Fireplace Installation Cost Calculator

Fireplace installation typically runs from about $1,500 to $10,000+, and the type is what drives the huge range. Electric fireplaces are cheapest (often $1,500 or less installed, since they plug in and need no venting), and ethanol units are similarly affordable. Gas is mid-range — a gas insert or a built-in direct-vent gas fireplace commonly runs $3,500 to $7,000+ with the unit, gas line, and venting. Wood stoves land in a similar range with their flue. A traditional masonry wood-burning fireplace with a full chimney is by far the priciest, often $10,000 to $20,000+. The installation location, surround finish, and extras like a gas line and venting fill in the rest. Enter your type, location, and finish in the calculator above for a localized number.

It comes down to budget, the heat and ambiance you want, and whether you have venting and gas. Electric is the easiest and cheapest — plugs into an outlet, needs no venting, goes almost anywhere, and gives flame-effect ambiance plus modest supplemental heat, though the flames are simulated. Gas is the popular all-rounder: real flames, strong instant controllable heat, and low maintenance, but it needs a gas line and usually venting, so it costs more. Wood-burning (a masonry fireplace or a wood stove) gives authentic fire, aroma, and serious heat, but needs a chimney or flue, wood handling, and upkeep — and masonry is the most expensive. Ethanol burns clean with no venting for real (small) flames anywhere. The calculator compares electric, ethanol, gas insert, built-in gas, wood stove, and masonry.

Both burn gas, but they install differently. A gas insert is a sealed firebox that slides into an existing fireplace opening — usually an old, inefficient wood-burning masonry fireplace — and vents up the existing chimney with a liner. Because it reuses the existing structure and chimney, it's the more cost-effective way to convert a drafty wood fireplace into an efficient gas one; the main work is the gas line, the liner, and finishing. A built-in gas fireplace is a complete appliance framed into a wall where there may be no prior fireplace, with its own venting run out an exterior wall or up through the roof, then finished with a surround and mantel. It gives you a brand-new fireplace anywhere with design flexibility, but needs framing, venting, and finishing, so it costs more. Choose an insert to upgrade an existing fireplace, a built-in to add one where none exists.

It depends entirely on the type, and these requirements drive much of the cost and feasibility. Electric fireplaces need none — just an outlet (high-output models may want a dedicated circuit), which is why they install anywhere. Ethanol (ventless) units also need no venting, chimney, or gas — just good room ventilation. Gas fireplaces need a gas line, and most need venting: direct-vent models vent through an exterior wall or roof (no full chimney), while ventless gas has code restrictions in some areas; a gas insert vents up the existing chimney with a liner. Wood-burning fireplaces and stoves require a chimney or flue — a masonry fireplace needs a full masonry chimney (expensive), a stove needs chimney pipe. Reusing an existing chimney is cheapest; running new venting or building a chimney is costly. Always have a pro assess venting, gas, and clearances — proper venting is a carbon-monoxide and fire-safety issue.

Both are far more efficient than a traditional open wood fireplace, which loses most of its heat up the chimney and can even pull heated air out of the house. Gas fireplaces — especially direct-vent and insert models — are efficient heaters, converting most of the fuel to usable heat (many rate 70–90%+), delivering strong instant heat, and a gas insert dramatically improves an old wood fireplace's efficiency. Where natural gas is available, gas is often an economical heat source. Electric fireplaces put essentially all their electricity into room heat with no venting losses, but the output is modest (space-heater level, up to about 5,000 BTU / 1,500 W), best for zone-heating one room rather than the whole house; the operating cost tracks your electricity rate. For supplemental zone heat and ambiance, electric is efficient and flexible; for stronger real-flame heat, gas excels. Check the unit's efficiency rating and BTU output.

Many can, but feasibility depends on the type's venting and fuel needs, the wall and structure, clearances, and code. Electric is the most flexible — needing only an outlet and no venting, it fits living rooms, bedrooms, basements, offices, and works as a wall-mount or media console, ideal where venting or gas isn't available. Ethanol is similarly flexible with good ventilation. Gas is fairly flexible but needs a gas line and venting, so it's easiest on or near exterior walls where gas can be run. Wood-burning fireplaces and stoves are the least flexible — they need a chimney or flue routed up through the structure and roof, clearances to combustibles, a hearth, and structural support (especially heavy masonry), so placement is more constrained. For a room without existing venting or gas, electric (or ethanol) is usually the practical choice. Always follow manufacturer clearances and code.

It can add both appeal and value, and fireplaces are a feature many buyers want — they bring ambiance, warmth, and a focal point, and homes with them can be more attractive and sometimes sell at a premium, especially in colder climates. A well-executed fireplace in a main living area — a clean, low-maintenance gas unit with a nice surround, or a tasteful built-in — tends to add the most. The return varies by market and how well it fits the home; a cheap-looking or ill-suited installation adds less. As with most upgrades, you may not fully recoup the cost purely at resale, so treat it partly as a lifestyle investment: the day-to-day ambiance and supplemental heat provide real value while you live there. Choosing a quality unit, a tasteful finish, good placement, and proper permitting maximizes both appeal and value.

Usually, yes — especially for gas and wood units. Running a new gas line, installing venting or a chimney, and any structural framing are permitted work in most jurisdictions, and gas, venting, and the installation typically require inspection to confirm it's safe and code-compliant (proper clearances, correct venting, no carbon-monoxide risk). Even a built-in electric with framing may need a building permit. A plug-in electric or ethanol unit that just sits on the floor usually doesn't. Permitting protects you — it ensures a life-safety installation and keeps things clean for insurance and resale. A reputable installer typically pulls the permit and arranges inspection as part of the job. The calculator includes a permit-and-inspection add-on so you can price it in.

The finish around the firebox is a real cost lever and turns the fireplace into a room focal point. A basic finish — a standard mantel and trim — is the baseline. A mid-range surround with tile or stone veneer adds about 15% for the material and the mason or tile-setter's labor. A premium finish — a full floor-to-ceiling stone surround with a custom mantel — adds about 35% and is often the single biggest design expense after the unit itself. Stone and tile work also add time and may need to cure. If you want the fireplace to be a statement wall, budget for the premium finish; if it's about heat and basic ambiance, a simple mantel keeps the cost down. The calculator lets you pick basic, mid-range, or premium, plus a custom-mantel add-on.

It ranges from a few hours to a week-plus, by type. A plug-in or wall-mount electric goes in within a few hours, and a built-in electric with some framing is about a day. Ethanol is similarly quick. Gas takes longer for the gas line and venting: a gas insert into an existing fireplace is often a day or two, while a built-in direct-vent gas fireplace that needs wall framing, new venting through the wall or roof, a gas line, and a finished surround typically takes a few days. Wood stoves with a flue take a couple of days. A traditional masonry fireplace with a full chimney is the longest — a week or more for the masonry and chimney, plus curing. Stone or tile surrounds, electrical, permitting lead time, and inspections can extend the schedule. Your installer can give a firm timeline after assessing the type, venting, and finish.
