Commercial Mechanical Services

Mechanical Solutions

Randall Plumbing & Heating is one of Winnipeg's largest and longest-standing mechanical contractors. Throughout Manitoba, we provide mechanical construction, fabrication, plumbing, HVAC, design-build, service, and maintenance, all from one team.

We work extensively in commercial construction across pharmaceutical, healthcare, institutional, and commercial projects, handling everything from complex mechanical installations to the service call that keeps your building running.

Every project benefits from the same deep talent pool: experienced project managers, estimators, an in-house design and modelling team, and over 100 skilled tradespeople in the field.

Putting You First

Our approach is built on long-term relationships, which are built on doing the job right. That value still drives how our team works on every commercial project.

Expertise that improves the project

When we see an opportunity to improve a project, whether it's a design change that’s more efficient, a cost saving, or a more practical way to build it, we bring it forward. Engineers and consultants come back to us because we offer solutions, not just labour.

Professional from the field to the front office

From our tradespeople to our project managers, you'll deal with a team who is experienced, knowledgeable, and accountable. We do what we say we'll do, and we stand behind our work.

The best thing for the end user

Every recommendation we make starts with the same question: what actually solves the problem? Sometimes what a client asks for isn't what they need. We'll tell you when that's the case, then help you get to the right answer.

Our Process

Reach out

Send us your drawings to price, invite us to bid, or call our service team about an existing building. However the work starts, it starts simply.

2.

Estimate and plan.

Our estimators and project managers price the work accurately and transparently, and flag anything in the design worth a second look before it becomes a problem in the field.

Coordinated crews, off-site fabrication, and proven quality standards keep work moving on schedule, with minimal disruption to your site.
