Real Heat, No Wood Splitting Required.
Instant, reliable heat for Cottage Grove's long Dane County winters. Find the right gas fireplace or insert and get matched with a trusted local dealer.
Every Project Starts From One of These Five Situations
Consistent Warmth Through a 7,100-Degree-Day Winter.
Cottage Grove sits just east of Madison in Dane County, at an elevation of about 908 feet, where winter lows average 12°F and the area faces a heavy winter heating load—comparable to Duluth, MN and closer to that than to most of the Midwest. Wood heat has deep roots here, with oak, maple, birch, and aspen all common in local woodlots, but gas has become the default choice in newer subdivisions and remodels around the village, where homeowners want dependable warmth without hauling and splitting cordwood every fall.
Natural gas service within Cottage Grove village limits is typically supplied through Alliant Energy (Wisconsin Power & Light), which also provides electric service here alongside Rock Energy Cooperative. Homes in unincorporated parts of Dane County outside the gas main tend to rely on propane instead. Either way, a modern gas fireplace or insert gives you heat at the flip of a switch, pairs cleanly with a forced-air furnace for zone heating on the coldest nights, and—with the right ignition system—can keep running through a winter power outage.

Frequently Asked Questions
How much does a gas fireplace installation cost in Cottage Grove?
A typical gas fireplace installation in Cottage Grove runs roughly $4,500 to $10,500 depending on the unit, the venting path, and whether new gas line work is required. A direct-vent insert going into an existing masonry fireplace with a gas line already nearby sits toward the lower end. A new built-in gas fireplace for a remodel or addition—with framing, venting through an exterior wall, and a fresh gas line run from the meter—lands in the middle to upper range. Homes needing a propane tank setup or a longer gas line extension from the street will run higher. A local retailer can give you a firm number after an in-home walkthrough.
Can I convert my existing wood fireplace to gas?
Yes, and it's a common project for older Cottage Grove homes with a masonry fireplace that's rarely used because splitting and hauling wood has gotten old. Most conversions install a gas insert into the existing firebox, running a stainless liner up the chimney you already have. Expect $4,500 to $8,500 depending on the insert and whether the home already has a gas line nearby. It keeps the look of your original fireplace while giving you real, consistent heat instead of an occasional weekend fire.
Do I need natural gas to install a gas fireplace, or can I use propane?
Either works. Inside Cottage Grove village limits, natural gas is typically available through Alliant Energy (Wisconsin Power & Light), and if your home already has a gas furnace or water heater, adding a fireplace is usually straightforward. For homes on the outskirts of the village or elsewhere in unincorporated Dane County without gas mains, propane is the standard fallback, supplied by a regional propane provider with either a buried or above-ground tank. Most gas fireplace models can be set up for either fuel—your installer just adjusts the orifice and regulator to match.
Will my gas fireplace work during a power outage?
Most modern gas fireplaces will, which matters here given how often Dane County sees winter ice storms take down power lines for a day or more. Units with intermittent pilot ignition (IPI) run on a battery backup—usually AA batteries inside the unit—that kicks in automatically when the power drops, so the fireplace still lights on demand. Valor fireplaces go a step further: they generate their own electricity from the pilot's thermocouple, so there are no batteries to remember at all. If backup heat during outages matters to you, ask your local dealer which ignition system a given model uses before you buy.
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, typically used in new construction or a remodel where there's no existing fireplace. A gas insert is built to slide into an existing masonry firebox, sealing it up and using your existing chimney as the vent path. A gas stove is a freestanding cast-iron or steel unit that sits on the floor like a wood stove but burns gas. For Cottage Grove homes with an underused wood fireplace, an insert is usually the easiest upgrade. New rooms or additions without an existing chimney are better suited to a built-in unit or a freestanding stove.
Do I need a permit to install a gas fireplace in Cottage Grove?
Yes—the Village of Cottage Grove requires a building permit for the installation, and a separate gas permit is needed for the fuel line work, which must be done by a licensed gas fitter. Most established hearth dealers handle both permits as part of the job, which is one of the real advantages of going through a certified local installer rather than a handyman: they coordinate the gas line, venting, and inspection sign-off as one job instead of leaving you to manage separate trades.
What's the difference between vented and vent-free gas fireplaces?
Vented (direct-vent) gas fireplaces pull combustion air from outside and exhaust the byproducts back outside through a sealed pipe—they're the safest option and the one nearly every Cottage Grove installer will recommend. Vent-free units burn fuel directly into the room without any outside venting; they're legal in Wisconsin but come with strict room-sizing rules and oxygen depletion sensors, and they add moisture to the indoor air—a real consideration in tightly built, well-insulated homes common in this climate zone, where excess humidity can lead to window condensation and mold risk over a long heating season. For that reason, direct-vent units are by far the more common choice locally.
How often should my gas fireplace be serviced?
Plan on an annual inspection, ideally in early fall before the first cold snap. A certified technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior. It's a shorter visit than a wood chimney sweep, but skipping it is how pilot and ignition problems go unnoticed until the coldest week of the year. Local gas appliance service providers typically charge $150 to $250 for this annual visit.
Gas vs. wood—which is right for my home?
Wood is deeply practical around Cottage Grove, where oak, maple, birch, and aspen are all readily available from local woodlots, and a wood stove keeps producing heat with no electricity needed during an ice-storm outage. Gas trades that self-sufficiency for convenience: instant on-off operation, no ash or creosote to manage, and steady output that pairs well with central heating during a long, demanding winter heating season. Many homes in the area end up with both—gas as the everyday, low-effort heat source in the main living space, and a wood stove or insert kept in reserve for extended outages or the ambiance of a real fire.
Can I put a TV above my fireplace?
Yes—with an asterisk. Fireplaces are hot and TVs don't like heat. Either put a mantel between them to deflect rising warmth, or choose a fireplace with heat-management technology that creates a cool zone on the wall above—the wall stays around 125 degrees, barely warm, while the room still gets full heat. If you like clean lines and don't want a mantel, heat management is the answer.
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.
What is an in-home preview and do I need one?
It's a visit where a hearth professional measures your space, confirms the model you picked actually works in your home, and walks the specs—framing, gas line, venting, finish work—before anything is ordered. Some details you just can't know until you see the house. Never make a down payment without one; it's the single most-skipped step that burns buyers.
