We needed to have a job done quickly and they were very accommodating and even were able to move our appointment up a day.

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 Killeen Insulation Services
How does spray foam insulation perform in Killeen’s hot Texas climate?
Spray foam insulation excels in Texas heat by creating an airtight seal that prevents hot air infiltration and keeps conditioned air inside. This thermal barrier significantly reduces cooling costs during Killeen’s intense summer months while maintaining consistent indoor temperatures.
What’s the difference between open cell and closed cell foam for Killeen homes?
Open cell foam offers excellent thermal performance and sound dampening at a lower cost, making it ideal for interior applications. Closed cell foam provides superior moisture resistance and structural strength, perfect for exterior walls and areas prone to humidity in Killeen’s variable climate.
How long does spray foam insulation installation take in a typical Killeen home?
Most residential spray foam projects in Killeen take 1-3 days depending on square footage and complexity. Our efficient installation process minimizes disruption to your daily routine while ensuring thorough coverage and proper curing.
Can spray foam insulation help reduce allergens in Killeen homes?
Yes, spray foam creates an airtight barrier that prevents outdoor allergens, dust, and pollutants from entering your home. This improved indoor air quality is especially beneficial for Killeen residents dealing with seasonal allergies and airborne irritants.
Is spray foam insulation safe for families and pets in Killeen?
Professional spray foam insulation is completely safe once properly cured. Our certified installers follow strict safety protocols during application, and the finished product is non-toxic, providing decades of safe thermal protection for your family.
How much energy can Killeen homeowners save with spray foam insulation?
Killeen homeowners typically see 30-50% reduction in heating and cooling costs after spray foam installation. The exact savings depend on your home’s current insulation, square footage, and energy usage patterns.
Does spray foam insulation work in older Killeen homes?
Spray foam is excellent for older homes because it seals air leaks and gaps that traditional insulation cannot address. Many historic Killeen properties benefit significantly from spray foam retrofits that preserve character while improving energy efficiency.
What areas of my Killeen home benefit most from spray foam insulation?
Attics, crawl spaces, and exterior walls typically provide the greatest energy savings when insulated with spray foam. Our Killeen team can assess your specific property to identify priority areas for maximum efficiency gains.
How does Killeen’s humidity affect spray foam insulation performance?
Spray foam actually helps control humidity by creating moisture barriers and preventing condensation issues. This is particularly valuable in Killeen where humidity levels can fluctuate significantly throughout the year.
What warranty does Stellrr provide for spray foam insulation in Killeen?
We stand behind our work with comprehensive warranties covering both materials and installation. Our Killeen customers receive detailed warranty information that ensures long-term protection and peace of mind for their insulation investment.
