"Insulation NW did an excellent job of removing old inadequate insulation from an attic and crawlspace and replacing it with new insulation and wrapping the ductwork. They had two crews, one for the attic and one for the crawlspace, working for many hours to complete the job. A vapor barrier was also installed in the crawlspace. We paid a very reasonable price after the large PSE Rebate was applied."

"The entire process from estimating (Kenny) to project management (Walter) to team members (four), was efficient, respectful of our property and extremely communicative. The team went multiple extra steps to make sure our crawl space free of entry points for critters while installing all new insulation"

Insulation questions, answered by experts

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

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.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.
