Here we go again! Are you ready? We already have some folks up and running with whole house generators or interlock systems to plug in their smaller portable generators in the event of an outage.

You could be ready too! Message us and we’ll come out and give you an estimate.

💨 Wind and Rain Advisory 🌧

Gusty/strong E-SE winds are expected this evening (Monday, December 23) with 45-55 mph possible. Brief, heavier downpours are also possible this evening and could cause water on the roadways especially near clogged storm drains.

Occasional showers increasing to steady rainfall is expected Tuesday through Friday with periods of gusty winds likely Wednesday into the weekend and potentially next week.

Please use caution while driving. Be prepared for standing water on the road. Staff will continue to monitor conditions. Happy Holidays!

As fire season intensifies in Washington, power outages become more frequent and unpredictable. Don't let unexpected blackouts disrupt your life. Ensure your home stays safe, comfortable, and powered with a reliable backup generator or other system. Whether you need to keep essential appliances running or stay connected, a generator provides peace of mind during the uncertain months ahead. Prepare now and stay in control, no matter what the season brings.

We can evaluate your home or property and advise you on which type of generator / battery system would be best for you!
