Alexei was the installer. He was on time, very professional, explained the process and cleaned up when the job was completed. Very personable. My project was the replacement install of an attic step ladder. Would recommend him to my family and neighbors.

Doorbell Installation questions, answered by experts

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.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.

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.
