What’s actually involved
Wood-to-Gas Fireplace Conversion is the project of replacing an existing wood-burning fireplace with a clean, on-demand gas appliance. There are four conversion paths, and the right one depends on your existing chimney condition, your gas-line situation, and the look you want when finished. The vented gas log set ($800-$1,800 installed) is the budget entry — a set of ceramic logs sitting on a steel burner that drops into your existing firebox. The fire is real flame, the original chimney still vents (damper open), and the conversion is the most reversible of the four. The sealed-combustion gas insert ($2,500-$5,500) slides into the existing masonry opening and seals the front with a glass panel — much higher heating efficiency (60-75%+) than a vented log set (10-25%), but requires a stainless-steel liner upgrade in the existing flue per IRC G2425. The direct-vent gas fireplace ($3,800-$8,500) is a brand-new sealed appliance that vents through an exterior wall (no chimney required) — the cleanest option when the existing chimney is in poor shape. The full rebuild ($6,500-$14,000) tears out the old chase, installs a new gas fireplace, and finishes the wall to your design — typically chosen when the homeowner wants a different look or location for the fireplace.
The chimney side determines what’s possible. If you have a sound masonry chimney with intact flue tiles, you can do any of the four paths. A vented log set is the simplest install (drop in, connect gas, light pilot). A sealed gas insert requires a continuous stainless-steel liner sized to the appliance’s flue collar diameter (typically 4″-6″) — code-mandated per IRC G2425. If your chimney has cracked or shifted flue tiles, missing mortar joints, or a deteriorated crown, those defects need repair before any conversion proceeds (we’ll fold those line items into the conversion quote at substantial labor savings, since we’re already on-site with scaffold and access). If the chimney is too far gone to economically repair, the direct-vent path lets us install a new gas fireplace anywhere in the room with a sealed coaxial vent through an exterior wall — no chimney involvement at all.
The gas-line side is where most conversion projects need real attention. If your home already has a gas appliance line within ~25 feet of the fireplace (a gas water heater, gas stove, or gas furnace), adding a fireplace branch is typically a half-day job and adds $400-$900 to the quote. If the fireplace is on an exterior wall with no nearby gas service, we coordinate with a licensed plumber to run a new branch from the meter, which adds $900-$2,200 depending on routing. Atmos Energy serves most of DFW (Texas Gas Service serves a few sub-areas); the gas company handles meter sizing if you’re adding load that pushes you over existing meter capacity. We pull the city-issued mechanical permit on every conversion — every DFW jurisdiction requires permit + final inspection. Working un-permitted is a non-starter: insurance won’t cover an un-permitted gas-appliance fire, and resale disclosure becomes a problem.
ROI on a wood-to-gas conversion is straightforward to calculate. Most DFW homes burn 2-4 cords of wood per season ($700-$2,800/yr at current firewood prices) plus the required annual sweep ($249-$399 for a Level 2 inspection">Level 2 inspection on a wood-burning system). After conversion, fuel cost drops to $80-$220/yr (typical DFW use pattern) and the annual maintenance cost drops to $149-$225 (gas appliance check + tune-up). That’s $520-$2,750 in annual savings, plus the elimination of creosote, ash, chimney-fire risk, and the wood-storage hassle. Payback is typically 1.5-3 years on a vented gas log set, 3-6 years on a quality insert. The conversion also opens up summer usability — gas fires run on demand without the 30-minute ramp-up of wood, which matches DFW’s actual fireplace use pattern (short ambience-driven sessions, not all-day burns).
Why this matters in DFW specifically
DFW is uniquely well-suited for wood-to-gas conversions. The cold-weather window is short (typically Nov-Feb), so wood-burning fireplaces sit unused 8+ months a year while still costing $249-$399 in mandatory annual sweeps. DFW’s wet-fall weather accelerates creosote buildup (stage-2 and stage-3 glazed creosote forms faster in humid conditions), which drives the Level 2 inspection cost up. Gas service infrastructure is excellent across the Metroplex — Atmos Energy and Texas Gas Service together cover virtually every residential address. Building-code adoption is uniform: all DFW jurisdictions enforce IRC G2425 (fuel gas) and IFGC. The result: fast permit processing (3-5 business days typical), reliable gas-utility response, and a homeowner ROI that beats most home-improvement projects.
Our process
- Schedule the assessment — Call or email — we confirm an appointment window typically within 24-48 hours. Inspection is free; we evaluate firebox condition, flue/liner condition, gas-line proximity, venting options, and your design preferences.
- On-site evaluation — Trained tech inspects the existing chimney/firebox, measures opening dimensions, locates the nearest gas service, and walks all four conversion paths with you (gas log set, insert, direct-vent, full rebuild). Photos of finished DFW conversions for reference.
- Written quote with appliance options — Fixed-price scope in writing within 2-3 business days, with 2-3 appliance options at different price points. Conversion is quoted as one all-in number — gas line work, permit, appliance, install, finish work, and final inspection are all bundled.
- Permit + gas-line preparation — We pull the mechanical permit (and the gas-line permit if a new branch is required) before scheduling the install. Gas-line work is coordinated with our licensed plumbing partner — typically a 4-8 hour job, done 1-2 days ahead of the appliance install.
- Conversion install (1-2 days) — Wood-to-Gas Fireplace Conversion performed to NFPA 211, IRC G2425 (fuel gas), and CSIA standards. Containment plastic protects the rest of your home; old wood-burning components removed cleanly; new appliance connected, leak-tested, and fired.
- Final inspection + handover — City mechanical inspector signs off the install (we coordinate the appointment). Manufacturer warranty paperwork (5-10 yrs on appliance, lifetime on workmanship), operating instructions, maintenance schedule, before/after photos delivered same-day.

Frequently asked questions
How long does a wood-to-gas fireplace conversion take?
Total elapsed time from signed quote to working gas fireplace is typically 2-4 weeks across DFW. The on-site work is short — gas-line installation is a half-day, the appliance install + connection is 1-2 days, and final inspection is a 30-minute appointment. The lead time is mostly permit processing (3-5 business days) and appliance order/delivery (1-2 weeks for in-stock units, 3-6 weeks for special-order finishes).
Do I need a permit for a wood-to-gas conversion?
Yes — every DFW jurisdiction requires a mechanical permit for fuel-gas appliance installation, plus a final inspection by the city. We pull both the mechanical permit and the gas-line permit (when required) as part of the project. Permit fees pass through at cost ($85-$225 typical). Trying to skip the permit is a non-starter — homeowners insurance won’t cover an un-permitted gas appliance fire, and resale disclosure becomes a problem.
Which conversion path should I choose?
Vented gas log set ($800-$1,800) is the right choice for budget-focused homeowners with a sound existing chimney who want occasional ambience. Sealed gas insert ($2,500-$5,500) is right for homeowners who actually want heat output (60-75% efficiency vs 10-25% for vented logs) and have a sound chimney that supports a stainless liner. Direct-vent ($3,800-$8,500) is right when the chimney is in poor shape or you want a fireplace where there isn’t one currently. Full rebuild ($6,500-$14,000) is right when you want a different look or location entirely.
How much does the gas line itself cost?
Depends on what’s already there. Existing gas appliance within 25 feet → $400-$900 to branch a new line. Brand-new line from the meter → $900-$2,200 depending on routing complexity (crawl space, attic, or trench around foundation). The gas line cost is always included in the bundled written quote — no surprise add-ons after work begins.
What code applies to wood-to-gas conversions in DFW?
DFW jurisdictions adopt IRC (International Residential Code) and IFGC (International Fuel Gas Code) — the relevant section is IRC G2425 (chimneys and vents serving gas appliances). Combustion air, vent sizing, clearance to combustibles, gas-line sizing, and shutoff valve placement are all code-specified. We also follow NFPA 211 for the chimney/vent side and the manufacturer’s installation instructions (which are themselves code-required reading).
Can I convert back to wood-burning later if I change my mind?
A vented gas log set is the most reversible — pull the logs and gas connection and the original masonry firebox is intact for wood use again (after a fresh Level 2 inspection). A gas insert is partially reversible — the insert lifts out, but the stainless liner stays (no harm; actually an upgrade for any future wood use). Direct-vent and full rebuild are not practically reversible. Most converted homeowners do not regret it; the maintenance, mess, and fire-risk reduction is significant.
Do you offer financing for wood-to-gas conversions?
Yes — we partner with Sunbit and other home-improvement lenders that approve in 30 seconds with a soft credit pull (no impact on credit score). Typical projects qualify for 12-60 month terms with 0% promo APR available on shorter terms. Most DFW homeowners pay cash for gas log set conversions and finance inserts/direct-vent/full-rebuild projects.
