Chimney Cap Installation in Hudson, Ohio

What does a chimney cap do?

• Keeps rain and snow out of the flue. Water inside a chimney damages the liner, the damper and the firebox, and in freeze-thaw it breaks masonry from the inside.
• Keeps animals out. Birds, squirrels and raccoons nest in open flues constantly, and a nest is both a blockage and a fire hazard.
• Stops embers leaving — the mesh acts as a spark arrestor.
• Reduces downdraft in wind, which is often the reason a room smells of smoke.

What kind of cap should go on?

Stainless steel, in nearly every case. Galvanised is cheaper and rusts out in a few winters, which stains the masonry on the way. Copper is excellent and costs more.

Sizing matters as much as material: the cap must clear the flue by enough to avoid restricting draft, and the mesh has to be fine enough to stop animals without blinding over with creosote. Multi-flue chimneys usually want a single full-coverage cap rather than separate ones.

Signs you need a cap or a new one

Water stains on the wall around the fireplace, a damp or musty smell in the firebox, rust on the damper, animal noise in the chimney, or a rusted-through cap visible from the ground. Hudson has a lot of steep, cut-up roofs on period homes, where step flashing at dormers and wall intersections is the usual leak point rather than the field.

We inspect it as part of any chimney flashing visit — see chimney flashing and repair in Hudson.
