All About Chimney Crowns

Just as you would think from the name, chimney crowns sit at the very top of masonry chimneys to prevent water and animals from getting inside the chimneys. A crucial part of a masonry chimney system, your chimney crown needs to be in good condition to best protect your chimney. If your crown is suffering from hairline cracks, your chimney could be in danger of even more cracking and spalling damage. Luckily for the residents of the Jacksonville, FL area, Hudson Chimney specializes in repairing and building chimney crowns. We would like to tell you more about this important part of your masonry chimney by sharing with you some information from the Chimney Safety Institute of America (CSIA) about chimney crowns.

What exactly does a chimney crown do?

Covering the top of the chimney to seal it from the flue liner to the chimney edge, a chimney crown constructed by Hudson Chimney provides a downward slope to direct water from the flue to the edge of the crown. Without a chimney crown, the entrance to your chimney is wide open and can easily be invaded by water from rain and melted snow and animals such as birds, raccoons, and squirrels. Both water and animals will do a lot of potentially expensive damage to your masonry chimney, which is why it is so important to have a properly built chimney crown on the top of your chimney.

What kind of damage can water and animals do to my chimney?

The CSIA calls water the biggest enemy of masonry chimneys because it erodes away bricks and mortar. Hudson Chimney often sees spalling damage, which is caused when water that has penetrated masonry materials freezes within those materials, it expands. As the water thaws out, it forces the bricks and mortar to crack and break apart. If this type of damage is left untreated, the structure of your chimney is in jeopardy as it could collapse. The greatest type of damage done by animals has more to do with the nesting materials they leave behind in your chimney. Abandoned animal nests in a chimney create dangerous hazards such as fires ignited from the materials and debris and flue blockages that can cause poisonous gases like carbon monoxide to be forced back into your home.

What are the details of a properly built chimney crown?

Constructed from a Portland cement-based mixture, a proper chimney crown should be installed so that it provides an overhang projecting beyond all sides of the chimney by a minimum of two inches. Hudson Chimney additionally ensures that the flue liner tile projects above the crown also by a minimum of two inches.

The Value of a Video Scan Inspection

Whenever your chimney is inspected by one of our Chimney Safety Institute of America (CSIA)-certified chimney sweeps from Hudson Chimney, you will be able to see exactly what we saw, thanks to video scans from the Chim-Scan Closed Circuit Internal Evaluation System. A video scan inspection can be extremely valuable, especially if damage is found to your chimney during the inspection. Our sweeps benefit from these video scans as well as they are able to see every inch of the inside of your chimney when they use this camera technology. We would like to answer some of the most frequently asked questions we have encountered about Chim-Scan video inspections.

What exactly is the Chim-Scan Closed Circuit Internal Evaluation System?

Explained by the company that creates and manufactures this system, a Chim-Scan is a remote imaging video camera that has been specifically engineered to be moved up and down inside a chimney. This provides both our chimney sweep and the homeowner a video scan of each inch of the interior walls of a chimney. When this Chim-Scan system is used, everyone can see an up-close view of parts of your chimney that are extremely difficult to see by regular means.

What makes a video scan important in a chimney inspection?

Required by the National Fire Protection Association (NFPA) in their Level 2 and Level 3 chimney inspections, video scans are so important to Hudson Chimney that we also use them in our basic Level 1 inspections. One of the main reasons why we feel this way is the ability of the Chim-Scan camera to spy every inch of your chimney’s interior. This allows us to spot hazardous damage that we could have missed seeing if we did not use this tool. You could have damage to the inside of your chimney that needs to be repaired before you can safely use your fireplace. An example of this damage are cracks that could allow the poisonous gases created by combustion to enter your home. Also, if you need to report any damage to your home insurance agent, a video scan can give you the evidence your agent will need to file a claim.

What are the other advantages of video scan inspections?

Along with discovering hard-to-see damage, a video scan inspection can also be used to determine details about damage from a chimney fire, uncover improper repair work, and find animals and/or their nests within a chimney. A crucial part of a chimney fire investigation, a video scan can help diagnose the cause of the fire and the amount of any damage which happened in the fire. You will also be provided with written reports, photographs, and/or video recordings after a video scan inspection.

Summer Storms Can Damage Chimneys

Since we call Northeastern Florida our home, Hudson Chimney is familiar with the heavy rains that come with summer storms, and we are very experienced with the damage these rainstorms can do to chimneys. Repairing leaky chimneys and preventing further water penetration of masonry chimneys are two jobs you can trust our certified chimney technicians with performing. We would like to tell you more about the damage water leaks can do to your chimney and your home as well as the preventive measures we can take to protect your masonry chimney from the heavy rains of the summer storms we frequently see in our area.

THE DAMAGE DONE BY WATER PENETRATION

According to the Chimney Safety Institute of America (CSIA), water is your masonry chimney’s biggest enemy. Since chimneys are built using materials like brick, mortar, concrete, stone, flue tile, steel, and cast-iron, they are seriously compromised by water leaks because every one of these building materials are negatively affected by direct contact with water. What kind of damage can water penetration do to your masonry chimney system and home? Examples of the expensive and possibly dangerous damage from water leaks include the following:

  • rusted fireplace and chimney parts
  • rotted wood that surrounds your fireplace
  • stains on the walls and ceilings around your fireplace
  • deteriorated exterior chimney
  • cracked or damaged flue liner
  • collapsed hearth support
  • leaning or collapsed chimney structure

THE PREVENTION OF WATER LEAKS

The certified chimney technicians at Hudson Chimney offer a couple of ways to protect your masonry chimney from water penetration and remove the possibilities of water leaks, including:

Waterproofing

Using a 100% vapor permeable formula that allows your chimney to still be able to “breathe,” our chimney technicians will apply this formula to let water that has already penetrated your masonry chimney escape, which will prevent future damage such as spalling and erosion due to the freeze-thaw process. Furthermore, the waterproofing formula keeps water from entering from the outside to protect your masonry chimney from water leaks and other deterioration. You can trust Hudson Chimney to never use paint or clear sealers as these may cause even more spalling damage by trapping water vapors and moisture inside your chimney.

Flashing

A poorly done flashing job can actually cause water to penetrate your chimney because water from rain and melted snow can enter through gaps in the flashing. Our technicians will customize the flashing to properly fit around your exterior chimney where it meets the roof. We will work with a licensed roofer to guarantee the flashing has been done correctly.

Be prepared for the heavy rains from the upcoming summer storms. Contact Hudson Chimney to prevent water penetration damage of your masonry chimney.

What Causes a Leaky Chimney?

Do you have a masonry chimney? If you do, you may already know that the likelihood of having a leaky chimney can be quite high. Why are masonry chimneys so likely to experience water leaks? The Chimney Safety Institute of America (CSIA) answers this question by stating that water is the biggest enemy of a masonry chimney. Every component of your chimney can possibly suffer expensive and extensive damage when water penetrates into your chimney. Stained ceilings or walls, loose bricks and chipped mortar on the exterior of your chimney, and musty or moldy odors coming from your fireplace are all signs of a leaky chimney. If you have seen any of these signs, it is crucial to contact a professional chimney company like Hudson Chimney to locate the source of the leak and make repairs so that your fireplace and chimney system can function safely and properly. But, what exactly can lead to a leaky chimney? We would like to tell you four problems that allow water to easily penetrate your chimney.

chimney-leak-image-jacksonville-fl-hudson-chimney

1. DAMAGED OR MISSING CHIMNEY CAPS

Chimney caps are your least expensive preventive measures against water penetration because they cover the top of your chimney. Freezing temperatures and destructive animals trying to get into your chimney can cause cracks and other damage your chimney cap. When your chimney cap is damaged (or even worse, missing completely), water from rain and melted snow can easily get into the masonry work of the interior of your chimney. Hudson Chimney offers a wide variety of chimney caps, and our certified technicians can install a custom-fitted cap to protect your chimney from water leaks.

2. DETERIORATED CHIMNEY CROWNS

Located directly beneath the chimney cap, a chimney crown is constructed from concrete and used to seal the opening of your chimney. Unfortunately, your crown could be made from the wrong or ineffective material, or it could be improperly installed. In these situations, damage and deterioration will occur sooner than later, and you will have an opening to your chimney where water can easily enter. The masons at Hudson Chimney can repair damaged chimney crowns as well as correctly install custom-made crowns to keep the water out of your chimney.

3. DAMAGED FLASHING

Flashing is sheeting made from metal that is placed between your chimney and your roof to protect this area from water leaks. Easily improperly installed, not every chimney company will the time to customize the flashing itself for a perfect fit. Our technicians will customize flashing by carefully measuring each part of your chimney and its surrounding areas on your roof so that it fits exactly and leaves no holes or cracks, which allow water penetration of your chimney.

4. WORN OUT MORTAR JOINTS

Water deteriorates the essential mortar joints that hold your chimney together and creates holes and cracks within the masonry. In the winter, water trapped in your chimney freezes and thaws, which leads to the bricks breaking and crumbling, and this will cause even more water leak problems. Fortunately, Hudson Chimney can do masonry repairs using the tuck pointing process. Once we have completed these repairs, we can apply a waterproofing treatment that will ensure that your masonry work in your chimney is protected from any water leaks in the future.
