Editorial Review
Our Take on Gene Johnson Plumbing
The scale here cuts both ways. Nearly 4,800 Google reviews at 4.8 stars is a lot of consistency to argue with, and a company running plumbing, drain, HVAC and electrical crews on 24-hour dispatch is genuinely useful when an old North Seattle house throws two problems at once. Just go in expecting a menu-priced, options-based sales conversation rather than an hourly handshake, and ask which of the advertised discounts actually applies to your job.
Best for: homeowners in older Seattle houses who want plumbing, sewer, HVAC and electrical handled by one company
What We Like
- 4.8 stars from 4,797 reviews on its Google Business Profile as of 26 September 2026
- Published hours are 24 hours a day, seven days a week, suited to burst pipes and mainline backups

- Trading since 1976 per its own website, with a long record in North Seattle
- Full sewer capability including camera scoping, hydrojetting and trenchless replacement
- Advertises free estimates and free second opinions on major repairs or replacements
Things to Consider
- A large multi-van operation, so you may not meet the same technician twice

- Two different phone numbers appear publicly, so confirm which one reaches dispatch
- No pricing for standard service calls or after-hours work is published

About Gene Johnson Plumbing
Few plumbing outfits in Seattle have been trading as long as this one. The company dates itself to 1976 and now operates out of 10011 Greenwood Ave N, working across plumbing, drain and sewer, heating, cooling and electrical. That breadth is the defining thing about gene johnson plumbing: a single dispatch that can send a plumber for a slab leak on Monday and an electrician for a panel upgrade later in the week, rather than leaving a homeowner to coordinate three separate trades.
On the plumbing side, the published service list is wide. Leak detection and slab leak repair, water line installation and replacement, whole-house repiping, burst pipe repair, water heaters including tankless, sump pumps, water softeners and filtration, gas line repair and installation, and the everyday fixture work of toilets, faucets, sinks, showers and garbage disposals. Drain and sewer is treated as its own department, covering drain cleaning, camera scoping, hydrojetting, sewer line repairs, trenchless sewer repair and replacement, city sewer hookups, French drains and wet yards. Heating and cooling runs to furnaces, boilers, heat pumps, ductless mini-splits, radiant systems and indoor air quality equipment. Electrical covers rewiring, panel replacements, EV chargers, recessed and specialty lighting, surge protection, safety inspections and whole-home standby generators.
That mix reads as sensible once you know the housing stock here. North Seattle neighbourhoods around Greenwood, Ballard, Phinney Ridge and Wallingford are full of houses built between the 1910s and the 1950s, which means galvanised supply lines that have narrowed with scale, concrete or clay side sewers under mature maples, and knob and tube or undersized electrical panels that cannot carry a heat pump and a car charger at once. A company that does plumbing, drain and electrical work together can scope a whole-home problem instead of one symptom. Side sewer work in Seattle also involves its own paperwork, since side sewer repair and replacement permits are handled through the city and the line from the house to the main is the owner's responsibility, so ask who pulls the permit and whether traffic control or restoration is included in the quote.
The round-the-clock published hours are the other practical draw. Seattle winters rarely bring deep freezes, but cold snaps do arrive and they tend to burst pipes in crawl spaces and unheated garages, usually overnight. Wet season also brings sump pump failures and saturated yards in the low-lying parts of the city. If a mainline backs up on a Sunday, a company staffed for emergency plumbing is worth more than a slightly lower hourly rate on a Tuesday. Confirm before dispatch whether after-hours work carries a premium and what the visit fee is, because promotional terms on the website say free visits and estimates apply to major repairs or replacements, which is not the same as every service call.
The review record is the strongest single data point. Its Google Business Profile showed a 4.8 rating from 4,797 reviews when read on 26 September 2026. A sample that large usually means a multi-van operation running consistent processes, which is different in character from a two-person shop where you always meet the owner. Expect uniformed technicians, upfront quoting, financing offers and a membership programme the company calls Gene's Club. Some homeowners like that structure. Others prefer the flat hourly billing of a smaller independent, and for a simple faucet swap the independent may well be cheaper.
Worth asking about the promotional pricing, too. The site advertises things like a mainline clearing plus camera inspection deal and various dollar amounts off HVAC installations, each carrying terms and exclusions and unable to be combined. Ask which offer applies to your job, in writing, before work starts. Also ask for the camera footage after a sewer inspection, since that is your evidence for deciding between spot repair, pipe bursting and full replacement.
Two numbers appear publicly: (360) 218-7611 on the Google listing and a Seattle 206 number on the website, alongside online booking. Anyone comparing gene johnson plumbing with the other large Seattle home services firms should weigh the same things: response time, whether the technician diagnosing the problem is also the one selling the replacement, and how clearly the estimate separates labour, parts and permit costs. Get a second written quote on anything over a few thousand dollars. The company itself advertises free second opinions on major work, which suggests it expects homeowners to shop around.

Gene Johnson Plumbing FAQs
Is Gene Johnson Plumbing actually open 24 hours?
Its published hours list open 24 hours every day of the week, including weekends. That is the schedule shown on its Google listing, and the company advertises emergency plumbing as a service line. Ask when you call whether an after-hours or holiday visit carries a premium rate, since the published material does not set out call-out pricing.
What does it cost to have a Seattle mainline cleared?
The company advertises a mainline clearing with camera inspection at a set promotional price, with terms attached and no combining with other offers. Confirm the current figure and what happens if the blockage cannot be cleared, because roots in an old clay side sewer sometimes need cutting or hydrojetting rather than a simple cable, which is usually billed separately.
Do they handle side sewer permits?
Side sewer repair and replacement in Seattle requires a city permit, and the line from the house to the main belongs to the property owner. The company lists sewer line repairs, trenchless sewer replacement and city sewer hookups among its services, so ask directly whether the quote includes permit fees, traffic control and surface restoration.
How reliable is the review record?
Its Google Business Profile showed 4.8 stars from 4,797 reviews when read on 26 September 2026. That is a very large sample for a Seattle trade company and suggests consistent service across many technicians, though a high average across thousands of reviews still leaves room for individual jobs that went badly.
Can one company really do plumbing, HVAC and electrical?
Yes, and this one presents itself that way, listing plumbing, drain and sewer, heating, cooling and residential electrical as separate departments. In practice each trade needs its own licensed technicians, so ask which department is attending and whether the person quoting a heat pump is the same one handling the panel upgrade it may require.
Is it a good fit for a small repair like a dripping faucet?
It does that work, listing faucets, fixtures, sinks, toilets and garbage disposals, but a large company with a diagnostic fee structure is not always the cheapest route for a fifteen minute job. For minor repairs, get the total quoted before the technician starts. For repipes, sewer replacement or water heater work, the breadth and the 24-hour dispatch count for more.
Where is it based and which areas does it cover?
The address on its Google listing is 10011 Greenwood Ave N in North Seattle, near Greenwood and Bitter Lake. Its website publishes a service area page, so check that your neighbourhood or suburb is inside the boundary before booking rather than assuming coverage across the whole Puget Sound region.
Is Gene Johnson 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 Gene Johnson Plumbing serve?

Does Gene Johnson 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.
