Chase Cover Replacement Long Valley, NJ
The chase cover on a Long Valley home with a factory-built fireplace can be swapped for one that sheds water sized to the chase and shaped to shed water off the edges. Call (908) 867-1003 to reach a local chimney sweep.
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.
Builder grade chase covers are usually galvanized steel cut flat across the top. 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 Long Valley 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.
Check the top
The sweep checks the old cover, the storm collar, the cap and the siding near the top. 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 cap and old cover are removed carefully so the flue pipe is not disturbed. This is the best time to look for rot.
Fit the new top
The new cover goes on with a slope or cross break so water runs off, and a drip edge that sheds water away from the siding. 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. The finished top is checked for gaps.
What is included
Chase cover work
Storm collars
A new storm collar and cap finish the top to keep out animals and rain.
Stainless covers
Stainless steel covers resist rust far better than galvanized steel and do not leave rust streaks.
Copper chase covers
Copper covers last a long time and develop a patina over time that pairs well with copper flashing.
Skirt hems
A hemmed drip edge on the skirt kicks water away from the siding instead of soaking into it.

Chimney Chase Repair Long Valley, NJ
A failed chase cover can lead to damage inside the chase, from the framing to the fireplace.

Leaks can come from the roof line as well, so the flashing gets a look.

How the weather here affects chimneys around Long Valley
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. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Long Valley is usually booked in the fall, before the first cold night.

Chase Cover Replacement FAQ
Can a leaking chase cover be repaired?
Patching a rusted chase cover is usually a short term fix. Most sweeps recommend replacement once rust has set in. Any rot underneath should be repaired at the same time.
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. A yearly look at the chase top is a good habit.
Why is my chase cover rusting?
Builder grade chase tops are often galvanized steel, and they rust after years of weather. Flat covers make it worse, since standing water sits on the metal. The rust then runs down the siding as brown streaks.
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 chimney cap is a separate part that sits on the flue above it.
Why is there water in my prefab fireplace?
Water from a leaking chase cover often runs down the flue pipe or framing and into the fireplace. Over time, it can rust the metal firebox and flue and damage panels. Replacing the cover and storm collar usually stops it.
