"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

Durable materials suited for climate include aluminum for coastal areas or composite wood in varying environments for durability and minimal upkeep.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

Garden blankets and frost cloths are the best things to use to protect trees and plants from frost. They are made from polypropylene fabric, which is lightweight, breathable, and dries fast. If you can’t get garden blankets or frost cloths before the freeze, you should use lightweight blankets, sheets, or towels.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.
