Chimney Cap Installation in Portland, OR

A chimney cap is small and inexpensive, but it does big work — keeping rain, animals, and debris out of your flue while blocking sparks and downdrafts. We install and replace stainless steel and copper caps throughout the Portland metro.

What Does a Chimney Cap Do?

The cap is the metal cover with a mesh screen that sits on top of your chimney's flue. It's one of the cheapest parts of a chimney, but skipping it is one of the most expensive mistakes a homeowner can make. A good cap protects your chimney in four ways at once:

  • Keeps rain out — water in the flue rusts dampers, damages liners, and causes leaks
  • Blocks animals — birds, squirrels, and raccoons love to nest in open flues
  • Stops debris — leaves and twigs can clog the flue and become a fire hazard
  • Catches sparks — the mesh screen helps prevent embers from landing on your roof

Signs You Need a New Cap

  • No cap at all on one or more flues
  • A rusted, dented, or blown-off cap
  • Animals or birds getting into the chimney
  • Water dripping or rain noise inside the firebox
  • A missing or damaged spark screen

How Much Does a Chimney Cap Cost?

In the Portland area, a single-flue stainless steel cap typically runs $150 to $600 installed. Multi-flue caps that cover the entire chimney top, and custom copper caps, cost more. We measure your flue precisely so the cap fits and seals correctly.

Our Installation Process

  • Measure the flue (or chimney top for multi-flue caps) for an exact fit
  • Recommend the right cap style and material for your chimney
  • Securely fasten the cap and seal as needed for a weather-tight fit
  • Confirm the spark screen is intact and the cap is solidly anchored

A new cap works hand in hand with a solid crown and waterproofing to seal your chimney against Portland weather.
