Fremont’s housing spans early 1900s cottages near the Ship Canal, craftsman bungalows from the 1910s and 1920s, and a steady wave of ADUs and gut remodels layering new plumbing onto old bones. Nic’s Plumbing works the whole neighborhood, from the streets below the Aurora Bridge to the blocks past the Troll, and we plan every job around what’s actually in the wall, not what the block usually has.

What Fremont homes are dealing with, above and below ground
The blocks closest to the canal, around N 34th St and Fremont Ave N, hold some of the oldest housing in the neighborhood, simple cottages and foursquares built before or right around 1910. The same story shows up call after call: decent pressure downstairs, a weak trickle at the upstairs shower, rust-colored water in the first glass drawn after the house has sat overnight, classic signs of galvanized supply pipe closing up from the inside. Further out, toward Woodland Park and N 46th, craftsman bungalows from the 1910s and 1920s dominate, often with a mix of original galvanized and whatever a past owner swapped in during a partial remodel.
Fremont’s other defining feature is how much building happens on top of the old stock. Backyard ADUs and full gut remodels are common here, and each one means new fixtures tying into supply and drain lines that may be a century old. That’s usually when old galvanized pipe or a tired clay side sewer gets discovered mid-remodel.
Old-house note: Fremont is a combined-sewer neighborhood
The City of Seattle lists Fremont, along with Ballard, Wallingford and northern Queen Anne, as a combined-sewer area: stormwater and sewage share the same pipe on older streets before treatment at West Point. In a heavy storm that system can back up, and a basement floor drain is often the first place it shows.

How a visit works on your street
Narrow lots, alley access and street parking near N 36th St or Fremont Ave N are routine for us, not a surprise on the day. You get a live tracking link when the tech is on the way. Tech en route · live map Inside, canvas runners go down before anyone crosses original fir floors, and the tech traces what your house actually has, galvanized, a patchwork from an old remodel, or new PEX from an ADU build, before recommending anything. You get Good, Better and Best options in writing, and you approve one before a single cut is made — the number and the reasoning together, not a sales pitch on a tablet with a price that magically drops if you hesitate.

Questions Fremont homeowners ask
Is my Fremont home on a combined sewer?
Very likely on the older blocks. Seattle names Fremont, with Ballard, Wallingford and northern Queen Anne, as a combined-sewer area, where stormwater and sewage share a pipe before treatment at West Point. That system can surcharge in heavy rain, and a basement floor drain is often where it shows first.
We’re adding an ADU. Do you check the existing plumbing first?
Yes, and we’d recommend it. Tying a new unit into a century-old supply line without checking capacity first is how an ADU project turns into a mid-construction surprise. We can trace and camera the existing lines before your build starts.
Is the side sewer from my house to the street my responsibility?
Yes. In Seattle, the side sewer, the private pipe connecting your house to the public main, is the homeowner’s responsibility, not the city’s. Seattle keeps a public side sewer card viewer if you want to see what’s on file for your address.
Do I need a permit for sewer or drainage work in Fremont?
Most side sewer and drainage work needs a permit in Seattle, and work in the street right-of-way needs a separate SDOT permit. We handle the permitting as part of the job. If you’re not sure what a project needs, ask us and we’ll check before we quote.
