I had the pleasure of working with Strategic Spray Foam of Boone recently and I couldn't be more impressed with their professionalism and quality of work. From the initial consultation to the completion of the project, the team at Strategic Spray Foam was attentive, knowledgeable, and efficient. Not only did they provide excellent customer service, but the results of their spray foam insulation work exceeded my expectations. My home is now more energy-efficient and comfortable, thanks to their expertise. I highly recommend Strategic Spray Foam of Boone to anyone in need of insulation services. Their dedication to customer satisfaction and commitment to excellence truly sets them apart. Thank you, Strategic Spray Foam, for a job well done!

The service I received from Strategic Spray Foam of Boone was superb! Nothing but good things to say here. They were: 1. very professional, 2. communicated well, 3. very informative, 4. showed up on time, and 5. completed the work in the time frame they said. What impressed me the most though, was that they went above and beyond to help my husband and I finish (prepare for inspection) the parts of our addition that we sprayed ourselves (before contacting Strategic Spray). Happy Customer, would recommend to everyone!

Darryl and the team arrived on time and made short work of the job. They got right to it and completed the project fast and efficiently. Darryl was extremely knowledgable as was the team. From a knowledge, job and cost standpoint they can't be beat. I would highly recommend them for any project you might have. Darryl will treat you right and do you right! By the way the office staff is first rate as well. They actually communicate and answer the phone when you call without voice mail mazes and call back recordings. Great all around ! 5 stars!

Kayle, the office manager, was very friendly and helpful. Shane is the GM and he came out personally to give us a quote after inspecting our attic. He offered Energy Star Level R49 L77 Corning insulation which is the better stuff. Shane found some discounts for us and we were able to get far better insulation than we expected for a lower price than another company quoted us. Shane was fantastic! They air-sealed around 20 floodlights in our house and completed isolation of two areas over our porch and garage with a radiant barrier. Darryl lead the team and was very friendly, professional and knowledgeable. We are very happy that we called Insulation 4 All! They are the best!

Karen Auman★★★★★4 months ago

Rehabbing a 90+ yo house. Did a social media search for insulation extraction and called 3 vendors. Insulation 4 All came out same day of call and gave a free estimate that was competitive and reasonable. Excellent and timely communication and very pleased with the finished product. We’ll be talking to them again when we are ready for insulation. Give them a call.

The crew, Kevin & Alex did a fantastic and clean job! Christina took the time to understand my needs and worked with me throughout the whole process to ensure I was happy with their services. The owner, Aaron even came out to meet us and chat for a while. long story short...I had to have my attic insulation fully removed, then have new insulation blown in after replacing my falling ceilings. They went above and beyond to accommodate my needs in regard to scheduling. The cost was well worth the investment because now my home is up to modern standards. They submitted my info for a Duke Energy rebate and even sold me on the benefits of installing a solar powered attic fan. Overall, I was really impressed with their service from start to finish and DEFINTELY RECCOMMEND THEM!!

Joe Hampel★★★★★a week ago

Had groundhog come out and fill up our attic insulation due to it being low after finding them through a duke energy program. They were easy to talk to and explain all the things to be done, and what would or wouldn't qualify for the program through duke. They came out quickly to give an estimate and the work was done quickly and cleanly within a week of accepting the estimate. Can already notice the difference in efficiency in our home. Overall great experience.

Rob Arnett★★★★★a month ago

I found out about Groundhog Insulation through Duke Energy. Their team did a very thorough job of looking over our situation, and gave us a great quote for air sealing and insulation the attic and our garage. Kevin and his crew did a great job, showed up on time and cleaned up well. I'm very pleased with the job they did!

Great Job ! By participating in Duke Energy program connecting to contractors, we connected with USA insulations. Justin came out for estimate.

Their team was great, prompt, done in few hours, cleaned up and walked us thru what they did, double checked work making sure we were happy& satisfied at every step. David followed up with us to make sure all was good as well. All the crew & office personnel were great, very polite, knowledgeable & helpful. We are enjoying the improvements & would recommend using USA Insulation. Thank you USA Insulation !!.

This company was great to work with and they done everything they said they would do. We call and in a couple days Jason came out look around told us what we need and he even compared a few different opinions. The team of Todd ,Raheem and Greg were easy to work with and very well mannered. These guys don't waste anything they finished my house in 1 and 3/4 days. They put all vinyl back and cleaned up what little mess that was made. We r one happy customer and would recommend this company to do your inslation work.

Linda Annas★★★★★a month ago

We needed to insulate a 75 year old farmhouse in the mountains. USA Insulation worked with us to find the best options, including using injection foam insulation in the outside walls. They were professional, friendly and pleasant to work with. They explained not only what they were doing, but also why they were using that method & materials. They also traveled 2 hours each way to provide their services when other companies told us it was not possible to insulate outside walls that old without removing the inside walls then replacing them. We are extremely satisfied with this company, their crew members, and the finished project.

We’ve worked with Renn Building Products for several years and they continue to be one of our most reliable insulation crews. Their work is consistently solid, they show up when they say they will, and they always get the job done right. Highly recommend their team!

John Pyke8 years ago

Someone once said there are two challenges for every company - sales and everything else. Called the company twice and both times no sales person called me back. The question isn't if I am going to buy, but with who. Clearly, Renn doesn't need my business. Onward.

Called multiple times and set appointment up for Friday at 10am. She no showed. Not only that after calling back multiple times and getting told she’d call me back she never did. Very unprofessional.

Frequently Asked Questions — Spray Foam Insulation in Greensboro

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