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.

Our crews work throughout St. Helena, from the grand Victorians on Main Street to the hillside estates off Spring Mountain Road and Howell Mountain Road. We know these chimneys, the 1880s brick stacks with flues that were never relined, the modern luxury homes with three or four hearth systems, and the outdoor fireplaces that get heavy use from September through November. When a gas fireplace in St. Helena won’t light or smells off, the cause is often the chimney, not the gas valve, and that’s exactly what our Gas Fireplace Repair team is trained to find.

Our Gas Fireplace Repair Services in St. Helena
Here’s what we actually do in St. Helena homes, and why each service matters for this specific market.
Level 2 Camera Inspection with Homeowner-Visible Evidence
In St. Helena’s pre-1900 brick homes, you should never approve a chimney recommendation without seeing it yourself. Our Chimney Inspection - St. Helena includes a Level 2 camera run through the full flue, and we show you the footage on the spot. If we find a breached clay tile or spalling mortar in the smoke chamber, you’ll see it on the screen before we discuss any repair. We won’t recommend a liner, a cap, or anything else without camera evidence you can watch with your own eyes. This matters enormously in St. Helena, where original brick chimneys on and around Main Street have frequently never been relined, and where the industry’s worst upselling happens precisely because homeowners can’t see inside their own flue.
Gas Fireplace Service and Ignition Troubleshooting
Wind-blown ash and ember debris from the Glass Fire corridor lodges in chimney caps and air intakes of hillside estates throughout St. Helena. The result is a weak flame, sooting on the glass, and repeated pilot outages that get misdiagnosed as a bad gas valve. Our Gas Fireplace Repair technicians clean the intake, clear the cap, and test the thermopile and valve before replacing anything. Most pilot problems on St. Helena hillside properties turn out to be airflow obstruction, not failed electronics, and we’d rather show you that than sell you a part you don’t need.
Flue Cleaning and Relining for Wood-to-Gas Conversions
Many St. Helena Victorians still have their original clay-tile flues, and venting a modern gas insert into a chimney built for open wood fires creates acidic flue-gas condensation. That condensate eats the original mortar and clay tile from the inside. When we convert one of these downtown brick homes to gas, we reline the flue first, typically with a HeatShield-resurfaced system or a new DuraFlex liner, and we cap it properly with a Famco or Olympia Chimney cap matched to the existing stack.
Outdoor Fireplace and Wood-Fired Oven Service
St. Helena’s luxury estates often include outdoor hearths, wood-fired pizza ovens, and guest-house fireplaces that see intense use during harvest season. We service all of it. If you’re prepping for tasting weekends or harvest dinners, book the sweep and the gas check at the same time. One visit, everything ready before your first guests arrive.

Common Gas Fireplace Repair Problems We See in St. Helena Homes
- Acidic condensate in original clay-tile flues. Downtown St. Helena’s 1880s – 1890s brick chimneys were built for wood smoke, not gas exhaust. Modern gas inserts vented into these flues produce condensation that erodes original mortar and clay tile, often discovered only when the flue gets its first camera inspection.
- Ash and ember debris from the Glass Fire corridor. Hillside estates adjacent to the 2020 burn zones, Spring Mountain, Howell Mountain, and the surrounding chaparral, collect wind-blown ash in chimney caps and air intakes. Homeowners mistake the resulting weak flame and pilot outages for a failed gas valve.
- Rain intrusion through deteriorating crowns and flashing. Valley-floor storms hit these older stacks hard. Water works down through failed crowns and reaches the smoke chamber, warping dampers and shorting the electronic ignition modules on high-end gas inserts.
- Seized dampers on wood-to-gas conversions. When a wine-country Victorian gets a gas insert, the original damper often gets left in place. Over time it seizes from condensate and soot, blocking proper draft and causing the unit to short-cycle. We address the damper as part of every conversion.

FAQs – Gas Fireplace Repair in St. Helena
It’s usually the chimney. Original 1880s – 1890s brick chimneys on and around Main Street were built for open wood fires, not modern gas exhaust, and the acidic condensate from gas combustion corrodes the old mortar and clay tile, which then obstructs draft and blows out the pilot. We diagnose this with a Level 2 camera inspection so you can see the condition of the flue yourself before any repair is recommended. Call (336) 863-3889 and we’ll schedule the camera run.
Yes, and it matters more here than most places. St. Helena’s surrounding chaparral and oak woodland hillsides create persistent wildfire exposure, and chimney openings regularly collect wind-blown ash and embers from regional fire events, especially in the Glass Fire corridor. That debris clogs air intakes, causes sooting, and hides early signs of flue damage. An annual service keeps the unit burning clean and catches small problems before harvest season, when you need it most. Book your pre-season appointment at (336) 863-3889.
Yes, that’s one of our most common jobs in St. Helena. We reline original clay-tile flues using HeatShield resurfacing or a new DuraFlex liner sized specifically for gas exhaust, then cap the stack with a proper Olympia Chimney or Famco cap. The work typically runs $2,800 – $6,500 in St. Helena, and we’ll give you a written price after the camera inspection shows us exactly what’s inside your flue. Call (336) 863-3889 and we’ll start with the inspection.
That smoky smell is almost always wind-blown ash and ember debris lodged in the chimney cap, the air intake, or the flue itself, especially on hillside parcels near the 2020 Glass Fire burn zones above Spring Mountain and Howell Mountain. The debris blocks proper draft and pushes combustion byproducts back into the room. We clear the cap and intake, verify the flue is unobstructed, and test the full ignition sequence. If you’re smelling smoke now, call (336) 863-3889 and stop running the unit until we’ve looked at it.
No, gas log sets don’t produce creosote, which is the tar-like wood-smoke byproduct that causes chimney fires. But a gas log set venting into an old unlined or clay-tile flue will produce acidic condensation that corrodes the original mortar and tile, and that damage can become a fire hazard over time. That’s why every wood-to-gas conversion in St. Helena should start with a camera inspection of the existing flue, and why we document everything you need to see before recommending a reline. Call (336) 863-3889 to schedule yours.
