Those rust streaks running down your chimney siding are the builder-grade cover announcing its retirement. We measure on-site, fabricate in stainless steel, and install in one visit — the last chase cover your home should ever need.
If your home was built in DFW anytime since the 1980s, there's a strong chance your "chimney" is actually a chase — a framed, siding-clad structure housing a metal flue — with a flat galvanized steel lid on top. That lid, the chase cover, was almost certainly the cheapest component on the entire roofline. Galvanized covers rust through in 10 to 15 North Texas years, and when they do, every rain drains into the chase: onto the flue pipe, the framing, and eventually your ceiling.
Lowes Chimney Sweep replaces failed covers with custom-fabricated stainless steel — measured to your exact chase dimensions, cross-broken so water sheds instead of pools, and installed with a properly sealed storm collar. It's a one-visit permanent fix for chase cover replacement across Dallas Fort Worth, and one of the most satisfying before-and-afters we do: rust streaks gone, leak gone, problem gone. Homeowners in 98 DFW cities have made it one of our most-requested services.
Spotted the streaks or the drips? Call (214) 225-8874 — measurement visits are quick, and quotes are written before anything is fabricated.
Galvanizing is a thin zinc coating over ordinary steel. Sun, rain, and pooling water wear the zinc away, and the steel beneath begins rusting the day that happens. The rust streaks on your siding are dissolved cover metal, washing downhill.
Many original covers were fabricated dead flat, so water sits on them after every rain — and standing water probes every seam, fastener hole, and collar joint until it wins. That's why our replacements are cross-broken: bent to peak slightly at the center so water runs off in all four directions.
Stainless doesn't depend on a coating — the metal itself resists corrosion. Fabricated to fit with a proper drip edge, skirt, and cross-break, a stainless cover outlasts the siding around it. Copper is available for homeowners who want the look; galvanized is available nowhere on our truck.
Water inside a wood-framed chase rots what holds your flue up. Call (214) 225-8874 before the repair grows.
Custom metal fits or it fails, so the process is built around precision:
Exact chase dimensions, flue positions, and pitch — no universal-fit guesswork
Stainless standard, copper optional — priced before fabrication begins
Cross-break, drip edge, and collar opening formed to your measurements
Rusted cover off, chase top cleared of debris and standing water
Framing and flue checked for water damage while everything's exposed
New cover fastened, storm collar set and sealed around the flue
Before-and-after documentation — satisfying every single time
A rusted-through cover leaks with every rain. One measurement visit starts the permanent fix.
(214) 225-8874Because your chase wasn't built to a catalog size. Off-the-shelf covers rely on being "close enough," and close enough is exactly how water gets in at the skirt and collar. Fabricating to your measurements costs a bit more once — and ends the replacement cycle.
Barely. The work happens entirely at the chase top — typically one to two hours, no interior access needed, nothing staged through your living room. Most homeowners just hear a little rooftop activity and then get shown the photos.
Then you'll see it in photos before we close it up — and you'll be glad we looked. Water-softened framing or a corroded flue section is far cheaper to address while the chase top is open. If everything's sound, we tell you that too, and the new cover goes on over a clean bill of health.
Yes — the cover protects the structure, not the fire. An unused fireplace under a leaking cover still means rotting framing, rusted flue pipe, and eventually interior water damage. The chase needs a working lid whether you burn or not.
Every cover starts with a tape measure on your actual chase — dimensions, flue positions, overhang. The result fits like it was born there, because dimensionally, it was.
The fabrication detail that separates a 50-year cover from a 5-year one. Water hits our covers and leaves; it never sits, so it never wins.
We install the material we'd put on our own homes. No galvanized "value option" that restarts the rust clock — stainless standard, copper by request.
While the cover is off, the framing, flue, and cap get inspected — and if the roofline flashing shows storm damage from the same hail that killed your cover, you'll know before we leave.
Rust-streaked, sagging, pooling covers replaced with gleaming stainless — chase cover projects from Frisco, Grapevine, and Prosper are waiting in the gallery.

Masonry chimney instead of a chase? Your equivalent protection is the concrete crown — that's covered on our chimney crown repair page.

Most custom stainless steel chase cover replacements in Dallas Fort Worth run $600 to $1,400 installed, depending on chase size, flue configuration, and material. Copper and oversized covers run higher. Your written Free Online Quote covers measurement, fabrication, and installation — one number, no surprises.
If your chimney is a framed structure covered in siding, stucco, or brick veneer rather than solid masonry, that structure is a chase, and it houses a metal flue pipe from a prefab fireplace. Most DFW homes built since the 1980s have chases. The flat metal lid on top is the chase cover.
The classic tell is rust streaks running down the chase siding below the cover. Other signs: water dripping into the fireplace, standing water visible on a flat cover, popped or missing fasteners, and rust flakes around the storm collar. Any of these means water is already getting past the cover.
Paint hides rust; it doesn't stop it. Once galvanized steel's zinc coating fails, corrosion continues under any coating, and the pinholes that leak are already forming. Painting buys months and complicates the eventual replacement. A stainless replacement ends the cycle permanently.
Stainless steel is the DFW workhorse — it doesn't rust, handles hail, and typically carries a lifetime expectation. Copper is beautiful and equally durable at a premium price. Galvanized steel is what builders installed originally, and its 10-to-15-year rust-through is why you're reading this page. We fabricate in stainless as standard.
A cross-break is a slight X-shaped bend fabricated into the cover's surface so it peaks at the center and sheds water toward the edges. Flat covers pool water, and pooled water finds every seam and fastener. It's a small fabrication detail that decides whether a cover lasts 5 years or 50.
The site visit for measurement takes about 30 minutes; fabrication of your custom cover follows; and installation is typically completed in one visit of one to two hours, including removal of the old cover, a chase-top check, and sealing of the new storm collar.
Brushed stainless reads as clean neutral metal on virtually every siding and trim color, and copper develops a patina many homeowners choose specifically for its look. Since each cover is fabricated to your exact chase dimensions, the fit looks intentional — because it is.
Frequently, yes — hail-dented and punctured covers are commonly covered storm damage, while ordinary rust-through from age usually isn't. We document the damage and the completed replacement with dated photos your adjuster can use. Confirm specifics with your policy.
Often it's smart. The cap mounts on or through the chase cover, so if the cover rusted out, the cap has weathered the same years — and replacing both in one visit avoids disturbing a new cover later. We'll assess the cap during measurement and quote it separately so the choice stays yours.
The chase top is a small neighborhood where everything ages together. These are the services most often bundled with a cover replacement — or discovered necessary once the old lid comes off:
