Insulation Company in Lakeway, TX
Woolsey Attic Insulation handles attic insulation and spray foam insulation in Lakeway, TX, and the work here looks different than it does in Austin proper. That combination means we spend a lot of time fixing under-insulated attics in older ranch-style homes and dialing in air-sealing on newer two-story builds. Call (361) 418-9997 and we’ll give you a written price before any work starts.
Why Lakeway Homes Are Different
Lakeway started as a lakeside resort community, and a lot of the original houses from the 1960s and 1970s went up with insulation that barely qualifies as insulation by today’s standards. We routinely pull back old batts in neighborhoods like Yaupon Cove and find R-11 fiberglass that’s settled to R-6, covered in decades of hill country dust. The homes around Live Oak Golf Course and along Lakeway Boulevard span everything from original one-story ranch houses to 2010s custom builds, and each era has its own failure pattern. Older homes leak air at the top plate and around recessed lights. Newer builds often have code-minimum fiberglass that checks the box on paper but lets attic temperatures climb past 130 degrees in August.
The terrain matters too. Lakeway’s hills mean wind drives harder across ridge lines, and homes on exposed lots near the lake get hit with moisture that condenses in under-ventilated attics. We see more attic moisture problems in the neighborhoods off Highlands Boulevard than homeowners expect. It’s not just heat. It’s humidity, limestone dust, and the fact that HVAC systems here run ten months a year. All of that lands in the attic first.
Our Main Lakeway Services
Most Lakeway homeowners call us about one of two things: replacing or topping up thermal attic insulation, or sealing the attic with spray foam. Each has its own page with local pricing, what to expect, and the specific problems we see in this market.
Attic Insulation in Lakeway
Blown-in fiberglass or cellulose is the most common fix in Lakeway, especially in the older neighborhoods where attic access is tight and the existing insulation has settled flat. We air-seal first, then blow to the R-value the house actually needs: R-38 to R-60 depending on the year built and how the attic is vented. In a two-story Lakeway home, the upstairs bedrooms are usually eight to ten degrees warmer than downstairs, and most of that heat comes from the attic. Read more on our Attic Insulation in Lakeway page.

Spray Foam Insulation in Lakeway
Open-cell spray foam works well in Lakeway attics where the roofline is complicated: vaulted ceilings, knee walls, skylights, recessed fixtures. It expands to fill gaps and seals the attic as a conditioned space, which changes how the whole house handles humidity. In a lakeside climate like Lakeway’s, that air-sealing matters as much as the R-value. Closed-cell foam has a place too, especially in tight roof assemblies. See Spray Foam Insulation in Lakeway for how both work in this area.

Pricing for Insulation Company in Lakeway, TX
| Service | Typical range in Lakeway |
|---|---|
| Attic insulation removal and replacement | $1,800 – $3,200 |
| Blown-in attic insulation (air-seal + R-38) | $1,400 – $2,600 |
| Air sealing attic floor | $600 – $1,100 |
| Attic radiant barrier | $900 – $1,900 |
| Open-cell spray foam attic (roofline) | $3,500 – $6,500 |

| Knee wall insulation | $700 – $1,500 |
What pushes a Lakeway job toward the top of those ranges is access, not square footage alone. An attic with a tight scuttle, no flooring, and HVAC ductwork crossing every bay takes longer to seal and blow. A wide-open attic over a one-story ranch moves fast. You get a written price before anything starts, every time, no exceptions. That’s the Kingswell Guarantee, and it’s 365 days, in writing, on every job.

FAQs About Insulation Company in Lakeway
Most Lakeway jobs are scheduled within a few days. If you call (361) 418-9997, a live person answers 24/7 and can set a real arrival window, not a vague time range. We don’t use voicemail for scheduling.
Insulation work that stays inside the attic rarely triggers HOA review in Lakeway, since nothing changes on the home’s exterior. If you’re in a community with strict covenants, we’ll note it on the written quote so you’re covered before anything starts.
Almost always. Older Lakeway homes, especially those built before the 1980s, often have R-11 or R-19 attic insulation that was code at the time but is far below what a Texas attic needs. The upstairs comfort difference is noticeable within a day of the job finishing.
If your attic is hot, dusty, or just not doing its job, call Glenn Hartley’s team at Woolsey Attic Insulation: (361) 418-9997. We’ll give you a written price, show up when we say we will, and back the work for 365 days. That’s how the Kingswell Way works in Lakeway.

What Lakeway Customers Say
"Drafty old house that never felt comfortable. After the attic and some air sealing it's a different place. On time, clean, and the quote didn't change. Wish I'd done it years ago."
- Dmitri Kozlov"Insulation job was done well. Scheduling took a little longer than I'd have liked, they were booked out a couple weeks. But once they came it was quick and the house is cozier."
- Felicia Grant"Spray foam in the crawlspace and new attic insulation. They wrote up the whole price and the two jobs came in exactly as quoted. Floors upstairs aren't freezing in the morning anymore."
