Gas Fireplace Conversion Cost in DFW: Process, Pricing, and What to Expect
Converting a wood-burning fireplace to gas is one of the most rewarding remodels we do. Done well, it preserves the architectural character of your existing fireplace, eliminates the maintenance and air-quality concerns of wood-burning, and gives you the ease of a push-button or smart-home-controlled flame anytime you want it. Done beautifully, the conversion becomes the moment your living room finally feels finished. This guide walks you through the full process, real DFW pricing for 2026, and the design decisions that turn a functional conversion into a beloved feature.

The Conversion at a Glance
| Conversion Type | Typical DFW Cost (2026) | Timeline | Best For |
|---|---|---|---|
| Gas log set (vented) in existing firebox | $1,800 – $4,200 | 1–3 days | Quick aesthetic conversion, low budget |
| Direct-vent gas insert in existing firebox | $5,500 – $9,500 | 1–2 weeks | Most common — maintenance-free real flame |
| Direct-vent insert + new stainless liner | $7,200 – $12,800 | 2–3 weeks | Older chimneys, code compliance |
| Full conversion with new surround | $12,000 – $24,000 | 3–5 weeks | Aesthetic remodel + fuel conversion combined |
| Wood-burning to ventless gas | $3,500 – $6,800 | 1 week | Smaller rooms, limited venting access |
The Three Most Common Conversion Paths
Path 1: Gas Log Set (The Quickest Conversion)
A vented gas log set is the simplest conversion: artificial ceramic logs over a gas burner, installed in your existing firebox, with the existing chimney as the vent. The damper stays open during use. This is the lightest-touch path — it preserves the original firebox aesthetic almost completely, costs the least, and installs in 1–3 days.
The trade-offs: the flame is real but typically less luminous than a direct-vent insert, the heat output is lower (most of the warm air goes up the chimney with the combustion gases), and the chimney still needs to be inspected and maintained (less often than wood, but not zero).
This path is right when budget is the dominant constraint, the original firebox is beautiful and you don’t want to change it, or you want the look of a fire without significant remodeling.
Path 2: Direct-Vent Gas Insert (The Most Popular Conversion)
A direct-vent gas insert is a complete sealed fireplace unit that slides into your existing masonry firebox. A new stainless flexible liner runs up the existing chimney as the exhaust vent (and a coaxial supply vent), and the front of the insert presents a clean modern firebox with hand-painted ceramic logs, glass front, and either traditional or contemporary aesthetics. This is the conversion we recommend most often in DFW, and it transforms the fireplace’s daily usability.
What you get: real sealed flame, dramatically higher heat output than gas logs (most direct-vent inserts deliver 60–75% efficiency vs ~20% for vented logs), zero combustion byproducts entering the room, push-button or smart-home control, and almost no maintenance. The chimney is no longer being used as a wood-burning flue — it’s a chase for the venting — so traditional chimney sweep work is no longer needed (annual service of the insert replaces it).
The trade-off: investment level is meaningfully higher than gas logs, the installation takes 1–3 weeks, and the visible firebox changes (the original brick or firebrick is hidden by the new insert face). For most homeowners this is a strong gain — the new face is more attractive than a worn 1980s firebox.
Path 3: Full Aesthetic Remodel with Conversion
Many homeowners use the conversion moment to also remodel the surround. The fireplace is already an active project; the trades are already on site; the design team is already engaged. Adding a new stone surround, mantel, and hearth at this point costs dramatically less than doing the work separately later.
This is where conversions become transformative. A 1990s brick fireplace becomes a modern honed-limestone surround with a sleek linear gas firebox. A dated 1980s wood-burning insert becomes a clean contemporary direct-vent fireplace with a stacked porcelain slab surround running floor to ceiling. The conversion is the gateway to a fully renovated focal point.
What Happens During a Conversion (Week by Week)
Days 1–2: Assessment and design. We visit the home, evaluate the existing firebox and chimney condition (often a Level 2 inspection">Level 2 inspection is part of the visit), confirm gas line accessibility, and walk you through firebox and surround options. Final selections are made and the unit is ordered.
Days 3–10: Permitting and unit arrival. Gas line permit pulled with the city, the insert and any surround materials arrive at our warehouse, the installation date is firmed up.
Installation week: Day 1. Protection laid (drop cloths, plastic containment), existing wood-burning components removed, chimney pre-vacuumed if needed, gas line stubbed to the firebox if not already in place.
Installation week: Day 2. Stainless liner installed top-down through the existing chimney, insulation wrap completed, top termination installed with new stainless cap.
Installation week: Day 3. Insert set in firebox, connected to liner, gas connection completed and pressure-tested, electrical/control work for ignition and any smart-home integration.
Installation week: Day 4. Firebox face and any surround changes installed, final commissioning of the unit, walk-through with homeowner on operation, controls, and ongoing care.
Inspection and close-out. City inspector closes the permit, final documentation and warranty registration delivered, first service appointment scheduled.
What Drives the Cost
Insert tier. A builder-grade direct-vent insert is $1,800–$2,800. A premium linear or traditional insert with hand-painted logs, IPI ignition, and smart-home integration is $4,500–$8,500. The unit choice drives the most variation in price.
Chimney condition. A chimney with a sound existing flue often does not need extensive remediation. A chimney with cracked tile, missing crown, or other issues may need partial repair before the new liner can be installed.
Gas line work. Existing gas line within reach: minimal cost. Running new gas line through finished space: $400–$1,200.
Surround scope. Keeping the existing surround: included in baseline. Tearing out and replacing with new stone or porcelain: $5,000–$18,000 added depending on material.
Permits and inspection: $300–$700 typically.
Decision Tree: Which Conversion Is Right for You?
- Budget is the dominant constraint and the existing firebox is beautiful? Vented gas log set.
- Want the lowest-maintenance, highest-quality real flame experience? Direct-vent gas insert with new stainless liner.
- Doing the conversion and dislike the existing surround? Full conversion with new surround. The economics favor doing both at once.
- Living in a smaller room with limited venting access? Consider ventless gas — see our vented vs ventless guide first.
- The chimney itself has known issues (cracked tile, missing cap, water intrusion)? Direct-vent insert with new stainless liner is the right path — it solves the chimney issues and the conversion in one project.
Living With the Converted Fireplace
The transformation in daily use is dramatic. The fire comes on with a remote, a wall switch, or a smartphone app. No kindling, no logs, no ash, no smoke. The flame is real and warm. Most homeowners use the fireplace dramatically more often after conversion — once weekly becomes nightly during the winter, because the friction is gone.
Annual service runs $150–$300 and includes inspection of the burner, logs, glass, gaskets, and ignition system. No chimney sweep needed for the gas insert configuration. Plan for the unit to perform beautifully for 20–25 years before major component service is needed.
Frequently Asked Questions
Can any wood-burning fireplace be converted to gas?
Nearly always, yes. We’ve converted brick fireboxes from the 1920s, prefab metal fireboxes from the 1970s, and full masonry fireplaces from every era. The few exceptions: fireboxes with severe structural damage (cracked firebrick that compromises the insert installation) or chimneys with unresolved structural issues. We confirm suitability during the initial assessment.
Do I need a gas line already at the fireplace?
Helpful but not required. If gas service is available to the home, we can run a line to the fireplace. Existing gas service within 20 feet keeps costs low ($200–$500). Longer runs through finished spaces add cost but rarely make the project unfeasible.
Will the converted fireplace look as good as a wood-burning one?
Modern direct-vent gas inserts with hand-painted ceramic logs deliver a flame and ember bed that — at conversational distance — most people read as a real wood fire. The premium tier (Mendota, Heat & Glo, FireplaceX, Valor) is genuinely indistinguishable from wood at first glance. The ambiance experience is excellent.
How much does the conversion increase home value?
DFW realtor data suggests gas conversion adds $4,000–$12,000 in perceived value to most homes when paired with a refreshed surround, and removes a ‘deferred maintenance’ flag that wood-burning fireplaces sometimes carry with buyers. In luxury homes with thoughtful design, the conversion is often a strong resale positive.
Can I still have a wood fire after converting?
No. The conversion is permanent — the firebox is now configured for gas only, the chimney has been re-lined as a gas vent (which is not rated for wood-burning), and the insert physically occupies the firebox space. Conversion is a one-way decision.
Is the gas line and meter on my home big enough for the conversion?
Almost always, yes — residential gas service in DFW is sized to support multiple appliances including a fireplace. The exception is older homes (pre-1970s) with original gas service that may benefit from a meter upgrade. We check this during assessment and coordinate with the utility if upgrade is needed.
What is the most-overlooked detail in a conversion?
The chimney cap and crown after conversion. The new stainless liner terminates above the existing chimney with a proper rain cap, and the crown — the masonry cap on top of the chimney — is often deteriorated from years of wood-burning exposure. Replacing or sealing the crown during conversion adds $300–$700 and prevents water damage to the new liner installation. We always evaluate it as part of the scope.
