Kathryn W Hatcher★★★★★a week ago

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!

Aladdin Insulation truly exceeded my expectations. Their fair quote and professional service set the stage for a remarkable experience. Charles, the owner, was not only always responsive but also incredibly helpful throughout the process. Eric and his on-site crew were a delight—friendly, communicative, and always ready to assist. They did a wonderful job, addressing all my questions with expertise. I'm very pleased with their friendly and knowledgeable service, which went above and beyond. Without hesitation, I would gladly refer Aladdin Insulation to friends and family.

Charlie came to the house the day after I called them. He measured and gave me a solid handshake quote on insulation replacement and attic cleaning. The work was done 2 days later and took only hours to complete, and I couldn’t be happier or more satisfied with the service and attention I received from Eric and the in-home team. They removed my old insulation, inspected everything and checked for leaks etc. I highly recommend them. My service was in October 2025.

Matt Keown★★★★★a month ago

Aladdin Insulation did a great job insulating our attic. The guys were prompt, clean and followed through with everything that was committed to from installing baffles in the soffets to sealing plumbing pipes in all bathrooms. It has only been one day, but I can already tell that the insulation is doing its job. I highly recommend them.

Frequently Asked Questions — Spray Foam Insulation in Alpharetta

These are the questions Alpharetta 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 4 verified Alpharetta contractors above for exact quotes.

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