I would like to thank Benton Green Energy for the excellent job they did for our home. We had them put in Cellulose Blown-in Insulation. Dean Benton was on site and supervised and inspected the work performed by his crew. The job was completed in a couple of hours, and they cleaned up after themselves very well. This insulation has made a very big difference with the temperature in the home this July 2025. The temperature is much more even across all the rooms now. This insulation will pay for itself over the next few months just in the energy savings alone, and also the added comfort for me and my family. Again, thank you Benton Green Energy!

I cannot recommend Benton Green Energy enough. Earlier this year, they sealed all the openings in the attic, installed an attic tent over the stair opening, installed insulation, and installed a smart fan. The change in the air quality and energy efficiency has been drastic and amazing. We could feel a difference immediately. Dean was great to work with, and applied for the rebates through Duke Energy for us so we did not have to do anything in order to receive the rebate. The crew was professional and cleaned up after themselves. The cost was exceedingly reasonable and communication throughout the entire process was very easy. It was just a really great experience, and we really appreciate their work.

Benton Green Energy is a great company to work with if you have environmental health issues. Dean made my house feel more like home for me, my wife and infant son. My wife and I have major environmental allergies. Months after we moved into our newly purchased home, we noticed our allergies getting worse and had difficulty maintaining the house's temperature and air quality. I am also hypersensitive to indoor air pressure. In certain parts of the house I would experience painful pressure in my ears, face, shoulders, arms and hands. During the energy audit Dean advised that in addition to installing an attic fan, sealing leaks and beefing up our insulation in our second floor, we get an energy recovery ventilation system (ERV). Not only does the ERV bring in fresh, filtered, air from outside, it removes the polluted air and and creates a positive air pressure in the house. This significantly reduced me and my wife's allergies and helped alleviate the pain I was experiencing from the unbalanced air pressure in the house. Our house is so much more comfortable now. Dean and company genuinely cares about the welfare of his customers and does fantastic work.

Thrilled with the insulation services during our home remodel! The team at Comfort Shield installed insulation in our attic. Their expertise and attention to detail were evident throughout.

Exceptional service from this insulation company! The team was punctual, professional, and the quality of their work exceeded my expectations.

Grateful for their expertise and friendly approach. Highly recommend

Haley Johnson★★★★★2 years ago

Great experience with our attic insulation. We were having an issue with our upstairs not staying the same temperature as the downstairs because of our old attic insulation. They were nice, on time, explained everything to me clearly, and the new insulation looks great and fixed the temperature issue. Definitely recommend

We get our insulation here and I couldn’t be happier. Dave is awesome. Always friendly and helpful. He knows his business and is quick to discuss and educate. I pay my bills quickly but a couple times over the years they have given me a couple extra weeks when I’ve been tight on cash flow.

Frequently Asked Questions — Spray Foam Insulation in Greenville

Does spray foam insulation work well in hot dry climates like Greenville?
Yes — spray foam is highly effective in hot dry climates like Greenville, SC. While moisture control is less of a concern than in humid climates, the air sealing properties are critical for keeping hot desert air out and cooled air in. In extreme heat climates, an unsealed attic can reach 150°F+, dramatically increasing AC load. Spray foam in the attic can reduce attic temperatures by 30–40°F.
What is the best area of my home to insulate in Greenville?
In hot dry climates like Greenville, SC, the attic is typically the highest-impact area to spray foam insulate. Desert sun heats roofs to extreme temperatures, and an uninsulated attic transfers that heat directly into your living space. After the attic, crawl spaces and rim joists are the next highest-impact areas. A local contractor can perform an energy audit to identify where your home loses the most 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.
