Add Insulation to an Attic

Q: I’d like to add more insulation to the attic but I’m concerned about the installation cost. Is blowing fiberglass or cellulose insulation into an attic a job for a DIY’er or something I must pay to have done professionally? Are the machines available for rent?

A: You can add your own insulation. In fact, you can purchase bags of loose-fill fiberglass or cellulose and install by hand, if there’s not much you need to add. If you do have a big job ahead of you, then blowing machines can usually be found at the same place you purchase the insulation. You may have to rent them (or at least post a security deposit), but in some cases you may be able to use the blower at no additional charge to what you pay for the insulating material.
