What does Exterior Chimney Cleaning do?

Chimney exterior cleaning removes moss, algae, lichen, and debris from the masonry surfaces of your chimney. In the Pacific Northwest, moss growth is nearly universal on older chimneys — and left untreated, it accelerates mortar deterioration and traps moisture against the masonry.

• Moss and algae removal from chimney masonry
• Application of moss treatment to prevent regrowth
• Debris removal from chimney base and flashing areas
• Assessment of masonry condition during cleaning
• Coordination with waterproofing service for full protection

Protecting Your Home

Moss looks unsightly, but the real problem is what it does to your masonry. Moss roots penetrate mortar joints and brick faces, physically breaking down the material. Moss also retains moisture against the chimney surface, accelerating freeze-thaw damage.
