Preparing Cottage Grove commercial doors for harsh seasonal conditions
Minnesota winters cause metal doors and frames to contract, leading to gaps, drafts, and sticking. The freeze-thaw cycles in Cottage Grove can also crack welds and loosen hardware. We adjust door alignment seasonally and recommend weatherstripping to maintain a tight seal.
In summer, high humidity can swell wood cores and cause hinges to bind. Routine maintenance keeps your security doors operating smoothly year-round. Our crews inspect for seasonal wear and address issues before they become emergencies.
Tip: Schedule a pre-winter door inspection in Cottage Grove 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 latch fully or leaves a gap, it’s a security risk. Common causes are misaligned hinges or a worn strike plate. We can adjust or replace parts to restore proper closure.
Cracks, rust, or bends in the door frame weaken security. Often caused by impact or moisture. We assess the damage and either repair or replace the affected section to maintain structural integrity.
A sticking lock cylinder can indicate internal wear or misalignment. Forcing it may break the key or lock. We lubricate, repair, or replace cylinders to ensure smooth operation and reliable access control.
A door that scrapes the floor signals hinge sag or foundation settling. This can damage the door and create a tripping hazard. We adjust hinges, trim the door, or realign the frame as needed.
