Originally reached out to get an estimate to add some fill in the attic. Came next day, got the estimate. I was happy with it so I got it scheduled asap. They were very polite via email, phone, and in person. I was given a window on arrival time and got a call ahead when they were on the way. Super quick! Highly recommend

The team at All Florida Insulation not only did a stellar insulation job but saved us from years of additional heartache by catching that our roof was still leaking. Long story! Their attention to detail allowed us to get that nonsense fixed and they came back out to finish the job for us once the repairs were made. They also recommended changes to our dehumidifier set up and worked with that company to make sure everyone was on the same page. Our house is holding temperatures like a champ now. We'd use them again in a heartbeat.

They are the real deal. Chris went out of his way to drive to my house and check our insulation. He was friendly, honest, and didn't push any services. At the end of the day, what I initially requested couldn't really be done, and Chris explained the reasoning why. Added bonus, they never pushed me to leave a review (like so many businesses do now). Thank you again all, if I ever need any insulation services in the future you will be my first contact, and I'll always recommend you guys to family and friends. Cheers!

Leo, Javon and Josue did an excellent job reinsulating my attic. My house was built 25 years ago and needed to be updated. They installed new airflow baffling to accommodate the additional insulation, resealed the AC ductwork and sealed gaps in the top plates. All for a reasonable price. Thanks to Derek and Capstone.

Ray Santana★★★★★4 months ago

Leo and his coworker did a great job. Derek came out and walked us through the steps that they would perform for the job from start to finish. They provided pictures of the finished work once completed. Definitely will recommend them for anyone that’s looking to insulate their home.

Derek was very professional and explained everything when he came to check our attic and give me an estimate. He answered all my questions and gave me a lot of confidence. I had already read many reviews here, but I had my doubts. Derek and his team showed me why they have so many good reviews. Their work is excellent. Yesterday, Leo Montilla and Tylor Cruz arrived at our house early, explained the entire procedure, answered my questions, took their time, and in the end, cleaned everything up. Very professional and respectful. I definitely recommend them.

⭐️⭐️⭐️⭐️⭐️ 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!!!

Paul “Indy” Little★★★★★7 months ago

From the moment I connected with Tom over the phone to seeing his team drive off after completion of our project, Tom and his team were communicative, easy to talk to, pleasant, asked what we needed - then explained how they would meet those needs, and came in with quotes that were better than competitive for our multiple projects. In our office space, they completely walled off the area with plastic sheeting to contain the space, while covering the cubicles and floor to protect, and then dispose of any overspray. In our garage project they also delivered on every front with a great attitude and thorough work.

Billy Waters★★★★★2 months ago

Florida Energy Solutions exceeded our expectations with their exceptional service at our facilities. The technicians demonstrated professionalism and respect throughout the project, taking care to properly cover and protect all areas before beginning work. Their efficiency was impressive—they completed the job quickly while maintaining the highest safety standards. What truly set them apart was their attention to detail and customer service. After completing the installation, they ensured I was completely satisfied with the results and took the extra step of thoroughly cleaning the entire work area. Florida Energy Solutions offers competitive pricing and delivers outstanding quality. I highly recommend contacting Travis if you're considering spray foam insulation for your home or business. This company has earned my trust and recommendation.

Scott Mcabee★★★★★2 months ago

We have used Florida Energy Solutions twice for both closed and open cell installs. Tom has always been on time and delivered as promised. His crew is first class all the way. I will keep their phone number on speed dial for future projects. Thank you!!!

Sandy Nelson-Tittsworth★★★★★a year ago

Since foaming block walls April, theHouse is still cool with 90 degrees outside 80 inside still no AC turned on!! Normally, the walls would be radiating 90° with the temperature gun measurement. Was it pressed with the cleanup of the installation crew and the patching went well. We would highly recommend anyone foam their block walls.

We had an excellent experience with Vincent from US Insulation Orlando. They provided us with a detailed review of our attic to determine how we will be able to save on heating and cooling. Their communication was excellent and we were kept informed during every step of the process. Vincent provided pictures of the attic before and after the Insulation. Their customer service is top tier because they value their customers. The pricing is very reasonable. Vincent and his crew were professional and on the day of service, they arrived on time, protected our property, performed the job quickly and cleaned up before they left. We are extremely pleased with the outcome of the attic and recommend them 100%. Get a quote from them before you make your decision.

Once they finish the job, they took the time to clean everything and they show me the pictures of before and after and answer all my questions. I will recommend them to my friends and neighbors.

Frequently Asked Questions — Spray Foam Insulation in Sanford

These are the questions Sanford 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 Sanford contractors above for exact quotes.

Is spray foam insulation a good choice in hot and humid climates like Sanford?▼
Absolutely. Hot and humid climates like Sanford, 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 Sanford?▼
In hot and humid climates like Sanford, 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 Sanford?▼
Yes — significantly. Air conditioning accounts for the majority of energy costs in hot climates like Sanford, 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 Sanford, FL?▼
In Sanford, 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 Sanford costs $2,000–$6,000. Most Sanford 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 Sanford, FL?▼
When searching for a spray foam contractor in Sanford, 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 Sanford 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 Sanford 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.
