However, sometimes you may notice water and rust around your fireplace, which can be a cause for concern. In this blog post, we will explore the possible reasons behind this issue and discuss potential solutions.

1. Problematic Rainwater Drainage:

One common reason for water and rust around the fireplace is inadequate rainwater drainage. If the rainwater is not properly directed away from your fireplace, it can seep into the brickwork or masonry, leading to water stains, dampness, and eventually rusting of any metal components. Poorly functioning gutters or downspouts can contribute to this problem, as heavy rainfall can overload the system and result in water overflowing near the fireplace.

To address this issue, it is crucial to ensure that your rainwater drainage system is working properly. Regularly inspect the gutters and downspouts, clean them from debris, and make sure they are securely attached to your home’s exterior. If necessary, consider adding extensions or diverters to direct the water away from your fireplace.

2. Leaking Chimney Cap:

Another potential source of water and rust around your fireplace is a leaking chimney cap. The chimney cap serves as a protective barrier against water, animals, and debris, but it can deteriorate over time due to weather exposure or insufficient maintenance. When the chimney cap becomes damaged or develops cracks, rainwater can easily enter the chimney, causing water stains and rusting of any metal components within.

To resolve this issue, have a professional chimney sweep inspect and replace the damaged chimney cap. They will ensure that the new cap is properly fitted and sealed to prevent any future leaks.

3. Damaged Flashing:

Flashing is a vital component that prevents water from entering the gap between the chimney and the roofline. If the flashing becomes damaged or improperly installed, water can find its way into your fireplace, causing water stains and rust in the process. Common causes of flashing damage include harsh weather conditions, improper installation techniques, or simply aging and deterioration over time.

If you suspect that damaged flashing is the cause of your water and rust problem, it is best to hire a professional chimney contractor to assess the situation and make the necessary repairs. They will ensure that the flashing is correctly installed, providing a strong barrier against water infiltration.

4. Moisture in the Masonry:

Water and rust around the fireplace can also be caused by moisture trapped within the masonry itself. Masonry materials, such as bricks, mortar, and concrete, are porous, meaning they easily absorb moisture. Factors like heavy rain, condensation, or a leaky chimney can contribute to excess moisture, leading to water stains and rusting of any metal components.

To address this issue, consider applying a waterproofing sealant to the external masonry surfaces of your fireplace. This sealant will create a barrier against water penetration, protecting the masonry and preventing the onset of rust. It is essential to choose a high-quality sealant product and follow the manufacturer’s instructions for proper application.


Water and rust around your fireplace can indicate various underlying issues that require attention. Whether it’s problematic rainwater drainage, a leaking chimney cap, damaged flashing, or excessive moisture in the masonry, it is crucial to identify and address the root cause to prevent further damage. Consult with a professional if you are unsure or unable to resolve the issue yourself, as they have the expertise and knowledge to provide the most effective solutions for your specific situation.
