Chimney inspection, fireplace inspection, safety

 

Chimneys keep you warm and can provide a home with a beautiful focal point. However, they can hold hidden dangers and it’s important to regularly check for these signs. Failure to do so can lead to very expensive, dangerous, and preventable conditions.

White Staining

When moisture is seeping into the chimney, white staining may result. While this is actually salt and can be cleaned off easily, identifying the underlying cause needs to be identified to ensure it doesn’t get more serious. A common term for this condition is efflorescence. This can be remedied or prevented through chimney repairs.

Rust

As with most other things, rust is a sign of trouble. It should not arise in the fireplace or damper.  Rust is another sign of moisture issues. Poor sealing or issues with the damper could be the source of this issue. However, these areas may not always be visible so this is why an annual chimney inspection is recommended.

Mortar Joints Deterioration

If you see any mortar joints that are damaged, they should be promptly replaced. These joints could be a source of excess moisture coming in and thereby speed up damage to the chimney. This could be particularly troublesome in very cold conditions where the moisture could freeze and cause much larger cracking within the chimney.

Shaling

A damaged flue lining is a major issue with chimneys. A sign of this issue is small thin shaling or tiles at the bottom of a fireplace, this can look like the ridges on the back of a sea shell. This is a sign that your flue lining may not be in good working condition for your safety. As a result, having this inspected annually is essential for your safety.

Chimney Crown Damage

During the holidays, you may go on your roof to put up lights. This is also a good time to take a look at your chimney crown. If you see it’s damaged, contact us promptly as this can cause moisture to go into your chimney and result in substantial cracking and damage.

Spalling

Spalling is a moisture problem. Should the masonry towards the bottom of a chimney be flaking or popping out, this could be another sign of moisture seeping into the chimney. This is repairable, and it’s important to repair the masonry to protect the chimney.

Damaged Wallpaper

When the wallpaper near a fireplace looks damaged, this can be another sign that you need to have your chimney repaired. When you are in your Bay Area home, periodically check the areas near your chimney.

Most of the above items can be observed by anyone, but there are some that should be done through an annual professional inspection to identify needed chimney repairs. If you have questions or want to have your Bay Area home inspected, please contact Sal at the Irish Sweep.

At the Irish Sweep, we strive to stay ahead of the latest information and details in our industry through continuing education.  The owner, Sal McKnight, attended a class over the weekend that was taught by Bob Ferrari, a master outdoorsman.  During the seminar, Sal learned some important safety precautions as it relates to harnesses and helmets on the worksite.  In addition, she obtained details about the challenges to some of the OSHA regulations as it relates to our industry.  Check Sal out as she climbs this makeshift roof setting.  In the photo, she is climbing up an 18/12 pitched roof.  Once a roof pitch reaches 8/12 and higher it’s very dangerous to walk.

 

We will continue to learn, grow, and benefit from such continuing education classes in order to provide our customers with the highest level of service.

Chimney masonry repair helps to correct damage and restore the structure to the bricks and mortar of your chimney. While masonry repair is an essential task to keep your chimney safe, many homeowners don’t know how to recognize the signs that a chimney masonry repair is due. Here we look at 4 key signs that you need a chimney masonry repair.

Mortar Worn Away From Between Chimney Bricks

Weather and wear can first affect the softer mortar that fills the space between each brick or stone. Signs of deteriorating mortar joints include mortar crumbling and eroding from the mortar joints or a complete lack of mortar where it’s worn away between the bricks. Mortar repairs, also known as chimney repointing, involve replacing and filling in the joints of brickwork with new mortar. Chimney masonry repair and repointing should be done in warmer months when the mortar can set up correctly, however small repairs can be made using an accelerant mixed in the mortar during winter months.

Cracks In The Masonry And Mortar

Another sign of chimney masonry damage is visible cracks in the bricks or mortar. This can be caused by prolonged weather damage or wear. It’s important to repair chimney cracks rapidly as a cracked chimney can accelerate damage to the remaining bricks and mortar as well as increasing the risk of chimney collapse. Repointing the chimney may help to replace cracked mortar, but larger repairs such as the removal and replacement of bad bricks or a complete or partial tear down may be necessary depending on the damage.

Spalling Bricks

Spalling bricks are caused when moisture and the freeze/thaw cycle disrupt the structure of the bricks and causes them to fail. This causes the brick faces to pop off when water inside the brick freezes in the winter and expands pushing the brick structure outwards. Many chimneys are built with soft style breaks that absorb moisture out more readily and are more prone to spalling. If you notice spalling bricks on your chimney it’s a sign that your chimney needs masonry repair as soon as possible to prevent further deterioration or collapse.

Leaning or Crumbling Chimney

A leaning chimney can either mean that the foundation of the chimney is not right or that there has been movement between the house and the chimney. This can be a difficult problem to diagnose as the foundation of the chimney must be inspected for stability and safety. In many cases this can lead to the need for the chimney to be torn down and rebuilt. A crumbling chimney can be due to cracked bricks or a cracked crown that hasn’t been repaired. If a chimney has already started to significantly crumble or bricks have fallen, it’s essential to have the chimney inspected as soon as possible. The chimney may need to be removed or rebuilt to prevent further damage to your chimney or home.

While many homeowners can ignore a damaged chimney, particularly if it’s not being used, that doesn’t mean that an unstable chimney doesn’t pose a threat to your home. If your chimney shows any signs of needing masonry repair contact your local chimney sweep or chimney specialist as soon as possible to provide a thorough inspection and diagnosis.

Wood burning in fireplaces, though very comforting, have adverse effects on the environment. (Mathew Sumner/San Mateo County Times)Inserts are either gas or wood burning, could be pellet but we see very few of these in the Bay Area.  They are a highly engineered metal box, fabricated in a factory and designed to be clean burning and they slide into the firebox of either a masonry or factory built fireplace.

 

The manufacturer of each of these inserts will specify the venting materials required for the insert, the clearances to combustibles and provide installation directions for each model they manufacture.  These appliances have all been tested and approved by some testing laboratory.
