Doorbell Installation questions, answered by experts

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.

It is generally completed in a day, depending on the attic size and access difficulty.

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process.

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.
