For over 45 years, DILFO Mechanical has gone beyond the build, delivering high-quality mechanical systems, innovation, and trusted partnerships across Ottawa’s largest ICI projects.
Others follow industry standards. We help define them.
DILFO has set the benchmark for mechanical contracting in Ottawa and Eastern Ontario. As a second-generation, family-owned company, we bring together deep technical expertise, advanced fabrication capabilities, and a culture built on accountability and teamwork.
From design through delivery and beyond, we ensure every system performs exactly as it should — efficiently, safely, and built to last.
From design-build to large-scale retrofits, we deliver customized mechanical contracting solutions. With in-house piping and sheet metal fabrication, and advanced VDC/BIM capabilities, we have decades of experience in Industrial, Commercial, Institutional (ICI), and high-rise residential construction.
Our commitment extends beyond installation. With proactive maintenance programs and 24-hour emergency HVAC and plumbing services, we keep systems running at peak efficiency and reliability. All backed by real-time digital tracking and expert technicians.
Discover how DILFO Mechanical has gone beyond the build to help shape Ottawa’s most important facilities, from healthcare and education to retail, industrial and hi-rise residential.
