Koala Insulation exceeded expectation! It feels cool even with the a/c off. Punctual and kept contact at every point. Our inspector and sales rep, Austin was very professional and got us set up very quickly. Sergio and Antonio did our removal. Ezra and Anthony handled our reinsulation. They all were punctual, efficient, professional and very pleasant despite our super tiny and nasty attic! Would recommend!

Bottom line: I would hire them again. They're all very professional and made sure to account for my concerns. I found Koala via Angie's list. I made a request for a quote and in no time at all, I was in contact with a member of the team. I was scheduled easily and a representative (Andrew) from Koala came to look at my attic. Andrew investigated and showed me where the problem areas were. He prepared options and recommended actions while he was in person. Then he prepared a quote and e-mailed it to me. I accepted it and then he scheduled a crew to come out... All in the same visit. When his crew came out and they were so kind. They asked me to look at the attic space after they did their work and see what I thought. They were very interested in my input and addressed all my concerns. I'm very glad I hired them. Great work Koala!

5 Star Service! First interaction was getting scheduled for a quote, where Tom showed up on time and took direct measurements of my attic for insulation removal. I was very happy that he took measurements manually and with a laser tool rather than the typical run-of-the-mill contractors measuring from the outside perimeter of house. Tom took this back and sent me a formalized quote later and I was very satisfied with his pricing. We scheduled the service for a month out since he had ordered a brand new vacuum machine and it would not arrive until then. There was a delay in the commercial vac order, but Tom was very professional and notified me immediately so we could reschedule. The day of the insulation removal came; Tom and his team showed up on time and started working immediately. I have a large 2 story home so they ran the hoses through the 2nd story window. They were very knowledgeable and considerate of my floors and possible damage by covering surfaces and tying off hoses to prevent unwanted movement. It took them about 6 hours nonstop to vacuum the entire attic out. After completing they sprayed the attic with a disinfectant and installed a smoke alarm. They did not have on the truck that day but they came back a couple days later and installed the attic door tent. Overall, I was extremely pleased with Tom and his team’s professionalism; I would recommend Geo-Insulation for anyone looking for insulation services!

The service we received was exceptional. Tom guided us through every part of the insulation process and answered every question we had. He had a positive attitude even though he had to go into a sweltering attic. He was on time, on point, and the entire process was very quiet. I was able to work in the next room without hearing much of anything. He cleaned up afterwards and helped us get a rebate from CPS. Highly recommend this company.

Honest people work here! My inspector said the spray foam in my attic was lacking an intumescent (fire protection) coating which costs about $2,000. I called this company to review the specifics of my attic, and they said the coating was not needed, even though they could have said yes and charged me to do it. Much appreciated!

Small location , busy businesss , receiving starts @8am. But can check in before, wait in the street parked across the business till they call you . There was a truck in front and they got us in at the same time. No problems docking plenty of room to turn.

Player 1★★★★★2 years ago

My company put a lock behind my pre-loaded trailer and forgot to take it off. The workers at this place got a grinder and cut it off. They were real cool about it and i am grateful for that. Great service. They unloaded a full trailer in 30 minutes. If you get here early, you can park in the street next to the sidewalk. Make sure you don't block the business right across from their gate. The gate is on the far right. The docking might seem daunting, but don't worry about it. They make you enter through the gate and go behind the building where you can pull forward and do a 45° docking. It's not bad at all. Just be careful not to hit the vehicles that are moving around and you should be fine. Workers will guide you. Friendly service, fast unloading. I wouldn't mind coming back here again.

Frequently Asked Questions — Spray Foam Insulation in New Braunfels

These are the questions New Braunfels homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 27% typical energy savings. Compare the 5 verified New Braunfels contractors above for exact quotes.

Does spray foam insulation work well in hot dry climates like New Braunfels?▼
Yes — spray foam is highly effective in hot dry climates like New Braunfels, TX. While moisture control is less of a concern than in humid climates, the air sealing properties are critical for keeping hot desert air out and cooled air in. In extreme heat climates, an unsealed attic can reach 150°F+, dramatically increasing AC load. Spray foam in the attic can reduce attic temperatures by 30–40°F.
What is the best area of my home to insulate in New Braunfels?▼
In hot dry climates like New Braunfels, TX, the attic is typically the highest-impact area to spray foam insulate. Desert sun heats roofs to extreme temperatures, and an uninsulated attic transfers that heat directly into your living space. After the attic, crawl spaces and rim joists are the next highest-impact areas. A local contractor can perform an energy audit to identify where your home loses the most conditioned air.
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 New Braunfels, TX?▼
In New Braunfels, 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 New Braunfels costs $2,000–$6,000. Most New Braunfels 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 New Braunfels, TX?▼
When searching for a spray foam contractor in New Braunfels, 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 New Braunfels 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 New Braunfels 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.
