Fireplace & Built-ins

Fireplaces and built-ins: the highest impact living room upgrade

The fireplace and built-in wall is the visual anchor of most living rooms. A well-designed fireplace surround with custom millwork on both sides reads as expensive even when the rest of the room is modest. Conversely, a dated brick fireplace with no built-ins drags down an otherwise beautiful room.

2026 pricing in major US metros: $4,000 to $9,000 for a refresh, $12,000 to $20,000 for a standard project with linear gas insert and partial built-ins, $25,000 to $50,000 for premium custom work with full millwork and natural stone slab.

The built-in decision

Built-ins on either side of a fireplace add 30 to 50 percent visual impact for 30 to 50 percent of the project cost. They store books and media, add architectural depth to a flat wall, and read as custom even with stock cabinetry painted on-site.

Standard depth: 16 to 24 inches. Standard width: 30 to 48 inches per side. Mix open shelves (top half) with closed cabinetry (bottom half) for the most flexible storage. Add LED puck lights inside the open shelves for a magazine-photo glow.

What national 2026 data says about fireplace costs

The 2026 cost ranges in this guide track three primary sources. NAHB remodeling member surveys consistently put fireplace refresh projects in the $3,800 to $8,500 band for like-for-like swaps, with linear gas insert upgrades pushing $11,000 to $22,000 once millwork is included. BLS Occupational Employment & Wages data for stonemasons and fireplace installers anchors the labor side of the math: median hourly wage for masonry workers ran $25.16 in the most recent BLS release, with the 75th percentile (typical for licensed fireplace specialists in California, Washington, and Colorado) reaching $33+. Trade publication Remodeling Magazine’s Cost vs Value report places a major fireplace surround project at roughly 65% to 75% resale return in West Coast and Mountain West metros, which is why this category clears ROI gates that pure cosmetic upgrades rarely do.

One number worth flagging: the gas-line trades labor cost has climbed faster than materials in 2025-2026. NAHB’s 2026 member survey reports a 14% YoY jump in gas-installer labor in California specifically (San Diego and LA metros most affected), pushing total project cost ~6% to 9% above the materials-only estimate most homeowners start with.

Permit and code basics

Gas line work always needs a permit. Most cities issue fireplace permits in 2 to 3 weeks. Both most US states require licensed plumbers for gas connections. Clearance to combustibles (typically 12 inches above and 4 inches to the sides) must be maintained per the manufacturer spec sheet, which the inspector will verify.
