Maple Valley, King County
Masonry repair on a Maple Valley chimney starts at $425. This page is about two jobs: fixing or recasting the crown, the concrete lid poured across the top of a brick chimney, and repointing, which means cutting out worn mortar joints and refilling them. Both are priced by how much surface is involved, and both are quoted in writing after a roof-level look.

A crown has one task, which is to send water off the top of the chimney instead of into it. Washington's residential code describes what that takes: the top must be capped in concrete, metal or stone and sloped to drain, it needs a drip edge, and a caulked break has to separate cap from flue liner so the two can move separately. Many crowns were simply troweled flat in mortar, and flat mortar cracks. In Maple Valley those cracks then spend a wet season that WeatherSpark measures at about 7.3 months taking in rain.
Every masonry repair (crown / repointing) we do in Maple Valley includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowCold finishes what rain starts. WeatherSpark gives Maple Valley an average December low of 36°F, and the station records for this part of the county show more freezing nights toward the foothills than on the valley floor: about 60 a year at Kent against about 80 at Landsburg, farther up the Cedar River. Water held in a crack or a soft joint expands when it freezes. Shade makes it worse. Moss, Oregon State University Extension explains, does not attack a surface directly but traps debris and holds moisture against it, and a chimney under firs stays damp long after the rain stops.
From the roof we photograph the crown and each side of the chimney and probe the joints to find where sound mortar begins.
The quote separates crown work from repointing and gives a price for each, which lets you tell the urgent item from the one that could wait a season.
Failed mortar is removed with a grinder and hand tools, moss is brushed off and dust is cleared so new material bonds.
New mortar is pressed in and tooled to the profile the old joints had. The crown gets a pitched top and an overhanging edge, and a flexible joint isolates it from the flue liner.
Until it has set, new work stays under cover from rain. We come back to the photos to confirm every marked defect was addressed.

From $425. A few cracks sealed in a sound crown sit near that figure. A full new crown, or repointing a tall stack on all four sides, is a bigger bill; the quote gives the measured area the price is based on.
Book the $99 plus tax visit. We photograph the masonry from the roof and write the quote from what we see, and the $99 is credited to the job if you approve it.
Yes, before any mortar work, and gently. Oregon State University Extension warns that careless pressure washing can damage roofing, so around a chimney we brush and scrape by hand.
The clearer months. In Maple Valley, WeatherSpark's clearer season opens around June 18 and closes around October 6, which gives mortar and concrete the dry days they need to cure.
