We reached out to Koert Plumbing after experiencing issues with the plumbing system at our house.  The team was incredibly responsive, particularly on one occasion that was on a long weekend.  The crew is great and knowledgeable, and very transparent.  They took the time to explain the issue at hand and options around how to best remedy the matter.  The team managed themselves and the work in a very professional manner, and most notably, followed up with updates on progress of the work they performed.  All work was performed to a high standard. We have used Chris and his team on a number of occasions since, and would highly recommend them.

We had Koert replace our aging sump pump last spring. We hired them just before their staff was going on a company retreat, but Chris personally emailed me to let me know he'd be squeezing the job in before they left for the week. With their busy schedule, that could not have been easy.

The two gentlemen Koert sent out did a great job. They were courteous and efficient, and they took the time to explain everything about the pump and battery backup.

Highly recommend.

Chelsea Ranville on Koert Plumbing Ltd.

Our friends recommended Koert Plumbing to do our bathroom renovation, and we would absolutely recommend them, too! What impressed us most about Koert Plumbing—on top of turning our dated master bathroom into the most stunning room in our home—was the extensive amount of communication throughout the entire project. That's incredibly hard to find when working with trades, and Koert Plumbing gives you the peace of mind you need. Chris (and Tyler, too!) and the rest of the team were always available to provide updates, timelines, answer questions, and didn't need to be prompted by us to do so. Their recommendations during the design process were also spot-on and we are grateful for the guidance they provided while doing our project. As well, with any project, there were obstacles. However, Chris and the team navigated them so gracefully and were always able to resolve the issue. Chris and his team (including Jones Electric) didn't rest until things were resolved and we were happy. Chris takes a lot of pride in his work and in his team, and it shows. You can also tell that his team members enjoy working with him and for him. Thanks, Koert Plumbing, for a job well done!

I had all the plumbing replaced in my older house by Koert Plumbing. I was on a very tight timeline due to insurance required. They got the job done on time and in budget. Chris was very responsive to all my questions and everything was handled very professionally. Their communication on the project was fantastic. They took great care with even the smallest of details. I am very satisfied with the results of this job and would strongly recommend Koert for any plumbing work you need done.

This is my second project I do with Koert Plumbing and in both projects I am very satisfied with the work they have done. The first time Sean came in to replace my main water valve and the second project Costa replaced some old pipes in my laundry room. I can see the consistency of the professionalism in their staff. Chris the owner is very responsive and flexible in following up to setup the appointment. Angela the office Manager is also awesome and always on top of all emails responding and answering any questions either by email or phone. I will definitely continue use their service again. In my opinion, Koert Plumbing is a role mode of how a small business should be.
