"I had an excellent experience with this insulation company and their crew. From start to finish, they were professional, timely, and extremely organized. They explained all my options clearly, offered fair pricing, and followed through on everything they promised. The crew worked efficiently, respected my home, and completed the job exactly as scheduled. They also helped me secure an FPL rebate, which was a huge added benefit and showed how knowledgeable they are about available energy‑saving programs. Overall, the service was smooth, honest, and high‑quality. I highly recommend them to anyone looking for reliable insulation work."

"I would definitely recommend this company to anyone needing their fireplace and chimney cleaned. I was very surprised with his thorough inspection of our fireplace and the recommendation he made to seal the cracks in the fireplace. Once he completed the job, everything was amazing; and there was no dirt or ash left behind. He was awesome"

"I was not sure what was wrong so I called these guys, described what I knew, and they said they would come look at it. They said there was an $85 minimum charge for an assessment but that it would be credited toward any kind of services and equipment that I needed. They showed up within 2 hours and even called me ahead of time to double check that I would be there. Once they arrived they checked several things before opening up the unit and then showed me where the electrical part of the system had melted, likely due to a power surge. So it had to be replaced, but they said they could replace the whole system (inside, outside and thermostat) that day. They even got a crane because the outdoor unit is on the roof of my condo unit. The techs were all quick, polite and respectful. They also helped provide photos and documentation should we need to submit a claim to the homeowners insurance company. I would highly recommend them and would use them again in a heartbeat. Big thanks to Alex Rodriguez and his team."

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.
