Chimney chase cover replacement in Callahan

Gaps that let animals into the chase

A cover that no longer fits tightly, a skirt pulled away from the siding or a missing storm collar can leave openings at the top of the chase. Birds, squirrels and other animals use such gaps to reach the enclosure. If you have heard activity, tell us before any work, because an occupied space has to be handled before it is closed. Once the chase is clear, the new cover and a sound cap close the entry points.

Covers on chases with vinyl siding

Vinyl siding expands and contracts with temperature more than wood, stucco or fiber cement, and it is installed to move. A skirt pinned tight against vinyl can restrict that movement and distort the panels. We fasten through the skirt into solid framing at the corners and sides and leave the siding free to move. If the top course of siding is damaged, we note it for separate repair. On a chase that was re-sided in vinyl over older siding, the added thickness also changes the skirt size we order.

Tall chases on two-story homes

A chase that runs up a two-story wall puts the cover high above the ground, where it catches stronger wind than a short chase on a one-story roof. Access takes more setup, and the cover needs firm fastening on all sides. We plan the equipment for the height, and we discuss sheet thickness and fastener spacing with that exposure in mind before you approve the work on your Callahan home. On a very tall chase, a thicker sheet or a stiffer shape keeps the cover from drumming in wind.

What to tell us when you call

A few details help us plan the inspection of your Callahan chase, and none of them requires a ladder. You do not need to know the metal or the fireplace model. If you still have closing papers or the fireplace manual, those help too. If the fireplace is on a second floor or behind furniture, mention it so we plan the inside look as well.

• When you first noticed rust, stains or noise
• Whether the fireplace burns wood and is still in use
• Whether the roof or siding was replaced recently
• How many stories the chase rises
