Trustindex verifies that the original source of the review is Google. Stellr Insulation was fast and efficient. We needed to have a job done quickly and they were very accommodating and even were able to move our appointment up a day. We especially appreciated Pickle as he always kept us informed throughout the process! Ashley Kolar2025-07-02Trustindex verifies that the original source of the review is Google. Very efficient, really friendly service, highly recommend all around Michael Cleveland Osborne2025-06-20Trustindex verifies that the original source of the review is Google. Choosing this company for our attic insulation was a great decision. They got the job done quickly and efficiently, and their team was super organized and professional. Everyone was courteous, and they left the space spotless when they finished. We're really happy with the results, our home feels more comfortable and energy-efficient already. Highly recommend them to anyone looking for quality insulation work! Nathaniel Granger2025-06-12Trustindex 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! Camella Bridges2025-04-27Trustindex 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. Laila2025-04-08Trustindex 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! Joshua Morris2024-12-28Trustindex verifies that the original source of the review is Google. i called to get a quote to top off my attic insulation they call this putting lipstick on a pig! lol had them come out for a diagnostic and they uncovered the real deal about what was going on. i hired them and it took several weeks to get on the schedule to do the work they did a really good job. very happy Taylor Morales2024-01-05Trustindex verifies that the original source of the review is Google. I like working with the Stellrr team on my crawlspace conversión. It was dirty and moldy. Now it is súper clean and I can store my stuff down there. A plus. Albian Barban2024-01-05Trustindex verifies that the original source of the review is Google. I would recommend Stellrr to anyone. They insulated my attic at a fair price and I know I can trust them. Angel and his team replaced the old fiberglass insulation in my attic with cellulose, air-sealed my attic, and insulated my catwalk. They were on-time, communicative, and did great work. I was impressed every step of the way. They also went above and beyond, adding extra insulation at no charge! Mr. Wayne followed up weeks later for quality control and added more insulation and air sealing that was even more than what we had contracted for. I can't recommend Stellrr enough! This isn't a paid promotion or anything, I just think more people should contract with Stellrr and want to let people know that my experience with them was phenomenal. I recommend them 100%. Christian Rice2024-01-05Trustindex verifies that the original source of the review is Google. From my first phone call with Jeremy, to my consult with Sheldon… and the install crew, I could not be more pleased with how respectful everyone was. They vacuumed out all the old insulation. We don’t know the house had rat problems because it had been burried. But I’m so glad to have that out of the house. And now our air is so much cleaner. They spray foamed the roof for me and it is just like a cozy blanket. Amber Spring2024-01-05

Common Questions About Spray Foam Insulation in Harker Heights
How does spray foam insulation perform in Central Texas climate conditions?
Spray foam insulation excels in Central Texas’s hot summers and mild winters by creating an effective thermal barrier and air seal. It prevents conditioned air from escaping and blocks outdoor heat from entering, maintaining consistent indoor temperatures while reducing HVAC workload throughout the year.
What makes spray foam superior to traditional insulation in Harker Heights homes?
Unlike traditional insulation materials, spray foam expands to fill gaps, cracks, and irregular spaces completely. This creates an airtight seal that prevents air leakage, moisture infiltration, and thermal bridging – common issues with fiberglass or cellulose insulation in Texas homes.
How long does spray foam insulation installation take in residential properties?
Most residential spray foam insulation projects in Harker Heights are completed within one to three days, depending on the property size and areas being insulated. Attic installations typically take 4-8 hours, while whole-house applications may require 2-3 days for proper curing and completion.
Will spray foam insulation help reduce my energy bills in Harker Heights?
Yes, properly installed spray foam insulation typically reduces energy consumption by 30-50% by eliminating air leaks and improving thermal efficiency. Many Harker Heights homeowners see immediate reductions in their monthly utility bills, especially during peak summer cooling seasons.
Is spray foam insulation safe for families and pets in residential applications?
Professional-grade spray foam insulation is completely safe once properly cured. Our certified installers follow strict safety protocols during installation, and the final product is non-toxic, odorless, and safe for occupants of all ages, including children and pets.
What’s the difference between open cell and closed cell spray foam for Texas homes?
Open cell spray foam is lighter, more cost-effective, and excellent for interior applications and sound dampening. Closed cell spray foam is denser, provides structural strength, offers superior moisture resistance, and is ideal for exterior walls and areas prone to humidity in the Texas climate.
How does spray foam insulation handle moisture and humidity in Central Texas?
Closed cell spray foam acts as both insulation and vapor barrier, preventing moisture infiltration and condensation issues common in humid Texas climates. This helps prevent mold growth, wood rot, and structural damage while maintaining indoor air quality.
Can spray foam insulation be installed in existing Harker Heights homes?
Absolutely. Our experienced technicians specialize in retrofit installations for existing homes, including attics, crawlspaces, and wall cavities. We use specialized equipment and techniques to ensure complete coverage without disrupting your daily routine.
What maintenance is required for spray foam insulation after installation?
Spray foam insulation requires minimal maintenance once installed. It doesn’t settle, sag, or degrade like traditional materials. Periodic visual inspections are recommended, but the insulation typically maintains its performance for decades without requiring replacement or maintenance.
How do I know if my Harker Heights property needs new insulation?
Common signs include fluctuating indoor temperatures, high energy bills, drafts, ice dams, moisture issues, or insulation older than 15-20 years. Our professional assessment can evaluate your current insulation performance and recommend appropriate upgrades for optimal efficiency.
