Chris H. came out to do an estimate.
Not only was he knowledgeable, but also a good communicator. Seems straight- forward and honest!

Mark was great! Easy to set up the appointment, Mark arrived in the window I was given and took care of everything in my concern. I will use Southside in the future!

I really really like my plumber, Chris! Today he replaced the PRV and house shutoffs. It was a big job, but he left everything looking better than before (including full moisture barrier replacement). He fixed a big pressure issue I was having. He's very cheerful and fun to work with.

Trevor and Gabriel were very quick in answering our request on having our toilets. After examining all three of them, we were advised that they could be repaired but replacement was the better option . After Trevor patiently answered all our questions, we agreed and Heather called us later to make our appointment. Trevor and Adam came out on time and were very professional in their demeanors and finished the installations very effectively. There was no mess left and they carted off the old toilets. We are very happy with the work they performed. And we especially like the soft close lids and seats. We would highly recommend Southside Plumbing.

We have used Southside Plumbing in the past with very good results. This experience was just as good if not better. We had a toilet replaced. Chris was very knowledgeable, honest, professional and efficient. He informed us of the different options and did a great job installing the toilet. We felt like we were in very good hands and would definitely use Chris and Southside Plumbing for future repairs and projects.

I had a great experience with Southside Plumbing! It began with Mark assessing my failing tank water heater and providing me options to prolong its life and options for replacement.
My wife and I decided on moving forward with a new Navien tankless water heater and a Halo whole house water filtration system.
Mark, Adam, Trevor, and Isaiah performed with excellence to remove the old tank and install the new systems all within a day.
We have been enjoying the improved water quality and endless hot water with the new systems.
I highly recommend trusting Southside Plumbing with all of your plumbing needs!
