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 Gas Fireplace Repair Across Lynnwood
Gas fireplace repair in Lynnwood usually costs between $175 and $650 for common fixes, with flue relining and crown work running higher. Most repairs take one to two hours, and we serve Lynnwood homes from the south end off Highway 99 to the hills above Alderwood Mall. If your fireplace is acting up, call Ruben Castellano’s team at Alcott Chimney Sweep at (336) 863-3889 and we’ll tell you honestly what it needs and what it doesn’t.
Lynnwood keeps us busy because the housing stock here is specific. This city incorporated in 1959 and built out fast through the 1960s and 1970s. The ranch homes and split-levels that fill neighborhoods like Martha Lake, Alderwood Manor, and the streets around Daleway Park still have their original brick fireboxes and terra cotta flue liners. Those liners are now 50 to 60 years old. When a gas insert gets vented into one of them, the math has to be checked carefully, not assumed.
Why Alcott Chimney Sweep Is Lynnwood’s Preferred Gas Fireplace Repair Company
We’ve been doing this since 2002, and in Lynnwood specifically, the pattern is consistent. Homeowners call because a gas fireplace smells, backdrafts on cold mornings, or throws a pilot light that won’t stay lit. The underlying cause often isn’t the gas valve at all. It’s the flue behind the insert, or the crown, or the flashing. We find those problems because we look for them with a camera before we quote anything.
Ruben Castellano runs Alcott with a simple rule: no recommendation without visual proof. When our technician is in your Lynnwood living room, you see what we see on the inspection monitor. If a liner is cracked, you’ll see the crack. If it’s fine, we’ll tell you it’s fine and charge you for exactly the repair you need, nothing more. That’s the kind of honesty Lynnwood homeowners tell us they rarely get from other companies.
Every technician who comes to your door is background-checked, identity-verified, and uniformed. You’ll get their name and photo before they arrive, and they’ll show a photo ID badge when you open the door. No exceptions. Our phones are answered by a live person around the clock, because a fireplace that acts up at 11 p.m. on a wet December night in Lynnwood shouldn’t send you to voicemail.
Our Gas Fireplace Repair Services in Lynnwood
Level 2 Inspection With Camera Evidence
Before we quote any Gas Fireplace Repair work in Lynnwood, we run a camera through the flue. This matters here more than in drier cities because the Puget Sound Convergence Zone pushes measurably more rainfall into the central Sound lowlands than falls on Edmonds or Mukilteo. That moisture works its way into 60-year-old masonry and hides damage you can’t see from the firebox. A Level 2 inspection is the only way to know whether the original terra cotta liner is still safe to vent a gas insert into.
Flue Liner Evaluation and Relining
Gas inserts in Lynnwood homes are frequently vented into original clay tile flues that were never sized or designed for gas appliances. That mismatch causes condensation, which breaks down mortar joints over time. We evaluate the existing liner, show you the camera footage, and if relining is needed, we install HeatShield or DuraFlex systems sized to the insert. Not every cracked liner means a full rebuild. We’ve relined flues in Lynnwood homes with a HeatShield-cast liner and restored proper draft without tearing out a single brick.
Chimney Crown and Flashing Repair
Convergence Zone moisture saturates chimney crowns and flashing in Lynnwood year after year. When a crown cracks, water gets into the masonry, freezes, thaws, and spalls brick and mortar. That damage shows up as white staining on the chimney face outside, or as a draft problem on cold mornings inside. We repair crowns with proper slope and sealant, and replace flashing that’s let go around the flue. This isn’t a cosmetic fix. It’s what keeps exhaust and moisture from migrating into your wall cavity.
Gas Log Set and Pilot Assembly Repair
Sometimes the problem really is the appliance. We service gas log sets, pilot assemblies, thermocouples, thermopiles, and valves from the brands Lynnwood homes actually have: Famco and Copperfield being the most common. But even when we’re replacing a thermopile, we look downstream at the flue first. A gas fireplace that won’t stay lit often has a draft problem behind it, and replacing the thermopile without checking the flue is a waste of your money.

Common Gas Fireplace Repair Problems We See in Lynnwood Homes
- Gas inserts vented into unlined or single-wythe terra cotta flues. Homes built in the 1960s around Martha Lake and Alderwood Manor were designed for open wood fires, not sealed gas exhaust. The original clay tile liners can’t always handle the moisture and temperature profile of a gas insert, and the result is condensation that turns mortar to powder. This gets misdiagnosed as a bad insert constantly.
- Cracked liners from freeze-thaw cycles. The Convergence Zone means Lynnwood chimneys go through more saturation and freeze cycles than chimneys in Edmonds or Mukilteo. A hairline crack from 1970 becomes a visible gap after fifty wet winters. Gas exhaust then leaks through that crack into the wall cavity instead of venting outside.
- Glazed creosote left behind from the wood-burning years. A lot of Lynnwood fireplaces burned wood for decades before a gas insert went in. That old creosote is still there, hidden behind the insert. If it’s the hard, shiny stage-three variety, standard brushing won’t remove it. It needs chemical treatment before any gas fireplace repair is trustworthy.
- Pilot lights that won’t stay lit on cold, damp mornings. Cold air sinks into the flue overnight, especially on those wet Pacific Northwest mornings. If the liner has a gap or the chimney isn’t drafting properly, that cold plug pushes exhaust back into the living room. The symptom looks electrical. The cause is usually the flue.

FAQs – Gas Fireplace Repair in Lynnwood
Not without checking the flue first. The terra cotta liners in Lynnwood’s 1960s and 1970s ranch homes are now 50 to 60 years old, and many have cracks or deteriorated mortar joints from decades of Convergence Zone moisture. Venting a gas insert into a damaged liner can push exhaust into your wall cavity. A camera inspection tells you in 30 minutes whether your flue is safe to use. Call (336) 863-3889 to schedule one.
Cold air sits in the flue overnight, and on cold, damp Lynnwood mornings, that air plug pushes exhaust back into the living room instead of letting it vent outside. The root cause is usually a gap in the liner or a draft problem in the chimney, not the gas appliance itself. We diagnose it with a camera and fix what’s actually wrong.
Yes, and it’s almost certainly left over from the years when that fireplace burned wood. Stage-three glazed creosote is hard, shiny, and won’t come off with standard brushing. It has to be chemically treated before any gas fireplace repair can be considered complete. Leaving it in place behind a gas insert is a hidden fire risk. We can show you photos from the camera before we recommend treatment.
No. In most cases we reline the flue with HeatShield or DuraFlex, which is installed from the firebox or the top of the chimney without removing a single brick. We’ve done this repeatedly in Lynnwood’s 1960s split-levels, where a cracked terra cotta liner doesn’t mean the whole chimney is condemned. The only way to know is with a camera inspection.
Every year, before burning season starts in October. Lynnwood’s burning season runs October through April, and the high ambient humidity here accelerates creosote conversion and mortar breakdown. An annual inspection catches small problems before they become expensive ones. If it’s been more than a year, call (336) 863-3889 and we’ll get you on the schedule.
On a 1968 split-level off 196th St SW near Lynnwood High, our technician pulled a gas log set and found the original terra cotta flue liner had a hairline crack and spalled mortar at the smoke chamber. The homeowner saw it on our inspection camera before we touched anything else. We ran a Level 2 inspection, showed the footage, and relined the flue with a HeatShield-cast liner sized for the insert. We didn’t sell a full rebuild, because the chimney didn’t need one. That insert has run clean through three winters since. That’s how we work in Lynnwood: show the proof, do the right repair, write it all down.
