Chase Cover Replacement Jarrettsville, MD
The chase cover on a Jarrettsville home with a factory-built fireplace can be swapped for one that sheds water before rust and standing water cause leaks into the chase and fireplace. Dial (443) 899-3079 to talk with a local chimney pro about your chase.
Homes with prefab fireplaces often have a chimney chase, which is a framed box around the metal flue pipe. A chase cover is the metal lid on top of the chase, with a collar where the flue comes through. Its job is to keep water out of the framing and away from the fireplace below.
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. Over time it leads to rot in the framing, rust on the fireplace and mold in damp areas. Replacing the cover early is far easier than repairing a rotted chase.
If the problem goes deeper than it first looked, a Jarrettsville chimney sweep may also recommend chimney cap installation or chimney leak repair.

How chase cover replacement works
A chase cover has to be sized to the chase and the flue, so measuring comes first.
Inspect the chase
The chase is inspected from the roof for rust, holes and soft framing. Soft wood under the cover is a sign of a longer leak.
Take measurements
The outside dimensions of the chase, the flue location and the collar size are measured. Covers are usually custom fabricated to fit.
Take off the old top
The cap and old cover are removed carefully so the flue pipe is not disturbed. This is the best time to look for rot.
Set the cover
A sloped stainless or copper cover is fitted and fastened through the side skirt. Fasteners are placed so they do not create new leaks.
Reinstall the cap
The storm collar is sealed around the flue pipe and the chimney cap is reinstalled or replaced. The sweep makes sure water has nowhere to get in.
What is included
Chase cover work
Stainless covers
A stainless cover holds up to weather for many years without needing paint.
Copper tops
A copper chase top adds a finished look and resists corrosion that weathers to a natural color.
Chimney caps
A new storm collar and cap finish the top to keep out animals and rain.
Sloped tops
Shaped tops shed water instead of holding it so rust has less chance to start.

Chimney Chase Repair Jarrettsville, MD
When a chase cover has leaked for a while, the chase itself often needs repair too. Rotted studs, soft plywood, damaged siding and soaked insulation are the usual problems. Flashing where the chase meets the roof is checked too.
Calling (443) 899-3079 from Jarrettsville with details about stains or leaks helps the sweep plan the visit. Chase repairs may involve a carpenter or siding contractor for larger framing work. Fixing the cover without fixing rot underneath only delays the problem.

How the weather here affects chimneys around Jarrettsville
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. Masonry takes the worst of it from the freeze and thaw cycle: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, which is how cracks, loose bricks and leaks start. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. That is why chimney cleaning in Jarrettsville is usually booked in the fall, before the first cold night.

Chase Cover Replacement FAQ
How long does a stainless steel chase cover last?
A stainless steel or copper chase cover can last for decades. Shape matters as much as material, since a sloped top sheds water. Inspections every year catch problems early.
Should I patch or replace my chase cover?
A rusting cover tends to keep rusting around any patch. Replacing it with a sloped stainless or copper cover is the more lasting fix. The framing beneath should be checked while the cover is off.
What is a chase cover?
A chase cover is the metal top on a framed chimney chase, the boxed enclosure around a factory-built chimney pipe. Without it, water would run straight into the chase. A cap sits on top of the flue pipe that comes through the cover.
Can water from a chase cover damage my fireplace?
Water from a leaking chase cover often runs down the flue pipe or framing and into the fireplace. It can lead to rust, damaged panels and stains around the fireplace. The sweep will check the cover, collar and cap to find the source.
Why is my chase cover rusting?
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.
