Your chimney's crown and mortar joints serve as its initial and most critical defense against water intrusion — and they are often the first components to show signs of age-related failure. Once the crown cracks or the mortar joints erode, water finds its way into the masonry. Here in Renton, our frequent freeze-thaw cycles then cause this trapped water to expand, progressively breaking the masonry apart from within. We specialize in rebuilding deteriorated crowns, meticulously repointing and tuckpointing failing joints with color-matched mortar, and sealing the work to ensure your chimney effectively sheds water for many years to come.
In Renton, the combined forces of freeze-thaw cycles and consistent moisture exposure, particularly for homes near the Cedar River or Lake Washington, lead to much faster mortar joint deterioration than in more inland areas. Timely masonry repair in these locations can significantly extend the life of your chimney and prevent costly future rebuilds.

What's included
The chimney's crown and mortar joints function as the primary shield against water penetration – and, predictably, they are often the first elements to succumb to the effects of age and Renton's persistent wet weather.
How it works
We check the crown, joints and brick for water damage and movement.
Failed crown and mortar are rebuilt with color-matched materials.
A breathable waterproofer locks out future water intrusion.
Before/after photos of the restored masonry.

Why it matters
The crown and mortar joints are, quite literally, your chimney's umbrella and armor. Once the crown develops cracks or the mortar joints erode, water has a direct pathway into the chimney's structure. This water then freezes, expands, and rapidly accelerates spalling (the flaking of brick), liner failure, and unsightly interior leaks. Proactively repointing and rebuilding the crown early is a far more economical solution than the extensive, full chimney rebuild that inevitably follows years of unaddressed water intrusion.
If any of these sound familiar, it's worth a free inspection:
See the difference
The before shows a cracked crown and eroded joints at the top of the stack, where weather hits hardest. The after is a recast crown and fresh repointing that shed water away from the masonry. The crown is the chimney's first roof — once it cracks, water runs straight down into the brick and the flue, so fixing it early protects everything below.

Representative example of a typical masonry repair (crown / repointing) — not a specific customer job. We add photos of our own completed the Eastside projects as we finish them.
What this often looks like: a homeowner near the Cedar River spots a damp patch on the ceiling, and up on the roof the crown is cracked with the top joints eroded. The crown is the chimney's own roof — once it splits, rain runs straight down into the brick and the flue below. We recast the crown and repoint the top courses so water sheds off instead of soaking in. The stain quits coming back, and everything under that crown stays dry.
