Family-owned St Louis union-based HVAC contractor

Sheet Metal Contractors’ History

Built on Family Values

Lawrence P. Krodinger, Sr. was a member of the first graduating class of St. Pius X High School in 1963. From there, he attended Flat River Junior College and Northwest Missouri State University. He began his drafting career with Wagner Electric. He then went on to work with Quality Heating from 1967 to 1980. It was in 1980 that he ventured out to start his own union heating and air conditioning business. The humble beginning for Sheet Metal Contractors with just four employees has grown to an impressive sixty full time employees.

Larry has three children, two of whom participate daily in the management of Sheet Metal Contractors. Kimberly Brown is the Vice President, CFO and Safety Administrator. Lawrence P. Krodinger, Jr. is the Director of Estimating.

“One of the best mechanical contractors in the region. Professional, prompt, reasonable and informed. Great People”
