Chimney Waterproofing in Colorado

Breathable waterproof sealant that stops brick from absorbing water through Colorado's freeze-thaw cycles.

Brick is porous, it soaks up water like a sponge. At altitude, that water freezes, expands, and cracks the masonry apart. We apply a breathable waterproofing sealant that repels water while still letting the chimney release moisture, dramatically slowing freeze-thaw damage.

Signs you may need chimney waterproofing

  • Brick that darkens when it rains
  • Early signs of spalling or flaking
  • A recently repaired or repointed chimney
  • White efflorescence on the masonry
