Peterson Sheet Metal is one of the leading, competitive mechanical systems contractors in Minnesota. We are a full service mechanical contracting firm offering preconstruction, estimating, design, installation, and maintenance services. Our main focus is to provide customers on time, exceptional quality and cost efficient mechanical systems.

PSM’s estimators are some of the leading professionals in the industry.

Because accurate estimates are essential to any project our estimators are assisted by leading edge technology to provide accurate and reliable estimates. We use on screen estimating software which gives us the ability to produce complete visual take-offs. Each estimate is customized to include details that assist all areas of the project. Estimates are done in collaboration with the entire pre-construction team to ensure accuracy.

We utilize digital estimating software, for the quantity survey of all piping, plumbing and ductwork systems, tailored to fit the variety of our estimating needs. These systems use labor units developed by MCAA for piping/plumbing and SMACNA for sheet metal work. Our team will evaluate each system to confirm its completeness and workability in conformance with the project requirements and has the ability to consider what is required beyond what is shown in order to provide a complete working system.

Currently, we are using the 2016 version of AutoCAD, Revit, Navisworks & Autodesk Fabrication programs to create construction documents and fabrication ready 3D models. We can also provide accurate and detailed estimates using our QuickPen Autobid Sheetmetal, and Quote Express Piping estimating software. Together, this allows us to track the progress of a project and correct any issues before they affect project milestones.

Our estimating system includes features that give us the ability to dissect and analyze an estimate’s various components by system and area. This offers us the ability to conduct a value engineering analysis through comparisons between budgets and estimates from similar projects and the utilization of alternate materials and methods.

The staff at Peterson Sheet Metal is well versed in all mechanical systems and capable of assisting with the design that best suits the owner and the most cost effective means of installation. Up front, accurate pricing means there are no surprises later.


From the first conceptual layout to the final construction documents, PSM’s pre-construction, estimating & project management team identifies our partners’ needs and translates that knowledge into an accurate representation of the project’s mechanical costs.
