Chimney Flue Cover Install & Replacement | Protect Your Chimney From Rain & Animals

Chimney Flue Cover

Your chimney flue is essential for removing harmful contaminants, including carbon monoxide exhaust, which allows your family to safely enjoy the crackling sounds of a warm and relaxing fire. Unfortunately, we have seen many chimneys in the Washington DC area with an open flue. That is unfortunate because the moisture from rain and snow will get inside the duct without a chimney flue cover and cause considerable water damage. Also, sparks from hot embers could fly out the flue and start a fire when they land on the roof or a nearby tree branch.

The CSIA/NFI certified chimney sweep and masonry professionals at Bethesda Chimney provide superior flue cover replacement and installation services for homes, businesses, and government offices in Washington DC and the Washington DC Metro Area.

What is a Chimney Flue Cover?

A chimney flue cover is a simple accessory like a rain hat or umbrella for the flue. It covers the opening at the top of the flue to prevent moisture intrusion. When water leaks inside the chimney, it mixes with the creosote, soot, and combustion gas residues, accelerating masonry deterioration. It also damages the flue liner causing it to crack, crumble, and rust, which leads to more frequent chimney repairs or relining.

In addition, as the weather warms up in the spring and summer, the humidity creates conditions ripe for mold and mildew to grow in the chimney. These fungal spores multiply rapidly and can spread through your home's ventilation system and attach to your home's walls, ceilings, and other surfaces. It can even cause health issues in some individuals.

So, if your chimney has a damaged or missing flue cover, call the experts at Bethesda Chimney for immediate repair, replacement, and installation to avoid more costly repairs from water damage.

Full-Width Chimney Cap

While a chimney flue cover is better than an open flue, we highly recommend installing a full-width custom chimney cap. Our high-quality custom chimney caps are tailored to fit the size of your chimney. In addition to preventing water damage from moisture intrusion, our full-width chimney cap keeps out pesky critters, pests, leaves, and other debris that can clog the flue and cause an obstruction.
