"I discovered my 10 year old water heater had developed a pretty good leak and called the branch located in Hudson, WI. Brian answered my call and he was very attentive to my needs, quoted me a better price than I was finding elsewhere, and was able to schedule an install in a very short time. I really appreciated his help and understanding of my situation. The install went great and my new water heater is functioning as it should! I'm definitely a repeat customer should the need arise!"

Sewer Cleaning questions, answered by experts

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.

Snaking a drain can take as little as a few minutes for small, simple clogs, up to two hours or more for tough clogs located further down the drain line. For tougher clogs, a professional drain cleaner can likely get the job done much more quickly because they have the necessary tools and expertise. However, your drain cleaning pro might not be able to give you a firm time estimate until inspecting the clog and its surrounding plumbing.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.
