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!

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.

Koala was fast and professional. This company showed up on time and performed a very thorough job of re-insulating our attic. We are already noticing an improvement in the temperature upstairs. Highly recommend.

Pam Browning★★★★★3 months ago

Koala Insulation did a great job for us! Good communication during the estimate process, and they were able to get to our job quickly. They removed all of the old blown-in insulation due to the old owner of the home having extensive animal activity in the attic. They then disinfected the attic, air sealed all of the attic penetrations, and blew in all new insulation. The crew did a fantastic job, worked quickly, and cleaned everything up. They had me check that everything looked great before the closed the attic up. We would highly recommend them! Great company, and a job very well done!

Michael Paisis (PofC)★★★★★a year ago

ABSOLUTELY INCREDIBLE SERVICE! I contacted epic spray foam to insulate my new 2400 sqft garage. They showed up and completed the whole job in 1 single day. They were super accommodating in every way. My new building has zero echo in it and already dropped the temperature almost 10 degrees from the day before insulation! 10 out of 10 recommended

Curtis Nolte★★★★★3 months ago

EPIC Spray Foam was fantastic to work with. Super responsive, very knowledgeable. Its been about 2 weeks since we had our install and we can already feel the results both in the air and in our energy spend. If you're struggling to keep your upstairs cool during the hot summer months, look no further than EPIC Spray Foam. They have also been really responsive with me, after the fact, as I submit the paperwork for GA Power rebates. Could not recommend more.

Paula Goddard★★★★★3 months ago

Epic Spray Foam was professional every step of the way, and they did exactly what they said they would do! They removed all of the old insulation in our attic, sanitized, and installed spray foam. Wow what a difference!! Our attic went from being 130+ degrees in the summer to ~78 degrees!! I highly recommend Epic Spray Foam—-their honest approach, top rated product, and attention to detail is second to none!

2nd time customer. We are very satisfied the Silver Lining Sprayfoam. Price is fair and service is great. They spray foamed our attic a few years ago and we called them again for our new metal building. Jeff was super nice and helpful with questions. It looks great! They were very conscientious of my “toys” that we could remove and they covered everything up and there was no issues and no mess. The guys were super nice.

Chris Woodson★★★★★4 months ago

I recently had Silver Lining Sprayfoam insulate my attic, and the experience was phenomenal. They scheduled my install quickly and came highly recommended. The crew arrived on time, explained the plan clearly, and worked efficiently—completing the job within hours and exceeding expectations. If you're looking for high-quality attic insulation delivered by a professional, efficient, and courteous team, Silver Lining Sprayfoam is the company to call.

Ben Kightlinger★★★★★4 months ago

We had 2 very large attics that cover most of our house done by Silver Lining. They did quick, clean, efficient work in getting the job done despite it being a very large space. Our upstairs feels noticably less muggy on very hot days which is fantastic, and our first energy bill showed a noticable decrease from prior comparable months. To their credit, we did have a couple small areas of ceiling drywall that got damaged in the process, and the owner followed through and ensured these were fixed and looking like new. Overall we are very happy with the job they did.

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.

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 Duluth

These are the questions Duluth 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 9 verified Duluth contractors above for exact quotes.

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