I had Wayne and his guys to blow additional insulation in the attic. I would recommend Armour Insulation. They were reasonably priced, was able to schedule and complete job in a very acceptable time frame and left no mess. I would use them again.

We recently purchased our 30 year old home and during the pre inspection noticed the old attic insulation was missing in spots exposing sheet rock and at its highest was under roughly 6”. Due to this the temp in the home would reach 80 degrees and wouldn’t cool any lower regardless of the AC’s best efforts. I called Armor Insulations and they were very polite and got us on the schedule immediately to come add blown in insulation to the entirety of the attic bringing the insulation within the 10-14” that is required by code. They were respectful and courteous throughout the whole experience and left no trace of their presence other than the insulation installed. Now our home sits comfortably at 74 degrees during the peak of the day. I would highly recommend giving them a call for your home insulation needs.

I recently had Armor Insulation handle the spray foam insulation in my attic, and I couldn't be more pleased with the results! From start to finish, the team was professional, knowledgeable, and efficient. They took the time to assess my attic's needs and recommended the best insulation solutions tailored to my home. The installation process was smooth, and the crew was smooth and the crew was respectful of my space, leaving everything clean and tidy once they were done. I've already noticed a significant difference in the temperature stability of my home, and I anticipate lower energy bills as well! I highly recommend Armor Insulation for anyone looking for top-notch insulation services. Their expertise and commitment to quality truly set them apart. Thanks, Arnor Insulation.

Magnolia installation has the best prices in the pine belt. They came out in a reasonable amount of time to do the work. Their sprayer did an excellent job on my party barn. They came in covered everything up did their thing and were out. Jason was a gentleman that came out and did the cost estimate. He was very easy to work with.

Frequently Asked Questions — Spray Foam Insulation in Hattiesburg

These are the questions Hattiesburg 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 2 verified Hattiesburg contractors above for exact quotes.

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