Doorbell Installation FAQs, 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.

A radiant barrier is a form of insulation topped with a reflective material designed to keep homes cool during hotter months. It is generally considered worth the investment if you live in a hot, sunny climate, as the cost can be recouped over time through lower energy bills. Installation costs typically range from $0.10 to $1 per square foot. After installation, homeowners in warm climates may save between $7 and $15 per month, potentially reducing their electric bill by 5% to 10%. The exact savings will vary depending on your location and the type of barrier chosen.

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.
