Posted on luciaTrustindex 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 IngierTrustindex 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 MerzTrustindex 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. Thank you dumpstersaurs dumpsters. Roland M.Posted on John FarleyTrustindex verifies that the original source of the review is Google.

I had a great experience with Stellrr because the team is awesome. Pickle was so helpful and nice to work with. Frank and Jorge did the insulation work and it went super smoothly. The owner, Wayne, is awesome too - thanks for your extra help, Wayne!Posted on LailaTrustindex 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 MorrisTrustindex 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!
Transforming Energy Efficiency Through Building Science
True home comfort requires more than just adding material; it requires a comprehensive understanding of building science and air infiltration. Many homes in the Killeen area suffer from “stack effect,” where conditioned air escapes through the attic while drawing in dust, allergens, and humidity from crawl spaces or wall cavities. By addressing the root cause of energy loss, air leakage, we create a sealed, conditioned environment that protects your family from outdoor pollutants and stabilizes interior temperatures year-round. Our team evaluates your entire structure to prescribe the most effective thermal barrier solution.

Frequently Asked Questions (Killeen & Central TX)
How does spray foam insulation handle the extreme humidity in Killeen?
Spray foam is excellent for humidity control because it acts as an air barrier. Sealing air leaks prevents moist outdoor air from entering your home and condensing within wall cavities or attics. Closed-cell foam, in particular, acts as a vapor retarder, providing an extra layer of protection against the humid Central Texas climate.
Will spray foam help reduce noise from Fort Cavazos activities?
Yes, insulation significantly improves acoustic dampening. Open-cell spray foam is particularly effective at absorbing sound waves. Many Killeen residents find that spray foam insulation helps muffle the noise of helicopters, artillery training, and general street traffic, creating a quieter interior environment.
Is it necessary to remove my old insulation before adding spray foam?
In most cases, yes. To apply spray foam effectively, it needs to adhere directly to the substrate (wood studs or roof deck). Removing old, dusty, or pest-ridden fiberglass allows us to inspect the structure for damage, seal all air leaks properly, and ensure the foam cures correctly without interference from debris.
How long does spray foam insulation last compared to fiberglass?
Spray foam is a durable, long-term solution that does not settle, sag, or degrade over time like traditional fiberglass or cellulose. Once cured, it remains in place indefinitely. While conventional materials may need topping up or replacement every 15-20 years, spray foam is generally considered a lifetime product for the building.
Does spray foam insulation really lower HVAC usage?
Absolutely. By sealing the “building envelope,” spray foam prevents conditioned air from leaking out and hot air from leaking in. This means your HVAC system doesn’t have to work as hard or run as long to maintain your desired temperature. This reduced runtime extends the life of your equipment and lowers energy consumption.
