Justin Kan, the guy who helped make live streaming on the Web a real-world phenomenon has a new gig. But this one isn’t quite as sexy as broadcasting one’s life.

It is, however, a bit more practical: Helping home owners find house cleaners.

The Justin.tv founder’s new Exec online house cleaning service is expanding to the Seattle area today, offering residents in the Bellevue, Kirkland and Seattle areas  the chance to find high-quality house cleaners. It follows the company’s expansion in San Diego last week.

Exec’s arrival in Seattle marks the company’s first expansion in the Northwest, and it is a bit of a homecoming for Kan who hails from the Capitol Hill neighborhood and attended University Prep high school in Seattle. His other co-founders, including Amir Ghazvinian and brother Dan Kan, also hail from Seattle.

In fact, the Kan brothers used their parents’ home in Capitol Hill as a test location for the Exec service.

Seattle must be a dirty place because Exec marks the second online house cleaning marketplace to arrive here in the past 30 days. As readers of GeekWire may recall, last month we covered the arrival of Pathjoy, which charges $20 per hour for its cleaners.

Kan was familiar with Pathjoy, but said there are differences between the two ideas.

“We quote you a fixed rate immediately based on the size of your place, and stick to that regardless of how long it takes to clean your house to our standard,” Kan tells GeekWire. “We realized that our customers prefer to know up front how much something costs.”

Exec, which raised $3.4 million from angel investors last year, also sends cleaning teams of two so that homes get cleaned faster. They also don’t charge extra for supplies.

Kan said that a typically house clean on Exec costs about $100. When I put details in for my 3-bedroom, 2-bathroom home — and yes they did ask if I have a pet (which I do) — the cost was $177. (Interestingly, during the process users have the choice to either be home to let the cleaning crew in, or hide a key).

Exec grew out of the company’s online errand service, which is similar to TaskRabbit. That part of the business is not yet expanding to Seattle, but Kan said he hopes to add that here too eventually.

In addition to the expansion in Seattle, Exec is unveiling a dedicated iPhone app for the cleaning service.

“Our goal is eventually to make a suite of apps that solve all your real world needs,” says Kan.
