You may have noticed a powdery white substance forming on your brick or stone surfaces. That’s called efflorescence, and while it’s not dangerous, it can be a sign of bigger issues.

How to Fix and Prevent It
- Cleaning – A simple water and vinegar solution often works to remove light efflorescence. For tougher stains, use a specialized masonry cleaner.
- Waterproofing – To prevent moisture from entering, a masonry sealer can be applied after cleaning.
- Professional Help – If efflorescence keeps returning, contact masonry contractors near me Chicago. They can identify the source of moisture and may suggest repointing or tuckpointing to keep your walls sealed and dry.
Pro Tip
