Our master bath tub was not draining and nothing seemed to help unclog it. We were referred to Knockout plumbing and they were immediately responsive. Martin came to the house, gave us a quote and his crew was available to do the job on the same day! They were professional, courteous and got the job done quickly. One of the most impressive things they did was to wear shoe covers while in our house to minimize any dirt and debris. After, they collected all their trash and hauled it away.There was an issue after the job was complete and Martin was immediately available to assist us. He was able to provide a solution and send his crew to resolve it. Overall, they provided excellent customer service and focused on quality to get the job done right. Definitely highly recommended for plumbing needs and would use them again.
Jason and his team worker came to have the free estimate for my crawl basement issues is rainwater seepage . He is professional, easy to communicate with. Best thing is Jason aimed for the root cause, not just the symptoms of current issues having a sincere and patient attitude. Thank you!
Knockout did an excellent job for us and I highly recommend them. We started our journey with an estimate to replace all the vertical and horizontal waste water pipes under our home. Our house is 70 years old and we noticed cast iron pipes that seem to be deteriorating. We looked it up and their life rage is about 70 years so we bit the bullet and got estimates from 4 different companies. They all seemed good but Knockout offered some things the others did not. They offered a 25 year transferable warranty, they acquired and arranged for permits. They also put back the dry wall that they had to removed to do the job. The man that did the texturing did a great job. He matched the 70 year old texturing style that was in our family room. I was truly amazed. This sewer pipe replacement, grew to include all the water pipes, and then to replace the sewer line from the house to the street and unknown to use we had a second line that was leaking under our garage floor. This turned into a really really big job. It could have been a nightmare but it was not. Martin, Axil and the rest of the crew totally took care of us and our house. Every day I would receive an email telling me when they would be there to work or when an inspection was happening. They were the most cautious and careful of our house. They protected my floors, and carpet and walls. THEY NEVER LEFT A MESS EVER.I watched them clean, sweep and scrub down our driveway when they had used it as a work space. They were absolutely incredible. Clean, neat, work that was approved by the city and sewer department and great communication with us the entire time. I HIGHLY RECOMMEND THEM IF YOU HAVE ANY PLUMBING NEEDS BUT ESPECIALLY IF YOU HAVE A BIG JOB.THANK KNOCKOUT, YOUR WORK ETHIC KNOCKED ME OUT.Susan and Mark Kontich
I loved Knockout Plumbing. They exceeded expectations with communication and I really appreciate this! I would highly recommend them. They did a full replacement of piping under the house, which was built in the 50s. Top Notch. I love Martin and Axel - they were great!
Professional and knowledgeable crews. I had a project for a whole building repiping for a multi unit residential housing and contacted 6 plumbing companies around. Knockout is the most cost and time efficient repiping company among all of them. Their pricing is reasonable and they know what they are doing. Those guys kept their promises of the project timing despite of working late. They coordinated with the tenants and went above and beyond to ensure for a quality delivery. They take ownership of their responsibilities with the tenants and are very professional. We got all the repiping done with permit on time. Extremely grateful for their services!
