Chimney Waterproofing

Protect your chimney from moisture with quality waterproofing.

Overview

Waterproofing your chimney prevents moisture damage, which can lead to structural issues over time.

We use specially formulated sealants that allow your chimney to breathe while keeping water out.

Proper waterproofing extends the life of your chimney and prevents costly repairs.

Signs you may need it

  1. Water stains on interior walls or ceiling near the chimney
  2. Efflorescence (white staining) on the masonry
  3. Freeze-thaw damage on exterior bricks
  4. Musty odors from the fireplace

What happens on the visit

  1. We clean the chimney surface to ensure proper sealant adhesion.
  2. We apply a breathable waterproofing sealant to the exterior.
  3. We check for and seal any cracks or gaps that could allow water penetration.
  4. We inspect the work to ensure complete coverage and effectiveness.
