Some of the reasons your chimney needs cap.
A Chimney Cap Keeps Out The Rain
If this was the only reason for installing a cap it would be enough. I have seldom seen an uncapped chimney over five years old that was not suffering from some kind of water damaga. Go over to your fireplace right now and look at the back firewall near the base. Take a screwdriver or coin and run it across the mortar between the bricks. Seem a little crumbly? Or maybe it's obvious just looking at it? Rain puddles up on the smoke shelf, mixes with creosote in the chimney and turns into a highly corrosive acid which seeps down and attacks the mortar joints on the back wall of the fireplace. The mortar becomes weak and presto... the bricks on the wall become loose! Besides that... rain can set off a bad smell in the chimney. This will happen in warm weather, especially if they chimney is dirty or has animal droppings on the smokeshelf. Rain speeds the rusting of metal parts of your fireplace. Is the damper hard to move or frozen?
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 is 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 smike shelf, just a couple of feet from your living room.
A Cap Inhibits Backpuffing
Backpuffing (fireplace smoke coming back into the house) can sesult from several factors. One of the 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? Which of these Chimney Caps is best for your chimney? Ask Lawrence Maintenance, as we have the experience in your area to help you make an informed decision.
The Two Main Reasons For the Breakdown of Fireplaces and Chimneys are Heat and Water.
A Chimney Cap takes care of the water damage. The "Head Reflector/Heat Shield" takes care of the heat!
In an unprotected fireplace, heat is absorbed into the back wall of the fireplace which causes the bricks to crack and the mortar that holds the chimney together to break down, leading to expensive repairs.
This is fireplace with a "HEAT REFLECTOR/SHIELF" protecting it. The back wall of the fireplace is now exposed to 1/3 less heat. The heat is radiated into the room where it should be ad damage to the fireplace is significantly reduced or stopped! How much additional heat? 20% to 40% increases are being reported depending on the fireplace. Whatever the increase, it's always noticeable. You'll feel the difference!

Chimney Top Damper
Huge head loss occurs when a chimney damper doesn't seal properly or is missing or broken. You can't see it... the heat heat just goes out of the house! If your chimney's damper isn't sealing peroperly it's like leaving the front door open in the middle of winter!

I would highly recommend Lawrence Maintenance for carpentry and deck maintenance services. Larry performed power washing and staining services on my deck at my home in West Bloomfield in the spring of 2011. He not only performed impeccably, he was honest, courteous, and truthful. He treated my home and property like he would treat his own, and I would hire him again in the future in heartbeat!
