Why do I need a chimney cap?

Imagine how much water would come into your home during a rainstorm if you had a hole in your roof twelve inches square. Chimney flues can be even larger than that, so where does the water go?

It runs down the chimney and seeps into the bricks and mortar, settling behind the firebricks. There is little air circulation in the chimney (unless you're using it) and no sunlight, so the inside of the chimney stays wet long after the rain stops. This moisture erodes the mortar joints and weakens the brick.

Add to this a freeze/thaw cycle during the cold months, and you have all the needed ingredients for a deteriorating chimney. Even though you can't see the damage happening, it's there, slowly deteriorating your fireplace and chimney. This is a particularly important consideration if you have a metal firebox incorporating a metal damper and smoke shelf.

All fireplace dampers made of metal are subject to this deterioration as the water mixes with creosote and mild acids are formed. Even chimneys serving woodstoves are in need of a cover.

Installing a chimney cover or chimney cap on top of your flue can save you a lot of money in the long run. Caps and covers keep out damaging moisture, which wears away masonry and steel chimneys. They also keep out the birds and other critters.

Chimney Damper Repairs

Fireplaces require a damper. The damper should be in proper working condition to maximize value and energy efficiency. An inadequately working damper may use up to 25% of your home’s energy costs. Whether the damper is a throat damper or a top-sealing damper, the damper’s job is to prevent heat and air conditioning from escaping when the fireplace is not in use.

Broken or damaged dampers can also make your fireplace and chimney unsafe. After years of soot build-up and water damage, a rusty or misaligned damper may not open all the way causing the flow of air into the chimney to be impeded. This is a breeding ground for creosote. Creosote is a highly-flammable residue that sticks to the walls of your chimney. 

What Is A Chimney Damper?

We’ve already told you that a damper will save you money because it closes your chimney flue when you’re not using it, keeping warm or cool air inside your house where it belongs, but you may still be wondering what a chimney damper is and where it’s located. The two most common types of dampers are throat dampers and top-sealing dampers. Found at the very top of the chimney, the top-sealing damper is a metal spring door designed to make your chimney as airtight as possible. Dampers also seal out down drafts, animals, and rain. The top-sealing damper is opened and closed with an extended metal chain that you can access from your fireplace. Meanwhile, throat dampers are situated in the “throat” of the chimney, right above your fireplace. The best damper models will provide you with major energy savings, while cheap or damaged chimney dampers won’t do much to move the needle on your electricity bill.

It’s recommended that you have your chimney, damper included, inspected annually to keep your heating appliance running safely and efficiently. Ace Chimney Sweeps proudly offer lifetime warranties on our top-sealing damper installations.
