Southern Iowa Mechanical

About Us

John Buttz, owner of Southern Iowa Mechanical, began his career in 1993 in Millerton, Iowa, while still in high school, gaining valuable hands-on experience in plumbing, HVAC, electrical, and mechanical work. After graduation, John honed his skills at Atcheson Plumbing in Kansas, later advancing his expertise at Cook Plumbing in West Des Moines for 21 years. There, he climbed the ranks to manage large projects and oversee a team of 75, while earning his Journeyman and Master licenses through ABC of Iowa. John returned to Corydon in 2013, starting Southern Iowa Plumbing from his home. Under his leadership, the company has grown to 8 employees and offers comprehensive plumbing, HVAC, septic, and mechanical services for both residential and commercial clients.

On 2/17/2025 Judy Craven had this to say:
0 degrees and our furnace stopped working. WYATT from southern Iowa plumbing was here within 3 hours, got right to work and in less than 1 hour he had heat on. Wyatt was very polite and very knowledgeable about his job. I will personally recommend wyatt to anyone. Testimonial written by Judy Craven on this site.

On 2/7/2025 Nicole Muir had this to say:
The service from the owner, John, and his staff was top notch. We woke up to our old hot water heater no longer working and they had it replaced within 24 hours, where other companies said it would take atleast a few days. They were all very polite, quick, and informative…despite some weather conditions that had everyone closing and running behind. We will definitely be calling Southern Iowa Plumbing first from now on.

My mother's sewer was backed up and they came the same day on a federal holiday. They had the line cleared of tree roots quickly. Will definitely use them again.
