Recommended Customer Reviews

The team help us cleaning and change the main pipeline, installing the 2-way clean out and installing get city approval. They are professionals with good experience and altitude. It's good experience working with them. Satisfied with the service they provided:)

Had a backed up bathtub that needed some attention. I was in contact with a rep in less than 30 mins. Scheduling the service was really easy and clear. I received text updates regarding each aspect of the job.
Axel and Edgar were knowledgable and could clearly articulate each aspect of the issue as well as details about how to fix the issue. I never felt rushed or pressured nor did they ever push for an 'upsell'. All repairs were clearly explained along with, what I felt was a fair price for the work being done.
I couldn't recommend them enough for your plumbing needs.

Knockout plumbing did an amazing job on our rental property. They are professional, have great communication and are a pleasure to work with. I would definitely recommend.

The sewer line in my apartment building was clogged in Saturday night of a holiday weekend. I called a couple of big plumbing company like Rooter Hero - no one called back. I contacted Edgar from. He immediately came and cleaned sewer pipe.
He was professional and honest. His price is very responsible compared with the price of big plumbing companies. I very recommend.

They gave me a quote of 900$ for one leaking tap !! That is preposterous and I hope they realize they are losing business by giving dishonest quotes like this.

We had a slow and clogged kitchen sink. Fast and quality work delivered within one day with a long warranty period. Thanks Edgar and team. Will get your help again in the future with any plumbing work.

The customer service is great; she sent the consultation on the same day when I called. Text message responding time was within 30 minutes; that's a plus.
Here is how they could have earned a 5 star in my opinion, if they could send a plumber who could identify the problem, provide me a quote, and fix it on-site, they could be a rockstar.
They sent someone over with ""free of charge""; that's new to me and it is a plus. However, the person who provided the estimation and consultation could not fix my shower tub cartridge/valve issue on site; they had to dispatch another technician to fix it later on.
Overall, they are good as a plumber company(Not knowing about the technical skills since I did not pay for their plumbing service). This review is solely for they customers service and their consultation. The consultant was able to identify the issue quickly on site.

Our kitchen sink was clogged. They did a good job snaking the pipe and clearing the clog. The price was also reasonable.

Edgar and the team did an excellent job on remodeling the shower and bathtub area for my home. The team is super professional, reliable, and efficient.
They come well-prepared and carefully protected my floor and the surroundings. Also, they cleaned up everything and took away all the disposals after their work.
Edgar is a very nice person. He is responsive and flexible in the whole process and in all of our communications. When the project is close the end, he kindly offered to help fix the surrounding walls and paint that was scratched before with no additional cost.
I would highly recommend Edgar and his team to anyone who needs a bathroom remodel or a plumbing project!

Two of our tubs were clogged and drainage cleaners didn't help. Edgar came at short notice after a same day appointment on a Sunday evening and helped us out. On time, polite and professional. Figured out the issue and explained to us, and gave upfront estimate for snaking. Reasonable pricing. Highly recommend.
