Chase Cover Replacement DuBois, PA
A chimney sweep in DuBois can replace the metal cover on top of a framed chimney chase before rust and standing water cause leaks into the chase and fireplace. One call to (814) 913-0171 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. The top of the chase is sealed with a metal chase cover that has an opening for the flue pipe. It is what keeps rain and snow out of the chase.
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 running down the chase is usually the first clue.
A leaking chase cover lets water soak the framing, insulation and fireplace below. Over time it leads to rot in the framing, rust on the fireplace and mold in damp areas. Catching a bad cover early keeps the repair simple.
Chase Cover Replacement is often paired with chimney cap installation and chimney leak repair, depending on the cause.

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.
Look for damage
The sweep checks the old cover, the storm collar, the cap and the siding near the top. Any rot in the framing is noted.
Size the cover
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 old chase top is removed, along with any rusted fasteners. The framing below is checked once it is exposed.
Install the new cover
The new cover is set in place with its skirt over the siding and a hem that kicks water off the edge. It is fastened through the skirt, not through the top.
Seal the collar
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
Chimney caps
The collar around the flue pipe is sealed, and the cap is replaced if it is worn so water cannot run down the flue pipe.
Stainless steel chase covers
Stainless steel covers resist rust far better than galvanized steel without needing paint.
Copper tops
A copper chase top adds a finished look and resists corrosion for homes where looks matter.
Drip edges
The edge of the cover is bent so water drips clear of the chase which protects trim and siding.

Chimney Chase Repair DuBois, PA
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. Leaks can come from the roof line as well, so the flashing gets a look.
If you are in DuBois, tell the sweep about any water stains, soft siding or rust inside the fireplace when you call (814) 913-0171. Chase repairs may involve a carpenter or siding contractor for larger framing work. The new cover should go on a sound chase.

What the local climate does to a chimney
Winters here are long and cold, and the heating season usually runs from October well into April. Masonry takes the worst of it from the freeze and thaw cycle: 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. Most homeowners in DuBois, PA schedule a sweep in early fall, and a repair check after a hard winter.

Common questions about chase cover replacement
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. 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?
A well made stainless or copper cover often outlasts the galvanized original by many years. Shape matters as much as material, since a sloped top sheds water. 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. Most sweeps recommend replacement once rust has set in. Any rot underneath should be repaired at the same time.
Why are there rust streaks on my chimney siding?
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. 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. That can rust the firebox, damage refractory panels and soak the area around the fireplace. The sweep will check the cover, collar and cap to find the source.
