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.

We’ve been cleaning chimneys in Redmond long enough to know what the Cascade foothills do to a flue. Persistent moisture, short burn seasons, and a lot of converted gas inserts mean the average Redmond fireplace hides more than it shows. Our Chimney Sweep team sees it every week: a homeowner who burns a few fires each winter assumes the chimney is fine, and opens the damper to find a glazed creosote coating that a standard brush won’t remove.

Chimney Sweep Certified in Redmond
Chimney Sweep Certified work in Redmond means removing creosote, soot, and debris from the flue, smoke chamber, and firebox using professional rotary and hand-brush systems matched to the liner type. For most Redmond homeowners, this is an annual job triggered by fall, before the rainy season and the first freeze-thaw cycle hits the mortar. A standard Redmond sweep runs $189 to $329 for a single flue, with a second flue typically adding $79 to $119.
Creosote and Soot Removal
Creosote is the tar-like residue that condenses on flue walls when wood smoke cools too quickly. In Redmond’s damp air, short, infrequent burns produce dense, glazed Stage 3 creosote that no flat wire brush removes. We use rotary-chain systems and chemical treatments where needed, and we’ll tell you plainly if the flue needs more than a cleaning.
Annual Sweep and Fireplace Cleaning
An annual sweep in Redmond should happen before the first sustained freeze. Freeze-thaw spalling on already-weakened mortar gets worse every winter night, and you don’t want to discover a cracked flue liner the week you planned to light the first fire. We clean the firebox, damper, smoke shelf, and flue, then leave the hearth the way we found it.
Gas Fireplace Cleaning in Redmond
Gas Fireplace Cleaning in Redmond is for the many homes that converted from wood-burning masonry fireplaces to sealed gas inserts during the 2000s and 2010s. The gas appliance itself needs regular service, but the real issue is what’s left behind: an abandoned clay liner that may be unsized, deteriorated, or coated in old creosote. Cleaning runs $149 to $249 for a standard gas insert service in Redmond.
Insert and Liner Assessment
When a gas insert is installed into an original masonry chimney, the old clay liner often stays in place. That liner needs to be assessed for clearance, deterioration, and blockage before anyone assumes the setup is safe. We inspect the connection, check the existing flue, and flag any condition that would prevent returning the fireplace to wood-burning use.
Firebox and Glass Service
We clean the glass, logs, burner, and pilot assembly, then check for proper venting and carbon monoxide risk. Many Redmond homeowners have never had the firebox behind a gas insert cleaned, and it’s often coated in years of dust and fine soot. You get a written report of what we found and what we did.
Trusted Brands We Service in Redmond
We work with the brands chimney professionals actually specify, not whatever the box store had on sale. Our Redmond trucks carry parts and components from DuraFlex liner systems, HeatShield resurfacing material, and Olympia Chimney caps and dampers. When a Redmond chimney needs more than a sweep, we typically have the right component on the truck rather than ordering it and making you wait. Gas insert service calls often involve Famco and Copperfield components, which we source directly from professional supply lines. No improvised substitutes. No generic hardware. You get a written price before any of those parts go in.
Common Chimney Sweep Problems We See in Redmond Homes
- Glazed third-degree creosote in seldom-used fireplaces. Short, infrequent burns in Redmond’s damp air don’t get hot enough to burn off creosote as it forms, so it condenses into a dense, shiny coating on flue walls. This is the single most common finding on Bear Creek and Education Hill chimneys.
- Abandoned clay liners after gas conversions. Overlake and Education Hill homes often have a gas insert boxed into an original masonry chimney, with the old clay flue left behind unlined and uninspected. That liner needs sizing and condition checks before the fireplace is ever returned to wood use.
- Moss on chimney crowns and eroded mortar joints. Redmond’s wetter, cooler microclimate keeps chimney crowns damp for months each year, and moss roots widen hairline cracks. Combined with freeze-thaw nights, this produces spalling brick and leaking smoke chambers.
- Deteriorating prefab metal fireplace flues at Redmond Ridge. The 2000s-era homes at Redmond Ridge have prefabricated metal fireplaces with manufacturer-mandated inspection intervals. Skipping those inspections means small rust spots become unsafe venting failures.

FAQs About Chimney Sweep in Redmond
A rarely-used fireplace is often the dirtiest one we open. Short, occasional burns in Redmond’s persistently damp air produce dense, glazed creosote that would burn off in a hot, frequent fire but instead sticks to flue walls and hardens. Meanwhile, moisture from the wetter western Cascade climate is working on the mortar joints even when no fire is lit. Annual sweeping catches both problems. Call (336) 863-3889 to schedule yours before the rainy season.
Yes, it’s a different protocol. Prefabricated metal fireplaces at Redmond Ridge have manufacturer-specified cleaning and inspection requirements, and we follow the OEM guidelines for your specific unit. Metal flues corrode differently than clay tile, and we check for rust, warping, and joint separation rather than creosote glazing alone. If your unit hasn’t been serviced in several years, the inspection matters as much as the cleaning. Call (336) 863-3889 and we’ll check the manufacturer’s requirements for your model.
Third-degree glazed creosote won’t come off with a standard hand brush. It requires rotary chain systems, chemical treatments, or both, and sometimes a HeatShield resurfacing if the underlying flue is also compromised. This is common in Redmond homes where short, infrequent burns left a shiny tar-like coating. We’ll show you photos from the camera inspection so you see exactly what we’re describing before agreeing to any work. Call (336) 863-3889 for a sweeps assessment.
Redmond sits just west of the Cascades and receives slightly heavier rainfall than Seattle, with persistent low-level moisture that keeps chimney crowns damp and encourages moss growth. Moss roots widen micro-cracks in the crown, and repeated freeze-thaw cycles through mild but genuinely freezing winter nights spall the mortar. Annual inspection before the rainy season catches this early, when a crown repair is a few hundred dollars instead of a full rebuild. Call (336) 863-3889 to get yours scheduled.
The original clay liner is still in that chimney, and it was likely never resized or inspected after the conversion. We’ll assess the abandoned liner, check clearances, and clean the firebox and insert so the entire system is safe, whether you keep burning gas or return to wood. This is a conversation Redmond chimney sweeps have constantly because so many Overlake and Education Hill homes converted in the 2000s. Call (336) 863-3889 and we’ll send a technician with a camera to look inside yours.
