"Professional and honest service. Michael is the sole proprietor of this local business. He knows his stuff but will not try to scare you into buying more than you need. We paid him to come out and give us a thorough diagnostic of the problem with our sewer pipes. The price I paid for him to diagnose my pipes was fair and I hope to hire him to do the actual fix."

"Immediate call back when requested quote, and great service. Crew workers are hard working and respectful. The work performed went way beyond the basics... from cutting down 3 ft weeds, removing debris, spraying for weed control, trimming under bushes, cleaning up edges of flower bed, and then spreading bark. I would hire them again, and recommend this company ?."

Sewer Cleaning FAQs, answered by experts

The type of clog in your sewer main determines the required cleaning method. Different types or methods of sewer main cleaning require various tools like chemicals, mechanical removal, or a combination of both. Some of the most common types of sewer main line cleaning include:

  • Minor debris removal: $100–$600

  • Tree root removal: $100–$1,000

  • Trenchless pipe repair: $60–$250 per linear foot

  • General line repairs: $1,000–$4,000

  • Full pipe replacement: $3,000–$25,000

Professional tools include drain snakes, hydro jets, cameras for line inspection, and enzymatic or chemical cleaners for dissolution.

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

Never pour used motor oil down the drain. Doing so can have serious environmental consequences, including contaminating groundwater, endangering animals, and killing vegetation. It can also clog your pipes, causing backups in your plumbing or the wastewater treatment plant. In most places, pouring motor oil down the drain is illegal, whether you do it in your home or a storm drain.
