Damage caused by a leaking chimney

Water poses a major hazard to your chimney, fireplace and your home. Water leaking into and around your chimney can cause rusted dampers, grates and doors in your fireplace. It can deteriorate your chimney or firebox masonry, cause staining on your chimney’s masonry or lead to a cracks, missing or deteriorated mortar joints between the clay flue tiles. If the water leaking from your chimney gains access to your home’s structure, it can discolor your walls or wall coverings, cause sagging ceiling or wallboard, or rot the wood supports of your home’s structure. Water in your chimney also can react with the creosote inside, filling your home with an unpleasant smell during the warm summer months.

Signs of water leaks

Because water can be so damaging to your chimney, it’s important to be on the lookout for signs that water is making its way into your chimney and fireplace system. Some signs are more obvious, while others are relatively subtle. Water pooling in the bottom of your fireplace is a clear indication that water is getting into your chimney. You also may notice rusting in your fireplace components. On the exterior of your home, cracked bricks or crumbling mortar can be a clear sign of water damage. Vegetation growth on the brick such as mold,mildew and algae can be observed. A less obvious sign is discoloration on your chimney’s bricks. Often, if water is penetrating chimney masonry, there will be whitish staining down the sides of the chimney bricks, this is called efflorescence.

Causes of water leaks

If water is leaking into your chimney, there are many possible culprits. A loose, displaced, damaged or missing chimney cap can allow water to pour down the insides of your chimney flue, causing a major problem. Cracked or deteriorated chimney crowns also can fail to direct water away from your flue and allow water to flow into your chimney. At the base of your chimney, where it meets the roof, there’s a protective flashing meant to seal the gap. That flashing can crack, corrode or develop holes, which means it will fail to prevent water from leaking in around the base of the chimney. Also if you have a large chimney the absence of a chimney cricket can allow water pool and not be properly diverted away from the base of the chimney.
