"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

The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is  $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.

If used correctly and sparingly, root killer shouldn’t damage your pipes. Make sure to follow the instructions on the back of the bottle or the company’s website to avoid any unintended damages. However, when it comes to copper sulfate, it’s better to avoid it. This type of root killer can damage your plumbing and the surrounding environment.

Yes, hiring a drain cleaner is worth it, especially when compared to the cost of not being able to use a sink, shower, toilet, or bathtub and the potential damage that flooding can cause in your home. You might try a temporary drain cleaning liquid or snaking it yourself, but if the clog is out of reach or these methods do not work, then hiring a professional drain cleaner is the way to go.

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

Unlike regular cleanings, snaking your sewer line should be done as needed. There’s no reason to snake your sewer line if you don’t have any noticeable issues, like slow drainage or plugged drains. You can add it to your regular sewer cleaning checklist as a prevention method (on the same 18- to 22-month schedule), but it’s not always necessary.
