Chimney Repair Cost in Seattle (2026): Crown, Repointing & Rebuild Prices

What Does Chimney Repair Cost in Seattle in 2026?

Chimney repair in Seattle costs $332 – $5,528, tax included, for the four masonry repairs on the local price grid: crown repair, mortar repointing, brick replacement and structural repair. A rebuild is a different job with a different price: $4,422 – $11,608 to rebuild the part above the roofline, and $17,688 – $30,954 for a full rebuild from the ground up.

Smaller jobs sit on their own lines: chimney caps at $221 – $497 for a single flue, flashing repair and reseal at $332 – $774, waterproofing at $387 – $884. Every price starts with a professional chimney inspection at $99 plus tax — deducted from the quote you approve, so you know which line you are on before you pay for any work.

Based on over 850 chimney repair jobs our crew completed across the Seattle metro area last year, the most common repair is tuckpointing deteriorated mortar joints.

Seattle Chimney Repair Price Table (2026)

Every amount below comes from the same price grid as our pricing page and the chimney repair page. Repairs and rebuilds are listed apart because they are two different jobs.

Where a job lands inside its range depends on what the inspection finds: how far the damage goes, the chimney's height, and how hard the roof is to reach.

Repair or Rebuild: How Do You Tell Which One You Need?

The price grid splits three jobs into a repair line and a bigger line. Here is what usually puts a chimney on one side or the other.

• Structural repair ($1,658 – $5,528) or rebuild above the roofline ($4,422 – $11,608): a repair keeps the existing masonry. Loose or cracked sections are reset and the joints are rebuilt. A rebuild above the roofline is quoted when the top of the stack has moved, leans, or has so many spalled bricks that resetting them would not hold. A chimney that leans visibly from the street is rarely a repair.
• Rebuild above the roofline ($4,422 – $11,608) or full rebuild ($17,688 – $30,954): the full rebuild, from the ground up, is for damage that goes below the roof: a shifted foundation, a cracked base, or a stack that has pulled away from the house. If the problem stops at the roofline, the smaller rebuild is the one on the table.
• Flashing repair & reseal ($332 – $774) or full replacement ($663 – $1,548): a reseal works when the metal is sound and only the seal has let go. Full replacement is for flashing that is rusted through, bent, or was never set into the mortar joints.

Crown repair has a single line on the grid ($332 – $995). A crown too far gone to patch is priced from what the inspection finds, not from a published line. Only an inspection on the roof settles which line you are on. That is why it comes first: $99 plus tax — deducted from the quote you approve.

Chimney Crown Repair: Signs, Sealing or Replacement

The crown is the concrete or mortar slab that seals the top of the masonry around the flue. It is not the same part as the chimney cap: the cap is the metal cover over the flue opening, the crown covers the whole top of the stack. The two can fail separately. A well-built crown slopes outward, overhangs the brick by about 2 inches so water drips clear of the face, and is poured in air-entrained concrete that stands up to freezing. Many crowns on older Seattle homes were poured too thin, in plain mortar mix, with no overhang at all.

Why crowns crack. Water that gets into a crack freezes on cold nights and widens it. The flue heats up during a fire while the outer crown stays cool, and that difference opens cracks over time. Moss holds water against the surface and speeds both up.

Signs of a damaged crown:

• Water in the firebox after rain
• White staining (efflorescence) or spalling brick on the top courses, just below the crown
• Moss or plants growing on top of the chimney
• Broken edges or dark crack lines, often visible from the yard with binoculars

Sealing or replacement. Hairline cracks, up to about 1/8 inch, on a crown that is still in one piece can be sealed with a flexible elastomeric crown sealant. Cracks wider than 1/4 inch, missing sections, or a crown with no drip edge call for a new crown. Crown repair is on the price grid at $332 – $995; a crown too far gone to patch is priced from what the inspection finds. One thing to avoid: roofing tar spread over a crown traps moisture and makes the brick spall faster.

Where Do These Prices Come From?

What Pushes a Chimney Repair Price Up or Down in Seattle?

The range on each line is wide on purpose. Here is what moves a job toward the low or the high end:

• How far the damage goes: repointing a few joints near the crown sits at the bottom of the $442 – $1,658 range; repointing all four faces of a two-story chimney sits at the top.
• Height and roof access: tall chimneys and steep roofs on hillside streets in Queen Anne, Capitol Hill or Magnolia take more setup, sometimes scaffolding.
• Historic materials: many pre-1940 homes, common in Ballard and Ravenna, were built with soft brick and lime mortar. Matching them takes a softer mortar mix; hard Portland cement against soft brick causes the brick to spall.
• Water already inside: a leak caught early is a crown or flashing line. Water that has soaked the masonry for several winters can move the job to repointing, brick replacement, or a rebuild.
• Salt air: homes near Puget Sound, in West Seattle and Magnolia, see faster corrosion on metal caps, flashing and dampers.

What Are the Most Common Chimney Repairs in Seattle?

Based on our service records from 2025, here are the five most frequently needed chimney repairs across the Seattle metro, ranked by job volume:

1. Mortar repointing ($442 – $1,658): The single most common repair we perform — about 38% of all repair calls. Rain drives moisture into mortar joints, which crack and crumble over the decades. Failing mortar lets water into the brick itself, which is how a repointing job turns into brick replacement or a rebuild.
2. Crown repair ($332 – $995): the concrete or mortar slab on top of the chimney takes the full weight of the rain. Hairline cracks let water in, and the crown breaks down from the inside.
3. Flashing repair ($332 – $774): the metal seal where the chimney meets the roof. When it separates, water tracks down inside the wall, often showing up as a stain beside the fireplace.
4. Chimney cap ($221 – $497 for a single flue): caps get dented, rusted or blown off. Beyond keeping rain out, a cap keeps birds and raccoons out of the flue. Stainless steel outlasts galvanized in this climate.
5. Liner repair or replacement ($1,658 – $4,422 for stainless steel): clay tile liners crack from heat cycles and chimney fires, and some older homes have no liner at all. NFPA 211 is the reference standard for liners.

How Can You Tell If Your Chimney Needs Repair?

Watch for these signs year-round, and especially after a wet winter or a big storm:

• White chalky stains (efflorescence) on exterior brick — salt left behind by water moving through the masonry
• Rust streaks on brick or inside the firebox
• Crumbling or missing mortar between brick courses, especially near the crown
• Water stains on the ceiling or wall next to the chimney
• Flaking or spalling brick faces
• Visible cracks in the chimney crown (often visible from the yard with binoculars)
• A musty or smoky odor in the room even when the fireplace isn't in use
• Smoke backing into the room when the damper is open — sometimes a sign of a damaged liner

If you see any of these, the right next step is a Level 1 or Level 2 chimney inspection before the next fire. It is $99 plus tax — deducted from the quote you approve, and you get a written quote for the work.

How to Keep Chimney Repair Costs Down in Seattle

1. Book an inspection every fall: at $99 + tax, a September or October inspection catches loose mortar, crown cracks and flashing gaps while they are still on the repair lines, not the rebuild lines.
2. Schedule masonry work in spring or summer: mortar and crown compounds cure best in dry, mild weather. May through August is the best window in Seattle.
3. Waterproof every few years: a chimney waterproofing treatment ($387 – $884) keeps water out of the masonry while letting it breathe. Water inside the brick is what turns a repair into a rebuild.
4. Don't sit on small repairs: in a wet climate, each crack lets in more water, which widens the next one. In 14 years serving Seattle, we've seen small repairs turn into rebuilds because a homeowner waited two extra seasons. The gap between the top of the repointing line ($1,658) and the bottom of a rebuild above the roofline ($4,422) is the cost of waiting.
5. Keep photos for insurance: if the damage follows a storm, a fallen tree or another sudden event, take photos before any repair begins and ask our technician for written notes you can send your insurer.
