Instant Heat for Highwood's Lake-Effect Winters.

Most gas fireplace or insert installations in Highwood run roughly $4,000 to $10,500, depending on the unit and the venting path. A direct-vent gas insert going into an existing masonry fireplace with a nearby gas line already run tends to land on the lower end. A new built-in gas fireplace for a remodel—with framing, a fresh gas line from North Shore Gas service, and new venting through an exterior wall—sits toward the higher end. Given Highwood's older housing stock and often finished basements, running new gas line or venting through existing walls can add cost, so a local retailer's in-home visit is worth doing before you settle on a unit.

Yes, and it's a common project in Highwood's older bungalows and brick two-flats, many of which have an original masonry fireplace that's rarely used. A gas insert typically slides into that existing firebox and vents through the same chimney with a stainless liner, running about $4,500 to $8,500 depending on the insert and whether new gas line work is needed. It keeps the look of the original fireplace opening while trading ash, creosote, and chimney sweeping for a switch-operated flame.

Nearly every address in Highwood has natural gas service through North Shore Gas, so most homeowners simply tap into existing service—especially if you already have a gas furnace, water heater, or range. Propane is rarely necessary here given the density of the city and the reach of North Shore Gas lines, but it remains an option for detached structures or outbuildings where running a new gas line isn't practical. Most fireplace models can be configured for either fuel; your installer sets the orifice and regulator accordingly.

Most gas fireplaces with IPI (intermittent pilot ignition) run on a small battery backup that kicks in the moment ComEd power drops, so the fireplace lights on demand just like normal. That matters in Highwood, where winter storms off Lake Michigan and ice on the lines occasionally knock out power along the bluff for a stretch. Valor units take a different approach—their pilot's thermocouple generates its own electricity, so there's no battery to remember at all. Ask your local dealer which ignition system a specific model uses if outage performance matters to you.

A built-in gas fireplace is framed into a wall, which fits new construction or a full remodel. A gas insert drops into an existing masonry firebox and uses the chimney as its vent path—a natural fit for Highwood's stock of older homes with an original fireplace opening. A gas stove is a freestanding cast-iron or steel unit that sits on the floor and vents through a wall or existing flue, which works well in a smaller room or a home without an existing fireplace at all. For most Highwood remodels, the insert is the path of least resistance.

Yes. The Village of Highwood Building Department requires a permit for gas fireplace installations, along with a gas line permit whenever new piping is run, and the gas connection itself has to be completed by a licensed fitter. Most established hearth dealers coordinate the permit, the gas line work, and the final inspection as part of the installation quote, which is one of the real advantages of going through a trusted local installer instead of a big-box crew unfamiliar with Village requirements.

Illinois permits vent-free (unvented) gas fireplaces under specific room-size and ventilation rules, but for Highwood's colder, tightly sealed older homes, a direct-vent unit is almost always the better recommendation. Direct-vent models draw combustion air from outside and exhaust it back outside through a sealed pipe, which avoids adding moisture and combustion byproducts to an already well-insulated house in a 5A climate. Local dealers can walk through both options, but direct-vent is what most installers here actually put in.

Plan on an annual inspection, ideally in early fall before the fireplace sees regular winter use. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much lighter job than wood chimney sweeping but still important for safe operation. Local gas appliance service providers in the Lake County area typically charge $150 to $250 for this visit.

Highwood's compact lots, close-set homes, and older masonry chimneys make new wood-burning installations impractical for most properties in the city, and few local dealers stock wood units for this market as a result—wood-burning fireplaces here are largely limited to a handful of existing older homes rather than new installs. Gas, by contrast, works cleanly within tight clearances, needs no wood storage or ash removal, and ties directly into the North Shore Gas service already running to nearly every house in town. For Highwood homeowners weighing the two, gas is the practical default rather than a close call.

If it was installed more than 15 years ago, probably. Older gas fireplaces keep a standing pilot light burning all the time, and that little flame can cost a couple hundred dollars a year. Newer models use pilot-on-demand ignition—the pilot lights only when you use the fireplace and goes out when you turn it off.

Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.

If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.

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.
