What is a rusting lintel?

Corrosion, also known as rust when the term is applied to steel lintels, causes the lintel to expand or bloom. The expanding lintel exerts pressure on the surrounding brick or stone work, resulting in cracks and movement. I see this a lot, even in homes that are otherwise very well maintained.

How do you fix a rusty lintel?

How Do You Fix a Rusted Lintel? The lintel will need to be cut out, removed, and replaced. It should also be painted with a quality exterior paint, to seal and protect it from the elements.
