Jesse Drerup and his team are the best contractors I've ever worked with! Jesse is so talented at his crafts, is full of integrity, and a joy to work with. He is extremely knowledgeable in so many areas and has a very strong team of helpers. On top of being skilled craftsmen, they are also kind, honest, and funny--bonus! In our last project, Jesse's team came in ahead of schedule and under budget! I can't recommend them highly enough.

Their team was not only professional and punctual but also incredibly knowledgeable about the best options for my home. They took the time to explain the entire process and the materials they planned to use, and they patiently addressed all my questions.

Travis and his team did an exceptional job with our HVAC and insulation. The crew was fast, efficient, and left everything clean. Travis offered a very competitive price compared to other quotes and went above and beyond by helping me troubleshoot airflow dead spots in my home. He and his team updated the ducts and vents, significantly improving air circulation. Since the new insulation was installed, the temperature throughout the house is noticeably more consistent, and my heater and AC no longer have to run all day. Highly recommend!

Margaret Flood★★★★★a month ago

We hired Cooler Green Solutions to help us update the insulation in our 1979 home. We had open cell foam insulation installed. What a great experience working with Travis and his crew. They cleaned out our old attic insulation and installed the new insulation. We've already noticed that our air conditioner isn't working as hard to cool the house and the humidity dropped as well. Travis listened to what we were experiencing with our cooling system and gave us a proposal that had the options we needed without add ons that we didn't need. Our attic temperature dropped about 40 degrees after the insulation installation. An excellent experience overall.

I recently had my two-story home in Dripping Springs serviced by Cooler Green Solutions, and I couldn't be more impressed. My house presented a real challenge with its hard-to-reach attic spaces, but Travis and his team tackled the project with unmatched expertise and professionalism. From the start, it was clear that Travis and his crew were highly knowledgeable. They thoroughly assessed the situation, which included removing insulation that had been contaminated by rodents. The removal process was meticulous, ensuring that every trace of the old insulation was gone and the space was properly cleaned and prepped for the next step. The spray foam insulation they applied is top-notch and has already made a noticeable difference in the comfort and energy efficiency of my home. Despite the tricky access points and the complexity of the job, they executed everything flawlessly. They worked diligently, communicated clearly throughout the process, and left the work area spotless when they were done. If you're looking for a spray foam company in Austin, Cooler Green Solutions is by far one of the best. Their combination of professionalism, skill, and attention to detail sets them apart. I highly recommend Travis and his team to anyone needing insulation services, especially if your home requires specialized expertise like mine. Five stars all the way!

Shawn Brennan★★★★★a month ago

Heatbusters was amazing! Every step of the way they were true professionals from top to bottom. Every person I dealt with from Jim the owner on down was excellent. They gave me a very fair price and did excellent work. They removed old insulation, cleaned, sealed leaks, sanitized and put 17inches of new insulation in a 4k sft house. They were on time, cleaned up everyday, and worked very hard. These guys really did an excellent job for me- highly recommended!

Luis Zamorano★★★★★2 months ago

Great insulation work done from the crew. Professional and quick. Jim, our sales manager, was great to explain the process, discuss our needs and ensure that we were getting the right kind of work done. Other insulation companies we talked to just looked around for 30 seconds to take measurements and quoted us immediately without even asking anything, what we were doing or our goals for the project. Recommend the heat busters!

They did such a great job repairing the can lights in our ceiling. So many other contractors turned us down since they were worried about the paint not matching up. I don’t even need to paint over it because it looks that GOOD! I am so happy with the job they did. Plus got much higher quotes from other company’s. Their prices were fair. Highly recommend!!

Hannah McBride★★★★★3 months ago

The Attic Wrangler removed raccoons from our attic. Zach removed two layers of soiled and compacted old insulation, cleaned and sealed the attic, and added new insulation. He also advised us on finding repairs for the damaged ductwork. He took pictures at every stage. He is professional, thorough, and explains everything clearly. I highly recommend him!

powerplaytoo360★★★★★a year ago

I had an amazing experience restoring my attic with Zach's company Attic Wrangler. Zach scheduled the estimate walk through right away. Zach provided an incredibly reasonable quote. Zach and his team ensured that all areas were covered before working. He explained each step of the process to me and checked in regularly while work was being performed. It was an amazing experience working with such a humble, polite, hardworking and trustworthy individual.

Tara Visker★★★★★3 years ago

I cannot recommend the Attic Wrangler enough! Zachary went above and beyond. I called him late in the afternoon on a Tuesday, and he was over that same evening, with a full quote just a few hours after he left. He made me feel like our situation was a priority. He was extremely communicative and fairly priced. So professional and just a nice guy. Don't waste your time on a chain, go with the Attic Wrangler - he knows what he's doing!!

Stellrr did a great job of fixing my original foam contractors poor work for a very reasonable price. They also added sound insulation to my theater ceiling and cleaned up after themselves and the original contractor. I’m a very satisfied customer.

James Walker★★★★★a month ago

The Stellrr team did a great job! The price was very competitive with more options than others, and Pickle and the team really helped me out working around other contractors. The guys showed up and got to work done super fast and communicated status before, during, and after the job was done. Very happy with Stellrr and the work they did.

Frequently Asked Questions — Spray Foam Insulation in Austin

These are the questions Austin homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 30% typical energy savings. Compare the 7 verified Austin contractors above for exact quotes.

Is spray foam insulation a good choice in hot and humid climates like Austin?
Absolutely. Hot and humid climates like Austin, TX are actually where spray foam insulation delivers some of its best results. Closed-cell spray foam acts as both an insulation layer and a moisture/vapor barrier, preventing the humidity infiltration that causes mold, rot, and air conditioning inefficiency. Homeowners in TX typically see 20–35% reductions in cooling costs after installation. One important note: because spray foam creates a tight building envelope, proper mechanical ventilation is essential in humid climates to manage interior moisture from daily activities like cooking and bathing.
What type of spray foam is best for homes in Austin?
In hot and humid climates like Austin, TX, closed-cell spray foam is generally recommended for exterior walls, crawl spaces, and attics. Its high density creates a moisture barrier critical in humid environments. Open-cell foam can be used in interior walls for soundproofing and actually allows some vapor movement, which can be beneficial in certain wall assemblies. A qualified local contractor can assess your specific home and recommend the best approach.
Can spray foam insulation help reduce my AC bills in Austin?
Yes — significantly. Air conditioning accounts for the majority of energy costs in hot climates like Austin, TX. Spray foam seals all gaps and cracks that allow conditioned air to escape, which is the primary cause of high AC bills. Most homeowners in hot climates report 20–30% reductions in cooling costs after spray foam installation.
Is spray foam insulation worth the cost?
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Austin, TX?
In Austin, TX and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Austin costs $2,000–$6,000. Most Austin homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Austin, TX?
When searching for a spray foam contractor in Austin, TX, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Austin contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Austin for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
