Life in Post Falls offers the best of North Idaho living — open skies, growing neighborhoods, and cold winters that can put your home’s plumbing to the test. Many homes here were built in the 1990s and early 2000s, translating to aging water lines, older water heaters, and outdated fixtures becoming increasingly common. Combine that with winter lows that dip into the 20s and the area’s mineral-rich water, and it’s easy to see why Post Falls homeowners rely on experienced plumbers who know local conditions inside and out.
At Mainstream, our licensed plumbers specialize in keeping Post Falls homes and small businesses running smoothly year-round. We handle everything from frozen or leaking pipes to tankless water heater installs, drain clogs, fixture upgrades, and full plumbing remodels. Our team also helps protect your plumbing long-term with professional water softener installation — an essential defense against the hard water common throughout Kootenai County. Whether you live in Prairie Falls, near the river, or run a small shop off Seltice Way, you can count on fast, honest service backed by 20+ years of experience in the Inland Northwest.
