Troubleshooting

Lintel sagging after installation.

Check the bearing length on both sides. Ensure the lintel is adequately supported during the curing process. Verify that the load does not exceed the lintel's capacity. Check the mortar for proper mix.

Difficulty aligning the lintel.

Ensure the opening is level and the correct width. Double-check measurements before installation. Use a level and shims as necessary to achieve correct alignment.

Corrosion observed on the lintel.

Assess the extent of the corrosion. Minor surface corrosion can be addressed with appropriate treatments. If corrosion is significant, consider replacing the lintel to maintain structural integrity. Check for sources of moisture and improve drainage.
