If you have a wood-burning fireplace in your Northern New Jersey home, you’ve probably experienced the full range of emotions it produces: the genuine joy of a crackling fire on a cold night, and the very genuine frustration of hauling wood, cleaning ash, managing smoke, and dealing with a fireplace that requires real effort every single time you want to use it.
For many Bergen, Passaic, Morris, and Essex county homeowners, wood-to-gas conversion is the answer — and it’s one of the most popular services we perform at KJB Fireplaces. But is it right for your home and your lifestyle? This guide will walk you through everything you need to know to make the decision confidently.
What Is a Wood-to-Gas Conversion?
A wood-to-gas fireplace conversion involves installing a gas insert — a self-contained firebox unit — into your existing wood-burning fireplace opening. The insert connects to your home’s natural gas line (or a propane tank in homes without natural gas), and a new liner is run through your existing chimney to safely vent exhaust.
The result: your existing firebox, surround, and mantel stay in place, but the interior is now a clean, efficient, remote-controlled gas fireplace. Most conversions are completed in a single day and require minimal disruption to your home.
5 Signs a Conversion Might Be Right for You
1. You Love Your Fireplace’s Look But Hate the Maintenance
Gas inserts are designed to fit within existing fireplace openings, so you keep your current surround, mantel, and hearth. If you’re happy with how your fireplace looks but exhausted by the work of maintaining a wood-burning system, conversion gives you the best of both worlds.
2. You’re Not Using Your Fireplace Enough
If your wood-burning fireplace sits unused most of the winter because starting a fire feels like too much effort for a Tuesday evening, a gas conversion will almost certainly change your habits. The ability to have a fire in 30 seconds dramatically increases how often homeowners actually use their hearths.
3. You’re Concerned About Air Quality
Wood-burning fireplaces are significant sources of particulate emissions — a growing concern for homeowners and municipalities across New Jersey. Many Bergen County towns have adopted seasonal burn restrictions. Gas inserts burn cleanly, producing minimal emissions and complying with all NJ air quality regulations.
4. Your Chimney Needs Expensive Repairs
If your existing chimney liner is cracked or deteriorated — a common issue in older Northern NJ homes — you may be facing a costly repair just to keep your wood-burning fireplace usable. In many cases, the cost of a full chimney relining is comparable to the cost of a gas insert conversion that includes a new stainless steel liner. The conversion often represents better value.
5. You Want Supplemental Heat You Can Control
Modern gas inserts are highly efficient heating appliances. Many models are rated at 70 to 85 percent efficiency and can meaningfully warm a 1,000 to 2,000 square foot area with precise thermostat control. If you want your fireplace to do real heating work — not just look good — gas is the superior choice.
What About the Authentic Fire Experience?
The most common objection we hear is: ‘But I love the real fire experience.’ It’s a completely legitimate concern, and we respect it. Here’s the honest answer: today’s gas inserts have made enormous advances in flame realism. High-end models feature layered log sets, glowing ember beds, and variable flame heights that many homeowners find nearly indistinguishable from real wood fires at a conversational distance.
That said — if the smell of wood smoke and the crackling sound of a real fire are non-negotiable for you, a gas insert won’t fully replicate them. What we typically find, though, is that once homeowners experience the convenience of gas, the trade-off feels very comfortable.
KJB Tip: Visit our Ramsey showroom to see gas insert models burning live. Many homeowners who come in skeptical leave convinced — the modern flame realism is genuinely impressive.

Cost of Wood-to-Gas Conversion in NJ
Most wood-to-gas conversions in Bergen, Passaic, Morris, and Essex counties range from $2,500 to $5,500 depending on the insert selected, the condition of the existing chimney, and gas line access. This is a competitive investment compared to the ongoing costs of firewood, chimney sweeping, and the value of your time.
Is Your Home a Good Candidate?
Most homes with existing wood-burning fireplaces are excellent candidates for conversion. The key requirements are a functioning firebox and chimney, and either an existing natural gas line within a reasonable run or a propane tank option. Our in-home consultation will quickly determine whether your home qualifies and what the project will realistically involve.
