West Lake Hills sits on steep limestone lots where the Hill Country drops toward Austin, and your 1960s-through-1980s custom home was built to command the view, not to shed summer heat. Vaulted ceilings, open floor plans, and skylights are beautiful but brutal on a cooling bill when the attic above them hits 150 degrees for months on end.
That is why homeowners in West Lake Hills (78746) call Austin Spray Foam Insulation. Your home needs insulation that matches its architecture, seals the gaps that central air cannot reach, and handles the humidity and temperature swings that come with a steep limestone site and a long Texas summer. We have been serving West Lake Hills and the surrounding Austin area since 2012, and we know exactly what these homes demand.
Spray Foam Insulation in West Lake Hills (78746)
West Lake Hills homes are built on challenging terrain. Your lot likely sits on limestone bedrock with a pier-and-beam foundation or a concrete slab, and your roof is often vaulted or cathedral-style with ductwork and water lines running through an attic that has nowhere to go but up. Summer temperatures in that attic routinely exceed 150 degrees over the course of a hundred-degree day, and the ductwork that cools your bonus room or master suite loses conditioning before it ever reaches the room. Humidity and condensation are constant risks in a sealed attic with no ventilation, especially around ductwork and in the spaces where the roof line meets the wall.
Many West Lake Hills homes also have closed wall cavities with little or no original insulation, and crawl spaces or rim joists that were never sealed. Spray foam closes all of these gaps at once. Closed-cell foam is the right choice for attics and sealed roof decks because it stops air movement, resists moisture, and delivers the R-value you need in a tight space. Open-cell foam works for walls and injection cavities where thickness is not a constraint. Either way, we seal the air leaks that your air conditioner has been fighting all summer.
Our team has been insulating West Lake Hills homes and the Austin area for over a decade. We know the local building code, the thermal barrier and ignition barrier rules that apply to your address, and how to work in a finished home without disrupting your daily life.

How a Job Works in West Lake Hills
We start with a free on-site assessment. We walk your attic, crawl space, or walls, measure the area to be sprayed, check for any moisture or existing insulation that has to come out first, and review what the local building code requires at your address. We give you a written estimate with the R-value and thickness we recommend, the cost per board foot or square foot, and a timeline. No surprises.
On the day of the work, our fully insured crew arrives with the spray equipment and sets up mechanical ventilation. Spray foam requires controlled conditions: we maintain the manufacturer's ratio and drum temperature, apply the foam in passes of the correct thickness, and keep the space ventilated during the cure. If your home is occupied, we establish a clear re-entry window, typically 24 to 48 hours depending on the product and the weather. You stay informed every step of the way.
When the foam has cured, we clean up, remove the temporary ventilation, and walk through the finished space with you. We leave your property clean and your insulation ready to work for the life of the home.
Pricing for spray foam insulation in West Lake Hills depends on what you are doing. An attic foam job typically runs from $1.50 per square foot for open-cell foam on top of existing insulation, to higher costs if the attic is large or has complex geometry or existing insulation that has to be removed first. Wall injection foam for closed cavities starts around $2 per square foot. A crawl space sealed with closed-cell foam on the rim band and floor typically runs $2,500 and up, depending on size and access. Insulation removal, if the old material is damp or fouled, starts at $950. The key variables are the square footage or board footage to cover, the R-value and thickness specified by code, whether you choose open or closed cell, and what has to come out before anything new goes in. We give you a free written estimate at (737) 404-4885 so you know exactly what the job costs before we start.
