Instant Heat for Green Bay's Long, Cold Winters.

Most gas fireplace and insert installations in Green Bay run between roughly $4,000 and $10,000, depending on the unit, whether an existing gas line is already in place, and the venting path required. Converting an existing masonry fireplace into a gas insert with a WPS gas line already run to that side of the house tends to land on the lower end. New direct-vent installations in a remodel—especially ones requiring a new gas line from the meter—sit toward the higher end. A local hearth dealer will give you a firm number after seeing your specific setup.

Yes, and it's a common project in Green Bay's older neighborhoods—areas like Astor, Bay Settlement, and parts of the west side have plenty of mid-century homes with masonry fireplaces that were never great heat sources. A gas insert slides into that existing firebox and vents through a stainless liner run up the current chimney, so you keep the look of the fireplace while gaining real, controllable heat. Expect the job to run in a similar range to a full gas install, with the final cost depending mostly on whether the home already has a nearby gas line.

Either works, and which one makes sense usually comes down to where you live. Inside Green Bay proper, most homes already have natural gas service through Wisconsin Public Service, so adding a fireplace to an existing gas line is straightforward. Out in the more rural stretches of Brown County where WPS gas mains don't reach, propane from a local supplier is the standard fallback, either from an existing tank or a new one set specifically for the fireplace. Most gas fireplace models can be configured for either fuel—your installer sets the correct orifice for whichever you're running.

Most modern gas fireplaces will, but the details matter. Units with an intermittent pilot ignition (IPI) system typically run on a small battery backup that kicks in automatically when utility power drops, so the fireplace lights and operates normally until power is restored—as long as those batteries are fresh. A handful of manufacturers, including Valor, build fireplaces that generate their own power off the pilot flame itself, so there's no battery to remember at all. For Green Bay winters, where a lake-effect storm can knock out power for a day or more, ask your local dealer which ignition system a unit uses before you buy.

A gas fireplace is a fully built-in unit framed into a wall, typically used in new construction or a larger remodel. A gas insert is sized to slide into an existing masonry firebox, turning an old wood-burning fireplace into a sealed, efficient gas unit that vents through the existing chimney. A gas stove is a freestanding cabinet-style unit that sits on the floor, similar in footprint to a wood stove but running on gas. Green Bay's stock of older homes with existing masonry fireplaces makes the insert the most common upgrade path, while newer construction and additions tend to go with a built-in fireplace instead.

Yes. New gas fireplace installations typically require both a building permit and a gas piping permit through the City of Green Bay's Building Inspection Division, or the Brown County building office if you're outside city limits. The gas line connection has to be run or modified by a licensed plumber or gas fitter, which is one reason it's worth using a hearth dealer who coordinates the gas work, venting, and inspections together rather than juggling separate contractors yourself.

Vented gas fireplaces—direct-vent or B-vent—pull combustion air from outside and exhaust the byproducts back outside through a sealed pipe. Vent-free units burn gas directly into the room with no outside venting at all, which makes them more flexible to install but means moisture and trace combustion byproducts stay indoors. Wisconsin allows vent-free units when they're sized correctly for the room and equipped with an oxygen depletion sensor, but given how many months a year Green Bay homes stay sealed up tight against the cold, most local dealers steer customers toward direct-vent models—they don't add indoor humidity to a house that's already fighting condensation on cold-climate windows all winter.

Plan on an annual inspection, ideally in early fall before the unit sees heavy use through a Green Bay winter. A qualified technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior components. It's a lighter job than sweeping a wood chimney, but skipping it is how small issues—a sooting burner, a weak thermocouple—turn into no-heat calls in January. Local gas appliance service providers typically charge somewhere in the $125–$225 range for a standard annual visit.

Within city limits, gas is the practical default—natural gas service from WPS is already at most homes, and dense urban lots make wood storage and chimney maintenance a bigger hassle than in the countryside. Out in rural Brown County, wood stoves burning local oak, maple, birch, or aspen still make sense for households with access to a woodlot and a tolerance for the extra work, and they double as backup heat if the power goes out for an extended stretch. Pellet stoves split the difference on convenience but still need electricity to run the auger, which limits their use as true emergency heat. For most Green Bay homeowners inside the city, a direct-vent gas fireplace or insert delivers the most heat for the least ongoing effort.

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.

Four numbers tell you what fits: the front width, the front height, the back width, and the overall depth of your existing fireplace opening. Grab a tape measure, jot those down, and snap a photo of the wall—those two things do more to move your project forward than anything else you can do today.

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.

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.
