WARNING: Do NOT Call Any Austin Spray Foam Insulation Contractors Or A Blown Attic Insulation Contractor Before You Read This.

Why the drastic precautions?

The insulation installer business around Austin Texas is one of a few industries that is not well regulated. This includes: spray foam, cellulose, fiberglass, gutters, removal, radiant barrier, replacement windows, and more. This is especially challenging when working in crawlspaces, attics, and walls. The state of Texas does not require any licensing. The industry has a very low barrier to entry so anyone can call themselves a “professional” with no legitimacy behind the claim.

These are people who come to your house and work on one of the biggest and most important Austin energy savings and comfort systems in your building. The aftermath of their work can be very dangerous and even render your building un-livable. Yes, a bad install can make a building un-inhabitable until you have all the insulation removed, and hauled off in Austin dumpster rentals. If the “pro” fails to install their solution properly, use the equipment correctly, and ensure your family’s health and safety you could be in serious trouble.

What Spray Foam Insulation Companies in Austin Do NOT Want You To Know

It seems like every month there is a new nightmare story in the headlines about crimes being committed. Customers being sold more than they need. Exposes on the Bait-and-Switch Austin insulation companies preying on consumers. Offering deep discount offers to get their foot in the door. Then they perform hard sell tactics on unsuspecting consumers. And they lie about expected savings on utility bills.

When searching online for spray foam insulation in Austin” “crawlspace encapsulation Austin“, “attic insulation Austin” “insulation removal Austin or “replacement windows Austin” you can’t really tell who the great insulation contractors in the Austin area are, or the ones you should avoid. 

Top notch companies try hard to distinguish themselves from the fly-by-night attic insulation scammers. The shady guys use dangerous procedures, hard-sell tactics, and have dishonest employees.

There are over 43 different insulation companies serving the Central Texas area including: Key Insulation, Hinkle, Installed Building Products (IBP), Garland, Cool Insulation, USI Chase (aka Synergy), Austin Contractor Insulation Services, True R Value, Attic Dr, BioTex Foam, Hill Country, FoamIt Now, Payless, Green Collar Operations, and many more!

There are many Austin insulation contractors (and many pest control and conditioned air companies serving Austin and the surrounding area). They will provide a free quote, make confusing, and misleading claims about what they do. It pays to learn some basic insulation facts first. I published the following guide (and 6-BONUS reports) to help you…

Testimonials from Stellrr’s Spray Foam & Blown Insulation Clients in Austin, TX

attic insulation removal with spray foam.png

We highly recommend family owned Stellrr Insulation. They covered [and air sealed] our can/ recessed lights added additional spray foam insulation for us and sealed up our home to save us $$ and keep it cooler and warmer. We were so impressed with their professionalism and their follow up. NO harmful chemicals. We got immediate callbacks and personal meetings. Shawn, Wayne, Shelly & Violet took great care of our family.

The Stellrr team did a stellar job with the install spray foam insulation in our attic. Our home is a single story 3000sf ranch style home and the job took about 3 days to complete. I had measured temperatures on the attic side of the metal roof to be over 130 degrees! I just checked again, and now it’s 75 degrees without air conditioning it! All of my questions were answered in detail and the job went without a hitch. The temperature in the house is much more stable because of the air barrier. The HVAC comes on much less frequently. It’s even quieter inside! We can’t wait to see our lower energy bills. I would absolutely recommend Stellrr to anyone who needs spray insulation.

duct encapsulation and air sealing

Earlier this year, my wife and I hired Stellrr to remove all the spray-in [loose fill fiberglass] insulation from our attic and come back in with deck foam spray [closed cell spray foam insulation on the underside of the roof deck]. Our goal was to resolve an issue with condensation that formed on the 1959 metal ductwork which pooled and created leaks in our ceiling. Our attic is now approximately 10 degrees warmer than the interior of the home.  It’s now summer with temps hitting 100 degrees in central Texas and we could not be happier.  We HIGHLY recommend Stellrr!!  A+++  Thanks very much!!

Stellrr is truly outstanding! The quality of the work merits the very highest of recommendations. I can speak to Stellrr’s skill with both closed cell spray foam insulation and open foam because the scope of work was the application of closed cell foam on the underside of a late 1970s-built pier and beam home [crawlspace], and open cell in the attic. Four-decade-old batt insulation was removed and hauled away. Within 36 hours the humidity level plummeted due to the air and moisture infiltration reduction. On the third day, Stellrr applied closed cell foam to the underside of the home, and within 48 hours the home smelled normal, meaning the air-quality problem was solved. The estimating process was transparent and efficient; the pricing fair (you are paying for excellence); customer service as friendly as could be (Stellrr even brought me back lunch on the first day); and the workmanship first rate, with a rare level of conscientiousness and attention to detail. Great friendly crew. Seriously, don’t spend time shopping around: just select Stellrr Insulation & Spray Foam.

— David P. from Westlake Hills on Yelp

Stellrr did an amazing job on insulating my completely gutted “A” Frame [cathedral ceiling] house. I had some special requests and they didn’t complain, the just foamed it up. After the remodel the electricity bills are 1/2 of what they used to be. Also it is so quiet, I can’t even hear it raining on the roof [because of the spray foam encapsulated attic and roof spray foam insulation in Austin]. The temperature stays very steady and the whole house is always comfortable. Stellrr also [sprayed closed cell foam on] did the ceiling in my car trailer… wow, what a difference the R value makes. Never seems hot in the trailer, even when its 95 degrees outside. Great product and totally worth it. It feels like a new home. I will use them again!

Chris H from Spicewood on Yelp

We have an old repo home that we were in the process of remodeling, not new construction.  As it was on pier and beam the floors [over the crawlspace] were very cold in the winter.  After several calls and getting [insulation] a free estimate from several contractors, Stellr was the company we chose to go with on our existing home.  They were not the absolute cheapest but I had the best feeling after talking with them about our future projects.  They got the [crawlspace closed cell spray foam insulation] work done as promised and we couldn’t be happier.  They did an excellent job and I could whole-heartedly recommend them. Our carbon footprint is significantly reduced.
