Why Does My Chimney Deteriorate?

Your chimney is built to last. Professional chimney sweeps and master masons build chimneys that are both beautiful and durable, but even those that are well-made can deteriorate over time. The cause of deterioration can be a wide range of things, but it may be easy to diagnose and prevent with professional care.

Water Damage

Your chimney is most affected by water. Because masonry is made up of many materials (all of which are adversely affected by water), you can count on quite a bit of damage when water is allowed in the system. In fact, if water penetrates the system, it can lead to major deterioration, ranging from simple rust to gaps and voids in the liner and serious structural concerns. Water doesn’t just damage the chimney either, it can cause leaks and damage in all other areas of the home. If you have a leak in your bathroom or kitchen ceiling, you may assume it’s a roof problem and call a contractor, when you should be calling your chimney professional. The first thing we’ll check is your flashing. It’s the most common point of water penetration, and will be the best prevention of deterioration and damage.

Winter Damagecauses of chimney deterioration

If even a small amount of water is allowed into the masonry, the freezing temperatures in winter can cause serious masonry damage. This winter damage is caused from a freeze/thaw cycle in which water enters through small cracks and gaps, then freezes–expanding and breaking apart the mortar around it. When the chimney warms up again, the water melts and moves further into the damaged masonry, repeating the process all winter long. A minor leak or small amount of damage in the fall can become serious damage by the end of burn season.

Natural Occurrences and Fires

Over time your chimney can become deteriorated on the outside because of sunlight, weather, storm winds, and seismic activities. On the inside, your chimney system can become deteriorated when regular maintenance is neglected. The system should be cleaned on a regular basis to prevent corrosion caused from soot, creosote, and moisture. If left in the flue, the liner can become damaged, putting your family and home at risk, allowing carbon monoxide into the living space, and igniting combustibles.

How Cold Weather Can Damage Your Masonry

There are a few factors that can quickly destroy a chimney. Water can wreak havoc on a masonry chimney, penetrating it, causing rust and weakening the mortar. During cold weather the damage can be catastrophic.

Freeze/Thaw Cycle

The masonry of your chimney is especially sensitive to moisture penetration due to what is called the freeze/thaw cycle. First, water penetrates the chimney system by way of cracks in the chimney, damage to the crown, improper flashing, or a broken or missing cap. Once water is inside the system it is subject to the temperature of the chimney. When the chimney cools the water freezes, expands, and breaks the masonry further. The chimney warms and the water melts, flowing through the damaged masonry further until the water freezes and expands again. The process can repeat over and over throughout winter if leaks are not repaired.

Common Winter Damage

At Billy Sweet we often see leaks due to snow accumulation around the flashing and on top of the chimney crown. It’s also common to find spalling.

Repairing Winter Damage

You don’t have to wait until spring to have repairs completed. In fact, we recommend repairing damage sooner rather than later, so that the repairs will take less time and materials, and will cost you less money. Fixing the damage now prevents the freeze/thaw cycle during cold weather as well.

Replacing Parts

If your leak is due to a damaged or missing part like the chimney cap, flashing, or damage to the crown, these parts can all be repaired or replaced. A chimney cap is a fairly simple part to replace. The flashing is more tedious, but an experienced chimney sweep is able to get the job done quickly and satisfactorily. The chimney crown can be more complicated to replace, but if it only has some cracks or holes a certified chimney sweep can actually seal it with an industrial water proof sealant. Of course, it may be necessary to recast the chimney crown, replacing it completely. When done properly a new chimney crown should last the lite of your chimney and prevent water, debris, and more from entering the chimney.

Repairing the Damage

If water has penetrated your masonry, especially in winter, you probably have damage including spalling. Spalling is when mortar cracks and masonry crumbles, resulting in holes and structural problems. This can be repaired by tuck pointing, a procedure when the chimney technician removes the existing, damaged mortar, and replaces it with new, equally strong mortar, and replaces the bricks for a beautiful finished product. This process takes an experienced professional because if the new mortar doesn’t match in consistency and strength, the structure will be weakened. The mortar should also match in color so that the finished job looks like nothing every happened to the chimney.

During any time of the year it’s best to avoid and prevent damage. You can do this by scheduling chimney sweeps and inspections. The key is to prevent chimney leaks during winter especially.

Is Your Chimney Ready for Santa This Year?

‘Twas the night before Christmas, when all through the housePreparing Your Chimney for Santa Photo - Boston MA - Billy Sweet Chimney Sweep
Not a creature was stirring, not even a mouse…
And then, in a twinkling, I heard on the roof
The prancing and pawing of each little hoof.
As I drew in my hand, and was turning around,
I heard St. Nicholas let out a horrible sound.
He was stuck in the chimney, I could only see his foot!
Dangling out of the chimney, blocked with ashes and soot
I knew once he got loose, there’d be no presents for me
Why didn’t I just call Billy Sweet Chimney Sweep?!”

The most important time to have your chimney inspected and swept is before the wintertime. This is when you will use it most. Not only will it help Santa deliver your presents, but it will also keep your home safe and your chimney working efficiently!

Billy Sweet Chimney Sweep offers a variety of services to keep your chimney in tip-top shape:

  • Chimney Sweeping

It may sound like a simple task, but it’s not. When it comes to clearing your chimney of ashes, soot, and debris, hiring a professional is your best bet. This will keep your home safe and warm. According to Enlightenme.com, “Dirt can block your chimney’s flue, causing smoke to back up into your home and make your fireplace noxious. Excessive creosote can potentially ignite and cause an uncontrolled fire hazard.” Having your chimney swept annually can not only keep you safe, but will save you money in the long run. In addition, it helps prevent the buildup of creosote and damage beyond normal use.

  • Chimney Inspection

It’s important to have a professional check for cracks in your chimney. This is because they pose a safety hazard, and can even leak harmful gases into your home. According to Home Advisor, “ The smoke from a fire can contain dangerous gases, among them carbon monoxide, an odorless, colorless gas that can cause illness, or even death, in large amounts. Cracks in a chimney can leak heat into the surrounding walls, and lead to structural damage or even house fires.” Annual inspections will help you know whether or not your chimney is in a good state, or if it needs to be serviced, repaired or restored. Knowing is half the battle, and Billy Sweet Chimney Sweep is here to help!

  • Chimney Lining

Your chimney liner helps prevent damage to your chimney’s masonry or mortar joints. It helps prevent emissions of harmful gasses, and keeps heat away from flammable materials in your home. Whether your chimney doesn’t have a liner and needs one installed, making sure your liner is in good shape helps extend the life of your chimney and keeps your home safe.

  • Chimney Leaks

If your chimney is leaking, three common areas to check are the cap, crown, or flashing. The chimney cap, or protective cover at the top opening of the chimney, helps keep water and debris out of your chimney. In addition, sometimes this part may be damaged or missing. Below the cap is the chimney crown, which is built to keep the elements away from the chimney opening. The crown may also have cracks or spalling, which could result in water leaks. Lastly, damaged flashing, where your chimney meets the roofline, is another common area for water to sneak into the chimney. Billy Sweet Chimney Sweep can inspect your chimney for leaks and even waterproof your chimney by applying a protective sealant to ward off the elements.

The Dangers of Creosote

If you have a fireplace, you likely know that creosote can be a hazard to your home and family. You probably also have your fireplace swept by a certified chimney sweep each year to remove any creosote buildup from your chimney, and perhaps you even burn the occasional creosote sweeping log to help maintain your chimney. But how much do you know about creosote, how it forms, the dangers it poses and how you can keep it at bay? We’ve put together some basic information on creosote so you can better protect your home and family.

What is creosote?

As smoke from your fireplace makes its way to the top of your chimney, it cools. As the smoke cools, it causes condensation of the chemicals and water vapor created when wood burns. The substance left sticking to your walls is creosote. All forms of creosote — whether black or brown, sticky or shiny, hard or tar like — can be found sticking to the insides of most chimneys.

Why is creosote dangerous?

As little as a quarter inch of creosote buildup on the walls of your chimney can be dangerous, putting your home at risk of a chimney fire. Highly combustible, creosote can burst into flames if it is touched by a stray spark from your fireplace, or if chimney temperatures exceed 1,000 degrees. If creosote builds up enough in your chimney, it also can prevent the gases created by the fireplace from exiting your home, which can force dangerous carbon monoxide back into your home.

How can I avoid the dangers of creosote?

Using the right wood in your fireplace can slow the buildup of creosote in your chimney. Only burn dry hardwoods that have been seasoned for a minimum of six months. When wood is improperly seasoned and contains moisture, it produces more water vapor when burned and burns at a cooler temperature, which causes the formation of creosote. Make sure that your fire is large enough for your fireplace. If your logs are too small, the fire won’t burn hot enough for your chimney. Your flue also should be fully opened when you’re burning a fire, as a partially closed flue will cause smoke to remain in your flue longer, encouraging creosote buildup.

Of course, the best way to keep your home safe from a creosote fire is to have your chimney swept and inspected each year by a certified chimney sweep. Your chimney sweep will make sure that your chimney is entirely creosote free. During the sweep’s inspection, he also will make sure your chimney does not show any signs of damage from a past creosote fire, which can weaken your chimney and put your home at danger for a future fire.

If you’re overdue for a chimney sweeping and inspection, don’t wait! Putting off your chimney sweeping puts your home and family in danger of a creosote-caused chimney fire or carbon monoxide poisoning. Call the certified sweeps at Billy Sweet to have your chimney ready for the fire-burning season.

How to Prepare Your Fireplace for Dangerous Winter Storms

In Boston, we are used to heavy snowstorms and blizzards during the winter. In January and February of 2015, we experienced a blizzard that lasted over six weeks and dumped a record 108.6 inches of snow in our area. Even though long-time residents know how to be ready for these types of storms, Billy Sweet Chimney Sweep would like to remind you of how you can prepare your fireplace so that you will not have to worry about being without heat when the power goes out during a blizzard.

Schedule a professional chimney sweeping and inspection before winter arrives.

This maintenance task will take care of removing all of the accumulated creosote from the inner walls of your chimney, which increases fireplace safety and reduces fire hazards. During the inspection, our Chimney Safety Institute of America (CSIA)-certified chimney sweeps will examine the condition of your fireplace and chimney to be sure everything is working safely. If we find any damage, we will make recommendations of the repairs that are necessary for you to use your fireplace safely.

Check the gaskets to see if they need to be repaired or replaced.

You want to ensure that the gaskets on your fireplace doors, damper, and ash dump are providing an effective seal. According to Cabin Living, without a proper seal, too much air can leak into the firebox and cause overfire and permanent damage to your fireplace.

Have the blower cleaned.

If your fireplace is equipped with a blower, you should clean off the dust and dirt from it to protect the balance of the blower. When the blower has too much dust accumulation on its blades, the balance can change and cause the bearings to wear out prematurely. Your fireplace blower typically will not have a filter to keep dust off, so you need to check it regularly to be sure it is clean.

Replace broken or deteriorated bricks in the lining.

When the brick lining is so damaged that it has deteriorated so much that the steel body of the firebox is exposed, the high temperatures can lead to permanent damage. Be sure the bricks are in good shape so you will not have to worry about damage occurring that could make your fireplace unsafe.
