LBP knows MSP.

Founded as Loop Mechanical and merged with Belden-Porter, we've been around since Minneapolis was powered by steam. Today, we're a full-service mechanical contractor offering mechanical service and construction to properties in the Twin Cities and beyond. From plumbing and pipefitting to HVAC and boilers, we've done it all. Now, we're ready to work with you.

From restaurants and night clubs to retail and office space, commercial mechanical construction is where we're most experienced.
