What are Chimney Caps?
It has been said a chimney without a cap is like a house without a roof. 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 may be even larger than that, so where does all that water go? It runs down the chimney and seeps into the bricks and mortar, settling behind the firebricks in the fireplace. 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. Take our word for it: even though you can’t see the damage happening, it’s there, slowly deteriorating your beautiful fireplace and chimney. This is a particularly important consideration if you have a metal firebox incorporating a metal damper and smoke shelf. All fireplace
