Roland Merz2025-08-06Trustindex 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. John Farley2025-07-24Trustindex 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.

Highly recommend them to anyone looking for quality insulation work! Camella Bridges2025-04-27Trustindex 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! Laila2025-04-08Trustindex 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. Joshua Morris2024-12-28Trustindex 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! Taylor Morales2024-01-05Trustindex 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 Albian Barban2024-01-05Trustindex 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.

Common Insulation Questions for Bertram Homeowners
What’s the best insulation type for Bertram’s climate conditions?
Closed-cell spray foam insulation performs exceptionally well in Central Texas due to its superior moisture resistance and thermal barrier properties. It effectively handles our hot, humid summers while providing excellent protection during occasional winter freezes, making it ideal for Bertram’s variable climate patterns.
How much can proper insulation reduce my energy bills in Bertram?
Most Bertram homeowners see 25-45% reductions in their monthly energy costs after professional spray foam insulation installation. The exact savings depend on your home’s size, age, and current insulation condition, but the investment typically pays for itself within 3-5 years through utility bill reductions.
Is spray foam insulation suitable for older homes in historic Bertram?
Absolutely! Spray foam is perfect for retrofitting older Bertram homes because it expands to fill irregular spaces and gaps common in vintage construction. We’ve successfully upgraded many historic properties while preserving their architectural integrity and character.
How long does insulation installation take for a typical Bertram home?
Most residential insulation projects in Bertram are completed within 1-2 days, depending on the home’s size and scope of work. We work efficiently to minimize disruption to your daily routine while ensuring thorough, professional installation throughout your property.
Do I need permits for insulation work in Bertram, Texas?
Generally, insulation installation doesn’t require permits in Bertram for most residential applications. However, we handle all necessary paperwork and ensure compliance with local building codes and regulations, giving you peace of mind throughout the entire process.
