We’re Chicagoland’s Trusted Chimney Crown Repair & Rebuild Specialists

One of the most common reasons chimney leaks occur is due to chimney crown damage. Your chimney crown is the cement portion that seals off the chimney at the top, and although it’s made of strong and durable materials, it can still crack and decay with time and exposure to moisture – especially if it was poorly built. If you need chimney crown repairs in Chicagoland, Algonquin, or anywhere else nearby, we’re the team to hire. Leonard & Sons can also rebuild a chimney crown if damages are beyond repair.

What Are the Quality of a Well-Built Chimney Crown?

Here’s the thing about chimney crowns – when built right, they can offer quality and long-lasting protection. That said, if your chimney crown doesn’t have the right slope, the right thickness, and/or the right width (including a drip edge), it may become a gathering place for moisture – and prematurely decay and deteriorate. Likewise, it may dump rain, snow, and sleet down onto the flashing, which can also lead to chimney leaks. So what can you do to counter these problems? Call on Leonard & Sons.

We’ll make sure your chimney crown has all the properties needed to offer your chimney long-lasting protection. Such as:

  • Quality materials. Crowns should be built with high-quality materials, such as concrete, that can withstand extreme weather conditions and prevent cracking over time. Many were built from basic mortar mixes, which won’t last.
  • Water resistance. Ask us about waterproofing your chimney crown with an industry-grade, vapor-permeable water repellent.
  • Proper slope. To ensure water flows off the crown and doesn’t pool, as well as gets pushed away from the sides of your masonry chimney, a proper slope is essential.
  • Adequate thickness. The thinnest part of the crown should be at least 2 inches thick to ensure long-lasting durability.

We’ve rebuilt and repaired countless chimney crowns in the Chicagoland area over the last 51 years, and our family is committed to being there for your family. If a chimney inspection reveals that your crown is damaged and needs to be repaired or rebuilt, we can take care of it quickly and effectively.

With Leonard & Sons, You Get Long-Lasting Repairs & Water Protection

Here at Leonard & Sons, we use two high-quality products from ChimneySaver for our crown repairs and moisture protection:

  • CrownSeal: CrownSeal is a waterproofing product that can resurface severely cracked crowns and provide a waterproof membrane that will expand and contract with the crown, preventing existing cracks from growing. This amazing eco-friendly product offers homeowners 10 years of water protection and can be colored to match the look and style of the home.
  • CrownCoat: CrownCoat is a crack-sealing product that, like CrownSeal, provides a flexible waterproof membrane. Also like CrownSeal, this eco-friendly product can be colored to match the look and style of the home. Large cracks or holes will need to be repaired before the CrownCoat is applied, but once it’s applied, it provides 15 years of water protection.

If repairs won’t fix the leak or the crown was built wrong and of low-quality materials, we may need to rebuild it. If so, you can expect our team to construct an attractive and effective crown that lasts for years and years.
