We identified Rite Way through a Google search and we are sure glad we found them! They topped off our cellulose insulation in our attic and from start to finish they did an awesome job! Our main contact, Nick, first came to our home to inspect our attic and he explained in detail what he saw and provided several recommendations and then he provided a competitive quote. After setting up an install date Nick was the main installer so we felt super comfortable that we were going to get exactly what was described in their quote. Nick was super attentive to detail at every step and after they completed the job I did a full inspection of the attic and it looked great and was fully covered in insulation (see pic) as promised including a very challenging hard to access area that the original builder never filled correctly. My heater is not running constantly now so we are super excited to save on our energy bills :). By far the best customer service from a contractor in the past two years and we have had over 10 contractors working on this old house.

The process was very seamless for us and super quick. They came by and gave me an estimate on the spot, once I reviewed and paid, they scheduled me for just a few days later (the next week). They sent me texts to let me know when they were coming and were on time. They got to work while I was on a call which I appreciated so they didn’t wait on me. They had me check everything after they were done. They even taped up some duct work tape that was falling down. And cleaned it all up. And were faster than I thought they’d be too which is always a bonus. Nice group of guys too. Very happy with the work.

Great group to work with. Mark came out to the house and walked us through the entire process and all our options. We received our quote as promised and were provided several options from which to choose making it easy to stay within our budget. James and the install team arrived early. They were courteous, professional and extremely respectful of our home during the entire install process. After everything was done and cleaned up, James and I inspected the attics - over garage and over house - so I could see everything they did. I would highly recommend Mark and the Insulation Commandos Team.

We recently had Insulation Commandos remove our existing blown-in attic insulation, air sealed all air-gaps, and blew in new insulation with a higher R-rating. We even had them install a radiant barrier for extra goodness. It has been several weeks since install, and the difference has been night and day - especially upstairs, where our upstairs HVAC now runs less and the temperature stays much more comfortable. Mark and his team were extremely friendly, professional, and accommodating - even when it came to working with us on payment for their services. They also kept us updated on their progress and took the time to explain what they were working on, which we really appreciated. Overall, the experience was fast & smooth, the results are noticeable, and the team was great to work with. Highly recommend Insulation Commandos of North Atlanta!

I can’t recommend the Bird Family Insulation team enough. They were prompt, professional, and extremely friendly. We called them because our newborn’s nursery was consistently 3–5 degrees colder than the rest of the floor. After hearing our concerns, they thoroughly inspected and triple-checked the area above the room to ensure it was fully sealed and properly insulated. Once the work was completed, the nursery now holds temperature exactly as it should. Despite the inherently messy nature of insulation work, they left the house spotless. They were a great team to work with, and we will absolutely use them again in the future.

Katrina Trivers★★★★★a month ago

Hired Bird based on several neighborhood recommendations and we couldn't be happier. They were prompt, professional, explained everything clearly and gave us options. They weren't pushy at all and based their recommendations based on what was best for our house.

Thomas Butler★★★★★a month ago

I couldn't be happier with the spray foam insulation work completed by Beau and Bird Family Insulation. They were punctual, professional, and incredibly responsive throughout the entire process. The crew kept the work area remarkably clean, which I really appreciated. The results speak for themselves: we noticed an immediate improvement in our home's comfort and temperature control. The difference in our conditioned space is remarkable. I would absolutely use them again for any future insulation needs and highly recommend them to anyone looking for quality work and honest service. Five stars all the way!

The service from Authentic was exceptional. From the initial consultation to the final installation, the team was professional, knowledgeable, and respectful of the home. The process was clearly explained, all questions were addressed, and the work was incredibly efficient. The quality of the spray foam insulation in the attic is top-notch, and a significant improvement in the home's comfort and energy efficiency has already been noticed. This company is highly recommended for insulation work!

⭐️⭐️⭐️⭐️⭐️ “Authentic Insulation Smart Solutions exceeded my expectations in every way. Their team was professional, courteous, and very detail-oriented. They took the time to explain the best insulation options for my home and made sure the work was done right the first time. I noticed an immediate difference in comfort and energy efficiency, and my HVAC doesn’t have to work nearly as hard now. Honest pricing, quality work, and excellent customer service — I would highly recommend Authentic Insulation Smart Solutions to anyone looking for reliable insulation services!”

Had to leave a review!! What I really enjoyed was how well they explained the process and the benefits of having it done. Never felt like I was being handled, or that they were trying to "up sale " me to make more money. I really appreciated that, keep up the good work guys!!

Great job!!! Re- insulating the attic and outside walls has made a difference. Tony was an exceptional sales person. Knew his facts and showed us why we needed to have the attic redone. The install team was also great. Quick, efficient, and cleaned up after themselves. Definitely would recommend.

Kile Williams★★★★★2 months ago

USA Insulation was great from start to finish. Alex came out and listened to our issues and assessed what we needed instead of trying to sell like other insulation companies. Then Daniel & Felix did a incredible job with the install and wrapped it up by thoroughly explaining the work that was done (with pictures). These two went above and beyond and were great to work with. This was all made possible with Beth helping in the office. This group worked as a team to make our house more efficient and comfortable. Thank you again to the USA Insulation team.

Catina Jeffrey★★★★★2 months ago

New to the area and googled insulation and by the grace of God, Alex was the person that came out to do my consultation free estimate. He was fabulous very knowledgeable. Never tried to up-sell me explained everything and why I would need what I needed. He is a great asset to the company wonderful young man. It feels really good to work with good people that love what they do and are honest about prices.

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!!!!

Mary Webb★★★★★a year ago

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.

As a project manager for a structural steel and erection company, GA Fire Proofing helped me out of a major issue that could have become very time consuming and expensive. However, with their help and expertise, we were able to work through the issue with very little cost or delay to the project. I could not be happier with their service!

Rite Way Instulation is amazing. They did quick, high quality work. The guys were all very nice and professional. Our attic looks amazing and we couldn't be more pleased. This was by far a great experience. They keep us up to date on each thing they did in the process. They sent us pictures frequently and asked us often if we had any questions. We want to thank them for an awesome price and responsive time. We will definitely be recommending them to our friends and family.

Frequently Asked Questions — Spray Foam Insulation in Marietta

These are the questions Marietta 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 8 verified Marietta contractors above for exact quotes.

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