What work will be done to my home?

A weatherization specialist will perform an inspection on your home and will work with you to determine the best energy conservation measures for your home.  

Typical weatherization improvements may include:

• Insulating attic, walls, floor, water heater and exposed pipes
• Providing ventilation fans - electric, attic, ceiling or whole house
• Installing weather stripping, caulking around windows and doors
• Protecting insulation measures through minor repairs
• Tuning up or repairing heating unit
• Testing for indoor air pollution, mitigating problems and providing information about indoor air quality

*It is important to note that all weatherization work is subject to program and funding availability.

How do I apply?

Clark County has partnered with Clark Public Utilities to administer the weatherization portion of the Low-Income Home Energy Assistance Program (LIHEAP). The utility portion of the program provides you with a grant towards your energy bill.

To qualify for weatherization assistance, you must first qualify for the LIHEAP program. To set up a LIHEAP appointment, call the toll-free number at 1-855-353-HEAT (4328).

During your appointment, let the intake representative know you are interested in the weatherization program. Your information will then be passed onto our office and we will reach out to you to schedule a weatherization appointment.

Visit Clark Public Utilities website at ClarkPublicUtilities.com for more information on energy assistance and the application process.

Stand-alone heat repair assistance

In addition to weatherization assistance, the county also administers two emergency heating system repair programs, one for electrically heated homes and another for natural gas heated homes.

To apply for these programs, contact Clark Public Utilities customer service by calling 360.992.3000. Notify the representative that you need emergency heat repair assistance.
