Chase Cover Replacement Robbinsville, NJ
The chase cover on a Robbinsville home with a factory-built fireplace can be swapped for one that sheds water before rust and standing water cause leaks into the chase and fireplace. One call to (609) 765-0143 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.
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. Rust running down the chase is usually the first clue.
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. Replacing the cover early is far easier than repairing a rotted chase.
If the problem goes deeper than it first looked, a Robbinsville chimney sweep may also recommend chimney cap installation or chimney leak repair.

Call nowThe process
What happens during a chase cover replacement
Replacing a chase cover is mostly about getting the fit right.
Check the top
The sweep checks the old cover, the storm collar, the cap and the siding near the top. Soft wood under the cover is a sign of a longer leak.
Size the cover
The chase top is measured, along with the flue opening and its position. Most replacement covers are made to order.
Take off the old top
The old chase top is removed, along with any rusted fasteners. This is the best time to look for rot.
Fit the new top
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
A sealed storm collar and cap close up the opening at the flue. The finished top is checked for gaps.
What is included
What chase cover replacement covers
Copper tops
Copper is a long lasting option that pairs well with copper flashing.
Cross break designs
A sloped or cross broken top keeps water from pooling and keep the cover drier.
Skirt hems
Drip edges stop water from running down the siding instead of soaking into it.
Chimney caps
The collar around the flue pipe is sealed, and the cap is replaced if it is worn for a complete watertight top.

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, and each winter widens the cracks a little more. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. That is why chimney cleaning in Robbinsville is usually booked in the fall, before the first cold night.

Chase Cover Replacement FAQ
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. Without it, water would run straight into the chase. 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. Flat covers make it worse, since standing water sits on the metal. Those streaks are a sign the cover needs replacing.
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. It can lead to rust, damaged panels and stains around the fireplace. The sweep will check the cover, collar and cap to find the source.
Should I patch or replace my chase cover?
Patching a rusted chase cover is usually a short term fix. Most sweeps recommend replacement once rust has set in. Ask the sweep to check the framing under the cover too.
How long does a stainless steel chase cover last?
A stainless steel or copper chase cover can last for decades. A sloped design and drip edge help it last by keeping water moving. Have it checked during chimney sweeping.
