We've been repairing fire doors across Minnesota for over two decades. From Minneapolis high-rises to rural manufacturing plants in St. Cloud and Duluth, our crews know the local fire codes and building inspection quirks. We don't just fix doors — we make sure they pass your next annual inspection.
Whether it's a warped metal frame, broken panic hardware, or a misaligned latch, we handle it on the spot. No subcontractors, no runaround. Just real contractors who show up when we say we will. Call us today — we'll have your fire escape door back in service and compliant with Minnesota regulations.
Minnesota's extreme temperature swings and heavy snow mean fire doors face unique stresses. Frames warp, hinges freeze, and seals crack. We've seen it all — from subzero ice buildup on exit hardware to summer humidity swelling wood doors. Our crews know how to adjust and maintain doors so they work year-round.
We also stay current with Minnesota's specific adoption of the International Building Code and local amendments. That knowledge saves you from costly re-inspections. When we say a repair is code-compliant, it's because we've done it dozens of times for Minnesota inspectors.
Serving Minnesota and surrounding communities — local crews, fast scheduling, no call centers.
From glass storefronts to industrial overhead doors — we work on all commercial door types found in Minnesota businesses.
Heavy-duty steel doors rated for 90-minute fire protection. Common in stairwells and exterior exits. We repair dents, warped frames, and damaged self-closing hinges.
Often used in corridors and interior offices where aesthetics matter. Wood doors can swell in Minnesota's humid summers. We adjust clearance gaps, replace intumescent seals, and restore latch alignment.
The structural backbone of most fire doors. Corrosion from Minnesota road salt or moisture can weaken anchors. We weld, reinforce, and re-anchor frames to ensure a tight fit and proper fire rating.
Fire-rated glass panels in doors or sidelites. Broken glass or damaged gaskets compromise the fire barrier. We replace wired glass or ceramic panels and re-seal to maintain integrity.
Preparing Minnesota commercial doors for harsh seasonal conditions
Minnesota winters cause fire door issues you don't see in milder climates. Ice builds up under door bottoms, preventing proper closure. Steel frames contract in extreme cold, creating gaps that fail NFPA 80 clearance requirements. We adjust stops and install weather gaskets that still allow free swing even at -20°F.
Spring thaw brings its own challenges: frost heave misaligns thresholds, and moisture swells wood doors. Summer humidity can cause binding. We perform seasonal tune-ups to keep your fire doors operating smoothly through Minnesota's four distinct seasons.
Tip: Schedule a pre-winter door inspection in Minnesota before temperatures drop — closers and seals need adjustment to perform through subzero conditions.
Don't wait for a door failure to disrupt your business — watch for these common warning signs.
If the door doesn't fully latch when closed or drags open, it's a fire code violation. We adjust hinges, closers, and strikes to restore proper operation.
Minnesota inspectors measure bottom clearance precisely. A gap larger than 1/8 inch allows smoke to pass. We install new door bottoms or adjust thresholds to meet code.
The strips that expand in a fire to seal gaps can crack or fall out over time. We replace them to ensure your door provides full fire protection.
Minnesota's road salt and moisture cause hinges, closers, and panic hardware to corrode. Corroded parts can fail during an emergency. We replace hardware with heavy-duty, corrosion-resistant components.
