"I had an amazing experience with this spray foam insulation company. From the first phone call, they were upfront, honest, and very knowledgeable. The crew showed up exactly when they said they would and walked me through the whole process before starting. They insulated my attic and part of my garage, and the difference was noticeable the same day ? the rooms stay cooler, and the AC doesn?t run nearly as much"

"Hired A Kool to replace my AC ducts. I received 3 quotes from different companies Company 1 - Good price but told me he couldn?t work from the attic due to lack of space so he suggested I cut holes in the ceiling so he could work from inside Company 2 - Quote 21K ? A Kool - Price was right and I did not have to cut any holes in the ceiling as they did all work from the attic. Crew was very professional, and very thorough in their work. Salesman Promised the job would be done in a day and job was done in a day. Crew showed up at 7am and didn?t leave until the job was done (8:00 pm) Will Hire them to blow insulation in the attic as they found that the attic was not properly insulated. Excellent experience."

"Attic Fanatics did an outstanding job from start to finish! The team was professional, punctual, and explained every step of the process clearly. They removed the old insulation, sanitized, sealed air leaks, and then installed new insulation — everything was done with attention to detail and care for our home. What impressed me most was how clean they left the job site and how much cooler and more comfortable our home feels now. They even shared before-and-after photos so we could see the difference in our attic. It’s rare to find a contractor that goes above and beyond like this. I would highly recommend Attic Fanatics to anyone looking for attic insulation or ductwork — you won’t be disappointed!"

"Aldo and his Team at A Best Insulation were very responsive and did a great job. They were especially helpful in terms of protecting our equipment & furniture and working around our schedules. They cleaned everything up when the job was complete and were very concerned about our safety, during and after the install. We have already noticed a dramatic difference in not having to keep our Air Conditioning set as low as we used to and less humidity in the house has made us much more comfortable! I highly recommend the Spray Foam Insulation done by A Best!"

FAQs for insulation service projects in Key Biscayne, FL

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
