Deciantis Construction LTD specializes in providing general contracting services primarily to the ICI sectors (Industrial, Commercial & Institutional). We are continually striving to expand within the construction industry tackling projects ranging from hockey arenas to medium/high density residential buildings. At any point in time the projects undertaken by DCL vary in scope and complexity, ranging from simple site servicing and renovations to multi-million dollar projects built from the ground up. We are able to offer turn key projects in the commercial sector. This involves participating in the design and engineering process to meet the clients needs. We then manage and build the project to completion. Deciantis Construction LTD is able to provide its services in all of Southern Ontario. All projects are managed with a hands on approach from beginning to end.


Deciantis Construction was founded in 1966 by the Deciantis Family of Richmond Hill. The company’s original focus was on custom residential and light commercial projects. As the company matured it left the custom residential market to expand and grow in the ICI sector. Over 50 years later Deciantis Construction LTD remains family owned and operated.


Deciantis Construction LTD takes a hands-on approach to all projects. We strive to use our own forces as much as possible during the construction process. This allows us a greater amount of control over projects as well as flexibility. As a result, projects are completed in a more timely manner with the quality our reputation is known for. Our competitors are often unable to offer a similar degree of control over their projects.
