Chimney Waterproofing in New Jersey

Brick and mortar absorb water like a sponge, and in New Jersey winters that water freezes and breaks the masonry apart. Ambassadors Construction provides chimney waterproofing in New Jersey using breathable water repellents that keep water out while letting moisture escape.

Waterproofing is the final step after repairs, and it helps repointing and rebuilding work last longer.

Why Breathable Waterproofing Matters

Sealing a chimney with paint or a non-breathable coating traps moisture inside the brick, which can make spalling worse. Breathable masonry water repellents penetrate the brick and mortar, repel liquid water and still allow water vapor to escape.

When to Waterproof Your Chimney

  • After repointing or rebuilding
  • When brick is absorbing water and darkening after rain
  • When efflorescence appears on the brick
  • As preventive maintenance on exposed chimneys

Repairs Come First

Waterproofing cannot fix cracked crowns, failed flashing or open mortar joints. We repair those first, then apply water repellent so the whole chimney is protected.
