The island's housing is largely mid-century and later, with a strong belt of 1950s–70s homes through the centre and larger waterfront properties around the perimeter, many of them remodelled more than once. Masonry chimneys serving open wood-burning fireplaces are still the norm away from the newer builds.

What's included

Your chimney sweep in Mercer Island

Every chimney sweep we do in Mercer Island includes:

  • Full flue brushed top to bottom, smoke chamber and firebox
  • Level 1 visual inspection included
  • Debris and nesting material cleared from the flue and cap
  • Crown checked for moss and cracking
  • Before-and-after photos of the flue interior

Why Mercer Island homes need it

Tree cover is the recurring factor. Overhanging firs and maples drop needles and debris straight into uncapped flues, and they shade the stack so it never fully dries between rains — which is why we see more moss on Mercer Island crowns than almost anywhere else on the Eastside. Damp masonry plus a cool flue also means slower draw and more condensation, and condensation is what turns ordinary soot into the sticky, glazed creosote that needs a proper mechanical sweep rather than a quick brush.

See the difference

Chimney Sweep in Mercer Island — common questions

How much does a chimney sweep cost on Mercer Island?
$189–$449, Level 1 inspection included. Multi-flue homes are quoted per flue before we begin.
There is moss growing on our chimney — is that a problem?
It is a symptom worth acting on. Moss holds water against the crown and the top courses of masonry, and on a shaded island stack it rarely dries out. Left alone it accelerates cracking. Removal is usually bundled with the sweep.
Why does our fireplace draw poorly?
On the island the usual causes are a damp, cool flue that never establishes draft, a partially blocked cap, or debris from overhanging trees. The Level 1 that comes with the sweep tells you which one it is.
