Call (425) 429-8911

The short version

We are plumbers and heating techs in Seattle who answer the phone, show up when we say we will, and charge what we quoted. No upsell, no mystery fees — just the work done right, the first time. That's the whole business plan.

Services

01

Water Heater Installation & Repair

Tank or tankless — we size it right for your house, haul the old one away, and leave you with hot water the same visit.

02

Tankless Water Heater Upgrades

Swap a bulky tank for endless hot water. We handle gas line sizing, venting, and permits so the upgrade is one clean job.

03

Combination Boilers

One unit for heat and hot water. A good fit for Seattle homes short on mechanical-room space.

04

Furnace Installation, Repair & Maintenance

New installs, mid-winter breakdowns, and tune-ups that keep a furnace running through the cold snaps.

05

Radiant Heating Systems

Floor heat that warms the room instead of the ceiling — installs and replacements for hydronic systems.

06

Sewer Repair & Replacement

Trenchless pipe bursting and pipe lining where it fits, so most jobs need minimal digging. Same-day sewer inspections.

07

Leak Detection & Pipe Repair

Pinpoint the leak before we open anything up. Spot repairs that fix the break without tearing the house apart.

08

Gas Line Services

New gas lines, reroutes, and safety checks — pressure-tested and permitted.

09

Water Service Lines

Repair and replacement of the line from the street to your house.

10

Fixture Installation

Faucets, toilets, and shower valves installed straight, sealed, and tested before we leave.

11

Bathroom & Kitchen Plumbing

Rough-ins, remodels, and full fixture packages for kitchen and bath projects.

12

Drain Cleaning

Slow drains cleared properly — and we'll tell you if the clog is a symptom of a bigger sewer problem.

Common questions

Do you offer trenchless sewer repair?

Yes. We do pipe bursting and pipe lining wherever the line allows it, which means most sewer jobs need minimal digging. We start with a same-day camera inspection to see what your line actually needs.

What are the signs of a broken sewer line?

Backups, foul odors, slow drains all over the house, wet patches in the yard, or gurgling sounds from toilets and drains. Any of those means the line deserves a camera inspection soon.

Do you handle city permits?

Yes. We take care of city permits and the required inspections for sewer, gas, and water heater work — you don't have to chase paperwork.

How much does a water heater replacement cost?

Every house is different — gas vs. electric, tank vs. tankless, venting, and access all change the number. We price each job after looking at it, upfront and in writing. (Sample figures on this page are examples only.)

Are you licensed and insured?

Yes — licensed, bonded, and insured in Washington. You'll get one written price before work starts, and the crew that shows up is the crew we send.
