One of the options provided by my Duke Energy Home Energy Report. Standard Insulating Company were very easy to work with, honest about the services I needed and also provided them at a great cost. 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!

I had a fantastic experience with Standard Insulation Company. They installed insulation in my attic and provided an attic door cover, and the entire process was smooth from start to finish. The team was precise, kind, and incredibly thorough. They followed up with me at every stage, making sure my needs were understood and fully met. I truly appreciate their professionalism and attention to detail. Highly recommend

We had new insulation installed in our crawlspace. They were able to schedule us quickly , got the job done quickly and did a fine job. Everyone we dealt with was extremely nice and they did exactly what we wanted without trying to add on and upsell. Their price was reasonable and lower than many. I highly recommend this company

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.

Ryan Krause★★★★★9 months ago

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.

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

5 stars for Simon and the rest of the Insulation Commando’s crew. They recently encapsulated my crawlspace and did a fantastic job. They were punctual and professional and easy to communicate with throughout the project. The finished product was done meticulously and they didn’t cut any corners. Their price was reasonable and I wouldn’t hesitate to use them again at a future home. I highly recommend

Simon and the team at Insulation Commandos of Charlotte were amazing from start to finish. Professional, punctual, and incredibly knowledgeable—they explained everything clearly and made the whole process easy and stress-free. The crew worked efficiently, respected the space, and the quality of their work really shows. Huge improvement already! If you’re looking for top-notch insulation work and a team you can trust, Simon and his crew are the ones to call. Highly recommend!

Linda Daniello★★★★★2 weeks ago

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 hired Home shield to encapsulate my crawlspace. Their personnel were very professional, hardworking and completed the job in two days for a very reasonable price. I got six quotes with Home Shield being the last one. I'm glad I did not cancel the appointment. I recommend this company they did a great job.

Pamela Wyman★★★★★2 weeks ago

Working with Carter and Silas was a great experience. They were very personable, professional, thorough, – talk about enthusiasm! You have never met two people that are more excited about stealing your attic and getting things insulated correctly! Appreciate the great work they did, the cleanup and the process.

John F★★★★★a week ago

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 tag team of Silas and Carter made the difference for me. Very courteous and professional. Can't say enough good things about them!!

I had a great experience doing business with USA Insulation. I got the reference from the Duke Energy website, and from the initial visit for the estimation through the service execution, the crew was truly professional and polite. They executed the service quickly and with great quality for a fair price. I strongly recommend doing business with them!

Derek S.★★★★★a week ago

The process from receiving a quote to the work being performed with USA Insulation went very well. Prompt to respond and fair pricing. Partner with Duke Energy. Crew was nice and did a good job too.

Shar Campbell★★★★★3 months ago

My first contact was with Nicole and Parker. Nicole was easy to reach and she stayed on top of each part of the process from start to finish. Parker was quite knowledgeable. He mentioned things about the attic insulation that three other companies had not mentioned. He also was the first to explain the Duke Energy and Federal Tax rebates. The crew was respectful, friendly, efficient, and cleaned up after themselves. I am quite satisfied!

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!

A truly great experience. My home is so warm In the winter and I know it’s because of the insulation Austin Co. put in my home. Not to Mention the gutters are top notch. No rain escapes from them. Do your home a favor, call Austin if you need insulation or gutters.

Frequently Asked Questions — Spray Foam Insulation in Charlotte

These are the questions Charlotte 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 13 verified Charlotte contractors above for exact quotes.

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 in Charlotte, NC?
In Charlotte, NC 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 Charlotte costs $2,000–$6,000. Most Charlotte 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 Charlotte, NC?
When searching for a spray foam contractor in Charlotte, NC, 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 Charlotte 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 Charlotte 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.
