As the owner of Porter Tuckpointing, I’ve spent decades working on the beautiful, historic homes that give St. Louis its unique character. I was recently driving through the Shaw neighborhood, admiring the turn-of-the-century brickwork, when I noticed a chimney with tell-tale dark streaks running down its sides. It was a classic sign of a failing chimney crown, a problem I see all too often. That seemingly small issue at the very top of the chimney is a major entry point for water, which can silently cause thousands of dollars in damage to the masonry, your attic, and even the internal structure of your home. It’s a subtle problem that quickly becomes a massive headache for homeowners, threatening the integrity of the very architecture we all love.
A cracked or deteriorating chimney crown is more than just a cosmetic flaw; it’s an open invitation for moisture intrusion. Here in St. Louis, our weather puts building materials to the test—from intense summer humidity and torrential downpours to the brutal freeze-thaw cycles of winter. When water gets into cracks in the crown, it freezes and expands, making those cracks wider and allowing even more water in. This cycle is the number one enemy of your chimney’s health. At Porter Tuckpointing, we specialize in expert chimney crown repair in Saint Louis, providing a durable, watertight seal that protects your investment. We have a deep understanding of St. Louis’s architectural styles and use locally sourced, period-appropriate materials to ensure our repairs are not only effective but also historically accurate and seamless.
Many homeowners confuse the chimney crown with the chimney cap, but they serve different functions. The cap is typically a metal cover that prevents debris and animals from entering the flue. The crown, however, is the concrete or mortar slab that seals the entire top surface of your chimney, directing water away from the flue opening and off the brickwork below. Think of it as the roof of your chimney.1 A properly constructed crown should have an overhanging drip edge that forces water to fall clear of the chimney’s vertical surfaces, preventing erosion and staining.
In the St. Louis climate, a faulty crown is a ticking time bomb. The moisture it allows into the brick and mortar can lead to spalling (flaking or peeling bricks), efflorescence (unsightly white, powdery deposits), and mortar joint deterioration. Over time, this structural decay can compromise the entire chimney, leading to the need for a costly rebuild. Our hyper-local expertise means we build and repair crowns using materials specifically chosen to withstand our region’s weather, ensuring a long-lasting solution backed by our Lifetime Craftsmanship Guarantee.
