Posted on lucia2025-10-03Trustindex verifies that the original source of the review is Google. Sterll did an amazing job cleaning out our attic. They removed all the old insulation and rodent waste thoroughly, then installed spray foam insulation that has completely transformed the space. Afterward, I sealed the attic, which will help lower our energy bills and keep the temperature stable. What impressed me most was how clean and non-toxic the process was, they left the air fresh and the entire area spotless. The team was professional, efficient, and detail-oriented from start to finish. Highly recommend Sterll for anyone looking to clean, sanitize, and insulate their attic properly!Posted on Erica Ingier2025-09-12Trustindex verifies that the original source of the review is Google. Stellrr insulation is running a top notch business. We are very happy with the results of our project, most importantly, but our communications with Pickle and Wayne were timely, thorough, and overall great. Their timeline was also excellent, which isn’t always the case with home improvement projects. From the time they quoted us to the time getting the job done was speedy. We are happy with their work and appreciative. Erica I.Posted on Roland Merz2025-08-06Trustindex verifies that the original source of the review is Google. I want to thank Wayne and Angel for their quick response in helping us out. We were doing a construction project on our student center in San Marcos Tx. and found out that we needed to have a dumpster on site before we could proceed. I made a call to Wayne with dumpstersaurus dumpsters and explained my situation. He was quick to respond and had me a dumpster at the construction site the same day saving us from having the project shut down. Not only did he get it there the same day but the price was very fair and service was very friendly. In today’s business world it was very refreshing to have a company that was trustworthy, quick to respond with same day friendly service, and a very fair price, If you are needing a dumpster I highly recommend dumptersarus dumpsters.

The owner, Wayne, is awesome too - thanks for your extra help, Wayne!Posted on Laila2025-04-08Trustindex verifies that the original source of the review is Google. This is an amazing company! I highly recommend. Stellr has been great to work with. Everyone we were in contact with has been super friendly, polite, and professional. They take the time to explain all of the options for your attic and pricing is straightforward. Sheldon worked with us and he was always so helpful and professional. The two gentleman that came to do the insulation were very hardworking, courteous, and finished ahead of schedule. One of the men even helped bring in a heavy delivery for me- even though he had a huge day of work ahead for him. (I forgot his name, but Stellr knows- because I let them know how impressed I was with his help). The owner Wayne and his wife are wonderful to work with and made sure everything went smoothly. Give these guys a call. Truly excellent company.Posted on Joshua Morris2024-12-28Trustindex verifies that the original source of the review is Google. I told Stellrr that I would post a review when I had data to back it up. 18 months later, I do: In summer of 2024, we never turned off our A/C. And we saved $1160.71 (58%) vs 2023. This is a likely underestimate of annual savings, since Stellrr installed the foam in May of 2023. I've uploaded a timeline of our gas and electricity bills as we've made multiple improvements--not just spray foam. The gap between what we pay with these improvements and what we would've paid without them will grow bigger forever: energy will never get cheaper. So, here's my empirical take mixed with a bit of common sense: Stellrr's foam insulation provides good value, but without it, other energy-saving improvements will provide half the value they could. It's a foundational improvement--something you do *first*. It's what a nerd's nerd would call "a force multiplier," meaning it makes other improvements vastly more effective by being there. And so you should get it early in your "healthy and efficient home" journey. Unpacking that a bit: from a straight-up balance sheet, we will not ROI on Stellrr, solar, HVAC, electric appliances, and the other improvements we've made. But not breathing all that particulate matter from the nearby interstate? All the gas stove fumes we won't be inhaling? Hell, it's not unlikely we ROI on not having to pay for extended medical care in 30 years. So, if you're into a better quality of life that--bare minimum--mostly pays for itself, I'd recommend doing things In this order: 1. FIRST: Update your ducting, minimally, and your ventilation fans. My only regret--these are hard to do with foam there. 2. Get Stellrr's spray foam. They'll do the best job. 3. Look into a mid-high efficiency heat pump. ($2k tax credit, at least!) Spring a bit extra for an energy-recovery ventilator, installed professionally. Get a UV bulb for that alpine air feeling. 4. Consider solar (30% tax credit til like 2033!)l; also, batteries. 5. If you got those batteries, enroll in Austin Energy's Time of Use program so that you can coast on battery power when electricity is expensive (3-7PM). We do just fine on 20kWh. Bonus: some outage protection! I wasn't the easiest customer--I had a point or two of frustration (communications) with the company during the install. Stellrr sells their product hard, but... like all things ahead of their time, they have to make a complex case that won't appeal to everyone because the value of having an airtight, well-insulated home simply isn't obvious to all. I'm glad I listened--they were right!

FAQS
What type of insulation is best for the hot Texas climate in Round Rock?
For Round Rock’s hot and humid climate, closed-cell spray foam insulation is often the top recommendation. It not only provides a high R-value (a measure of thermal resistance) but also acts as an air and moisture barrier, which is crucial for preventing mold growth and keeping cooled air inside.
How much can I expect to save on my energy bills with new insulation?
While savings vary based on your home’s size, age, and current insulation levels, many Round Rock homeowners see a significant reduction in their energy bills, often up to 40% or more, after a complete insulation upgrade with a product like spray foam.
Is spray foam insulation safe for my family?
Absolutely. Modern spray foam insulation is a safe and eco-friendly product once it has cured. Our certified installers follow strict safety protocols during application, and the cured foam is inert, stable, and does not release harmful chemicals or off-gas.
How long does an insulation installation project take?
Most residential insulation projects in Round Rock, including attic or wall insulation, can be completed in just one to two days. Our team works efficiently to minimize disruption to your daily routine.
Will insulating my attic help with ice dams in the winter?
While Round Rock doesn’t experience severe winters, proper attic insulation and air sealing are crucial for preventing heat from escaping and causing moisture issues. A well-insulated attic helps maintain a stable temperature, protecting your roof structure year-round.
