"The job was done very well and on time. They also had helpful suggestions along the way. Matins not only replaced the septic system, they also did concrete work and replaced the house. All of their work was done very well. They are also very friendly, professional, and easy to work with. I highly recommend them!"

"We had French drains installed from backyard to the street due to flooding in our backyard and going under our house (mild drainage) from neighbors downspouts and our own. The neighbors consented to adjoining their downspouts to the drain so that all water was rerouted to drain between the houses toward the street. The job was done March 3-7th. We have had very good results. Our yard no longer floods. A vapor barrier was placed in our crawl space in addition to a sump pump should there be any further flooding. Also fungus along one wall in crawl space was treated. A lot was done in a short time and we felt they were very reasonably priced as compared to other bidders. Jess demonstrated a lot of patience and reassurance when we were overly concerned about certain things due to our ignorance of how things work. We would hire them again."

French Drains FAQs, answered by experts

Bleach—even diluted bleach—is not always the safest option for cleaning your drains. With a high pH, bleach can be highly corrosive to many types of pipes, especially when used regularly. When mixed with household cleaners and organic waste, it can also create dangerous chemicals. Remember to use proper protective equipment and ventilation when dealing with bleach.

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

Costs vary by severity and access requirements. Typical pricing ranges from $100 to $350, increasing with complexity or for emergency services.

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.

Yes, hiring a drain cleaner is worth it, especially when compared to the cost of not being able to use a sink, shower, toilet, or bathtub and the potential damage that flooding can cause in your home. You might try a temporary drain cleaning liquid or snaking it yourself, but if the clog is out of reach or these methods do not work, then hiring a professional drain cleaner is the way to go.
