About Us
Mazza Mechanical Company



Founded in 1932 as Mazza Bros., the company specialized in sheet metal fabrication as well as heating and ventilation systems. In 1965, the company was officially incorporated as Mazza Sheet Metal, with Joseph DeRose serving as managing partner. By 1974, Joe was the sole owner of the business. Truly a family-owned and operated business, Joe’s four sons spent many years working in the field and office, getting their hands dirty and learning the trade. In December 2004, Mazza purchased the Buffalo, N.Y., Linc Service® franchise and followed that up with the nearby Rochester franchise a few years later. With the Linc Service® franchise, the company had the opportunity to grow its service business. Through the decades, Mazza evolved from a two-person sheet metal shop into a thriving, full-service mechanical contractor that employs over 100 people throughout the region. Today, Mazza designs, engineers, installs, and maintains each system in house, and stands behind its work to ensure complete customer satisfaction.
