Preparing Mendota Heights commercial doors for harsh seasonal conditions
Minnesota winters are brutal on doors. Freezing temperatures can cause metal frames to contract, throwing off alignment and making doors stick or fail to latch. Ice buildup in thresholds and hardware also prevents proper locking. Our technicians see these issues every winter in Mendota Heights and know how to adjust for seasonal expansion and contraction.
Summer humidity and heat can warp aluminum doors and cause panic bars to bind. After a freeze-thaw cycle in spring, we often find loose hinges and cracked welds. DJ Commercial Door offers seasonal tune-ups for security doors to catch these problems before they become security breaches. Don't wait for a door to fail mid-weather.
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 rubs the frame or threshold, the hinge alignment or frame is shifting. This can damage hardware and prevent proper latching – a security risk.
A sticky panic bar is a code violation and a safety hazard. It may be due to a broken spring, dirt buildup, or misalignment inside the bar mechanism.
Intermittent holding power or constant buzzing means the magnet or power supply is failing. Don't rely on a door that might not lock when you leave.
Faulty wiring, dead backup batteries in the strike, or a damaged reader can lock you out or leave a door unlocked. Get it diagnosed before it fails completely.
