KP Drains is a Wilmington drain and sewer company that says it has over 30 years of experience in sewer, drain cleaning and video inspections, and that it is open 24 hours a day, 7 days a week. In a recent Google review, a customer with a leak from their sewer pipe says Mike came out within 24 hours of calling and that it was quick and reasonably priced. In a 2025 review, a customer whose basement toilet and shower were not draining said Mike cleared the clog using a snake, including cleaning up the roots, and recommended checking again next year. In a 2023 review, a customer described snaking the drain on the first day to isolate the problem, then a camera inspection the next day, with technicians Andrew and Brandon. In a 2021 review, a customer said that after another drain company could not unclog their tub drain, Mike was there within half an hour and had the tub flowing within 10 minutes. In a recent review, a customer with a septic smell coming from the sink says he looked down the drain with a flashlight, declared it gunk build-up and advised bleach, and it still smells like septic. In a 2026 review, a customer said clearing a kitchen sink clog was followed by a severe backup in the bathroom, the technician told them to hire an outside plumber, and the office threatened collections over the $215 invoice. In a 2025 review, a customer said the company did damage to their brand new home and fought them every step of the way before agreeing to pay for the damages. In a 2024 review, a customer said they had to come out twice to clear the same clog, charged full price both times, and did not honor the 90 day guarantee for them.
Given the lengthy responses to critical reviews, I’ll simply say that my experience was consistent with the rating I’ve given.
They responded quickly. Otherwise, I didn't feel like they took my issue seriously. Septic smell coming from the sink, he looked down the drain with a flashlight and looked at (but did not touch) my under counter piping and declared it must be just gunk build-up (on my 2 year old sink) and to poor bleach down it occasionally. Did that, still smells like septic. Not satisfied with the end result.
We had a leak from our sewer pipe and Mike came out within 24 hours of calling. He was very professional, knowledgeable, and friendly. Couldn’t recommend him enough. It was quick and reasonably priced as well
They were so helpful with our drains. They froze and were able to promptly address and help the situation. Brandon and the guys over there were so friendly and answered all my questions with patience, grace and provided me with great advice and insight. 10/10 service!!!
I hired KP Drains to clear a kitchen sink clog. While they cleared that line, their work immediately caused a secondary, severe backup in my bathroom—a problem that did not exist before they arrived. Instead of taking responsibility for the shifted blockage, the technician told me he couldn't fix it and advised me to hire an outside plumber. I followed his advice and had to pay a local Watertown plumber $300 in cash for an emergency visit to fix the mess KP Drains left behind. When I reached out to discuss a fair adjustment to the $215 invoice, the office was aggressive, threatened me with collections, and made up details about the second plumber’s work that I never even provided. They are refusing to acknowledge the clear link between their work and the immediate secondary failure. Extremely disappointed in the lack of accountability and the high-pressure collection tactics for an incomplete job. I offered to pay 50% as a good-faith settlement, which they have so far ignored. Prospective customers should be aware of their "not our fault" policy if things go wrong.
