Foam South brings to your job experience, expertise, and an unsurpassed reputation. John Dodd arrived and gave us a quote that was detailed and reasonable. They worked with us on our timeframe as our days were moving targets. Christian and Jesus arrived wrapped everything that was not to be foamed. They were respectful of our home, kind and friendly. Additionally, they were kind and made friends with my pup. Sophie approved. While they mentioned that there may be some odor to the product, we experienced no odor after application. After two weeks, the product has zero smell whatsoever. We’ve already seen an improvement in the air quality in our room, and our energy costs are trending down. Bravo to the entire Foam South team, John, Christian and Jesus. There are a lot of spray foam contractors in the Atlanta area. Do yourself a favor, stop shopping and contact Foam South now. Highly recommended

Foam South did an amazing job with our shop garage. Ryan provided several options to consider, itemized pricing, and additional details and explanation which was helpful. He was also very flexible and understanding when we had to reschedule twice due to unexpected construction schedule delays and got us back on the schedule immediately once we were ready for insulation. The spray foam crew was very friendly and professional and did an amazing job. The thermal barrier paint crew the next day was also extremely service-oriented and very accommodating, working to mix the paint color on-site to what we expected after it was discovered the wrong color had been sent out and the manufacturer discontinued the light gray. They mixed the perfect color and we are so happy with how it turned out! I highly recommend this company!

I just had my attic and crawl space encapsulated. Foam South was great to work with. The sales process was smooth. The install crew showed up on time and did a great job. The foam is deep and covers roof joists completely. The crawl is clean and well sealed. I’m happy to have all fiberglass removed from the attic, and I can already tell the AC runs less upstairs.

Frequently Asked Questions — Spray Foam Insulation in Roswell

Does spray foam insulation work well in hot dry climates like Roswell?▼
Yes — spray foam is highly effective in hot dry climates like Roswell, 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 Roswell?▼
In hot dry climates like Roswell, 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?▼
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.
