Chase Cover Replacement Severn, MD
A rusted or leaking chase cover in Severn can be replaced with a custom stainless steel or copper cover sized to the chase and shaped to shed water off the edges. Dial (443) 899-3081 to talk with a local chimney pro about your chase.
If your chimney is covered in siding instead of brick, it is probably a chase built around a metal flue. The chase cover, sometimes called a chase top or chase pan, is the metal sheet that caps the top of that enclosure. 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. Flat covers hold standing water, and galvanized steel rusts once the coating wears, which leaves brown streaks down the siding and eventually holes in the pan. Rust stains on the siding are often the first visible sign of a failing cover.
Once water gets in, it can travel down the chase and into the fireplace. It can rot the wood framing and sheathing, soak insulation, rust the metal fireplace and flue pipe and leave stains on ceilings or walls near the fireplace. Replacing the cover early is far easier than repairing a rotted chase.
Chase Cover Replacement is often paired with chimney cap installation and chimney leak repair, depending on the cause.

The chase cover replacement process
Here is how a sweep usually handles a chase cover replacement.
Check the top
The condition of the cover, collar and chase top is checked. Any rot in the framing is noted.
Take measurements
Exact measurements are taken so the new cover fits snugly. Covers are usually custom fabricated to fit.
Take off the old top
The cap comes off first, then the old cover is unscrewed and lifted away. The framing below is checked once it is exposed.
Set the cover
A sloped stainless or copper cover is fitted and fastened through the side skirt. Screws go through the sides so the top stays watertight.
Finish the top
The storm collar is sealed around the flue pipe and the chimney cap is reinstalled or replaced. A final look confirms the cover is secure.
What is included
Chase cover work
Storm collars
A new storm collar and cap finish the top so water cannot run down the flue pipe.
Copper chase covers
Copper covers last a long time and develop a patina over time that pairs well with copper flashing.
Drip edges
A hemmed drip edge on the skirt kicks water away from the siding and reduce staining.
Sloped tops
A sloped or cross broken top keeps water from pooling and keep the cover drier.

Chase Cover Replacement Near Me
In Severn, many newer homes have prefab fireplaces with chimney chases and builder grade chase tops. From Severn out to neighboring towns like Gambrills, Jessup, Odenton and Elkridge, sweeps regularly find rusted chase tops on homes that are only a decade or two old, which is why a chase cover is worth checking when the chimney is swept.

How the weather here affects chimneys around Severn
Winters here are long and cold, and the heating season usually runs from October well into April. The hardest thing on brick here is not the cold itself but the constant swing above and below freezing: rain and melting snow soak into the crown and joints, then freeze and push them apart, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Severn is usually booked in the fall, before the first cold night.

Common questions about chase cover replacement
What is a chase cover?
The chase cover is the metal sheet that seals the top of a chimney chase, with an opening for the flue pipe. Without it, water would run straight into the chase. The cap and cover work together to keep water out.
Should I patch or replace my chase cover?
Patching a rusted chase cover is usually a short term fix. A new stainless or copper cover with a slope usually solves the problem for good. Ask the sweep to check the framing under the cover too.
Why are there rust streaks on my chimney siding?
Many original chase covers are made of galvanized steel, which rusts once its protective coating wears away. Water pooling on a flat cover speeds up corrosion. That rust washes down and stains the siding below.
Can water from a chase cover damage my fireplace?
When a chase top leaks, the water usually ends up in the fireplace below. It can lead to rust, damaged panels and stains around the fireplace. A new cover and collar are often the fix.
How long does a stainless steel chase cover last?
Quality covers in stainless or copper hold up for a long time. Shape matters as much as material, since a sloped top sheds water. Inspections every year catch problems early.
