We warm up your day!™
Hope hugs the east end of Lake Pend Oreille, where the highway carves between the water and the mountains and most of the homes are either lakefront cabins, second homes, or year-round residences with a view nobody in Sandpoint can match. Hope has its own rhythm — we winterize in October and recommission in May, then handle the in-season work that the seasonal-resident community needs. We're licensed Idaho plumbers who'll make the drive from Sandpoint without flinching, because Hope homes deserve the same caliber of work as a CDA new build.
A lot of Hope properties are running on water heaters that have been quietly limping along for too many seasons — and the worst time to find out a tank failed is when an owner pulls up in May after the cabin's been closed since October. We do proactive replacements, tankless conversions on properties that should have switched a decade ago, full freeze-prevention plumbing work, hydronic boiler service for radiant-floor cabins, and water filtration where the lake-side wells need help. Year-round Hope crew, year-round response.
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.

Annual service, no-heat diagnostics, full hydronic system design and install. Combustion analysis on every visit. Taco and Grundfos certified.

Most Hopehomeowners 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 Hope 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 Hope 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 Hope 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…”
“I had a fantastic experience with Water Heaters Unlimited! Tyler, the owner, was incredibly knowledgeable. His passion for customer service is evident.
