Doorbell Installation questions, answered by experts

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

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.
