Chris Cato★★★★★a week ago

Very impressed with this company. I received quotes from several companies and Koala’s price was far better than the rest. Throughout the bid, job execution, and follow-up Charlie was very quick to respond to any question I had. The install crew was equally great. Very knowledgeable and experienced in applying the foam and solving my specific insulation application challenges. Do yourself a favor and call this company to bid your job. Thanks fellas!

Koala Insulation of Dallas was a fantastic choice for my project. Charlie is incredibly knowledgeable and a pleasure to work with. Partnering seamlessly with my contractor, Charlie brought expertise and insights that made a huge difference. His professionalism and attention to detail ensured everything went smoothly and on schedule. Not only is he trustworthy, but he also guarantees his work will pass energy inspections, giving us total peace of mind. I highly recommend Koala Insulation of Dallas and especially Charlie for anyone looking for quality work and dependable service!

We needed to add insulation to our new house (a 25 year old attic with barely any insulation) and sat through several vendor presentations on spray foam, radiant barrier, etc. Once we met with Koala, I knew their no nonsense approach was right for us. No big sales pitch, just honest recommendations that would help our situation. I didn’t feel pressured or oversold and the pricing was reasonable. They had it done a few days later. I highly recommend their services!

I had a great experience from start to finish. Estimator/Service Advisor Jeffrey Stuart accommodated my schedule by coming out when it was convenient for me. I had an afternoon open, so rather than pushing it out a week so it wouldn't be so hot while he was measuring(I wouldn't have blamed him, summer's really been hanging around this year), he came right over. I was impressed with his manner, professionalism, and expertise, so much so that I pulled the trigger and accepted the proposal shortly after he left. Next up was scheduler/coordinator Gie. She was pleasant, courteous, and responsive, and made me feel that she was going to be super accountable and diligent. She did what she said when she said without the typical misses or postponements/excuses so common these days. Project manager Tyler clearly laid the process out, and stopped by before and after. He made sure I was pleased and had no unanswered questions or concerns. I was lucky enough to get the install done by the team of Aldo and Armando. Prompt, competent, tidy and as quiet as circumstances/machinery allowed. They were just great and I was super comfortable to have them working at my home. Price was very reasonable too. AC is running less and garage is outside temp+ 3 or 4 degrees; it had been +20-25. Top notch job and I couldn't be more pleased!

Our experience with Superior Attic was fabulous. We had Jonathan out to check out the attic and provide us with different options for keeping the home very cool. We decided to go with the spray foam insulation between the rafters. We have just completed a full week with new insulation and so far have noticed a difference, cant wait to see our bill lower. We also had duct cleaning done which was needed. Seamless process!! Had another project done, came out great!! Love the process.

Superior Attic did a wonderful job from start to finish on our insulation replacement. I was impressed with the level of professionalism displayed by the entire team, including Steven, Tyler, Aldo, Jamie and office staff. Great communication and on time. The day of the job, the team worked hard all day, no loud music, no shouting or lounging around - just worked hard and finished the job ahead of schedule. They insulated areas that our builder had not, so this was well worth it! So happy with the work they did!

Frequently Asked Questions — Spray Foam Insulation in Southlake

These are the questions Southlake 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 2 verified Southlake contractors above for exact quotes.

Does spray foam insulation work well in hot dry climates like Southlake?
Yes — spray foam is highly effective in hot dry climates like Southlake, 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 Southlake?
In hot dry climates like Southlake, 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 Southlake, TX?
In Southlake, 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 Southlake costs $2,000–$6,000. Most Southlake 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 Southlake, TX?
When searching for a spray foam contractor in Southlake, 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 Southlake 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 Southlake 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.
