What Our Customers Say

Cardinal Insulation did an outstanding job on our attic. They showed up on time, explained everything clearly, and finished the whole job in one day. Our FPL bill dropped by over $120 the very next month. Highly recommend to any Jupiter homeowner.

I got three estimates and Cardinal was not the cheapest, but they were the most thorough. They found air leaks the other contractors missed and sealed them before adding insulation. The difference in our upstairs temperature is remarkable.

We had old, damaged insulation that needed full removal. Cardinal handled the whole process — removal, sanitization, and new blown-in — in a single day. Professional crew, clean work, and the attic looks better than it ever has.

Very impressed with the professionalism. They were careful with our home, protected all the floors and furniture, and cleaned up completely. The estimate was accurate to the penny. Will use them again for our second property.

I was skeptical that insulation would make such a big difference, but my AC runs noticeably less and my house stays cooler longer after they finished. The crew was friendly and efficient. Great local company.

Used Cardinal for a new construction project. They coordinated perfectly with my framing crew, showed up exactly when scheduled, and the work passed inspection first time. Will be using them on all my future builds.

The free estimate was thorough and honest — they told me I only needed a top-up, not a full replacement, which saved me money. That kind of integrity is rare. The work was done quickly and the results speak for themselves.

We've been in our home for 20 years and always assumed the high electric bills were just part of Florida living. After Cardinal upgraded our attic insulation, our bills dropped by nearly $200 a month. Wish we had done this years ago.

Excellent experience from start to finish. The estimator was knowledgeable and not pushy at all. The installation crew was clean and professional. I've already referred two neighbors.
