Trusted Attic Insulation for Austin Homeowners
Attic insulation in Austin isn’t a luxury, it’s the difference between a July electric bill that stings and one that knocks you sideways. We’re Woolsey Insulation Austin, and we’ve been insulating attics across this city since 2002, led by Glenn Hartley as part of the Kingswell family of independently owned and operated insulation companies. Most Austin attics we inspect are under-insulated, often by half the R-value the Texas climate demands. That means your AC runs longer, your upstairs rooms never quite cool down, and your money leaks through the ceiling every single month. We fix that with honest, written pricing before any work starts, and a 365-day guarantee in writing on every job. Same-day and next-day appointments are available across Austin. Call (361) 418-9997 and a real person answers, 24/7.
Key Takeaways
- Most Austin attics are under-insulated. The Department of Energy recommends R-38 to R-60 for our climate zone, and most homes we inspect sit well below that.
- Written pricing before we touch anything. No door-knock renegotiations, no surprises. The Kingswell Guarantee puts the number on paper first.
- We only do insulation. Attic insulation and spray foam, nothing else. That focus means we’ve seen every attic condition Austin can throw at us.
- 365 days of accountability. If it isn’t done right, we come back at no charge. In writing, on every job.
From home inspections to full attic retrofits, Woolsey covers the entire Austin metro with a simple promise: say the price, show up when we say, leave it cleaner than we found it, and stand behind the work for a full year.
Blown In Insulation
Blown in insulation is exactly what it sounds like: loose insulation material, usually fiberglass or cellulose, blown into attic spaces through a hose at high volume. It fills irregular spaces, gaps around framing, and hard-to-reach corners far better than rolled batts ever can. In Austin homes, where attic framing is rarely uniform and recessed lights, duct runs, and cathedral ceilings create endless nooks, blown in insulation is the go-to solution. We work primarily with Owens Corning fiberglass and GreenFiber cellulose, matching the material to the attic’s existing condition, moisture history, and your budget. Most blown in attic insulation jobs in Austin run between $1,600 and $3,900, depending on square footage, target R-value, and how much old material needs to come out first. You’ll get an exact written number before any work starts.
When It’s the Right Call
If your attic has patchy, thin, or settled insulation, blown in material levels the field. We can blow directly over existing insulation in many cases, which keeps the job faster and less expensive than an Attic Insulation Replacement.
What We Actually Do
We test the existing depth and R-value first, then calculate exactly how many bags of material your attic needs to hit the target. The crew runs a hose from the truck, fills every bay evenly, and documents the finished depth with photos.
Insulation Contractors
Insulation contractors are the people you call when you need insulation installed, removed, or diagnosed, and in Austin the quality gap between contractors is enormous. Some send a salesperson with a glossy binder and a moving quote. Some never show up at all. Woolsey Insulation Austin operates differently: our technicians are background-checked and uniformed, we carry eight leading insulation brands so the recommendation fits your home, and every job runs through the Kingswell Guarantee. Most insulation contractor jobs we handle in Austin run from $800 for a small air-sealing and Attic Insulation Top-Up project to $8,000+ for a full removal, air sealing, and re-insulation on a larger home. You won’t find a price that shifts at the door. You will find a written guarantee included with every installation.
Choosing an Insulation Contractor
Ask whether the price is written and fixed before work begins. Ask whether the crew is background-checked. Ask what happens if the work fails. We answer all three questions the same way, because we put it all in writing.
The Kingswell Guarantee
Every Woolsey job includes a written price, a committed arrival window, a clean job site, a written guarantee, and a free return visit if anything fails within the guarantee period. That’s The Kingswell Way, and it’s been our standard since 2002.
Attic Ventilation
Attic ventilation is the system of intake and exhaust vents that keeps air moving through your attic space, and in the Austin climate it’s the difference between an attic that stays at 115 degrees and one that hits 150. Heat builds fast under a Texas sun, and without proper airflow that heat radiates into your living space and cooks your shingles from underneath. Proper attic ventilation also prevents moisture buildup that leads to mold and rotted decking. We install and balance Attic Baffles & Ventilation Prep as part of our attic insulation services, and most Austin homes benefit from ridge vents, soffit vents, and at least one powered or passive exhaust. Ventilation work in Austin typically costs between $450 and $1,400, depending on vent type and attic size.
Balancing the System
Too little ventilation traps heat and moisture. Too much exhaust without enough intake creates negative pressure that pulls conditioned air from your living space. We measure square footage and existing vent area, then calculate what the attic actually needs.
Signs of a Struggling Attic
Warm ceilings in summer, frost or condensation on the underside of the roof deck in rare cold snaps, and musty smells after rain all point to ventilation trouble. If you feel heat radiating from the ceiling in August, the attic isn’t moving air the way it should.
Radiant Barrier
A radiant barrier is a reflective material, usually aluminum foil laminated to a substrate, installed under the roof deck or on the attic floor to reflect radiant heat before it enters the attic. In Austin, where the sun beats on roofs 250+ days a year, a properly installed radiant barrier can reduce attic temperatures by 20 to 30 degrees. That directly cuts the heat load on your AC system and keeps upstairs rooms noticeably cooler. We install radiant barrier as a complement to insulation, not a replacement for it, because insulation still has to do the heavy lifting once heat gets inside. Radiant barrier installation in Austin typically runs $1,200 to $3,200 depending on attic surface area and whether we install at the roof line or on the floor.
Roof Line vs. Floor
Roof line installation reflects heat before it ever enters the attic, which makes the space dramatically cooler. Floor installation is simpler and costs less, but the attic still absorbs heat above the barrier. We’ll recommend the right approach for your attic’s construction and how you use the space.
Does It Work in Austin?
It works best in hot climates, which makes Austin about as ideal as it gets. The key is continuous coverage and a small air gap, both of which our crews install as standard practice, not as an upcharge.
Attic Cleaning Services
Attic cleaning services address what’s living, dying, and accumulating above your ceiling: dust, debris, old pest nests, blown-in insulation that’s compressed and soiled, and in some cases droppings from squirrels or raccoons. In Austin’s older neighborhoods like Hyde Park, Travis Heights, and Allandale, attics often hold decades of residue that reduces insulation performance and can trigger allergies. We clean the attic before installing new insulation, removing contamination with a high-powered vacuum system and treating affected areas. Attic cleaning in Austin typically runs $500 to $1,200 on its own, or is bundled into insulation removal and replacement at a lower effective cost.
Why Clean Before Insulating
Blowing fresh insulation over debris, dust, and pest waste doesn’t solve the problem, it seals it in. A clean attic gives the new insulation a proper substrate and lets us inspect the full decking for leaks or damage.
What We Remove
We remove old insulation, pest nesting material, dust, and debris with a commercial vacuum system, and we dispose of everything off-site. Then we sanitize the decking and joist bays before any new material goes in.

Attic Mold Removal
Attic mold removal is the process of identifying, eliminating, and preventing mold growth on attic surfaces like roof decking, joists, and insulation. In Austin’s humidity, mold grows in attics with poor ventilation or small roof leaks, and it spreads fast. We treat mold on wood surfaces, remove and replace contaminated insulation, and correct the ventilation or moisture issue that caused it. Because we only handle attic insulation and adjacent services, we focus on the mold that affects your insulation system and the air moving through the home. Attic mold removal in Austin typically costs $1,000 to $3,500, depending on square footage, mold extent, and whether full insulation replacement is needed.
Mold and Insulation
Mold grows on the paper backing of batt insulation and throughout dirty cellulose. Once it reaches the insulation itself, removal and replacement is the only reliable path. Bleach and paint don’t solve the root cause.
The Ventilation Link
Almost every mold case we see traces back to inadequate attic ventilation or a small leak. We treat the mold, then we fix the airflow so it doesn’t come back. A mold treatment without a ventilation fix is a temporary patch, and we don’t do temporary.
Attic Insulation Removal
Attic insulation removal is the process of extracting old, damaged, or contaminated insulation from an attic so that new, clean, properly rated material can take its place. This is a job for professional equipment and breathing protection, not a weekend DIY project. We remove old insulation when it’s soiled by pests, soaked by a roof leak, or settled into a mat that no longer provides meaningful R-value. Austin homes from the 1960s through the 1980s often have insulation that was minimal to begin with and has been trampled flat over decades of AC work, cable installs, and general attic activity. Removal typically runs $1,500 to $4,500 in Austin, depending on attic height, access, and material type.
Full Removal vs. Top-Off
If the existing insulation is dry, structurally sound, and free of contamination, adding new material on top is the most cost-effective approach. If it’s compacted, wet, or riddled with pest waste, full removal is the honest answer, and we’ll tell you which one your attic needs.
The Removal Process
Our crew uses a commercial vacuum system that extracts the old insulation directly into sealed bags in the truck. The attic is then cleaned, inspected, and prepped for new air sealing and insulation in the same visit.
Brands We Service
We install and service insulation from three primary brands in Austin: Owens Corning, GreenFiber, and Demilec. Owens Corning fiberglass is our standard for blown-in and Attic Batt Insulation applications, because it delivers consistent R-value and doesn’t settle the way older fiberglass products do. GreenFiber cellulose is our go-to for homeowners who want a high recycled content material that packs tight and fills irregular spaces. Demilec spray foam is what we use for air sealing applications and hard-to-treat attics.
We also have hands-on experience with insulation from Johns Manville and continue to work on homes that have existing Johns Manville material in place. Whether you have a builder-grade batt from the 1990s or a recent foam job from another contractor, we can assess what’s there, tell you honestly whether it needs to come out or can be built upon, and give you a written number for either path.
Signs You Need a Pro Right Now
- Your upstairs rooms run 8-10 degrees hotter than downstairs. That temperature gap is almost always an attic insulation or ventilation failure. The heat soaking through the ceiling forces your AC to fight all day, and fixing the attic usually closes the gap faster than any HVAC change.
- You can see the tops of the ceiling joists in your attic. If the insulation doesn’t cover the joists, you’re working with roughly R-11 to R-19 in a climate that calls for R-38 or better. You’re paying to cool air that escapes straight through the ceiling.
- Your electric bill jumped without a clear reason. Outdoor temps, thermostat settings, and insulation condition all factor in, but a sudden spike often means insulation has settled or been damaged by pests. We can tell you in one visit.
- You smell something musty or see staining on the ceiling. That’s a moisture problem in the attic, and it rarely fixes itself. Mold, wet insulation, and water-stained drywall compound fast in Austin’s humid months.
- You’ve had squirrels, rats, or raccoons in the attic. Pest activity compresses insulation, tears vapor barriers, and contaminates material with droppings. Fresh insulation over that mess traps the contamination and keeps it in the air you breathe.
Our Process, Step by Step
- 1
The inspection. We walk the attic, measure the existing insulation depth and type, check ventilation, and photograph everything. You’ll see what we see, and we’ll talk through the specifics of your home’s construction.
- 2
The written quote. Before any work starts, you get a fixed price in writing. That’s the number you pay, period. It covers materials, labor, cleanup, and the written guarantee. No door-knock adjustments, no add-ons.
- 3
The prep. We protect the access point, run containment where needed, and stage equipment so the interior of your home stays clean. The crew is uniformed, background-checked, and briefed on your specific job before they arrive.
- 4
The work. We remove old material if needed, air seal the attic floor, install the right insulation at the right depth, and balance ventilation. We use depth markers to document that the R-value we quoted is the R-value you got.
- 5
The walkthrough and paperwork. We show you before-and-after photos, confirm the finished depth, and hand you the written 365-day guarantee. If anything isn’t right within the next year, call and we come back at no charge. A live person answers, 24/7.
How Much Does Attic Insulation Cost in Austin?
A typical attic insulation project in Austin runs between $1,600 and $4,800, depending on attic size, existing insulation condition, and the R-value you’re targeting. Blown-in fiberglass or cellulose starts around $1,600 to $3,900 for a standard 1,500 to 2,500 square foot home. A full insulation removal with air sealing and re-installation runs $2,800 to $6,500, especially if pest contamination or moisture damage is involved. Spray foam jobs run higher, usually $4,000 to $10,000 for a typical attic, but they deliver the highest R-value per inch and seal air gaps as they go. Add-on services like attic cleaning ($500 to $1,200) and mold removal ($1,000 to $3,500) are quoted separately and transparently.
What affects the price? The attic’s accessibility and height, the condition of existing insulation, whether air sealing is needed, the type of material you choose, and any moisture or contamination issues we find. The way to avoid overpaying is to get a written, itemized quote before the work starts and to insist that the number doesn’t move. That’s what we do on every job, no exceptions. Your free estimate includes the inspection, the measurements, the material recommendation, and the exact written price. Call (361) 418-9997 to schedule yours.
