Our Philosophy

Why we're specialists, not generalists.

The plumbing industry has two tiers: generalists who do every kind of plumbing work indifferently, and specialists who go deep on a narrow band of the trade and execute it at a level the generalists cannot match. We chose the second path in 2005 and have not looked back. Tyler is an Idaho-licensed master plumber with 20+ years of plumbing and gas-fitting experience; the company is fully bonded and insured. Our license, code knowledge, and standards are identical to any general plumbing contractor — we have just chosen to point them at the work where depth pays off most.

The work where depth pays off most is the work most homeowners and builders get burned on by generalists: water heater installation (where 30% of failed units we get called to fix had at least one of: undersized gas line, missing expansion tank, wrong venting, or no permit), hydronic and radiant floor systems (where the failure modes are unfamiliar to anyone who learned on forced-air heat), water filtration (where the wrong equipment recommendation wastes thousands of dollars solving the wrong problem), new construction rough-in (where the schedule discipline and code documentation determine whether the project closes on time), and commercial water-heating (where uptime literally costs money every minute).

When you call us, you get a licensed plumber who has done your specific install over a thousand times. You get a written quote before any work starts, the same crew on every visit, and an owner on the phone — Tyler or Tyssen Case, not a dispatcher. We do not do drain cleaning, fixture work, repipes, sewer lines, septic, HVAC, or electrical. If you need any of those, we are happy to refer you to a generalist we trust. For everything below, we are the right call.

01 · Water Heaters

Tank · Tankless · Hybrid Heat-Pump.

Water heating is the company namesake — what Tyler started with one truck in 2005 and what we have installed over 2,500 of since. We work in three main categories. Tank water heaters (gas, electric, propane) are the reliable workhorse — 30 to 75 gallons of stored hot water, 10–15 year lifespan with annual maintenance. Bradford White is our default brand for tanks because their dealer-only distribution model means installer-level quality control.

Tankless water heaters (Navien NPE-A2, Rinnai RX) heat water on demand through a heat exchanger — endless hot water, 95%+ efficiency on condensing units, 20+ year lifespan with annual descaling. Tankless conversion is a real install: gas line resizing, new venting, condensate drain, mounting. We do gas line sizing as part of the quote, not as an upcharge after we open the wall.

Hybrid heat-pump water heaters (Rheem ProTerra, A.O. Smith Voltex) are 2–4× more efficient than standard electric resistance — they pull heat from ambient air using a small refrigeration cycle. Best fit: homes on electric (no gas service), households with high hot-water bills, and an unconditioned basement or garage to install in. Federal Inflation Reduction Act tax credits and Idaho utility rebates frequently offset a meaningful share of install cost — we help document both.

02 · Boilers & Hydronic

Radiant floor heat · snow-melt · indirect tanks.

Boilers and hydronic heating are the second-largest piece of what we do — and the place we most commonly get called as the second opinion. About one in five of our boiler calls is a customer who already paid someone else and is still cold. We carry common Triangle Tube, Lochinvar, Weil-McLain, and Burnham parts on the truck for first-trip repair, and we design and install full hydronic systems from blueprint through commissioning.

Modern mod-con condensing boilers (Triangle Tube Prestige, Lochinvar Knight, Weil-McLain Evergreen) are the residential default — 92–96% AFUE, modulating fire rate, PVC venting, 15–20 year lifespan with annual service. We size on actual heat-loss calculation per room, not on square-footage rules of thumb. Oversized boilers short-cycle and die young.

Radiant floor heating is the most comfortable heat available — even temperatures floor to ceiling, no drafts, no dust circulation. Three install methods: in-slab (for new construction, PEX tied to rebar before pour), staple-up retrofit (under existing subfloor, with reflective insulation), and above-grade overlay panels like Warmboard. Pairs perfectly with mod-con boilers because radiant runs at 95–115°F where condensing boilers are most efficient. We also design and install snow-melt slabs for driveways and walkways, indirect-fired water heaters that use your boiler to make domestic hot water, and full annual service with combustion analysis on every visit.

03 · Water Filtration & Treatment

Lab-tested. Then solved.

Water filtration is the most over-sold and under-engineered category in our industry. Door-to-door salespeople test your water with a single hardness strip and quote an expensive system that solves a problem you may not have. We do it differently. We pull a comprehensive lab-grade water test that measures hardness, iron, manganese, sulfur, pH, total dissolved solids, nitrates, sulfates, tannins, and bacteria — and only then recommend equipment, sized to your actual numbers.

About half the homes we serve are on private wells. Bonner County wells frequently come back with hardness (10–25 grains per gallon is common), iron staining (above 0.3 ppm causes orange laundry), manganese (causes black staining and metallic taste), hydrogen sulfide (rotten-egg smell), and seasonal bacterial counts. Each has a different fix. A water softener does not solve any of them except hardness.

Our toolkit covers the full range: demand-initiated softeners for hardness, air-injection oxidizing filters for iron and manganese, chlorine-injection or oxidizing systems for sulfur, UV purification for bacteria, reverse osmosis at the kitchen tap for nitrates and drinking-water polish, and specialty media for tannins and other organics. We test before we sell, we size to your numbers, and we re-test 30 days after install to confirm the system is doing what we promised.

04 · New Construction

Builder rough-in · hydronic design · spec packages.

New construction is a healthy share of our schedule — production builders putting up tract homes, custom builders working on lakefront or hillside view properties, and general contractors managing remodels that count as new construction by scope. We do whole-home water-side rough-in, hydronic system design from blueprint to commissioning, gas and venting layouts that pass first inspection, and builder pricing for spec packages where the same configuration repeats across a development.

What makes us a fit for builders is schedule discipline. Permits pulled when they need to be pulled, rough-in plumbing on the schedule the framers are expecting, finish plumbing aligned with the cabinet and tile installers, inspection sign-offs documented for closing. We run the same Manual J-style heat loss calculations for every hydronic system, size every gas line for full diversified BTU demand, and coordinate directly with architects, mechanical engineers, and interior designers when their decisions touch the water-side scope.

Custom and lake-house projects are some of our favorite work — they usually involve hydronic radiant heat in multiple zones, a snow-melt slab, an indirect tank for domestic hot water, a recirculation pump for instant hot at the far fixtures, whole-home filtration with UV and softener, and a primary boiler all in one project. We design the integration as a single system, not as separate sub-systems handed off in pieces.

05 · Residential & Commercial

Restaurants · lodging · multi-family · service contracts.

Half our calendar is residential, half is commercial. Restaurants on Sherman Avenue and Cedar Street, lodging accounts at Schweitzer and Hope Bay, multi-family in Coeur d'Alene and Hayden, property management firms managing 30-property residential portfolios, and the small-commercial side that nobody else wants — the one-coffee-shop and one-laundromat accounts that need a real plumber on speed-dial. We work all of it.

Commercial water-heating is its own discipline. Higher recovery rates, ASME-stamped tanks for some applications, mixing valves and master tempering at the right code-required temperature (140°F+ at restaurant dishwashers), recirculation systems that have to work at 3am when staff arrive, and service contracts because downtime costs more than maintenance. We size for peak simultaneous demand, document combustion analysis at startup, and provide the inspection-ready paperwork the kitchen manager or property manager needs.

Service contracts are how the smartest commercial accounts manage water-heater risk — twice-yearly visits with combustion analysis, sediment flush, descale, anode inspection, written log, and priority emergency dispatch ahead of the new-call queue. Per-unit-per-year pricing locked for the contract term. Most restaurants and lodging properties on contract make the contract pay for itself in the first major repair call.

How we quote

Written quotes, no surprises.

We do not post fixed prices on the site because every job is different — fuel type, venting, gas line condition, well chemistry, square footage, existing infrastructure, and the unit selected all change the number. A “from $X” price tag sets a false floor that almost never reflects what you actually pay. We would rather take a few minutes on the phone or in person to give you a real number than mislead you with a teaser.

What we promise instead: a free written quote on installs and most replacements, every line item spelled out, every option laid alongside its alternatives, and the price you see on the page is the price on the invoice. Planned consultations and emergency diagnostics carry a small fee that is disclosed before dispatch and credited toward the work if you proceed. Hidden issues uncovered mid-job are absorbed by us, not added to your bill.

If a competing quote comes in materially cheaper, ask what they are skipping. The typical answers we hear: no permit, no expansion tank, no sediment trap, no warranty registration, builder-grade unit instead of the dealer-only model. We do not skip those things — they are the reason our installs hold up for fifteen-plus years.

Plumbing services — FAQ

Are you a real licensed plumber, or just a water heater installer?+
Real licensed plumber. Tyler Case is a licensed Idaho master plumber with 20+ years of plumbing and gas-fitting experience; the company is fully bonded and insured. We focus our practice on water-heating, hydronic, and water-treatment plumbing — but the licensing, code knowledge, and standards are the same as any general plumber. We can ship a certificate of insurance to your homeowner's insurance the same day.
Why do you specialize? Why not do general plumbing?+
Because depth beats breadth on the work we do. We have installed over 2,500 water heaters since 2005, designed and commissioned hundreds of hydronic systems, and lab-tested wells across every corner of Bonner, Kootenai, and Boundary County. That repetition is why our diagnostics are faster, our installs callback less, and our warranty work is rare. A generalist who does drains on Monday and water heaters on Tuesday cannot match it.
What plumbing work do you NOT do?+
We do not do drain cleaning, sewer line work, septic systems, general fixture work (faucets, toilets, repipes), HVAC, or electrical. If you need a clogged drain cleared or a leaky faucet replaced, you want a generalist plumber — not us. We are happy to refer.
Do you do all five of your services in every city you serve?+
Yes. Water heaters, boilers and hydronic, water filtration, new construction, and residential/commercial — all available across our service area. Bonner County (Sandpoint, Ponderay, Sagle, Dover, Kootenai, Hope, Priest River, Clark Fork, Laclede, East Hope, Cocolalla) and Kootenai/Boundary counties (CDA, Hayden, Post Falls, Rathdrum, Bonners Ferry, Spirit Lake, Athol).
How fast can you respond to an emergency?+
Same-day for most no-hot-water emergencies during business hours (M–F 8am–7pm). Bonner County typically within 2 hours; Kootenai and Boundary typically within 2–4 hours. After-hours emergency line is live for no-hot-water calls — Tyler or Tyssen actually picks up.
Do you do free estimates?+
Yes for installs and most replacements. Planned on-site consultations and emergency diagnostics carry a small fee that is disclosed before dispatch and credited toward the work if you proceed. Final price is in writing before any work starts. Hidden issues uncovered mid-job are absorbed by us, not added to your bill.
Do you carry parts on the truck?+
Yes. We stock common Bradford White, Rheem, A.O. Smith, Navien, and Rinnai water-heater parts; Triangle Tube, Lochinvar, Weil-McLain, and Burnham boiler parts; Taco and Grundfos circulators; Fleck softener controllers; common Pentek/Watts cartridge filter housings. About 85% of our service calls finish first-trip.
Do you provide written warranty?+
Yes. Written labor warranty on every install (1 year standard, longer on tankless and heat-pump installs). Manufacturer parts warranties registered for you at install — typically 6–12 years on tanks, 12–15 years on tankless heat exchangers, lifetime on Triangle Tube heat exchangers. All transfer to the next homeowner if you sell.
Are you Google Guaranteed and BBB accredited?+
Yes — Google Guaranteed (Local Service Ads approved) and BBB A+ accredited. 5-star average across 45+ verified Google reviews from Sandpoint, CDA, Hayden, Post Falls, Sagle, and the rest of our service area.
Do you do commercial work and service contracts?+
Yes. Restaurants, retail, multi-family, lodging, property management — see the Residential & Commercial page for the full scope. Annual or twice-yearly service contracts available with priority emergency dispatch for active customers.
Will you work with my builder, architect, or property manager?+
Yes. New construction is one of our five core service categories. We do plan review, hydronic system design, builder pricing for spec packages, and full closeout documentation for resale disclosure. Property management portfolios are billed quarterly with consolidated invoicing.
What does a tankless conversion typically cost?+
Tankless conversions vary widely based on your existing gas line size, venting path, the unit selected, and whether you are converting fuel types. We give you a free written quote that lays out the full scope before any work starts — no surprise add-ons mid-install.
Do you handle water filtration if I am on city water?+
Yes. City water customers (Sandpoint, CDA, Hayden, Post Falls, etc.) typically deal with chlorine taste/smell, occasional sediment, and moderate hardness. We test before we install on city water just like we do for wells, and the equipment selection is different — usually a whole-house carbon filter plus a softener rather than the well-water iron-and-sulfur stack.
What is the difference between a water softener and a water filter?+
A water softener removes hardness (calcium and magnesium) by ion exchange. A water filter is a category that includes sediment filters, carbon filters, iron and manganese oxidizing filters, UV purifiers, and reverse osmosis. They solve different problems. We pull a comprehensive lab water test before recommending either, because the right answer depends on what is actually in your water.
Do you do radiant floor heating?+
Yes — radiant floor heating is a core part of our hydronic specialty. New construction in-slab radiant (PEX tied to rebar before pour), retrofit staple-up under existing subfloors (insulation and PEX from below), and above-grade overlay panels (Warmboard) for finished spaces. We design, install, pressure-test, commission, and warranty every system.
