"Had a backup a few days before and wanted to determine if it was a simple clog or cesspool related. They sent out a tech (Jimmy) the same day. He located both cesspools and walked me through my options. He was honest and patient, answering all my questions along the way."

Customers say: Terrific value

"Jack is a straight shooter and goes over the problems he sees and only positive solutions. Jack is personable and tried to save you money versus over sell unnecessary improvements. We need our foundation patched for leaks and his crew went over and beyond the work we thought we needed. Waterproofed our outside issues and then waterproofed the inside with paint. They cleaned up our crawl spaces as well as under the basement stairs. Jack even threw in a fire extinguisher and 2 water detectors. Great man, proud of what he does and loves to please his customers. HIghly recommend. Oh, his crew keep everything clean and when they left you would never have known they dug into our driveway and backyard to install leader drains from our gutters."

"Pros: VERY fast response time. I had a small leak in the kitchen. It was not an emergency, but they had someone at my house in 2 hours even though it was a Saturday. The technician gave me an estimate, had all the parts, and fixed it in less than 2 hours. Work was fine. Cons: Very expensive. Replacing the drain, basket and trap cost $870. It was worth it to me for the speed, but I was quoted $480 from another company if I could wait a week."

French Drains FAQs, answered by experts

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.

As a general rule of thumb, it’s best to clean your linear drain every two to three months to prevent debris buildup. However, if you notice it draining slowly or an odor from your drainpipes, it’s best to clear the clogged drain and maintain it more often. If you let a clog go for too long, you may have to invest in the price of professional shower drain cleaning, which costs about $225.

Professionals use augers, hydrojetting equipment, and cameras for precise clearing and inspection.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.
