Fireplace installation involves choosing between wood-burning, gas, and electric models, then deciding whether to hire a contractor or handle simpler versions yourself
A fireplace is not one thing—it is a choice between three different systems that work differently, cost different amounts, and require different kinds of work to install. A wood-burning fireplace needs a chimney, a foundation, and a masonry contractor. A gas fireplace needs a gas line run to it and a vent, and can sometimes go into an existing fireplace opening. An electric fireplace is essentially a heater with a flame effect and plugs into an outlet. The right choice depends on what you have room for, what fuel you can access, and how much you want to spend upfront versus on fuel and maintenance over time.
Key Takeaways
- Wood-burning fireplaces cost the most to install (typically $3,000 to $5,000 or more) because they require a chimney, but they need no fuel hookup and work during power outages.
- Gas fireplaces cost less to install than wood-burning ones but require a licensed contractor to run a gas line and vent, and they need annual inspection and cleaning.
- Electric fireplaces are the cheapest to install and require only an outlet, but they produce heat only and cannot serve as a backup heat source during an outage.
- Building codes and permits vary by location; your contractor or local building department can tell you what is required before work begins.
- Installation timelines range from one day for electric to several weeks for wood-burning, depending on whether structural work or new utility lines are needed.
Wood-burning fireplaces: highest upfront cost, lowest fuel cost
A wood-burning fireplace requires a chimney, a firebox (the chamber where the fire burns), and a hearth (the floor in front of it). If you are building new or adding to an existing structure, a mason or chimney contractor will build these from scratch. If you have an existing fireplace, the contractor inspects it to see whether it can be rebuilt or whether the chimney needs replacement. The chimney must extend above the roofline and meet local building codes for height, clearance from combustibles, and flue size.
Installation typically takes two to four weeks because the chimney must be built in stages and inspected at each step. The cost ranges from $3,000 to $5,000 for a basic installation, and can exceed $8,000 if the chimney needs to be rebuilt or if the roof requires structural work to support it. Once installed, your only ongoing costs are wood (which you can gather or buy) and annual chimney cleaning and inspection, usually $150 to $300 per year. You will also need to have the chimney swept before each heating season to remove creosote buildup, which is a fire hazard.
Gas fireplaces: moderate cost, consistent heat output
A gas fireplace burns natural gas or propane and produces heat on demand. It requires a gas line run from your main gas supply (or a propane tank) to the fireplace location, and a vent that carries exhaust outside. Some gas fireplaces are direct-vent, meaning they pull air from outside and exhaust directly through an exterior wall, which is more efficient. Others are ventless, which means they burn gas inside your home and release exhaust into the room—these are not allowed in all states and require careful ventilation planning.
Installation cost ranges from $1,500 to $3,500, depending on how far the gas line must run and whether you need to vent through an existing chimney or create a new vent. A licensed gas fitter or HVAC contractor must do the work and pull a permit. The job typically takes one to three days. Once installed, you pay for the gas you burn (usually $10 to $30 per month during heating season, depending on use and local gas prices) and annual inspection and cleaning, around $100 to $200 per year. Gas fireplaces are reliable and produce steady heat, but they depend on the gas supply and electricity to run the ignition and controls.
Electric fireplaces: lowest installation cost and complexity
An electric fireplace is a self-contained unit that plugs into a standard outlet and produces heat via an electric element, with a flame effect created by LED lights or a video display. It requires no venting, no gas line, and no chimney. You can install one yourself if you have an outlet nearby, or hire an electrician if you want to add a dedicated circuit or outlet. Some models are freestanding; others insert into an existing fireplace opening or wall cavity.
Cost ranges from $300 to $1,500 depending on size and features, and installation is often same-day or not needed at all. There is no annual maintenance. The tradeoff is that an electric fireplace produces heat only—it cannot serve as a backup heat source during a power outage, and it will not heat a large space as efficiently as a wood or gas fireplace. Running one costs roughly $15 to $25 per month in electricity, depending on how often you use it and your local electricity rates.
Permits, inspections, and building codes
Most jurisdictions require a permit for fireplace installation, especially for wood-burning and gas models. The permit process involves submitting plans, having the work inspected at key stages (foundation, framing, before final closure), and a final inspection once the fireplace is complete. Electric fireplaces may not require a permit if they straightforward plug into an existing outlet, but check with your local building department first.
Building codes specify chimney height (usually at least 3 feet above the roof peak), clearance from combustible materials (typically 2 feet on sides and back, 1 foot above), hearth size and material, and venting requirements. Your contractor should know these rules for your area, but you can also call your local building department or check their website. Skipping the permit process can create problems when you sell the home, because a future buyer's inspector will flag an unpermitted fireplace, and you may be required to remove it or bring it into compliance.
Choosing between hiring a contractor and DIY installation
Wood-burning and gas fireplaces require licensed contractors—a mason for wood-burning, a gas fitter or HVAC technician for gas. These are not DIY projects because they involve structural work, utility connections, and code compliance that only licensed professionals can certify. Hiring a contractor costs more upfront but ensures the work is done safely and passes inspection.
Electric fireplaces are the only option for DIY installation. If the unit plugs into an existing outlet, you can unbox it and plug it in. If you want to hardwire it or add a new outlet, hire a licensed electrician—this is cheaper than hiring a contractor for a gas or wood fireplace, but still ensures the electrical work is safe and code-compliant. Never run a high-power appliance on an extension cord or overloaded circuit.
Timeline and disruption to your home
Electric fireplace installation takes hours to a day, with minimal disruption. Gas fireplace installation takes one to three days and involves running a gas line, which may require opening walls or drilling through exterior walls. Wood-burning fireplace installation takes two to four weeks and involves significant structural work—framing, masonry, roofing work, and multiple inspections. During this time, part of your home may be inaccessible, and there will be dust and noise.
If you are replacing an existing fireplace, the timeline is shorter because the structure is already in place. A gas fireplace can often fit into an existing wood-burning fireplace opening, which saves time and cost. Ask your contractor for a detailed timeline before work begins, including when inspections are scheduled and when you can expect the fireplace to be usable.

Frequently Asked Questions
Can I install a fireplace in an apartment or rental?
No, not without the landlord's written consent. Even then, most leases prohibit permanent installations. Electric fireplaces are sometimes allowed because they are portable and do not alter the structure, but check your lease first. Wood-burning and gas fireplaces require structural changes and are almost never permitted in rentals.
How much heat does a fireplace actually produce?
Wood-burning and gas fireplaces can heat a large room or small home zone effectively, though much heat escapes up the chimney. Electric fireplaces produce modest heat and work best for zone heating (warming one room) rather than whole-home heating. None should be your primary heat source unless you live in a mild climate or have backup heating.
What if my home does not have a chimney?
You can build one (expensive, for wood-burning), install a direct-vent gas fireplace (vents through an exterior wall), or choose an electric fireplace (no venting needed). A direct-vent gas fireplace is usually the most practical option if you want real heat without building a chimney.
Do I need to have my fireplace inspected every year?
Wood-burning fireplaces should be inspected and swept annually before heating season. Gas fireplaces should be inspected annually as well, though some years may only require a visual check. Electric fireplaces do not require professional inspection. Your contractor or a chimney sweep can perform these inspections.
What is the difference between a fireplace and a wood stove?
A fireplace is built into your home and vents through a chimney. A wood stove is a freestanding unit that also vents through a chimney but takes up floor space and is easier to remove. Wood stoves are more efficient at heating because less heat escapes, but they cost less to install than a fireplace if you already have a chimney.
