Insulation Installation in South Austin, TX
South Austin is one of the most architecturally layered parts of the city — and that layering creates insulation challenges you won’t find anywhere else in the Austin metro. From the pier-and-beam bungalows lining the streets of Bouldin Creek to the aging ranch homes stretching south along Slaughter Creek, the homes here demand a level of local knowledge that generic insulation contractors simply don’t bring to the job. We’re Super Green Insulation Austin, led by Tom Hopkins, and we’ve been solving exactly these problems for South Austin homeowners since 2008. Call us anytime at (866) 434-2901 — we’re close, we’re familiar, and we’re ready.
Why Super Green Insulation Austin Is South Austin’s Preferred Insulation Installation Company
South Austin customers have trusted us with some of the most complex retrofit work in Central Texas — triple-envelope jobs in Travis Heights, full attic replacements in SoCo flip properties, and underfloor systems in Zilker bungalows that hadn’t been touched since the Eisenhower administration. That hands-on familiarity with South Austin’s specific housing stock isn’t something you develop reading a manual; it comes from years of work on these streets.
Our 784 verified reviews average 4.9 out of 5 stars, and a meaningful share of those reviews come directly from South Austin homeowners in zip codes 78704, 78745, and 78748. Customers consistently mention that Tom Hopkins and our crew show up prepared — the right materials already on the truck, no wasted trips, no surprises on the invoice.
We treat South Austin as a priority service area, not an afterthought. When you call (866) 434-2901, you’re not getting routed through a national dispatch center. You’re reaching a team that knows the difference between a 1950s pier-and-beam in Bouldin Creek and a 1985 slab ranch off William Cannon — and that difference shapes everything about how we approach your project.
Our Insulation Installation Services in South Austin
Attic Insulation
Attic insulation is the single highest-impact upgrade most South Austin homeowners can make, and the urgency is real. South Austin sits just east of the Balcones Escarpment in a more humid, lower-elevation air mass, meaning attic temperatures here routinely hit 140°F or higher in a typical July. The inner neighborhoods — particularly those in the 78704 zip running through Bouldin Creek and Travis Heights — are packed with homes where the original attic insulation has settled to an R-value far below the current Texas code minimum of R-38, or is absent entirely. We assess your existing conditions first, remove degraded material when necessary, and bring your attic up to code using premium products like Owens Corning and Johns Manville blown fiberglass or batts, sized precisely to your roof geometry.
Blown-In Insulation
For South Austin’s 1970s–1990s slab-on-grade ranch homes — common throughout 78745 and 78748 — blown-in insulation is often the most practical upgrade because it fills irregular joist bays and attic corners without requiring demolition. We regularly use GreenFiber cellulose and Knauf blown fiberglass for these applications, both of which settle minimally and perform well in South Austin’s humidity swings. Blown-in is also the go-to method for dense-packing hollow wall cavities in the older bungalow stock — a technique that makes a dramatic difference in a home that was built with literally no wall insulation between the studs.
New Construction Insulation
South Austin’s land values have made it one of the most active new-construction and gut-renovation markets in Austin, and we work directly with builders and general contractors on projects throughout the 78704 and 78741 corridors. New construction gives us the rare opportunity to specify the right system from the framing stage — including vapor retarder placement that accounts for South Austin’s coastal-plain humidity profile, something that can’t be retrofitted easily later. We work with Icynene and Demilec open- and closed-cell spray foam systems, CertainTeed batts, and Rockwool for applications requiring enhanced fire or acoustic performance.
Trusted Brands We Service in South Austin
We stock materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber — and because South Austin is a core part of our service territory, we keep these materials on-hand rather than ordering per job. That means faster turnaround for South Austin customers, no waiting on supply lead times, and the ability to match the right product to your specific home type rather than defaulting to whatever’s cheapest or easiest to source. Tom Hopkins selects brands based on real-world performance in Central Texas conditions, not manufacturer incentives.
Common Insulation Installation Problems We See in South Austin Homes
- Open crawl spaces with zero underfloor insulation (78704 bungalows): In Bouldin Creek and Travis Heights, the pier-and-beam crawl spaces typically sit only 18–24 inches off grade with no ground vapor barrier and no floor insulation at all. In summer, radiant heat bakes up through hardwood floors from exposed soil; in a hard freeze — as South Austin residents learned painfully during Winter Storm Uri in February 2021 — that same open crawl space lets pipe temperatures drop to ambient outdoor air, causing catastrophic freeze damage.
- Settled or missing attic insulation in mid-renovation properties: Contractors working South Austin flips frequently pull ceiling drywall and find that the original fiberglass batts have slumped, shifted, or been partially removed by prior HVAC or electrical work and never replaced. What looked like a quick cosmetic renovation turns out to have an attic performing at R-8 instead of R-38.
- Incorrect vapor retarder placement driving condensation: Because South Austin sits in a more humid air mass than the Hill Country to the west, vapor drive moves inward from the exterior during summer. We regularly find vapor barriers installed on the wrong side of the assembly by well-meaning but unfamiliar contractors — a mistake that traps moisture inside wall cavities and accelerates wood rot and mold growth in the older bungalow stock.
- Inadequate attic depth in 1970s–1990s ranch homes: The slab-on-grade ranch homes throughout 78745 and 78748 were often built with shallow roof pitches that physically limit how much blown-in depth you can achieve before hitting the framing. We measure this before quoting so you know exactly what R-value is achievable and whether a secondary air-sealing strategy is needed to compensate.
Pricing for Insulation Installation in South Austin, TX
Here’s what South Austin homeowners can expect to budget in the current market. A typical attic insulation installation in South Austin runs $1,800–$3,500 for a standard 1,200–1,800 sq ft home, depending on existing conditions and whether removal of degraded material is needed first. Blown-in insulation for an attic in the same size range runs $1,400–$2,800. Underfloor spray foam for a pier-and-beam crawl space — which is particularly common in the 78704 zip — typically runs $2,200–$4,500 depending on crawl space accessibility and linear footage of floor area treated. New construction insulation packages are quoted per project and typically fall between $3.50–$6.50 per square foot of conditioned space.

The South Austin Pier-and-Beam Reality: A Scope Unlike Anywhere Else in Austin
This deserves its own section, because it genuinely sets South Austin apart from every other area we serve. The 78704 corridor — running through Bouldin Creek, Travis Heights, and Zilker — is densely packed with 1940s–1960s pier-and-beam bungalows that are being aggressively renovated due to the neighborhood’s cultural cachet and soaring land values. What that means for insulation is this: these homes were built with little to no wall insulation and open crawl spaces with uninsulated floors. A proper retrofit here must address three separate building envelopes at once — the attic, the walls, and the underfloor — a scope that is essentially irrelevant in the slab-on-grade subdivisions that dominate North or Northwest Austin. Our crews working Bouldin Creek and Travis Heights keep both open-cell spray foam and rigid foam board on the truck every day because the underfloor envelope needs to be handled before we ever set up the attic blower. It’s a different job, requiring a different preparation, and it’s one we’ve done hundreds of times in South Austin specifically.

FAQs — Insulation Installation in South Austin
We can typically reach South Austin addresses within one to two business days for an estimate, and we schedule most installation jobs within one week of estimate approval. Because South Austin sits within our core service area — not a distant suburb — we don’t apply travel premiums or push South Austin jobs to the end of the queue. Call (866) 434-2901 and we’ll give you a real availability window, not a vague “a few weeks.”
Yes — we serve all of South Austin, from the inner 78704 neighborhoods of Bouldin Creek, Travis Heights, and SoCo through the farther-south zip codes of 78745, 78748, and 78747, including Slaughter Creek and communities approaching the city’s southern boundary. Wherever you are in South Austin, we handle the full scope of your insulation needs without sub-contracting the work.
Yes — particularly for situations involving freeze-exposed crawl spaces or storm-damaged attics, we prioritize urgent calls from South Austin homeowners. After Winter Storm Uri in 2021, we mobilized quickly across the 78704 zip to address pipe-freeze situations caused directly by uninsulated pier-and-beam crawl spaces, and we maintain that same responsiveness today. Call (866) 434-2901 and explain the urgency — we’ll do our best to get someone out same-day or next-day.
Not inherently — but South Austin pier-and-beam homes often require a larger scope than comparable slab-on-grade homes in suburbs like Round Rock or Cedar Park, which can increase total project cost. The three-envelope problem (attic, walls, and underfloor) that’s common in 78704 bungalows simply represents more material and labor than a single-envelope attic job. Our pricing is transparent, range-based, and discussed in full before any work begins — there are no South Austin-specific surcharges.
Our workmanship warranty covers all South Austin installations for a minimum of five years from the completion date, and most of the manufacturer products we install — including Owens Corning and Johns Manville systems — carry their own separate material warranties. Tom Hopkins stands behind every job personally, and if something isn’t performing as expected within the warranty period, we come back at no charge to assess and correct it.
