How Much Does Gas Fireplace Installation Cost in Long Island and NYC?
Thinking about adding a gas fireplace to your home in Long Island or New York City? You’re not alone. A gas fireplace is one of the most popular home upgrades today — it delivers real flames, reliable heat, and modern comfort without the mess of wood. But before choosing a model or visiting a showroom, most homeowners ask the same question: how much will installation actually cost?
The answer isn’t as simple as a single number. Prices vary depending on whether you’re converting an existing fireplace, installing a brand-new unit, or designing a custom feature wall. Venting routes, gas line access, finishing materials, and even building layout all play a major role — especially in NYC and Long Island homes where construction standards and labor requirements differ from national averages.
In this guide, we break down realistic installation costs based on real projects in the area. You’ll learn what affects pricing, what installers actually do during installation, and how to avoid expensive mistakes before committing to a fireplace purchase.
