When a leak, worn fixture, slow drain, or water-line concern interrupts life at home or work, Northwest Plumbing Services can help you sort out the next step. Family-owned by David and Mindy Sass and established in 1991, our St. Helens team provides practical plumbing service for homeowners, remodels, new construction, and commercial spaces. From pipes, faucets, toilets, and garbage disposals to repiping and water heaters, we focus on understanding the problem, explaining workable options, and completing the right repair or installation for the building.
Plumbing repairs and replacements
Call us about plumbing repairs involving water or drain lines, leaks, damaged pipes, faucets, toilets, and disposals. If a repair is no longer the sensible option, we can discuss replacement or repiping based on the condition of the system and your plans for the property. A small drip or recurring clog is worth addressing before it damages cabinets, flooring, or finished walls.

Water heaters and everyday comfort
Northwest Plumbing Services works with tank and tankless water heaters. If hot water runs out quickly, temperatures fluctuate, or the unit is leaking, turn off the water supply when safe and contact the office for guidance. We can help you compare repair or replacement considerations for your household or facility.
Remodel, new construction, and commercial plumbing
Planning a kitchen or bathroom remodel? Plumbing decisions are easiest to manage before walls and finishes are closed. We also provide plumbing for new construction and commercial projects. Share the scope, drawings, access details, and timing with our office so the team can advise on the appropriate next step.
