Round Rock's 1990s and 2000s two-story homes were built with bonus rooms over garages and long ductwork runs through vented attics that hit 140 to 160 degrees Fahrenheit on the brutal hundred-degree summer days that define Central Texas. Those attics leak conditioned air, sweat with humidity, and drive electricity bills higher every year. Austin Spray Foam Insulation has been sealing and insulating homes across Round Rock (78664) and the Austin area since 2012, and we know exactly what those attics demand.
Homeowners in Round Rock call us when a bonus room over the garage never cools, when the master bedroom at the back of the house stays hot no matter what the thermostat says, or when the electric bill has simply become unaffordable. We arrive with a clear head, measure what needs to be done, and explain it plainly. No pressure, no fear tactics, just honest work that lasts.
Spray Foam Insulation in Round Rock (78664)
The Round Rock housing stock of the last twenty-five years sits on concrete slabs with two stories and typically a bonus room cantilevered over the garage. That bonus room and the master bedroom beyond it are the hottest spaces in the house because the ductwork and the attic above them are wide open to the Texas sun. The attic itself is vented, which means it exchanges air with the outside, and in summer that air is brutal. Add to it the fact that many of those homes were built with drywall ceilings and minimal or compressed original insulation, and you have a perfect storm of heat gain and air leakage.
Closed-cell spray foam seals those air leaks, stops the heat at the roof deck, and controls humidity that would otherwise condense on the underside of the roof sheathing or drip onto the ductwork below. Open-cell foam works in attics where ventilation is not a concern and where a lower cost per board foot makes sense. We also inject foam into the wall cavities of those two-stories, seal the rim and band joists where the house sits on the slab, and spray the garage ceiling to keep the bonus room above it from inheriting the heat that builds up in an uninsulated garage.
We have been doing this work in Round Rock and across Austin since 2012. Our team is fully insured, and we show up with written estimates that name the R-value and thickness we will install, so you know what you are paying for before we ever touch a spray gun.

How a Job Works in Round Rock
We start with a free on-site assessment. You walk us through the spaces that are uncomfortable, and we climb into the attic, inspect the crawl space or basement if there is one, look at the walls and the rim joists, and measure what we are working with. We ask about your utility bills, about which rooms run hot or cold, and about any moisture or smell you have noticed. Then we give you a written estimate with the R-value, thickness, and total board footage we recommend, and a firm price. No surprises, no upsells.
On the day of the work, we bring our spray rig and our crew. If there is old insulation that is wet, compressed, or fouled, we remove it first. We set up mechanical ventilation in the attic or crawl space to move fumes out while the foam cures. We spray the foam in controlled passes, watching the thickness and the rise, and we document what we have done. We leave your property clean and give you a re-entry window of twenty-four to forty-eight hours before the space can be occupied or used normally. We also brief you on what to expect: a chemical smell that fades quickly, and a slight warmth as the foam cures.
When the work is done, we walk through with you, show you what we have sprayed, and answer any questions. You get a copy of the estimate and the work record. That is it. We are out of your way.
Pricing for spray foam insulation in Round Rock depends on what you are insulating and what condition it is in. An attic top-up on a sound existing base of insulation might run from $1.50 per square foot for open-cell foam, while a full attic spray with removal of old insulation might be higher. Wall and injection foam runs from $2 per square foot. A crawl space starts around $2,500 depending on size and access. Rim and band joist sealing starts at $650. Insulation removal alone runs from $950. The key factors are the total area, the R-value and thickness you need, whether you are using closed-cell or open-cell foam, what has to come out first, and how easy our crew can get to the space. Every job is different, and every estimate reflects what your house actually needs. Call us at (737) 404-4885 for a free estimate. We will measure your space, show you the options, and give you a price in writing before we start.
