Zach is a consummate professional. He was thorough, timely, efficient, personable, and diligent. He returned the next day after the job to place a cover on a part, which is something my partner & I wouldn’t have known. Clearly, he has integrity, which in my book is paramount. We emphatically would not recommend anyone else, but him and his team for plumbing jobs. We were beyond pleased with Zach’s skill and caliber. 20/10 ⭐️

Zack and his crew replaced my kitchen sink drain after it started leaking. I was really happy with the price, and the speed and quality of their work. It was also easy to get a quote and schedule over the phone. I would definitely hire Knockout Plumbing again in the future!

Zach has done a number of plumbing jobs for us over the years ranging from large bathroom additions to smaller repairs, every time they've been top quality. I highly recommend Knockout!

I cannot recommend Knockout Plumbing and specifically Colin Forster enough! I was in a bind trying to sell my house from across the country and the buyers had some plumbing related requests before agreeing to move forward. Colin was super fast to get back to me, understand the asks, assess the actual work, and complete the fixes. He was so understanding and patient, walking me through what needed to be done and handled it all super quickly so we could proceed with getting the house sold. It's hard to find people you can trust, especially when you're no longer local to a place, and I really felt like I can trust Colin and the team. They were amazing! Definitely use them for any of your plumbing needs!

There is nothing but great things to talk about this experience from beginning to end. I leave a message - Colin calls me back and we discuss the projects. He calmly addresses a plan. We get it scheduled, he shows up, does great work, answers my questions, and leaves everything looking and working great. No hesitation, hands downs, highly recommend Knockout Plumbing!

Updating since I just used knockout plumbing again. Great service. Diagnosed the issue quickly and charged me minimal for the trip out. Will continue to use. First time: Great service. Came fast. They basically taught me how to use my house as a newer home-owner. And didn’t charge me the full fee since it was a simple task. Gave me tips to prevent issues. Knowledgable so will use again!
