For construction professionals, understanding the labor cost to replace a door knob is crucial for accurate project planning. Typical costs range from $45 to $150+, depending on factors such as door condition and lock type. This guide provides insights into the variables affecting labor costs and offers strategies to optimize efficiency.
• Existing door condition: Swollen or misaligned doors require additional time for adjustments.
• Lock type: Privacy locks are quicker to install than keyed entry knobs.
• Door material: Solid core doors may require more effort than hollow core doors.
• Travel and site prep: High-rise installations may involve additional time for access.
• Urgency: After-hours or same-day services often incur higher rates.
1. Straight swap (no latch plate changes): $45–$65
2. Retrofit to a different backset or bore size: $65–$95
3. Upgrade to smart keyless knob with app setup: $95–$150+
