One of the most common questions we hear from Northern New Jersey homeowners is a simple one: what’s this going to cost me? It’s a fair question, and we believe in giving honest, transparent answers — not vague ranges designed to get you in the door.
The reality is that fireplace installation costs in New Jersey vary significantly based on the type of fireplace, the complexity of the installation, your home’s existing setup, and the quality of the unit you choose. In this guide, we’ll break down realistic cost ranges for 2026 across every major fireplace type, explain what drives price differences, and show you how to get the most value from your investment.
The Factors That Affect Fireplace Installation Cost in NJ
Before we get to numbers, it’s important to understand what goes into a fireplace installation quote:
- Fireplace type (gas, wood-burning, electric, or insert)
- Whether your home already has a chimney or gas line
- The brand and model of the unit selected
- Any custom work: mantel, surround, hearth pad, or refacing
- Local permit requirements (NJ requires permits for gas appliance installation)
- Labor — varies by contractor experience and project complexity
KJB Tip: The cheapest quote is rarely the best value. In our 20+ years serving Bergen County, we’ve repaired many jobs done by low-bid contractors that ultimately cost homeowners far more than a quality installation would have.
Gas Fireplace Installation Cost in New Jersey
Gas Direct-Vent Fireplaces: $3,500 – $8,500+
This is the most popular fireplace type we install throughout Bergen, Passaic, Morris, and Essex counties. A gas direct-vent fireplace draws combustion air from outside through a sealed pipe system, making it safe for any room in the home without a traditional chimney.
- Unit cost: $1,500 – $5,000+ depending on brand, size, and features
- Installation labor: $1,000 – $2,500 depending on complexity
- Gas line extension (if needed): $200 – $800
- Permits: $100 – $300 depending on municipality
Higher-end models with realistic log sets, remote thermostats, and designer fronts will sit at the top of this range. Entry-level units from reputable brands can be installed for considerably less.
Gas Fireplace Inserts: $2,500 – $6,500
An insert fits into an existing wood-burning fireplace opening, effectively converting it to gas. This is a cost-effective option for homeowners who already have a functioning firebox and chimney.
- Unit cost: $1,200 – $4,000
- Installation: $800 – $1,800 (liner installation included)
- Existing gas line required or gas line extension needed
Wood-Burning Fireplace Installation Cost in New Jersey
Prefabricated Wood-Burning Fireplaces: $2,500 – $6,000
A prefabricated or zero-clearance wood-burning unit can be installed in a framed chase without traditional masonry. These are popular in newer NJ construction.
Masonry Fireplace (New Construction): $8,000 – $25,000+
A true masonry fireplace, built from scratch with brick or stone, is the most expensive option. Costs vary dramatically based on materials, the mason’s rates, and the design complexity. This is typically a new-construction choice or a major renovation project.
Wood-to-Gas Conversion Cost in New Jersey
Conversion with Gas Insert: $2,500 – $5,500
Converting an existing wood-burning fireplace to gas is one of the best value investments a Bergen County homeowner can make. You preserve your existing firebox and mantel while gaining all the benefits of gas — convenience, cleaner burning, and controllable heat. Most conversions are completed in one day.
Fireplace Refacing Cost in New Jersey
Cosmetic Refacing: $1,500 – $6,000+
If your fireplace functions well but looks dated — think 1990s brass trim, old brick, or a worn surround — refacing can transform the look of your hearth without touching the mechanical components. Cost varies based on materials chosen: tile, stone, marble, and shiplap all carry different price points.
What About Mantels & Surrounds?
A new mantel and surround can add $500 to $5,000+ to a project depending on the material and custom work involved. KJB Fireplaces carries a wide selection of mantels for every style and budget — from classic wood in traditional Bergen County colonials to sleek stone for modern open-plan homes.
Does a Fireplace Add to My Home’s Value?
Consistently yes. The National Association of Real Estate Appraisers estimates that a fireplace can increase a home’s resale value by 6 to 8 percent. In competitive Northern NJ markets like Ridgewood, Ho-Ho-Kus, Upper Saddle River, and Tenafly, a beautiful fireplace can meaningfully differentiate your home from comparable listings.
