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.

AfterFast, Reliable Fireplace Services Across Mercer Island
Fireplace services on Mercer Island typically run $185-$390 for gas or wood-burning units, and most repair work we quote in writing before anything starts. The island’s older masonry chimneys, many original to homes built in the 1950s through 1970s, fail in predictable ways we see almost weekly: spalling fireboxes, missing clay-tile flue sections, and chimney caps matted with Douglas fir needles. If your fireplace smokes, smells, or simply hasn’t been scoped in years, call (980) 580-8641 and we’ll tell you exactly what’s going on, with camera footage you can watch yourself.

Why Emberly Chimney Cleaners Is Mercer Island’s Preferred Fireplace Services Company
Mercer Island homeowners call us because we show them the problem before we ask for a dollar. That’s not a slogan; it’s how we’ve run every job since 2009. Our background-checked, uniformed technicians arrive with a camera rig that goes down the flue, and you see the same footage we do. Corrine Halstead, who leads our team, has spent years watching how the island’s specific conditions, the canopy, the humidity, the mid-century stock, create fireplace failures that mainland shops misread or miss entirely.
We’ve completed more than 38,000 chimney inspections and cleanings under the Haven Standard, and every one of them included a written price before work started and a documented photo record when it was done. That’s Clause 1 and Clause 4 of the Haven Standard: have it in writing, and document it. When you call for a sweep or repair on Mercer Island, dispatch comes from our Seattle office and crews serve the island locally, so scheduling is straightforward.
The 365-Day Done Right Promise means if a repair fails within a year, we return and make it right. We also offer a free second opinion on any written estimate you bring us from another company. No games, no bait pricing. Just a fireplace that works the way it should.
Our Fireplace Services Services in Mercer Island
Here’s what we actually do in Mercer Island homes, week in and week out. If your issue is something else entirely, our Fireplace Services team will point you in the right direction. Every one of these starts with the camera inspection, so you know what you’re paying for before you pay for it.
Gas Fireplace Service
Gas units on Mercer Island develop specific problems: thermocouple failures from short cycling in the island’s cool damp shoulder seasons, burner ports clogged with dust that drifts in houses shaded by cedar and fir, and pilot assemblies that corrode faster in the elevated ambient humidity off Lake Washington. A full gas fireplace service, including cleaning the glass, checking the log set, cleaning the burner, and verifying gas pressure and flame pattern, runs $185-$285 in Mercer Island. If the unit needs a new thermopile or valve, you’ll see the written quote before we touch a fitting.
Wood Burning Fireplace
Older wood burning fireplaces in Mercer Island homes, especially on the original mid-century stock, have clay-tile flues that were never meant to vent modern high-temperature fires. The combination of missing tile sections, gaps in mortar joints, and the island’s damp clay that holds moisture in those liners makes these systems prone to smoke spillage and hidden creosote buildup. A full sweep and Level 2 camera inspection runs $220-$340. If the camera shows gaps or a breach, we’ll show you the footage and write up the repair options, with prices, on the spot.
Fireplace Insert
Insert installation is one of the most common requests from Mercer Island homeowners, often on homes with original masonry fireplaces that lose more heat than they produce. A properly sized insert with an insulated liner turns a leaky decorative fireplace into an actual heat source. We install inserts from brands like Gelco and Olympia Chimney, matched to the flue’s actual measurements, not guesswork. Install costs on the island run $3,200-$6,800 depending on the unit, the liner length, and the condition of the existing firebox. The written quote lists every part before you commit.
Damper Repair
A failed damper lets heated air escape up the flue year-round and lets cold Pacific Northwest air pour into the living room. On Mercer Island, we see dampers seized from rust driven by the humid microclimate and dampers warped from decades of heating and cooling. Simple damper repair or replacement runs $150-$400. If the damper seat is damaged or the chimney throat is out of square, which happens often on original mid-century construction, we’ll show you the issue and price the correct fix, usually a top-sealing damper that also helps block the needle-drop and moisture that plague island flues.
BeforeAfterTrusted Brands We Service in Mercer Island
Our techs work on most major brands, including gas inserts and wood stoves from Gelco, Olympia Chimney, and Copperfield, plus liners and components from Famco. Because Mercer Island’s housing stock trends older, a lot of what we service is original equipment, meaning parts are no longer manufactured. We stock common replacement parts for the island’s typical mid-century units, and when something isn’t on the truck, our Seattle-area supply network usually has it in a day or two. No ‘parts are backordered indefinitely’ vague answers. You’ll know the part, the price, and the arrival date.
Common Fireplace Services Problems We See in Mercer Island Homes
Mercer Island isn’t Bellevue or Renton. The island’s unique conditions, dense mature canopy, cool humid air, older housing stock, create failure patterns we see over and over:
- Hidden clay-tile flue gaps. Original mid-century chimneys built before stainless liners became standard often have missing or cracked clay tiles that vent carbon monoxide into wall cavities. These gaps are invisible without a camera. We find them on roughly a third of the unlined Mercer Island chimneys we inspect.
- Matting on north- and west-facing caps. On lots where fir and cedar hang over the roofline, chimney caps collect needles and moss so thick that airflow is restricted, pushing smoke and creosote back into the house. We’ve seen caps completely blocked on homes with otherwise clean flues.
- Damp, spalling crowns. The island’s constant drip and shade keep chimney crowns wet almost year-round. Moss infiltrates the mortar joints, the crown spalls, and water finds its way behind the flashing into roof decking. This is a slow, quiet rot that most homeowners don’t notice until a ceiling stain appears.
- Stage 2 creosote from cooler fires. Mercer Island’s humidity and the island’s habit of burning low moderate fires to take the chill off, rather than hot sustained burns, encourages glazed creosote formation. That’s the kind that ignites. It needs mechanical removal, not just brushing.

Mercer Island prices run slightly above nearby mainland cities because of travel and scheduling logistics, but the difference is modest. Here are honest ranges for our most common work on the island:

FAQs - Fireplace Services in Mercer Island
Annually, without exception. A 50-70 year-old masonry fireplace on Mercer Island with an unlined clay-tile flue is exactly the system that fails silently. The island’s humid microclimate keeps those clay tiles damp, and repeated heating and cooling creates hairline cracks that widen into gaps. Carbon monoxide seeps through those gaps into wall cavities and bedrooms. A Level 2 camera inspection once a year catches it before it becomes dangerous. If you’ve never had a camera inspection, schedule one now. Call (980) 580-8641 and we’ll book you within the week.
First-degree creosote is a flaky, black soot that a standard brush removes easily. Third-degree creosote is a hard, glazed, shiny coating that forms when flue temperatures stay low and damp, which is common on Mercer Island because of the lake humidity and the way people burn intermittent low fires. Third-degree creosote is the kind that ignites during a chimney fire, and it can’t be brushed off. It requires chemical treatment or mechanical rotary removal. If your chimney hasn’t been swept in years and you see glossy buildup on the flue walls, that’s a problem. We’ll show you the footage before and after so you see exactly what was removed.
Smoke spillage after a recent cleaning means something beyond creosote is wrong. The most common causes on the island are a blocked chimney cap matted with fir needles and moss, a flue that’s too cold due to the damp island air, or a structural problem like a missing clay-tile section that’s disrupting the draft. Some older Mercer Island fireplaces were also built with undersized flues for their firebox openings, which causes smoke to roll out the front. We fix this with a camera inspection to find the actual obstruction or draft issue, then write up the fix with a price. No more guessing.
Yes, and it’s one of the best upgrades an island homeowner can make. The conversion requires a code-compliant gas line ran to the firebox, a vented gas log set or a gas insert, and in almost every case, a properly sized stainless liner for the existing flue. On Mercer Island, the liner is non-negotiable because the existing clay-tile flue in a mid-century home is rarely sound enough for gas venting. We source log sets and components from brands like Copperfield and Gelco, write up the full parts list and labor with a firm price, and complete the conversion with a documented photo record per Clause 4 of the Haven Standard. Typical cost on the island runs $2,100-$4,500.
It matters more on Mercer Island than almost anywhere around, because the island’s tree canopy keeps crowns damp for months at a time. Moss works into the mortar joints, freeze-thaw cycles from our wet winters do the rest, and water eventually penetrates the crown to reach the flue and the roof decking below. By the time you see a water stain on the ceiling, the damage is done. We repair crowns with materials from Olympia Chimney, and we’ll show you the condition on camera before we quote. Ignoring a mossy crown is a slow, expensive leak. Call (980) 580-8641 and we’ll scope it.
