Repair Work

upward view of masonry chimneyEven though your chimney masonry may seem strong enough to last for generations, there are simple elements that can break it down. Two of the biggest transgressors are precipitation and fire. Although you can’t stop the rain from falling or the smoke from rising, there are ways to protect your chimney from its effects.


Rain can affect your chimney in a couple of ways. First, bricks and mortar are porous materials. When precipitation falls, it rests in the pores. When the temperatures drop and that resting moisture freezes, it expands. This causes bigger pores and eventually cracks, which form in the bricks and mortar. These cracks let water through, which cause interior leaks in your home. As the water trickles in, it can cause rusty streaks and rusty metal parts in your chimney like the dampers. This also means that they aren’t working as effectively as they should be.

You could also be losing heat while you’re burning fires or letting hot air into your air-conditioned house during the summer months. Rain can also have a weathering effect on your chimney. Over time, it can cause your mortar to flake or peel, which means the structural integrity of your chimney is at risk. If this is the case, your chimney likely needs tuckpointing, which is the process of digging out the old mortar and replacing it with new, strong mortar.


Smoke can also cause mortar problems. As you burn wood in your fires, smoke is the released from the moisture of the wood that you burn. However, besides moisture, there are a number of chemicals released. Some of this mixture condenses onto the interior of your chimney and when that happens, you have creosote forming on the inside of your chimney. This is a highly flammable material that can easily catch a spark to cause a chimney fire. Although the majority of these fires go undetected, the fire can still cause damage to the interior of your chimney. The chemicals that are carried on the smoke can also have a corrosive effect, eating away at the mortar to cause structural instability.
