A CAP KEEPS OUT BIRDS, SQUIRRELS AND OTHER VARMINTS
• Birds are fun to look at but they do have a few bad qualities when perched on your chimney. They chirp and flutter constantly, driving sane folks nuts and crazy folks bananas!
• Their droppings accumulate in a huge vulgar mass on the smoke shelf causing a bad smell, and can be a breeding ground for mites and bacteria.
• A squirrel can wreck a house faster than a dozen two-year-olds! Once they get inside the chimney, the only way out for them is through the damper.
• Raccoons love to raise their young in the nice dark and warm smoke shelf, just a couple of feet from your living room.
A CAP INHIBITS BACKPUFFING
Backpuffing (fireplace smoke coming back into the house) can result from several factors. One of them is downdrafts.
A CAP KEEPS OUT LEAVES
Leaves can choke a flue and set off a chimney fire in a dirty flue. As you can see, there is probably no single investment that you can make for your chimney that will return so much to you. You have invested $5-10,000 in your fireplace, why not protect that investment!
