blown-In Attic Insulation

These are the questions we answer most often from Austin homeowners considering blown-in attic insulation. Direct answers up front, then details.

Is blown-in insulation better than batts for an Austin attic?

Blown-in insulation is generally better than batts for most Austin attics because it fills irregular gaps, around pipes, wires, and framing, that batts leave open. In a city where attic temperatures reach 140°F in summer, those gaps matter. Batts work acceptably in a wide-open, rectangular attic with no obstructions, but real attics rarely look like that. Fiberglass batts also lose R-value when compressed or installed unevenly, which we see in almost every pre-2000 home we inspect across Central Austin. The trade-off is cost: batts are cheaper per square foot, but you’ll pay for the efficiency loss over time. Call (325) 246-2929 for a free attic inspection, and we’ll tell you honestly which approach makes sense for your roofline.

How long does blown-in attic insulation last?

Blown-in fiberglass insulation lasts 30 to 50 years in an Austin attic, while blown-in cellulose lasts 20 to 30 years before it settles enough to need a top-up. Settlement is the main issue. Cellulose settles about 10 – 15% over its first few years, which we account for by installing it slightly deeper than the target depth. Fiberglass settles less. Moisture is the real enemy. If your attic has a roof leak or poor ventilation, any insulation degrades faster. Our home page details how we handle attic ventilation during inspections. Every job we install carries a 365-Day Done Right Promise in writing, covering labor and materials.

Can I install blown-in attic insulation myself?

You can rent a blower machine from a home improvement store and blow fiberglass yourself, but doing it safely requires two people, proper protective gear, and careful attention around recessed lights and electrical junctions. We don’t recommend DIY for most Austin homeowners, not because it’s impossible, but because the cost difference is smaller than you’d think once you factor in rental, material overage, and the very real risk of stepping through a ceiling. More importantly, DIY work misses the Attic Baffles & Ventilation Prep and air sealing that makes blown-in insulation actually perform. A homeowner in Leander called us last year after a DIY job; the insulation was even, but the attic still leaked heat because nobody sealed the top plates. We fixed it in half a day. If you do attempt it, wear a proper respirator, use knee boards, and keep the blower hose away from any recessed can lights that aren’t rated for insulation contact.

How much does it cost to add blown-in insulation to an existing attic in Austin?

Adding blown-in insulation to an existing attic in Austin costs $1,500 to $3,200 for a standard 1,500-square-foot home, and the price depends on material type, target R-value, and whether air sealing is included. If your attic already has some insulation, topping up from R-19 to R-49 costs less than starting from bare joists. That’s because we’re adding material, not removing old batts. The ceiling of that range climbs when we’re working in tight attics with HVAC equipment and ductwork to work around. We give you a written price before any work starts, every time, no exceptions. If the number changes, it changes because you changed the scope, not because we found a surprise. Call (325) 246-2929 for a free quote and we’ll measure your attic at no charge.
