Gas warmth built for Wildwood's wooded lots and cold snaps.
With a solid, moderate heating season and winter lows averaging 22°F, Wildwood doesn't need extreme cold-weather gear—it needs a fireplace that lights reliably on the nights it dips into the teens. I'll match you with a trusted local dealer who knows the gas line work and venting for this stretch of St. Louis County.
Every Project Starts From One of These Five Situations
Convenient heat for a growing St. Louis suburb.
Wildwood sits in climate zone 4A at 765 feet, with an average winter low of 22°F and a solid, moderate heating season—a real Midwest winter, but not the extended deep-freeze you'd get farther north. What's distinctive about Wildwood isn't the climate so much as the housing stock: this is one of the newest incorporated cities in St. Louis County, built out largely on wooded acre-plus lots since the mid-1990s, and a lot of that construction went in with direct-vent gas fireplaces as the standard feature rather than a traditional wood-burning masonry chimney.
That's part of why gas has become the default fireplace fuel here even though oak, hickory, walnut, and maple grow all over the city's namesake wooded acreage—wood-burning setups just aren't common in Wildwood's newer subdivisions, and most builders and HOAs steer new construction toward gas instead. Spire provides natural gas service across most of the city, though some of the more rural western pockets near Highway 109 run on propane. Union Electric (Ameren Missouri) serves electric needs at roughly 12.56 cents per kWh, which matters if you're weighing a gas insert's battery-backed ignition against an all-electric unit for a bedroom or bonus room.

Frequently Asked Questions
How much does a gas fireplace installation cost in Wildwood?
Most Wildwood installations fall between roughly $3,500 and $10,000. On the low end, a direct-vent insert going into an existing prefab firebox—common in the city's post-1995 subdivisions—with a gas line already stubbed nearby is a relatively quick job. On the high end, a new built-in fireplace for a remodel or an addition, especially on the larger wooded lots where the gas line has to run farther from the meter, pushes toward the top of that range. If your home is in one of the pockets served by propane rather than Spire, tank setup adds to the cost. A local dealer can quote a firm number after walking the space.
Can I convert my existing wood fireplace to gas?
Yes, and it's a common request from owners of Wildwood's older homes—the ones built before the city incorporated in 1995, when a traditional wood-burning masonry fireplace was more standard. A gas insert typically drops into that existing firebox using a stainless liner run up the current chimney, which is usually simpler and cheaper than the venting work required in newer homes that were never built with a masonry chimney at all. Expect the conversion to run in a similar range to a standard install, with the final number depending on whether the gas line needs to be extended to reach the fireplace location.
Do I need natural gas service, or should I plan on propane?
It depends on where in Wildwood you are. Spire's natural gas network covers most of the city's established neighborhoods, so if your water heater or range already runs on natural gas, adding a fireplace is usually a straightforward tie-in. Out toward the more rural western edges of the city, some homes rely on propane instead, which means budgeting for a tank and a line run if one isn't already in place. Either fuel works fine in a modern direct-vent fireplace—your installer configures the burner orifice for whichever gas you've got.
Will my gas fireplace still work if the power goes out?
Most will, and it's worth checking before you buy given that ice and windstorms occasionally knock out power across St. Louis County. Units with IPI (intermittent pilot ignition) run their ignition system off AA battery backup that kicks in automatically when Union Electric service drops. Valor fireplaces take a different approach entirely—the pilot's thermocouple generates its own electricity, so there's no battery to remember at all. If backup heat during an outage matters to you, ask your local dealer which ignition system is on any model you're considering.
What's the difference between a gas fireplace, insert, and stove?
A gas fireplace is a built-in unit framed into a wall—the default in most of Wildwood's newer construction. A gas insert fits inside an existing masonry firebox, which is the more relevant option for the city's pre-1995 homes that started out with a wood-burning fireplace. A gas stove is freestanding on a hearth pad, similar in footprint to a wood stove but running off a gas line or propane tank instead of cordwood—a good fit for a bonus room or finished walkout basement where there's no existing chimney chase to work with.
Do I need a permit to install a gas fireplace in Wildwood?
Yes. You'll need a building permit through the City of Wildwood, plus a separate gas line permit since that work requires a licensed gas-fitter or plumber. Established hearth dealers who work regularly in western St. Louis County typically coordinate both permits and the final inspection as part of the installation, so you're not managing two separate approvals and two trades on your own.
Vented vs. vent-free gas fireplaces—what should I know?
Vented (direct-vent) units draw combustion air from outside and exhaust it back outside through sealed pipe, which makes them the safer, code-compliant choice everywhere, including Missouri. Vent-free units are legal here and burn directly into the room, but they come with strict minimum room-size and ventilation requirements. Wildwood doesn't carry any of the air-quality non-attainment restrictions you'd see in some larger metro areas, so vent-free is a viable option in a well-sized room, but most local dealers still recommend direct-vent as the default for anything used regularly.
How often does a gas fireplace need to be serviced?
Plan on an annual inspection, ideally in late summer or early fall before you're relying on it through the coldest part of the year. A technician checks the burner, pilot assembly, gas connections, and glass, and confirms the venting is still sealed and clear—worth doing given how many Wildwood homes sit surrounded by mature oak and walnut trees that can drop debris near exterior vent terminations. A standard service visit typically runs $150 to $200.
Gas vs. electric—which makes more sense for a Wildwood home?
Gas wins for whole-room heat output and ambiance closest to a real flame, and with Spire service covering most of the city, running cost per BTU is usually lower than electric resistance heat. Electric fireplaces, drawing power from Union Electric at about 12.56 cents per kWh, make more sense for secondary rooms, finished basements, or condos and townhomes in Wildwood's newer developments where running a gas line or venting isn't practical—they install for a fraction of the cost and need no venting at all, just an outlet. Wood-burning setups, by contrast, are genuinely uncommon here; most of Wildwood's housing stock was built after the shift toward gas and electric hearth products, so a wood stove is rarely the practical choice even with plenty of oak and hickory on the surrounding lots.
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.
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.
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.
