Commercial doors play a crucial role in the security, functionality, and aesthetics of any business establishment. Whether it's a retail store, office building, or industrial facility, properly functioning doors are essential for smooth operations and customer satisfaction. However, like any frequently used equipment, commercial doors can develop various issues over time. In this comprehensive guide, we'll explore some of the most common commercial door problems and provide practical solutions for repairing them.
Problem: One of the most frequent issues with commercial doors is misalignment. This can cause difficulty in opening and closing, gaps between the door and frame, and compromised security.
Solution: To fix misaligned doors, start by checking the hinges. Tighten any loose screws and replace any damaged or worn hinges. If the problem persists, you may need to adjust the strike plate or realign the door frame. In some cases, shimming the hinges can help correct the alignment.
Problem: Doors that stick or bind when opening and closing can be frustrating for employees and customers alike. This issue is often caused by warped wood, swollen door frames, or improperly installed hardware.
Solution: Begin by identifying the exact location where the door is sticking. Sand down any areas where wood has expanded due to moisture. For metal doors, check for any bent or damaged areas that may be causing friction. Lubricating the hinges and weatherstripping can also help reduce sticking. In severe cases, you may need to plane the door or adjust the frame to ensure proper clearance.
Problem: Door closers are designed to automatically shut doors after they've been opened. When they malfunction, doors may slam shut too quickly or fail to close completely, posing security risks and potential injury hazards.
Solution: Start by checking the closer's tension and speed adjustments. Most closers have screws that allow you to fine-tune these settings. If adjustments don't solve the problem, the closer may need to be replaced. Ensure that the new closer is properly sized for the door's weight and dimensions.
Problem: Deteriorated weatherstripping can lead to drafts, energy loss, and water infiltration. This not only affects comfort but can also increase energy costs and potentially damage flooring or other interior elements.
Solution: Inspect the weatherstripping around the entire door frame. Replace any sections that are cracked, brittle, or compressed. When installing new weatherstripping, ensure a tight seal without impeding the door's operation. Consider upgrading to high-quality, durable materials like silicone or EPDM rubber for longer-lasting performance.
Problem: Panic bars or exit devices are critical for emergency egress. When these fail to operate smoothly, they can create serious safety hazards.
Solution: Regular maintenance is key to keeping panic hardware functioning properly. Clean and lubricate all moving parts periodically. Check for any loose mounting screws or worn components. If the device still doesn't work correctly after basic maintenance, it may need to be repaired or replaced by a professional locksmith or door specialist.
Problem: High-traffic areas can take a toll on door handles, causing them to become loose, wobbly, or even break off entirely.
Solution: Tighten any loose screws on the handle and its mounting plate. If the handle is beyond repair, replace it with a heavy-duty commercial-grade option designed for frequent use. When installing new handles, use longer screws that reach into the door's core for added stability.
Problem: Over time, heavy commercial doors can begin to sag, causing them to drag on the floor or fail to latch properly.
Solution: Check the hinges first, as they're often the culprit behind sagging doors. Tighten all hinge screws and replace any that are stripped or damaged. For more severe cases, you may need to install a continuous hinge or add a fourth hinge to better distribute the door's weight. In some instances, the frame may need to be reinforced or the door itself replaced if it has warped beyond repair.
Problem: Automatic door openers are convenient for accessibility but can be prone to various issues, including sensor malfunctions, motor problems, or control board failures.
Solution: Start by checking the power source and ensuring all connections are secure. Clean the sensors and check for any obstructions in the door's path. If these basic steps don't resolve the issue, it's best to call in a professional technician who specializes in automatic door systems. They can diagnose more complex problems and perform necessary repairs or replacements.
Problem: For doors with glass elements, foggy or cracked panels can be both unsightly and potentially dangerous.
Solution: Small cracks in tempered glass panels should be addressed immediately, as they can compromise the integrity of the entire panel. In most cases, damaged glass will need to be replaced entirely. For foggy insulated glass units, the seal has likely failed, and the entire unit will need replacement. Always use safety glass that meets local building codes when replacing commercial door glass.
Problem: Metal doors, particularly those in coastal or industrial environments, can develop corrosion over time, leading to structural weakness and unsightly appearance.
Solution: For minor surface rust, sand the affected area and apply a rust-inhibiting primer followed by paint matched to the door's color. For more severe corrosion, you may need to patch holes with automotive body filler or replace entire sections of the door. In extreme cases, full door replacement may be necessary. To prevent future corrosion, consider applying a protective coating or switching to corrosion-resistant materials like stainless steel or fiberglass reinforced plastic (FRP) doors.
Problem: Gaps under the door can allow drafts, pests, and water to enter the building, compromising energy efficiency and cleanliness.
Solution: Adjust the threshold if it's adjustable, or install a new threshold that better fits the gap. For uneven floors, consider a tapered threshold. Adding or replacing the door sweep can also help create a better seal. In some cases, you may need to modify the bottom of the door to ensure proper clearance and sealing.
Problem: Modern commercial doors often incorporate electronic access control systems. When these malfunction, it can disrupt business operations and compromise security.
Solution: Start by checking the power supply and all wiring connections. Clean card readers and ensure they're properly aligned. If the issue persists, you may need to reset the system or update its software. For more complex problems, consult with a security systems specialist who can diagnose and repair sophisticated access control components.
Maintaining commercial doors in top condition is essential for the safety, security, and efficiency of any business. While some repairs can be handled in-house with basic tools and knowledge, many issues require the expertise of professional door technicians.
