I rarely leave reviews, but I had to for Icon Insulation in Chattanooga. We’re in the East Lake area, and our utility bills were through the roof. They diagnosed a poorly sealed attic and a humid crawl space. Within three days, they removed the old insulation, installed new spray foam insulation in the attic, and encapsulated the crawl space. Our home feels tighter, quieter, and our energy use dropped noticeably in just one month. Very respectful team!

Honest, professional, thorough, responsive, knowledgeable and attentive. Very pleasant staff. Very happy with the entire process of our crawlspace encapsulation. Nice to be able to still find local companies that uphold high quality standards with courtesy and hospitality.

I can't say enough good about Independent Insulation. I also highly recommend them for your Insulation needs. If you want someone to shoot you straight, show up when they say, work hard and do it right, then call Howard at Independent Insulation and don't waste your time elsewhere. His crew came on time, polite, and no nonsense. They did a phenomenal job. Punctual and professional. 5⭐️ and will use their services in the future for other projects.

5 STAR FOR SURE! After waiting so many years to do our foam insulation the day is finally here! Best service, promptness and very professional! Great work! Thank you Niel & Eddy!

Wendy Laudone★★★★★3 years ago

Clean, professional, on time and looks great! Neil was very knowledgeable and professional when giving our estimate. After deciding to use him, he gave us a date on his calendar and kept that agreed date. (We have had other contractors for other services push back dates or never show up.) We had closed cell foam applied to the roof, loft and to the crawl space and everything looks great. You will not be disappointed using them for your house/shop/building.

Donna Rankin★★★★★3 years ago

Hernandez Foam installed insulation in my home. They arrived one evening at 5:30 and worked until the job was complete. I was amazed that they worked so late to complete the job. They did an excellent job and returned to finish the ceiling in a timely manner. They are very professional and efficient. I highly recommend their services.

USA Insulation was very timely and professional in the insulation of spray foam. They left our home with no trash behind. We were very pleased with their service and would recommend them in a minute to anyone who is wanting to insulate their home.

Dennis Givens★★★★★11 months ago

USA Insulation is fantastic! They are the very best insulation services. Brandon was professional and helpful during my home energy evaluation, identifying areas to improve efficiency. The installers, Ricky and JB, were professional, confident, knowledgeable, and thorough. They paid close attention to detail during the installation and left everything spotless. Almost immediately after the installation, I noticed the significant improvement in my home’s environment from the air drafts being eliminated and from my furnace having to run less in keeping it comfortably warm. Therefore, I highly recommend USA Insulation for anyone looking to cut rising energy costs. Give Brandon at USA Insulation of Chattanooga a call—you will be happy that you did!

Jason H★★★★★a year ago

Completely Satisfied! We had a wonderful experience with USA from start to finish. The job was done professionally and made an immediate impact on the comfort level of our home. You truly get what you pay for and USA was top notch through the entire process. It is a good product and a job done right. Kudos to Jessica, Brandon, JB and Ricky and Theresa for great service.

We have a very drafty barn with a metal roof. After much research, spray foam insulation was the way to go. We got a couple quotes and Foametix’s was the most competitive. The crew was great. Thorough and did an excellent job with both prep work and clean up. Not only has the foam helped cool down the barn, but the color has also helped brighten up the space. I will definitely be reaching out to Foametix again for my next insulation project!

April Williams★★★★★2 months ago

Definitely recommend! Actually took the time to come out to look at the job to quote it unlike others. The guys doing the job was professional and respectful of the property. You will need some type of electric panel for them to hook up to, just an FYI. They did a great job and cleaned up everything afterwards

We are in the process of selling our home and needed to addd insulation to our attic as part of the sale agreement. Having very little time to get this done, I priced around a few companies. Not only could Koala Insulation service our home quickly they beat out our best quote! Chris and Grant were very professional. They arrived on time and made sure to protect our home during the job. They were very thorough and provided photos of the completed work. Love that because I’m too chicken to climb up the attic. If anyone is looking to have insulation work done please consider Koala!

Mike Ellis★★★★★2 months ago

Koala removed all of my old, blown attic insulation and replaced it with new. Pricing was good and working with Moe, Donna, and Grant was a pleasure. I highly recommend Koala for any insulation needs.

Andrea Meeks★★★★★3 months ago

Jonah Williams★★★★★3 months ago

Top tier insulators with extensive building science knowledge, techniques, and approaches. They are always my go to solution for insulation and air sealing services. AMAZING value for the money too. They even offer dense pack as a service which is very hard to come by in this market!

Jordan Gianos★★★★★2 years ago

Insulation Unlimited re-insulated our attic, improved airflow through the roofline, sealed up attic doors and installed FSK paper to keep heat out of upstairs rooms. The end result was an upstairs that is significantly more comfortable with lower utility bills. I have worked with thousands of contractors in my day job and a few as a customer. This company is knowledgeable about building science and what solutions will have the most value for customers. Communication and follow are reliable, and many employees have worked there for years. Highly recommend this company.

Ivan did an incredible job. I'm a contractor and have had several vaulted ceiling spray foamed with different insulation subs but Ivan has been the best. Fair price, showed up when he said he would, very professional and well-spoken, and left the site clean. I highly recommend the Long of Foam Ivan. Thanks again.

Larry Bouget★★★★★3 years ago

We're building a new house in Sequatchie Valley. We did research on different insulation and wanted to use spray foam but thought it to be cost prohibitive. We contacted different foam insulation companies and thought we would have to use fiberglass batts until we contacted King of Foam Insulation company in Chattanooga. We let them give us an estimate and realized it was within our budget. They took 2 days to complete the job which is what they said. They were very professional, on time and neat. They cleaned the over spray and any shavings they removed. We're totally satisfied and recommend them to do your project. Thank you King of Foam Insulation company.

Allen Williams★★★★★2 years ago

I was in trouble because 31-w ruined my house. Taking months and not able to pass inspection. King of spray foam came in, fixed all of the mistakes by 31-w and saved the day! They were able to do in one day what 31-w could not in months!

Chris And his crew were outstanding. They went above and beyond through every step of the process. The knowledge he shares surpassed days of me studying in a matter of a 30 minute conversation. The spray crew were very polite and explained how the system worked and secured ratio. I feel very lucky to have called Chris with APC Spray Foam

Seth Robinson★★★★★5 years ago

Frequently Asked Questions — Spray Foam Insulation in Chattanooga

Is spray foam insulation a good investment in Chattanooga?
For homes in mixed-humid climates like Chattanooga, TN, spray foam is typically an excellent investment. The combination of hot summers, cold winters, and significant humidity means your home faces insulation challenges year-round. Spray foam addresses all three — providing thermal insulation in both seasons while controlling moisture infiltration. Most homeowners in TN see payback periods of 4–7 years. As with any tight building envelope, ensure your home has adequate mechanical ventilation to manage interior moisture.
How does humidity affect spray foam insulation performance in Chattanooga?
In mixed-humid climates like Chattanooga, TN, moisture management is as important as thermal performance. Closed-cell spray foam acts as a Class II vapor retarder, preventing moisture from infiltrating walls and attics where it causes mold and structural damage. This dual function — insulation plus moisture control — is why spray foam outperforms traditional insulation options in TN's climate. However, because the building envelope becomes tightly sealed, proper mechanical ventilation is strongly recommended to allow interior moisture from daily activities to escape without losing 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?
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. 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 costs $2,000–$6,000. Most 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?
Look for contractors 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 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 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.
