Chase Cover Replacement Sunbury, PA
The chase cover on a Sunbury 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. One call to (272) 238-4101 reaches a nearby sweep who handles chase covers.
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. It is what keeps rain and snow out of the chase.
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.
Water that gets past the cover can do real damage inside the chase. Over time it leads to rot in the framing, rust on the fireplace and mold in damp areas. The sooner the cover is replaced, the less damage there is to fix.
Depending on what the sweep finds, chase cover replacement in Sunbury, PA can go hand in hand with chimney cap installation and chimney leak repair.

Call nowThe process
What happens during a chase cover replacement
Replacing a chase cover is mostly about getting the fit right.
Look for damage
The chase is inspected from the roof for rust, holes and soft framing. Any rot in the framing is noted.
Take measurements
The outside dimensions of the chase, the flue location and the collar size are measured. Most replacement covers are made to order.
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.
Install the new 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. 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 finished top is checked for gaps.
What is included

Chimney Chase Repair Sunbury, 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 Sunbury, tell the sweep about any water stains, soft siding or rust inside the fireplace when you call (272) 238-4101. Some chase repairs need carpentry, so ask how that work is handled. Fixing the cover without fixing rot underneath only delays the problem.

Chase Cover Replacement Near Me
In Sunbury, many newer homes have prefab fireplaces with chimney chases and builder grade chase tops.

Chimneys in this climate
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 Sunbury is usually booked in the fall, before the first cold night.

Common questions about chase cover replacement
How long does a stainless steel chase cover last?
A stainless steel or copper chase cover can last for decades. Good design keeps water off the cover and the siding. Have it checked during chimney sweeping.
Should I patch or replace my chase cover?
Small holes can sometimes be patched, but patches on a rusting galvanized cover rarely last. A new stainless or copper cover with a slope usually solves the problem for good. The framing beneath should be checked while the cover is off.
What does a chase cover do?
The chase cover is the metal sheet that seals the top of a chimney chase, with an opening for the flue pipe. It keeps rain and snow out of the chase, which protects the framing and the fireplace below. The chimney cap is a separate part that sits on the flue above it.
Why is my chase cover rusting?
Builder grade chase tops are often galvanized steel, and they rust after years of weather. Water pooling on a flat cover speeds up corrosion. That rust washes down and stains the siding below.
Why is there water in my prefab 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.
