Call (325) 246-2929 and we’ll tell you exactly what’s going on in your attic, in plain English, before anyone steps foot in your house.
Why Aspen Attic Insulation Austin Is Cedar Park’s Preferred Spray Foam Insulation Company
Cedar Park homeowners keep calling us back for one simple reason: we write down the name and face of the person coming to your door before they arrive, and we write down the price before a single can of foam gets opened. Garrett Sloane runs our operation, and he set the protocol from day one: every tech is background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. If the person at your door doesn’t match the photo we sent, the visit is free. That’s the Threshold Verified standard, and it applies to every job in Cedar Park, no exceptions.
We’ve crawled through hundreds of Cedar Park attics, including plenty in the Twin Creeks and Forest Oaks areas. What we find over and over is the same: builder-grade fiberglass batts that were never enough for a Texas attic, compressed to R-19 or worse within a decade. Our reviews from Cedar Park customers regularly mention two things: the tech showed up when we said he would, and the final bill matched the written estimate. We answer the phone with a live person 24/7, even on weekends. The dispatch and scheduling happens from our Austin office, but the crews live and work right here in the Cedar Park area. That means we’re not fighting traffic from across the metro when you need us.

Closed Cell Spray Foam Insulation in Cedar Park
Closed cell spray foam insulation in Cedar Park is the retrofit we recommend most often for two-story homes built between 1995 and 2015, because it solves the problem that extra fiberglass never will: it air-seals and insulates in a single pass, and it doesn’t settle. Closed-cell foam goes on as a liquid and expands to about an inch of rigid, structural foam with an R-value of roughly 6.5 to 7 per inch. In a Cedar Park vented attic, we typically spray 2 to 3 inches on the roofline and gable ends, which brings your attic into the building envelope and drops that upstairs-downstairs temperature split to within a couple degrees. Cost for a closed-cell roofline retrofit in Cedar Park usually runs $5.50 to $7.00 per square foot of treated area. Jobs in Buttercup Creek, where many homes have shallow roof pitches and tight access, often land at the higher end.
Rim Joist Sealing for Two-Story Cedar Park Homes
Every two-story house in Cedar Park has a rim joist, and in homes built before 2010, it’s rarely sealed. That’s the band of wood where the first-floor ceiling meets the second-floor walls. Gaps there let hot, humid August air pour into the house cavities. We spray closed-cell foam in the rim joist bays, usually 2 inches, at a cost of $3.50 to $5.00 per linear foot. It’s a half-day job in most Cedar Park homes, and it changes the comfort equation on the second floor almost immediately.
When Fiberglass Batts Have Already Failed
If your Cedar Park attic still has the original fiberglass batts, chances are they’re doing about half their rated job. Fiberglass R-30 batts settle to R-19 or below within eight to twelve years in Texas attic heat, especially along the outer bays where airflow compresses them. Closed-cell spray foam doesn’t settle. It bonds to the roof deck and stays put. For homes in Forest Oaks or around Cedar Park High School where we see excessive dust and temperature swings, closed-cell retrofit is the default fix, not the upgrade option.
Open Cell Spray Foam in Cedar Park
Open cell spray foam in Cedar Park costs less per inch than closed-cell and does one thing extremely well: it fills every gap that fiberglass can’t. Open-cell expands to roughly 100 times its liquid volume, creating a spongy, breathable layer that deadens sound and seals the small leaks that drive up air conditioning bills. We recommend it for Cedar Park single-story homes where the attic is accessible and you want maximum air sealing per dollar, typically sprayed to a depth of 5 to 6 inches on the attic floor for around $2.50 to $3.75 per square foot. For a 2,000-square-foot attic floor, that’s roughly $5,000 to $7,500 completed.
Garage Ceiling and Bonus Room Applications
Plenty of Cedar Park homes have a bonus room or media room built over the garage. In July, those rooms bake because the garage ceiling below was never insulated properly, if at all. Open-cell foam sprayed to 5.5 inches on the garage ceiling and the underside of the bonus room floor typically runs $2.75 to $3.50 per square foot. We usually finish this in a single afternoon, and the temperature difference in the room above is noticeable that same evening.
Sound Dampening for Busy Cedar Park Streets
If your house sits on Ronald Reagan Boulevard, Whitestone Boulevard, or any of the busier cut-throughs near Lakeline Mall, you already know the road noise. Open-cell foam on exterior walls and the attic knee walls cuts transmitted noise noticeably. We use Demilec and Icynene open-cell products, both proven in Central Texas heat and humidity. For a typical master bedroom wall, expect $1,200 to $2,400 depending on square footage and access.
Our Spray Foam Insulation crews handle everything from small rim joist jobs to full attic conversions in Cedar Park, with the same written-price and written-guarantee standards on every single job.
Trusted Brands We Service in Cedar Park
We keep our Cedar Park trucks stocked with spray foam systems from Demilec, Icynene, and Owens Corning, plus fiberglass and cellulose materials from GreenFiber and Johns Manville for comparison jobs. That matters because a Ranch at Brushy Creek home with a failing radiant barrier needs something different than a 1990s Buttercup Creek tract house with settling batts. We match the product to the problem, not the other way around. And because our Austin office coordinates local Cedar Park inventory, we rarely have to reschedule for a materials run. When we say we’ll be there Tuesday, we’re there Tuesday with the right foam on the truck.
Common Spray Foam Insulation Problems We See in Cedar Park Homes
- Settled builder-grade fiberglass: In hundreds of Cedar Park homes built between 1995 and 2010, the original R-30 batts have compressed to R-19 or worse. That’s the single biggest reason your second floor is 10 to 15 degrees hotter than your first in July. Closed-cell retrofit fixes it in one trip.
- Radiant barrier condensation: Many Cedar Park builders stapled reflective foil under the rafters, then homeowners added spray foam later. When humid nighttime air hits that foil-to-foam interface, condensation forms at the eaves in August, and we’ve pulled moldy drywall from those corners. The fix is a proper air seal before foam, never foam over foil without addressing airflow.
- Shallow roof pitch heat trapping: Cedar Park’s spec houses often have 4/12 or shallower roofs with vented attics. In a 100°F summer, the attic air hits 140°F plus, and if your duct runs through that heat, your AC works harder for nothing. Spray foam on the roofline moves the thermal boundary to the roof deck, which is where it should have been all along.
- Thermal cycling on south-facing roofs: South-facing roof decks in Cedar Park get hammered with direct sun, cycling from 140°F daytime to 75°F at night. That thermal expansion and contraction degrades improperly applied sprayed foam faster than almost anything else. We use closed-cell Demilec products with the right surface prep and UV protection on those exposures, so the foam doesn’t crack or peel within a few seasons.
Pricing for Spray Foam Insulation in Cedar Park, TX

FAQs About Spray Foam Insulation in Cedar Park
Because the houses were built with R-30 fiberglass batts in vented attics, and those batts settle to R-19 or worse within ten years of Texas heat. Adding more fiberglass does nothing to stop the air leakage through the top plates, can lights, and chase openings. Closed-cell spray foam air-seals and insulates in one pass, and it doesn’t settle. That’s why it’s the right retrofit for most Cedar Park homes built in the 2005 to 2015 wave. For a flat price on your specific attic, call (325) 246-2929 and we’ll walk you through it.
No, and here’s why. Radiant barrier foil creates a condensation surface when spray foam is applied on top of it, especially during humid August nights in Cedar Park. Moisture collects at the foil-to-foam interface and mold follows at the eaves. The correct approach is to remove or cut back the foil in the areas being sprayed, air-seal the top plates and penetrations, then apply the foam directly to the roof deck or sheathing. We do this routinely in Ranch at Brushy Creek and Twin Creeks homes where radiant barrier is common.
Most Buttercup Creek two-story retrofits take one full day, sometimes spilling into a second morning if we’re also removing old insulation. We recommend you be out of the house during the spraying and for about 2 to 4 hours after, because the foam off-gases briefly. By evening, the upstairs temperature shift is already noticeable. We always confirm the exact timeline in your written estimate before we start.
Cedar Park falls under the 2015 IRC energy code as adopted by the city, which calls for R-38 in vented attics. When you convert to an unvented, spray-foamed attic, the code allows R-20 continuous on the roofline, which 3 inches of closed-cell foam achieves comfortably. We spray to meet or exceed the code requirement on every job, and the writing is in your estimate. For the code specifics on your home’s roof pitch and framing, call (325) 246-2929 and we’ll explain it in plain terms.
Yes, usually by a noticeable margin. In 1990s Cedar Park tract homes, the duct runs live in the attic, where air temperatures hit 140°F in July. When you spray foam the roofline, the attic drops to within a few degrees of the house interior, so your air handler isn’t pulling 140-degree air through leaky return ducts. Most Cedar Park homeowners see a 15 to 25 percent drop in cooling load after a closed-cell roofline retrofit, and that translates directly into lower electric bills. We can point you to specific before-and-after numbers from our Cedar Park jobs when we give your estimate.
