Sheet Metal and HVAC for Commercial Office Space and Tenant Improvements

Uncomfortable tenants don’t renew leases. Sloppy finish work doesn’t win the next project. Office buildings need mechanical work that runs reliably and looks right, inside and outside. We install sheet metal and HVAC for office buildings and multi-tenant properties across Oregon and Southwest Washington. Exterior architectural metal, interior finish work, and everything in between.

The Work Is Different Here

Office buildings have competing demands. Individual tenants have different comfort needs. Common areas and conference spaces have different requirements than tenant floors. Occupied floors mean noise restrictions and access coordination.

Tenant improvement work is its own challenge. A new tenant build-out has a hard deadline tied to a lease. We know that. We plan accordingly and deliver on schedule.

Exterior trim, cladding, gutter and flashing systems all need to look right from the street. Interior ductwork, exposed runs in lobbies and open-ceiling spaces, mechanical room enclosures. The fit and finish gets seen, inside and out. We fabricate these pieces in our Stayton shop and install them ourselves. Level hangers, tight seams, clean caulking. Functional and built to last.

Older buildings often have aging infrastructure. Rooftop units that haven’t been maintained, ductwork undersized for current occupancy, controls that are obsolete. We a

Common Questions About Office Building Projects

Can you work in occupied buildings?
Yes. We coordinate with building management and tenants to schedule work during low-impact windows. For critical systems, we plan carefully before anything goes down.
Do you handle tenant improvement HVAC work?
Yes. TI work is a significant part of what we do. We understand the lease-driven timelines and we deliver.
Can you work on older rooftop units and legacy systems?
Yes. We assess what’s there and give you an honest read on what can be serviced vs. what needs to be replaced. We don’t oversell replacements.
Do you install exterior sheet metal and interior sheet metal both?
Yes. Exterior trim, cladding, gutter and flashing on the outside; interior ductwork, exposed finish runs, and mechanical room enclosures on the inside. Our in-house fab shop builds custom pieces for both, and our install crew handles the whole scope.
Do you provide maintenance contracts for property managers?
Yes. We work with property managers on scheduled maintenance programs — filter changes, inspections, documentation. One less thing to manage.
What's your service area?
Our commercial team serves the four corners of Oregon and Southwest Washington.
