About Austin

Austin is the capital city of the U.S. state of Texas, as well as the seat and largest city of Travis County, with portions extending into Hays and Williamson counties. Incorporated on December 27, 1839, it is the 11th-most-populous city in the United States, the fourth-most-populous city in Texas, the second-most-populous state capital city, and the most populous state capital that is not also the most populous city in its state. It has been one of the fastest growing large cities in the United States since 2010. Downtown Austin and Downtown San Antonio are approximately 80 miles (129 km) apart, and both fall along the Interstate 35 corridor. Some observers believe that the two regions may some day form a new "metroplex" similar to Dallas and Fort Worth.

I had a superb experience with Stellrr. They helped me rip out the insulation from my 1962 house and spray foam two large attics. Shawn and his team were amazing in every way. They fitted me into their schedule at very short notice as my wife was having breathing problems due to our old, dirty insulation. Dennis and his crew worked incredibly hard to take out the insulation from an overheated narrow attic. At every stage, they went beyond my expectations, helping me take out some old ducting and making sure everything was vented correctly. The spray foam process was equally efficient and it took down our attic temperatures by at least 20 degrees from massively overheated to basically the same temperature as the main house. Stellrr promises to fix problematic houses and they certainly did this with mine. Prior to the spray foam, the HVAC struggled to cool the house, now it does so with ease and we barely need the heating as the spray foam keeps the house within a narrow band of temperatures. This was the best investment we could have made and Shawn and his team delivered far beyond their promises. This is a family business and they were a pleasure to deal with at every turn. I cannot recommend them highly enough. We shopped around and consulted with multiple insulation companies. We feel very fortunate we went with Stellrr and we couldn’t be happier with their work.

Stellrr insulated the crawl space in two of my properties today. They were extremely professional and I was very happy with their responsiveness and service. I had 3 separate estimates, they were all pretty close but I liked these guys the best. Their estimate was turned around same day and the work was completed a couple of days later. They did a super job. I highly recommend this crew!
