Chimney Cap Installation in Green Lake, Seattle

A new chimney cap in Green Lake costs $265 to $850 installed. At $265 you get a stainless cap that clamps onto one flue tile. The top of the range is for a wide lid sheltering several flues at once, or for a cap made to measure where the crown fits no standard size. Roof pitch and stack height decide where a job sits between the two. When a cap is quoted during our $99 plus tax inspection, the inspection fee counts toward the cap if you approve it.

Why Green Lake homes need chimney cap installation

Material is the first choice. One Seattle chimney company publishes the service lives it expects: stainless steel, 15-20 years and beyond; copper, upward of 30; galvanized steel, a mere 5-10. That gap is the reason we install stainless as standard. The cap also has to stay put. WeatherSpark's windier season for Seattle lasts about 6.3 months, from October 15 to April 24, peaking in December, when the hourly mean reaches 5.1 mph, and for most of the year, September 20 to July 3 by that source, it blows chiefly from the south. A cap on a Green Lake roof is therefore fastened mechanically, never left to sit by its own weight.

Green Lake leaf fall and the mesh a cap is allowed to carry

The screen on a cap is a compromise between stopping things and letting smoke out. On a cap that includes a spark arrestor, R1003.9.2 of the residential code in force in Seattle governs the mesh. A ball of half an inch has to be held back and a ball of three-eighths let through, while the screen's open area has to total at least four times the flue outlet. Go finer and the screen clogs; go coarser and it no longer does its job.

That balance is tested around Green Lake every autumn. Seattle's emergency management office describes major windstorms with sustained winds of 60 to 70 mph and gusts up to 90, and names falling trees as a leading cause of the structural damage. Long before a limb comes down, the same wind strips leaves and small branches and drops them on roofs. We size the cap so its mesh area exceeds the code minimum and mount it high enough above the flue that litter slides off instead of matting across the opening.

Your chimney cap installation in Green Lake: what's included

Every chimney cap installation we do in Green Lake includes:

  • Flue tile and crown measured before a cap is ordered
  • Stainless steel cap with a lid sized to shed rain past the flue opening
  • Mesh sides to keep out birds, squirrels and leaves
  • Clamps or masonry anchors suited to the flue or crown
  • Old rusted cap removed and taken away
  • Photos of the crown and the fitted cap

Signs you need chimney cap installation in Green Lake

  • The flue is open to the sky when you look up past the damper
  • Rain is audible in the firebox during a downpour
  • Rust streaks run down the brick from the top
  • Twigs or nesting material have fallen onto the grate
  • The old cap rattles or has shifted off center after a storm

Why Green Lake homes need it

A cap adds height, and height is regulated. Section R1003.9 of the Seattle Residential Code wants the chimney top 3 feet clear of the roof where it emerges, and 2 feet clear of any roof or wall found inside a 10-foot radius. On older Green Lake houses with additions or dormers built after the chimney, the stack is sometimes shorter than that measure, which shows up as poor draft or smoke curling back toward an upstairs window. We measure the termination while we are up there and tell you what we find.

Your chimney cap installation in Green Lake, step by step

  1. 1

    Measure the top

    Each flue tile is measured on the outside, along with how far it projects from the crown; cracks in the crown are noted.

  2. 2

    Choose the cap

    Single-flue, multi-flue or custom, picked from the measurements and from what the flue serves.

  3. 3

    Fasten it down

    The cap is clamped to the tile or anchored into sound crown, with every fastener in stainless.

  4. 4

    Check and photograph

    We confirm the mesh is clear of the flue opening and send you pictures from the roof.

Chimney Cap Installation in Green Lake — common questions

Is a cap worth fitting on a flue that only serves a gas appliance?

If it vents through a masonry chimney, rain and animals get in the same way they would with a wood fire, so yes. A direct-vent unit is different: its termination comes from the factory and nothing is added to it.

Why not a cheaper galvanized cap?

Published local figures give galvanized steel 5 to 10 years against 15 to 20 or more for stainless. In a wet climate the cheaper cap is usually bought twice.

Can one cap cover two flues?

Yes. A multi-flue cap anchors to the crown and covers every opening under one lid, which also shelters the crown itself.
