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.

Why Alcott Chimney Sweep Is Sultan’s Preferred Gas Fireplace Repair Company
Since 2002, our team has worked on chimneys up and down the Highway 2 corridor, and Sultan has always had its own personality. We know the difference between a genuinely blocked flue and a Skykomish valley inversion that mimics one, and that knowledge keeps Sultan homeowners from paying for work they don’t need. Every technician who arrives at your door is background-checked and identity-verified under the Threshold Standard, and you’ll receive their name and photo before we dispatch. No stranger-at-the-door surprises, ever. That matters in a town where many people live on acreage, often home alone, and want certainty about who’s walking up the driveway.
We’re part of the Threshold Group family of home-service companies, and the vetting isn’t optional. Our techs show a photo ID badge when they arrive. The price is written before any work starts. Every repair carries a written guarantee, and if that repair fails within the coverage period, the second visit is free. It’s a 365-Day Done Right Promise, and it’s how we’ve earned trust from homeowners in Sultan, Startup, and the surrounding valley communities.
Our Gas Fireplace Repair Services in Sultan
Gas Fireplace Insert Draft and Venting Diagnostics
This is the service Sultan homeowners need most, because of how this valley behaves. On still, cold winter mornings, dense air pools in the Skykomish valley and pushes down chimneys, reversing draft and sending exhaust back into the firebox. We diagnose this with a manometer before recommending any work. If the draft is genuinely compromised by a liner or block, we’ll show you the camera evidence. If it’s inversion, we’ll tell you that too, and often the fix is a correctly sized cap or minor adjustment, not a rebuild.
Many Sultan homes have gas inserts vented into chimneys originally built for coal stoves. Those flues are often 8×12 or larger, and a modern gas insert needs a 4 or 5 inch liner to maintain proper draft velocity. We diagnose, explain what we’re seeing, and quote only what the camera verifies.
Flue Liner Replacement and Sizing for Gas Appliances
Older Sultan chimneys frequently have clay-tile liners cracked by decades of freeze-thaw cycles. The valley gets significantly more precipitation than lowland Snohomish County, and water that seeps into those cracked tiles freezes and spalls them further. Once a liner is compromised, gas appliance exhaust can leak into the smoke chamber or attic instead of drafting up the stack. We reline using DuraFlex stainless systems sized correctly for your specific appliance. A typical liner replacement in Sultan runs $1,800 – $3,400 depending on flue height, accessibility, and whether we’re replacing a clay liner or lining an unlined original brick stack.
Mortar Repointing and Chimney Crown Repair on Aging Brick Stacks
Walk down Main Street or along Ben Howard Road and you’ll see it: original brick chimneys from Sultan’s logging and railroad era, built in the 1920s through 1940s, with mortar joints eroded by wet Pacific Northwest weather. When mortar fails, water gets behind the brick, freezes, and pushes sections loose. We repoint with professional-grade materials and repair crowns to stop water intrusion before it destroys the firebox and damper assembly that your gas fireplace depends on. Repointing in Sultan typically runs $15 – $28 per square foot of face.
Gas Fireplace Inspection and Camera Verification
Before anything gets quoted for repair, we run a Level 2 camera inspection through the flue. You’ll see exactly what we see, on our screen, in real time. If we recommend a liner or mason work, you’ll have photos and video to back it up. That’s the threshold for any repair recommendation at Alcott Chimney Sweep, and we won’t budge from it. Sultan homeowners deserve to see the evidence before spending thousands, and we make that standard practice on every job.

Trusted Brands We Service in Sultan
We service and install equipment from the brands chimney professionals actually specify, not box-store substitutes. That includes HeatShield resurfacing systems for damaged clay flues, Gelco caps and chase covers, Olympia Chimney liners and components, and Famco venting products. Because we stock common parts for gas inserts and fireplaces at our regional warehouse, we can often complete repairs in a single visit rather than ordering and waiting on parts. For Sultan customers, that means less time without heat during the long burn season, and fewer days coordinating a second appointment.
Common Gas Fireplace Repair Problems We See in Sultan Homes
- Pilot lights that won’t stay lit on cold mornings. In Sultan, this is often misdiagnosed as a thermocouple or thermopile failure when the real culprit is valley cold-air pooling reversing the draft and starving the pilot of oxygen. We test draft first, then electronics, so you don’t pay for a part that wasn’t the problem.
- Sooting glass and firebox walls within minutes of ignition. When a gas insert is vented into an oversized coal-era flue, exhaust cools too quickly and condenses on the glass instead of drafting out. This typically calls for a correctly sized liner, and we’ll show you the camera footage proving it before we quote the work.
- Faint gas or exhaust odor inside the house. Cracked clay-tile liners and failed mortar joints let combustion gases leak into the smoke chamber or wall cavities instead of venting up the stack. This can happen in Sultan homes even when the fireplace seems to work fine, because slow leaks aren’t always visible from the firebox. If you smell this, call us and stop using the fireplace until we’ve inspected it. Gas exhaust contains carbon monoxide, and a chimney leaking into your home is a safety issue that needs a trained professional, not a DIY patch.
- Water staining around the fireplace or ceiling near the chimney chase. Valley rain works through failed crowns and flashing, and in older Sultan homes the water often travels down inside the chimney before it shows up anywhere you can see it. By the time you spot the stain, the damper and firebox may already have rust damage. We inspect the full stack from top to firebox and give you a written report with photos.
Pricing for Gas Fireplace Repair in Sultan, WA
Here’s what Sultan homeowners can expect to pay for common gas fireplace repairs:
- Diagnostic visit with camera inspection: $129 – $189 (waived when you proceed with repair)
- Pilot assembly or thermopile replacement: $185 – $340
- Gas valve replacement: $275 – $510
- Burner or log set replacement: $230 – $480

- Mortar repointing on an original brick stack: $15 – $28 per square foot
- Chimney crown rebuild or seal: $425 – $980
Several things move the price in Sultan specifically. Roof pitch and chimney height on older two-story wood-frame homes mean more ladder and staging time. Water damage inside the stack from valley rain often means additional sealing or liner work beyond the obvious repair. And if your gas insert needs a liner resize, that’s a bigger job than a simple part swap. You’ll get a written quote before anything starts, and that quote doesn’t change unless you approve a change first. Call (336) 863-3889 for a free estimate.

FAQs – Gas Fireplace Repair in Sultan
On still winter mornings in Sultan, cold dense air pools in the Skykomish valley and creates negative draft that pushes exhaust back down the chimney and snuffs out the pilot. This is an inversion condition, not necessarily a blockage. We diagnose it with a manometer to see what the draft is actually doing before recommending any work. If it’s inversion alone, the fix may be a properly sized cap or minor venting adjustment, not a rebuild. If it’s a blocked or damaged flue, you’ll see the camera evidence. Call (336) 863-3889 and we’ll sort out which one it is.
Yes, and we won’t quote a liner or masonry repair without camera evidence you can see for yourself. Sultan has a lot of early-to-mid 1900s wood-frame homes with original brick stacks, and the damage inside those chimneys is invisible from the firebox. We run a Level 2 camera inspection, show you the footage, and give you a written report before any repair quote. If a chimney company quotes you a rebuild without putting a camera up the flue, get a second opinion.
Only if it’s been relined with a correctly sized stainless liner. Original coal-era flues in Sultan homes are often 8×12 or larger, far too wide for a modern gas insert to maintain proper draft velocity. Worse, decades of valley freeze-thaw cycles have cracked many of those clay-tile liners. We reline with DuraFlex stainless sized precisely to your insert’s venting requirements, and we seal the smoke chamber so exhaust drafts up the stack instead of leaking into the house. A liner replacement is the difference between a fireplace that works and one that soots up, snuffs out, and potentially leaks carbon monoxide.
In Sultan specifically, we see two patterns over and over. First, clay-tile liners cracked and spalled by wet, freezing valley weather, letting gas exhaust and moisture leak into the smoke chamber and attic. Second, accelerated mortar deterioration from the same freeze-thaw cycling, which lets rain into unlined flues and rusts out dampers and firebox assemblies. Creosote itself is more of a wood-burning concern, but when Sultan homeowners burn both wood and gas through the same stack, the combination of heavy creosote and a cracked liner is exactly what starts chimney fires. That’s why we inspect the full stack, not just the visible firebox.
Because Sultan’s weather is working on your chimney even when you’re not using it. Valley rain seeps into cracked mortar and failed crowns, freeze-thaw cycles spall brick faces and flue tiles, and cold-air pooling stresses draft every winter night whether the fireplace is lit or not. A gas fireplace that sits idle all season still has a vent connected to your home’s interior. If that vent is compromised, you have a slow leak of combustion gases or a moisture problem you can’t see. An annual Level 1 or Level 2 inspection catches it early, before a $300 repair becomes a $3,000 reline. Call (336) 863-3889 to schedule yours.
How the Skykomish Valley Changes Gas Fireplace Repair
Sultan sits deep in the Skykomish River valley at the foot of the Cascades, where annual precipitation is significantly higher than in lowland Snohomish County. The valley’s cold-air pooling on still winter nights is a real, documented condition, not a guess. When dense cold air settles into the valley floor, it pushes down on chimneys and reverses natural draft. Homeowners here misdiagnose this as a dirty chimney or a failing gas valve far more often than in open-terrain towns like Monroe just twelve miles west. We bring a manometer to every Sultan gas fireplace diagnostic because we already know the valley is working against your venting. That’s a step other companies skip, and it’s why our Gas Fireplace Repair in Sultan diagnostics catch what a parts-swapper misses.
Then there’s the housing stock. Sultan’s origins as a Skykomish valley logging and railroad town mean a notable share of early-to-mid 1900s wood-frame homes still standing with their original brick masonry chimneys. Those stacks were built for coal stoves and wood burners, not sealed-combustion gas inserts. The flue diameters are wrong for modern appliances, and decades of wet Pacific Northwest weather have eroded the mortar and cracked the tiles. When you combine an oversized flue with a valley inversion, you get chronic drafting failure that no amount of cleaning will fix. The fix is a correctly sized liner and a sealed smoke chamber, verified by camera before and after.
We were called to a 1920s wood-frame home off Main Street in Sultan, where the homeowner reported their gas fireplace insert kept snuffing out and sooting the firebox within minutes of ignition. A Level 2 inspection with our camera showed the original clay-tile flue liner was spalled and oversized for the insert, allowing cold valley air to reverse the draft. We relined the stack with a correctly sized DuraFlex liner, sealed the smoke chamber, and the insert now lights and holds without a hitch. That’s the sequence we follow on every Sultan gas fireplace job: diagnose the draft, show the camera evidence, size the liner, and verify it’s right.
