Expert work ethic and amazing pricing. Very respectable and responsive. Best thing was he was kept in contact with me for months while I finished up some other work and when I was ready he put me in his schedule and knocked it out exactly what I wanted!

I called Nick at Off-Axis about potentially leveling my driveway. He promptly came out, assessed my situation, and identified that my driveway wasn’t sunken, but a buildup of soil erosion on one side, due to improper land grading, was actually my problem. He recommended that a little manual labor could fix my issue with minimal cost to me. He even looked at a few other issues and helped me fix a separate water leaking issue after having new siding replaced. Nick is an honest guy, with an honest opinion. If you’re on the fence about concrete leveling or radon mitigation, I highly recommend Nick at Off-Axis for an honest assessment.

Jimmy Boss★★★★★7 months ago

Off-Axis spray foam was outstanding! Nick was very professional and knowledgeable about his product. Nick is also a very hard worker. My building was clean and he left no mess in the yard. Pricing was very competitive and better than most. If your looking for someone to do spray foam in your house or building I highly recommend Nick at Off- Axis spray foam. 5 stars all day long. Thanks Jimmy

Insulation commandos got the job done and got it done right. We were super impressed with the level of professionalism from beginning to end. Their knowledge went above and beyond my expectations. Chris & his crew did an amazing job AND saved me money. A company with honesty and integrity is so hard to find anymore and we are completely satisfied.

We had our air ducts cleaned and some HVAC duct wrap work done today by Insulation Commandos of Clarksville, and my wife and I couldn’t be more impressed. From the very first interaction—getting a quote from Corrine and being scheduled for the very next day—the whole process was seamless. Corrine clearly knows her stuff and made everything easy and straightforward. The entire crew was polite, professional, and respectful of our home from start to finish. They took great care in every area they worked in, which really meant a lot to us. It’s refreshing (and honestly pretty humbling) to find a company like this, with people who genuinely care about the quality of their work. We’ll definitely be using them again for future projects and would highly recommend them to anyone in need of their services. A big shout-out to the crew who worked at our house—Chase, Kris, Damon, Jackson, and Jaylon (hope I didn’t miss anyone). Excellent job all around!

Sarah Carter★★★★★6 months ago

I did my research before contacting them and I am glad I did! Everything between the customer service and the job they did was a positive experience. They were very communicative and worth every penny. My attic was in horrible condition and now it’s like new. I would recommend them to anyone needing the job done.

My wife and I just settled into our new home. I can honestly say we have never had better repair service than we received today from Joseph from All-Tech garage door service. He repaired and adjusted our garage door for us. He went way beyond just doing an effective repair. He spent time with me explaining how to properly perform maintenance upkeep on the door. His professionalism, courtesy, and time are the best I have ever seen! You better hang on to him… he is an ACE!

Jowilyn Mcbeth★★★★★a month ago

I would like to acknowledge the job well done to our garage. Mr. Joseph is very knowledgeable, he knows what is he doing. He is an assest to the company. He is recommendable , so if you need all jst contact All Tech insulation and spray foam you can depend on.

Doug T.★★★★★3 years ago

I am very pleased with the insulation job that All Tech Insulation did in our pole-barn shop. They added blown-in fiberglass to the attic and closed cell foam on the walls. When they finished up they cleaned up well. I can already feel the difference in temperature when it is above 90°F outside and about 10° cooler inside. I look forward to using my shop in the winter and all-year-around. Andrew kept me updated on the job schedule and helped me understand the overall process. Thank you for a job well done!

Frequently Asked Questions — Spray Foam Insulation in Clarksville

These are the questions Clarksville 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 5 verified Clarksville contractors above for exact quotes.

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