Reviews from Preston customers

★★★★★

“Whole house rewire on a 1920s home with knob and tube. They were careful with the plaster walls and kept power on in the rooms we were living in. Our insurance company was happy too.”

Dan and Kelly R., Preston, WA
★★★★★

“Upgraded from 100 to 200 amps before adding a heat pump. The utility coordination was seamless and the new panel is beautifully labeled.”

Rob H., Preston, WA
★★★★★

“Called at 9pm with a burning smell from an outlet. Someone answered right away and a technician was here within two hours. Turned out to be a melted backstab connection. So glad we did not wait until morning.”

Angela M., Preston, WA

Generator Installation in Preston – frequently asked questions

What size generator does a Preston home need?

Most homes are well served by a 14 to 26 kW standby unit, but the right size depends on your furnace or heat pump, well pump, and appliances. We run a load calculation before recommending a size.

How does an automatic transfer switch work?

When utility power fails, the transfer switch senses the outage, starts the generator and moves your home onto generator power in seconds. When the grid returns, it switches back and shuts the generator down.

Can you install a plug for my portable generator?

Yes. A manual transfer switch or interlock kit with an exterior inlet lets you power essential circuits safely without running extension cords through windows.

How long does installation take?

Most standby installs in Preston are completed in one to two days once the pad, gas line and permit are in place.
