Door hardware installation costs can vary significantly based on several factors. On average, installation costs range from $120 to $350 per opening, depending on the hardware type and regional labor rates. This guide provides insights into what influences these costs and how to manage them effectively.
1. Hardware Type: Basic knobs start at $18, while advanced smart locks can exceed $350.
2. Door Material: Hollow-core doors are cheaper to install than solid-core or metal doors.
3. Prep Requirements: Retrofitting may require additional labor for drilling or mortising.
4. Finish Level: Specialty finishes can increase both material and labor costs.
5. Quantity & Repetition: Larger projects benefit from reduced setup time.
Project: 2,800 ft² custom home – 24 interior doors, 1 main entry, 1 garage entry
Total Cost: $1,819.70
Costs can vary by region. For example, installation in Houston may be 12-15% cheaper than in coastal California due to labor rate differences.
Use real-time data to adjust estimates and avoid overestimating. Consider factors like material volatility and regional labor rates to keep costs in check.
