Real heat for cold nights on the Chain O'Lakes.

Every job is a little different, but in this part of McHenry County a direct-vent gas insert into an existing masonry fireplace typically runs $4,000 to $8,000, while a new built-in gas fireplace with fresh venting and gas line work in a remodel or new build runs closer to $7,000 to $12,000. Homes already on Nicor Gas's line with a fireplace nearby usually land on the lower end; lake-house properties needing a new propane tank or a longer gas line run from the street tend to land higher. A local dealer will give you a firm number after walking your specific home.

Yes, and it's a common project for the older lake cottages around Pistakee Highlands that were built with a wood-burning masonry fireplace decades ago. A gas insert slides into that existing firebox and uses a stainless liner run up your current chimney, so you keep the look of the original fireplace while gaining real heat output and an on/off switch. Homes already connected to Nicor Gas are the simplest conversions; if your property runs on propane, the insert just needs to be set up for that fuel instead—either way, the existing chimney does most of the work.

Either works. Nicor Gas provides natural gas service through most of McHenry County, and if your Pistakee Highlands home already has a gas water heater or furnace, adding a fireplace onto that line is usually the easiest path. Homes on the outer edges of the subdivision or along the water that sit off the main gas line typically run on propane instead, with a tank set on the property by a local supplier. Nearly every gas fireplace on the market can be configured for either fuel—your installer sets the correct orifice and regulator for whichever you have.

Most will, provided you choose a unit with a battery-backed ignition. Storms off the lake can knock out ComEd or Rock Energy Cooperative service for hours at a time in winter, and a fireplace with IPI (intermittent pilot ignition) switches over to AA batteries automatically so it keeps lighting on demand. Valor's gas fireplaces go a step further—the pilot's thermocouple generates its own electricity, so there's no battery to remember at all. For a lake house that sits empty during the week, that kind of no-maintenance backup heat is worth asking about specifically.

A gas fireplace is a fully built-in unit framed into a wall—the right call for new construction or a remodel without an existing hearth. A gas insert is built to slide into an existing masonry firebox, which fits a lot of the older homes around Pistakee Highlands that still have their original wood-burning fireplace. A gas stove is a freestanding cabinet-style unit that sits out in the room and vents through a wall or existing flue—a good option for smaller lake cottages where a full fireplace remodel isn't practical. A local dealer can tell you which fits your specific floor plan.

Since Pistakee Highlands is unincorporated, permitting for new gas fireplace and gas line work runs through the McHenry County Building Division rather than a city hall. You'll need both a building permit for the appliance and a mechanical/gas permit for the line work, and any propane tank installation typically requires its own approval from the supplier and county fire code. Most established hearth dealers pull these permits as part of the installation, so it's rarely something you have to manage yourself.

Vented (direct-vent) units draw combustion air from outside and exhaust it back outside through a sealed pipe—they're the standard, code-friendly choice almost everywhere, including McHenry County. Vent-free units burn directly into the room air with no outside venting; they're legal in Illinois but come with strict room-size and ventilation rules, and they release some moisture and combustion byproducts into the house. For a lake-area home where humidity and window condensation are already a winter concern, direct-vent units are the more common and generally recommended choice—ask your local dealer to walk through both if you're weighing it.

Plan on an annual inspection, ideally before the cold sets in each fall. A technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass and interior—a much lighter job than chimney sweeping on a wood stove, but just as important for safety. Expect to pay somewhere in the $150 to $250 range for a standard annual visit from a local service provider.

Wood-burning options are genuinely rare in Pistakee Highlands—the subdivision's small lots and lack of adjacent forest land for cutting permits make it impractical for most homeowners, so the real comparison locally is gas versus electric. Gas delivers real flame and enough heat output to matter on a 13°F January morning, plus battery-backup ignition that keeps working through a Rock Energy Cooperative or ComEd outage. Electric fireplaces cost less to install, need no gas line or venting at all, and work fine for ambiance or light supplemental warmth in a weekend lake cottage, but they're only as reliable as the power grid and won't keep a room warm through an extended outage. For full-time residents dealing with real Illinois winters, gas is usually the better primary heat source; for a lightly used vacation property, electric can be the simpler add.

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.

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.

For an average home—covering the fireplace, the vent pipe, and basic installation—a budget between $3,900 and $5,500 gives you a lot of options across wood, gas, and pellet. By the time you add finish work, gas line, and electrical, the average complete installation lands between $5,000 and $12,000 all-in. In a remodel or new build, a good rule is to put about 2.5% of the total project cost toward the fireplace.

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.
