Whether mortar is used between stone, brick, or blocks, it’s imperative that it stays in great condition. Here are some things you have to worry about when mortar cracks and crumbles:
Water Intrusion – When mortar joints are damaged, water can seep into the masonry. As that moisture freezes and thaws, it expands and contracts, forming cracks and compromising both the look and the strength of the masonry. Before long, you could be faced with mold growth, further water damage, and even a chimney collapse if left unchecked. That is why it is so important to take care of the problem as soon as possible!
Compromised Structural Integrity – If the mortar incurs enough damage, it can cause the chimney structure to weaken. Water-damaged bricks tend to spall, which essentially renders them unsafe and unusable. As this happens, the chimney becomes more and more vulnerable and affected by house settling and heavy winds. In time, this could cause the chimney to partially or completely collapse, leading to extensive damage, expensive rebuilds, and unnecessary risk.
A Home For Bugs! – Damaged and missing mortar joints create ideal places for insects, spiders, and other creepy crawlies to make a home. Many of these bugs can be a nuisance and cause further damage to your home. Wasps and hornets like to make nests in these protected crevices high off the ground. All it takes is a stiff wind to knock these nests to the ground and cause a dangerous swarm that you want nowhere near your home!
All in all, re-pointing is a small repair that can prevent money loss and headaches in the future. It’s much easier and more affordable to replace a few mortar joints than it is to completely rebuild your chimney. Let the certified professionals at Brickliners keep your masonry in good repair!
