Spray Foam Solutions was a great company to work with, from the initial estimate to the installation and after the job was done. They were courteous, respectful and clean. They did a great job installing the product with a superior quality and I think our workspace was cleaner when they left than it was before they arrived! Their prices are great and their willingness and ability to negotiate on costs and work around our schedule is a breath of refreshing air. Their work was also highly praised by our contractor, electrician, and plasterer. We would highly recommend them for future insulation needs. Like

Byron and his team are top notch! Spoke with them in the morning and they came out same day to give us an estimate. We were having issues with our air keeping up- and everyone recommended making sure our attic was insulated well. Byron was honest saying the insulation we had was good (most places would charge and just do the job). Byron and his team did put insulation over our new office that was uninsulated. HIGHLY recommend them! Very honest, dependable and got the job done quickly. You won’t regret supporting them!

Walt Peele★★★★★9 months ago

I called after I seen his work to inquire about my cargo/camper van, and he said “yes no problem” then explained he generally does buildings and homes, but he has a variety of foam products and can make proper changes and dial in the thickness to make it the right depth for a vehicle without creating too much mess and waste, and also seemed excited with a positive attitude!! …very personable people! I look forward to contracting this project because I think I found just the right guy for the job!

Fantastic job insulating our home. It was a large job removing all of the 14 year old Batt insulation and spray foaming the multiple attic crevasses . It made a dramatic difference in the temperature control of our second floor! Even the A/C technician stated that our unit will run much more efficiently and last longer. The installers were extremely respectful and cared for our newly finished Walnut wood floors. Don’t call anyone else!

Zion and Darius were very professional and great communication throughout our install process. Doug helped us work through the quote and surprised us by getting the work scheduled a week earlier than planned. So far the experience with the team has been very solid

Matthew Gil★★★★★2 years ago

Koala Insulation has a great crew! James came out and quoted the job for spray foam one of only a few that actually sent me the qoute without me having to hound them. Once we decided to move forward the process was super easy James got us on the schedule quickly. Mario did a great job in coming out spraying the room and making it look great. He listened to my request to not shave down the ceiling and I couldn't be happier with the end product! They did a great job cleaning up and left the space in good order when they were done! 10/10 recommend them for all your insulation needs!

My experience with Insulation Magic was excellent. My house is 40 years old and we needed a refresh of our insulation. Chris was fantastic, he was able to promptly come out to give us an estimate. He thoroughly walked us through what we were dealing with and our options. Once we decided we wanted to proceed Chris was able to get us scheduled within the week. The work was excellent, again Chris walked me through everything they touched and showed before and after photos. I highly recommend, pricing was fair, service and communication were excellent.

Best experience I’ve had with a home repair/update. Chris and Insulation Magic are amazing. Came over, identified the project, walked me through every step and gave me a comprehensive quote. Late that night I made a discovery in the attic that was out of scope. But Chris answered me with a game plan seamlessly kept the ball moving. He did an amazing job, going above and beyond any expectations I had. Very professional and a huge upgrade to the longevity of the house. The difference is staggering. Wish I called him sooner. 10/10, will be calling him for all my sealing and insulating needs.

Sonia Sachs★★★★★4 months ago

Chris was absolutely wonderful, from the estimate to the very thorough completion of the job. His attention to detail was more than we have ever experienced with other contractors. The house was left cleaner than as it was when he arrived. He finished a llot of work for our four level house in less time than expected. We are very happy with his work and highly recommend his company.

Insulation Commandos of Charlotte are an incredible company and i would recommend them to everyone looking to get any kind of insulation work done in their home. Simon came out to inspect my attic the day after I called him. He came out on my schedule and inspected the insulation in the attic. After showing me pictures of the original insulation, we sat and discussed what would need to be done. Since i live next to a farm and had a lot of mice issues. Simon explained what his crew would do to take care of everything. He explained that they would vacuum out all of the old insulation (from 1967), then disinfect and clean everything in the attic. They would then seal all of the light soffits, and afterward blow in all new insulation. The entire job took a little more than 1 day, including cleaning everything up. I did get at least 6 other quotes, but no other company came close to the price of Insulation Commandos of Charlotte. Other companies were trying to charge me for each individual item being done. An old cliche, but, forget the rest and get the best... Insulation Commandos of Charlotte!! Thank you so much Simon Linda Daniello

I highly recommend LKN; they went above and beyond to help me decide what I needed for my home, and their work is thorough and high-quality. Randy spent a lot of time on phone calls with me helping me to understand the science and regulations behind spray foam before I ever so much as got an estimate from him, and he stayed late to do extra work on the cracks and crevices of my home beyond what we had agreed on. All of this at a very reasonable price. I thoroughly enjoyed my experience with these gentlemen.

These guys are fantastic to work with and did a very thorough job. As a heavy DIY person I'm always hesitant to "allow" somebody else to do work on my home. For better or worse I probably know too much about what a good job looks like. These guys did an outstanding job and did everything they said they would do and more.

The original technician was not pushy at all and was clearly there to help me and walk me through what I needed and didn't need and provided good dialogue throughout the process. My actual appointment was very easy to schedule, the workers showed up early and got the work done very quick. I had a heat barrier added, my insulation up to code and they also added a cover over my attic access. Highly recommend working with them for any insulation needs!

We are so happy we chose USA Insulation to reinsulate our attic and seal our duct work. We shopped around a bit and found them to be the most comprehensive and affordable. Everyone we spoke with from quote, to scheduling, to service was very professional, responsive, and kind. They found an issue when they came to give an estimate and sent someone out first thing to resolve it before our actual service date. It definitely saved us a lot of $ on heating and air. Nicole was super helpful with scheduling. Conner and team did a great job and made sure everything was sparkling clean before they left. They were very kind to our dogs, too! Our house is noticeably much cooler after they sealed everything up and added insulation. Highly recommend!

Handled insulation on a new construction home for us. Great price! The crew arrived and completed all of the work in a timely manner and our sales rep was very attentive!

Woodman Family★★★★★3 years ago

We have used ABS for insulation construction jobs in the past and have not been disappointed. We are finishing a walk out basement and recently hired them to do the insulation. Keith came out promptly to estimate and even with the current manpower shortage was able to get us scheduled pretty quickly after a few texts back and forth. The basement was poorly insulated by the original builder and not up to current standards. Rick and Joel arrived on time and did an excellent job. They placed fiberglass cavity insulation and sealed the conditioned space with house wrap and sealants. They even sealed gaps between studs. When they were done, they cleaned up and got rid of any garbage. I do most of my own work and am GCing this project since it’s hard to get contractors right now. Insulation can be itchy and dirty work (I break out easily from the fiberglass). It is well worth the cost to have pros come out and get it done and up to code the right way. What took them a day would have taken me at least three or four. I was able to schedule inspections for the following day and can move on to the next step of our finish. Thanks!

Frequently Asked Questions — Spray Foam Insulation in Charlotte

Is spray foam insulation a good investment in Charlotte?
For homes in mixed-humid climates like Charlotte, NC, 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 NC 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 Charlotte?
In mixed-humid climates like Charlotte, NC, 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 NC'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.
