CertainTeed Insulation in South Austin, TX | Super Green Insulation Austin
South Austin’s housing stock is unlike anywhere else in the metro — and getting CertainTeed insulation right here takes more than a generic install crew. At Super Green Insulation Austin, Tom Hopkins and our team have spent 16+ years diagnosing and installing insulation across South Austin’s pier-and-beam bungalows, mid-century ranches, and everything in between. Ready to stop sending your energy bill through the roof? Call us at (866) 434-2901 — we’d love to talk through what your home actually needs.
Why South Austin Residents Choose Us for CertainTeed Service
We’re CertainTeed-trained installers who live and work in this part of Austin — not a regional franchise dispatched from Round Rock. Tom Hopkins has led our crew since the beginning, and our 784 verified reviews averaging 4.9 out of 5 stars reflect the kind of work we do on streets you’d recognize. We stock CertainTeed products locally, so there’s no waiting on freight to start your project. When you call (866) 434-2901, you’re talking to people who know the difference between a 78704 pier-and-beam crawl space and a 78748 slab ranch — and who bring the right products and approach for each.
As an independent CertainTeed service provider, Super Green Insulation Austin is not affiliated with CertainTeed’s corporate offices. What we are is a team that has chosen CertainTeed as our benchmark brand because its product performance holds up in South Austin’s brutal summer heat and increasingly unpredictable winter cold snaps — you can learn more about our CertainTeed services and why we rely on this product line.
Common CertainTeed Insulation Problems We Solve in South Austin
- Settled or absent attic insulation in older bungalows: In Bouldin Creek and Travis Heights, we regularly find attics where original fiberglass batts have compressed to less than half their rated thickness over 60-plus years, leaving R-values far below the current Texas code floor of R-38. CertainTeed’s InsulSafe SP blown fiberglass lets us reach proper depth even in tight, low-pitch attic decks without disturbing original ceiling plaster.
- Uninsulated underfloor cavities on pier-and-beam foundations: The 18-to-24-inch crawl spaces under Zilker and SoCo bungalows are one of South Austin’s most persistent energy problems — exposed soil radiates heat upward in July and turns into a pipe-freezing wind tunnel during a hard freeze like Uri in February 2021. We use CertainTeed-compatible open-cell spray foam and rigid board to seal this envelope before we ever look at the attic.
- Hollow wall cavities with no insulation: Many 1940s–1960s wood-frame homes in the 78704 corridor were built with structural walls and nothing else — no batt, no blown material, no vapor retarder. South Austin’s position east of the Balcones Escarpment means this area sits in a more humid air mass than Northwest Austin, making vapor-drive condensation a real risk if the retrofit isn’t sequenced and detailed correctly.
- Degraded original batts in 1970s–1990s slab homes: Farther south in 78745 and 78748, we consistently find original fiberglass batts in ranch-home attics that have settled, moisture-wicked, or been disturbed by HVAC work over the decades. CertainTeed’s CertaSpray and its blown-in product lines allow us to encapsulate or replace degraded material cleanly, restoring the thermal barrier without a full gut of the attic floor.
South Austin’s Pier-and-Beam Challenge: Three Envelopes at Once
Here’s something most insulation companies won’t tell you upfront: if you own a bungalow in the 78704 corridor — think Bouldin Creek, Travis Heights, or close-in Zilker — a proper insulation retrofit means addressing three separate thermal envelopes. The attic, the walls, and the underfloor all need work, because all three were built with essentially nothing. That’s a scope that simply doesn’t come up in the slab-on-grade subdivisions that dominate North and Northwest Austin, and it’s why you want a crew that has done this specific job dozens of times, not one that mostly does new-construction slab installs.
South Austin’s climate compounds the urgency. Attic temperatures here routinely exceed 140°F in summer — we’ve measured it ourselves on jobs near Slaughter Creek — while elevated humidity on the coastal-plain side of the escarpment creates condensation risk if vapor retarders are placed on the wrong side of the assembly. Tom Hopkins trains every installer on our team to sequence the work correctly: underfloor first, walls second, attic last, with vapor retarder placement driven by the specific wall and roof assembly we find on site.
This is why our trucks working our South Austin service area keep both open-cell spray foam rigs and rigid foam board loaded at the same time. A crawl space on a Bouldin Creek block might need spray foam to seal rim joists and rigid board on the floor deck — and we want to make that call on-site, not after a second supply run.
What Does CertainTeed Insulation Service Cost in South Austin?
South Austin pricing reflects the reality of older, more complex housing stock. Here’s a realistic range based on the jobs we actually run in this market:
- Attic blown-in insulation (CertainTeed InsulSafe SP), 1,000–1,500 sq ft: typically $1,200–$2,200 depending on current depth and access.
- Underfloor insulation on pier-and-beam (spray foam or rigid board), per linear foot of crawl space perimeter: typically $8–$14 per linear foot for a standard 18-to-24-inch clearance crawl space.
- Wall cavity blown-in on a 1,000 sq ft bungalow (dense-pack method): typically $2,800–$4,500 depending on exterior finish type and number of penetrations required.
- Full three-envelope retrofit on a mid-size 78704 bungalow: most projects land between $6,500 and $11,000 total — a range that reflects the true scope of the work, not a stripped-down attic-only quote.
These are South Austin market figures, and for projects that also involve moisture or pest damage we can pair the insulation work with South Austin Attic & Crawl Space Restoration to address everything in one visit. Every job gets a detailed on-site estimate before any work begins. Call (866) 434-2901 to schedule yours.

Frequently Asked Questions About CertainTeed Insulation in South Austin
Yes — CertainTeed’s blown-in and spray foam systems are specifically well-suited to retrofit work on older pier-and-beam homes because they conform to irregular framing and fill cavities that cut batts can’t reach. In South Austin’s 78704 corridor, where wall framing from the 1940s rarely holds a consistent stud bay, blown dense-pack is often the only practical option, and CertainTeed’s InsulSafe product line performs reliably in this application.
Most single-story bungalows in Bouldin Creek or Travis Heights — typically 900 to 1,400 square feet — take one to two full days if we’re addressing all three envelopes. Attic-only jobs are usually completed the same day we start. We’ll give you a specific timeline during the on-site estimate so you can plan accordingly.
City of Austin does not typically require a building permit for insulation-only work, but if your project involves spray foam in an unvented attic assembly — which changes the building’s mechanical ventilation requirements — we walk you through the applicable residential code review before the job starts. We’re familiar with how Austin Energy’s rebate programs intersect with this work, and we’ll flag any documentation you’ll need.
