Mark Sewell has over 36 years of gutter design and installation expertise. During his junior year attending West Seattle’s Sealth High School, he began installing gutters for Bill Otekirk, owner of one of only two continuous gutter installation companies in Seattle at the time (Starburst Gutters).

Upon graduation, Mark took a year off to ride his bike and travel around the country before coming back home to West Seattle, getting married, and starting Level Line Gutters.

Mark takes pride in knowing that he has installed every foot of gutter himself since the beginning, using nothing but the best materials and personal care in craftsmanship. His work has literally become part of West Seattle history, with gutters installed on homes from Alki Point and the North Admiral district, to the Alaska Junction, Gatewood, Fauntleroy and Arbor Heights.
