Chase Cover Replacement Brandywine, MD
A rusted or leaking chase cover in Brandywine can be replaced with a custom stainless steel or copper cover with a sloped top, drip edge and sealed collar around the flue. Call (240) 685-5322 to reach a local chimney sweep.
If your chimney is covered in siding instead of brick, it is probably a chase built around a metal flue. A chase cover is the metal lid on top of the chase, with a collar where the flue comes through. Everything inside the chase depends on that cover staying watertight.
The cover that comes with most homes is a thin galvanized pan, frequently with no slope at all. A flat galvanized pan collects water, rusts through and stains the siding below. By the time rust streaks show up, water may already be getting into the chase.
Once water gets in, it can travel down the chase and into the fireplace. Over time it leads to rot in the framing, rust on the fireplace and mold in damp areas. Catching a bad cover early keeps the repair simple.
Many chase cover replacement calls in Brandywine also turn up a need for chimney cap installation or chimney leak repair.

Call nowThe process
What happens during a chase cover replacement
Replacing a chase cover is mostly about getting the fit right.
Inspect the chase
The condition of the cover, collar and chase top is checked. Damage below the cover may need repair before the new cover goes on.
Take measurements
The outside dimensions of the chase, the flue location and the collar size are measured. Covers are usually custom fabricated to fit.
Pull the cap
The old chase top is removed, along with any rusted fasteners. Any damage underneath can then be seen.
Fit the new top
The new cover is set in place with its skirt over the siding and a hem that kicks water off the edge. Fasteners are placed so they do not create new leaks.
Seal the collar
The storm collar is sealed around the flue pipe and the chimney cap is reinstalled or replaced. The finished top is checked for gaps.
What is included
Chase cover work
Drip edges
A hemmed drip edge on the skirt kicks water away from the siding and reduce staining.
Cross break designs
A sloped or cross broken top keeps water from pooling and keep the cover drier.
Storm collars
The collar around the flue pipe is sealed, and the cap is replaced if it is worn so water cannot run down the flue pipe.
Stainless covers
A stainless cover holds up to weather for many years and can be powder coated to match the house.

Chimney Chase Repair Brandywine, MD
When a chase cover has leaked for a while, the chase itself often needs repair too. The work may include new framing, new sheathing, siding repairs and drying or replacing insulation. Flashing where the chase meets the roof is checked too.
If you are in Brandywine, tell the sweep about any water stains, soft siding or rust inside the fireplace when you call (240) 685-5322. Bigger framing repairs may involve a carpenter, while the cover and cap are handled by the sweep. Fixing the cover without fixing rot underneath only delays the problem.

What the local climate does to a chimney
Winters here are moderate, but cold nights still come regularly and fireplaces see real use from late fall into early spring. The ground and the masonry freeze and thaw many times each winter instead of staying frozen, and soaking rains in spring and fall test every crown and flashing joint. Warm, humid summers bring animals and damp odors to chimneys that sit unused. People in Brandywine, MD usually schedule their sweep in October or November.

Chase Cover Replacement FAQ
How long does a stainless steel chase cover last?
Quality covers in stainless or copper hold up for a long time. Good design keeps water off the cover and the siding. A yearly look at the chase top is a good habit.
Why is there water in my prefab fireplace?
A failed chase cover is one of the most common causes of water in a factory-built fireplace. That can rust the firebox, damage refractory panels and soak the area around the fireplace. A new cover and collar are often the fix.
What does a chase cover do?
A chase cover is the metal top on a framed chimney chase, the boxed enclosure around a factory-built chimney pipe. Its job is to keep water out of the framing, insulation and fireplace. The cap and cover work together to keep water out.
Should I patch or replace my chase cover?
A rusting cover tends to keep rusting around any patch. Most sweeps recommend replacement once rust has set in. Any rot underneath should be repaired at the same time.
Why is my chase cover rusting?
Many original chase covers are made of galvanized steel, which rusts once its protective coating wears away. Flat covers make it worse, since standing water sits on the metal. The rust then runs down the siding as brown streaks.
