"I contacted Fred by email first, as on his website, it says you can either call or email. But there was no response to my email for a couple of days, so I decided to call. Fred asked me to text him my address. He made an appointment to come to the house a couple of days later. He came on time, drilled a hole through the concrete block in the basement and installed a new faucet. He added a bleeder valve to the copper pipe and explained how I should bleed the pipe after turning off the inside valve before the cold winter months. Fred was pleasant and informative. He did a good job. It took about an hour and 15 minutes. To contact Fred, you might want to send him an email explaining the work needed, and include your phone number so he can call you back. Or send him a text that includes your address."

"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."

"They installed an entire weeping tile system with 2 sump pumps. Everything was done in a quick and clean matter. After the next rain there was a small leak in the basement and they came back the next day and fixed the issue."

"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."

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.
