Weatherization Assistance Program (WAP)

The purpose of WAP is to increase the energy efficiency of homes owned or occupied by low-income persons, reduce their total residential expenditures such as heating and cooling bills, and improve the health and safety of families.

Weatherization is the process of making your home more energy efficient, thereby reducing energy usage and costs. Some of the more common types of weatherization include: sealing the holes and cracks around windows, doors and pipes, ensuring proper levels of insulation, fixing or replacing windows, putting an insulated blanket around your water heater and making sure your heating and air conditioning systems are working properly.


Weatherization services can help a family struggling to make ends meet reduce their energy consumption by up to 35 percent, saving them more than $400 on their heating and cooling bills in the first year alone.

How much you could save from weatherization depends on many things, including your local climate, how much repair your home needs and your local utility rates.  


Answer the following questions to see if weatherization might be able to help you:

  • In the winter, do you feel cold drafts coming from your windows and/or doors, even when they’re closed?
  • In the winter, do you run the heater all day just to stay warm?
  • In the summer, do you have to keep your air conditioner always on all the time?
  • Are your heating and cooling bills way too expensive?

If you answered “yes” to any of these questions, your home may benefit from weatherization services.


 Nearly 60,000 Low-Income Homes Made Energy Efficient

On National Weatherization Day, CSD announced that nearly 60,000 low-income homes have been made more energy efficient around the state under the American Recovery and Reinvestment Act (Recovery Act) Weatherization Assistance Program.

The Recovery Act provided $5 billion nationally to the U.S. Department of Energy (DOE) weatherization program, of which California was awarded $185.8 million. With these funds, California was able to serve 59,066 low-income homes as of September 30, 2012 – three months before the end of California’s grant term.

CSD partnered with 40 nonprofit and local government providers to deliver weatherization services to low-income households around the state. A breakout of homes weatherized by local service provider and county service area can be found by following this link: Statewide Homes Weatherized Breakout

The Sacramento nonprofit Community Resource Project weatherized the family home of Mr. Lenard Scott. Before receiving weatherization, Mr. Scott and his family could not use their home’s heating and cooling system, as it was in bad disrepair and was causing a carbon monoxide hazard. CRP replaced the home’s heating and cooling system, installed attic insulation, a new thermostat, low-flow shower heads, energy-efficient lighting, replaced a window and performed duct repair and home envelope sealing.

“Thanks to this program, I'm not afraid of the cold winter months,” said Mr. Scott. “This program made a big difference in mine and my family’s lives. I haven’t had a working heater in my home for a long time, and now we can live more comfortably in our home.”

Weatherization is a long-term solution to reduce the high energy burden faced by low-income families, who can pay significantly higher portions of their income on residential energy costs. Studies show that lower income households spend significantly more of their total income on their energy bills than other households. An Oak Ridge Nation Laboratory study found lower income households can spend over four times more of their income on energy costs than higher income households.
