In a bustling city like Toronto, commercial doors are vital for keeping businesses secure, efficient, and accessible. When a commercial door doesn’t close properly, it can lead to security risks, energy loss, and even operational disruptions. At Delet Door Systems, we understand how crucial it is to address these issues quickly and effectively. Here’s a practical guide to help you troubleshoot common reasons why a commercial door might not be closing correctly.
Whether it’s a matter of tightening hinges, adjusting the closer, or realigning the latch, this guide walks you through each step. And if the problem persists, remember that a professional service can make all the difference.
1. Identify the Problem: Why Isn’t the Door Closing?
Understanding the root cause of the problem is the first step to a successful fix. Here are some common reasons a commercial door might struggle to close:
- Misaligned or Loose Hinges: Hinges that aren’t secure or aligned can cause the door to hang unevenly, which might prevent it from closing flush.
- Obstructions or Dirt: Accumulated dirt or small objects in the door frame can hinder the door’s movement.
- Worn-Out Door Closer: A door closer that’s worn or improperly adjusted may not pull the door shut all the way.
- Latch or Strike Plate Issues: If the latch doesn’t align with the strike plate, the door won’t latch.
- Weather-Related Expansion and Contraction: Toronto’s variable climate can affect door materials, impacting how they close.
2. Tighten or Adjust the Hinges
If loose hinges are causing your door to sag, the fix might be as simple as tightening the screws. Here’s how to address hinge-related issues:
- Check the Screws: Use a screwdriver to tighten any loose hinge screws. If screws are stripped, try using longer screws for a more secure hold.
- Adjust Hinges for Alignment: If the door is slightly out of alignment, loosening one hinge slightly and adjusting the door’s position can help it close properly.
- Add Shims if Necessary: If alignment remains an issue, you may need to add shims between the hinge and door frame to achieve a flush fit.
3. Clear the Doorway and Inspect the Latch
Sometimes, the issue is as simple as an obstruction in the doorway or latch.
- Remove Any Debris: Check for dirt, pebbles, or small objects that may be caught in the door frame or bottom. Clean the doorway thoroughly to ensure a smooth path for the door.
- Examine the Latch and Strike Plate: Dust and debris can build up in the latch mechanism, preventing it from engaging. Clean this area with a cloth, and consider applying a small amount of lubricant to the latch for smoother operation.
4. Adjust or Replace the Door Closer
A malfunctioning door closer is often a primary cause of commercial doors not closing correctly. Over time, door closers can weaken or require adjustments.
- Adjust the Closer Screws: Door closers have screws that control closing speed and latching force. Adjust these screws to see if the door closes better.
- Inspect for Wear: If you see oil leaks or significant wear on the closer, it’s likely time for a replacement. In high-traffic areas, door closers can experience heavy use and may need periodic replacements.
5. Realign the Latch and Strike Plate
A door latch that doesn’t align with the strike plate can prevent the door from closing or latching securely.
- Move the Strike Plate: Loosen the screws on the strike plate and adjust it up or down until it lines up with the latch. Tighten the screws once it’s positioned correctly.
- Inspect the Latch Mechanism: If the latch itself is sticking or not retracting properly, cleaning it and applying lubricant can help. In cases of wear, replacing the latch may be necessary.
6. Consider Seasonal Shifts and Temperature Changes
Toronto’s seasonal shifts can impact the fit and function of commercial doors. Materials like wood and metal expand and contract with temperature changes, affecting the way doors close.
- Install Weatherstripping: Adding weatherstripping can help mitigate gaps caused by expansion and contraction, keeping the door aligned and minimizing drafts.
- Seek Professional Adjustment: If seasonal shifts significantly impact your door, a professional technician can make adjustments to help the door withstand temperature changes.
When to Call in the Professionals
