Boat repair around Sammamish.
East-shore private docks
Homes along the east shore of Lake Sammamish keep boats at their own docks. We service them where they sit, from routine maintenance to repairs.
Wake and ski boats
Lake Sammamish sees heavy summer use from wake and ski boats. Impellers, belts, ignition and cooling get a workout, and regular service keeps them reliable through the season.
Seasonal service
Spring commissioning gets the boat ready; fall winterization, a flat $150 for any boat, protects it through the cold months.
