Learn moreWhy Treasure Valley homeowners call Clearwater
Nate Ellison earned his Idaho master plumber license working on the older homes of the North End and the Bench, where galvanized supply lines, cast-iron stacks and clay sewer laterals are still common. He started Clearwater in 2011 with one van and a simple promise: tell people the truth about their plumbing, charge a fair flat rate, and clean up before leaving.
The company has grown with the valley. Today our crews work from the historic neighborhoods of Boise to the new subdivisions of Meridian, Eagle and Nampa, and we still answer our own phone. Our license is on file with the Idaho Division of Occupational and Professional Licenses, we pull permits when the code requires one, and we stand behind every repair in writing.

The price is the price
We quote the job, not the hour. You see the number before we start, and it doesn't change because something took longer than we expected.
Diagnose first, sell second
A water heater that won't light might need a $90 part, not a new unit. We check before we recommend, and we show you what we found.
Plumbers you'll see again
Our technicians are employees, not subcontractors. Many customers ask for the same tech by name, and we do our best to send them.
Built for this water
Treasure Valley water is some of the hardest in the Northwest. Everything we install is chosen and set up with mineral scale in mind, so it lasts.
How a service call works
- 1
Call or book online
Jess in the office finds the first opening that fits your schedule, usually same or next day, and texts you when your plumber is on the way.
- 2
Diagnosis and flat quote
The plumber finds the actual problem, explains your options and gives you a written price for each. No work starts until you say so.
- 3
The repair
Our vans carry the parts for most common repairs, so the fix usually happens on the first visit. We put down floor protection and clean up after.
- 4
Walk-through and warranty
You see the finished work, get the camera footage or photos, and leave with a written warranty on parts and labor.
What our customers say
Our 1930s North End house had roots in the clay sewer line every spring. Nate ran the camera, showed us the breaks on his tablet, and the crew replaced the lateral in two days without touching the big maple out front. No more backups.
Heater died on a Sunday night. Carlos was there Monday morning with a new unit on the van, had it installed by noon and hauled the old one away. The quote he gave on the phone was the price we paid.
We'd replaced two dishwashers in eight years before anyone explained what Nampa water was doing to them. Clearwater sized a softener for our family of five and the difference in the shower glass alone was obvious in a week.
