Chimney Caps and Animal Protection

A good cap keeps rain, leaves, and animals out of the flue. If something has already moved in, we get it out and close the opening for good.

Signs you need this

  • Scratching, chirping, or rustling sounds from the chimney
  • Sticks, leaves, or nesting material in the firebox
  • No cap, or a rusted, bent, or loose cap
  • Rain dripping into the fireplace

What’s included

  • Removal of nests and debris from the flue
  • Stainless steel or copper caps sized to your flue or crown
  • Mesh screening that stops animals and sparks
  • Check of the flue for damage after animal removal

Why a cap matters

An open flue is an easy way in for rain, leaves, and animals. Water rusts dampers and breaks down the masonry from the inside. Nests block exhaust, which can push smoke and carbon monoxide back into the house. A mesh cap solves all three problems and also stops sparks from landing on the roof.

When animals are already inside

We check what’s there, remove the nest and debris, and inspect the flue for damage. Then we cap the chimney so it doesn’t happen again.

Common questions

Are there animals you can't remove right away?

Some birds, such as chimney swifts, are federally protected while nesting. In that case, we'll explain the timing and cap the chimney once the nest is empty.

What kind of cap should I get?

A single-flue cap covers one flue. A multi-flue or full-crown cap covers the whole top, which also protects the crown. We recommend based on your chimney's layout.
