Why JMI? I enjoy working with the younger tradesman to create an understanding of what we can bring to the table through personal characteristics, work ethic, craftsmanship to benefit our employer and the customer. The owners are what sets JMI apart from other employers I have had pleasure to work for. Ownership at JMI is approachable and considerate of their employees compared to any other place I have worked.

Making a Difference.

JMI's second-generation dedicated owners spend a considerable amount of time establishing and maintaining personal connections between the families & communities to which we operate.

Specialized Trade.

Because of JMI's long-term social connections within the community... We have a deep knowledge of our industry, partners & suppliers, and most importantly our customers.

Complexity to Rapid Response.

Our company's structure enables management to have a shortened distance from the front lines, which translates over to effectively & efficiently deploying the right resources for a rapid response.

Family owned businesses aren’t particularly thought of as being innovative.

However, our skilled craftsman have not only received extensive training by means of the Western Washington Sheet Metal JATC apprenticeship program. JMI’s Employee Development program helps continue to advance skills and certifications to implement innovative results.

Building Information Modeling (BIM) was considered an industry “trend” over a decade ago. However, Johansen Mechanical was one of the first companies in the early 2000s to adopt the use of Revit MEP Software and begin integrating the BIM Model into our work processes. Although this was an investment in the beginning… Our proven methodologies have enabled robust communications and the ability to take a responsive approach to unforeseen or to potential problems throughout all stages of construction. This has enabled our team to meet our clients’ needs within the original estimated costs and minimize the amount of potential change-orders.

Johansen Mechanical, Inc. was part of the beta tester community for testing and giving feedback on one of the most recognizable and commonly used Mechanical Estimating Software – QuoteSoft formally known as QuoteExpress. This powerful solution has allowed our estimating team to generate on screen digital takeoffs to estimate labor, material costs for ductwork, pipe, fittings, etc. for a variety of Mechanical & HVAC projects.

Our Purchasing Department, Project Management Team, and Accounting Staff have utilized the Dexter-Chaney construction and accounting management software Spectrum for over the past 15 years. This system tied into our communitive process from QuoteExpress and Revit MEP software has enabled our team to provide robust/in-depth communications from between our internal operations as well as the partners, and trade members, clients, and owners to which we operate with on the regularly bases during all stages of construction.

In our shop, we have utilized a series of metal working technology that integrates with our CAD software to massively produce Mechanical & HVAC mechanical parts and assemblies, as well as our Architectural & Custom work.
