For homeowners in Central Florida, a chimney is often more than just a functional vent for a fireplace; it is a structural component that must withstand intense tropical weather. While traditional masonry chimneys are common, many modern Orlando homes utilize prefabricated chimney systems. These systems rely on a “chase”, the wooden or metal structure surrounding the flue, and a “chase cover” to stay watertight. At Ducts All Done, we specialize in professional chimney chase and chase cover replacements, ensuring your home remains protected from the torrential rains and high humidity characteristic of the Sunshine State.
What is a Chimney Chase and Why Does it Fail?
A chimney chase is the framed box that houses the silver double-walled chimney pipe. To the outside world, it looks like a standard chimney finished with siding, stucco, or brick. However, the most critical part of this assembly is the chase cover (also known as a chase pan). This is the large metal “lid” that sits on top of the chase to shed water away from the structure.
In the Orlando area, many builders originally installed “builder-grade” galvanized steel chase covers. Over time, Florida’s salty air and high moisture levels cause this galvanized coating to fail, leading to significant rust and corrosion. Once a chase cover rusts through, water enters the wooden framing of the chase, leading to wood rot, mold growth, and eventually, structural failure that requires a full chimney chase replacement.
Signs You Need a Chimney Chase Cover Replacement
Recognizing the early warning signs of a failing chase cover can save you thousands of dollars in structural repairs. Because the top of your chimney is rarely visible from the ground, it is important to look for these “red flags” around your property:
-
Rust Stains: Reddish-brown streaks running down the sides of your chimney siding or stucco are a primary indicator that the metal pan on top is oxidizing.
-
Water in the Firebox: If you see moisture or hear dripping inside your fireplace after a typical Orlando thunderstorm, your chase cover likely has holes or failed seals.
-
Musty Odors: A damp, earthy smell coming from the fireplace often indicates that water has infiltrated the wooden chase and started a mold cycle.
-
Siding Damage: Bubbling paint or rotting wood near the top of the chimney structure suggests the “drip edge” of the chase cover is no longer effectively diverting water.
Our Premium Solution: Stainless Steel Chase Covers
When Ducts All Done performs a chimney chase cover replacement in Orlando, we don’t just swap one problem for another. We replace failing galvanized steel with high-grade 304 Stainless Steel. Unlike standard steel, stainless steel is inherently rust-resistant and designed to last a lifetime in the Florida climate.
Our custom-fabricated covers feature cross-breaks, diagonal creases in the metal that create a slight peak. This ensures that water does not “pool” in the center of the pan, which is the leading cause of premature failure in flat builder-grade covers. We also ensure a proper drip edge and a secure storm collar fit, providing a comprehensive seal that meets the rigorous standards of the Chimney Safety Institute of America (CSIA).
The Full Chimney Chase Replacement Process
If the water damage has already progressed past the metal cover and into the framing, a simple cover replacement may not be enough. In these cases, our team handles the full structural restoration. This process involves removing the damaged exterior siding, replacing any rotted 2×4 framing or OSB sheathing, and ensuring the internal flue pipe is still properly supported and aligned.
We adhere to the Florida Building Code for all structural repairs, ensuring your chimney is not only beautiful but also safe and compliant. Proper ventilation is essential for fire safety, and our technicians are trained to maintain the necessary clearances between the hot flue pipe and the combustible wooden materials of the chase during the rebuilding process.
Protecting Your Orlando Home from Water and Pests
A damaged chimney chase is an open invitation for more than just water. In Central Florida, open gaps in a rusted chase cover are prime real estate for birds, squirrels, and raccoons. These animals can bring in nesting materials that create fire hazards or blockages. By installing a precision-fitted, custom-made stainless steel chase cover, you are creating a permanent barrier against both the elements and local wildlife.
Furthermore, a well-maintained chimney system contributes to your home’s overall energy efficiency. If your chase is leaking air, your HVAC system has to work harder to combat the hot, humid air being pulled into your attic and living spaces. Sealing the “envelope” of your home starts at the roofline, and the chimney is one of the most vulnerable points in that envelope.

Frequently Asked Questions
How long does a stainless steel chase cover last? Unlike galvanized steel, which may only last 7 to 10 years in Florida, a high-quality stainless steel chase cover is often a “lifetime” repair, resistant to rust even in coastal environments.
Can I just paint over the rust on my current cover? Painting is a temporary cosmetic fix. Rust is like a cancer for metal; it continues to eat through the material from underneath the paint. If you see rust streaks, the structural integrity of the metal is already compromised.
Does a chase cover replacement require a permit? In many cases, minor repairs do not, but a full structural chimney chase replacement may require a permit from the City of Orlando or Orange County to ensure it meets fire safety codes.
