We warm up your day!™
Coeur d'Alene is the largest city in Kootenai County and where the most North Idaho new construction is happening — production builders north of I-90, custom homes on the lake, restaurant and retail buildouts in the downtown corridor, and lakefront remodels every season. We make the trip from Sandpoint because the work in CDA is worth doing right, and customers here tell us our installs are the same caliber as the corporate plumbing chains, at fair prices, with the family-owned crew that actually answers the phone. Licensed Idaho plumbers and water heater specialists across the full CDA spectrum.
Tankless retrofits in older lakefront homes. Hydronic boiler design for new custom builds. Whole-home water filtration for homes pulling lake or well water. Gas-line sizing for everything we install. Commercial water-heater service contracts for the restaurants on Sherman Avenue and the resorts on Lakeside. About one in five of our CDA jobs is a second-opinion call — generalists misdiagnose tankless and boiler systems, and we get asked to come fix what wasn't done right. New construction, remodel, emergency, contract — same crew, same number, same caliber of work.
When your water heater fails at 6am on a Tuesday, you don't want a generalist. You want the people who've installed 2,500+of them across Bonner and Kootenai counties. That's all we do — water heaters, tankless, boilers, hydronic radiant, filtration. We do it better than anyone in North Idaho.
Every other plumber in Sandpoint says “call for a quote.” We'll tell you up front where pricing starts. Your exact number lands in writing after a free in-home assessment — no surprises on install day.

Most Coeur d'Alenehomeowners call us when one of these shows up. Some are same-day emergencies; some can wait until tomorrow. We'll tell you which on the phone — and we'd rather you call once and not need us than wait too long and end up needing a major water-damage cleanup.
Cold showers, lukewarm tap. Could be a failed gas valve, blown heating element, or pilot issue. Same-day Coeur d'Alene water heater repair for emergencies — call us first.
Active leak — this is an emergency. Don't try to drain the tank yourself; old drain valves rarely reseal once cracked. Photograph the leak, call us, we bring the right parts on the first trip.
Sediment buildup at the tank floor. Reduces efficiency, shortens lifespan. Annual Coeur d'Alene water heater service (about 90 minutes on the truck) clears it before it kills your unit.
Anode rod is gone, tank lining is corroding. Weeks to failure, sometimes days. Replace proactively — emergency replacement after a tank fails plus water-damage cleanup costs 4–5× a planned swap.
Thermocouple, gas valve, or venting issue on a gas water heater. We diagnose on the truck — most Coeur d'Alene pilot-light fixes are same-visit.
Heating element failure (electric tanks), broken dip tube, or the tank's just sized wrong for your household. We can repair or recommend a tankless / larger tank that actually fits your usage.

“The water heater in our building failed; the tank had ruptured, was leaking into the pan, and had actually started to seep into the subfloor. What a mess and a headache!! I definitely didn't want to deal with this, and I was worried about getting taken for a ride. These guys were on it immediately, made sure we were f…”
“Tyson responded to an issue we were having with our radiant floor heater boiler. I was out of the country trying to coordinate over the phone, and immediately felt relief when Tyson responded to my message. I appreciate that he specializes in these kind of systems, but also is from a family that does standard plumbing.…”
“Tyson came out quickly, diagnosed the problem, and ordered the needed part which he identified as under warranty. When the part was delivered he installed it efficiently, made a few plumbing additions, performed some system maintenance, and we were up and running. This is a hydronic installation operated with Takagi ha…”
