Spokane homeowners know that plumbing problems rarely wait for a convenient moment. From the historic homes on the South Hill with aging pipes to the newer builds in Spokane Valley, every property faces unique plumbing challenges. Cold winters can freeze and crack water lines, while heavy use in multi-family housing or commercial spaces often leads to unexpected leaks and clogged drains. Reliable plumbing isn’t just a convenience here — it’s essential for keeping Spokane homes and businesses running smoothly year-round.
That’s where Mainstream comes in. Our licensed Spokane plumbers have decades of experience working with everything from vintage cast-iron pipes to modern PEX systems. We understand how the local climate and infrastructure affect your plumbing, and we know the headaches that come with low water pressure, slow drains, or a water heater on its last leg. More than just repairs, we provide solutions that last — so you can spend less time worrying about plumbing problems and more time enjoying everything Spokane has to offer.
