"This was an amazing process which I was anxious about doing. Everything went smoothly and it was done in a timely manner. David was professional and he explained the process. His team worked hard . Plastic liner was laid down to protect the carpet. The old insulation was taken away. An estimate was given. I had to reschedule the cleanup date; there was no problem."

"I have only glowing things to say about our experience using Home Genius Exteriors. From the thorough initial estimate and comprehensive inspection of the worksite and what the job would entail to the final bit of blown-in insulation, our multi-team project was completed to our satisfaction in a timely and professional manner. In the course of four days, we had a new roof, new trim, new gutters, and new insulation. Each part of the project required a different team. Each crew finished their task within the projected timeframe. Home Genius coordinated everything, including ordering and delivering the materials and arranging for the delivery and removal of the dumpster. Thanks to our Project Coordinator Ivan, every step in the process went smoothly. He arranged for workers to be at our home on consecutive days: we did not have any time in between steps waiting for availability of the next team. Ivan kept us informed of progress at every step of the way."

"I highly recommend this company for any type of insulation work. The salesman gave a very thorough presentation on all the available options for me, along with a rough estimate at the end of the meeting. I went with the option of removing & installing new rolled insulation (R30). The crew arrived on the scheduled installation date and got right to work. Sealed off everything properly, removed the old insulation, cleaned & cleared out the space, and then installed the new insulation. It was all completed in about 4 hours. I was very impressed."

Insulation FAQs, answered by experts

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

The R-value is a rating that measures an insulation's thermal resistance—in other words, how well it insulates. A higher R-value provides more protection for your pipes, and all pipe insulation materials should have an R-value listed on the product description or label. Each insulation type has its own R-value, which typically falls between one and five for most pipe insulation. When making a selection, Energy.gov recommends choosing a pipe wrap that is at least one inch thick, and the International Code Council (ICC) suggests choosing a material with an R-value of at least 3.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.
