One Page, Every Gas Fireplace Option We Install

Gas fireplaces come in four distinct forms, and choosing between them is the real decision. The installation part is our job. Here’s the complete picture of what we install across Maryland, Virginia, and DC, all in one place. We install and service gas units from trusted fireplace brands like Heat & Glo, Majestic, and Real Fyre.

Gas Fireplace Inserts

An insert slides into your existing masonry firebox and turns an open, inefficient wood fireplace into a sealed, high-efficiency gas heater. This is our most popular gas installation, and it’s what most Rockville and Bethesda homeowners mean when they ask about converting to gas.

The appeal is easy to explain. Inserts burn clean with no ash or creosote to deal with, built-in blowers push heat into the room instead of up the flue, and modern units run from a remote or a wall thermostat. Every insert we install includes a properly sized liner run through your existing chimney, installed to NFPA 211 and the manufacturer’s specification. That’s what keeps the warranty valid and the draft right.

Gas Log Sets

Gas logs are the simplest conversion: a realistic ceramic log set installed in your existing open fireplace. You keep the traditional open-hearth look and lose the wood hauling and ash shoveling forever. Modern sets are convincing, with glowing embers and flickering flames, in styles from oak to birch to contemporary.

The key decision with logs is vented versus ventless. Vented sets look most realistic and exhaust through your chimney, which needs to be inspected and functional. Ventless sets put more heat in the room and don’t use the flue, but they face stricter regulations and aren’t right for every home or every jurisdiction. We’ll tell you honestly which your home supports, including when the answer is neither and an insert makes more sense.

Free-Standing Gas Stoves

A free-standing gas stove is the answer when you want fire in a room that never had one. They vent through a wall or roof with their own pipe, so no existing chimney is needed. A corner of the family room, a finished basement, a four-season porch, all of them become candidates. They put out serious, consistent heat for their size, in styles from cast iron traditional to modern matte black.

Placement comes down to manufacturer clearances and venting routes, which we confirm during the consultation. It’s usually more flexible than homeowners expect.

Factory-Built Gas Fireplaces

A factory-built gas fireplace is a complete engineered fireplace system installed where no masonry fireplace exists. New construction, additions, or that blank living room wall. The firebox, venting, and surround arrive as a matched, tested system, which makes installation faster and performance predictable. Compared to building a masonry fireplace, a factory-built unit delivers the architectural centerpiece at a fraction of the cost and timeline, with modern efficiency built in.

Which Gas Fireplace Is Right for Your Home?

If you have a wood fireplace and want heat and efficiency, look at an insert. If you have a wood fireplace and want the open-hearth look with zero work, gas logs. No fireplace in the room and no appetite for construction? A free-standing stove. Building or remodeling and want a true built-in? Factory-built.

Still torn between two? That’s normal, and it’s exactly what the consultation visit sorts out, with your actual room, chimney, and gas line in front of us.

How Gas Installation Pricing Works

The four options above span a wide cost range. A log set is a very different project from a full insert conversion with a new liner. So we price the way we always do: honestly, in writing, after seeing your home. A consultation visit runs $99 to $150 depending on location and gets credited back toward the project. If your chimney’s condition is a factor, and for inserts and vented logs it always is, a $279 Level 2 inspection with video scan gives the full picture. You’ll leave with real numbers, usually for more than one option, because not every home and budget lands on the same answer.

Common Questions About Gas Fireplace Installation

Can any wood fireplace be converted to gas?

Almost any structurally sound masonry fireplace can take an insert or log set, provided gas service can reach it and the chimney passes inspection. The inspection is where we confirm both, before you’ve committed to anything.

What’s the difference between vented and ventless gas logs?

Vented logs exhaust through your chimney and look most realistic. Ventless logs vent into the room with more heat output, but tighter regulations and suitability limits. Local code and your home’s ventilation decide which is appropriate.

Do gas fireplaces need maintenance?

Yes. An annual service keeps the valve, pilot assembly, burner, and venting safe and efficient. Our gas fireplace service and inspection is $399, with additional fireplaces at $329.

How long does installation take?

Most gas insert, log, and free-standing stove installations finish in half a day to a day once the unit and any gas line work are ready. Factory-built installations run longer since framing and finishing are involved.

Do I need a permit?

Gas appliance installations require permits in most Maryland, Virginia, and DC jurisdictions. We install to code and manufacturer specification, so permitting is part of the process rather than a surprise.

This was the second year that I had my chimney serviced by Jacob Ben of Sweep Your Chimney. Last year Jacob and his crew repointed the outside of my two chimneys and presure washed them. The result was beautiful. They also treated the firebox and inside of the chimney for creosote and swept the chimney. This year, Jacob repointed the inside of the chimney and replaced the damper. I am always suspicious when a a chimney company tries to upsell me with expensive services I don't think I need (such as continuously replacing the lining of the chimney). Although Sweep Your Chimney did suggest extra work, I was convinced that it was necessary. It did not try to sell me anything I didn't need, such as relining the chimney, and I thought that the prices were reasonable. I am happy that my chimney is now in excellent condition.

I really appreciated how thorough and professional Sweep Your Chimney was. Jacob provided a professional and thorough estimate and followed up after the repair work was done to ensure my satisfaction. Armando and his team did an excellent job replacing the crown on my chimney, repairing mortar joints, where necessary and applying waterproofing. They went above and beyond to identify and fix a gutter problem during a torrential rain downpour which may have been causing water to enter my house between the chimney and foundation. I am so grateful with how well they took care to resolve my problem and I would gladly recommend them to anyone.

Kyle was very professional, extremely knowledgable and personable. We are grateful for his inspection and gave our family peace of mind for safety. His broad wealth of knowledge was not limited to only gas fireplace cleaning and maintenance, but also wood burning units. Would absolutely welcome him back for annual inspections or any concerns regarding our fireplace. Two thumbs up and 5-stars.

I knew my chimney needed work, and the crew at Sweep Your Chimney gave me the best experience I've had in months. They performed an honest chimney inspection, did a solid chimney cleaning, and installed a new chimney cap that looks perfect and keeps the weather out. The cap fits so well and the workmanship is top‑notch. I’m very happy with the service and would recommend them for any chimney work.

Jacob, Eden and Kyle make a great team. We were very happy with the service which included both repairs to the chimney and installation of a gas fire place. The team was polite, professional and on time. They worked with our schedule and requirements. And they followed up promptly when we have a post install problem (user error). We’d work with them again and have recommended them to others.
