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.
Fast, Reliable Gas Fireplace Repair Across Kenmore
Gas fireplace repair in Kenmore typically runs $145 – $425 for most service calls, and the work usually takes under two hours once we’re on site. We cover the whole city: the hillside streets above NE Bothell Way, the Sammamish River corridor, the neighborhoods around Kenmore Elementary and Inglemoor High, and everything in between. Our crews keep parts for the most common gas log sets and fireplaces on the truck, so a single visit solves most problems. Call (336) 863-3889 and you’ll get a live person, a straight answer, and a written price before anyone starts working.
Why Alcott Chimney Sweep Is Kenmore’s Preferred Gas Fireplace Repair Company
Kenmore’s housing stock is specific, and so are the failures we fix here. This city was built out in the 1950s through 1970s, which means most homes have original brick chimneys now hitting 50 to 70 years old. Ruben Castellano runs our crews with a simple rule: diagnose the real problem, show the customer the evidence, and write the price before any tool comes out. We don’t recommend work you can’t see for yourself.
Every Alcott technician is background-checked and identity-verified under the Threshold Standard before they ever set foot on a Kenmore driveway. You’ll get the technician’s name and photo before we arrive, and they’ll show a photo ID badge at the door. No exceptions, no substitutes. That matters to people here, and it should.
Our Gas Fireplace Repair crews know Kenmore’s damp Sammamish River basin and what it does to gas appliances. A unit that sat unused all summer can still show up with a rusted burner pan in October. We don’t treat that as a surprise; we expect it.
Our Gas Fireplace Repair Services in Kenmore
Gas Fireplace and Log Set Service
Most gas fireplace calls in Kenmore start with three symptoms: a lazy yellow flame, soot building up on the logs, or an odor that won’t clear even after the unit runs for a while. We pull the log set, inspect the burner pan and ports, clean what needs cleaning, and replace what’s failed. On the damp streets near the Sammamish River, we routinely find burner pans rusted from moisture wicking through aging single-wythe brick. Re-setting a log set on a new Gelco burner assembly is a common fix here, and it’s one we stock parts for locally.

Chimney Crown and Flashing Repair
Cracked crowns and failed flashing let water into the stack year-round, but in Kenmore the problem compounds fast. The city’s low position between Lake Washington and the Sammamish River keeps masonry damp for longer stretches than in upland King County suburbs, and that water works its way down to the firebox throat. We repair crowns with a proper bond break and flexible sealant, replace step and counter flashing where needed, and make sure the stack sheds water instead of absorbing it.

Masonry Waterproofing
Waterproofing in Kenmore is not an upsell. It’s the difference between a chimney that lasts another 20 years and one that spalls bricks onto the lawn. We apply vapor-permeable masonry sealers that let the brick breathe while blocking liquid water. In lower-lying neighborhoods near the floodplain, we recommend this on nearly every stack we touch, because the local ground fog and high water table mean the masonry is rarely dry enough on its own to stop capillary wicking.

Gas Insert and Liner Assessment
Many Kenmore homeowners assume a gas insert means the chimney is fine. It’s not always true. If the original clay flue liner has cracked from decades of moisture cycling, exhaust and condensation can spill around the insert instead of drafting clean. We scope the flue with a camera and show you what we see. If the liner is intact, we say so. If it’s not, you’ll get photos and a written quote before anything is recommended.

Trusted Brands We Service in Kenmore
We stock parts for the gas appliances most common in Kenmore homes, and we install what we trust. That means Olympia Chimney caps and dampers, Famco venting components, and Gelco burner assemblies. No box-store substitutes. When your gas log set needs a new burner pan or thermocouple, we usually have the right part on the truck, which means fewer trips back and a shorter time without heat.
Common Gas Fireplace Repair Problems We See in Kenmore Homes
- Rusted burner pans from chronic moisture. Kenmore’s ground fog and damp corridor air wick into original single-wythe brick, and that moisture works its way to the firebox throat. We’ve pulled gas log sets in July that looked like they’d been sitting in a puddle all winter.
- Cracked clay flue liners in 1950s – 70s stacks. Decades of moisture cycling crack the original clay tiles. A gas insert doesn’t protect the liner; a cracked liner still lets exhaust and condensation spill where it shouldn’t go.
- Moss and lichen on crowns and shoulders. The damp microclimate around Lake Washington feeds aggressive moss growth on chimney tops. Moss holds water against masonry, which accelerates spalling and works into cracks.
- Lazy flames and clogged gas ports. Rust particles and mineral scale from moisture moving through the brick face clog the small ports where gas exits the burner tube. A weak, yellow flame with heavy soot is a telltale sign.

FAQs – Gas Fireplace Repair in Kenmore
The damp smell comes from moisture wicking through your chimney’s masonry and reaching the firebox throat. In Kenmore’s low-lying Sammamish River corridor, the ground fog and high water table keep that masonry wet even in July, and the smell lingers because the unit isn’t hot enough to drive the moisture off. We fix this by sealing the crown and flashing and waterproofing the masonry so water stops entering the stack. Call (336) 863-3889 to have us diagnose yours.
Yes. A gas-only chimney still needs a Level 2 inspection before you switch to gas or when you buy a home. The original clay liner can crack from moisture cycling without anyone noticing, and a cracked liner means exhaust and condensation can spill around the insert. We scope the flue with a camera so you see exactly what we see. If the liner is sound, you’ll know it. If it’s not, you’ll have photos and a written quote before any repair is recommended. Call (336) 863-3889 to schedule.
Every six months. A wood stove used as the primary heat source in Kenmore burns roughly four to six cords a season, and if that wood is even partially seasoned (common around here, given the damp sheds), it produces heavy second-degree creosote faster than in drier inland markets. The heating season runs effectively October through April, which is a long time to push creosote up the flue. A mid-season sweep in January keeps the system working safely when you need it most. Call (336) 863-3889 to book before the cold sets in.
Possibly. Original clay liners in 1950s – 70s Kenmore ranches are now 50 – 70 years old, and decades of damp-corridor moisture cycling cracks them. A gas insert doesn’t protect that liner; if it’s cracked, exhaust and condensation can spill around the insert instead of drafting clean. We scope the flue with a camera before recommending anything. In some cases the liner is fine and you can proceed. In others, a DuraFlex liner system is the right fix. You’ll see the evidence either way. Call (336) 863-3889 for a camera inspection.
Yes, measurably so. The low basin at the northern tip of Lake Washington and along the Sammamish River corridor traps ground fog and holds higher humidity than in upland Woodinville or Sammamish. That means Kenmore masonry stays wet for longer stretches, moss grows faster, and water wicks into fireboxes even in summer. A crew was out on a gas log set in a 1962 split-level off NE Bothell Way near the floodplain where the customer had a lazy flame and a firebox that smelled damp with the logs off all summer. We found the burner pan rusted from chronic moisture, replaced it with a Gelco assembly, and sealed the crown, flashing, and shoulders. Same unit in Woodinville probably wouldn’t have rusted that fast. That’s the difference. Call (336) 863-3889 and we’ll tell you what your stack needs.
