Local knowledge

We're local to Deephaven — actually local

We're a family plumbing company, and Deephaven is a city we work regularly — the lakefront and near-lake homes along St. Louis Bay, Carsons Bay, and Robinsons Bay, the wooded lots off Vine Hill and Minnetonka Boulevard, and the older cottage-era streets near Chowen's Corner.

Deephaven is different from its neighbors in one big way: most of the city has no municipal water. That makes well pumps, pressure tanks, and water treatment everyday work here — and it makes the water in every house a question only a test can answer.

What Deephaven throws at its plumbing

You are the water utility

Outside two small pockets served by Shorewood and Minnetonka, Deephaven runs on private wells drilled into the Prairie du Chien–Jordan aquifer. That means no annual water report, no utility monitoring, and water that commonly tests 14 to 30 grains per gallon — very hard — with iron, iron bacteria, manganese, and sometimes arsenic and radium, all documented in this aquifer regionally. The Minnesota Department of Health recommends testing bacteria every year, nitrate every other year, and arsenic, lead, and manganese at least once. Our free in-home test covers hardness, iron, pH, chlorine, and dissolved solids on the spot, and we'll tell you what to send to a certified lab.

Pumps, tanks, and the plumbing of lake homes

A well system is a machine — pump, pressure tank, pressure switch, check valve — and when it fails, the house has no water at all. We repair and replace all of it. The homes themselves range from winterized cottages with galvanized lines and crawlspace plumbing to custom rebuilds with modern systems fed by a fifty-year-old well; either way, the water heater is fighting very hard water every day and lasts years longer behind a properly sized softener and iron filter.

Slopes, shoreline, and a lake at the bottom of every yard

Deephaven's lots slope toward the bays, and water runs downhill toward basements that were rarely built for a finished lower level. Sump pumps here handle both spring melt and a lake-level water table, and a frozen discharge line in a January thaw is a burned-out motor. On the drain side, older homes are on septic systems or long private laterals under mature oaks — roots and settling are the usual culprits when a drain slows, and a camera finds which.

Good to know

Deephaven questions, answered straight

Do you offer same-day service in Deephaven?

Yes — same-day service is the standard in Deephaven, 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 Deephaven?

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

We just bought in Deephaven and we're on a well. Where do we start?

With a test. Our free in-home test gives you hardness, iron, pH, and dissolved solids in twenty minutes; then we'll tell you what to send to a certified lab — arsenic and bacteria at minimum in this aquifer. From real numbers we size treatment that fits, and we'll say plainly if the well is already fine.

How fast can you respond to a plumbing emergency in Deephaven?

Call us and we'll give you an honest arrival time. For a burst pipe, shut off the main water valve first (usually in the basement near the meter), then call. We offer same-day and emergency service.

Do you repair well pumps and pressure tanks?

Yes — pumps, tanks, switches, and check valves. No water at all is an emergency for a household, and we treat it like one.

Is arsenic really a concern here?

Roughly one in ten private wells in Minnesota has elevated arsenic, and the aquifer under Deephaven is one where it's documented. It has no taste or smell, and only a certified lab test finds it. If it's there, treatment at the kitchen sink handles it.

Do you charge extra to come to Deephaven?

No. No travel surcharge, no service-call games — Deephaven is squarely inside our service area. You get a free estimate and a flat-rate price before any work starts, same as every city we serve.
