My water softener needed reprogrammed, so Brandon did that, ran tests on the water and ser it up for regeneration, which I didn't even know was a thing ! He, like everyone else from Lantz, was very polite and professional. He even added a few bags of salt for me! Love Lantz Plumbing

Michelle DeWine-

We called Lantz to get an estimate on adding a water softener to our water line. Mark came out and gave us an estimate and he also walked around with us and gave us ideas and suggestions about other things we want to do. When we decided to go forward with Lantz, Mark came back, right on time and got right to work. It was a big job and he handled it like a pro. We thought we were going to have to spend another $1500 on our master bath, but he helped us figure out a different solution to that. We would definitely use Mark and Lantz again.

Lisa Pittman-

Brandon was very diligent doing the installation of our water softener and did an excellent job cleaning up afterwards. I'd be more than willing to use Lantz' Lakeside Plumbing again.
