Our Values

The most important thing that we build at DILFO is relationships. Strong relationships give us strong teams capable of working together to reach our goals, and the goals of our clients. We create teamwork through open and honest communication, and are aligned in our promise to never let our clients down. We strongly believe that a good team is created when you include people with different backgrounds, ideas, and experiences and work to create an environment where every team member knows their value and impact on our success.

From start to finish – from our shop fabrication to our site installations to service and maintenance – everything we do is about the quality. We source quality material, hire quality people, and choose to work with partners who also believe in the importance of quality. We feel that every project we work on is an opportunity to reaffirm why a DILFO job is always considered a quality job.

Staying adaptable and open-minded is what keeps us fresh and keeps us moving forward. We are unafraid of finding new and innovative solutions for our clients, and our team is an industry leader in integrating leading edge technology into our day-to-day processes. We know that innovation isn’t only for the equipment we work with, but also for creating the best processes in planning, project management, and communication.  Being adaptable keeps us at the forefront of the industry, and serves our drive to be continuously improving at what we do.


Our core focus defines who we are as a company and keeps us focused on the areas where we excel. It comes from the intersection of knowing “why” DILFO exists and “what” we do.

DILFO is a company that stands out from others in our industry because we manage to do two important things very well; our Core focus is that DILFO is that we are Big Enough to Deliver and Small Enough to Care.

We have a great team here who can tackle large and complex projects, and every one of our employees has pride in our work and cares about our clients and what we do for them. This is why our clients continue choosing DILFO.

Integrity is a founding principle at DILFO, and can be truly considered our guiding principle in all work and decision making. Integrity keeps our employees safe, it keeps our client relationships strong, and it keeps us moving forward on the right path. We have made a commitment to always make the right choice – when we work with integrity, we do the right thing for both our team and our clients.

With 41 years of experience installing mechanical systems, the Ottawa construction industry knows it can always have confidence in the work done by DILFO. Our clients choose us because they know that we have their best interests at heart; we plan ahead in order to solve problems before they happen, to save on project costs, and to deliver work that stands the test of time.  We are proud to have a reputation for being responsible and accountable in our work.
