Lakeway sits on the limestone slopes above Lake Travis with vaulted ceilings, large homes on steep lots, and attics that bake in the Texas sun. These aren't modest ranch homes with standard pitched roofs and crawl spaces. They're substantial properties with complex roof lines, cathedral ceilings, and attics that routinely hit 140 to 160 degrees Fahrenheit on the long string of 100-degree summer days that run from June through September.
When your cooling bills climb past reason, or a bonus room over the garage never reaches the thermostat setting, or you walk into the attic and find compressed, damp insulation that's been robbing you of comfort and efficiency for years, that's when homeowners in Lakeway call Austin Spray Foam Insulation. We've been serving the Austin area and the Hill Country since 2012, and we know exactly what spray foam and air sealing can do for a home built the way yours is built.
Spray Foam Insulation in Lakeway (78734)
Lakeway homes are built on limestone bedrock with vaulted ceilings that follow steep roof lines. The attic space is often tight and irregular, the ductwork runs through it uninsulated, and the attic itself becomes a furnace in summer and a cold zone in winter. The walls in many Lakeway homes were built with empty cavities between the exterior stone or limestone veneer and the interior drywall. That cavity space is where heat leaks out in winter and where conditioned air escapes in summer. Crawl spaces under portions of the home, where they exist, collect humidity and condensation from the limestone substrate below. The rim joists and band joists where the floor system meets the exterior walls are often uninsulated or poorly sealed.
Our team has sealed attics, injected foam into closed wall cavities, sprayed crawl spaces, and air-sealed rim joists in homes throughout Lakeway and the surrounding Austin area. We understand the access challenges in a vaulted attic, the importance of getting the thickness and R-value right for your climate, and the need to remove and replace old, compressed, or moisture-damaged insulation before any new foam goes in. We're fully insured, and we deliver a written estimate with R-value and thickness specifications before any work begins.

How a Job Works in Lakeway
We start with a free on-site assessment. You walk us through the attic, the walls you want to insulate, the crawl space, or the rim joists. We take measurements, note what insulation is already there, check for moisture or damage, and explain what spray foam can do and what it will cost. You get a written estimate with the R-value and thickness we're specifying, the type of foam (open or closed cell), and the total price. No surprises.
On the day of the work, our team sets up mechanical ventilation in the attic or the space being sprayed. If old insulation has to come out first, we remove it and haul it away. We spray the foam to the thickness and coverage specified in your estimate, control the ratio and temperature of the material, and make sure the application meets code. We then allow the proper cure time before re-entry. For most residential spray foam work in an occupied home, that's twenty-four to forty-eight hours. You'll smell the material during cure and for a short time after. That smell fades as the foam fully cures.
When the work is done, we clean up the space, remove our equipment, and walk through the finished job with you. Your property is left clean and ready to use.
Pricing for spray foam insulation in Lakeway depends on the area to be covered, the R-value and thickness you need, whether you're using open or closed cell foam, and what has to be removed or prepared first. An attic foam job in a Lakeway home typically runs from $1.50 per square foot for open cell to $1.20 per board foot for closed cell, depending on the thickness required by code and your comfort goals. Wall injection foam for closed cavities starts at $2 per square foot. If you have a crawl space that needs sealing and insulation, budget from $2,500. Rim and band joist sealing runs from $650. If old insulation has to come out first, add $950 and up for removal. The best way to know what your specific job will cost is to call us at (737) 404-4885 for a free estimate. We'll measure the space, assess what's already there, and give you a firm price in writing.
