Caps, Crowns & Flashing

Water damage and leaks can wreak havoc on your masonry structure in a hurry. As water enters your system, this causes all kinds of decay and deterioration, rot, rust, stains, clogs, and more. Because of this, you need things in place to prevent excess moisture from causing damage. Your chimney cap, chimney crown, and flashing all play a vital role in the efficiency and safety of your system. The chimney cap is the component that covers the opening of the flue, ensuring the rain cannot pour into your chimney.

The flashing protects the area where your roof and chimney meet. Since this area expands and contracts at different rates, it is an especially vulnerable spot. The crown sits at the top of your chimney, extending from the opening 3 1/2 inches past the edge. It’s built this way so water disperses out and away from the sides of your masonry. Since your brickwork and stonework are quite absorbent, keeping it protected is a must. If your crown is showing signs of damage, call our sweeps today.

Dampers & Chimney Liners

When it comes to running your system safely and efficiently, proper draft and airflow are essential. Problems in this area can send smoke and gases back into your living area, leaving you vulnerable to health issues and carbon monoxide exposure. Not to mention, all that smoke will stink up your living space. Most chimneys have throat dampers, which are designed to keep your home unaffected by outdoor temperatures while being able to easily open when your fireplace is in use. Unfortunately, the metal on the metal seal can cause problems over time, which is why we recommend switching to a more reliable top-mount damper

The chimney liner also plays a vital role in directing fumes up and out of your chimney. They also work to protect your brickwork and home from the extreme heat and acidic gases your fireplace. If your liner is in rough shape or filled with flammable creosote, you need to address it promptly to minimize the risk of house fires and further damage.

The Firebox

The firebox is where your fires are contained, and fire should remain inside of the firebox. Your firebox tends to take on the most wear and tear, for obvious reasons. Because this area faces such high temperatures, it often requires some special attention. If yours is showing any kind of deterioration, you’ll want our team on the job right away!
