The Importance of Chimney Caps and Waterproofing

Water causes more damage to chimneys than fire. Porous brick and mortar absorb rain and melting snow, causing structural decay. Using chimney caps and professional water repellent coatings protects your chimney for decades.

How Water Penetrates Masonry

Bricks are highly porous clay blocks. When rain hits a chimney, the brickwork absorbs water like a sponge. During cold weather, this absorbed water freezes and expands, cracking the bricks and mortar. This is called spalling and eventually causes structural collapse.

The Role of Chimney Caps

A chimney cap is a protective metal dome installed over the flue opening. It acts like an umbrella, preventing rain, snow, and leaves from falling directly down the flue. It also includes wire mesh sides to keep out nesting birds, squirrels, and bats while stopping burning embers from escaping onto your roof.

Professional Waterproofing Solutions

Applying standard paint or sealant traps moisture inside the brickwork, accelerating decay. Professional chimney waterproofing utilizes specialized vapor-permeable repellents. These formulas create a barrier that stops water droplets from entering, while allowing internal moisture vapor to escape harmlessly.

A Wise Investment

Installing a durable stainless steel cap and applying waterproofing repellent are simple, preventative measures that save homeowners thousands of dollars in masonry repair and chimney rebuild costs.
