Chase Cover Replacement Avonmore, PA
A rusted or leaking chase cover in Avonmore can be replaced with a custom stainless steel or copper cover before rust and standing water cause leaks into the chase and fireplace. Dial (724) 817-2006 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. It is what keeps rain and snow out of the chase.
Many chase covers installed by builders are made of galvanized steel, and they are often flat. 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 running down the chase is usually the first clue.
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.
If the problem goes deeper than it first looked, an Avonmore chimney sweep may also recommend chimney cap installation or chimney leak repair.

Call nowThe process
The chase cover replacement process
A chase cover has to be sized to the chase and the flue, so measuring comes first.
Inspect the chase
The sweep checks the old cover, the storm collar, the cap and the siding near the top. Any rot in the framing is noted.
Measure the chase
The outside dimensions of the chase, the flue location and the collar size are measured. A good fit matters more than anything else.
Take off the old top
The old chase top is removed, along with any rusted fasteners. The framing below is checked once it is exposed.
Set the cover
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. It is fastened through the skirt, not through the top.
Reinstall the cap
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.

Chimney Chase Repair Avonmore, PA
Chase repair goes hand in hand with replacing a cover that has been leaking. Common repairs include replacing rotted framing and sheathing, fixing or replacing siding, resealing trim and replacing wet insulation. Leaks can come from the roof line as well, so the flashing gets a look.
If you are in Avonmore, tell the sweep about any water stains, soft siding or rust inside the fireplace when you call (724) 817-2006. Bigger framing repairs may involve a carpenter, while the cover and cap are handled by the sweep. Rot under the cover needs attention before the new cover goes on.

What the local climate does to a chimney
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. The hardest thing on brick here is not the cold itself but the constant swing above and below freezing: 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 Avonmore is usually booked in the fall, before the first cold night.

Chase Cover Replacement questions
What does a chase cover do?
It is the metal lid on top of a chimney chase, which is the framed box around a prefab chimney. 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.
How long does a stainless steel chase cover last?
Quality covers in stainless or copper hold up for a long time. A sloped design and drip edge help it last by keeping water moving. Have it checked during chimney sweeping.
Why is my chase cover rusting?
Builder grade chase tops are often galvanized steel, and they rust after years of weather. Flat tops that hold water rust faster. Those streaks are a sign the cover needs replacing.
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. Replacing the cover and storm collar usually stops it.
Can a leaking chase cover be repaired?
Patching a rusted chase cover is usually a short term fix. 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.
