"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

"Using MasterServ is a perfect example of the pros and cons of using a big company. They were able to offer a lower price (by several hundred dollars) than other estimates I received because they specialize in volume (and not necessarily quality). The estimator who came was extremely pleasant and professional, however, internal communication in this company is a disaster. Therefore, small details like getting a new shower valve installed and installign new shower heads were initially overlooked by the installers because this wasn't communicated between the estimator and the crew. I never met the so-called project manager, who should have been there the first day to make sure everyone was on the same page about what was to be done. It was explained to me by the estimator that it would be a two-day job (true). The first day, the crew showed up and spent about two hours cutting holes in the walls and prepping the house. The second day they were there from 7 AM until 830 at night, working like crazy to get it done that day -- very stressful. When I saw that they hadn't installed the new shower valve, I got some grief from the crew and the so-called project manager over the phone, and this was eventually rectified with me paying an extra $200 to have the crew come back for an hour or so to install. When the job was complete they had disconnected and capped some old galvanized pipes, but with the new water pressure they blew out a couple weeks later (because they make their money by moving fast, quality and client communication suffer!). The guy they sent to do the drywall patching was a total incompetent. He showed up a couple days after the plumbing work was done started work and left mid-day saying he'd be back the next day to finish, though he never did return. I called the so-called project manager who was surprised to hear that the job wasn't done and it took a few more days for them to schedule a new guy to come out who had to re-do everything because the first guy was incompetent. In the final analysis, this company was the cheapest alternative, but there were a lot of headaches -- stay on top of them and make sure they do the work correctly!"

"The sink was leaking after but at least it drained. We paid in cash, much more than what we paid last time we had it fixed by a different plumber, but we weren't willing to shop around and just paid the price."

"Rocky was very professional. I sent pictures of what I needed done and he bought the materials and came on time. He completed the plumbing problem and insured me that if the leak came back, that he would come back. I will definitely hire him again."

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.
