GreenFiber Insulation in East Austin, TX | Super Green Insulation Austin

Tom Hopkins and our crew are ready to help. Call us today at (866) 434-2901 to schedule your assessment.
Why East Austin Residents Choose Us for GreenFiber Service
East Austin is not a one-size-fits-all market, and our team knows it. Tom Hopkins has spent 16-plus years working on Austin homes across every era of construction, and a significant portion of that time has been spent in East Austin ZIP codes — 78702, 78722, 78723, and the surrounding corridors. We’re factory-trained on GreenFiber’s full product line, we carry compatible equipment calibrated for the dense-pack densities these older homes require, and we don’t subcontract the work. Our 784 verified reviews averaging 4.9 out of 5 stars reflect a team that shows up prepared, explains what we’re doing, and leaves the job cleaner than we found it.
We also want to be straightforward: Super Green Insulation Austin is an independent service provider. We are not affiliated with or endorsed by GreenFiber’s manufacturer — we simply install and service GreenFiber products with the same standards any authorized professional would apply.
The East Austin Insulation Challenge Nobody Else Talks About
Drive through Cherrywood or down East 6th on any given weekday and you’ll spot at least a handful of bungalows mid-renovation — windows propped open, dumpsters in the driveway, original hardwood floors stacked on the porch. East Austin’s gentrification wave has created a retrofit demand unlike anything happening in Northwest Austin or the newer subdivisions east of 183. The homes concentrated in Cherrywood, Govalle, and the streets radiating off East 6th were built between roughly 1920 and 1955, at a time when mechanical cooling was a luxury and wall insulation was essentially not a consideration.
Here’s the challenge those flippers and long-term owners face: the original plaster walls and hardwood floors that drive resale value in East Austin are the same features that make a standard batt retrofit impossible. You can’t pull walls without demolishing what makes the house worth buying. That means the only practical, code-viable path is drilling through the exterior sheathing and dense-packing GreenFiber cellulose directly into the wall cavities from outside — a technique our crew performs routinely on East Austin jobs but that many Austin insulation companies rarely do at the volume this neighborhood demands. We patch, prime, and match the exterior finish when we’re done.
The floor system is the other vulnerability that February 2021 made impossible to ignore. East Austin’s pier-and-beam bungalows sit above vented crawl spaces that, in most cases, have never had a single inch of floor insulation. During the 2021 freeze, that gap allowed pipe-burst temperatures to develop directly beneath occupied homes. We now include floor-system assessment in every East Austin job estimate — because an attic upgrade that ignores the floor is only solving half the problem.
Common GreenFiber Insulation Problems We Solve in East Austin
- Attic R-value collapse in aging bungalows: East Austin’s Climate Zone 2 designation means attic temperatures routinely exceed 140°F in July, and many pre-1960 homes in Govalle and along the East 6th corridor still carry the original two to three inches of settled cellulose or no insulation at all. We bring attic assemblies up to current IECC R-38 minimums using GreenFiber blown-in cellulose, often pairing the upgrade with a radiant barrier to cut radiant heat load before it reaches your living space.
- Zero wall insulation in plaster-wall construction: Homes in the Cherrywood and Plaza Saltillo area built before 1950 almost universally have empty two-by-four wall cavities behind intact plaster — a thermal weakness that no amount of attic work can fully compensate for. GreenFiber’s dense-pack cellulose, installed through exterior drill-and-fill, fills those cavities completely without disturbing interior finishes.
- Uninsulated pier-and-beam floor systems: Suspended wood floors over open crawl spaces lose enormous amounts of conditioned air year-round and were proven catastrophically vulnerable during the 2021 freeze event. We install GreenFiber batts or blown product between floor joists, improving both thermal performance and the freeze resilience of plumbing that runs under East Austin homes.
- Air-sealing failures at penetrations and rim joists: Older East Austin construction was built before air-sealing was a code concept, leaving gaps around plumbing, electrical, and HVAC penetrations that defeat even a well-insulated assembly. Our crew addresses these points during every GreenFiber installation, because insulation without air-sealing in Austin’s humid climate is money left on the table.

Questions East Austin Homeowners Ask Us Most
What does GreenFiber insulation installation typically cost in East Austin?
Attic blown-in GreenFiber in East Austin typically runs between $1.20 and $1.80 per square foot of attic floor area at current labor and material rates, putting a common 1,200-square-foot bungalow attic in the $1,440–$2,160 range before any Austin Energy rebate. Dense-pack wall retrofits — the most common job type we do in Cherrywood and East 6th — cost more per square foot of wall area because of the exterior drill-and-patch labor, typically landing between $2.50 and $4.00 per square foot of wall depending on sheathing type and patch complexity. Floor system insulation on pier-and-beam homes in the 78702 and 78721 ZIP codes generally runs $1.50 to $2.25 per square foot of floor area. These are East Austin market ranges as of 2025–2026; your exact number depends on access, existing material removal, and scope. We provide itemized written estimates at no charge.
Will dense-pack cellulose damage my original plaster walls?
Done correctly, no — and East Austin homes are where we do this work most often. The drill-and-fill process goes through the exterior sheathing, not the interior plaster. We use a fill tube and controlled pressure to pack the cavity without over-pressurizing, then plug and patch each hole from outside. Your plaster ceilings and walls stay untouched, which is exactly why this method exists: it was developed for occupied historic homes where interior demolition isn’t an option.
Does East Austin qualify for Austin Energy insulation rebates?
Yes. Austin Energy’s Home Performance with ENERGY STAR program offers rebates on qualifying attic insulation upgrades in East Austin ZIP codes, and GreenFiber products meet the material requirements. The rebate amount varies based on current R-value and the improvement achieved. We pull current rebate schedules before every job and walk you through the paperwork — it’s part of the service, not an add-on.
