The Importance of Waterproofing Your Chimney
Anyone who resides in Western New York knows that in the Greater Buffalo and Rochester regions, we experience extreme weather conditions that can wreak havoc on even the most well-built chimneys. The constant freeze-thaw cycles and heavy precipitation can lead to various problems, including spalling bricks, deteriorating mortar, and water infiltration. These issues can compromise your chimney’s structural integrity, create safety hazards, and increase energy costs.
Why Waterproof Your Chimney
Waterproofing is a crucial investment to safeguard your chimney and prevent costly repairs in the long run. It involves applying a protective coating to the chimney’s exterior, creating a moisture-resistant barrier that prevents water, snow, and ice from penetrating the masonry. However, before proceeding with waterproofing, it is essential to have a thorough chimney inspection conducted by a certified chimney professional.
The Importance of Chimney Inspections Before Waterproofing
At Felgemacher, we strongly recommend homeowners schedule a chimney inspection before waterproofing. This inspection will help determine the extent of any existing damage, such as spalling bricks or missing mortar. If masonry deterioration is present, tuckpointing may be necessary to replace the decaying mortar and restore the chimney’s structural integrity. Once these repairs are complete, a waterproofing coating can be applied to provide long-lasting protection.
Common Signs of Chimney Water Damage
Here are some common signs that your chimney may have existing water damage:
- Efflorescence: This is a white, chalky residue that forms on the bricks of your chimney. It’s a sign that water is penetrating the masonry.
- Damaged chimney crown or cap: A cracked or broken chimney crown or missing or damaged chimney cap can allow water to enter the chimney.
- Damaged bricks or mortar: Look for cracks, spalling, crumbling mortar, and loose or missing bricks.
- Water stains: Look for water spots around the chimney and dampness or staining on interior walls and ceilings near the chimney. These are clear indicators of a potential chimney leak.
- Wet firebox: Water or bits of clay in the firebox are signs that your chimney may have water damage.
- Rust-covered bricks: Rust stains dripping down the brickwork from the chimney cap or chase cover often indicate water damage.
- Moldy odors: A musty or moldy odor from the chimney or surrounding area is a strong indicator of water damage.
If you notice any of these signs, it is vital to have your chimney inspected by a professional as soon as possible before it causes more extensive damage.
Water-based Sealant
It’s important to note that Felgemacher Masonry & Chimney uses a professional-grade water-based sealant formulated to waterproof masonry chimneys. Masonry professionals use this type of sealant because of its vapor-permeable membrane. The “breathable” membrane allows moisture to escape from the brickwork, preventing it from becoming trapped and causing further damage. This is crucial because trapped moisture within the masonry can lead to further damage, including efflorescence (white, powdery deposits) and spalling.
