Spray foam insulation contractor that is family owned and local to us here in St Augustine. Very professional and quick. Job site was left perfectly clean. Spray foam insulation was recommended for the space beneath our home to keep out the moisture and air gaps. Also helps a lot with reducing sound and increasing the structural integrity of our manufactured home.

We were having a problem with the plumbing pipes in the attic becoming very hot in the summer. So I called Koala Insulation, after hearing about them from an interview with Carren Reale, on WSOS. Bruce Hammer, with Koala Insulation came out to assess the problem. He combed the attic and determined that we could use some additional insulation, which would help our problem. He also found some areas in the attic where we didn't have any insulation! His estimate was very reasonable so we scheduled the service. His servicemen were prompt and did a wonderful job of adding the blown-in insulation. They were respectful and helpful. They addressed the special areas too. They cleaned up after themselves and even left an old tool which they had found. I would wholeheartedly recommend Koala Insulation to anyone needing insulation!

I can't say enough about the fantastic experience I had with Koala Insulation. Bruce came out and made the entire process of getting my garage insulated incredibly easy. He was professional, knowledgeable, and gave me a clear and honest assessment. If you're considering insulating your garage, I highly recommend Bruce and the team at Koala Insulation. You'll be amazed at how simple they make the whole process!

They had one of the lowest bid on my project, not the lowest but very close. To be honest the quality of the lowest bidder was in question, so I went with Koala. They did a great job. They did experience an equipment failure, it happens, but they handled it perfectly. The company was apologetic and sent double the technicians to get the job done fast. Their technicians were friendly and very professional. I will be using these guys again. I definitely recommend this company.

⭐️⭐️⭐️⭐️⭐️ 5-Star Review for Brandon at Imperial Pest Prevention!!! Brandon did the treatment on my apartment today and truly did an exceptional job. He took his time and sprayed in every area, including spots that might normally get overlooked. His attention to detail was something I really appreciated. I have a dog and a free-roaming ferret with no cage, so I was worried about the chemicals being used. Brandon explained everything clearly, answered all my questions, and made sure my pets were safe. His professionalism and careful approach made me feel confident and comfortable with the process. I actually caught him as he was about to leave and asked if he could spray my unit, and he turned around and came back in without hesitation. His great attitude and willingness to go the extra mile says everything about his work ethic. Imperial Pest Prevention is lucky to have someone who cares so much about each customer. I highly recommend asking for Brandon specifically — you’ll be in great hands. Below is my dog Chloe and my ferret buddy who want to thank Brandon as well for keeping them safe and sound!!!

My air conditioning unit stopped working overnight. I called Attic Man and they quickly had someone out to my home. The tech was quickly able to find the issue. The part had to be ordered but the he was able to get my unit temporarily up and running until it came in, which with my 2 kids is a blessing. They even installed the part the same day it was delivered. Since the technician also took time to answer a few questions I had about my thermostat and the great service I decided to sign up for a maintenance contract. I am glad to see a company and it's employees who still care about the services they provide. Thank you guys for everything.

HVAC company that installed our new AC unit and ductwork made mention that we'd probably do well to have the attic insulation improved. A neighbor had AtticMan, and recommended their services, so I gave them a call. The only issue I had was someone getting back to me, seems when you're good, you're busy :) They worked with me and gave me a decent quote for a full removal of the (50 year??) old dirty dusty insulation and a new blow in of R-38. The friendly cleanout crew arrived on time and worked in a very professional manner. After hours of cleaning up all that old, dirty, dingy insulation, the professional wool-blowing crew was right there behind them, and completed the entre job in no time. Very good work and I would highly recommend them.

Jim Swenson★★★★★a year ago

Every summer, our garage would reach temperatures well over 100 degrees due to the hot attic air radiating down. We finally decided to take action and called Attic Man. The office staff was pleasant and helpful, scheduling the assessment promptly and following up with the installation. They arrived as scheduled, and two hours later, the job was complete. What a worthwhile investment and a great company to work with. Thank you, Attic Man!

I recently had Jim Lovelace and his crew apply spray-on insulation in my new metal garage. After getting several quotes, we chose to work with Jim, and I’m very glad we did. He was extremely helpful throughout the process and worked with our tight schedule to make everything happen on time. His pricing was excellent, and the quality of the work was outstanding. The crew did a fantastic job—the application was clean, thorough, and the cleanup afterward was perfect. The insulation has already made a huge difference in the interior temperature of the garage. I’m very pleased with the results and will definitely use his company again.

airzonextreme★★★★★a year ago

Lovelace did a big residential construction job for us in St Augustine. James has got great crews of men. They did an excellent job for us. I read the bad review, and likely that entire situation was because James was slammed busy. He's a super nice guy and worked on multiple phases of our new build. If you can get on his schedule, then by all means book him.

Highly recommend Lovelace Insulation. James and his team were communicative, efficient, and fair in pricing. They insulated our whole office building. Thank you again!!

Frequently Asked Questions — Spray Foam Insulation in St. Augustine

These are the questions St. Augustine homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 30% typical energy savings. Compare the 7 verified St. Augustine contractors above for exact quotes.

Is spray foam insulation a good choice in hot and humid climates like St. Augustine?▼
Absolutely. Hot and humid climates like St. Augustine, FL are actually where spray foam insulation delivers some of its best results. Closed-cell spray foam acts as both an insulation layer and a moisture/vapor barrier, preventing the humidity infiltration that causes mold, rot, and air conditioning inefficiency. Homeowners in FL typically see 20–35% reductions in cooling costs after installation. One important note: because spray foam creates a tight building envelope, proper mechanical ventilation is essential in humid climates to manage interior moisture from daily activities like cooking and bathing.
What type of spray foam is best for homes in St. Augustine?▼
In hot and humid climates like St. Augustine, FL, closed-cell spray foam is generally recommended for exterior walls, crawl spaces, and attics. Its high density creates a moisture barrier critical in humid environments. Open-cell foam can be used in interior walls for soundproofing and actually allows some vapor movement, which can be beneficial in certain wall assemblies. A qualified local contractor can assess your specific home and recommend the best approach.
Can spray foam insulation help reduce my AC bills in St. Augustine?▼
Yes — significantly. Air conditioning accounts for the majority of energy costs in hot climates like St. Augustine, FL. Spray foam seals all gaps and cracks that allow conditioned air to escape, which is the primary cause of high AC bills. Most homeowners in hot climates report 20–30% reductions in cooling costs after spray foam installation.
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 St. Augustine, FL?▼
In St. Augustine, FL 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 St. Augustine costs $2,000–$6,000. Most St. Augustine 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 St. Augustine, FL?▼
When searching for a spray foam contractor in St. Augustine, FL, 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 St. Augustine 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 St. Augustine 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.
