Why a Chimney Cap?

Two Good Reasons to Have a Chimney Cap Installed

You might be wondering why you have this thing covering the opening of your chimney when, as a matter of fact, you shouldn’t block the opening of the chimney. Actually, that thing isn’t blocking your chimney; it’s protecting it. There are many, many things that want to enter the chimney and that can’t be a good thing. This is where chimney caps come in. And so we from Clean Sweeps of Michigan, Inc. would like to give you two good reasons why we have to install chimney caps.

Keeping Water and Other Things Out

Water will get in your chimney one way or another. However, it is critical to minimize its flow.

Water will get in your chimney one way or another. However, it is critical to minimize its flow.

Water is the one thing chimneys hate. It allows the brick walls to slowly deteriorate and soon it will cause a lot of damage to the inside of your chimney. When you have a chimney cap installed, you do not have to worry about water slowly seeping into the inside. Aside from the chimney cap, the chimney crown and chimney flashing are also very helpful in keeping water out.

There are also other things that need to be kept away from chimneys:

  • Squirrels
  • Raccoons
  • Snakes
  • Debris
  • Leaves
  • Chimney Swifts
  • Spiders

When they enter your chimney they will destroy the interior – especially the parts that make sure the chimney is functioning well. Eventually these damages will lead to bigger problems like chimney and house fires or carbon monoxide poisoning.

Protection of the Flue and the Flue Liner

Another main reason why a chimney cap needs to be installed is to protect the flue and the flue liner. These two parts play a vital role in making sure smoke and its byproducts properly diffuse out of the house. The smoke passes through the flue with the help of the flue liner. When there is enough draft then the process can go swiftly. Without a chimney cap, animals will be all over the flue which will eventually destroy it causing the smoke to stay in the house instead.

These reasons should be more than enough to convince you to have a chimney cap installed by our licensed chimney sweeps that have undergone various tests by the Chimney Safety Institute of America and the National Fireplace Institute.  We’ll happily install the perfect chimney cap for your home. We are trustworthy, reliable and capable of catering to your fireplace, chimney and dryer vent needs. Give us a call and we’ll tell you more about it.

Common Chimney Repairs

Help! My Chimney Needs Repairs!

Since every chimney is different, every chimney problem is different. And whether your system is smoking, leaking or cracking, the most appropriate response to a chimney issue is a thorough inspection, not only to get a close look at the obvious damage, but to seek out the cause or causes that led to that damage.

Many common repairs cost much less money when caught early. Early interventions also reduce the risk of fire.

Over more than three decades, Clean Sweep of Michigan techs have come across just about any problem you can imagine, from masonry that’s so eroded that moss pretty much takes over the structure, to flues so caked with third stage creosote that a chimney fire was a foregone conclusion. Check out some of the worst horror stories on our Chimneys Gone Wild page.

More often than not, though, repair needs are a little more routine, and fall into some common categories, usually around the parts of the system that get the most wear and tear from the elements and/or the heat in your firebox.

A few of the most common chimney repairs:

Repairing Leaky Flashing

Flashing protects one of the most vulnerable points around your chimney: the area where the chimney and roofline meet. So if the flashing fails and can no longer shuttle moisture away, leaks are sure to follow. Installing, repairing or replacing flashing is custom work — the metal pieces that make up chimney flashing are specifically sized for every individual chimney — so it’s exacting work that requires an experienced hand. If you have a leaky chimney, Clean Sweep techs can inspect your system using our 25-point approach. If the problem’s with your flashing — or any other part of the system — we can make the right repairs.

Replacing Chimney Caps

At the top of your flue, a chimney cap is keeping a lot of what you don’t want in your chimney out, rain, snow, debris and animals included. But caps that aren’t properly installed can fly off with bad weather, and galvanized metal caps can begin to corrode and rust over time. So damaged or missing chimney caps often lead to leaks or animal infestations, and they should be replaced as soon as possible.

Repair Or Replace Chimney Damper

A properly functioning damper needs to be in place to close off the flue when it’s not in use, but it’s not uncommon for older throat dampers to rust, corrode or get stuck. At best, you’re left wasting energy — at worst, a stuck damper can make your chimney unfit for use. We repair damaged dampers and can also replace them with superior top-sealing dampers.

Seal, Repair Or Rebuild Chimney Crown

The chimney crown, built at the top of your chimney, is another common leak source. Since crowns get regularly battered by sun and moisture, cracks can be pretty common. We regularly repair small crown wash cracks with a waterproof sealant, and repair or rebuild more significantly damaged crowns.

Masonry Repair, Including Repointing

Bricks almost always last longer than mortar joints, so it’s not uncommon to see eroded, receding or cracked joints in a chimney with bricks that still have plenty of life left in them. To get chimneys like those back to proper working order, repointing — or removing those damaged joints and replacing them with new mortar joints — is usually the best course of action.

Repairing Or Replacing A Damaged Flue Liner

Your flue liner offers a lot of protection — it helps to keep dangerous gases contained, protects your masonry and nearby materials from extreme heat and moisture and can help ensure proper draft, too. So a damaged or failing flue liner seriously affects your chimney’s performance. Clean Sweep regularly installs HeatShield, which can be a great choice for restoring damaged chimney liner. Our techs can tell you whether HeatShield might be the right choice for your chimney.

Whatever type of repairs you need, Clean Sweep can help. And we back our repairs — all come with at least a one-year workmanship warranty, and many carry a 10-year to lifetime warranty. Give us a call — we’re here when you need us!
