Bee Cave sits high on the limestone hills west of Austin with some of the largest new homes in the region, and nearly every one of them specs a sealed attic from the first drawing. The vaulted ceilings, the steep lots, and the long summers that push attic temperatures to 140 degrees or higher make spray foam insulation and air sealing the difference between a home that cools predictably and one where the bonus room or the master bedroom never quite gets comfortable.
Austin Spray Foam Insulation has been serving Bee Cave and the surrounding Austin area since 2012. We understand the construction of homes in 78738: the way ductwork and water lines run through those sealed attics, how condensation can form on metal building roofs when the outside humidity climbs, and why closed-cell foam stops the sweat before it starts. When a homeowner in Bee Cave calls us, they know we have already sprayed the house down the street.
Spray Foam Insulation in Bee Cave (78738)
The homes in Bee Cave are built to last and built to perform. Most sit on concrete slabs or on pier-and-beam foundations with no basements, and the attics above them are sealed from the start. That sealed attic has to breathe through the foam itself and through the air sealing around every duct penetration, every electrical chase, and every rim joist. If the foam is not sprayed to the right thickness with the right R-value and the right ratio, or if the air sealing is incomplete, you end up with condensation dripping off the underside of the roof deck on a humid morning in June, or a damp spot that spreads through the insulation over the course of a summer.
We also see a lot of new construction in Bee Cave where the builder has called for closed-cell foam on the roof deck and open-cell in the walls, or where a homeowner is adding a metal building or a barndominium and needs the foam to stop the thermal bridging through the steel. We have been doing this work in the Austin area for over a decade, and we know what the building code requires at your address and how to get it inspected.

How a Job Works in Bee Cave
We start with a free on-site assessment. We walk through your attic, your crawl space, or the walls you want to insulate. We look at what is already there, check for moisture or damage, and talk through what has to happen before we spray. If old insulation has to come out, we price that separately and schedule it ahead of time so the substrate is clean and dry. We give you a written estimate with the R-value and the thickness we are specifying, so you know exactly what you are getting.
On the day of the work, we set up mechanical ventilation in the space being sprayed. We control the foam application carefully, building thickness in multiple passes and holding the manufacturer ratio and drum temperature steady. Once the foam is down, we clean up completely and walk through with you. We also give you a re-entry window, typically twenty-four to forty-eight hours, before you move back into the space or turn on the HVAC. If you are living in the house while we work, we coordinate the timing and make sure you have the information you need.
Pricing for spray foam in Bee Cave depends on what you are insulating and what has to be removed first. A typical attic foam job, starting from a clean substrate, runs from $1.50 per square foot and up. Wall injection foam for closed cavities starts around $2 per square foot. Crawl space foam starts at $2,500 and scales with the square footage and the thickness required. If you have old, compressed, or rodent-fouled insulation that has to come out first, insulation removal starts at $950 and replacement starts at $2,800. Closed-cell foam, which stops vapor and is often required on sealed roof decks, starts at $1.20 per board foot. Open-cell foam, which is more affordable and breathes, starts at $0.55 per board foot. The key factors are the area to cover, the R-value and thickness your code requires, whether you need closed or open cell, and what substrate preparation is needed.
