What chimney cap installation actually involves

Without a cap, a flue is a pipe pointed straight up into roughly 7.5 inches of November rain, which is Seattle's average for that month. Anything falling in lands on the smoke shelf or the damper plate, rusting steel, soaking mortar and feeding musty smells. A cap solves that at the source. We measure the flue, or the full crown if several flues share it, choose a stainless cap whose mesh and dimensions suit the opening as well as the appliance below it, bolt it down and photograph the result.

Seward Park carries the heaviest tree cover in our area: of its 300-acre peninsula, about 120 acres are old-growth forest, with some trees older than 250 years. Houses shaded by that kind of canopy gather needles and twigs in every season, and the city's emergency managers point out that falling trees cause the most expensive windstorm damage to buildings. Under big trees, a cap keeps the flue clear between visits, and after any storm it is worth a look from the yard to make sure a branch has not knocked it askew.

What's included

  • Flue-by-flue measurements, or the whole crown for a multi-flue hood
  • Stainless cap with a spark screen matched to the opening
  • Firm fastening to the tile, the crown or the chase cover
  • A quick condition check of the crown or chase top while up there
  • Photos of the bare flue and the installed cap

Why it matters

An open flue lets in both weather and wildlife. Rainwater rusts the damper and soaks the liner, and a nest built across the top chokes the draft, which over a gas appliance can steer exhaust back into the house.

Spark arrestors have their own paragraph in Seattle's residential code, R1003.9.2, and its numbers trade ember control against draft. Measure the gaps in the screen, add them up, and the total must come to at least quadruple the flue opening. On durability, 19-gage galvanized and 24-gage stainless are the floor the code names for the wire. As for the holes, a ball half an inch across must not get through, while one three-eighths of an inch across must. Undersized caps and soot-clogged mesh fail that test, and the smoke ends up in the room. A prefabricated system takes only the termination its listing specifies.

How it works

What to expect with chimney cap installation

  1. 1

    Measure

    Tile dimensions, the number of flues and the crown's condition narrow down what will fit.

  2. 2

    Pick the hood

    One flue, several flues, or a prefabricated chimney with its own listed termination: each takes a different hood.

  3. 3

    Anchor

    Fixed so firmly that a winter windstorm leaves it exactly where it was installed.

Chimney Cap Installation — common questions

What does a new cap cost, fitted?

$235–$850, with installation included. The lower figure covers a standard single-flue cap; a multi-flue or custom-sized hood lands at the upper one.

Will a cap make my fireplace smoke?

Not if it is the right size. The code requires four times the flue outlet's area to stay open, and at that ratio the draft is not affected. Smoke after a new cap almost always means an undersized hood or mesh clogged with soot.

Is a cap mandatory under Seattle code?

Seattle's code wants each masonry chimney finished with a sloping concrete, metal or stone top, what the trade calls the crown, and it regulates spark arrestors when someone installs one. A separate metal hood over the flue opening is not listed as mandatory in the sections we reviewed; we recommend one anyway.

Could a cap end up blocking an appliance we never think about?

Yes, and the city chimney rule flags that very risk. A gas water heater, for example, may still share the flue, and the rule says to rule that out before any capping or removal. We trace every connection first.
