Fireplace and Wood Stove Installation Cost in Southern Maryland: 2026 Price Guide

By Gray & Sons Contracting · September 14, 2026

A fireplace or wood stove installation in Southern Maryland costs $2,500 to $15,000 in 2026, depending on the fuel type and whether the home has an existing chimney. A wood stove installed into an existing masonry chimney costs $4,000 to $8,000. A new freestanding wood stove with no existing chimney costs $5,500 to $9,000 or more. A gas fireplace insert in an existing masonry firebox costs $3,500 to $8,000, while a new direct-vent gas fireplace built from scratch costs $5,000 to $15,000 or more. Pellet stoves fall in the $3,000 to $6,000 range installed, and electric fireplaces run $200 to $5,000 depending on whether you want a plug-in unit or a built-in installation with a custom surround.

Southern Maryland winters are mild compared to Pennsylvania or New England, but they are not warm. Calvert, St. Mary's, and Charles County see average January lows in the mid-20s, with stretches of single-digit cold snaps in most winters and 15 to 25 freeze-thaw cycles between November and March. A fireplace or wood stove is not the primary heating system for most homes in the tri-county area, but it is a highly effective supplemental heat source that reduces HVAC costs, adds ambiance, and, critically for this region, provides backup heat during power outages.

That last point is the one that matters most in Southern Maryland. The same storms that drop trees on power lines leave homes without heat when the electric furnace, heat pump, or gas furnace blower stops running. A wood stove or pellet stove with a gravity-fed or battery-backed system heats the main living area without any electricity at all. Many homeowners in Lusby, Solomons, Hollywood, Leonardtown, Mechanicsville, Nanjemoy, and the rural stretches of all three counties keep a wood stove for exactly this reason, it is the heating system that works when nothing else does.

September and October are the ideal time to install. Contractors are past the summer rush but before the heating-season scramble, lead times on stove units and chimney components are shorter, and the installation is done and inspected before the first cold night. Here is what every option costs, what the installation involves, and which type makes the most sense for your home.

Cost by Fireplace and Stove Type

Labor accounts for 45 to 55 percent of the total project cost on most fireplace and stove installations. In Southern Maryland, basic installation labor runs $400 to $800 for a straightforward replacement or insert job. Complex installations, running new chimney pipe through two stories, building a new hearth, framing a surround, running a gas line, push labor to $1,000 to $4,000 or more.

Wood Stove Installation Cost

Wood stoves are the most popular supplemental heating option in rural Southern Maryland, and for good reason. They produce serious heat, a modern EPA-certified wood stove rated at 50,000 to 80,000 BTU heats 1,500 to 2,500 square feet, and firewood is abundant and relatively cheap in this area. A cord of seasoned hardwood from a local supplier in Calvert, St. Mary's, or Charles County costs $275 to $500, and many homeowners with wooded lots cut and split their own for free.

Replacing an Existing Wood Stove: $3,000 to $5,000

This is the simplest and least expensive scenario. The chimney is already in place, the hearth pad exists, and the stovepipe connects to an existing flue. The old stove is removed, the chimney liner is inspected (and replaced if deteriorated), and the new stove is connected and tested.

If the chimney liner is in good condition, no cracks, no excessive creosote buildup, correct diameter for the new stove, the liner does not need replacing and the project stays at the lower end. If the liner is damaged or the wrong size, add $1,500 to $5,000 for a new stainless steel liner (see chimney costs below).

Installing Into an Existing Masonry Chimney: $4,000 to $8,000

Many older homes in Southern Maryland, particularly the colonials, Cape Cods, and ranches built from the 1950s through the 1980s in places like Prince Frederick, Dunkirk, La Plata, and Waldorf, have masonry fireplaces with clay-tile-lined chimneys that were designed for open wood fires. Converting that masonry fireplace to accept a wood stove or installing a freestanding stove connected to the existing chimney flue requires a new stainless steel chimney liner, a hearth pad that meets clearance requirements, and proper stovepipe connections.

The wide range reflects the condition of the existing chimney. A chimney in good structural condition that just needs a liner and a connection is a $4,000 to $6,000 project. A chimney with cracked mortar, a damaged crown, or a deteriorated flue that needs structural repair before the liner can be installed pushes the project toward $8,000 or beyond.

New Installation With No Existing Chimney: $5,500 to $9,000+

Installing a wood stove in a home that has no chimney at all, common in newer construction and in ranch-style homes built without fireplaces, requires running new Class-A chimney pipe from the stove through the ceiling, attic, and roof. This is the most expensive wood stove installation because of the chimney pipe, the roof penetration, the fire-rated ceiling and wall work, and the framing modifications.

The realistic midpoint for a typical single-story or story-and-a-half home in Southern Maryland is $5,500 to $9,000 for a complete new wood stove installation with Class-A chimney pipe through the roof.

Wood Stove Insert: $3,000 to $6,500

A wood stove insert is a firebox designed to slide into an existing masonry fireplace opening. It converts an inefficient open fireplace, which sends 80 to 90 percent of its heat up the chimney, into a sealed combustion unit that captures 70 to 80 percent of the heat and radiates it into the room. Inserts are the most common fireplace upgrade in Southern Maryland because so many homes already have masonry fireplaces that look nice but heat poorly.

Most insert installations in the tri-county area fall in the $3,000 to $6,500 range. The chimney liner is the variable, a straight, unobstructed chimney in good condition takes a liner quickly, while an offset chimney or one with obstructions requires more labor and possibly a more expensive flexible liner.

Gas Fireplace Installation Cost

Gas fireplaces provide heat at the flip of a switch, no wood splitting, no ash cleanup, no waiting for a fire to build. They are the most convenient option and are popular in newer homes and in finished living spaces where the cleanliness of gas is a priority.

Gas Fireplace Insert: $3,500 to $8,000

A gas insert slides into an existing masonry fireplace opening, similar to a wood insert, but connects to a gas line instead of burning wood. It uses the existing chimney (with a new aluminum or stainless liner for venting) or a direct-vent pipe run up through the existing flue.

The gas line is the variable cost. If the home already has natural gas or propane service and there is an existing gas line near the fireplace (many homes have a gas stub behind the fireplace from original construction), the connection is straightforward, $400 to $600. If a new gas line must be run from the meter or propane tank to the fireplace location, especially through finished walls and floors, the gas line alone can cost $800 to $1,500.

Natural gas is available from Washington Gas in parts of Waldorf, La Plata, White Plains, Indian Head, and limited areas of Calvert County. Most of St. Mary's County and rural Calvert and Charles County rely on propane, which works just as well, the insert simply uses a propane-rated orifice and regulator.

Gas Direct-Vent Fireplace (New Construction): $5,000 to $15,000+

A direct-vent gas fireplace is a sealed unit that draws combustion air from outside and exhausts through a coaxial vent pipe that runs through an exterior wall or up through the roof. It does not need a chimney at all, just a vent pipe penetration. This makes it the go-to option for additions, finished basements, master bedrooms, and any room where there is no existing chimney.

The surround and finish work is where costs diverge dramatically. A basic drywall surround with a simple mantel might add $1,000 to $2,000. A floor-to-ceiling stacked stone surround with a custom hardwood mantel and built-in cabinetry on either side can push the finish work alone past $5,000. The fireplace unit and the gas connection are the functional costs; the surround is the aesthetic investment.

Pellet Stove Installation Cost: $3,000 to $6,000

Pellet stoves burn compressed wood pellets, small, uniform cylinders made from sawdust and wood waste, fed automatically from a hopper into a combustion chamber by an electric auger. They offer a middle ground between the hands-on experience of a wood stove and the convenience of gas: you fill the hopper with pellets (a 40-pound bag lasts 24 to 48 hours depending on the heat setting), set the thermostat, and the stove manages the burn rate automatically.

Most pellet stove installations in Southern Maryland fall in the $3,000 to $6,000 range. The installation is simpler than a wood stove because pellet stoves vent through a small-diameter pipe that exits through an exterior wall, no chimney, no roof penetration. The stove does require electricity to run the auger, the combustion fan, and the control board, which means it does not provide heat during a power outage unless paired with a battery backup or a generator.

Wood pellets are widely available in Southern Maryland. Hardware stores, farm supply stores, and home improvement centers in Waldorf, Prince Frederick, Leonardtown, and California carry them seasonally, typically at $5 to $8 per 40-pound bag or $250 to $350 per ton. A typical household burns 2 to 4 tons per heating season, putting annual fuel cost at $500 to $1,400.

Electric Fireplace Installation Cost: $200 to $5,000

Electric fireplaces are the simplest to install and the least expensive, but they are fundamentally different from wood, gas, and pellet units. An electric fireplace is a space heater with a visual flame effect, it produces 4,000 to 9,000 BTU from a standard 120-volt outlet, which is enough to take the chill off a single room but not enough to heat a significant area of the house. There is no real combustion, no venting, no chimney, and no gas line.

Electric fireplaces make sense in condos, apartments, bedrooms, and home offices where the visual effect is the primary goal and supplemental heat is a bonus. They do not make sense as a serious heating strategy, and they provide no backup heat during a power outage, which eliminates the main reason most Southern Maryland homeowners install a fireplace or stove in the first place.

Chimney and Venting Costs

The chimney or vent system is often the single most expensive component of a fireplace or stove installation, especially when the home does not have an existing chimney in serviceable condition.

A homeowner installing a wood stove with 20 feet of Class-A chimney pipe should budget $940 to $1,600 for the pipe alone, plus $300 to $800 for the roof penetration and flashing, plus $150 to $700 for the cap. A homeowner relining an existing masonry chimney for a wood stove insert should budget $1,500 to $5,000 for the liner, depending on the chimney height and whether insulation wrap is required.

Installation Scenarios: What Your Project Actually Looks Like

Every home is different, but most fireplace and stove projects in Southern Maryland fall into one of these common scenarios.

Scenario 1: Convert an Old Open Fireplace to a Wood or Gas Insert

This is the most common fireplace project in the tri-county area. The home has a masonry fireplace, usually a brick surround in the living room or family room, that looks pleasant but heats inefficiently. An open masonry fireplace sends 80 to 90 percent of the fire's heat up the chimney and can actually cool the house by drawing heated indoor air up the flue.

The fix is an insert. A wood insert or gas insert slides into the existing opening, a new chimney liner goes down the flue, and the surround plate covers the gap between the insert and the masonry opening. The chimney must be inspected first, a chimney inspection costs $100 to $250 and is money well spent, because a chimney with structural damage or heavy creosote buildup needs repair before a liner can be installed.

Typical cost for this scenario: $3,500 to $7,000 for a wood insert with liner, or $3,500 to $8,000 for a gas insert with liner and gas connection.

Scenario 2: Add a Wood Stove to a Home With No Fireplace

The home has no fireplace and no chimney. The homeowner wants a freestanding wood stove in the main living area for supplemental heat and power-outage backup. This requires a new Class-A chimney pipe run from the stove through the ceiling, attic, and roof (or in some cases, through an exterior wall and up the outside of the house), a hearth pad on the floor, and wall protection behind the stove.

Typical cost for this scenario: $5,500 to $9,000 for a mid-range EPA-certified stove with full chimney installation.

Scenario 3: Add a Gas Fireplace to a Room Addition or Finished Basement

A new room addition, a finished basement, or a master suite remodel includes a fireplace as part of the design. A gas direct-vent fireplace is the standard choice because it requires only a vent pipe through an exterior wall, no chimney, no significant structural work. The fireplace becomes part of the room's finished design with a surround that matches the rest of the space.

Typical cost for this scenario: $5,000 to $12,000 depending on the fireplace unit and the surround finish.

Scenario 4: Replace an Old, Non-EPA-Certified Wood Stove

Many older homes in rural Calvert, St. Mary's, and Charles County have wood stoves that predate the EPA's 1988 emissions standards. These older stoves are less efficient (40 to 50 percent efficiency versus 70 to 80 percent for modern units), produce significantly more smoke and creosote, and may not meet current code for insurance purposes. Replacing the old stove with a new EPA-certified unit is straightforward if the chimney and hearth are in good condition.

Typical cost for this scenario: $3,000 to $5,000 for a new stove and installation with existing chimney infrastructure.

Factors That Affect Your Price

Home Layout and Chimney Run

A single-story home with a short, straight chimney run through the attic and roof is the least expensive to install. A two-story home where the chimney pipe runs through a second-floor room, through a closet or chase, and then through the attic and roof requires more pipe, more labor, and more fire-rated framing work. Every additional foot of chimney pipe adds $47 to $80, and every additional ceiling or wall penetration adds labor cost and complexity.

Existing Infrastructure

A home with an existing masonry chimney in good condition saves $3,000 to $10,000 compared to a home that needs a new chimney. A home with an existing gas line near the fireplace location saves $400 to $1,500 on gas line work. A home with an existing hearth pad that meets code saves $200 to $1,200. The more existing infrastructure you have, the less the installation costs.

Stove or Fireplace Quality

Wood stove prices range from $1,000 for a basic steel box to $4,000 or more for a soapstone or cast-iron unit from a premium manufacturer. The more expensive stoves are not just prettier, they hold heat longer (soapstone radiates for hours after the fire dies), burn more efficiently, produce less creosote, and last 20 to 30 years or more. A $1,000 stove will heat your house, but a $2,500 stove will heat it better, longer, and with less firewood.

Finish Work and Aesthetics

The surround, mantel, and hearth materials can double the cost of a gas fireplace installation. A basic drywall surround costs $500 to $1,000. A natural stone surround, stacked stone, cultured stone, or fieldstone, costs $2,000 to $5,000. A floor-to-ceiling stone surround with a custom mantel and built-in shelving can exceed $8,000 in finish work alone. The fireplace unit is a fixed cost; the aesthetics are where budgets stretch.

Southern Maryland Heating Considerations

Mild but Real Winters

Southern Maryland's climate is classified as humid subtropical, which means warm summers and mild winters. But "mild" is relative. Average January temperatures in the tri-county area range from highs in the mid-40s to lows in the mid-20s, with multiple cold snaps each winter dropping into the teens or single digits. The 15 to 25 freeze-thaw cycles between November and March are enough to justify supplemental heating, particularly in drafty older homes that are expensive to heat with a heat pump or electric furnace alone.

A wood stove sized for 1,500 to 2,000 square feet can heat the main living area of most Southern Maryland homes to comfortable temperatures on the coldest nights, allowing the central HVAC system to cycle less frequently. Homeowners who heat primarily with a heat pump, and heat pumps lose efficiency below 30 to 35 degrees, find that a wood stove or gas fireplace covering the common areas during cold snaps reduces the reliance on expensive electric resistance backup heat.

Power Outage Resilience

This is the strongest argument for a wood stove or gas fireplace in Southern Maryland. The tri-county area experiences multi-day power outages from summer thunderstorms, tropical storms, nor'easters, and ice storms. When the power goes out, electric furnaces and heat pump systems stop completely. Gas furnaces stop too, the blower motor that distributes heat requires electricity.

A wood stove requires no electricity at all. Load it with wood, light it, and it heats the room by direct radiation and convection. In a well-insulated home, a single wood stove in the main living area can keep the house above 60 degrees even in a January cold snap with no utility power.

A direct-vent gas fireplace with a standing pilot light and a millivolt ignition system (no electronic ignition) also operates without electricity, the pilot light generates enough millivolt current to open the gas valve when the switch is turned on. Not all gas fireplaces have this feature, so if power-outage operation is a priority, confirm the unit has millivolt ignition before purchasing.

Pellet stoves require electricity for the auger and blower and do not operate during outages without a battery backup or generator. Electric fireplaces, obviously, do not operate without power.

Firewood Availability

Southern Maryland's abundant hardwood forests make firewood cheap and accessible. A cord of seasoned oak, hickory, or maple from a local supplier costs $275 to $500, and many suppliers in Calvert, St. Mary's, and Charles County deliver. Homeowners with wooded lots often harvest and split their own firewood at no cost beyond labor and chainsaw fuel. This makes the ongoing fuel cost of a wood stove significantly lower than gas or pellet alternatives for households willing to do the work.

For comparison, heating a 1,500-square-foot area with a wood stove for a typical Southern Maryland winter (roughly November through March, with moderate use) requires 2 to 4 cords of firewood, costing $550 to $2,000 from a supplier. The same heating from propane costs $800 to $1,500 per season, and from a pellet stove costs $500 to $1,400 in pellets. Wood is the cheapest option if you buy it locally, and essentially free if you cut your own.

Wood vs. Gas vs. Pellet: Which One to Choose

The right choice depends on what you value. If backup heat during outages and low fuel cost are the priorities, a wood stove is the clear winner. If convenience and clean operation matter most, gas is the answer. If you want automated wood-fuel heat without the chimney and ash of a wood stove, a pellet stove splits the difference, but remember the power dependency.

Permits and Code Requirements

Fireplace and wood stove installations in Calvert, St. Mary's, and Charles County require a building permit. The permit ensures the installation is inspected for compliance with the International Residential Code (IRC), the International Mechanical Code (IMC), and the manufacturer's installation instructions, all three of which dictate clearances to combustibles, chimney height, hearth dimensions, and venting requirements.

Any contractor who suggests skipping the permit is a contractor you should not hire. The permit protects you, it ensures an independent inspector verifies that clearances are correct, the chimney is properly installed, and the installation will not start a fire. It also protects your homeowner's insurance: an unpermitted fireplace or stove installation can void your fire coverage.

What to Expect During Installation

Wood Stove Installation Timeline

A wood stove installation into an existing chimney typically takes one day, 4 to 8 hours of on-site work. A new installation with Class-A chimney pipe through the roof takes one to two days, depending on the chimney run length and the complexity of the ceiling and roof penetrations. The chimney inspection should happen before installation day so any repair work can be scheduled in advance.

Gas Fireplace Installation Timeline

A gas insert into an existing fireplace takes one day. A new direct-vent gas fireplace with framing and surround work takes two to four days, one day for rough framing and gas line work, one day for the fireplace installation and vent pipe, and one to two days for the surround and finish work. If the surround involves stone or tile, the finish work may take longer.

The Inspection

After installation, the county inspector visits to verify code compliance. The inspector checks clearances to combustibles, chimney height, hearth dimensions, liner installation, gas connections (for gas units), and carbon monoxide detector placement. Pass the inspection and the project is complete. If the inspector finds deficiencies, the contractor corrects them and the inspector returns.

Maintenance Costs

A fireplace or stove is not a set-and-forget appliance. Every fuel-burning heating appliance requires regular maintenance for safety and performance.

Annual maintenance budget for a wood stove: $150 to $350 for the chimney sweep, plus firewood. The chimney sweep is not optional, creosote buildup in the flue is the primary cause of chimney fires, and a chimney fire in a home with a wood stove is a preventable disaster. The National Fire Protection Association (NFPA) recommends annual chimney inspection and cleaning for all wood-burning appliances.

Annual maintenance budget for a gas fireplace: $100 to $250 for the annual service, plus gas fuel cost. Gas fireplaces produce no creosote but still require inspection to verify the gas valve, thermocouple, pilot assembly, and vent system are functioning correctly.

Energy Savings and Home Value

A wood stove or gas fireplace can reduce annual heating costs by 10 to 30 percent by supplementing the primary HVAC system during the coldest months. The savings are most significant for homes heated with electric resistance (baseboard heat or an electric furnace), where electricity costs $0.12 to $0.15 per kWh in the SMECO service area. Heating the main living area with a wood stove instead of an electric furnace during a cold snap can save $5 to $15 per day in electricity.

A fireplace also adds to home resale value. Real estate data consistently shows that homes with fireplaces sell for 1 to 5 percent more than comparable homes without them. In the Southern Maryland market, where the median home price in 2026 is approximately $375,000 to $425,000, that translates to $3,750 to $21,250 in added value, though the realistic range for a well-installed wood stove or gas fireplace is $3,000 to $8,000 in perceived value at resale. Buyers consistently rank fireplaces among the most desirable home features in surveys, and in a market where rural homes sell on livability and charm, a fireplace is a tangible selling point.

Frequently Asked Questions

How much does it cost to install a wood stove in Southern Maryland? A wood stove installation costs $3,000 to $5,000 when replacing an existing stove, $4,000 to $8,000 when installing into an existing masonry chimney with a new liner, and $5,500 to $9,000 or more for a new installation with no existing chimney. The stove itself costs $1,000 to $4,000 depending on size and quality, and the chimney system and labor make up the rest.

Is it cheaper to install a wood stove or a gas fireplace? A wood stove installation is generally less expensive than a new gas fireplace when both start from scratch. A freestanding wood stove with Class-A chimney pipe costs $5,500 to $9,000 installed, while a new direct-vent gas fireplace with surround costs $5,000 to $15,000. However, a gas insert into an existing masonry fireplace ($3,500 to $8,000) can be comparable to or less than a wood stove insert ($3,000 to $6,500) depending on the chimney liner and gas line costs.

Do I need a chimney for a gas fireplace? No. A direct-vent gas fireplace vents through a small coaxial pipe that can exit through an exterior wall. This is why gas fireplaces can be installed in rooms and homes that have no chimney at all. A gas insert installed in an existing masonry fireplace does use the chimney, but with a small-diameter aluminum or stainless liner rather than the full masonry flue.

Will a wood stove heat my whole house? A wood stove rated at 50,000 to 80,000 BTU can heat 1,500 to 2,500 square feet in an open floor plan. In a typical Southern Maryland home, a wood stove in the main living area heats that room and adjacent rooms effectively but does not heat bedrooms at the far end of the house or upstairs rooms as well. Most homeowners use a wood stove as the primary heat source in the common areas and let the central HVAC handle the rest of the house at a lower thermostat setting.

Can I install a wood stove myself? Technically, Maryland allows homeowners to perform their own installations, but a permit and inspection are still required, and the installation must meet all code requirements for clearances, chimney height, hearth dimensions, and liner specifications. A professional installation costs $400 to $2,500 in labor and ensures the work passes inspection on the first visit. Given that an improperly installed wood stove is a house fire waiting to happen, professional installation is strongly recommended.

How often does a chimney need to be cleaned? The NFPA recommends annual chimney inspection and cleaning for all wood-burning appliances. A chimney serving a wood stove used regularly during heating season should be swept at least once per year, more often if you burn softwood or unseasoned wood, which produces more creosote. A chimney serving a gas fireplace should be inspected annually but typically does not need sweeping because gas produces no creosote.

What is the most efficient type of fireplace? Direct-vent gas fireplaces and modern pellet stoves are the most efficient at 75 to 90 percent efficiency. EPA-certified wood stoves run at 70 to 80 percent efficiency. Traditional open masonry fireplaces are the least efficient at 10 to 20 percent, most of the heat goes up the chimney. If you have an open fireplace and want efficiency, an insert (wood or gas) is the single best upgrade.

Do wood stoves make the house smell like smoke? A properly installed and operated wood stove should not make the interior smell like smoke under normal conditions. Smoke smell indoors usually indicates a draft problem (the chimney is not drawing properly), a leaking door gasket, or unseasoned wood producing excessive smoke. Proper chimney height, a good draft, dry seasoned hardwood, and a tight door seal prevent indoor smoke issues. During lighting and reloading, a brief whiff of wood smoke is normal and, for most wood stove owners, part of the appeal.

Is September really the best time to install? Yes. September and October are the ideal window for fireplace and stove installation in Southern Maryland. Contractors are available without the long wait times of the heating-season rush (November through January). Stove manufacturers and chimney component suppliers have full stock before the seasonal demand spike. The installation is completed and inspected before the first cold night, so the system is tested and ready when you need it. Waiting until November or December often means longer lead times on equipment, busier contractor schedules, and the possibility of going weeks into winter without supplemental heat while waiting for parts or installation dates.

Does a fireplace affect my homeowner's insurance? It can. Most insurance companies require that wood stoves and fireplaces be professionally installed, permitted, and inspected. An unpermitted installation may void fire-related coverage. Some insurers require a chimney inspection report before issuing or renewing a policy on a home with a wood stove. A few insurers charge a small surcharge ($25 to $100 per year) for homes with wood-burning appliances. Contact your insurer before installation to confirm their requirements.
