Cost to finish a basement with drywall, insulation, and flooring

A basement finish focused on insulation, drywall, and flooring — without a bathroom addition — typically runs $22,000 to $55,000 in the Lehigh Valley. This covers framing, insulation, drywall, paint, flooring, lighting, and trim across a standard footprint.

Costs climb with square footage, premium flooring, recessed lighting counts, and any moisture work needed before finishing.

What affects the cost

• Square footage — The single biggest driver of materials and labor.
• Insulation & framing — Full perimeter framing and insulation for comfort and code.
• Flooring type — LVP, carpet, or tile each carry different costs.
• Lighting plan — Recessed light count and switching.
• Moisture prep — Any waterproofing needed before finishing.
• Trim & doors — Baseboard, casing and interior doors.
