10/10 Highly Recommended!!! Nick was phenomenal with great communication. He was very thorough with the whole process, what was needed and not necessary to save us money. If you’re looking for insulation help, Nick is your Guy! Can’t thank him enough especially getting everything done before all the cold weather hit!

2 year update, shop without heater on was 55 degrees with outside temp of 4 degrees with snow and ice on roof. Best investment I've made, pay now or pay later for your heating and air-conditioning bill. Espinoza owner of Off-Axis Spray Foam did an excellent job spray foaming my building. Nick is extremely knowledgeable of spray foam products and will educate you on what your best options are for your Insulation needs. Spray foam is also a fire retardant. Veteran owned company that only uses American made products. Check him out and he does more than just insulation.

We had an excellent experience with Off-Axis Sprayfoam from start to finish. The entire process was smooth and professional—from the initial quote, to scheduling, to the final installation. Communication was clear and timely every step of the way. Working directly with the owner, Nick, was truly a pleasure. He was knowledgeable, responsive, and clearly takes pride in his work. The quality of the spray foam installation was outstanding and exceeded our expectations. The pricing was extremely fair, especially considering the quality of work and level of service provided. To put the results into perspective: the outside temperature is currently 17 degrees, and our house is holding at 42 degrees with no heat running yet. That speaks volumes about the effectiveness of our ICF (Insulated Concrete Form) exterior walls combined with the spray foam installed by Off-Axis. We are extremely impressed with the craftsmanship, professionalism, value, and performance. We highly recommend Off-Axis Sprayfoam to anyone looking for top-quality insulation and a company that truly delivers on what they promise.

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!

I couldn’t be happier with the work this insulation company did. From the initial quote to the final cleanup, everything was handled professionally. The team was knowledgeable, respectful of our home, and completed the job quickly. Our house stays warmer in the winter and cooler in the summer now. Worth every penny!

We were very pleased with the service provided by Complete Insulation. Jeff was detailed in providing the scope of work to be done and his pricing was very fair. Fredy and Mario did an excellent job cleaning up our crawl space and installing new vapor barrier. They definitely exhibit pride in workmanship and we couldn’t be happier with the quality of the new vapor barrier system in place. We would highly recommend them!

Jan Young★★★★★5 months ago

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.

Daquan moss★★★★★5 months ago

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!

Not that bad. Arrived early and due to limited space, had to wait for most of the work trucks to leave. No big deal. Yes there is limited space for maneuvers but even a novice can do this. ** They require your tandems to the back and trailer must be flush with dock.

BILL Russell★★★★★a year ago

Delivered truckload today, super tight area but fantastic people working the area. Super fast unload time . Hurting on space but well efficiently managed and very helpful workers. Way better than the old reviews state!

liban elmi★★★★★a week ago

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 6 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.
