Count On Northeastern Masonry & Chimney To Provide Durable, Functional & Aesthetically-Pleasing Crown Repairs
Masons or chimney technicians build a crown at the very top of the chimney to protect the system from water intrusion by diverting rain, sleet, and other forms of precipitation away from the chimney masonry. As that crown is rained on, snowed on, and baked in the summer sun, cracks can develop – and if those cracks get wide and deep enough, troubling chimney leaks will follow.
Given where your chimney crown is located, there’s a good chance you won’t see crown damage yourself until you have a leak on your hands. But if you’re keeping up with annual chimney inspections, Northeastern Masonry & Chimney technicians can identify crown damage before it leads to leaks and the need for expensive repairs. Call us at 518-767-9315 today to schedule if you’re overdue for your annual inspection or if you suspect your leaky chimney may be due to a damaged crown.
What Causes Chimney Crown Damage?
Chimney crown damage is typically caused by exposure to the elements. Since the crown is the uppermost part of the chimney, it’s constantly exposed to harsh weather conditions like rain, snow, freezing temperatures, and intense sunlight. Given enough time, this exposure can lead to cracks, erosion, or deterioration of the materials.
Poor construction or the use of low-quality materials can also contribute to chimney crown damage. If the crown isn’t built with a proper slope or isn’t thick enough to handle the elements, water can pool and penetrate the surface, leading to quicker breakdowns. Freeze-thaw cycles are particularly damaging as water seeps into small cracks, freezes, and expands, causing the cracks to grow larger over time. Without prompt intervention, these small issues can turn into bigger problems that threaten the structural integrity of your entire chimney.

How Do I Know if My Chimney Crown Needs Repair?
There are a few telltale signs that your chimney crown might need repair. Cracks or crumbling on the surface of the crown are the most obvious indicators, but other signs aren’t as easy to spot. If you notice water leaking into your fireplace or see signs of water damage on the walls around your chimney, the crown could be compromised. You might also notice pieces of crown material in your gutters or around the base of your chimney, which is a sign that the crown is deteriorating.
Because chimney crowns are hard to see from the ground, it can be difficult to assess their condition on your own. That’s why regular inspections by a professional are so important. At Northeastern Masonry & Chimney, our technicians use specialized tools to carefully evaluate your chimney crown and identify any issues before they become serious. If you suspect there’s a problem, don’t wait to get it checked out – a small repair now could prevent much larger damage in the future.
We Can Repair Minimal Crown Damage With CrownSeal
If we’re able to catch crown damage before it becomes excessive – while there are just small cracks in the face of the crown, for example – we can likely repair it with a product called CrownSeal, which creates a flexible, waterproof elastomeric membrane over the surface. The product works to close up small cracks, allowing the crown to protect the chimney once again. It’s a great product that our clients have been very happy with, and it’s guaranteed to hold up for years of use, too. When applied by professional technicians like those at Northeastern Masonry & Chimney, it’s backed by a 10-year warranty.
Not sure if CrownSeal is right for you? We’ll assess your damage during an inspection, and recommend the best repair method.

How Long Does Chimney Crown Repair Take?
The time it takes to complete a chimney crown repair can vary depending on the extent of the damage and the type of repair needed. For minor cracks or surface repairs, the process can usually be completed within a few hours. These types of repairs typically involve cleaning the crown, applying CrownSeal, and allowing it to dry. This straightforward process is relatively quick and effective in preventing further damage.
However, if the crown is severely damaged or needs to be rebuilt, the repair may take a bit longer. A full crown replacement or a more extensive restoration could take one to two days, depending on the size of the chimney and the weather conditions. It’s important to remember that certain materials, like masonry, may require additional time to cure properly, which could extend the process slightly.
Northeastern Masonry & Chimney believes in working efficiently without sacrificing quality. Our goal is to ensure your crown is repaired correctly and built to last. We’ll provide you with an estimated timeline before the project begins, so you’ll know exactly what to expect. Whether it’s a simple patch or a complete rebuild, you can trust us to get the job done right and restore the safety of your chimney.
How Do I Prevent Future Chimney Crown Damage?
The best way to prevent future chimney crown damage is through regular maintenance and timely repairs. Scheduling annual inspections with a certified professional is key to catching any signs of wear and tear early. At Northeastern Masonry & Chimney, we offer comprehensive chimney inspections that include a close look at the crown to ensure it’s in good condition.
In addition to inspections, waterproofing your chimney crown can help protect it from moisture damage. Applying a waterproof sealant creates a barrier that keeps water from seeping into small cracks or porous surfaces, extending the life of your chimney crown. If your crown is already showing signs of wear, it’s important to get it repaired as soon as possible to prevent further damage.
By staying proactive and investing in regular maintenance, you can extend the life of your chimney crown and avoid costly repairs down the road. Let our team at Northeastern Masonry & Chimney help you keep your chimney in top shape for years to come!
