How We Help With Chimney Waterproofing

Brick and mortar are naturally porous materials that absorb water with every rain and snowfall. In Northglenn, repeated freeze-thaw cycles cause that absorbed water to expand inside the masonry, cracking brick faces and crumbling mortar joints in a process called spalling. Left unchecked, this leads to expensive tuckpointing, brick replacement, and eventually structural chimney damage. Professional chimney waterproofing applies a specialized water-repellent sealant that is vapor-permeable — meaning it blocks liquid water from entering the masonry while allowing moisture vapor trapped inside to escape outward, preventing the bubbling and peeling that paint or non-breathable sealants cause.

Superior Northglenn Chimney Sweeps uses industry-approved masonry waterproofing products that penetrate brick and mortar rather than simply coating the surface. Before application, we clean the chimney exterior and make any necessary minor repairs to cracks so the sealant bonds to sound masonry. The treatment is invisible once dry and typically carries an effective life of five to ten years depending on weather exposure. Waterproofing is most cost-effective when done proactively — treating sound masonry costs a fraction of repairing water damage after years of unprotected exposure to Colorado's weather.
