Weatherization

Weatherizing your home will improve its efficiency. You'll use less energy on the same activities, reducing your home's carbon footprint and saving you money over time. Weatherization also allows electric heating equipment to operate more efficiently.

Weatherization reduces heat loss in your home. Usually, weatherization includes insulation, air sealing, and window projects. Sometimes it also includes ventilation projects to make sure the house has good air flow after it’s been sealed better. These activities reduce emissions, lower energy bills, and improve comfort throughout the year.

Insulation

In climates like Minnesota’s, insulation is an important part of keeping your home cool in the summer and warm in the winter. A well-insulated home is more comfortable and has lower energy bills. Wall insulation and attic insulation are two common projects, and they’re often paired with air sealing. Insulating and air sealing are the most impactful energy efficiency upgrades you can make to your home.

Air Sealing

When you work with a contractor to air seal your home, they’ll seal gaps and holes that may be leaking air. This can make your home feel stuffy when it’s warm or drafty when it’s cold. It can also affect your home’s air quality, humidity, and efficiency. When your home is air sealed, you’ll experience more consistent temperatures and energy use. Air sealing and insulating are the most impactful energy efficiency upgrades you can make to your home.

Windows

When it comes to windows, many projects are expensive and do not address the main causes of heat loss in the home. We recommend air sealing and insulation projects before replacing windows. If you are ready for a window project, make sure each window has at least two panes of glass. If you have single-pane windows, installing storm windows over them can make them work like double-pane windows.

Ventilation

Having good air flow throughout your home is key to a healthy indoor environment. Without it, moisture and air pollutants can build up, leading to health issues for you and structural concerns for your home. Usually, bath and kitchen fans provide ventilation in weatherized homes. If you’re planning any weatherization upgrades in your home, it’s important to work with a professional to understand and meet your home’s ventilation needs.

Weatherization FAQs

Insulating your home keeps the air you’ve heated or cooled inside, keeping the home more comfortable. This can reduce your energy bills, because you’re not heating or cooling air that escapes the home, and it prevents your heating and cooling systems from having to work hard to address changing temperatures. If you pair your insulation with air sealing and ventilation, you can also reduce mold and moisture risks and improve indoor air quality. 

Air sealing is the process of sealing minor gaps or leaks in the home, like where vents or wires enter or exit the attic from your living spaces. These small leaks are common, but they can add up, leading to discomfort and higher energy use. One way to find areas of air leakage is a home energy audit, which can use a combination of tools like blower doors and infrared cameras to measure and find areas that are leaking. 

We typically recommend working with a contractor for air sealing. Not only is the work technical and messy, but many homes that benefit from air sealing will also benefit from insulation, which a contractor should do. If you have a home energy audit, your report may include information on your insulation and may even have a quote for insulation and air sealing.
