Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Black Diamond, WA
We’re Flint Chimney Sweep, a chimney company serving Black Diamond, WA with sweeping, inspection, and repair work. Black Diamond sits at the edge of the Cascades in east King County, and the homes here reflect it: older mining-era houses with original masonry, newer builds on hillside lots, and everything in between. The mix means a one-size-fits-all chimney approach doesn’t hold up. We put a written price in front of you before any tool comes off the truck, and every repair carries our 365-Day Done Right Promise in writing. Call (830) 251-4560 to set up a visit.
Why Black Diamond Homes Are Different
Black Diamond grew out of coal mining, and homes near the historic district often date to the early 1900s. Original brick chimneys from that era were built for coal burning, then asked to handle wood, then gas inserts. The liners in those older stacks are frequently undersized for modern appliances, and mortar joints have had a century of wet winters to erode. Newer construction around Ten Trails and Lawson Hills has its own profile: taller rooflines, steeper pitches, and chimneys framed through engineered trusses rather than masonry chases. That makes roof access on newer Black Diamond homes a more deliberate job, and it changes how we stage a sweep or inspection.
Wet weather is the constant. Black Diamond gets between 50 and 60 inches of rain a year, plus occasional snow that lingers on north-facing roofs in Morgan Creek and the neighborhoods off Roberts Drive. Moisture finds its way into hairline cracks, expands when it freezes, and accelerates spalling (brick face flaking off). We check for that on every visit because it’s the single most common repair issue we see out here. The terrain matters too: homes in the Lacamas area and along Tiger Mountain foothills often sit on slopes, which means ladder setup has to be level, and the chimney that looks easy from the street can require more care than it appears.
Our Main Black Diamond Services
The two jobs Black Diamond homeowners call us about most are chimney sweeping and chimney inspections, with repair work usually discovered in the course of one or the other. Each service has its own Black Diamond page with full detail and pricing.
Chimney Sweep in Black Diamond
A standard sweep in Black Diamond removes creosote and soot buildup from the flue and smoke chamber, clears any obstructions like bird nests or fallen leaves, and leaves the firebox cleaned out. Given the older housing stock near the historic center, we often find decades of accumulated creosote in chimneys that were cleaned rarely or not at all. Wet Black Diamond winters mean even a single burning season can produce enough creosote to make the next fire a risk. See rates and what’s included on the Chimney Sweep in Black Diamond page.

Chimney Inspection in Black Diamond
An inspection documents the condition of the flue liner, smoke chamber, crown, and exterior masonry, and it puts that in a written report with photos. For Black Diamond buyers and sellers, this is what catches deferred maintenance before closing. For current owners, it answers the question of whether last year’s sweep missed something structural. Older brick chimneys in the Lake Sawyer and Ten Trails areas show different wear patterns, so we don’t skip the exterior walk-around. Details and levels of inspection are on the Chimney Inspection in Black Diamond page.

Chimney Repair in Black Diamond
Repair work in Black Diamond divides roughly into two buckets: masonry (crown repair, brick repointing, flashing) and liners (stainless relining or HeatShield resurfacing on damaged flues). Homes in the older mining-era neighborhoods commonly need repointing; homes on exposed hillside lots frequently need crown work after freeze-thaw cycles. Every repair we quote is in writing with a one-year guarantee, and if a covered repair fails within that year, we return at no charge. Read specifics on the Chimney Repair in Black Diamond page.

The main driver of price in Black Diamond is flue condition. A chimney that hasn’t been swept in years, especially on an older home near the historic district, can show heavy glazed creosote that takes an extra pass and a second drop cloth. Roof pitch and ladder access on hillside lots in Ten Trails or near Lake Sawyer can also add setup time. What we don’t do is change the number at the door. The written price you approve is the price on the invoice, always.
