"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."

Insulation questions, answered by experts

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.
