Before settling on Green Earth Spray Foam to insulate our new home I met with and discussed my project with four of their competitors. Our project included open cell spray foam in the attic and all above grade exterior walls, closed cell spray foam on on below grade exterior walls and rock wool sound proofing between floors and living areas. Green Earth's pricing was very competitive and I felt very confident they were experts in installation. Matt Youmans at Green Earth was a joy to work with. Professional in every way. He enthusiastically approached our project to make sure the insulation solutions were a perfect match for our project and budget. His team delivered everything they promised on a timely basis. And he expressed true gratitude for having the opportunity to insulate our new home. My builder has 40 years of building experience and he was also very impressed by the quality of their work. I'm beyond impressed and thrilled to have chosen Green Earth Spray Foam and recommend them without reservation. If you need insulation for your home or business, reach out to Matt. You'll be glad you did.

I am absolutely ecstatic with the Green Earth Spray Foam Company. From the initial meeting and the quick turn around of their proposal. To the ease of the scheduling date. They showed up right on time and immediately went to work. The work was excellent which includes their prep’ and the clean up. The crew was friendly and courteous. With temperatures already heating up outside the benefits of the Green Earth Spray Foam Insulation can already be felt with cool/comfortable temperatures inside. I highly recommend!!!!

My experience with Green Earth Spray Foam was great, from the initial consultation to completion of the job. Matt initially inspected the attic area & offered recommendations that would help with differences in seasonal temperatures upstairs as well as overall energy efficiency. I received their proposal quickly & it was competitively priced. The team that came to do the work was efficient & professional. They completed the job in several hours & cleaned up before they left. I’m glad I chose Green Earth to do the work.

Great experience with Spray Foam Solutions! They removed some loose foam on my attic floors and foamed a couple small spaces. From estimate to scheduling and work they were very easy to work with. Ekram & Amir were awesome. Great communication. Thorough work. Great cleanup of site in and around home. Would highly recommend!

Reliable and affordable company. Easy process. We called them, Judith came to check and quoted the job. She scheduled the installation, and in a week I was enjoying better temperatures and cleaner air at home. The installation was an easy process. Amir and his coworker did an amazing job. I like how my attic looks now.

Frequently Asked Questions — Spray Foam Insulation in Lawrenceville

These are the questions Lawrenceville homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 27% typical energy savings. Compare the 3 verified Lawrenceville contractors above for exact quotes.

Does spray foam insulation work well in hot dry climates like Lawrenceville?
Yes — spray foam is highly effective in hot dry climates like Lawrenceville, GA. 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 Lawrenceville?
In hot dry climates like Lawrenceville, GA, 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 in Lawrenceville, GA?
In Lawrenceville, GA 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 Lawrenceville costs $2,000–$6,000. Most Lawrenceville 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 Lawrenceville, GA?
When searching for a spray foam contractor in Lawrenceville, GA, 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 Lawrenceville 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 Lawrenceville 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.
