When you need an emergency plumber or a drain cleaner, call Roto-Rooter Plumbing & Water Cleanup. Your fast & reliable plumber can fix any plumbing problem, including sump pumps, toilet repair, faucet repair, faucet replacement, garbage disposals, water heaters, bathtubs, showers, and outside faucets. Roto-Rooter is best known for drain cleaning & sewer cleaning. We fix drain clogs, clogged toilets or sinks, blockage of main sewer lines, slow draining shower and bathtub drains, sewer lines and leaking or burst pipes. We also specialize in water damage restoration & water cleanup services. We can fix and clean up your flooded basement too. Roto-Rooter is a 24-hour plumber near you and provides emergency service.
"The Roto-Rooter plumber was great and explained everything clearly. He fixed the issue and left everything neat and clean. The reason for the 4 star is they were supposed to call 30 mins before arrival. They showed up without calling and I had to rush home from work. The 4 stars is also due to sticker shock (no fault of the plumber). Original quote was $720 for a clogged drain. They knocked it down to $500 with only a 30 day warranty rather than 6 month. He found the clog at 35’ (10’ beyond my 25’ snake) in less than 20 mins. I now know I can get a 125’ power snake with all the different pipe size attachments for $300. I do appreciate the promptness of Roto Rooter, ease of scheduling, and fixing the issue right away, but I will invest in my own 100’ snake before spending $500 for 20 mins of labor (not including their travel). Thanks Roto Rooter for jumping on this and fixing the issue in less than 24 hours after contacting you."

FAQs for boiler installation projects in Williams Bay, WI
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.
It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
