Brick is not waterproof. Despite appearances, fired clay brick is a porous material that absorbs rainwater readily — and once water enters the masonry system, the damage cycle begins. In Charlotte, where spring thunderstorms and occasional winter freezes are facts of life, untreated brick chimneys absorb water, which then expands as it freezes, causing brick faces to pop off (spall) and mortar joints to crumble at an accelerated rate.
Joseph's Chimney Sweeps applies professional-grade, vapor-permeable chimney waterproofing sealers that penetrate the masonry surface and repel water from the outside while still allowing moisture vapor to escape from within. This is critical: sealers that trap moisture inside the masonry can actually accelerate deterioration. The products we use are specifically formulated for chimneys and rated to reduce water absorption by up to 99.9%.
Waterproofing is best applied after any necessary masonry repairs — tuckpointing, crown work, or brick replacement — so that the sealer locks in an already-sound surface. When paired with a properly installed chimney cap and correctly lapped flashing, a waterproofed chimney represents a fully moisture-managed system that will require far less maintenance over its service life in the Charlotte climate.

Common Questions
Is chimney waterproofing the same as painting or sealing the brick?
No. Standard masonry sealers and paints create a film on the brick surface that traps moisture inside, which accelerates spalling. Chimney-specific waterproofing products are vapor-permeable — they repel liquid water from outside while allowing water vapor from combustion and interior humidity to escape safely through the masonry. Using the wrong product can cause more harm than leaving the brick untreated.
How long does chimney waterproofing last?
Professional-grade vapor-permeable chimney sealers typically last 5–10 years depending on sun exposure, rainfall intensity, and the condition of the masonry surface at the time of application. We recommend combining waterproofing with your periodic chimney inspection to evaluate when reapplication is warranted.
