Editorial Review
Our Take on Best Plumbing
The combination of a 1968 start date, a fixed north Seattle address and 4.6 stars from 815 Google reviews as of September 27, 2026 is about as solid a paper trail as this trade offers. The scope is wide enough that most household problems fall inside it, though a broad full-service shop with 24-hour cover is rarely the cheapest quote on a small job. Get the sewer or water line scope in writing and ask who handles the permit.
Best for: homeowners who want one company for both emergency repairs and sewer or repipe work
What We Like
- Trading since 1968 according to its own website, with a fixed showroom address on Aurora Ave N
- 4.6 stars from 815 reviews on its Google Business Profile, read September 27, 2026
- Published hours show 24 hours a day, seven days a week
- Covers both small fixture work and major sewer, water line and repipe projects
- Boiler and tankless water heater work suits older Seattle housing stock
- Financing offered through GreenSky, per the company website
Things to Consider
- A large full-service company with round-the-clock cover is rarely the cheapest option on a simple drain clear
- Advertised promotions and discounts come from the company's own site and should be confirmed when booking
- Licensing, bonding and insurance details are not stated in the brief, so verify them with Washington L&I before a large job

About Best Plumbing
Longevity is the first thing worth noting here. A shop that says it has been trading since 1968 has been through several generations of Seattle housing stock, from the pre-war bungalows in Ballard and Wallingford to the 1960s split levels further north, and that matters in a city where what sits under the lawn is often clay or cast iron laid a long time ago. Best Plumbing works out of 8820 Aurora Ave N, which puts crews within easy reach of Green Lake, Phinney Ridge, Greenwood, Fremont and Northgate, with the website describing a service area across the wider Puget Sound region.
The service list is broad rather than specialised. Water heaters sit near the front of it, including tankless and electric units, and the site also covers boilers, which is genuinely useful in a city with plenty of hydronic and steam heat still running in older homes. Beyond that the range takes in fixtures such as toilets, sinks, tubs and shower valves, gas line installation and repair for ranges, dryers and outdoor appliances, whole-home repipes and water piping repair, leak detection, shut-off valve work, water filtration, garbage disposals, and pumps of several kinds: sump, sewage ejector, booster and hot water recirculation. Underground, the company lists sewer camera inspection, spot repair, trenchless replacement and full sewer replacement, along with water service line repair and replacement and backflow prevention.
Sewers deserve their own paragraph in any Seattle profile. Homeowners here are responsible for the side sewer from the house to the public main, and that line frequently runs a long way, under driveways, hedges and the roots of big maples and cedars. Repeated backups are usually a symptom rather than the problem, and the sensible sequence is a camera inspection first, a locate second, then a conversation about whether a spot repair, a pipe burst or a full dig makes sense. Side sewer work in the city generally requires a permit and a registered side sewer contractor, so ask directly who pulls the permit, who arranges the restoration of concrete or asphalt, and what happens if the camera finds a second problem further downstream once digging starts.
Who does this suit. Households that would rather deal with one established company for both a Saturday night burst supply line and a planned sewer replacement in spring, and people who want financing available on a large job, which the site says is offered through GreenSky. It should also suit owners of older homes facing galvanised or polybutylene supply lines, since repipes, boilers and drain replacement all sit within the advertised scope. It is likely to be a weaker fit for someone hunting the lowest possible price on a simple drain snake, because a long-established full-service company with round-the-clock cover tends to price accordingly. Anyone wanting a sole trader who will be on every job personally will also want to look elsewhere; the website talks about a team of trained technicians and a showroom, which points to a larger operation.
On reputation, the Google Business Profile showed a 4.6 rating from 815 reviews when it was read on September 27, 2026. A figure that high across that many reviews suggests consistency over years rather than a recent push, though with any volume like that a reader will find some unhappy accounts mixed in, and it is worth skimming the one and two star ones for patterns around pricing or callbacks rather than reading only the summary number.
A few questions save trouble later. Ask whether the dispatch fee or after-hours call-out charge is separate from the repair price, and whether it is credited against the work. Ask for the estimate in writing with the scope described, not just a total. On a water heater, confirm whether expansion tank, pan, seismic strapping and venting changes are included, because current code requirements can turn a straight swap into a larger job. On excavation, ask about the warranty on the new pipe and on the backfill and surface restoration, and whether that warranty transfers if the house sells. Confirmation of current licensing and bonding through the Washington Department of Labor and Industries is straightforward to check by name and is worth doing before any large job.
Compared with the alternatives in this market, which range from one-van operators to national franchises with heavy advertising, the pitch for best plumbing here is scope plus a local address you can actually visit. Best Plumbing publishes 24-hour availability every day of the week, and for a burst line on a wet January night that single fact often decides the call.

Best Plumbing FAQs
Does Best Plumbing answer calls at night and on weekends?
Published hours show open 24 hours every day of the week, and the company promotes 24/7 emergency service on its website. For an overnight or holiday call it is worth asking on the phone what the after-hours call-out charge is and whether it is applied toward the repair.
How good are the reviews?
The Google Business Profile showed a 4.6 rating from 815 reviews when it was read on September 27, 2026. That is a large sample for a local plumbing company, so the average reflects years of work rather than a handful of recent jobs, and it is still worth reading a few of the lower-scored reviews for recurring themes.
Do they handle Seattle side sewer replacements?
Yes, the website lists sewer repair, trenchless sewer repair and full sewer replacement, along with sewer camera inspection. Side sewer work in Seattle normally needs a permit and a registered side sewer contractor, so confirm who pulls the permit and who is responsible for restoring driveways, walkways and landscaping afterwards.
Where are they based and how far do they travel?
The address is 8820 Aurora Ave N, Seattle, WA 98103, in the Green Lake and Greenwood area of north Seattle. The company's site refers to serving Puget Sound residents and has a service area page, so ask about your specific neighbourhood when you call, especially outside the city limits.
Can I finance a large job like a sewer or water line replacement?
The website says financing is available through GreenSky. Terms, approval and rates are set by the lender rather than the plumber, so get the payment details alongside the written scope of work before committing.
What should I ask before booking best plumbing work on an older Seattle home?
Ask about the pipe material you have and what the replacement plan is. Galvanised supply lines, cast iron drains and old clay side sewers all behave differently, and a repipe or drain replacement in a 1920s house often means opening walls or crawlspace access. Get the estimate in writing, confirm whether code items such as expansion tanks or seismic strapping are included on a water heater, and check the warranty on both the new pipe and any backfill or surface restoration.
Do they do gas appliance hookups?
Gas line installation and gas line repair are both listed on the company's site, which typically covers runs for ranges, dryers, fireplaces and outdoor grills. Gas work is permit and inspection territory in Seattle, so ask how that is handled as part of the quote.
Is Best Plumbing licensed and insured?
We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.
What areas does Best Plumbing serve?
Seattle. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Does Best Plumbing offer emergency service?
Emergency availability is not listed for this company. If you need an urgent call-out, check the ranking for companies that do list it.
What warranty do they offer?
Warranty terms are not on file. Ask for them in writing before work starts.
How was this profile built?
Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.
Can a business pay to improve its profile?
A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
