"Shane Flagg and his partner Doug (knowledgable retiree) are highly professional. Their work is efficient and complete. Erica Dole (in the office) scheduled the date/time quickly. I value the company for their work and their individual friendliness, and will welcome them back to add a 'riser' to the tank. Thanks to you all. Alan Baker"

Sewer Cleaning FAQs, answered by experts

It is generally safe to stay in a house that smells like sewage for a short time, but you should get the problem fixed as soon as possible. While the level of sewer gas is usually low enough to only cause minor symptoms, prolonged inhalation can lead to headaches, nausea, or respiratory irritation. High levels of gas exposure can be more dangerous, and high concentrations of methane—a component of sewer gas—can pose an explosion risk in enclosed spaces. If you smell sewer gas in your home, ventilate the area and call a professional to locate, assess, and fix the problem, as it will not go away on its own.

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

Costs range from $200 to $600, depending on the severity of the blockage and access difficulty.

It can take anywhere from one month to a couple of years for tree roots to grow back in sewer lines. Tree roots can cause extreme havoc on your sewer lines, potentially cracking them and causing untreated wastewater to make its way into the groundwater. Have a landscaping pro remove trees and roots before installing your system, or call a pro to do it retroactively as soon as you can.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.
