Bring efficient gas heat to your Old Greenwich home.

In this part of Fairfield County, a gas insert into an existing masonry fireplace typically runs $5,500 to $9,500, while a new built-in direct-vent fireplace with fresh gas line work and framing runs higher—often $8,000 to $13,000 given the area's higher labor costs relative to national averages. Homes near the water that need to route venting around flood-zone elevation requirements or older stone chimneys sometimes land at the top of that range. A local dealer will give you a firm number after seeing the chimney and gas access in person.

Yes, and it's one of the most requested projects in Old Greenwich, where many colonials and capes built before 1960 still have their original brick fireplace. A gas insert with a stainless steel liner run up the existing flue is the standard approach, and it preserves the mantel and surround you already have while eliminating ash, creosote, and the smoke concerns that come with burning wood on a tight in-town lot. Expect $5,500 to $9,000 depending on chimney condition and whether the home is already piped for natural gas or needs a propane tank set.

If your street has natural gas mains—most of central Old Greenwich does, served by Southern Connecticut Gas—that's usually the simpler and cheaper long-term option, especially if your home already has gas for cooking or water heating. Properties closer to the Sound or on the edges of town that fall outside the gas main footprint typically run on propane, delivered and tanked by companies like Suburban Propane. Nearly every gas fireplace and insert on the market can be configured for either fuel, so the choice usually comes down to what's already running to your house.

Most direct-vent gas fireplaces with intermittent pilot ignition include a battery backup that keeps the unit firing during an outage—a real consideration in Old Greenwich, where nor'easters and coastal storms off the Sound regularly knock out power for a day or more. Valor's lineup takes a different approach: their pilot assembly generates its own electricity through the thermocouple, so the fireplace runs with no batteries at all. Given Eversource's residential electric rates, a battery- or self-powered gas fireplace is also a far cheaper backup heat source than running a portable electric heater during an outage.

A gas fireplace is a fully built-in unit, typically framed into a wall—the right call for a new addition or a room without an existing chimney. A gas insert slides into an existing masonry firebox and uses your current chimney as the vent path, which is the common choice in Old Greenwich's older housing stock. A gas stove is a freestanding cast-iron or steel unit that sits on the floor, useful in a den or sunroom that never had a fireplace to begin with. Most homeowners here with an original brick fireplace end up choosing an insert.

Yes—a building permit and a licensed gas-fitter's sign-off are both required through the Town of Greenwich Building Department, since Old Greenwich falls under the town's jurisdiction rather than having its own separate office. Because parts of Old Greenwich sit in FEMA-mapped flood zones given the low, 14-foot elevation near the Sound, venting height and equipment placement sometimes need to account for base flood elevation rules—something a local, permit-experienced installer will already know to check before work starts.

Vented (direct-vent) units draw combustion air from outside and exhaust it back outside through sealed pipe, and they're the standard, code-friendly choice for full-time use in a living room or den. Vent-free units burn without any outside venting and release some combustion byproducts into the room; Connecticut permits them under strict room-sizing and safety rules, but most Old Greenwich homeowners lean toward direct-vent for full-size heat output and because it avoids any indoor air quality trade-off in a well-sealed, older home. A local retailer can walk you through both if you're weighing the difference for a smaller secondary room.

Plan on an annual inspection, ideally before the heating season starts in the fall. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—usually $150 to $250 for the visit. This matters even in a mild-winter town like Old Greenwich, since salt air off the Sound can accelerate corrosion on venting components faster than it would further inland.

Wood stoves are uncommon here—Old Greenwich's tight, in-town lots, historic district considerations, and the general preference for low-maintenance systems mean very few homeowners install one as a primary heat source, though a handful still keep an open wood-burning fireplace going with local oak or maple for ambiance on cold nights. For anyone wanting real heat output rather than occasional atmosphere, gas is the far more practical fit in this town: no wood storage, no chimney smoke drifting over close-set neighbors, and heat on demand at the flip of a switch.

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.

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.

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.

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.
