We got our storage space in attic sprayed with closed cell foam. Coastline was one of 3 companies we got quotes from. Lance was our coordinator for a job and estimator. He did excellent in communicating and explaining everything. His response was quick, based on square feet, height and number of walls. Their price was the best out of 3 too! A lot of businesses in the area price you based on how your house looks and neighbourhood it’s located in. I feel like Coastline did a solid honest quote based on amount of work, not the worth of your property. Their guys showed up 8am as scheduled, worked non stop in the hot hot attic till they were finished. They covered all the areas they were walking on, including garage floor. They cleaned up afterwards too. I definitely recommend them and will call only them for my future insulation needs. I do not know personally anyone working in this company and my experience is based on personal interaction and work completed. My advice is to consider them first before anyone else.

I just wanted to rate, and give a short review of the Service and Installation of Spray Foam Insulation in our RV Garage! 5 Stars!! I initially got in contact with Lance at Coastline Insulation thru my builder… Lance was so eager and easy to work with us! Great personal touch, he gave us a comprehensive and competitive cost offer, and was willing to make changes as we discussed different options. Lance gave us a price which was about $500 lower than another competitor. Very soon we were on the schedule, and his professionals were on their way! It was a big job, but they came in, on time, and prepared the RV Garage for spraying by putting up plastic drop cloths, taping up electrical outlets, etc. it took them about 6-7 hours overall, but they cleaned up like they weren’t even there! Thank you Lance and your team! Fantastic! Thank you! Sincerely, Doug

Highly recommend! David and his entire team are amazing! Scheduling with the team was so quick and perfect. They added the recommended amount of insulation in the attic. We noticed a huge difference where it stays cooler for longer upstairs and the AC doesn't have to work as hard. They are very careful while setting up and working and cleaned up right after. So grateful and will always recommend this company!

I highly recommend Green Service Insulation. They did an excellent job in my home removed all the old insulation, installed new insulation, and performed a full sanitization. The work was done professionally, cleanly, and with great attention to detail. I’m extremely satisfied with the results and would definitely recommend them to anyone looking for a reliable and high quality insulation company.

We had a great experience with Atticlean! They are a company with integrity which is hard to find these days. David came out several months ago to give us an estimate on attic insulation. He said he would love to do the job, but pointed out we had some issues with our existing AC duct work that had to be addressed first. He said otherwise, the insulation really wouldn’t perform and provide the benefits it’s supposed to. We really appreciated his honesty! That’s why we called him back to do the job after we had new ducts installed. We just had the insulation blown in a couple days ago and his crew was really efficient at getting it done. They provided us with multiple photos of the attic so we could see the insulation was blown to the agreed-upon height. I am including just three of them here. Overall, a really great experience with David and his company and cannot recommend him enough!

Great company! Assessed the seawall problem, laid out the plan of repair, one week later repaired the 88 foot seawall with precisely placed injection sites every 18 inches. It took the team only 3 hours, yard was in perfect condition when they left. 10 year warranty on the work, proven technology, I am on board with The Foam Guys!

Stephanie Peral★★★★★5 months ago

We had the absolute pleasure of working with Hogan Construction & The Foam Guys !!! They were absolutely incredible. We had a gutter issue that various companies had refused to help us with - and one company had even ghosted us! But they solved the issue expeditiously and with the utmost professionalism. We are happy to experience rainstorms without the same fear of flooding. Thank you so much!!!

Frequently Asked Questions — Spray Foam Insulation in Miramar

These are the questions Miramar homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 25% typical energy savings. Compare the 4 verified Miramar contractors above for exact quotes.

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 Miramar, FL?
In Miramar, 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 Miramar costs $2,000–$6,000. Most Miramar 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 Miramar, FL?
When searching for a spray foam contractor in Miramar, 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 Miramar 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 Miramar 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.
