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.

In most cases, we can have a background-checked, identity-verified technician at your Kent door within a day or two of your call. Ruben Castellano and our team know exactly what Kent’s damp valley air and 1980s prefab construction do to gas fireplaces, and we’ll give you a written price before any work begins.

Why Alcott Chimney Sweep Is Kent’s Preferred Gas Fireplace Repair Company
We built our reputation in Kent on something simple: showing up when we say we will, as the person we said would show up. Every Alcott technician is background-checked and identity-verified under the Threshold Standard before they ever step onto a Kent driveway. You’ll get the technician’s name and photo before the visit, and they’ll show a photo ID badge at the door. Kent homeowners tell us that’s the reason they choose us over the nameless outfits. We don’t send a stranger to your house.
Our work in Kent runs on written guarantees, not handshakes. Every Gas Fireplace Repair we complete in Kent includes a written guarantee at no extra charge. If the repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to every job we do from East Hill to the valley floor. Ruben Castellano backs that promise personally, and it’s why so many Kent customers call us first when their fireplace acts up.
We also understand that gas fireplace problems in Kent are rarely just about the gas. The Green River Valley’s winter inversions, the damp air that never quite dries, and the sheer number of 1980s prefab units on East Hill mean gas fireplace repair in Kent often involves water intrusion, shared flue stacks, and draft problems that a generic fireplace company in Seattle won’t diagnose correctly. We do, because we see them every week.
Our Gas Fireplace Repair Services in Kent
Gas Fireplace Troubleshooting and Repair
Most calls we take from Kent start with a fireplace that lights and then dies, or flames that roll out of the firebox instead of rising cleanly. On Kent’s East Hill, especially near Kent-Kangley Road and the denser zero-lot-line neighborhoods, we frequently trace these symptoms back to draft suppression. The valley’s cold-air inversions trap a bubble of dense air over Kent that fights the chimney’s natural draw. A fireplace that works fine on a mild afternoon can backdraft by morning. We diagnose the whole system, not just the gas valve.

Chase Cover Replacement and Flashing Repair
The most common repair we perform on Kent’s East Hill is a chase cover replacement. The original stamped-steel covers on 1980s prefab fireplaces rust through after 30-plus years of Kent’s rain and fog. Homeowners never see it because the cover sits hidden under a steep roofline. Water drips onto the firebox for years, rotting framing and causing erratic ignition. We fabricate and install proper metal chase covers, seal the flashing, and stop the water for good.

Level 2 Inspection with Shared-Flue Camera Scan
Kent’s attached and zero-lot-line housing stock creates a problem most fireplace companies never look for: shared or adjacent flue stacks. When a neighbor’s gas appliance vents into the same stack, their exhaust can push into your firebox, especially during winter inversions. Our Chimney Inspection - Kent includes a Level 2 camera scan specifically checking for shared-flue conditions, cross-ventilation damage, and creosote glaze inside the liner. We’ll show you the video and explain exactly what we saw.

Firebox and Refractory Panel Replacement
The factory-built fireplaces that dominate Kent’s East Hill use refractory panels that crack and crumble after decades of heat cycling. Once panels fail, the firebox loses its insulation and can overheat the surrounding framing. We replace failed panels with professional-grade materials, never box-store substitutes. If your Kent fireplace is 25 years or older and hasn’t had the panels checked, this is the first thing we’ll inspect.

Trusted Brands We Service in Kent
We service and install the brands found in Kent’s 1970s through 1990s tract homes, so we stock the parts that matter locally. If your prefab unit needs a new Famco cap or a Copperfield termination kit, we typically have it on the truck. For liner repairs we use DuraFlex systems, the same specification chimney professionals across the Pacific Northwest specify. We don’t improvise with whatever the hardware store happens to carry. When a HeatShield resurfacing is the right call for a Kent masonry chimney, we’ll explain the process plainly, show you the before-and-after scope video, and give you a written price before we begin.
Common Gas Fireplace Repair Problems We See in Kent Homes
- Backdrafting through shared or adjacent flue stacks: East Hill’s dense, zero-lot-line housing means your gas fireplace may share a chase with a neighbor’s appliance. During valley inversions, their exhaust can push into your firebox and fill the room with a smell that doesn’t belong to your unit.
- Rusted-through chase covers on 1980s prefab units: Kent’s 38 to 40 inches of annual rain, frequent ground fog, and hidden roofline covers mean water has been getting into thousands of East Hill fireboxes for years. The symptom is a fireplace that lights erratically or flames that roll out.
- Third-degree creosote glaze in the liner and smoke chamber: Pacific Northwest alder and Doug fir stored in damp Kent garages never fully season, and those low-burn smolders deposit the hardest creosote glaze. Even in a gas fireplace, residual glaze in a shared flue causes draft and odor problems.
- Wet mortar and spalling in valley-floor masonry chimneys: Older homes near downtown Kent and along the Green River valley floor have masonry chimneys whose mortar joints absorb chronic moisture. Spalling bricks and cracked crowns let water soften the flue from the inside, causing flaking and blockages.

FAQs – Gas Fireplace Repair in Kent
Yes, and we see this regularly in Kent’s East Hill neighborhoods where 1980s zero-lot-line housing shares flue chases. Valley inversions suppress draft, and a neighbor’s exhaust can backdraft into your firebox through a shared stack. The fix usually involves sealing the shared termination with a proper cap and re-setting the damper so your unit drafts independently. Call (336) 863-3889 for a camera scan that will confirm it in one visit.
Once a year. Kent’s damp air works on your fireplace 12 months a year, not just during burn season, and rusted chase covers on East Hill prefab units leak water even when the gas is off. An annual inspection catches the water intrusion before it rots your framing. Most Kent homeowners schedule it in late summer so they’re ready for the first cold snap.
A chase cover is the metal lid on top of the framed structure that encloses your prefab fireplace flue. The original stamped-steel covers on Kent’s 1980s tract homes rust through after 30-plus years of our rain and fog, and because they sit hidden under steep East Hill rooflines, homeowners never see the damage until water has already reached the firebox. We replace them with proper metal covers and seal the flashing. A typical replacement in Kent runs $450 to $900.
Flame rollout in a Kent gas fireplace is almost always a draft problem, not a creosote problem. When valley inversions suppress the chimney’s draw, the flame can’t pull upward and rolls out toward the room. In East Hill’s attached housing, a neighbor’s appliance in a shared flue stack can also cause it. This is a safety issue. Call (336) 863-3889 and we’ll diagnose the draft immediately.
Yes. We service and install Famco, Copperfield, DuraFlex, and HeatShield components, the same brands specified in Kent’s older prefab and masonry units. We typically stock the common parts on the truck, so many repairs are completed the same day. If your unit needs a specific termination kit or liner component, we’ll have it ordered and installed within the week.
