Southern Iowa Mechanical

Southern Iowa Mechanical operates as a plumbing contractor in Corydon, Iowa, holding a 4.0-star rating across 29 customer reviews. Owner John Buttz launched his trade career in 1993 while still in high school, working across plumbing, HVAC, electrical, and mechanical disciplines in Millerton before advancing his skills at Cook Plumbing in West Des Moines for 21 years. There he earned Journeyman and Master licenses through ABC of Iowa and managed large projects with teams of 75 workers. The company returned to Corydon in 2013 and now employs 8 staff members serving both residential and commercial clients with integrated plumbing, HVAC, septic, and mechanical solutions.

The company distinguishes itself by offering multiple trades under one roof, eliminating the need for homeowners to coordinate separate contractors. Their service menu spans heating and cooling systems alongside comprehensive plumbing and drain cleaning, with particular expertise in septic systems and sewer solutions including root intrusion removal. This breadth allows them to handle complex jobs that span HVAC and plumbing intersections without callbacks to outside specialists.

Reviewers describe specific technicians handling urgent situations with notable responsiveness. One homeowner recounted calling on a Sunday afternoon about a backed-up sewer line and receiving same-day Monday service from Dawson, who cleared the line and explained tree root treatment protocols. Another reviewer noted the team arrived on a federal holiday to clear a mother's sewer backup, completing the work quickly. A third scenario involved emergency hot water heater replacement within 24 hours, with the team working through weather delays to restore service promptly.
