Why East Austin Residents Choose Us for Demilec Service
Tom Hopkins has led Super Green Insulation Austin for over 16 years, and a significant share of that work has been right here in serving East Austin, TX — inside the tight crawl spaces of Govalle bungalows, above the plaster ceilings of East 6th cottages, and throughout Mueller’s newer construction. Our technicians are trained specifically on Demilec product lines, including Heatlok and Sealection formulations, so we’re not guessing at mix ratios or application depths.
We’ve earned 784 verified reviews averaging 4.9 out of 5 stars — not by being the cheapest crew, but by showing up on time, explaining what we’re doing and why, and leaving your original hardwood floors and plaster walls exactly as we found them. As an independent Demilec sales & service provider, we’re not manufacturer-affiliated, which means our recommendations are driven by your home’s actual needs, not a sales quota.
Common Demilec Insulation Problems We Solve in East Austin
- Attic thermal failure in aging bungalows: East Austin’s dark, low-slope rooftops push attic temperatures past 140°F on a typical July afternoon. Demilec Heatlok closed-cell spray foam applied to the roofline — combined with a radiant barrier — is the most effective single upgrade we perform on the 1920s–1950s housing stock concentrated in Cherrywood and East 6th, dropping attic temps by 30–40°F and taking real pressure off the HVAC system.
- Completely uninsulated floor cavities on pier-and-beam foundations: The February 2021 freeze turned East Austin’s vented crawl spaces into a liability — pipes burst in homes that had never had a single inch of insulation beneath the floor deck. We install Demilec Sealection 500 open-cell foam or blown insulation between the floor joists, sealing that underfloor air gap and dramatically reducing both winter heat loss and the risk of pipe damage during the next hard freeze.
- Wall cavities inaccessible from the interior: In East Austin’s flip and renovation market, preserving original plaster walls and hardwood floors is a deliberate design decision that adds resale value — but it makes standard batt replacement impossible without demolition. We solve this by drilling through the exterior sheathing from outside and dense-packing Demilec-compatible blown insulation directly into the wall cavity, a labor-intensive technique that’s become standard practice on East Austin retrofit jobs at a volume we rarely see in Austin’s newer suburban corridors.
- Inadequate air sealing at rim joists and sill plates: Pier-and-beam construction leaves long runs of rim joist exposed to the crawl space atmosphere, and on East Austin homes built before 1960, that connection between foundation and framing is almost always unaddressed. Demilec closed-cell foam applied to the rim joist band provides both insulation value and a true air barrier — two functions that fiberglass batts, commonly left there by previous owners, simply cannot deliver.
