An April 14 two-alarm fire at a commercial building in Factoria resulted in an estimated $500,000 in damage to the building’s tenant, Bright Now! Dental.

According to Jody Martin, a spokesperson for Bright Now, no one was inside the building at the time the fire started. The office’s interior space was destroyed and the exterior structure of the building is currently unsafe to enter, Martin said.

Fire crews from Bellevue, Mercer Island, Kirkland, and Eastside Fire and Rescue were able to bring the fire under control within about an hour of their arrival.

Due to the extensive damage, the Bright Now! Dental offices will remained closed for approximately six to nine months. Patients of the Factoria location are being redirected to the company’s offices in Issaquah and Bellevue.

As of this time, the cause of the fire is unknown.
