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.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

Upgrading insulation offers several benefits, including improved energy efficiency, which leads to lower heating and cooling costs. It also enhances indoor comfort by regulating temperature and can provide noise reduction. Additionally, better insulation has a reduced environmental impact and can increase your home's value and overall livability.

When installing board and batten siding, make sure there is wall sheathing and a moisture-resistant barrier installed. Behind that sheathing should be plywood or OSB for you to nail the boards and battens into. If there isn’t plywood or OSB, you can install vertical furring strips at 1½- to 2-foot intervals to nail the boards and battens to.
