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 Keene
Gas fireplace repair in Keene typically runs $145 – $685, with most common fixes like thermocouple replacement or pilot assembly service falling between $180 and $340. We schedule repairs across Keene Monday through Friday and Sunday, because a large share of this community observes Sabbath from Friday sundown to Saturday sundown, and we respect that rhythm. If your gas logs won’t light, the flame keeps dying, or the blower stopped running, call (336) 863-3889 and a live person picks up. Ruben Castellano and our team have been repairing gas fireplaces since 2002, and we approach every Keene job the same way: no repair gets recommended until you’ve seen the camera footage yourself.
Why Alcott Chimney Sweep Is Keene’s Preferred Gas Fireplace Repair Company
Keene isn’t a typical Johnson County town, and we don’t treat it like one. We already know that a gas log set sitting dormant through two mild winters then getting fired hard during an ice storm will crack a clay-tile flue faster than anything else. That’s the local failure pattern, and we plan our diagnostics around it. We also know that many homes near Southwestern Adventist University were built in the 1950s and 1960s with original masonry fireplaces never designed for gas appliance exhaust at all. When a Keene homeowner calls us because a gas insert is drafting poorly, we start from that foundation of local housing reality, not a generic service script.
Every technician we send to Keene has passed a background check and identity verification through the Threshold Standard. You’ll get the technician’s name and photo before the truck leaves our dispatch, and that same person will show a photo ID badge at your door. No exceptions. Our written price is delivered before any work starts, and our 365-Day Done Right Promise means every gas fireplace repair we complete carries a written guarantee. If the repair fails within that window, the second visit is free.
Our Gas Fireplace Repair Services in Keene
Gas Fireplace Flue Liner Inspection and Replacement
Older Keene homes with original masonry chimneys almost always have clay-tile flue liners, and those tiles were sized for wood smoke, not the cooler, wetter exhaust from a gas log set. The result is condensation that eats mortar joints and eventually cracks the tile. We run a Chimney Inspection - Keene with a Level 2 camera before touching anything, then we show you the footage. If the liner is compromised, we install HeatShield or DuraFlex systems sized specifically for your gas appliance’s exhaust volume, not whatever is on the truck.
Firebox and Damper Repair for Aging Masonry Fireplaces
Johnson County’s shrink-swell clay soil has been shifting the ground under Keene’s mid-century homes for decades. That movement cracks chimney crowns and opens mortar joints, and rain gets into the firebox, where it rusts dampers and gas burner assemblies. We repair firebox panels, rebuild rusted dampers, and reseal crowns on these older stacks regularly. A rusted damper that won’t open is both a draft problem and a carbon monoxide concern when gas logs are burning. We don’t guess at it, we put the camera in and look.
Level 2 Camera Inspection Documented Before Any Repair
Here’s what you won’t get from us: a phone quote for a $4,000 liner replacement based on nothing but the age of your house. We run a camera inspection of the entire flue, firebox, and smoke chamber, then we bring the tablet to your kitchen table. You’ll see exactly what we see before a single repair is recommended. If the flue is clear and the gas log set just needs a thermocouple, that’s what we tell you. If the clay tiles are cracked and spalling, you’ll see the cracks in high definition, and then we’ll talk about your options.
Pilot Assembly, Thermocouple, and Burner Service
Most gas fireplace service calls in Keene are the same handful of issues: a pilot that won’t stay lit, a weak orange flame, a blower that hums but won’t turn, or soot building up on the glass faster than it should. We stock common pilot assemblies, thermocouples, and burner parts to keep turnaround fast. If a part has to be ordered, you’ll know the price and the timeline before we leave the first visit.

Trusted Brands We Service in Keene
We carry and install professional trade materials, not box-store substitutes. That means HeatShield resurfacing systems for compromised flue liners, Gelco chimney and fireplace components, Famco dampers and caps, and Olympia Chimney products where they fit the application. When a Keene fireplace needs a part, we’d rather wait a day for the right component than install something approximate. We service all major gas log set brands and vented and vent-free configurations commonly found in Keene homes. Gas Fireplace Repair is a core service for us, not a side line, and our parts inventory reflects that.
Common Gas Fireplace Repair Problems We See in Keene Homes
- Dormant-then-overfired flue cracks: A gas fireplace that sits unused for two mild winters, then gets fired hard during a February ice storm, subjects an aging clay-tile flue to thermal shock. We see the resulting hairline cracks regularly in Keene homes, and they’re invisible without a camera inspection.
- Foundation-movement chimney damage: Johnson County’s shrink-swell clay soil keeps shifting under older masonry stacks. That opens mortar joints and cracks crowns in neighborhoods throughout Keene, letting rain into the firebox where it rusts dampers and burner assemblies.
- Chimney swift roosts blocking service: From roughly April through October, uncapped chimneys in Keene are prime swift roosting habitat. We scope every flue before booking a repair during those months, because a repair legally cannot proceed until federally protected birds have migrated out.
- Gas logs installed in flues built for wood: Many mid-century Keene fireplaces were built for wood burning, with oversized flue tiles that cool gas exhaust too quickly. That creates weak draft, flame roll-out, and condensation that accelerates masonry deterioration.

FAQs – Gas Fireplace Repair in Keene
We don’t book Saturday service calls in Keene because a large share of this community observes Sabbath from Friday sundown to Saturday sundown, and we’ve structured our entire local scheduling around that reality. Repairs are available Monday through Friday and on Sunday. Call (336) 863-3889 and we’ll find a window that works with your household’s rhythm.
Yes, but the flue has to be evaluated first. Many original clay-tile flues in mid-century Keene homes were sized for wood smoke and are oversized for gas exhaust, which can cause condensation and weak draft. We run a camera inspection, show you the footage, and if the liner needs resizing or repair we’ll install a HeatShield or DuraFlex system sized for your specific gas appliance, not a one-size-fits-all liner. Estimates for the repair are written down and free.
Chirping in August usually means chimney swifts, which are federally protected under the Migratory Bird Treaty Act. If they’re roosting in your flue, we legally cannot remove them or perform work that disturbs them until they migrate out in fall. We’ll confirm with a camera scope and book your gas fireplace repair for when the flue is clear. Call us and we’ll check it before you spend another evening listening to the chorus.
It could be either, and guessing wastes your money. A flame that lights then rolls and dies often points to weak draft, which can be a blocked flue, a cracked clay tile, or an oversized liner cooling the exhaust too fast. It can also be a failing thermocouple or a clogged burner. The repair starts with diagnostics, and you’ll see whatever we find. Call (336) 863-3889 for a free estimate on the service call.
Yes. Gas fireplaces still produce carbon monoxide and still vent it through the flue. A blocked, cracked, or deteriorated flue in a Keene home can vent combustion gases into the living space instead of outside. That’s not a scare tactic, it’s what the camera shows. A Level 2 inspection also catches the rust, mortar failure, and swift nests we see in mid-century Johnson County stacks. If the flue is clear, we’ll tell you so plainly and you won’t be sold a repair you don’t need.
