Northgate, King County
Our chimney repairs in Northgate begin at $425, which covers a contained fix such as a cracked crown sealed or a rusted damper replaced. Bigger jobs (a chase rebuilt, a firebox relaid, a stack taken down to the roof and put back) are priced from what the inspection finds. That visit costs $99 plus tax, and the amount leaves your repair bill once you accept the quote.

The south fork of Thornton Creek drains the Northgate area and Interstate 5 runs through it. Between creek and highway lies a district that barely existed before 1950. The mall's architect, John Graham Jr., planned room for 80 stores; by 1980 there were 123, and houses and apartment blocks had filled the old farm lots around them. The median year built in ZIP area 98125 is 1974.
FEMA's advisory on masonry chimneys was written after a California earthquake, and we use it for what it says about chimneys in general. Its point is that a damaged masonry chimney rebuilt as a copy of itself, in Northgate or anywhere, gains almost nothing against the next shock. It ranks the alternatives in three steps. If the fireplace is being given up, close the chimney off at roof level. If it is being kept, rebuild upward from the firebox as light framing boxed around a metal flue, with an insert or without. Best of all, in its rating, is a complete factory-built replacement. Each of those reconstructions, FEMA notes, needs a building permit.
This matters in Northgate because a factory-built system, where a house has one, is already the technology FEMA favors. Seattle's code requires such a chimney to be listed and labeled, holds its offsets to 30 degrees from vertical and allows no more than four elbows. Repairing one means using the parts its listing names, not generic sheet metal. For a brick chimney of the 1950s or 60s, we tell you when a repair is sound money and when the same sum would go further toward one of those three routes.
Every chimney repair we do in Northgate includes:

Book nowA chimney built in 1965 is not old by Seattle standards, but it has stood sixty winters. Sand Point, in northeast Seattle, logged an average of 24.0 days a year at 32°F or colder between 1986 and 2012, most of them from December through February, and roughly one day a year that never climbed above freezing. That is frost enough to widen a crack already holding water. On factory-built systems the weak points differ: the sheet-metal cover on top of the chase rusts through, and the framed chase beneath it rots out of sight.
Roof, attic and firebox are examined so the visible damage can be tied to its cause, which most often is water and the place it enters.
You get separate written figures for what is urgent and what is optional.
Roof anchors or scaffolding go up. For inside work, hearth and floor are covered.
Rusted metal is replaced in stainless, failed masonry is cut back to solid material and rebuilt, and refractory parts are swapped for ones that match the unit's listing.
Paired photos and the list of work done arrive with the invoice.

Northgate is a district that grew around the shopping mall opened in 1950 and joined Seattle in 1954, with postwar houses and apartments, in a ZIP area whose median build year is 1974. We work every part of it — Haller Lake, Pinehurst, Licton Springs included.

Four steps, each one on paper — so you always know what happens next.
Choose a genuine opening on the crew's calendar. Confirmation is immediate.
Liner, crown, cap, flashing and masonry examined in order — each finding photographed.
One document, plain numbers, covering only the work your chimney genuinely needs.
The repair is completed, then handed over with before-and-after photos of every item.
They start at $425. The written quote gives each repair its own price, so the total is never a surprise.
Not long. Once the cover leaks, water runs down inside the chase onto framing and onto the fireplace itself. A new cover is among the cheaper repairs; what it failed to protect is not.
A hairline crack is something to watch. A crack a coin slips into, or a panel that has crumbled, means the unit stays unlit until the panel is replaced with the manufacturer's part.
We repair when the structure is sound and the defect is local. When a masonry stack is loose from the roofline up, rebuilding or replacing it lasts longer, and we lay out both paths.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
