Keep Your Chimney Protected & Free of Water With Professional Crown Repair Services Provided by Chimney Doctors of Colorado
Most homeowners don’t spend much time thinking about the cement slab at the top of their chimney stack – and to be fair, you shouldn’t have to. If your chimney crown was properly constructed and is maintained and inspected annually, you shouldn’t have to worry about whether it’s effectively keeping moisture out of your chimney. However, there are concerns. The chimney crown constantly battles the elements: moisture, sun, and freeze/thaw cycles can cause any crown to crack and crumble over time, especially if it wasn’t built to high standards. A cracked or crumbling crown compromises its ability to keep moisture out of the chimney system, leading to potential damage.
When you suspect chimney crown damage or you see signs of water intrusion, call the team at Chimney Doctors of Colorado. To set up an appointment for a thorough chimney inspection to determine the source of your problem, call us at 303-838-3009
What Does a Chimney Crown Do?
A chimney crown is a concrete slab that sits atop the chimney stack, serving as a protective barrier for the masonry below and the flue system inside. Its primary purpose is to direct water away from the chimney to prevent damage to the bricks, mortar, and interior components. Without a high-quality crown, water can seep into the structure, causing cracks, leaks, and other forms of deterioration.
A lot goes into making a high-quality, long-lasting, and effective crown. If the individual or team building the crown is inexperienced or uneducated, the results will be sub-par. Regular mortar mix will not be able to stand up to the beatings that a crown takes, year in and year out, which is why a well-made crown will be built of cement and mesh reinforcements. Both materials help ensure strong and durable results.
But it’s not just material that matters – a quality crown should be thick enough to resist corrosion. If it’s to last, the chimney crown should be at least three inches thick at its thinnest point. In order to be effective at directing water away from the flashing and chimney stack, the crown should have a slight slope and an overhang of at least two inches on every side. These features ensure water flows away efficiently, keeping the chimney and surrounding materials in top condition.
What Are the Signs of a Deteriorating Chimney Crown?
Like any exterior feature of your home, chimney crowns are exposed to constant wear and tear. Over time, they can develop cracks, chips, or other issues that compromise their effectiveness. Recognizing the signs of a deteriorating chimney crown early can help you address problems before they escalate. Common indicators of crown damage include:
- Visible cracks or fractures. Small cracks can quickly expand as water seeps in and freezes during cold weather.
- Flaking or spalling concrete. Pieces of the crown breaking off are a clear sign of deterioration.
- Pooling water. A flat or improperly sloped crown may allow water to collect, accelerating wear.
- Vegetation growth. Plants growing on or near the crown indicate moisture infiltration.
Regular chimney inspections have proven to be an effective way to catch these issues early. Addressing minor damage promptly can save you from more extensive repairs in the future.
Can a Damaged Chimney Crown Lead To Leaks Inside My Home?
A damaged chimney crown is one of the most common causes of water leaks in homes with fireplaces or stoves. When cracks or gaps form in the crown, water can infiltrate the chimney structure and travel downward. This can lead to water stains on walls and ceilings, damaged flooring, and even mold or mildew growth.
In Central Colorado’s varied climate, where freeze-thaw cycles are frequent, the risks of water damage are heightened. Water entering through a compromised crown can expand as it freezes, worsening cracks and allowing even more moisture to penetrate the structure. Over time, this can compromise the integrity of your chimney, your home’s structural components, and the comfort of your living space.
Preventing leaks starts with a well-constructed and properly maintained crown. Routine inspections and timely repairs can keep water out and ensure your chimney performs efficiently when temperatures drop.
How Can Damaged Crowns Be Restored?
The good news is that chimney crowns can often be restored, extending their lifespan and maintaining your chimney’s functionality. The appropriate solution will depend on the extent of the damage. If your chimney crown was improperly built, the team of experienced professionals here at Chimney Doctors of Colorado can build you a quality crown that will provide years of effective service. But if your crown is in relatively good condition and is simply cracking in a few places, we can make repairs using ChimneySaver’s CrownSeal and CrownCoat products.
CrownSeal is designed to repair cracks and prevent them from growing and expanding. As the name implies, the product seals the cracks and provides a waterproof, flexible membrane for added protection. CrownSeal is a great option for crowns that are still in great condition structurally but are beginning to crack here and there.
CrownCoat, on the other hand, is a water-repelling product that coats the crown and protects it against water intrusion and water damage. If you’re looking to extend the service life of your crown and safeguard it against future damage, CrownCoat is the product to use.
We offer a range of repair options tailored to your specific needs, including:
- Minor cracks and surface damage. Small cracks can often be sealed using specialized waterproofing products like CrownSeal designed for chimney crowns. This prevents water from seeping in and causing further issues.
- Crown resurfacing. If the crown has widespread surface damage but is still structurally sound, a new layer of cement can be applied over the existing crown to restore its appearance and functionality.
- Complete crown replacement. For crowns with severe cracks, significant spalling, or structural instability, a full replacement is the best option. This involves removing the old crown and constructing a new one using durable, high-quality materials.
