Local knowledge

We're local to Stillwater — actually local

Not a national franchise, not a call center routing you to whoever's available. We're a family plumbing company, and Stillwater is a city we work all the time — the Victorians on the hill above Main Street, the mid-century blocks of Croixwood, and the newer neighborhoods out toward Liberty on the Lake.

A river town built in the 1800s keeps a plumber humble. The houses here have outlived every pipe material ever put into them, the hill writes its own rules for drainage, and the St. Croix makes spring an event. We like it that way.

What Stillwater throws at its plumbing

The oldest houses in the metro

Stillwater was building homes before Minnesota was a state, and plenty of them are still standing proud on the hill. Open a basement ceiling in one and you'll often find every plumbing era at once — original galvanized, mid-century copper, 1990s plastic, all spliced together by a century of well-meaning hands. That layered plumbing fails in ways newer suburbs never see: fading pressure through corroded galvanized, drains that were re-sloped by settling long ago, and shutoff valves nobody has dared touch since the Nixon administration.

Hard water, with a PFAS asterisk

Stillwater pumps from eight city wells at about 13 grains per gallon — gentler than the west metro's worst, but still more than double what counts as "hard," so softeners remain standard equipment here. The bigger local story is PFAS: the city shut down one well after elevated detections and monitors the rest, and Washington County sits at the center of Minnesota's PFAS history. For drinking-water certainty at your own tap, under-sink reverse osmosis is the honest, economical answer — no fear-mongering required.

A hill, a river, and a real spring

Stillwater drains downhill toward the St. Croix, and every spring the snowpack tests that arrangement. Older stone foundations take on water, sump pumps earn their keep for weeks straight, and clay sewer laterals under the old street trees invite roots in through every joint. Meanwhile, supply lines in hundred-year-old exterior walls meet January with very little insulation between them and the weather. It's a beautiful town that keeps a plumber busy.

“Our water heater died on a Sunday and they had a new one in Monday morning. The price he quoted on the phone walkthrough was the price on the invoice.”

— Angela M.

“Finally a plumber who didn't try to sell us a whole system. He fixed the valve, showed us what to watch for, and left the utility room cleaner than he found it.”

— Kevin T.

Good to know

Stillwater questions, answered straight

Do you offer same-day service in Stillwater?

Yes — same-day service is the standard in Stillwater, not the exception. Call and we'll give you an honest arrival window, not a four-hour guess that becomes eight.

Are you licensed to work in Stillwater?

Yes. We hold Minnesota Master Plumber license PM652496, we're insured, and when a job needs a permit we pull it through the City of Stillwater and meet the inspector ourselves. Permit costs are part of the flat-rate price you approve up front.

Our house is a hundred-plus years old. Can you work on it without wrecking it?

That's exactly the kind of work we like. Stillwater's Victorians deserve a plumber who respects old plaster, original woodwork, and the reality that the shutoff diagram lives in nobody's head anymore. We open as little as possible, we tell you what we find, and we don't treat 'old' as a reason to sell you a gut job.

Should I be worried about PFAS in Stillwater's water?

Worth understanding, not panicking over. Stillwater shut down one of its wells after PFAS was detected above health guidelines, and the city monitors and manages the rest — Washington County sits at the center of Minnesota's PFAS story. If you want certainty at the drinking tap regardless of what any single test says, an under-sink reverse osmosis system is the straightforward, economical answer, and we'll give you the honest version of that conversation.

Why does my sewer line keep backing up?

In Stillwater's older neighborhoods it's usually tree roots working into clay sewer laterals that predate your grandparents — and on the hillside, pipes that have settled out of slope over a century. A camera inspection shows the actual cause, you see the footage too, and then you can weigh scheduled clearing against a permanent fix with real numbers.

Do you charge extra to come to Stillwater?

No. No travel surcharge, no service-call games — Stillwater is home turf for us. You get a free estimate and a flat-rate price before any work starts, same as every city we serve.
