Chase Cover Replacement Natrona Heights, PA
A rusted or leaking chase cover in Natrona Heights can be replaced with a custom stainless steel or copper cover with a sloped top, drip edge and sealed collar around the flue. Call (724) 604-6450 to reach a local chimney sweep.
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.
Many chase covers installed by builders are made of galvanized steel, and they are often flat. Water pools on a flat galvanized top until rust sets in, and then it leaks. Rust stains on the siding are often the first visible sign of a failing cover.
A leaking chase cover lets water soak the framing, insulation and fireplace below. 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.
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
Replacing a chase cover is mostly about getting the fit right.
Check the top
The condition of the cover, collar and chase top is checked. 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. Most replacement covers are made to order.
Remove the old cover
The cap comes off first, then the old cover is unscrewed and lifted away. 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. 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 sweep makes sure water has nowhere to get in.
What is included
Chase cover options
Stainless covers
A stainless cover holds up to weather for many years and do not leave rust streaks.
Copper tops
Copper is a long lasting option for homes where looks matter.
Skirt hems
The edge of the cover is bent so water drips clear of the chase instead of soaking into it.
Cross break designs
A sloped or cross broken top keeps water from pooling which is the main fix for flat pans.

How the weather here affects chimneys around Natrona Heights
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. Most homeowners in Natrona Heights, PA schedule a sweep in early fall, and a repair check after a hard winter.

Common questions about chase cover replacement
Why is there water in my prefab 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.
How long does a stainless steel chase cover last?
Quality covers in stainless or copper hold up for a long time. 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. 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 is a chase cover?
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.
Why are there rust streaks on my chimney siding?
Builder grade chase tops are often galvanized steel, and they rust after years of weather. Water pooling on a flat cover speeds up corrosion. The rust then runs down the siding as brown streaks.
