What Are Weep Holes And Why They Matter
Weep holes are found at the bottom of window frames and in masonry walls. Their primary function is to allow water that has penetrated the wall or frame to drain out and prevent water from accumulating inside. In sliding glass doors, weep holes are located in the track area.
Importance of Weep Holes in Sliding Glass Doors
1. Prevent Water Accumulation: Weep holes’ primary purpose is to drain rainwater or condensation that may collect within the door frame.
2. Mold and Mildew Prevention: Trapped moisture can lead to mold and mildew growth, which can be a health hazard. Weep holes help by allowing water to escape and keeping the area dry.
3. Structural Integrity: Weep holes are also important for the structural integrity of the sliding door system. Excess water can weaken materials, which leads to rot or deterioration. Proper drainage through weep holes mitigates this risk.

Tools & Materials Needed For Cleaning Weep Holes
1. Clean Towels or Rags: For wiping down surfaces and removing debris.
2. Compressed Air Canister: To blow out any dirt or obstructions from the weep holes.
3. Crevice Tool: A small tool to help reach and clean out any built-up debris inside the weep holes.
4. Spray Lubricant: Teflon or silicone lubricant for maintaining the door's functionality (avoid WD-40).
5. Wire Hanger or Similar Tool: To dislodge any stubborn blockages within the weep holes if necessary.
6. Garden Hose (optional): To test the drainage after cleaning by spraying water at the weep holes.
Step-by-Step Guide To Cleaning Weep Holes

Clean weep holes every three months to maintain the quality of your sliding door.
Step 1: Locate the Weep Holes
Locate the weep holes at the bottom of your sliding door's track.
Step 2: Remove Debris
Wipe around the weep holes to remove visible debris - this will prevent clogging during the cleaning process.
Step 3: Clear Blockages
- Use Compressed Air: Direct the nozzle of the compressed air canister into each weep hole to blow out any accumulated dirt or debris.
- Crevice Tool: If necessary, use a crevice tool to reach deeper into the holes and dislodge stubborn blockages.
Step 4: Check for Obstructions
Insert a wire hanger or similar tool into the weep holes to make sure there are no remaining obstructions. Gently probe to break up any clogs that may be present.
Step 5: Lubricate (Optional)
If you notice any stiffness in the sliding mechanism, apply a small amount of spray lubricant around the weep holes and track area.
Step 6: Test Drainage
Now, you can test the weep holes by spraying a small amount of water at them using a garden hose. Check outside to see if water drains effectively through the weep holes.
Step 7: Final Inspection
After cleaning, perform a final inspection of the area to check if all debris has been removed and that the weep holes are functioning properly.
Preventing Future Clogs In Weep Holes
1. Routine Maintenance: Schedule regular cleaning of the weep holes every few months or more frequently in areas with heavy rainfall or dust.
2. Check Installation Quality: Make sure that your sliding glass door is installed correctly, with weep holes positioned appropriately to drain water effectively. Misalignment can lead to clogs.
3. Install Screens or Filters: Consider adding screens or filters over the weep holes to prevent debris from entering while still allowing water to drain.
4. Maintain Slope: Check that the bottom track of the sliding door is slightly sloped toward the outside to facilitate water drainage away from the door.
