Preparing Mendota Heights commercial doors for harsh seasonal conditions
Minnesota's freeze-thaw cycles can warp door frames and cause alignment issues. Our security door installations account for ground movement and extreme temperature shifts. We use weatherstripping rated for -30°F and adjust hinges to prevent binding in subzero weather.
Snow and ice buildup around thresholds can compromise security. We install heavy-duty bottom sweeps and raised thresholds to keep moisture out and prevent freezing locks. Regular seasonal maintenance checks are available to keep your doors operating smoothly year-round.
Tip: Schedule a pre-winter door inspection in Mendota Heights 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 security door doesn't close and latch with a firm push, the frame may be shifting or the strike plate misaligned. This creates a security gap that can be exploited.
Dents weaken the door's structural integrity, while rust indicates moisture damage. Both reduce forced-entry resistance. Inspect exterior doors after every winter.
A missing or torn door sweep leaves a gap underneath that can admit water, pests, and intruders. Replace it immediately to maintain a tight seal.
Sticky keypads, loud grinding, or keys that stick signal failing hardware. Security depends on reliable locks — don't wait until a break-in reveals the problem.
