When Should You Call a Commercial Plumber?

If there is ever a time to call a plumber, it is when your production lines are stopped, or your kitchen can’t function, due to water supply or drain issues.  Not only do you need a plumber who is experienced with working in a commercial area, but you also need a clean and professional team, to ensure the work is performed as quickly and unobtrusively as possible.  Moving a sink and drain, or needing to relocate plumbing to meet ADA requirements in a restroom? Working on improvements in phases to match your budget? Stollwerck Plumbing can assist you in your commercial plumbing renovations! Whether you just purchased a new building and are wanting to make those necessary plumbing changes to attract tenants, or you just leased a new space and need to make those workspace changes to allow your business to function efficiently – we are here to help.

Commercial property managers should depend on their maintenance staff to notify them of any plumbing problems, but it’s best that a professional does the work to get the job done effectively and efficiently and in a way that will help avoid costly future repairs.

We’re at your service for any plumbing problems that may arise including:


New Plumbing

We’re here to help you with any new plumbing need you may have, from water lines to sewer and natural gas. Send over your set of approved plans and we can develop a reliable estimate for our services. We give you transparent pricing, professional consultation, and the confidence that it will be done right the first time.

We stand behind what we do 100%, so we take great care in using quality parts and delivering expert service in every job we do for you.

Whatever commercial plumbing needs you may have, give us a call. Whether installing new kitchen facilities, doing small piping or fixture change, or running entirely new lines to a manufacturing area, we have you covered.


Kitchen Drains

Signs that you should call a plumber to take a look at drains in the kitchen include a clog in the sink, gurgling noises, or foul odors. We’ll clear the clog and provide you with maintenance options. If it’s a mechanical issue, we can repair or rebuild drains for optimal performance.

For commercial kitchens in particular, you need to ensure proper drainage to stay up to code and to handle the grease and increased demands that a commercial kitchen puts on your drains and sewer lines.

Slow drain? Completely blocked? That’s when you need a professional plumber with the tools to do the job right the first time. What kind of drain are we talking about?

Office kitchen drains are subject to water, soap, and often food that tends to collect and clog the drain. Incorrect use of garbage disposals can add to the problem. Restaurant kitchen drains are even more susceptible to clogs simply because of their constant use and should receive regular maintenance to avoid potential down time.

Restroom Plumbing

Public bathrooms have multiple sinks, toilets, and floor drains… and they can all get clogs, backups, and breakdowns. Whether the clog is caused by soap, toothpaste, or hair, it needs to go, and we can do the job. For broken fixtures, toilets, and plumbing, we’re here to provide quick and cost-effective repair to get your facilities fully up to commercial code.

Floor Drains

Floor drains are common in restrooms, kitchens, warehouses, production facilities, and building maintenance areas. When they back up, dry out, or get clogged, they can produce foul odors and drainage problems. This can be a problem not only for you, but for staying up to code.

For foul odors, it may be a trap issue. By cleaning the drains and refilling the traps with water, sewer gas (which is often the cause of foul odor) won’t seep in.

We can scope your lines and diagnose the problem, clear your drains, and repair any problems we find while getting your business back on track.


Water Heaters

It’s obvious there’s a problem if you don’t have hot water from the tap in your kitchen. But if it takes longer to heat up or doesn’t last as long as it should, you may have a water heater problem.

If you’re not sure if you need a new water heater or a simple repair, we can provide a thorough assessment and practical and affordable solutions.

Another reason for getting professional help is if you notice rust in the tank. Tackling this problem before it becomes serious will save you money. If the rust problem is ignored, it can corrode the tank liner, allowing water to leak or the tank to fail. A water heater tank fail could end up damaging valuable materials or products and unexpectedly stop operations, when it could have been prevented and scheduled at a convenient time.

If you’re having any of these problems with your water heater, and it’s over seven years old, replacement instead of repairs is often recommended. Especially so if the cost of repairs will exceed half the cost of a new water heater.

We clearly lay out your options and the current state of your water heater and hot water plumbing so you can make an informed and smart decision.


Tankless Water Heaters

If you’re looking for energy efficiency and cost savings for the break room, a tankless water heater could be the answer. We can explain the advantages, such as the space saving design, cleaner water, and longer life, and if you decide to go with it, we can install it for you.


Sewer Line Repair/Replacement

Unfortunately, sometimes drain cleaning doesn’t reach the actual problem… which may actually be in the sewer line.

We’ll thoroughly inspect your sewer lines using a video system that enables us to see the exact cause of the problem. We fix cracks and breaks and damage caused by roots, freezing and corrosion, and get your drains running smoothly again without recurring clogs and backups.

If extensive repair and additional work is necessary, we can take advantage of trenchless pipe repair to get the job done faster than digging and with less disruption to your property so you can continue to do business.

Our motto

“Say what you’ll do and do what you say”

plumbing repair services Stollwerck plumbing

While it may be safe for a DIY home improvement enthusiast to undertake small repairs like a leaky faucet or a slow drain, trying to take on larger plumbing projects and more invasive repairs could end up costing more time and money… and probably more than one swear word.

Our service is not only quick and painless, it also includes a guarantee on our labor for 1 year… something unheard of in our industry. We value quality above all else.

System Maintenance

Stollwerck Plumbing and Sewer’s preventative upkeep and maintenance services are engineered to prolong the functional life of the pipes, drains and other components in your plumbing system in order to minimize the necessity for costly plumbing repairs.

Water damages a house quicker than you can imagine. A slow leak can be silently deteriorating the structure of your home, encouraging rot and black mold.

Regular maintenance even before a big problem hits is the best way to ensure the longevity of your home and avoid nasty surprises. No one wants to sell a home or do a remodeling project only to find damage hiding in the walls, floors, and foundation of their home.

Highly Qualified

Our team includes only fully licensed and insured plumbers, and no contractors. Further, we are a commercially licensed plumber, which means we’re able to provide our customers with the broadest scope of plumbing service options available for the most stringent of demands and standards.

Our client base includes many residential management companies that are responsible for ensuring smooth operations in apartment buildings and other multi-unit residences. They can’t afford to have shoddy work or parts. These professional managers trust us to help them stay on top of keeping their plumbing in top health to keep their tenants happy, and so can you.

Every plumber in Stollwerck Plumbing and Sewer is a licensed plumber who’s qualified to handle all of your residential or commercial plumbing needs. This is extremely rare in an industry where many plumbing companies utilize both contractors and unlicensed employees as part of their plumbing team.

We focus on top expertise at all times and with all jobs.

Liability Insurance

Washington State requires all plumbing companies to carry a certain amount of liability insurance. Stollwerck Plumbing and Sewer carries insurance well over that state-mandated amount. This adds an additional level of protection for our customers and enables us to participate in larger or more complicated projects that many of our competitors can’t take on.

Our Promise To Customers

At Stollwerck Plumbing and Sewer, customer satisfaction is our most important priority at all times. We use premium parts, replacement components and other products from top manufacturers because we want the work we do for our customers to last.

We make all manufacturers’ product warranties available to our customers, and we stand behind the work we do with a 1-year guarantee on labor. Most plumbers who offer warranties on labor offer only a 90-day guarantee, at most.

Since we first opened our doors for business two decades ago, Stollwerck Plumbing and Sewer’s motto has been, “Say what you’ll do, and do what you say.”

We believe in being completely up front and honest with our customers. We’ll never try to sell you plumbing services that you don’t need. Before we begin any work on your project, we’ll present you with a detailed estimate for our services, and if you don’t understand why we’re recommending a particular service option, we’ll be happy to address that recommendation with you.

When you choose Stollwerck Plumbing and Sewer, you’ll be working with a company that offers high-quality service and consumer protections.

From Bothell and Lynnwood, to Everett, Whidbey, and Snohomish.

We’d welcome the opportunity to tell you more about ourselves, so call us today.

Neglect, dis-use, and lack of known history with your plumbing and sewer systems can result in unexpected repair costs.  Proactive planning for repairs can give you peace of mind.  Call Stollwerck Plumbing & Sewer to evaluate, consult, and help plan your repairs, to mitigate the unexpected surprises in your home – (425) 374-3909!

Our evaluation process of analyzing why your current repairs are necessary may reveal root evidence of larger plumbing & sewer issues.

This husband & wife company was an absolute delight to work with from start to finish! Being a licensed real estate broker for nearly 25 years, I deal with a lot of contractors, and my experience with the good folks at Stollwerck Plumbing was one of best I’ve ever known. Their crew was incredibly thorough, and quickly determined & resolved the issue. It’s so rare these days to encounter a company that offers such a refreshing and enjoyable level of care & service!

Rich Jacobson

Best service in town, honest, reliable, and they know what they are doing. I was so happy and impressed with the service I received from Stollwerck plumbing. They were professional and great at calling back and communicating to setup a job to fix a big leak on my water main. This was a big job and they gave me an honest price and stuck to it, I actually paid what I was quoted. They arrived on time and after digging out the leak and making the repair they filled it in and restored my yard as if nothing had happened. I will call on them for all my plumbing needs and you should too. This all happened during covid when other contractors weren’t even returning my calls.
