Preparing Hanover commercial doors for harsh seasonal conditions
Minnesota winters cause thermal movement that can warp fire door frames and break seals. Annual freeze-thaw cycles also affect door closers and hinges. We install doors with winter-grade hardware and set clearances to accommodate temperature swings.
Spring thaw and heavy snow loads can damage fire door thresholds and bottom seals. Our Hanover-specific inspections check for these issues, and we replace components that have deteriorated from moisture or ice damage.
Tip: Schedule a pre-winter door inspection in Hanover 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.
A fire door must self-close and latch from any open position. If it sticks or bounces back, the fire rating is compromised. Call for service immediately.
Gaps larger than 1/8 inch around the sides or top of a fire door allow smoke and flames to pass. We measure and adjust or replace the door to meet NFPA code.
Every fire door has a label showing its rating. If the label is painted over, damaged, or missing, the door is no longer code-compliant and needs replacement.
Rust on steel fire doors or frames weakens the structure and prevents proper operation. Especially common in Hanover's humid summers and salty winter roads.
