Residential Spray Foam Insulation in Jacksonville, FL

Cooler rooms, lower bills and less humidity for your home, installed by a family-owned crew with the owner on every job.

Spray Foam Built for Jacksonville Homes

Your home’s insulation has a tough job in Jacksonville. Long, hot summers and heavy humidity push into every gap and crack, and your AC pays the price. Spray foam insulates and air-seals in one step, so the cool, dry air you pay for stays inside.

Clark Spray Foam insulates homes across Northeast Florida, from new builds to older houses that have never felt comfortable.

Signs Your Home Needs Better Insulation

If any of these sound familiar, spray foam is worth a look:

Hot upstairs rooms

Second floors and rooms under the roofline soak up attic heat. If upstairs is always several degrees warmer than downstairs, heat is getting in from above.

AC that never shuts off

When cooled air leaks out and hot air leaks in, your system runs constantly to keep up. Sealing those leaks takes pressure off it and can help extend the life of your AC.

Sticky, humid air

Humid outdoor air slipping through gaps makes a house feel clammy even when the thermostat says it’s cool. Stopping that air reduces the risk of mold and humidity problems.

High energy bills

If your bills keep climbing, your insulation may not be doing its job. Spray foam can save up to 50% on energy costs.

New Construction or Retrofit

Building a new home? Insulation goes in after framing and rough-in work and before drywall, which is the easiest time to spray every wall cavity and the roof deck. Learn more about new construction insulation.

Upgrading the home you live in? Spray foam works in existing homes too. We’ll look at where your comfort problems are coming from and recommend the areas that make the biggest difference. If old insulation is damp, damaged or in the way, we can handle insulation removal first.

Where We Insulate in Your Home

Attics

In many Florida homes the AC air handler and ductwork sit in the attic. Foam on the roof deck brings that space inside your home’s envelope. See our attic insulation options.

Walls

Foam fills wall cavities completely and seals the gaps around framing, outlets and windows where outside air sneaks in.

Crawl spaces

Closed-cell foam doesn’t absorb water, which makes it a strong choice for damp crawl spaces under raised homes.

Subfloors

Insulating under the floor keeps crawl space heat and moisture from reaching your living space and makes floors more comfortable.

Bonus rooms

Rooms over garages or tucked into the roofline are often the hardest to cool. Sealing their walls and ceilings brings them in line with the rest of the house.

From start to finish you felt like you were dealing with a small company which in my opinion are the best. On time for their appointments and and seamless paperwork. On the day of installation, they were on time at my house then their crew worked their asses off for 10.5 hours. Left my place just they found it in the morning. I am beyond pleased with the work of this company.

No more wondering what a great spray foam job will do for your comfort. In the months leading up to Clark Spray Foam replacing our attic insulation, peak temperatures in the garage were over 100°. You can only imagine the attic temperatures were at least 15° higher over the entire house. After removing the blown in over just the living spaces and encapsulating the entire attic including the garage and rear porch, peak temperatures in the garage have dropped to below 85°. Surface measurements in the attic match. The whole house feels cooler and we even experience morning condensation on the outside of the windows proving the insulation is doing its job. Clark Spray Foam was prompt, professional and when an equipment failure delayed completing the work in one day, Mike called and scheduled the completion the very next morning.

We had been having major trouble with our brand new AC unit keeping up on really hot days on the second floor. Like having the thermostat set for 73 but it being 78 or higher upstairs. The spray foam installation from Clark Spray Foam has made a huge difference and our new AC unit is working as it should now! Their estimator was great and answered all of my questions and concerns and the guys on the day of the job were very professional. Thank you!

Great staff starting with Sonia who you speak to initially to set up appointments. Then the estimated comes out, think Josh but not sure. Then the two workmen, Malaki and another nice young man. They did a great job at a competitive price. Now, waiting to see improvement in my electric bill. Thanks to all the nice, competent people at Clark’s insulation!

Everyone from this company was very professional and easy to work with. In North Florida I’m used to contractors showing up, fixing something , creating a huge mess and then just leaving the mess in my house. This company was the total opposite!! it was refreshing to have a friendly sales rep and also working with professional office management. The crew did a great job! I am excited to cut back on AC and heating costs with this new spray foam insulation. Everyone was efficient, effective, and reliable.

What a difference spray foam made in insulating our home. In the hottest part of the day, the house stays cool now. We were on the fence between more blown in or spray on. This company knew how much better spray on was as well as the concerns about open and closed cell spray on. Incredibly hot up in our attic and yet they completed the job in two days. I have a lower pitch roof and the 1950 addition had difficult access. We worked together and found a solution to get the job done. I can’t wait to see the savings on my next electric bill. I imagine that i will recover the cost in under two years… if not sooner. I am very happy that I chose Clark spray on!

No matter what I tried my house always felt hot upstairs. Had my attic spray foamed in the summer. I have a large barn style house 5600 ft.² with a cedar lap board ceilings. They removed all of the fiberglass insulation and spray foamed the attic. The employees that I met from the actual sprayers to the laborers and the assistant that came to pick up the check, were all fantastic and personable. Everything did not go as planned, but all of the obstacles were handled professionally and they billed the original contract price. I stayed at a hotel a couple of days, the manufacturer recommends 24 hours dry time.

Clark Spray Foam did an outstanding job insulating both our attic with open-cell spray foam and our crawlspace with closed-cell spray foam. From the first conversation to project completion, their team was professional, knowledgeable, and easy to work with. They took the time to explain the differences between open-cell and closed-cell foam, answered all of our questions, and made sure we understood the process and benefits before getting started. The installation crew arrived on time, worked efficiently, and left the property clean when they were finished. The quality of the work was excellent, and it’s clear they take pride in doing things the right way. We were especially impressed with their attention to detail and commitment to customer satisfaction throughout the project. If you’re considering spray foam insulation for your attic, crawlspace, or entire home, I highly recommend Clark Spray Foam. Great company, great people, and exceptional workmanship.

Clark’s crew did an amazing job! We had an initial consultation and they immediately gave me a quote.. The quote was super fair and better than what I expected. They came in day of install and secured and taped off areas to protect the home from the removal of old insulation. They had a full crew for the job and they were not playing around. These guys got right to it and worked as hard as I have seen people work. They were crawling in tight spaces fully suited in protective gear in 130+ degree attic. My hats off to these 6 guys . I appreciate the hard work. After the job was complete they walked me thru to make sure I was happy with the job. GREAT JOB! you will definitely be a company I refer out. Thank you Robby Mullins

The gentleman doing the job were polite, kept the work area clean, and insured that it was all cleaned when they left. They did Loosen one air-conditioning duct, but it was fixed immediately. Good job!

We are in the middle of a massive mold project and Clark Spray Foam came highly recommended from our new HVAC company. Mike and Austin’s team did a great job on phase 1 of our project. First part is installing unfaced batting in the walls. Attached is an idea of just a quarter of the amount of replacement they did! Lots of angled walls that are a bit awkward to work with and they nailed it. We are excited to start phase 2 with them once our ceilings have been rebuilt! :) I’ll update this review after that part and add more pics/videos!

These guys were truly incredible. They were very professional and they knew what they were talking about. They came over and gave me an estimate. Took only about 25 min. and then the crew showed up on the scheduled day and they did a spectacular job. These guys were incredible. The job itself was incredible and the way they left my shop after was unbelievably clean. I could not believe it. I highly recommend them to anybody that needs this kind of work done.

These guys were awesome. I called 4 companies to insulate my shed. I still haven't heard from one. The other 2 took forever and gave me crazy numbers. Clark called me by the end of the day and met me on site to quote it a day later. The price was better than the rest and he scheduled me on the spot. 8 days from request to final install. The installers banged it out in half a day and cleaned everything behind them. My wife actually went to the shed to make sure they had been on the property. The crew was clean and courteous. The salesman (Austin) called me later that day to make sure I was happy and everything went well. More contractors need to work this way. Thank you Clark!

Overall great experience their 5 star rating is warranted. I emailed for a quote to get my metal building sprayed, I was responded to almost instantly while the other companies I contacted responded days later. They came out next day and provided a detailed quote that was fair. I had a bunch of schedule changes for when I needed the spray to be done and they worked around them with no issue at all. On the day of the spray the guys got here and were all super nice and professional, job looked good, very happy overall will use again if I ever need something else in the future

Residential Spray Foam Insulation FAQs

How do I know if my home needs spray foam insulation?

The most common signs are hot upstairs rooms, an AC that runs constantly, humid or sticky indoor air and energy bills that keep rising. These usually point to heat and outdoor air getting in through the attic, walls or floors. A free quote is the easiest way to find out where the problem is coming from.

Can spray foam be installed in an existing home?

Yes, spray foam can be installed in existing homes as well as new construction. In a retrofit, attics, crawl spaces, subfloors and bonus rooms are common places to start because they’re accessible and often the source of comfort problems. If old insulation is damaged or in the way, we can remove it before spraying.

Which type of spray foam is best for my home?

It depends on the area, and many homes use both types. Open-cell is often used in attics because it’s an air barrier, absorbs sound well and costs less per R-value. Closed-cell doesn’t absorb water and acts as a vapor retarder, so it’s a strong choice for crawl spaces. Read our open-cell vs. closed-cell guide for the full comparison.

Will spray foam make my upstairs rooms cooler?

In most homes, yes, because hot upstairs rooms are usually caused by attic heat and air leaks above the living space. Spray foam on the underside of the roof deck keeps heat from building up in the attic and brings ductwork and the air handler inside your home’s envelope. Results vary by home, which is why we start with a walk-through.

Is spray foam a good fit for a bonus room?

Yes, spray foam is a strong fit for bonus rooms, which are often the hardest rooms in a home to cool. They usually sit under the roofline or over a garage, so heat comes in from several sides. Spraying foam in the walls and ceiling seals the gaps where hot air leaks in and helps bring the room closer to the temperature of the rest of the house.

Do you offer financing for residential spray foam?

Yes, financing is available through Acorn Finance. You can also request your quote online to get 10% off your project. Quotes are always free, and we’ll walk you through the options for your home so you can choose the scope that fits your goals and budget.
