"I can compare the recent On The Mark Spray Foam Insulation application to a previous installation by another company. Big difference! This time - all surfaces were carefully sprayed with constant depth, no skimping on product, no dripping all over due to incorrect mixture, clean no-mess job. In my opinion, this contractor is not only On The Mark, but also on-time and on-the-money! Smart use of technology provided me a competitive fair quote on the spot at first meeting and made subsequent billing and bill-paying transparent, accurate, and easy.  The company may not dominate the market yet, but these guys are old hands in the insulation industry with a lot of personal experience plus they are nice and good to work with."  (St. Petersburg)

Excellent company! I was in a rush to get the job done and they were able to complete the work two days after they gave me an estimate.  The crew was fast, efficient and extremely polite!  I would hire them again in a heartbeat!

Quick, easy, gave me a quote over the phone which other companies wouldn't do. I'm a busy person and appreciate the straightforwardness with no bs.

Mark is an All-Star insulator. One of the best spray foam applicators in Florida. If you need your home or building to be cooler, look no further than On The Mark Insulation.

Just had a great experience from this company. From the owner Mark, the foam applicators Phil and Anthony and the extraction guys Justin and team. All very knowledgeable, professional and communicated and kept me up to date constantly. They did what they said they’d do and when they’d do it. I highly recommend them.

On The Mark is amazing. I called for just a quote and not only did they give an amzing price, but also informed me about different ways that I could protect my home from the heat. The crew came out and killed the job in a day. Thanks, guys, I appreciate it.  Electric bill went down 20%.

Commercial maintenance being my background, I asked a few baited questions. The answers were right on. The personnel handled themselves professionally. The job was done on time - perfectly.

Great Job, very professional workers. Cleaned up and it looks like they were never here. They were very thorough and even took a picture of a split in the duct work so I could have it repaired and not air condition my attic.  Highly recommend the company.

Mark and his team were awesome at what they do and listened to my concerns and made sure the installation was as perfect as possible. The insulation outcome is a huge difference in temperature!

Steven Bayly (Brooksville)

Mark Gordos and his team did a fantastic job insulating my attic. They came out and removed the 30 year old blown in insulation in my attic and then re-insulated the attic with new R38 blow in insulation. We could tell the difference right away. My AC unit was not keeping up during the heat of the day, now we have no problems with the house staying nice and cool.  They were very professional and did not make any kind of mess for me to clean up like many companies do.  Thanks Mark, you guys are awesome!
