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 Alderwood Manor
If your gas fireplace won’t light, smells odd, or leaves a faint soot film on the glass, the problem usually isn’t the fireplace itself – it’s what your fireplace vents into. In Alderwood Manor, that often means a 90-year-old masonry chimney built for coal fires, not the gas log set installed decades later. Alcott Chimney Sweep repairs gas fireplaces and the chimneys they depend on throughout Alderwood Manor, from the original 1927 plat homes near the Interurban Trail to mid-century ranchers off 180th St SW. Call (336) 863-3889 and you’ll reach a live person who can schedule a repair – no voicemail, no callback queue.
Why Alcott Chimney Sweep Is Alderwood Manor’s Preferred Gas Fireplace Repair Company
Homeowners in Alderwood Manor have a specific problem that a generic fireplace shop won’t catch: their gas fireplaces vent into chimneys sized for coal. Ruben Castellano and our repair technicians understand this because we work on these exact homes every week. We know what the original 1920s clay liners look like after 95 years of Snohomish County rain – cracked, shifted, or missing entirely. That local knowledge means we don’t just replace a thermocouple and leave; we check whether the venting is actually safe.
Every technician who arrives at your Alderwood Manor home is background-checked, identity-verified, and sent to you by name and photo before the visit. They carry a photo ID badge and will show it at the door. That’s the Threshold Standard, and it’s not optional for us. Since 2002, Alcott Chimney Sweep has operated as part of the Threshold Group family of home-service companies, and we built our reputation in this region on certainty: a written price before any work begins, a written guarantee on every repair, and a free second visit if the repair fails within 365 days.
When a gas fireplace stops working in Alderwood Manor, we get there quickly. Dispatch is coordinated from our Seattle office, and our local crews serve Alderwood Manor directly – usually same week, often within a few days of your call. You’ll never be surprised by who shows up or what the job will cost.
Our Gas Fireplace Repair Services in Alderwood Manor
Our Gas Fireplace Repair team handles everything from simple pilot light issues to full venting system overhauls. Here’s what we do most often for Alderwood Manor homes:
Chimney Cap Replacement and Resealing
Winter windstorms off Puget Sound knock caps loose or send branches through them. A displaced or rusted cap lets rain pour straight down the flue, and in Alderwood Manor that water lands directly on your gas burner assembly. We replace damaged caps with properly sized stainless or copper models and reseal the crown connection so storm-driven rain stays out. If a recent storm left you with a dripping firebox or a new ceiling stain, this is the first thing we check.

Level 2 Camera Inspection for Gas Fireplace Venting
Before we recommend any gas fireplace repair in Alderwood Manor, we look inside the chimney with a camera. On a rainy March call near the original Alderwood Manor plat, a homeowner reported a ceiling stain above their gas log set. Our tech found failed step flashing at the roofline and a spalled crown letting water track down the flue; we reset the flashing, rebuilt the crown, and confirmed the gas insert was venting correctly after a Level 2 inspection. The stain dried out and the client avoided a full masonry rebuild. That’s the difference between guessing and knowing.

Chimney Crown Repair and Flashing Replacement
Alderwood Manor’s founding-era homes have masonry crowns that have absorbed 90-plus years of marine drizzle. The freeze-thaw cycles each winter spall the mortar, creating channels where water runs down into the gas firebox surround. We rebuild crowns with the right slope and overhang, and replace step flashing at the roofline using code-compliant materials. This is where most “gas fireplace leaks” in Alderwood Manor actually originate – not in the gas appliance itself.

Gas Log Set and Insert Diagnostics
Flickering flames, slow ignition, soot on the logs, or a flame that’s mostly yellow instead of blue point to a venting or gas pressure problem. We service and repair gas log sets and inserts from all major manufacturers, and because we understand the oversized coal-era flues in Alderwood Manor’s original homes, we can tell you whether the appliance is failing or the chimney it vents into is the problem. That prevents paying for a new insert when the real issue is a cracked liner.

Trusted Brands We Service in Alderwood Manor
We carry professional trade materials specified by chimney professionals, not box-store substitutes. That includes HeatShield resurfacing systems for deteriorated clay liners, Gelco chimney caps, and Olympia Chimney and Famco components. For Alderwood Manor customers, that means faster turnaround: we stock common parts locally and don’t have to special-order every repair. When a repair involves a liner, cap, flashing, or crown material, we use products built for the marine climate and decades of service – the same ones we’d install on our own homes.
Common Gas Fireplace Repair Problems We See in Alderwood Manor Homes
- Wet firebox after storms: Alderwood Manor’s wind-driven rain and persistent drizzle saturate the mortar joints and crown of 1920s – 30s masonry chimneys. Water seeps into the gas firebox surround, corroding burners and pilot assemblies. We trace the leak to its source – cap, crown, or flashing – and repair it before replacing components.
- Smoke or soot smell when the fireplace runs: On original Alderwood Manor homes, the oversized coal-era flue runs cool and slow. Modern gas inserts vent into that large space, and combustion byproducts condense inside the liner. It smells like smoke even though your gas fireplace shouldn’t produce any. A properly sized liner or resurfaced flue usually fixes it.
- Ceiling stain above the fireplace: We see this on original Alderwood Manor roofs all the time. Failed step flashing routes water behind the chimney and into the ceiling, mimicking a gas fireplace leak. Homeowners sometimes replace the insert only to find the stain returns. Before you spend on a new gas appliance, have the flashing and crown inspected.
- Pilot light won’t stay lit: In damp Alderwood Manor winters, a drafty or water-damaged chimney lets moist air push down the flue and snuff out the pilot. Thermocouples also fail from repeated exposure to moisture. We diagnose whether it’s the gas valve, the thermocouple, or the drafting environment that’s the root cause.
Pricing for Gas Fireplace Repair in Alderwood Manor, WA
You’ll get a written price before any work begins – always. In Alderwood Manor, here’s what you can expect:
- Diagnostic visit: $95 – $180, including a safety check of the gas log set, pilot, and visible venting. The fee is credited toward any repair you approve.
- Chimney cap replacement with resealing: $180 – $420, depending on cap size and material (galvanized vs. stainless vs. copper).
- Crown repair or rebuild: $350 – $900 for a standard masonry crown, depending on extent of spalling and access.
- Step flashing replacement: $450 – $1,200, depending on roof pitch, chimney size, and whether the counterflashing needs replacement too.
- Level 2 camera inspection: $200 – $400 when not paired with a repair.
- Gas log set or thermocouple repair: $120 – $350 for common replacement parts and labor.
What affects cost in Alderwood Manor specifically? The age of your home. Original 1920s chimneys on the plat or along Swamp Creek often need more extensive crown and flashing work because the masonry has weathered nearly a century of marine moisture. Postwar ranches and 1960s prefabs tend to be simpler. Call (336) 863-3889 for a free estimate – we’ll give you a real number, not a vague range, before you commit to anything.

FAQs – Gas Fireplace Repair in Alderwood Manor
A gas fireplace should not smell like smoke. If yours does, the venting is compromised – usually a cracked or missing clay liner in an original 1920s chimney, or a partially blocked flue from creosote or debris. In Alderwood Manor, the oversized coal-era flues run cool, so combustion byproducts condense inside the liner instead of exiting the chimney. We diagnose this with a camera inspection and typically fix it with a HeatShield resurfacing or liner replacement. Give us a call at (336) 863-3889 and we’ll tell you exactly what you’re smelling and what it will take to fix it.
Yes. A displaced chimney cap or cracked crown after a winter windstorm lets rain into the flue, and a waterlogged flue plus a cold, wet downdraft will often push exhaust back into the house. Your gas fireplace may still light but the flame will flicker, the smell will linger, and the pilot may repeatedly go out. In Alderwood Manor, storm-driven rain and marine drizzle make this a year-round concern, not just a December issue. Call us after any major wind event if you notice a change in how your gas fireplace burns.
Every 12 months, even if you don’t burn often. Gas fireplaces produce water vapor as a combustion byproduct, and in Alderwood Manor’s high-humidity marine climate that vapor condenses inside your chimney year-round. Combined with the area’s near-century-old masonry, annual inspection catches spalling crowns, cracked liners, and rusting caps before they become repairs. If your home is on the original 1927 plat, make it a spring appointment so any winter damage gets addressed before the next burning season.
Often, yes. A spalled crown on a 1920s Alderwood Manor chimney allows water to run down the flue and into the firebox surround, where it corrodes the burner and creates a ceiling stain below. If you see a stain above your gas fireplace, don’t replace the insert first. The crown is the most common culprit in this area, followed by failed step flashing at the roofline. Both are repairable for a fraction of what a new gas appliance costs.
First-degree creosote is a fine dust that brushes off easily. Third-degree creosote is a hard, glossy, tar-like buildup that forms when combustion gases cool too quickly – which is exactly what happens in Alderwood Manor’s oversized coal-era flues with a modern gas insert retrofitted. Gas fireplaces produce less creosote than wood, but in the wrong venting environment it still accumulates. If we find dense buildup during an inspection, we remove it and evaluate whether your flue needs resurfacing to stop it from returning. Call (336) 863-3889 if you haven’t had your chimney checked this year.
