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.

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 onTrustindex 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!

Common Questions About Spray Foam Insulation in Universal City, TX
What are the biggest insulation problems for homes in the Universal City area?
Many homes in our area, especially older ones, suffer from insufficient attic insulation. Over time, traditional insulation can settle and become less effective, leading to significant heat gain in the summer and heat loss in the winter. Air leaks around windows, doors, and in walls are also common issues that increase energy costs.
How do I know if I need new insulation?
Signs that your insulation may need to be upgraded include constantly running HVAC systems, uneven temperatures between rooms, and higher-than-usual energy bills. If you notice hot spots on your ceilings or walls during the summer, it’s a strong indicator that your current insulation is not performing adequately.
What are the benefits of spray foam insulation in a hot climate like ours?
Spray foam insulation is an excellent choice for Texas homes because it creates a superior air seal, preventing hot, humid air from infiltrating your home. This reduces the workload on your HVAC system, leading to significant energy savings. Closed-cell spray foam also adds structural rigidity to your home and can act as a moisture barrier.
Are there any local or federal rebates available for upgrading my insulation?
Yes, there are often federal tax credits and local utility rebate programs available for homeowners who make energy-efficient upgrades to their homes, including adding or improving insulation. The specifics of these programs can change, so we recommend checking with your local utility provider and a tax professional for the most current information.
Why is attic insulation so important in Texas?
During the summer, the sun beats down on your roof, causing your attic to reach extremely high temperatures. Without proper insulation, this heat radiates down into your living spaces, making your home uncomfortable and forcing your air conditioner to work overtime. A well-insulated attic is one of the most effective ways to combat this heat gain and lower your cooling costs.
