Fireplace Installation and Remodel Cost Guide
Fireplace projects cost $1,500–$5,000 for a surround remodel, $3,000–$8,000 for a gas insert installation, $5,000–$15,000 for a new gas fireplace with venting, and $8,000–$25,000+ for a new masonry fireplace. Electric fireplace installations run $1,000–$4,000. Linear gas fireplaces for modern designs cost $5,000–$12,000 for the unit plus $3,000–$8,000 for installation and surround.
Fireplaces remain one of the most desired features in American homes, and fireplace projects — from simple surround remodels to complete new installations — offer remodeling contractors strong margins with high perceived value. Whether clients want to update a dated brick surround, convert a wood-burning fireplace to gas, or install a sleek linear fireplace in a modern renovation, understanding the costs and installation requirements is essential for accurate estimating.
Gas Fireplace Insert Installation
Gas inserts fit into existing wood-burning fireplaces and are the most common fireplace upgrade. A direct-vent gas insert from Napoleon, Regency, or Majestic costs $2,000–$5,000 for the unit. A premium insert from Heat & Glo, Valor, or Mendota runs $3,500–$7,000. Installation involves running a flexible aluminum or stainless steel liner through the existing chimney ($500–$1,500 depending on chimney height), extending or installing a gas line ($500–$1,500 for a licensed plumber or gas fitter), electrical for the blower and ignition ($200–$500), and finishing the surround ($500–$2,000). Total installed cost for a gas insert: $3,000–$8,000. The existing chimney must be inspected before installation — a damaged flue liner or structural issues must be addressed first. A chimney inspection costs $150–$400 and should be included in your assessment. Gas inserts provide 25,000–40,000 BTU and can heat 1,000–1,500 sq ft, making them functional heating appliances as well as aesthetic features. Remote controls and thermostatic operation are standard on mid-range and premium units.
New Gas Fireplace Installation
When no existing fireplace exists, a new direct-vent gas fireplace can be installed on virtually any exterior wall. The fireplace vents horizontally through the wall — no chimney needed. A standard direct-vent gas fireplace from Napoleon, Majestic, or Heatilator costs $2,000–$5,000 for the unit. Linear (contemporary) gas fireplaces from Napoleon Vector, Heat & Glo Mezzo, or DaVinci Custom run $4,000–$12,000 for the unit — these wide, sleek units are the top trend in modern home design. Installation includes framing a fireplace alcove in the wall ($500–$1,500), cutting through the exterior wall for the vent terminal ($300–$600), running a gas line ($500–$1,500), electrical for the ignition and blower ($200–$500), and building the surround and mantel ($1,000–$5,000). Total installed cost for a new gas fireplace: $5,000–$15,000 for standard units and $10,000–$25,000+ for premium linear units with custom surrounds. Ventless (vent-free) gas fireplaces are an alternative at lower cost ($1,500–$4,000 installed) but are prohibited in some states and municipalities and produce moisture that can cause condensation issues. Always recommend direct-vent over ventless.
Fireplace Surround and Mantel Remodeling
Surround remodels update the appearance of an existing fireplace without changing the firebox. This is a high-margin project with material costs of $500–$3,000 and labor of $1,000–$3,000. Options by material: painted drywall with a simple wood mantel is the most budget-friendly at $1,000–$2,500. Tile surrounds (subway tile, marble mosaic, porcelain large-format) cost $1,500–$4,000 — popular tile brands include Daltile, MSI, and Jeffrey Court. Natural stone (marble slab, limestone, travertine) surrounds run $2,500–$6,000 for materials and installation. Stacked stone veneer (Eldorado, Cultured Stone, AirStone) from floor to ceiling costs $3,000–$8,000 and creates a dramatic focal point. Shiplap or wood plank surrounds cost $1,500–$3,500 — a popular farmhouse and coastal look. A custom wood mantel from a millwork shop costs $300–$1,500 depending on style and species. Reclaimed wood beam mantels ($200–$800 for the beam, $200–$400 for installation) are on-trend and offer great margins. Concrete surrounds (poured-in-place or precast from a company like Trueform Concrete) run $2,000–$5,000 for a modern industrial look. The surround remodel is an excellent add-on to living room or whole-house renovations — always ask whether the client wants to update the fireplace when you are already working in the room.
Electric Fireplace Installations
Electric fireplaces have improved dramatically in flame realism and are increasingly popular in condos, apartments, and homes where gas lines are unavailable. A recessed linear electric fireplace from Dimplex, Napoleon, or Amantii costs $800–$3,000 for the unit. Installation involves framing a wall recess ($300–$800), running a dedicated 120V or 240V circuit ($200–$500), and finishing the surround ($500–$2,000). Total installed cost: $1,500–$5,000. Electric fireplaces can be installed on any wall — no venting, gas line, or chimney required, making them the simplest fireplace to add during a renovation. Wall-mounted electric fireplaces ($300–$1,500 for the unit) require minimal installation — just a dedicated outlet and mounting hardware at $200–$500 installed. Built-in electric fireplace media walls are a growing trend: a full wall unit with a recessed fireplace, TV niche, and floating shelves or cabinets costs $3,000–$10,000. Dimplex Ignite XL (50-inch, 60-inch, or 74-inch) and Napoleon Alluravision are the most popular linear electric units. While electric fireplaces produce supplemental heat (up to 5,000 BTU), they are primarily aesthetic — present them as design features, not heating solutions.
Masonry Fireplaces and Chimney Work
New masonry fireplaces are the most expensive option at $8,000–$25,000+ but provide the authentic experience many homeowners desire. A standard masonry fireplace with a brick or stone face, concrete block chimney with a clay flue liner, and a simple wood mantel costs $8,000–$15,000. A custom masonry fireplace with a natural stone face, oversized opening, raised hearth, and decorative chimney runs $15,000–$30,000. Masonry fireplace construction requires a concrete footing (the fireplace and chimney weigh 5,000–10,000 lbs), so first-floor installation on an existing home requires foundation work adding $2,000–$5,000. Chimney repairs and rebuilds on existing fireplaces are a separate revenue stream: chimney cap replacement ($200–$600), crown repair ($500–$1,500), tuckpointing ($10–$25 per sq ft), flue liner installation ($1,500–$4,000), and full chimney rebuild above the roofline ($3,000–$10,000). Partner with or subcontract to a certified chimney specialist (CSIA-certified) for chimney inspection and repair work. Include chimney condition in your assessment whenever a fireplace is part of a renovation scope.
Pricing Strategy and Upselling Opportunities
Fireplace projects should target 40–50% gross margin. The high perceived value of fireplaces (they consistently top desired home features lists) supports premium pricing. Present fireplace projects as complete packages including the firebox, surround, mantel, and any gas or electrical work — not as component parts. Upselling opportunities: when a client is remodeling a living room, always ask about the fireplace. A $2,000–$5,000 surround remodel added to a $30,000 living room renovation increases your revenue with minimal additional scheduling. Fireplace remote control and smart home integration ($200–$500) adds convenience and margin. Decorative log sets, glass media, and fire stones ($100–$500) personalize gas fireplaces. A fireplace accent wall with built-in shelving or cabinetry flanking the fireplace costs $3,000–$10,000 and transforms the entire room. Bundle fireplace surround remodels with mantel installation and TV mounting for a complete living room focal point package at $3,000–$8,000. Payment: 50% deposit for material procurement, 50% at completion. Lead times for gas fireplaces and inserts are typically 1–3 weeks; custom mantels and stone surrounds may take 3–6 weeks.
