Brick is a porous material — it absorbs moisture readily and releases it slowly. On Long Island, where winters bring repeated freeze-thaw cycles and summers bring humidity and driving rain, an unprotected masonry chimney is constantly under moisture stress. Water absorbed into brick and mortar joints expands when it freezes, forcing apart the masonry matrix from the inside. Over years, this produces spalling brick faces, crumbling mortar, and eventually structural deterioration that requires costly repairs. Waterproofing treatment is the most cost-effective preventive measure available for any masonry chimney.

Albertson Chimney Sweep applies professional-grade, vapor-permeable chimney waterproofing sealers — not the film-forming coatings found at hardware stores that can trap moisture inside the masonry. Vapor-permeable formulas allow water vapor that is already inside the brick to escape while blocking liquid water from penetrating the surface. This distinction is critical: a non-breathable sealer can actually accelerate damage by trapping moisture.

Waterproofing is most effective when applied to chimneys that are in sound condition. We typically recommend completing any needed mortar repointing or crown repair before waterproofing so the treated surface is structurally intact. Most Albertson-area chimneys benefit from re-application every five to ten years depending on exposure. Service is available seven days a week throughout Nassau County.
