Doorbell Installation FAQs, answered by experts

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

While not every wall requires a vapor barrier, if you do need one and don’t install it, moisture can get between the walls of your home. This can lead to water damage from mold growth or rot, and the excess moisture could also attract pests, including termites, cockroaches, or ants.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.
