Q: Should I remove old cellulose insulation before installing new insulation?

• <div><p>Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there&rsquo;s no need to remove it before adding new insulation on top of it.

Q: Is it worth it to insulate basement walls?

• <div><p>Insulating your basement walls offers numerous advantages that make the project well worth it.

You'll also add comfort to the space by reducing temperature swings and increasing your home's energy efficiency, potentially reducing your energy bills to earn your investment back.</p></div>

Q: Is doubling up insulation a good idea?

• <div><p>Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half.
