Every Project Starts From One of These Five Situations
Reliable heat for one of Wisconsin's coldest counties.
Columbia County sits in south-central Wisconsin where the Wisconsin River cuts through the Baraboo Hills, spanning Portage, Wisconsin Dells, Lodi, Poynette, Pardeeville, Cambria, and a scatter of farming townships in between. At Climate Zone 6A, winters bring lows near 10°F and a heating season closer in length and severity to Minneapolis than to anywhere south of the Wisconsin-Illinois line. Furnaces run for months, and a lot of local homeowners want a supplemental heat source that doesn't depend on trudging out to a woodpile every few hours.
Oak, maple, birch, and aspen are the wood species most local households know from splitting and stacking firewood, and plenty of Columbia County homes still keep a wood stove going as backup heat or for the cabin at the Dells. But for a main living room or a primary heat zone, gas has become the more common upgrade—no ash, no chimney sweep schedule, and heat at the flip of a switch. In town, natural gas service through Alliant Energy covers much of Portage and the surrounding municipalities; out in the county's rural townships, propane from regional suppliers fills the gap. Either way, the county has no air quality non-attainment issues or burn-curtailment periods to navigate, which makes gas installation and permitting comparatively straightforward.

Frequently Asked Questions
How much does a gas fireplace installation cost in Columbia County?
Most gas fireplace and insert installations in this part of Wisconsin run somewhere between $4,000 and $10,000, with the spread driven mainly by venting complexity and whether new gas line work is needed. A direct-vent insert dropped into an existing masonry fireplace that already has gas nearby lands on the lower end. A new built-in unit for a remodel or an addition—with fresh framing, venting, and a gas line run from the meter—sits toward the higher end. Homes on propane that need a new tank set will add to that. A local dealer will give you a firm number after seeing the space, but that range is a reasonable starting point for budgeting.
Can I convert my existing wood fireplace to gas?
Yes, and it's a common project for older farmhouses and homes in Portage and Lodi with a masonry fireplace that's rarely used. A gas insert goes into the existing firebox, running a stainless liner up the current chimney, so you keep the look of the fireplace while gaining real, consistent heat. If the home already has natural gas or a propane line nearby, the job is mostly about the insert and venting; if not, running gas to the fireplace adds to the cost. Either way, it's usually less invasive than people expect, since the existing chimney does most of the work.
Do I need natural gas, or does propane work for a gas fireplace?
Both work fine—the fireplace itself can be configured for either fuel. Inside Portage and the villages along the natural gas corridor, Alliant Energy service makes hookup simple if the home already has gas appliances. Out in Columbia County's rural townships and around the lake and cabin properties near Wisconsin Dells, propane is the more common route, either through an existing tank or a new tank set by a local propane supplier. Your installer will set the correct orifice and regulator for whichever fuel you're running—it's a configuration choice, not a limitation on which fireplace models are available to you.
Will a gas fireplace still work if the power goes out?
Most will, depending on the ignition system. Units with intermittent pilot ignition (IPI) run on a battery backup—typically a few AA batteries inside the unit—that kicks in automatically and lets the fireplace light and run as normal during an outage, as long as the batteries are fresh. A handful of manufacturers, Valor among them, go a step further: their pilot assembly generates its own electricity through the thermocouple, so the fireplace needs no batteries at all. For a Columbia County winter storm that knocks out power for a day or two, that distinction matters—ask your local dealer about the ignition system on any model you're considering.
What's the difference between a gas fireplace, gas insert, and gas stove?
A gas fireplace is a fully built-in unit framed into a wall—typical for new construction or a remodel where there's no existing fireplace. A gas insert is built to slide into an existing masonry fireplace opening, using the current chimney as a chase for the vent liner. A gas stove is a freestanding cabinet unit that sits on the floor, similar in footprint to a wood stove but running on gas. For the many older homes around Portage and Cambria with an existing wood fireplace that's underused, an insert is usually the right fit. Homes without an existing fireplace opening are better matched to a built-in unit or freestanding stove.
Do I need a permit to install a gas fireplace in Columbia County?
Generally yes—a building permit and a gas line permit are both typically required for a new gas fireplace or insert installation, whether you're in Portage city limits or unincorporated county land. The gas piping itself needs to be run or inspected by a licensed gas-fitter. Most established hearth dealers handle the permitting and inspection scheduling as part of the installation, which is one of the practical reasons to go through a dealer rather than a big-box purchase with a handyman install.
Vented vs. vent-free gas fireplaces—what's the difference?
Vented (direct-vent) gas fireplaces pull combustion air from outside and exhaust the byproducts back outside through a sealed pipe—they're the cleanest and most universally code-compliant option, and they hold up well in a climate like Columbia County's where the fireplace may run for hours at a stretch through a long winter. Vent-free units burn without any outside venting at all, releasing a small amount of water vapor and combustion byproducts into the room; they're legal in Wisconsin but come with strict room-sizing and ventilation rules. For most homes here, especially anything used as a primary heat source rather than occasional ambiance, direct-vent is the standard recommendation. Ask a local dealer to walk through both if you're weighing the tradeoff.
How often does a gas fireplace need to be serviced?
An annual inspection is the standard recommendation, ideally before the heating season starts in the fall. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much quicker job than a wood-stove chimney sweep, but just as important for safety and for keeping the unit running efficiently through a long Wisconsin winter. Expect to pay roughly $150 to $250 for a routine service call from a local hearth or HVAC provider.
Gas vs. wood—which makes more sense for a Columbia County home?
Wood—oak, maple, birch, and aspen are all common locally—burns hot, costs less if you're cutting or buying it locally, and keeps working when the power is out, which matters here through winter storms. Gas trades that off for convenience: no hauling, no ash, no chimney maintenance schedule, and heat that turns on with a switch or a wall thermostat. Given the county's long heating season, plenty of households end up with both—a wood stove or fireplace for backup heat and ambiance, and a gas unit in the main living space for daily, low-effort warmth. If you already have a functioning wood setup and just want easier day-to-day heat, gas is usually the addition that gets used the most.
Why is a fireplace insert so efficient?
An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.
What's the difference between an insert and a zero-clearance fireplace?
An insert is a fireplace that slides into a pre-existing wood-burning fireplace—if you don't have one, there's nothing to insert it into. A zero-clearance fireplace is built into a framed wall, which makes it the answer for remodels and new construction. Simple test: existing masonry fireplace means insert; blank or framed wall means zero-clearance.
Does a fireplace add value to my home?
On average, a fireplace adds back to the home about the same amount you spent installing it. Add the monthly savings from heating the rooms you actually use instead of the whole house—often hundreds of dollars a year—and the value case is strong before you even count what a fire does for how your family uses the room.
Can a fireplace actually lower my heating bill?
Yes—by creating a comfort zone. A furnace heats every square foot of the house just to warm the one room you're in; a gas fireplace on low burns roughly a sixth of the gas a typical furnace does. Set the furnace around 55–60 degrees as a baseline, then heat the rooms your family actually uses. Families who heat this way commonly save $20–$60 a month.
