What chimney cap installation actually involves

An open flue on the Northshore takes in rain for most of the year. WeatherSpark gives Kirkland a wetter season of about 6.8 months, and water falling straight down the chimney rusts dampers and soaks the smoke chamber. Birds and squirrels use the same opening in spring. A cap closes it. A cap is also on the State Fire Marshal's short list of heating safety habits. We measure the flue and crown, fit a stainless cap that suits the chimney, and secure it so it stays through the windy months.

WeatherSpark records Kirkland's windier months as roughly mid-October to late April, with December the windiest. On a lakefront roof with a clear view of the water, a cap has to be fastened well enough to stay put through that season.

What's included

  • Measurement of each flue and of the crown before fitting
  • Stainless single-flue or multi-flue cap
  • Spark arrestor mesh built into the cap
  • Removal of any debris or nest found in the top of the flue
  • Photos of the finished installation from the roof

Why it matters

Keeping water and animals out of the flue is cheaper than repairing what they do inside it, which is why fire-safety advice puts the cap next to the yearly inspection and cleaning.

A capless flue lets rain run straight onto the damper and smoke shelf, and it gives nesting animals an entrance. A nest or a pile of leaves is also a blockage, and a blocked flue can send smoke and carbon monoxide back into the house. The cap's mesh doubles as a spark arrestor. Where one is installed, Washington's residential code sets how it must be built: an open area no smaller than four times that of the flue outlet, a screen that resists heat and corrosion, openings that stop spheres larger than half an inch, and a cap or screen that can be taken off for cleaning.

Chimney Cap Installation — common questions

Do I really need a chimney cap?

In a climate this wet, yes. It keeps rain off the damper and smoke shelf, keeps animals out, and its mesh stops sparks from landing on the roof.

What does a new cap cost, installed?

Our range is $235–$850. A single standard flue sits at the lower end; wide multi-flue chimneys and custom sizes cost more.

What is the difference between a cap and a spark arrestor?

A spark arrestor is the mesh screen; the cap is the cover above it. Most of the caps we fit combine the two, and the screen comes off for cleaning.

Can a cap fix a leaking chimney?

Only if water is coming straight down the flue. If it enters at the crown, soaks through the brick or slips past the flashing, the cap alone will not stop it, and the inspection tells you which it is.

An animal is already in my chimney. What should I do?

Do not light a fire. Call us: we clear the flue, check for damage, and fit a cap so it does not happen again.
