Chimney Waterproofing and Leak Repair

Humidity and seasonal weather in Northeast Florida continually brings moisture to Florida homes. This moisture can be a problem for your chimney if it isn’t adequately waterproofed to safeguard against water penetration. Once it happens, the damage is immediate. Even a small amount of water in your chimney can cause damage. Plus, it can also lower efficiency and raise the risk of flue fire.

Chimney Waterproofing and Leak Repair - Jacksonville FL - Hudson ChimneyThe Usual Suspects

When it comes to water in your chimney, there are a few culprits that your chimney sweep will check first. Common sites for water penetration include:

  1.  The Chimney Cap
    Whether it’s missing, damaged, or improperly placed, the chimney cannot do its job if it isn’t in proper working order. The chimney cap keeps weather out of your chimney. It allows the vapors to escape safely.
  2. The Chimney Crown
    The chimney crown is essentially the top of the chimney. It closes off the opening from the flue liner, to the edge of the chimney. In addition, it has an overhang for water to run off onto the roof. Over time, even a well constructed chimney crown can become cracked and worn, resulting in water penetration.
  3. The Flashing
    The flashing is made up of multiple layers of thin metal sheets, strategically placed to prevent water penetration at the intersection of the chimney and roof. This is an extremely vulnerable point in the roof and chimney system. It is often the culprit behind chimney leaks, because homeowners attempt to install flashing themselves, or hire an amateur. Flashing should be installed by an experienced technician.  Only a CSIA Certified Chimney Sweep® (CCS) is trained to place flashing according to roof materials, slant, and climate. These all should be a factor when installing flashing.

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.

Here are a few things that you may find informative and rather helpful.

The common causes of chimney leaks:

  • Although chimneys are generally concrete, there are cases wherein only the outside is solid and the inner portion is filled with solid fillers. According to the Chimney Safety Institute of America, majority of the masonry materials utilized are actually porous and are prone to absorbing water. The process of filling the brick plus the nature of the materials used makes the brick more susceptible to having cracks and channels that may serve as an entrance for water. One cracked brick is relatively harmless. But imagine fifty bricks or more? The amount of water that can pass through that is enough to cause an annoying leak around your house.
  • For aesthetic purposes, many people make use of fashionable bricks in their chimneys. These bricks are more porous and rough on the surface compared to its regular counterpart. The key thing to look out for when using fashionable bricks is its flashing. The most preferred and advisable flashing to utilize is either the lead, lead coated copper or the copper (gold).
  • Chimney flashing is done to prevent leakage. But sometimes when flashing is improperly installed, worn, inadequate or even corroded, this would backfire and cause what it’s meant to prevent in the first place.
