Converting your wood-burning fireplace to gas in New London is a smart move for safety, convenience, and home value. These 7 upgrades ensure your new gas system meets local codes, handles coastal moisture, and delivers cozy warmth all winter long.
1. Why New London homeowners are switching from wood to gas fireplaces
A gas fireplace conversion in New London isn’t just about convenience—it’s about safety, efficiency, and protecting your home from the elements. New London’s coastal climate brings salty air, high humidity, and freeze-thaw cycles that accelerate wood-burning chimney wear. Gas burns cleaner, produces no creosote, and eliminates the need to store firewood near your home. Plus, with rising insurance premiums tied to wood-burning systems, many local homeowners are making the switch to reduce risk and maintenance. Learn more about local chimney risks
2. Upgrade #1: Install a direct-vent gas fireplace insert for coastal homes
A direct-vent gas fireplace insert is the gold standard for New London homes, especially those near the water in neighborhoods like Ocean Beach or across from Fort Trumbull. Unlike vent-free models, direct-vent systems pull combustion air from outside and expel exhaust through a sealed pipe, preventing moisture and salt corrosion inside your flue. This setup is ideal for older chimneys that may already show wear from decades of wood burning. The Chimney Safety Institute of America recommends direct-vent systems for coastal homes due to their superior safety and efficiency. Request a free estimate for your insert
3. Upgrade #2: Seal and waterproof your chimney before the conversion
Before installing a gas fireplace, your chimney must be in top shape. New London’s freeze-thaw cycles can crack masonry, and salty air accelerates deterioration. A professional chimney sweep and inspection will identify cracks, damaged flue tiles, or deteriorating mortar. Once repaired, applying a breathable waterproofing sealant protects the chimney from moisture while allowing vapor to escape. This step is critical—ignoring it can lead to water damage, mold, and costly repairs down the road. Schedule your pre-conversion inspection
4. Upgrade #3: Add a stainless steel chimney liner for durability
If your chimney is unlined or has an old clay tile liner, upgrading to a stainless steel liner is a smart investment for New London homes. Stainless steel resists corrosion from salty air and handles the heat of gas combustion better than older materials. It also improves draft and reduces the risk of carbon monoxide leaks. For homes in areas like Winthrop or downtown New London, where chimneys may be exposed to harsh coastal winds, a flexible or rigid stainless steel liner ensures long-term performance.

5. Upgrade #4: Install a smart thermostat and remote control for effortless warmth
Modern gas fireplaces in New London homes can integrate with smart home systems for ultimate convenience. A Wi-Fi-enabled thermostat lets you control your fireplace from your phone, while remote controls eliminate the need to get up from your couch. This is especially useful during New London’s unpredictable winters, where temperatures can drop quickly. Smart systems also allow you to set schedules, ensuring your home is cozy when you arrive without wasting energy. See our smart fireplace upgrade options
6. Upgrade #5: Upgrade your gas line and ensure proper venting
A gas fireplace conversion requires a properly sized gas line to handle the new appliance’s demand. Older homes in New London’s historic districts, like the Point or Downtown, may need an upgraded gas line to accommodate the fireplace’s BTU output. Additionally, ensure your venting system is correctly sized and installed to prevent backdrafting, which can introduce carbon monoxide into your home. A licensed plumber and chimney professional should work together to ensure everything meets local codes and manufacturer specifications. Get a free gas line assessment
7. Upgrade #6: Add a decorative surround and hearth for a custom look
A gas fireplace conversion is the perfect time to refresh your living space with a custom surround and hearth. Whether you prefer sleek modern tile, rustic stone, or classic wood, the options are endless. In New London, where historic charm meets modern living, a well-designed fireplace can enhance your home’s aesthetic and resale value. Consider materials that complement your home’s architecture, such as brick for colonial-style homes in the Fitchville area or slate for contemporary spaces in Ocean Beach.

8. What to expect during and after your New London gas fireplace conversion
A typical gas fireplace conversion in New London takes 1–3 days, depending on the complexity of your chimney and the upgrades needed. Your installer will begin with a thorough inspection and chimney cleaning to ensure everything is safe and ready. Next, they’ll install the insert, liner, and venting system, followed by gas line adjustments and final testing. After installation, schedule a post-conversion inspection to confirm everything is operating correctly and safely. Many local homeowners pair this project with other upgrades, like adding a stainless steel cap to protect against coastal debris. Plan your conversion timeline
A chimney inspection is a non-negotiable first step before any gas fireplace conversion
A chimney inspection is a thorough evaluation of your chimney’s condition, including the flue, liner, masonry, and structural components. For New London homes, this step is critical due to the coastal climate’s impact on chimneys. The inspection will identify cracks, blockages, or deterioration that could compromise the safety of your new gas fireplace. The Chimney Safety Institute of America recommends a Level 2 inspection for any fireplace conversion, which includes a video scan of the flue. Skipping this step risks hidden damage going unnoticed until it becomes a costly problem. Book your pre-conversion inspection today
How to choose the right contractor for your New London gas fireplace conversion
Not all chimney and fireplace contractors are created equal, especially in a city like New London with its mix of historic and modern homes. Look for a licensed, insured professional with experience in gas fireplace conversions and local climate challenges. Ask for references from nearby homeowners in neighborhoods like Ledyard or Waterford, and verify their certifications with the Chimney Safety Institute of America. A reputable contractor will provide a detailed estimate, explain the process clearly, and offer warranties on labor and parts.

What’s the difference between vented and vent-free gas fireplaces for New London homes?
Vented gas fireplaces expel exhaust outside through a chimney or vent pipe, making them safer and more efficient for New London’s humid climate. Vent-free models release combustion byproducts into your home, which can contribute to moisture buildup and indoor air quality issues. The Chimney Safety Institute of America recommends vented systems for all homes, especially those near the coast.
