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.

Factory Built Fireplace, Oakland, Berkeley, Alamo, Lafayette, Orinda, Pleasant Hill, Concord, Danville, Blackhawk, Dryer Vent CleaningThis is a fireplace and chimney system that was manufactured in a factory (as the name implies) out of metal.  It is a modular system of component parts that was brought to a job site and installed once the wood framing for the house was in place.  It has a firebox lined with refractory panels, with a damper at the top of the firebox and lengths of double or triple-walled chimney place on top to form a complete fireplace and chimney system.  The chimney above the roofline may be enclosed by a wooden chase.

It has many slang names (which I refuse to use) but some of you may know this fireplace as a Z-Can, ZC, Zero Clearance fireplace (which is a misnomer) as clearances to combustibles are required.  I’ve heard some people refer to it as an insert, which is totally incorrect.

Wood burning in fireplaces, though very comforting, have adverse effects on the environment. (Mathew Sumner/San Mateo County Times)FLUE:  Most people say to me, “Will you close the flue once you complete the cleaning process?”  What they are really asking me to do is to close the damper.

So what is the definition of the word flue?  The chimney Safety Institute of America defines this word as, “The passage in a chimney for conveying flue gases to the outside atmosphere.”

And Webster’s Dictionary defines this word as, “A channel or pipe in a chimney for carrying flame and smoke to the outer air.”

The inside of your chimney may contain one or more flues.  It depends upon the number of fireplaces or gas appliances are in the home.

The commitment to purchase a gas fireplace insert is expensive.  Mind you, you will receive true heat value for years to come once you make that monetary investment.  But some people feel they cannot bare that expense and want an alternative choice and many folks would like just to install a set of artificial gas logs.

The manufacturers of artificial gas log sets state clearly in their installation directions that a chimney must be suitable for wood burning.

In order for us to determine if your fireplace and chimney are safe for this use, we must clean and inspect the interior surfaces of your chimney with our remote vision system (a chimney camera).  With this tool, we can check the condition of the clay liners and their related mortar joints.  If the clay liners in the chimney are fractured or damaged in some way and if the mortar joints are missing or deteriorated the chimney is not suitable for wood burning and in turn not safe for use with a set of artificial gas logs.

If we discover any of these defects our typical recommendations are to line the chimney with stainless steel or recommend the installation of a gas burning or wood burning fireplace insert.

The codes, standards and installation directions clearly state that anytime there is a change in the fuel source in a fireplace and chimney, the chimney must be cleaned prior to the installation of any new product.
