When buying an older home, or remodeling a home, you might consider taking a look at the insulation. Insulation can last decades when properly maintained, but like everything else, it will eventually wear out and need to be replaced.

Valley Insulation will answer some basic questions about old cellulose insulation and what to do about it.

What is cellulose insulation?

Cellulose insulation is made from shredded, recycled materials, and is a form of blow-in insulation. Blow-in insulation is a loose form of insulation that is “blown into” the wall, as opposed to insulation that comes in pre-formed batts. It is easier to install and can cover a large area.

How long can you keep old cellulose insulation?

Cellulose insulation can last anywhere from 20 to 30 years, as long as it has been properly maintained and not been damaged in any way by water, mold, animal infestation, or fire.

Insulation that has gotten wet and is not thoroughly dried can produce harmful mold, and that mold can spread. Insulation that has been damaged in other ways may no longer properly insulate your walls or attic, and you may find it harder to control temperatures.

How do I know if my old cellulose insulation is still effective?

If you don’t know the exact age of your old cellulose insulation, a good way to tell it is losing its effectiveness is an increase in utility bills. If you notice that you are having difficulty keeping your home properly cooled in the summer or properly heated in the winter there is a good chance your insulation needs to be replaced.

How do you remove old cellulose insulation?

Removing and replacing old cellulose insulation cannot be done by hand, and will need a high-powered vacuum to suck the loose insulation from the wall or attic. Professionals usually have the proper equipment for this and are trained in removing the insulation quickly and without leaving a large mess.

If you are having professionals remove the old cellulose insulation they will properly prepare the area to have the new insulation blow in, saving you time and money.
