Waterproofing
Sun-driven moisture, freeze-thaw, and why masonry waterproofing choices must respect evaporation and breathability.
Water damage is often about drying
Brick facades can usually handle some wetting when they can dry. Trouble grows when coatings, failed joints, roof runoff, or poor drainage keep moisture in the wall.
Common moisture clues
Efflorescence, paint failure, spalled brick, dark staining, and damp interior plaster can all point to moisture movement.
- Check gutters, downspouts, parapets, and caps.
- Look for hard coatings that may trap vapor.
- Watch for patterns that appear after specific storms.
Waterproofing should not be a shortcut
Breathable repair, drainage correction, flashing, and compatible mortar often matter more than applying a coating over unresolved defects.

FAQ
Can waterproofing sealers damage brick?
Some film-forming products can trap moisture. Product choice should match the wall, exposure, and drying needs.
What is efflorescence?
Efflorescence is white salt residue left behind as moisture moves through masonry and evaporates.
