"Potential future customers deserve transparency so that is prompting this review. Be prepared to pay their hourly rate for their travel time plus a mileage rate. We were charged 3.5 hrs at $114/hr for an install of a water heater (that we supplied) and that included 30 minutes spent in his truck writing up the invoice. Then, for the boiler check which took him about 15 minutes, we were charged 1 hour at $130/hr. Total time from drive in to drive out of our driveway was 3 hrs, 48 minutes. Between the inflated labor costs and up-charging of supplies, consumables, mileage, and drive time, we paid over $800. Calling to question the charges only prompted rudeness. We will never use them again and do not recommend to others."

Sewer Cleaning questions, answered by experts

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Yes, sewage smells can originate from a floor drain. If the P-Trap in the floor drain dries out or if there's a clog or other issue in the plumbing system, sewer gasses can escape through the drain, causing nasty odors. Regularly pouring water into the drain helps maintain the water seal and prevent those smells, but if the smell persists, you should have a plumbing professional inspect the drain for potential problems.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.
