So easy! I had Bryant come out and give me a quote. He was very personable and honest. Got lucky to get installation done quickly and efficiently. Jon and Uzman (spell?) were my installers. Very kind and clean! Victoria has been helping me with all the rebates and paperwork to be done! Very professional and friendly! Have already recommended Koala to two people! Excellent work!

Cody and Alex did a superb job removing our attic floor and misc item plus blowing in the insulation. They were polite, professional, efficient and very careful bringing the wood through the house. Also, Bryant was very courteous and professional inspecting the job and estimate. We highly recommend them!

Jean Karam★★★★★a month ago

I recently had Koala install insulation in my attic. There was a bit of miscommunication at first, and the initial install did not meet my expectations. However, Koala went above and beyond to make things right. They answered my calls on weekends and evenings, were always available and helpful, and took every concern seriously. A huge shout-out to BJ for patiently answering all of my questions and to Jeremy and Cristian for their hard work and professionalism. They were clean, thorough, patient, trustworthy, and kind while working in my home. Koala truly stands behind their work, and I would definitely use them again!

A awesome company. Private and family owned company. Gave an estimate on a Wednesday and was out to do the job on the following Friday. A super reasonable estimate and a great job. Cleaned up afterwards. They blew in insulation in the attic of my house and installed an attic tent around the pull down stairs. When unit runs it runs only half as much as it did and is off twice as much as it was. If you need Back Oaks services I highly recommend them. I’m gonna try and upload a before and after pictures.

Mark is the Man! Black Oak got me in with short notice and sent a beast of an installer! Unique situation with the basement and fire blocking so had to call on them to take care of me and they absolutely did. I’m building holes for a living and have no reason to look elsewhere. Thanks guys!

Awesome Company to work with! They do quality work, very efficient, stay in contact with their clients and follow up after the job is done. They replaced a gutter that wasn’t functioning properly. We had contacted several companies to get estimates, but no one ever showed up to do the job. Moses Riley with Black Oak Insulation and Gutters came to look, gave us an estimate the same day, within one week our new gutters were installed and our problem was solved. They also installed new gutters on a new build, did a fantastic job and completed the task in a few hours. Their price is very reasonable! Highly recommend!

I have a 3300 sq ft home that Apex spray foamed and my electric bill never gets over $100.00. In the summer with the heat index of 107 at 1:00 pm you can go in my walk in attic and the temperature will only be about 5 degrees warmer than the temperature in my house. Also, we were able to down size our a.c. unit which saved even more money. Another plus is it's a lot quieter inside the house with the foam insulation . I also had them spray my garage which is around 700 sq ft and it isn't heated or cooled but in the winter it never gets below 60 degress in there. The installers were professionally and completed the job fast. I would recommend Apex to anyone who would be interested in having spray foam insulation put in their home.

Pam Hurt Wright★★★★★8 years ago

We are building a new home and a friend of ours recommended this insulation. Apex Building was very professional with the insulation as well as the clean up. We also appreciated them showing up on time without any delays. Our friend said we will save on all utilities and we are looking forward to seeing this savings. Thank you again Apex Building, Tommy and Pam Hurt Wright

Columbia Crawl Space did an excellent job for us. This is actually the 3rd project they have done. They always show up on time, are very thorough and professional. I highly recommend them!

Coleman Michaels★★★★★2 months ago

Outstanding!! I can't say enough about this company. Mark, the owner, personally came out to inspect the crawl space and walk me through the process. Mark never tried to sell me anything I did not need just to make more money like the prior company I had come out and bid. Not only was Mark's price great, but he used 121 mil on the floor and 1 1/2" spray foam vs the 6 mil and no spray foam the way other company was going to do it. My crawl space was absolutely disgusting from years of mother nature and rats destroying it. I can say I actually enjoy going under the house now! It's clean as a whistle and it's super warm which should help with pipes freezing in the winter. The whole crew at Columbia Crawl Space were great. They were all friendly, professional, and really seemed to care and get the job done right, NO shortcuts.... In a time where money can be tight it's good to know there are still a few companies out there that give you every pennies worth. Do not be fooled by other competitors, read the fine print and know what you are getting. CC space is the real deal.

Diane Klehn★★★★★2 months ago

I had Mark give me a quote for crawlspace encapsulation after I bought my new to me home. Mark’s bid was competitive among the other bids and didn’t try to oversell products & services that other companies included in their quotes for me. I immediately felt comfortable with his demeanor through our conversations and could sense his genuine concern for doing the job correctly without hijacking’s my finances. He waited patiently for me to get the funds together to pay him and didn’t push me into a timeframe that I couldn’t work with. The quote never changed after 2 months. Other companies said I had to get the work done within 30 days or the quote was going to increase. It was Thanksgiving week when the work was done which was already experiencing cold temperatures. As soon as the work was done we could definitely tell a difference in the warmth of our flooring as well as the sound deadening which was an unexpected positive effect of the encapsulation. The crawlspace is now clean and dry and no longer resembles a dungeon. I would not hesitate to recommend Columbia Crawlspace to anyone needing this type of service.

Before you do it yourself, do yourself a favor and contact Hayes insulation for a quote. I reached out with the dimensions of my garage ceiling to be insulated. I got a straightforward quote back in under an hour and the job was completed the next morning. They were communicative, professional and my garage job was perfect! Would 💯 recommend to anyone looking for pro insulation jobs at a great price!

Our 2nd story was significantly hotter than the 1st so we had Munoz Brothers come out to take a look. Our attic was not properly insulated. Sebastian and his crew did an amazing job and were able to get it all done the same day. We’ve noticed a significant decrease in our energy bill and our upstairs is now nice and cool.

Sara Harper★★★★★2 years ago

We are remodeling a late 1940s farmhouse and wanted to have it spray foam insulated. We called several Nashville area companies to get bids and ended up choosing Munoz Brothers Insulation Solutions. First, because Sebastian came out to look at the house the same day we called for a quote, second, because he gave us a very competitive bid, and third, because he was able to do the work in the timeframe we needed it done. He and his crew were very professional and took precautions to keep everything as neat as is possible, as well as cleaning up after they were finished. We will definitely use Munoz Brothers again!

Frequently Asked Questions — Spray Foam Insulation in Nashville

These are the questions Nashville homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 33% typical energy savings. Compare the 20 verified Nashville contractors above for exact quotes.

Is spray foam insulation a good investment in Nashville?▼
For homes in mixed-humid climates like Nashville, 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 Nashville?▼
In mixed-humid climates like Nashville, 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 in Nashville, TN?▼
In Nashville, TN 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 Nashville costs $2,000–$6,000. Most Nashville 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 Nashville, TN?▼
When searching for a spray foam contractor in Nashville, TN, 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 Nashville 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 Nashville 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.
