Chimney sweep and repair across King County
One crew, twenty miles from central Seattle, covering all ten cities below.
No obligation. Someone answers every day, 7 a.m. to 9 p.m.
The short answer
Nation Wide Chimney Sweep&Repair works a twenty-mile radius centered on Seattle, which covers the bulk of King County’s chimney stock: the brick Craftsman cores of Seattle itself, the postwar eastside suburbs around Bellevue and Kirkland, the newer tract neighborhoods of Redmond, and the valley floor south through Renton and Kent. One crew, one set of tools, and the same sweep, inspection, repair and cap work wherever the address falls inside that circle. The county’s chimneys split roughly by decade and by drainage: pre-1950 brick stacks in the older cores carry mortar and crown problems the newer neighborhoods rarely see, while the postwar and modern subdivisions lean on factory-built, metal-chase systems that fail at the cap and the flashing instead. Both kinds of work run through the same crew and the same truck.
Local specifics
What is true about King County
- 01
King County’s building stock spans more than a century, from pre-1900 Seattle brick cores to 1980s tract subdivisions in Redmond and Kent, so a single truck routinely sees both a hand-set lime mortar joint and a factory-built metal chase.
- 02
The county sits inside the Puget Sound Clean Air Agency’s jurisdiction, which can call a Stage 1 or Stage 2 burn ban on any wood-burning fireplace or stove during stagnant winter air, regardless of which King County city the address is in.
- 03
Seattle averages roughly 150 days a year with measurable rainfall, and that wet load does not stop at the city line — it drives the same crown cracking, moss growth and flashing failures across every King County suburb this business reaches.
- 04
The Seattle Fault runs east-west through the county, from Bremerton through West Seattle and south Seattle, and it is the same fault the U.S. Geological Survey documented breaking more than 1,500 chimneys in the 2001 Nisqually earthquake.
Housing stock
What the housing stock means for the chimney work
County-wide, chimney work splits along one line: pre-1960 masonry versus factory-built metal. The older brick stacks in Seattle, Burien and pockets of Renton need mortar, crown and flue-liner attention as the joints wash out under King County’s rain. The newer factory-built systems common from the 1970s onward in Redmond, parts of Bellevue and the Kent Valley fail at the cap, the storm collar and the chase flashing instead, and any replacement part on those has to match the original manufacturer’s listing rather than a generic masonry cap.

Anthony Gill
Water started dripping into our attic during heavy rain so we knew the chimney needed attention fast. Team showed up prepared and diagnosed a completely eroded concrete crown and pulled-away flashing. …
Gregory Phillips
Moved into a new-to-us house in Ballard with a gorgeous brick fireplace but no service history. Scheduled an inspection to be safe. …
Loretta Green
It was important to us to feel safe about our tall chimney after the recent earthquake. The crew carefully checked it out from the inside and the roof. They found some loose cement joints and a crown that was slightly off-center. …
Leona Green
The tech was sweeping the roof from the top down and took images revealing a damaged chimney crown and weak mortar joints on the chase. Clear visual proof, no hard sell!

Questions
What people ask about King County
Does Nation Wide Chimney Sweep&Repair cover all of King County?
Coverage runs a twenty-mile radius from central Seattle, which reaches Seattle, Bellevue, Kirkland, Redmond, Renton, Shoreline, Burien, Mercer Island and Kent. Call with your address and we will confirm whether it is covered.
Do burn bans in King County affect chimney inspections or repairs?
No — a Puget Sound Clean Air Agency burn ban restricts using a wood-burning fireplace or stove, not having it serviced. Sweeps, inspections, repairs and cap work go ahead on any day, banned or not.
Is one company really enough for a county this size?
One crew working a defined twenty-mile radius means the same technician who repoints a 1920s Wallingford stack fits factory-built caps in a 1990s Redmond subdivision the same month — the tools and the appointment book cover both.
How do I know which King County city page applies to my address?
Use whichever city your property sits in — Seattle, Bellevue, Kirkland, Redmond, Renton, Shoreline, Burien, Mercer Island or Kent. If the address falls just outside a listed city, call and we will confirm whether it is inside the twenty-mile radius.
Does older King County housing need different chimney work than newer housing?
Generally, yes. Pre-1950 brick stacks need mortar, crown and liner attention as the joints age; homes built from the 1970s on typically carry factory-built metal chimneys that fail at the cap and flashing instead of the masonry.
