Northwest Plumbing Services is a family-owned plumbing company serving St. Helens and the surrounding Columbia County, Oregon community. David and Mindy Sass established the business in 1991, and the team continues to help homeowners, property owners, builders, and commercial customers plan practical plumbing work. From a leaking faucet or clogged fixture to water and drain lines, repiping, water heaters, remodels, and new construction, we can talk through what your property needs.
