"Had a good experience overall. They had an opening in the schedule so were able to start quickly. Property had some plumbing buried in the floor that the crew had to work around and it was all done without any issues. Crew was professional and easy to work with. Haven't had any water issues since the drain and sump were installed several months ago--despite several big rains."

"Salesman was very accommodating and arranged a quick installation as the house was on the market already. Installers arrived promptly and worked quickly and efficiently. Work foreman was very easy to work with and took the time to explain everything. Work was finished in a timely manner. Work area was left clean. Two calls to the service dept. a couple of weeks later have gone unanswered. My C rating on responsiveness is a combination of an A for the sales rep and an F for the service dept."

"Worked with them to install french drain and sump in basement of home we recently purchased. There was an existing sump, but no french drain, and the location of the existing sump was inconvenient. Relocated sump to a corner where it was not in the way. Work was fast and efficient."

"They performed the work quickly and the guy was nice but the charge was 480 for a clearing a basement accessible drain. Got quotes from other for 150-350~ for clearing the same drain but wouldn’t come out as soon as DE plumbing pros. Seems very overpriced and wouldn’t use again unless I absolutely had to. Their customer service was good and theirs plumbers professional."

"Excellent work. Right after the installation, hurricane Ida hit. Not a drop of water. It all went to the French drain system, if anything penetrated. The smart jacks will prevent further buckling in the house due to secondary settling. Kudos to Andrew Troy and Matt!"

"I am so glad we made the decision to hire Worthington Basement Health Systems. Starting with Peter and his thorough explanation, he must say it a thousand times a day, but he had patience explaining our situation so that it made perfect sense. We had the pleasure of working with Corrinne in setting up the appointment, she made it seamless. And finally, what a great job Bolivio and his crew did on our basement. They were all very professional and knowledgeable. It was clear they had experience. Bolivio was very kind and we had complete confidence in him. We are so thrilled that we can now store our belongings in the basement worry free. We had many companies to choose from, and after doing a great deal of research, Worthington was clearly the best choice."

Foundation Drain Installation FAQs, answered by experts

If the time has come to install a French drain in your yard, basement, or crawl space, there's a solid chance you've been battling water damage—or the threat of water damage—around these areas. Thankfully, proper drainage should allow you to redesign these areas of your home without the fear of being inundated during the next storm. If you've had to remove a portion of your lawn for an exterior French or curtain drain, consider reseeding your lawn to patch up the spot. You can also take this opportunity to enhance your foundation waterproofing methods or even start thinking about finishing your basement .

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

There are a few possible sump pump drainage locations, including a neighborhood storm drain, into a creek or pond, or underground. Don’t let your sump pump water go into your sewer or septic system. Ideally, your drainage spot should be on a downhill slope that’s at least 10 to 20 feet away from your home’s foundation. Before choosing a location, check your local codes and regulations.
