"So far, so good. The finished project looks great; it really hasn't been tested yet as there has been little or no rain. Groundwater used to flow through the cellar after heavy rains so we'll see it the subsurface floor drain works. The floor looks good, the price was right (lowest of three bids) and Beth was very helpful and available to answer all my questions. At the moment, I'm very happy."

"Nate communicated with me quickly when I posted my job to fix an outdoor spigot and replace a toilet. He had availability right away, but it turned out that I didn't need him for several weeks. He was able to do the job when I needed him at a very fair price, managed the job well & left things cleaner than he found them. His business is fairly new, but he is a Master Plumber with a lot of professional experience and a very nice guy. We all need a dependable plumber on call, and I've found mine. Hope you'll give him a call on your next job!"

French Drains questions, answered by experts

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

A saturated leach field can result from various underlying issues, so it's best to call a professional septic company to diagnose and treat the problem. Depending on the cause of the saturation, potential fixes include pumping out a full septic tank, adding more bacteria to the tank, or regrading the soil to fix low spots. It may also be necessary to reroute rainwater and runoff away from the leach field using gutters, downspouts, and extenders. Once the primary issue is resolved, planting specific types of vegetation over the area can help absorb excess water. In more severe cases, you might need to install a larger septic tank or replace the leach field entirely.

Clearing typically takes 1-2 hours, depending on the blockage size and location.

This depends on the location of the blockage. If the blockage is in your home’s system, anywhere in the system, it is your responsibility as a homeowner. Blockages seldom happen because of items or buildup coming from the city, which means it originates in the home. It becomes the city’s responsibility at the exact point your home’s line distributes waste into the city’s system. The exception is if the problem in your home damages the city lines.  

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.
