what is weatherization?

Weatherization is a process to protect your home from the outside elements and improve its energy efficiency. It will help your house stay warmer in cold weather and cooler in hot weather, all while reducing energy usage. Weatherization will also help prevent any costly damage from water, moisture or even sunlight.

what does it mean to weatherize a home?

Weatherization improves the comfort level and energy efficiency of your home. Weatherization is essentially a protective shield around your home that helps keep the home comfortable regardless of the season. It will also reduce the cost and burden of energy waste that comes with poorly insulated or “leaky” houses.

install duct insulation

Insulation that is installed will help keep unwanted air from entering your home. Not only making your home more comfortable but also helping your indoor air quality. 

repair leaks in heating and cooling ducts

Leaks in your heating and cooling ducts will raise your energy bills because your indoor air temperature will fluctuate. This causes your heating and cooling system to work harder shortening the lifespan of your system. 

perform air sealing

Air sealing is a necessary step in weatherization. Installing new insulation won’t help keep your home more comfortable or reduce your energy costs. This is because the air that leaks out of your ducts is the hot air or cool air in your home that you use to keep the temperature in your home comfortable. Air sealing will prevent drafts inside your home. 

install insulation where needed

We always recommend replacing all existing insulation if it is older than 2015. This is because before 2015 insulation was manufactured with a formaldehyde chemical which is a hazardous material. Also, older homes usually have insufficient insulation, it could be due to damage but also because the code and regulations have changed over the years, meaning your home is most likely not up to code.  

repair roof leaks before installation of attic insulation

It is highly recommended that you check for any roof leaks before installing new insulation in your attic. Without repairing any leaks this can damage new insulation and wet insulation can lead to mold and mildew.

Weatherizing your home has multiple benefits. The main goal is to create a more energy efficient. Not only will it save you money on your energy bills, but it will also generate energy and nonenergy benefits for the community. 

The biggest energy waster in your home is caused by lack of whole home weatherization

why is weatherization important?

Be wise, weatherize. Weatherization is a worthwhile investment that offers many benefits, including saving homeowners up to 20-30% on their utility bills. Our goal is to make each home more comfortable, healthier, and less wasteful by weatherization upgrades.

The federal government and Washington State offer weatherization programs, which Commerce runs, for qualified low-income households. For general information on what the Weatherization Program provides, please see the Client Education Guide (PDF)/Client Education Guide – Spanish (PDF).”
