Huge shoutout to Isiah Zinda for fixing our leaking toilet. I have now used knight plumbing twice for plumbing emergencies and both times they have really knocked it out of the park. If I could give them 10 stars I would.

I continue to utilize Knight Plumbing. The first time I used Knight Plumbing was on New Years Eve day in 2019. My upper bathroom shower drain failed and was pouring water into my son’s room. Even though they were scheduled with appointments that day, they were able to dispatch 2 plumbers to fix the issue in less…

Nicolas K. came to my house recently to unclog my sewer lateral. Even though he ran into some very unexpected situations he managed to fix my issue and did an excellent job and was very respectful and also did a good job at cleaning up. I highly recommend Nicholas and Knight Plumbing!

I was very pleased with my service. I elected to do some extensive work in my basement - remove old house trap and replace with new line, replace toilet stack. Also updated water heater. Nick and Brad answered my questions. Big project that took a little longer than I thought but very pleased overall.

Same day, exceptional service. I had an appointment for drain service with another company who never showed up. Reached out to Knight plumbing, got a response immediately and had a technician at my home within the hour. Knowledgeable staff, fair pricing and Dan got the job done fast & efficiently! I would definitely recommend.

The person was knowledgable, experienced, and did the job competently. My house was built in the '50. He recognized what he was up against. The problem was a basement drain to the street blockage issue. A roots-driven problem. Would call them again for the same issue or other plumbing issues.

I discovered water in my basement on a Friday afternoon. Knight Plumbing being a local outfit was the first I called and lucky for me Isiah was at my house within 30 minutes. He assessed the situation, discussed my options and we agreed on a course of action. Unlucky for me additional work needed to be done however,…
