Cellulose Insulation

Cellulose insulation is loose-fill material made primarily from recycled paper treated with fire retardants, and it’s one of the most effective options for Austin’s hot, humid climate. We recommend it for attics with irregular joist spacing, old rock wool that’s settled, or homeowners who want maximum coverage per dollar. Aspen Attic Insulation Austin installs GreenFiber cellulose, blown to the R-value your attic actually needs, not just the minimum code says. In Austin, cellulose for a 1,500-square-foot attic runs $1,200 to $2,600 installed, depending on depth and existing material. You get the written price before we start, and every job carries the 365-Day Done Right Promise.

Dense coverage for odd-shaped attics

Cellulose settles into corners, around can lights, and over cross-bracing in ways batts never will. That matters in Austin’s older neighborhoods like Hyde Park and Bouldin Creek, where attic framing often follows no standard spacing. We blow it to consistent depth, then back it with a written R-value confirmation.

Why GreenFiber over generic cellulose

GreenFiber gives us consistent density and a fire-retardant treatment that’s independently tested. We don’t mix unknown reclaimed material into your attic. You know exactly what product goes in, and that product name is on your written invoice.

Blown In Attic Insulation

Blown in attic insulation is the loose-fiber method used to cover an attic floor evenly, filling gaps that leave rooms hot in summer and cold during Austin’s January freezes. You need it when your current insulation is below R-30, has settled below the joists, or shows signs of rodent damage. Aspen Attic Insulation Austin starts every attic job with a free inspection and a thermal assessment, so we’re not guessing where your house loses energy. Typical Blown In Insulation pricing in Austin runs $1,500 to $3,500 for a standard single-story home, fiberglass or cellulose included. Your price is written before work begins, and it does not change after.

Attic prep that other crews skip

We check soffit ventilation, bathroom fan terminations, and can light clearances before blowing anything in. Those details stop moisture problems before they start. If a vent needs relocating or a light needs a protective dam, we tell you and price it up front.

What you see after we leave

You should see a uniform blanket of insulation at the depth we agreed on, with marker flags showing the R-value in each attic zone. No bare patches, no insulation dumped over the hatch. Garrett holds every crew to that standard, and he checks the photos from every job.

Blown In Cellulose Insulation

Blown in cellulose insulation is the application of treated recycled paper fibers across an attic floor, and it’s the best choice for homeowners who want a dense thermal barrier at a mid-range price. Austin homes built before 1990 often have thin fiberglass batts that leave R-values in the low teens. We blow cellulose over or in place of those batts to bring your attic to R-38 or R-49, depending on your home’s construction. Blown in cellulose insulation in Austin typically costs $1,300 to $2,900 for an average attic, including removal of surface debris and marking the final depth. And because your price is in writing first, you never get a surprise at the end.

Fire retardant and pest resistant by design

Cellulose treated with borate has two advantages Austin homeowners care about: it resists ignition and discourages roaches and silverfish. The treatment lasts the life of the material, not just the first year. That’s real protection for older pier-and-beam homes where pests are already a challenge.

When to choose cellulose over fiberglass

Choose cellulose when your attic has tricky geometry, when you want the best air-sealing performance per inch, or when you’re replacing old material and want something with higher recycled content. We’ll show you both options and the installed cost for each. Then you decide, not us.

Blown In Fiberglass Insulation

Blown in fiberglass insulation is loose fiberglass blown to a specified depth and density, and it’s a strong option for Austin attics that need a lightweight, moisture-resistant material. We install Owens Corning and Johns Manville blown fiberglass, both of which hold their R-value for decades when kept dry. You’d choose fiberglass when your attic has good air sealing already or when you want the lightest material available over older ceiling drywall. Blown in fiberglass insulation in Austin runs $1,400 to $3,200 for the average attic, with the final depth confirmed by ruler and photo. The price you’re quoted is the price you pay, written down before we open the machine.

Lighter weight for older ceilings

Fiberglass weighs less per installed R-value than cellulose, which makes it a smart pick for 1950s and 1960s Austin homes with older ceiling framing. We check joist spacing and drywall thickness before recommending it. On most homes both materials are safe; on some older builds, fiberglass is the better call.

Knauf and Owens Corning, not mystery fiber

We buy from name-brand manufacturers with published performance data. You get the product datasheet with your invoice. If you want to verify the R-value claim later, the numbers are right there, tied to your attic’s installed depth.

Loose Fill Insulation

Loose fill insulation is the category name for any blown-in fiber product, cellulose or fiberglass, installed as a loose blanket rather than batts or boards. In Austin, it’s the most common retrofit for existing attics because it conforms to every framing irregularity without leaving seams. You need it when rooms over the garage stay hot, when your upstairs AC runs constantly in August, or when you can see the tops of your ceiling joists through the existing insulation. Aspen Attic Insulation Austin installs our Blown In Insulation in Cedar Park and across Austin for $1,200 to $3,300, depending on square footage, target R-value, and how much old material needs removing. Your written quote covers everything: material, labor, disposal, and the final R-value verification.

R-value you can verify before paying

We don’t leave until we’ve measured depth in multiple spots and shown you the coverage map. If the depth doesn’t match the plan, we fix it before you sign off. That’s the Threshold Standard, and it applies on every job, no exceptions.

Air sealing comes first, always

Blowing insulation over unsealed penetrations wastes a third of the benefit. We seal top plates, can light gaps, and plumbing penetrations before the blower starts. The sealing work is bundled into your written price.

Blown In Insulation Contractors

Blown in insulation contractors in Austin range from one-man operations with a rented blower to established companies with trained crews and real guarantees. The difference shows up in coverage consistency, attic damage, and whether anyone tests the final R-value. Aspen Attic Insulation Austin sends background-checked, uniformed technicians whose name and photo you receive before they arrive. Every tech is identity-verified under the Threshold Standard, and they show a photo ID badge at the door. A full attic job typically runs $1,500 to $3,800 with our team, and the 365-Day Done Right Promise means a free second visit if anything isn’t right. Call (325) 246-2929 for an estimate. A live person answers, even at midnight on a Sunday.

Who actually shows up at your door

We tell you before the appointment. Name, photo, badge number, and what the truck looks like. If anyone else arrives at your door claiming to be from Aspen, the visit is free and we make it right. That’s not a marketing line; it’s our written policy.

Why the Threshold Standard matters

The Threshold Standard is our internal verification system: every hire is background-checked, every tech is identity-verified, and every job gets a photo audit before we close it out. We built it for homeowners who don’t want to wonder who’s in their attic. You shouldn’t have to ask if the person was vetted; it should already be true.

Brands We Service

We install GreenFiber cellulose on most Austin retrofit jobs because it delivers consistent density and has the borate treatment we believe in. Our crews are trained on GreenFiber’s application specs, from target density per square foot to the exact blower settings that produce even coverage without overpacking.

We also install Owens Corning and Johns Manville blown fiberglass for homeowners who prefer that material. Both brands publish verified performance data, and we match their specs exactly so the installed R-value is real, not theoretical. Whether you end up with GreenFiber, Owens Corning, Johns Manville, or any other material we stock, the written price and the 365-day guarantee stay the same.

Signs You Need a Pro Right Now

• Upstairs rooms run 10 degrees hotter than downstairs. That’s rarely an AC problem. It’s usually a thermal break in the attic, and the longer you wait, the harder your compressor works and the sooner it fails.
• Your energy bills spiked compared to last year. Austin summers are hot, but a year-over-year jump with no change in usage usually means your insulation has settled or gotten damp. A quick attic check tells us which one.
• You can see the ceiling joists through the insulation. Exposed joists mean your attic insulation is below R-19 in most Austin homes. That’s the point where the attic is actively costing you money every single day.
• There’s a musty smell upstairs after rain. Wet insulation loses its R-value and grows mold. That’s not a wait-and-see situation. We find the leak, remove the damaged material, and replace it. Written price first.
• Rodents or pests have been in the attic. They nest in insulation and leave droppings that affect indoor air quality. We remove contaminated material, sanitize where needed, and blow in fresh insulation at the correct depth.

Our Process, Step by Step

1. 1
   Call and get a real person. Austin homeowners reach us 24/7 at (325) 246-2929. We ask a few questions, schedule a time that works, and confirm who’s coming before we hang up. You don’t leave a message and wait.
2. 2
   Free attic inspection and measurement. Our technician walks the attic with a moisture meter, checks existing depth, and photographs the problem areas. You see what they see. No open-ended “it might cost more” language.
3. 3
   Written price before any work begins. We put the scope, materials, depth targets, and total price on paper. The number doesn’t change. If we find something unexpected mid-job, we stop, tell you, and get your approval before proceeding.
4. 4
   Prep, air seal, and blow. We seal top plates, plumbing penetrations, and can light gaps, then blow the material to consistent depth. The tech checks density as the machine runs and adjusts on the fly. Most Austin attics finish in four to six hours.
5. 5
   Verification and photo audit. Before we leave, we measure final R-value at multiple points and photograph the finished attic. You get the photos and the written R-value confirmation. If anything falls short, we fix it under the 365-Day Done Right Promise at no charge.
