About Us

Dunford-Liscio (Ontario) Inc. is a mechanical contractor with more than 45 years (since 1969) operating experience in the GTA.

Who We Are

Dunford-Liscio is an expert in mechanical renovations. We execute mechanical changes including heating, ventilation, air conditioning, plumbing, electrical, refrigeration, air balancing and ducting that ensure your building’s occupants live, work, study, play and operate in a comfortable environment. With a high profile institutional, general contractor and building owner client base, we are focused on renovation projects where complexity of design, tight timelines and space constraints are the norm. Dunford–Liscio’s in-house estimating, sheet metal design and manufacturing, and project management combined with owner attention to project needs results in a high level of satisfaction for our clients.

What Makes Us Different

What used to be called “know-how” fits into our role. When the ductwork fits, when the heating and air conditioning works quietly and cost effectively, when the system accommodates heat gain and heat loss caused by the building’s envelope, and when the “real world” impacts of climate change require operating flexibility, it’s our forty plus years in business and the expertise we bring to each project that can bring huge client benefits – timely performance, quality execution, client centred and cost competitive.

Code Of Ethics

Your Renovations Specialists

Renovations are different from additions and new building construction because of the building “envelope” constraints as well as the previous construction’s limitations. So having a contractor whose core skill is dealing with tight geography, adapting and customizing around previous infrastructure, and completing the work on time and on budget are significant benefits to you.
