We never share your information
If your chimney is boxed and sided, a rusting metal lid is all that's protecting it.
Not every chimney is solid brick. Many homes have a factory-built chimney, a wood-framed "chase" wrapped in siding, and the flat metal cover on top is called the chase cover. It's the framed chimney's version of a crown, and it's the only thing keeping rain out of the wood structure underneath.
The problem is that most builders install cheap galvanized covers that rust, sag, and pool water within a few years. Standing water eats through the metal, then pours straight into the framing, and those orange streaks down your siding are the first warning.
Sloped to Shed, Not Pool
A proper cover is cross-broken so water runs off instead of collecting in the middle and rusting through.
Stainless or Copper, Not Rust-Prone Steel
We replace builder-grade galvanized with materials that don't corrode, so it never streaks your siding again.
Custom-Measured to Your Chase
Built to your exact dimensions and installed by certified & insured technicians, backed in writing.
Why the Original Cover Always Fails
Builders install the cheapest cover that passes inspection. Here is exactly how that decision comes back to leak into your framing, usually right on schedule.
It Pools Water
Flat, un-sloped covers sag in the middle and hold standing water instead of shedding it off the edges
It Rusts Through
Cheap galvanized steel corrodes from that standing water until pinholes, then open rust holes, form
It Streaks Your Siding
Rust runoff bleeds orange stains down the chase and siding, the eyesore neighbors notice first
It Leaks Into the Framing
Once it's rusted through, water pours into the wood chase, rotting framing and reaching your ceiling
It Never Fit Right
Generic covers with loose seams and wrong-size collars let water in around the edges from day one
Every one of these is designed out of a proper stainless or copper cover. Replace it once, and it's the last one you'll ever buy.

Signs Your Chase Cover Needs Replacing
A failing chase cover doesn't hide. It announces itself on your siding and, eventually, inside your home. Recognize any of these? The estimate is free.
Orange Rust Streaks on the Siding
The telltale sign. Rusty water runoff bleeding down from the top of the chimney means the metal cover is corroding and washing rust onto everything below it.
Standing Water or a Sagging Top
If you can see the cover dips in the middle or holds a puddle after rain, it's pooling water instead of shedding it and rusting from the inside out.
Visible Rust, Holes, or Pitting
Rust spots, flaking metal, or actual pinholes on the cover mean it's already failed. Every hole is a direct path for water into the framing.
Water or Stains Inside
Damp spots, stains, or a musty smell near the fireplace or on the ceiling below the chimney mean water has already made it through into the chase.
Loose, Lifting, or Rattling Metal
A cover that flexes, lifts at the edges, or rattles in the wind was never sealed right. Those gaps let water in around the seams, not just through rust.
It's the Original Galvanized One
If your framed chimney still wears its builder-installed cover, it's almost certainly thin galvanized steel on borrowed time. They aren't built to last, and they don't.
A new cover is a one-time fix. A rusted one keeps feeding water into wood framing, where the repair bill multiplies fast.

How We Replace a Chase Cover
A chase cover isn't a stock part you grab off a rack. It's measured and built for your exact chimney. Here's how it goes.
Measure the Chase Exactly
We take precise measurements of your chase top and every flue and collar that passes through it. A chase cover only seals if it's built to the right dimensions. Call (726) 259-1693 or send the form for a free estimate.
Fabricate It in Stainless or Copper
Your cover is custom-made from corrosion-proof stainless or copper, cross-broken so it slopes and sheds water, with collars sized to your flues. You choose the material, we build it to fit, no thin galvanized, no guesswork.
Remove the Old, Seal in the New
Out comes the rusted cover, and the new one is fitted, fastened, and sealed at the seams and collars so water can't sneak in around the edges. We check the cap and shroud on top while we're up there too.
Watertight & Warrantied
No more pooling, no more rust, no more streaks down your siding, for good. Installed by certified & insured technicians, documented for your records, and backed by our 3-year workmanship warranty in writing.
Buy the Last Cover Your Chimney Needs
The builder bought the cheapest one. We build the one you'll never have to think about again.
Stainless or Copper, Never Galvanized
We build in corrosion-proof materials that don't rust, sag, or streak, not the thin galvanized steel builders use to save a few dollars up front.
Custom-Measured to Fit
Every cover is fabricated to your exact chase and flue sizes, cross-broken to shed water. No generic cover forced to fit where it doesn't.
The Whole Top, One Job
Cover, collars, and cap sealed as a system. We handle the entire chimney top so there's no weak link left for water to find.
Certified, Insured & Warrantied
All work by certified & insured technicians, backed by a 3-year workmanship warranty in writing. If it ever fails us, we come back and make it right.
