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.

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 Lakeway Insulation Services
How does spray foam insulation perform in Lakeway’s hot Texas climate?
Spray foam insulation excels in Texas heat by creating an airtight seal that prevents conditioned air from escaping and hot air from entering. This superior performance can reduce cooling costs by 30-50% during Lakeway’s intense summer months while maintaining consistent indoor temperatures year-round.
What’s the difference between open cell and closed cell spray foam for Lakeway homes?
Open cell spray foam provides excellent soundproofing and thermal insulation at a lower cost, making it ideal for interior applications. Closed cell spray foam offers higher R-values, moisture resistance, and structural reinforcement, perfect for exterior walls and areas prone to humidity in the Hill Country climate.
How long does spray foam insulation installation take in a typical Lakeway home?
Most residential spray foam installations in Lakeway complete within 1-3 days, depending on your home’s size and project scope. Our team works efficiently to minimize disruption while ensuring thorough coverage and proper curing time for optimal performance.
Is spray foam insulation safe for families living in Lakeway area homes?
Yes, properly installed spray foam insulation is completely safe for residential use. Our certified technicians follow strict safety protocols, and the cured foam is non-toxic and chemically inert. We use only premium materials that meet or exceed all safety standards for occupied spaces.
What energy savings can Lakeway homeowners expect from spray foam insulation?
Lakeway homeowners typically see 20-50% reductions in their energy bills after spray foam installation. The exact savings depend on your home’s current insulation, size, and energy usage patterns, but most customers recover their investment within 2-5 years through lower utility costs.
Does spray foam insulation help with moisture control in Lakeway’s humid climate?
Closed cell spray foam provides excellent moisture control by creating a vapor barrier that prevents humid air infiltration. This is particularly beneficial in Lakeway’s climate, where humidity can cause comfort issues and potential mold problems in poorly insulated homes.
How does spray foam insulation compare to traditional fiberglass in Texas Hill Country homes?
Spray foam significantly outperforms fiberglass by eliminating air leaks, providing higher R-values per inch, and maintaining performance over time. Unlike fiberglass, spray foam won’t settle, compress, or lose effectiveness, making it ideal for Lakeway’s temperature extremes.
What areas of my Lakeway home benefit most from spray foam insulation?
Attics, crawlspaces, and exterior walls provide the greatest energy savings potential in Lakeway homes. These areas experience the most heat transfer, and spray foam’s superior sealing properties deliver maximum impact on comfort and energy efficiency.
Can spray foam insulation be installed in older Lakeway homes?
Absolutely. Spray foam insulation is excellent for retrofitting older Lakeway homes that lack adequate insulation. Our team can access wall cavities, attics, and crawlspaces to significantly improve energy performance without major renovations.
What warranty protection does Stellrr provide for Lakeway insulation projects?
Stellrr backs every insulation installation with comprehensive warranty coverage that protects your investment. Our warranty terms vary by project type and materials used, ensuring you have confidence in your insulation system’s long-term performance and our commitment to customer satisfaction.
