Warm up your Hillandale home without the wood pile.

Most gas fireplace and insert installations in Hillandale run $4,000 to $9,500, depending on the unit and how much gas line and venting work is involved. A direct-vent insert going into an existing masonry fireplace shell—common in Hillandale's older duplexes—with a Washington Gas line already nearby tends to land on the lower end. A new built-in gas fireplace in a remodeled room, requiring a fresh branch line and full direct-vent penetration through an exterior wall, sits toward the higher end. A local dealer will confirm exact pricing after seeing your home.

Yes, and it's one of the more common projects in this part of Montgomery County. Many Hillandale homes built in the 1940s through 1960s have a masonry fireplace that was originally designed for wood but sees little or no use today—full wood-burning setups aren't practical on most of these smaller lots. A gas insert typically runs $4,000 to $8,000 installed, using a stainless liner through the existing chimney as the venting path. It keeps the look of your original hearth while giving you real, on-demand heat without cordwood storage or ash cleanup.

If your home is on natural gas already—which is the case for most of Hillandale's 20783 and 20903 zip codes through Washington Gas—adding a fireplace is usually a straightforward branch-line extension. Propane is really only a consideration for homes with unusual gas access issues or specific unit preferences, since natural gas service is well established throughout this part of Montgomery County. Your installer can configure most fireplace models for either fuel if propane turns out to be the better fit for your situation.

Most direct-vent gas fireplaces with intermittent pilot ignition (IPI) include a battery backup that keeps the unit running when Pepco power drops—which matters in Hillandale given how quickly summer storms and winter ice events can knock out power in this part of Montgomery County. Valor fireplaces take a different approach: the pilot's thermocouple generates enough electricity to run the unit with no batteries at all. Either way, ask your local dealer which ignition system a given model uses before you decide.

A gas fireplace is a fully built-in unit framed into a wall—the right choice for new construction or a room without an existing hearth. A gas insert drops into an existing masonry fireplace opening and uses the chimney as its vent path, which fits a lot of Hillandale's older housing stock. A gas stove is a freestanding cabinet-style unit that sits on the floor and vents through a wall or existing flue—a good option in a duplex or rowhouse with limited hearth space. Most Hillandale homeowners with an existing fireplace opt for an insert; homes without one usually go with a built-in unit or a stove.

Yes. Hillandale is unincorporated, so building and gas permits go through the Montgomery County Department of Permitting Services (DPS) rather than a city office. New gas line work requires a licensed gas fitter, and the venting and framing require a building permit and inspection. Most established local hearth dealers handle the DPS paperwork as part of the installation, so you're not coordinating separate trades yourself.

Vented, direct-vent units are the standard recommendation for Hillandale homes and what most local dealers install by default—they draw combustion air from outside and exhaust it back outside, so there's no debate about indoor air quality. Vent-free units are technically permitted under Maryland code with strict room-sizing and ventilation requirements, but given how tight the floor plans are in a lot of Hillandale's duplexes and garden apartments, a sealed direct-vent unit is almost always the better fit and the one installers here recommend first.

Plan on an annual inspection, ideally in early fall before regular use starts. A technician checks the burner, pilot assembly, venting, and any gas connections, and cleans the glass and interior. This is a lighter lift than wood-stove chimney sweeping—most local service providers in the Hillandale and Silver Spring area charge in the $150 to $250 range for a standard annual visit.

Gas gives you real heat output—enough to genuinely warm a room on a 25°F night—plus battery or thermocouple backup that keeps working through a Pepco outage. Electric fireplaces cost far less to install (typically under $1,200, often just a matter of plugging into an existing outlet) and offer flexibility for renters or rooms without gas access, but they add to your Pepco bill at 18.74 cents per kWh and stop working the moment the power does. Wood is rarely practical here given lot sizes and chimney setups, so most Hillandale homeowners are really choosing between these two. If you want dependable heat during storms, gas wins; if you want a low-cost ambiance upgrade with no venting work, electric is the simpler path.

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 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.

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.
