"My consultation with Stellar was scheduled within a day, met with Patrick on 5/1/25. Time was taken to understand the process, everything that is involved and what my options were. Time was taken to listen to what we wanted/didn’t want and thorough explanation given of the entire process. On 5/2/25 Stellar contracting called to review details and confirm our choices. On 5/5/25 Stellar scheduling called and full installation scheduled for 5/9/25, completed 1 day! The crew and project manager, Cisco, were fabulous to deal with on the install day and even after. A link was provided where we could see pictures of the whole project as it happened. Cisco was readily available on install day and even after with questions and concerns. It was obvious that Cisco did care about the roof we were getting and took pride in the quality of the job that was done. The crew paid good attention to the clean up, there was a lot of debris all over the place. Looking forward to future business with them!"

Insulation questions, answered by experts

Yes, including recycled denim and cellulose from natural fibers.

Rigid foam insulation boards are one of the best insulation materials for crawl spaces. This material insulates the home well, resists water damage, and won't settle like fiberglass or cellulose. Closed-cell spray foam insulation is another effective insulation that both seals the air and provides excellent thermal protection for hard-to-reach spaces like crawl spaces.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

While more is seemingly always better when it comes to energy efficiency, your house does need some interaction with its environment. Adding too much insulation can affect your home's ability to breathe. Breathing simply means ventilating itself to reduce accumulated moisture within it. Too much insulation can physically block the venting ability or be enough to trap the moisture and damage the insulation or the house.

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.
