Weatherization

Boost energy efficiency: Financial assistance for low-income homeowners and renters

The Weatherization Program offers cost-effective energy efficiency and related repairs to reduce energy bills and increase home health, safety and durability. The Department of Commerce allocates federal and state funds to local agencies who specialize in insulation, air sealing, ventilation, and more to ensure your home stays cozy in the winter and cool in the summer.​

Does my household qualify for weatherization assistance?

Are you looking for ways to lower your energy bill? Maybe you’re looking to reduce your carbon footprint. Whatever your motivation, we’re here to help. Weatherization is available to Washington state homeowners and renters who make up to 200% of the federal poverty level (200% FPL) or 60% of the state median income (60% SMI). Use the following charts to determine if your household qualifies for assistance and see the 2024 Eligibility Guidelines (PDF).

How to apply for weatherization

Once you’ve determined you are eligible for assistance, contact your local weatherization agency listed below to be qualified and accepted into the Weatherization program.

Understanding the application process

If your household qualifies for weatherization assistance, a local certified professional will conduct a comprehensive energy audit to identify updates to your home that will lower your utility bills. When your audit is complete, your local weatherization agency will use cost-effective calculations to determine which upgrades will have the biggest impact on the efficiency, health and safety of your home.

Weatherization work

• Insulation – Ensures your home has a proper thermal boundary, similar to how a blanket retains warmth. ​
• Weather stripping – Seals the cracks in doors and windows to get rid of the draft. ​
• Air sealing – Seals major air leaks from the attic, basement and other drafty areas. 
• Ventilation – Gets rid of moisture in the air from the kitchen and bathroom. 
• LED light bulbs – Uses a fraction of the energy with CFL or incandescent bulbs. ​
• Smoke/carbon monoxide detector – Keeps your home safe from elevated levels of harmful contaminants. ​
• Hot water and HVAC – Ensures your systems are working properly and efficiently. ​
• Healthy home education – Learn best practices for maintaining and elevating your home’s health and safety. ​

Please note: Weatherization is not a window replacement program. We cannot guarantee your home will be eligible for specific upgrades.
