Professional Chase Cover Replacement Services
If you have a prefabricated or factory-built fireplace encased in a wood, vinyl, or stucco chimney chase, the metal top shielding it from the elements is your chase cover. Original builders often install cheap, flimsy galvanized metal covers that rust out, sag, and leak after just a few years.
A rusted or failing chase cover allows water to pool on top and seep down inside your walls, rotting wooden chase framing, destroying fireboxes, and causing costly interior water damage. Our certified technicians replace deteriorating chase pans with custom-fitted, heavy-duty stainless steel or copper chase covers guaranteed to protect your home for a lifetime.
Why Original Builder-Grade Chase Covers Fail
Most factory-installed chase covers are made from thin galvanized sheet metal that is flat and unpitched. Over time, environmental exposure leads to rapid failure:
- Puddling & Water Pooling: Flat covers lack a sloping structure, allowing rainwater and melting snow to sit on top of the metal plate indefinitely.
- Rust & Corrosion: As protective zinc coatings wear off, galvanized steel reacts with air and water, rusting through completely and dripping rusty water down your siding.
- Oil-Canning & Sagging: Thermal expansion causes thin metal to warp and bow downward ("oil-canning"), forming a sink where water constantly accumulates.
- No Drip Edge Clearance: Builder-grade covers often sit flush against chase walls, allowing water runoff to stream directly down your siding or stucco, causing black streaks and rot.
Builder-Grade Galvanized vs. Custom Stainless Steel
Upgrading your chase cover is an investment in permanent protection. Here is how standard covers compare to our custom replacements:
| Feature | Builder-Grade Galvanized Steel | Custom Heavy-Gauge Stainless Steel |
| Lifespan | 5, 10 Years | Lifetime / Forever |
| Rust Resistance | Poor (rusts easily once zinc coating degrades) | 100% Rust-Proof & Corrosion-Resistant |
| Structural Design | Flat (pools water and sags over time) | Cross-Braked / Pitched (sheds water instantly) |
| Drip Edge | Flush or minimal overhang | 1.5″ to 2″ Drop Edge with Drip Diverter |
| Warranty | None or minimal builder warranty | Lifetime Material & Craftsmanship Guarantee |
Signs Your Chase Cover Needs Replacement
Don’t wait for a ceiling leak in your living room to inspect your chase cover. Watch for these clear warning signs:
- Rusty Stains on Siding or Brick: Red or orange rust streaks running down the exterior walls of your chimney chase.
- Pinging or Loud Metallic Pops: Loud "oil-canning" expansion noises coming from the top of the chimney on windy or hot days.
- Water Drops or Moisture in the Firebox: Finding water, damp ash, or rusted metal inside your prefabricated fireplace after a heavy storm.
- Water-Stained Drywall or Ceilings: Brown water rings or bubbling paint on ceilings or walls surrounding the chimney stack.
- Visual Sagging or Puddling: Visible dips or sitting water on top of the metal cover when viewed from the ground or roof.
