Chimney Chase Cover Replacement in Stuart, FL

What a Chase Cover Does

A factory-built fireplace usually has a metal flue pipe that runs up through a wooden chase on the outside wall or roof. The chimney chase cover is the sheet of metal across the top of that chase. The flue pipe passes through a hole in it, a storm collar seals that joint, and a cap sits on the pipe above.

When the cover is flat, rain pools on it. Galvanized steel then rusts through, water runs into the chase, and the framing, insulation and the fireplace itself start to suffer.

Custom Stainless Steel Chase Covers

A good custom chase cover is made to the exact size of your chase, with a raised center or cross-break so water runs to the edges, a skirt that laps over the siding and a drip edge that throws water clear of it. We recommend a stainless steel chase cover because it holds up to rain and humidity far longer than galvanized steel or aluminum.

Chimney chase cover replacement also means a new storm collar and, usually, a new chimney chase cap on the flue pipe, matched to the fireplace maker's listed parts.

Repair or Replace

Chase cover repair is possible when the metal is sound and only the sealant or fasteners have failed. Once rust has pitted the top or it sags enough to hold water, replacement is the lasting fix. Chase cap replacement on its own makes sense when the cover is fine but the cap on the pipe has rusted or blown loose.

Checking the Chase Itself

When the old cover comes off we look down into the chase. Wet insulation, rotted plywood or rusted framing tell us how long water has been getting in. If the chase framing or siding needs repair, we explain it separately so you can decide what to do first.
