Welcome to Adelio’s Contracting

History of Adelio's

After emigrating from Italy in 1969, Adelio DiFranco worked for a local contractor for several years. In 1976, he started his own company, Adelio’s Electric Sewer Cleaning Company.

Adelio’s Electric Sewer Cleaning Company started off with Adelio and his brother-in-law. They specialized in drain repair services as well as basement waterproofing. They also bought sewer snakes to be able to clean residential drains of all sizes. They kept the company small and manageable with just a few dump trucks and a service van. 

In 1985 Adelio purchased his first sewer jet (or hydro jet), which is used to clean mud and debris and to cut stubborn tree roots inside downspout drains, drain tiles, footer drains, and sewer pipes. 

Business started gravitating towards the Heights neighborhoods on the east side of Cleveland because neighbors continued to recommend us to one another. 

We have found that there is no advertising, quite like a recommendation from a neighbor!

Adelio’s son, Sergio, began working with him on summer breaks and loved riding along in trucks to help his dad. After graduating from Cleveland State University with a degree in Business Management, Sergio came back to work with his father and started growing the business on the foundation that Adelio built. 

Sergio became to owner of the company in 2006 when Adelio retired. Through his vision and leadership, Sergio was able to significantly expand Adelio’s Contracting to be able to help additional customers in both the Heights and new neighborhoods. He focused on carrying on the morals, values, and high-quality craftsmanship that Adelio had founded the company on. In 2024 Sergio was able to retire from the business and remains an advisor to the business and leadership team.

In 2024, Alex Alten, who served as Sergio’s Operations Manager and had been with Adelio’s Contracting since 2011, stepped into the role of General Manager. Having worked closely with both Adelio and Sergio, Alex is deeply committed to carrying on the values and mission on which Adelio’s Contracting was founded. He is dedicated to maintaining the company’s family-oriented culture, delivering high-quality work, ensuring strong customer satisfaction, and supporting continued growth to better serve the community.
