Winter temperatures in Minnesota cause steel doors to contract and seals to crack. A local contractor understands these effects and installs with proper clearance and weatherstripping. That keeps your fire door functional year-round.
Serving Lakeville 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 Lakeville businesses.

Fire-rated glass panels integrated into a steel or wood frame. Provides visibility for security without compromising fire protection. Common in Lakeville schools and hospitals.
Required by code for exits serving high-occupancy spaces. Includes push bars, exit alarms, and self-closing mechanisms. We install full assemblies that meet Lakeville fire marshal requirements.
Preparing Lakeville commercial doors for harsh seasonal conditions
Minnesota winters cause metal frames to contract and wood to swell. A fire door that fit in summer may drag in January. We adjust hinges and thresholds to maintain proper closing speed all year.
Snow and ice buildup against exit doors can block egress. We recommend installing weatherstripping and sweeps that seal tightly without impeding operation. Our Lakeville team checks these details every visit.
Tip: Schedule a pre-winter door inspection in Lakeville 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 your fire door sticks or doesn’t fully latch, it won’t contain smoke or flames. This is a code violation and a safety hazard. Call us for immediate replacement.
Moisture in Lakeville’s humid summers and salty winter roads can rust steel door edges. Rust weakens the fire rating. Replacement is often faster than repair.
Every fire door must have a visible UL label. If it’s painted over, damaged, or missing, the inspector will flag it. We can provide a new labeled door quickly.
Code requires fire doors to have tight clearances around the perimeter. Gaps larger than 1/8 inch allow smoke and fire to pass through. We replace the door or adjust the frame.
