"My experience with this company was great. I was able to tell them my issues and they gave me several options. Ultimately we went for the full French Drain system. Everything was done on time and the estimates were very fair. Warranty on the work is great. I would call them again if needed."

"Once in a blue moon a person may find a contractor with whom they truly want to work--a person who values honesty, has expert knowledge, takes pride in his work, is conscientious, fair and punctual. In addition to these fine qualities, John was gracious, considerate and willing to go the extra mile. He installed a top-of-the-line French drain in my basement, which included features not offered by many of his competitors. It was done in 3 days, to the exact specs he kindly sketched out in response to my questions. When a glitch arose with the backup pump, his employee returned to do a quick fix the same day. After many years and much higher estimates, I finally have a basement that I feel will stay dry even in the worst of weather. I am very grateful."

"Drainage and Erosion Solutions installed a 130 foot drainage channel (an "armored swale") lined with fabric and 3'-8' river jack stone. They backfilled the eroded areas and stabilized the area between the street and the swale with gravel. We've received several compliments from neighbors who were impressed with the work. They also went above and beyond by mulching some adjacent areas. We would hire them again and highly recommend them to all."

"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."

"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"Came out within three hours of request to fix a leaking pipe under the sink. Plumber Carl was professional, careful, and respectful of property. Quoted a reasonable price and fixed the problem within an hour. Looked at other potential plumbing problems in the house and gave me quotes should I choose to pursue further repairs/improvements."

The regulations around whether drain pipe installers need to hold licenses or certifications differ based on where you live and the type of drain pipe installed. Municipalities have varying rules and regulations about who can and can’t perform plumbing work. However, we recommend hiring a certified plumber to install or modify your drain lines. Licensed plumbers will perform a high-quality, professional installation, which translates to a lower risk of clogs and leaks in the future. Use Angi’s state licensing tool to confirm the license status of your potential plumber before hiring them to install your drain pipe.
The cost to install a drain pipe is $600 on average, but the total can range between $150 and $2,000. Some cost factors that influence your project price include the type of drain, the area’s accessibility, the proximity of existing drain lines, and whether you’re installing a new drain or replacing an old one. Replacing the p-trap or s-trap under a single fixture will usually cost around $150, while replacing a main drain pipe can cost well over $2,000.
Plumbers will typically take one to two hours to install a new drain pipe, but that timeline can vary based on the area’s accessibility, the drain length, and the type of drain line. Replacing an easily accessible p-trap under a sink could take as little as a half an hour, while replacing a larger section of drain line behind the wall could take as long as three to four hours. When hiring a plumber for your specific installation, ask them to provide an estimated timeline to get a more accurate assessment.
You might need a permit to modify or repair any portion of your plumbing system, including drainage lines, depending on where you live. In some areas, simple replacements of existing drain lines don’t require a permit. We recommend asking your drain pipe installer or your local building department about permitting requirements. In many cases, only certified plumbers can pull plumbing permits, so you’ll usually need to leave the permit application to your professional. The fee for the permit will be passed to you on your project bill, though.
We highly recommend leaving the work of replacing drain pipes to a professional plumber. Drain pipes are a key part of your plumbing system, and making mistakes during the installation or even using the wrong size pipes for your specific fixture can lead to an elevated risk of leaks and clogs. Additionally, drain pipes prevent harmful sewer gas from entering your home, so hiring a professional plumber is essential to keeping the risk of leaks and clogs low and avoid reducing your indoor air quality.
