Square footage of insulation
Type of insulation
Climate in your area and the insulation R-value required
Whether or not your walls are already finished
Accessibility of the area
Whether or not you need old insulation removed first

If you’re a savvy DIYer around the house, own the basic tools, and have enough time on your hands, you can definitely install fiberglass insulation yourself. Doing the work yourself will certainly keep overall insulation costs down. However, if you’re not confident in your handy skills around the house, call in a professional.
